101. Method P avoids drugs and devices and depends on timing or behaviour to reduce sperm-ovum meeting. Method Q uses a physical structure placed before coitus to block semen or sperm entry. Their most appropriate classification is:
ⓐ. P as surgical and Q as hormonal
ⓑ. P as natural and Q as barrier
ⓒ. P as intrauterine and Q as natural
ⓓ. P as hormonal and Q as surgical
Correct Answer: P as natural and Q as barrier
Explanation: Method P is defined by the absence of contraceptive drugs or devices and by reliance on behavioural timing or physiological conditions that reduce opportunities for sperm and ovum to meet. That description fits the natural-method category. Method Q uses a physical structure placed before intercourse to obstruct entry of semen or sperm, which is the defining logic of a barrier method. The comparison separates categories according to their mode of intervention rather than their shared final aim of preventing pregnancy. Natural methods depend mainly on behaviour or temporary reproductive conditions, whereas barrier methods introduce a physical obstruction. This classification provides the conceptual bridge from natural contraception to the next major group of contraceptive methods.
102. Use the arrangement described below. Structure P is a thin rubber or latex sheath placed over the penis before coitus. Structure Q is a barrier positioned within the female reproductive tract before coitus. The shared contraceptive principle of P and Q is:
ⓐ. prevention of ejaculated semen from entering the female reproductive tract
ⓑ. suppression of ovulation by releasing reproductive hormones
ⓒ. destruction of ova after they enter the fallopian tube
ⓓ. permanent interruption of gamete transport through reproductive ducts
Correct Answer: prevention of ejaculated semen from entering the female reproductive tract
Explanation: Male and female condoms are barrier contraceptives. The male condom is worn over the penis, whereas the female condom is positioned within the female reproductive tract before intercourse. Despite this difference in placement, both operate through the same basic physical principle: they prevent ejaculated semen, and sperm, from entering or progressing through the female reproductive tract. They do not inhibit ovulation, destroy ova or permanently interrupt reproductive ducts. The important reasoning step is to distinguish anatomical placement from biological action. Two devices may be positioned differently yet belong to the same contraceptive category as both reduce the opportunity for sperm to reach an ovum by creating a physical barrier during coitus.
103. A contraceptive figure shows a thin latex covering fitted over the penis before intercourse. A second figure shows a barrier inserted within the female tract around the vaginal and cervical region. The most accurate comparison is:
ⓐ. only the first is a barrier contraceptive
ⓑ. only the second can prevent semen entry
ⓒ. both require placement inside the uterus by trained personnel
ⓓ. both are condom-type barriers used before coitus, but their anatomical placement differs
Correct Answer: both are condom-type barriers used before coitus, but their anatomical placement differs
Explanation: The first description corresponds to a male condom, while the second corresponds to a female condom. Both belong to the barrier category and are used before coitus to reduce the chance that sperm will enter the female reproductive tract and reach an ovum. Their important difference is anatomical placement: one is placed over the penis and the other within the female tract. Neither is inserted into the uterus by a doctor or expert nurse, which would describe an intrauterine device rather than a condom. The comparison depends on separating a shared contraceptive mechanism from a different site of placement. Barrier classification is determined by the physical obstruction they provide, not by identical positioning.
104. Nirodh is correctly classified as:
ⓐ. a male condom belonging to the barrier-method category
ⓑ. a non-medicated intrauterine contraceptive device
ⓒ. a reusable cervical barrier used with spermicide
ⓓ. a hormone-releasing contraceptive implanted under the skin
Correct Answer: a male condom belonging to the barrier-method category
Explanation: Nirodh is an example of a male condom. A male condom is a thin rubber or latex barrier placed over the penis before coitus so that ejaculated semen does not enter the female reproductive tract. Its classification follows from this physical mechanism: it belongs to the barrier group of contraceptives. This differs from intrauterine devices, which are placed inside the uterus, from reusable female cervical barriers such as diaphragms or cervical caps, and from hormone-containing implants placed under the skin. The name of a contraceptive should be connected to its method category and anatomical use rather than memorised in isolation. Nirodh represents the male-condom form of barrier contraception.
