1. Amniocentesis deals with patterns of ______ in the amniotic fluid.

• A. Fingers
• B. DNA
• C. Chromosomes
• D. Proteins

Correct answer: C

Rationale: Amniocentesis is a prenatal test that involves examining chromosomes in the amniotic fluid to detect genetic abnormalities. Therefore, the correct answer is 'Chromosomes.' The other choices, such as 'Fingers,' 'DNA,' and 'Proteins,' do not accurately represent what is analyzed during an amniocentesis procedure and are unrelated to the genetic information obtained through this test.

2. At what point is a fetus considered viable?

• A. 26 weeks
• B. 28 weeks
• C. 37 weeks
• D. 12 weeks

Correct answer: C

Rationale: A fetus is considered viable after 37 weeks of gestation. At this stage, the fetus has a higher chance of surviving outside the womb with medical support. Choice A (26 weeks), Choice B (28 weeks), and Choice D (12 weeks) are incorrect because a fetus is not typically considered viable at those earlier gestational ages.

3. At 3-4 weeks of pregnancy, the breast changes include:

• A. Darkening of the nipple.
• B. Prickling, tingling sensation.
• C. Breast becomes tender.
• D. Colostrum can be expressed.

Correct answer: C

Rationale: At 3-4 weeks of pregnancy, breast changes commonly involve tenderness due to hormonal fluctuations. Darkening of the nipple (Choice A) typically occurs later in pregnancy. Prickling, tingling sensations (Choice B) are more associated with early pregnancy due to increased blood flow to the breast area. Colostrum production (Choice D) usually begins later in pregnancy, closer to the end of the third trimester.

4. What is another name for the breast?

• A. Sebaceous glands
• B. Racemose glands
• C. Mammary glands
• D. Axillary glands

Correct answer: C

Rationale: The correct answer is C: Mammary glands. The mammary glands are the specific glands in the breast responsible for producing milk. Sebaceous glands (choice A) are oil-producing glands in the skin, racemose glands (choice B) are not a recognized term, and axillary glands (choice D) refer to glands found in the armpit region, not the breast.

5. Herpes simplex type 2 (HSV-2) does not cause cold sores of the lips:

• A. True.
• B. False.
• C. Depends on the person.
• D. Not enough information.

Correct answer: B

Rationale: Herpes simplex type 2 (HSV-2) typically causes genital herpes, not cold sores on the lips. Cold sores on the lips are commonly caused by herpes simplex type 1 (HSV-1). Therefore, the statement that HSV-2 causes cold sores of the lips is incorrect. Choice B, 'False,' is the correct answer. Choice A is incorrect because HSV-2 does not cause cold sores on the lips. Choice C, 'Depends on the person,' is incorrect as the cause of cold sores is predominantly linked to HSV-1. Choice D, 'Not enough information,' is also incorrect as this information is well-established in medical knowledge.
