1. What is one characteristic of human immunodeficiency virus (HIV)?

A. The presence of circulating antibodies that neutralize HIV is evidence of exposure to HIV.
B. HIV replication occurs intracellularly.
C. HIV integrates its genetic material into the host cell's DNA.
D. DNA replication is irrelevant to HIV.

Correct answer: C

Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.

2. Which hormone is responsible for amenorrhea in the pregnant woman?

A. Progesterone
B. Estrogen
C. Follicle-stimulating hormone (FSH)
D. Human chorionic gonadotropin (hCG)

Correct answer: A

Rationale: Correct! Progesterone is the hormone responsible for amenorrhea in pregnant women. Progesterone plays a crucial role in maintaining the uterine lining for implantation and supporting early pregnancy. High levels of progesterone during pregnancy suppress the normal menstrual cycle, leading to amenorrhea. Estrogen, FSH, and hCG do not directly cause amenorrhea in pregnant women. Estrogen is involved in the development of female secondary sexual characteristics, FSH is involved in the growth and maturation of ovarian follicles, and hCG is produced by the placenta to support the production of progesterone during pregnancy.

3. A client newly diagnosed with Diabetes Mellitus needs education. Which of the following statements should the nurse include in this education?

A. "You can eat anything you want, but avoid foods with sugar."?
B. "You need to lose weight, so your diet must be controlled."?
C. "You need a diet and exercise program."?
D. "You must reduce salt, fat, and sugar intake in your diet."?

Correct answer: C

Rationale: A client newly diagnosed with Diabetes Mellitus requires education on managing their condition. Choice C is the correct answer because it emphasizes the importance of a comprehensive approach involving both diet and exercise. This holistic approach is crucial in managing blood sugar levels and overall health for individuals with diabetes. Choice A is incorrect as it provides misleading information by suggesting that the client can eat anything as long as it doesn't contain sugar, which is not accurate for diabetes management. Choice B is not the best option as it focuses solely on weight loss rather than addressing the holistic needs of a diabetic individual. Choice D is incorrect as it suggests eliminating all salt, fat, and sugar, which is an extreme approach and not a realistic or balanced way to manage diabetes.

4. One of the major functions of the kidneys in maintaining normal fluid balance is:

A. the manufacture of antidiuretic hormone.
B. the regulation of calcium and phosphate balance.
C. the regulation of the pH of the extracellular fluid.
D. the control of aldosterone levels.

Correct answer: C

Rationale: The correct answer is 'the regulation of the pH of the extracellular fluid.' The kidneys play a crucial role in maintaining normal fluid balance by regulating extracellular fluid and osmolarity through selective retention and excretion of fluids. Additionally, they regulate the pH of the extracellular fluid by retaining hydrogen ions and excreting metabolic wastes and toxic substances. Choice A is incorrect because antidiuretic hormone (ADH) is manufactured by the pituitary gland, not the kidneys. Choice B is incorrect as the regulation of calcium and phosphate balance is primarily controlled by the parathyroid gland. Choice D is incorrect as aldosterone levels are controlled by the adrenal glands, not the kidneys.

5. The client is undergoing an induction for fetal demise at 34 weeks. Immediately after delivery, the mother asks to see the infant. What is the nurse's best response?

A. Bring the swaddled fetus to the mother
B. Explain that the cause of death must be determined before she can see the baby
C. Ask her if she is sure she wants to see the baby
D. Tell her it would be better to wait until she is in her room before she sees the baby

Correct answer: A

Rationale: The nurse should bring the swaddled fetus to the mother as the best response. Allowing the mother to see the infant immediately after delivery is crucial for her grieving process. It provides her with the opportunity to bond, say goodbye, and start the grieving process. Choice B is incorrect because delaying the mother's request to see the baby can hinder her grieving process and prolong her suffering. Choice C is inappropriate as it questions the mother's decision at a sensitive time, potentially causing distress. Choice D is also not the best response as it suggests waiting, which may not be in the mother's best interest at that moment, as she needs immediate support and closure.