105. Consider the following statements about male and female condoms.
I. Both are used before coitus.
II. Both act primarily by preventing semen or sperm from entering the female reproductive tract.
III. Both are inserted into the uterine cavity by trained medical personnel.
IV. Their anatomical placement differs even though their barrier principle is similar.
ⓐ. I and III only
ⓑ. II and III only
ⓒ. I, II and IV only
ⓓ. I, II, III and IV
Correct Answer: I, II and IV only
Explanation: Male and female condoms are both barrier contraceptives used before intercourse. Their common biological function is to reduce the chance that sperm will enter or progress through the female reproductive tract, thereby lowering the probability of sperm-ovum meeting. Their sites of placement differ because the male condom is worn on the penis whereas the female condom is positioned within the female reproductive tract. Statement III is incorrect because uterine insertion by a doctor or expert nurse is characteristic of an intrauterine device, not a condom. Statements I, II and IV capture the common mechanism and the placement difference without confusing condoms with devices that require professional insertion into the uterus.
106. A couple wants a reversible contraceptive that they can use themselves and also wants protection against sexually transmitted infections. Among the major contraceptive categories, the most appropriate choice is:
ⓐ. a condom
ⓑ. an intrauterine device
ⓒ. an oral hormonal pill
ⓓ. a surgical sterilisation method
Correct Answer: a condom
Explanation: The case contains two independent requirements: prevention of pregnancy and reduction of sexually transmitted infection risk. Condoms are particularly suited to this combination since they form a physical barrier that limits semen and sperm entry while also reducing direct exchange of potentially infectious sexual fluids. They can be used by the individuals themselves and do not require surgical sterilisation or professional placement in the uterus. Oral contraceptive pills and intrauterine devices can prevent pregnancy through other mechanisms, but their contraceptive action does not provide the same barrier against STI transmission. The decisive evidence is the need for dual protection. When both pregnancy prevention and STI-risk reduction are required, condom use matches both conditions of the case.
107. If a couple switches from consistent condom use to a contraceptive method that prevents pregnancy effectively but creates no physical barrier during intercourse, the most important protection that may be lost is:
ⓐ. prevention of implantation in the uterus
ⓑ. suppression of sperm formation in the testes
ⓒ. permanent blockage of the fallopian tubes
ⓓ. reduction of sexually transmitted infection risk through barrier protection
Correct Answer: reduction of sexually transmitted infection risk through barrier protection
Explanation: Condoms have an important dual role. They help prevent conception by blocking semen or sperm entry, and the same physical barrier also lowers the risk of transmission of sexually transmitted infections, including infections associated with AIDS. A contraceptive that prevents pregnancy through hormonal action, intrauterine effects or another non-barrier mechanism may retain contraceptive effectiveness but does not automatically reproduce this STI-protection advantage. The changed condition in the described situation is the loss of a physical barrier during intercourse. The consequence to predict is the loss of barrier-based reduction in STI transmission risk. Condoms form a physical barrier to semen entry and also reduce STI transmission risk, while cervical barriers mainly cover the cervix to impede sperm passage. Pregnancy prevention and infection prevention are related benefits of condoms but should not be assumed to accompany every contraceptive method.
108. Review the following features of condoms.
I. Male and female condoms can help prevent conception.
II. They can also reduce the risk of sexually transmitted infections.
III. They are intended for permanent reuse over many cycles.
IV. They can be used without requiring insertion into the uterus by a medical professional.
ⓐ. I and III only
ⓑ. I, II and IV only
ⓒ. II, III and IV only
ⓓ. I, II, III and IV
Correct Answer: I, II and IV only
Explanation: Condoms combine contraceptive and protective features. Their barrier action reduces the chance that sperm will enter the female reproductive tract and reach an ovum, so they can prevent conception. The same physical separation also helps reduce transmission of sexually transmitted infections. They do not require insertion into the uterine cavity by a doctor or expert nurse, which distinguishes them from intrauterine devices. Statement III is incorrect as male and female condoms are described as disposable rather than reusable contraceptive devices. Statements I, II and IV identify the contraceptive, STI-protection and user-controlled features of condoms. This combination explains why condoms occupy a distinctive place among contraceptive methods even though several other methods can also prevent pregnancy.
