1. Which of the following is a function of the placenta?

• A. The placenta secretes insulin.
• B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
• C. The placenta provides immunological protection to the fetus.
• D. The placenta stores fat-soluble vitamins for the fetus.

Correct answer: B

Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.

2. 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.

3. Which hormone is primarily responsible for the development of female secondary sexual characteristics?

• A. Progesterone
• B. Testosterone
• C. Estrogen
• D. Oxytocin

Correct answer: C

Rationale: Estrogen is primarily responsible for the development of female secondary sexual characteristics. Progesterone, while important in the menstrual cycle and pregnancy, is not primarily responsible for secondary sexual characteristics. Testosterone is the primary male sex hormone. Oxytocin is involved in labor, lactation, and social bonding, but not in the development of female secondary sexual characteristics.

4. Which family planning method was alternatively provided by the family life movement?

• A. Use of condom
• B. Use of spermicides
• C. Use of natural family planning
• D. Use of hormonal pills

Correct answer: C

Rationale: The family life movement promoted natural family planning as an alternative method. Natural family planning involves tracking a woman's menstrual cycle to determine the fertile period, making it distinct from the other options provided. Condoms (Choice A) and spermicides (Choice B) are barrier methods, while hormonal pills (Choice D) involve the use of synthetic hormones to prevent pregnancy. Therefore, the correct answer is the use of natural family planning.

5. 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.
