1. Which technique is used to detect HIV/AIDS?

A. Northern blot and ELISA
B. Immunoblot and ELISA
C. Western blot and ELISA
D. Southern blot and ELISA

Correct answer: C

Rationale: The correct answer is C: Western blot and ELISA. Western blot and ELISA are commonly used techniques in the detection of HIV/AIDS. Western blot is used to confirm the presence of HIV antibodies in a patient's blood after an initial positive ELISA test. Northern blotting is a technique used for RNA analysis, not for detecting HIV/AIDS (Choice A). Immunoblotting is another term for Western blotting, so Choice B is incorrect. Southern blotting is used for DNA analysis, not for detecting HIV/AIDS (Choice D).

2. During a vaginal examination, which of the following statements is true?

A. Cervical scrapes cytology can be taken in the same setting.
B. Preferably done after bimanual examination.
C. The cervix is best visualized with the Crisco's type of spectrum.
D. During pregnancy, the cervix feels firm like the tip of the nose.

Correct answer: C

Rationale: The correct answer is C. The cervix is best visualized with the Cusco's type of spectrum. This statement is true and important during a vaginal examination. Choice A is incorrect because cervical cytology scrapes can be taken during the same setting as a vaginal examination, not necessarily prior to it. Choice B is incorrect as it states 'after' bimanual examination, which is not the typical sequence. Choice D is incorrect because during pregnancy, the cervix feels soft rather than firm like the tip of the nose.

3. Through which arteries does the blood supply to the external genitalia primarily occur?

A. Femoral arteries
B. Inguinal arteries
C. Pudendal arteries
D. Internal iliac arteries

Correct answer: C

Rationale: The correct answer is C: Pudendal arteries. The pudendal arteries are responsible for supplying blood to the external genitalia. These arteries specifically provide blood flow to the perineum, including the external genitalia. Choice A, Femoral arteries, are not primarily responsible for supplying blood to the external genitalia. Choice B, Inguinal arteries, do not supply blood directly to the external genitalia. Choice D, Internal iliac arteries, are not the main suppliers of blood to the external genitalia.

4. Expanded access to family planning through non-public delivery systems is facilitated by all of the following EXCEPT:

A. By using the private sector and social marketing
B. Community-based programs
C. Information, Education, and Communication
D. Key persons in the community

Correct answer: D

Rationale: Expanded access to family planning through non-public delivery systems involves utilizing various strategies to reach more people. Options A, B, and C are all effective methods for expanding access to family planning services. The involvement of key persons in the community is not a typical approach for non-public delivery systems. Key persons in the community may have influence but may not be directly involved in the delivery of family planning services, making option D the correct answer.

5. What is the measurement of the breast areola?

A. 3.5cm
B. 2.5cm
C. 4.5cm
D. 1.5cm

Correct answer: B

Rationale: The correct answer is 2.5 cm. The average measurement of the areola is approximately 2.5 cm. Choices A, C, and D are incorrect as they do not align with the typical measurement of the breast areola.