109. Four contraceptive profiles are shown below.
| Profile | Pregnancy prevention | STI protection | User-controlled placement | Disposable |
| P | Yes | Yes | Yes | Yes |
| Q | Yes | No | No | No |
| R | Yes | No | Yes | No |
| S | No | Yes | No | Yes |
The profile most consistent with a condom is:
ⓐ. Profile Q
ⓑ. Profile R
ⓒ. Profile P
ⓓ. Profile S
Correct Answer: Profile P
Explanation: A condom is characterised by a combination of features rather than by pregnancy prevention alone. Diaphragms, cervical caps and vaults are reusable female barriers that may be combined with spermicidal creams, jellies or foams. It acts as a barrier against sperm entry, so it can prevent conception. The same barrier also reduces the risk of sexually transmitted infection transmission. Condoms are used by the individuals themselves rather than being inserted into the uterus by a medical professional, and they are described as disposable. Profile P is the only row combining all four of these characteristics. The table requires synthesis across several columns instead of recognition of one isolated fact. This combination also distinguishes condoms from many other contraceptives that may be effective against pregnancy but lack barrier-based STI protection or require professional placement.
110. Match each condom-related feature with the implication it most directly supports. A Column II entry is used once.
| Column I | Column II |
| P. Physical barrier to semen entry | 1. Reduced probability of sperm-ovum meeting |
| Q. Barrier during sexual contact | 2. Reduced STI transmission risk |
| R. Self-insertable use | 3. User control without professional insertion |
| S. Disposable nature | 4. Use as a non-reusable barrier |
ⓐ. P-2, Q-1, R-4, S-3
ⓑ. P-3, Q-4, R-1, S-2
ⓒ. P-1, Q-3, R-2, S-4
ⓓ. P-1, Q-2, R-3, S-4
Correct Answer: P-1, Q-2, R-3, S-4
Explanation: The contraceptive value of condoms begins with their physical barrier, which reduces the likelihood that sperm will enter the female reproductive tract and meet an ovum. During sexual contact, this barrier also limits exchange of potentially infectious fluids and thereby contributes to reduced STI transmission risk. Their self-insertable or self-applied nature means that users do not depend on a doctor or expert nurse for placement each time. Their disposable nature distinguishes them from reusable female barriers such as diaphragms, cervical caps and vaults. Condoms form a physical barrier to semen entry and also reduce STI transmission risk, while cervical barriers mainly cover the cervix to impede sperm passage. The mapping connects each structural or practical feature with its direct reproductive-health consequence, showing that condom use combines biological protection with important user-controlled characteristics.
111. A person wants privacy in contraceptive use and wishes to avoid a method requiring a clinic visit for placement. At the same time, protection against STI transmission is important. The most suitable method is:
ⓐ. a condom used before coitus
ⓑ. an intrauterine device inserted by a trained professional
ⓒ. a hormone-releasing intrauterine device
ⓓ. a copper-releasing intrauterine device
Correct Answer: a condom used before coitus
Explanation: The clues in the case point toward a method that is user controlled, does not require professional insertion and also provides barrier-based protection against sexually transmitted infections. Condoms satisfy all of these conditions. Male and female condoms can be used by the individuals themselves, offer privacy and are disposable. Their physical barrier also contributes to both pregnancy prevention and reduction of STI transmission risk. Intrauterine devices, whether copper releasing or hormone releasing, are placed inside the uterus through the vagina by a doctor or expert nurse. They are contraceptive methods but do not match the same user-placement and STI-protection profile. The combination of privacy, self-use and dual protection makes the condom the appropriate choice.
112. Assertion: A diaphragm can be reused, whereas a condom is generally treated as a disposable barrier.
Reason: Both methods are inserted into the uterine cavity by a doctor before intercourse.
ⓐ. Both Assertion and Reason are true, and Reason correctly explains Assertion
ⓑ. Both Assertion and Reason are true, but Reason does not explain Assertion
ⓒ. Assertion is true, but Reason is false
ⓓ. Assertion is false, but Reason is true
Correct Answer: Assertion is true, but Reason is false
Explanation: The Assertion correctly distinguishes two kinds of barrier contraceptive. Diaphragms, cervical caps and vaults are reusable female barriers, whereas male and female condoms are described as disposable. The Reason is false since neither category is defined by professional insertion into the uterine cavity. Diaphragms, cervical caps and vaults are placed to cover the cervix and block sperm entry, while condoms are positioned on the penis or within the female tract before coitus. Professional insertion into the uterus is instead characteristic of intrauterine devices. The biological distinction concerns both a practical difference in reuse and an anatomical distinction. Confusing cervical barriers with intrauterine devices would assign them the wrong location and method of placement.
