1. How many autosomes does a human primary spermatocyte have?

A. 34
B. 44
C. 54
D. 33

Correct answer: B

Rationale: A human primary spermatocyte has 44 autosomes. Autosomes are chromosomes that are not involved in determining an individual's sex. In humans, there are a total of 46 chromosomes in a somatic cell, with 22 pairs of autosomes and one pair of sex chromosomes. Therefore, the correct answer is 44 autosomes, making choice B the correct answer. Choices A, C, and D are incorrect as they do not represent the accurate number of autosomes in a human primary spermatocyte.

2. What is the primary use of Bromocriptine?

A. Relieve constriction ring.
B. Manage post-partum hemorrhage.
C. Affect milk production.
D. Be used in pre-eclampsia.

Correct answer: C

Rationale: Bromocriptine is primarily used to affect milk production. It is a medication commonly prescribed to help suppress lactation, particularly in cases of postpartum breast engorgement or when stopping breastfeeding. Choices A, B, and D are incorrect as Bromocriptine is not indicated for relieving constriction ring, managing post-partum hemorrhage, or treating pre-eclampsia.

3. At 34-40 weeks of pregnancy, the breast changes include:

A. Nipples become prominent and mobile.
B. Colostrum can be expressed.
C. Breasts become tender.
D. Montgomery's tubercles are prominent.

Correct answer: D

Rationale: During the 34-40 weeks of pregnancy, Montgomery's tubercles become prominent. These are sebaceous glands on the areola, not the nipples. Choice A is incorrect as it describes the changes in nipples, not Montgomery's tubercles. Choice B is incorrect as colostrum production usually starts around the 16th week. Choice C is incorrect as breast tenderness is more common in early pregnancy due to hormonal changes.

4. When does missed abortion occur?

A. The fetus dies and is retained in utero with the placenta and membranes.
B. All products of conception are expelled with minimal bleeding.
C. The cervix remains closed, and the products of conception remain in the uterus.
D. The cervix remains closed, but there is heavy bleeding.

Correct answer: C

Rationale: Missed abortion occurs when the cervix is closed, and the products of conception remain in the uterus. Choice A describes a missed abortion, not choice C. Choice B describes a complete abortion. Choice D describes a threatened abortion, where the cervix remains closed but there is heavy bleeding.

5. What is the reasonable available distance from all patients to offer Primary Health Care (PHC) services?

A. Within a 20 Km radius
B. Within a 15 Km radius
C. Within a 12 Km radius
D. Within a 10 Km radius

Correct answer: A

Rationale: The correct answer is within a 20 Km radius. Primary Health Care services should be accessible within a 20 Km radius to ensure adequate coverage for all patients. This distance allows for a reasonable reach while ensuring that individuals can access essential healthcare services in a timely manner. Choices B, C, and D are incorrect as they offer distances that may limit accessibility and coverage, potentially leaving some patients without timely access to necessary healthcare.