113. A reusable female contraceptive is placed so that it covers the cervix and blocks sperm entry. Its effectiveness may be increased by adding a spermicidal cream or jelly. The missing contraceptive category is best represented by:
ⓐ. a copper-releasing IUD
ⓑ. a diaphragm, cervical cap or vault
ⓒ. a male condom
ⓓ. a subcutaneous hormonal implant
Correct Answer: a diaphragm, cervical cap or vault
Explanation: Diaphragms, cervical caps and vaults are reusable female barrier contraceptives placed so that they cover the cervix and impede sperm entry into the uterus. Their barrier function may be supplemented with spermicidal preparations such as creams, jellies or foams. This combination improves contraceptive efficiency by pairing a physical obstruction with a chemical agent that acts against sperm. A male condom is also a barrier, but it is not a reusable cervical covering. An intrauterine device occupies the uterus rather than simply covering the cervix, while an implant is placed under the skin and works through hormonal action. The cervical location and possible addition of spermicide together identify the intended group of contraceptive devices.
114. If a diaphragm remains correctly positioned over the cervix but the accompanying spermicide is omitted, the most reasonable prediction is that:
ⓐ. the diaphragm will begin releasing copper ions
ⓑ. ovulation will be permanently suppressed
ⓒ. the device will shift automatically into the uterine cavity
ⓓ. the physical barrier remains, but the additional sperm-killing contribution is lost
Correct Answer: the physical barrier remains, but the additional sperm-killing contribution is lost
Explanation: A diaphragm acts mainly as a physical barrier covering the cervix so that sperm entry is impeded. When a spermicidal cream, jelly or foam is used with it, a second contraceptive contribution is added: sperm that encounter the preparation are chemically impaired or killed. Removing the spermicide does not convert the diaphragm into another contraceptive class and does not cause it to release copper or hormones. If its placement remains correct, the physical barrier function is still present. What is specifically lost is the supplementary action supplied by the spermicide. This changed-condition reasoning shows why combined barrier-plus-spermicide use can improve contraceptive efficiency without changing the anatomical placement or basic identity of the diaphragm. Condoms form a physical barrier to semen entry and also reduce STI transmission risk, while cervical barriers mainly cover the cervix to impede sperm passage.
115. Consider the following statements about diaphragms, cervical caps and vaults.
I. They are female barrier contraceptives.
II. They cover the cervix and block sperm entry.
III. They may be used with spermicidal creams, jellies or foams.
IV. They are classified as disposable condoms because all barrier devices are single-use.
ⓐ. I, II and III only
ⓑ. I and IV only
ⓒ. II, III and IV only
ⓓ. I, II, III and IV
Correct Answer: I, II and III only
Explanation: Diaphragms, cervical caps and vaults belong to the female barrier group. Their position over the cervix creates a physical obstruction that limits sperm entry, and spermicidal creams, jellies or foams may be added to improve contraceptive efficiency. Statement IV is incorrect because these devices are described as reusable and should not be collapsed into the same practical category as disposable condoms. The shared term barrier refers to the general contraceptive principle of physically obstructing sperm movement, but different barrier devices can differ in placement, reuse and additional agents used with them. Statements I, II and III preserve both the common mechanism and the distinctive characteristics of these cervical barriers. Diaphragms, cervical caps and vaults are reusable female barriers that may be combined with spermicidal creams, jellies or foams.
116. Pair each feature of intrauterine contraception with the corresponding description. A Column II entry is used once.
| Column I | Column II |
| P. Final location | 1. Uterine cavity |
| Q. Route of insertion | 2. Through the vagina |
| R. Person performing insertion | 3. Doctor or expert nurse |
| S. Method category | 4. Intrauterine device |
ⓐ. P-2, Q-1, R-4, S-3
ⓑ. P-3, Q-4, R-1, S-2
ⓒ. P-4, Q-3, R-2, S-1
ⓓ. P-1, Q-2, R-3, S-4
Correct Answer: P-1, Q-2, R-3, S-4
Explanation: An intrauterine device is defined partly by its final anatomical location. It is placed within the uterus rather than on the penis, over the cervix or under the skin. The insertion occurs through the vagina and is performed by a trained professional such as a doctor or expert nurse. These features distinguish IUD use from self-applied barrier methods and from subcutaneous hormonal implants. The matching task connects location, route, personnel and category as parts of one coherent procedure. Correct classification requires following the device from its insertion route to its final position rather than assuming that any contraceptive placed through the female reproductive tract is simply a vaginal barrier. IUDs are professionally placed within the uterine cavity and share increased sperm phagocytosis as a general contraceptive effect.
117. One woman wants a long-term reversible contraceptive. A device is introduced through the vagina by an expert nurse and positioned within the uterine cavity. This contraceptive is:
ⓐ. a cervical cap
ⓑ. an intrauterine device
ⓒ. a female condom
ⓓ. a subcutaneous implant
Correct Answer: an intrauterine device
Explanation: The decisive clues are the insertion route, the trained person performing the procedure and the final location. A device passed through the vagina and positioned inside the uterine cavity by a doctor or expert nurse is an intrauterine device. A cervical cap remains at the cervix, a female condom acts as a barrier within the female tract during intercourse, and a subcutaneous implant is placed beneath the skin rather than inside the uterus. The case is solved by anatomical routing rather than by the general fact that all four options can be used for contraception. IUDs are distinguished specifically by professional placement into the uterus, which also prepares the basis for understanding their uterine mechanisms of action.
118. If a contraceptive that should lie inside the uterine cavity is instead placed beneath the skin, the method can no longer be classified as an IUD because:
ⓐ. uterine placement is required only for male contraceptives
ⓑ. every subcutaneous contraceptive must be a barrier method
ⓒ. intrauterine classification depends on final placement within the uterus
ⓓ. location has no relationship to contraceptive classification
Correct Answer: intrauterine classification depends on final placement within the uterus
Explanation: The term intrauterine identifies the anatomical location that defines the device category. IUDs are professionally placed within the uterine cavity and share increased sperm phagocytosis as a general contraceptive effect. An IUD is placed within the uterus after insertion through the vagina by trained personnel. A contraceptive placed beneath the skin belongs to a different route and method category, even if it also prevents pregnancy and may contain hormones. The described situation changes only the final location, and that change is sufficient to alter classification since site is part of the identity of an intrauterine device. This illustrates why contraceptives should not be grouped solely according to their shared purpose. Location, mode of administration and mechanism are important distinguishing features, and movement from the uterine cavity to a subcutaneous site changes the method category.
119. Assertion: Placement of an intrauterine device generally requires a trained medical professional.
Reason: Copper-releasing IUDs can reduce sperm motility and fertilising capacity.
ⓐ. Both Assertion and Reason are true, and Reason correctly explains Assertion
ⓑ. Both Assertion and Reason are true, but Reason does not explain Assertion
ⓒ. Assertion is true, but Reason is false
ⓓ. Assertion is false, but Reason is true
Correct Answer: Both Assertion and Reason are true, but Reason does not explain Assertion
Explanation: Both statements are true, but they address different features of intrauterine contraception. IUDs are inserted through the vagina and positioned within the uterine cavity by a doctor or expert nurse, so correct placement requires trained professional care. Copper-releasing IUDs have an additional contraceptive action: released copper ions suppress sperm motility and fertilising capacity, alongside the general IUD-associated increase in sperm phagocytosis. That copper effect does not explain why insertion requires a trained professional. The Assertion concerns the procedure and expertise needed for placement, whereas the Reason concerns the biological mechanism of one IUD class after placement. Separating insertion requirements from contraceptive mechanisms makes the logical relationship clear. The professional-placement requirement applies to the device as an intrauterine intervention, not specifically to copper release.
120. Lippes loop belongs to which IUD class?
ⓐ. copper-releasing IUD
ⓑ. hormone-releasing IUD
ⓒ. non-medicated IUD
ⓓ. subcutaneous hormonal implant
Correct Answer: non-medicated IUD
Explanation: Lippes loop is the representative non-medicated intrauterine device in the stated IUD classification. It is distinguished from copper-releasing devices such as CuT, Cu7 and Multiload 375 and from hormone-releasing devices such as Progestasert and LNG-20. Classification is important because different IUD classes share certain general uterine effects but may also add class-specific mechanisms. The correct answer identifies more than the fact that Lippes loop is an IUD; it places the device within the appropriate IUD subgroup. Keeping these categories separate becomes essential when later comparing copper-mediated effects on sperm with hormone-mediated changes in the uterus and cervix.
