1. DiGeorge syndrome is a primary immune deficiency caused by:

Correct answer: B

Rationale: DiGeorge syndrome is caused by a congenital lack of thymic tissue, which plays a crucial role in T cell development and maturation, leading to immune deficiency. Choice A is incorrect because DiGeorge syndrome primarily affects T cells, not B cells. Choice C is incorrect as it is too broad and not specific to the thymus. Choice D is incorrect as selective IgG deficiency is a different condition unrelated to DiGeorge syndrome.

2. A patient is receiving finasteride (Proscar) for the treatment of benign prostatic hyperplasia. Which of the following is an expected outcome of the medication?

Correct answer: B

Rationale: The correct answer is B. Finasteride (Proscar) is used in the treatment of benign prostatic hyperplasia to improve urinary flow and decrease symptoms of urinary retention by reducing the size of the prostate gland. Choice A is incorrect because although finasteride may reduce the size of the prostate gland, the expected outcome relevant to the patient's symptoms is improved urinary flow rather than a specific change in gland size. Choice C is incorrect because finasteride actually decreases the production of prostate-specific antigen (PSA) due to its mechanism of action. Choice D is incorrect because although improved urinary flow may lead to a reduction in nocturnal awakenings, the main expected outcome of finasteride treatment is related to urinary symptoms.

3. An imbalance of which of the following hormones could lead to increased calcium levels in the blood?

Correct answer: A

Rationale: The correct answer is Parathyroid hormone (Choice A). Parathyroid hormone plays a key role in regulating calcium levels in the blood. When there is an imbalance in parathyroid hormone secretion, it can lead to increased calcium levels in the blood. Antidiuretic hormone (Choice B) is involved in regulating water balance, not calcium levels. Calcitonin (Choice C) helps lower blood calcium levels and is unlikely to cause an increase. Melatonin (Choice D) regulates sleep-wake cycles and does not have a direct effect on calcium levels in the blood.

4. Cellular swelling is:

Correct answer: B

Rationale: Cellular swelling is indeed evident early in all types of cellular injury. This occurs due to the influx of water into the cell, leading to swelling. Choice A is incorrect because cellular swelling is reversible if the injury is not severe. Choice C is incorrect because cellular swelling is not manifested by decreased intracellular sodium; in fact, it is associated with increased intracellular sodium due to water influx. Choice D is incorrect as option B is the correct statement.

5. A patient with a complex medical history is considering the use of oral contraceptives. The nurse should be aware that many antibiotics and antiseizure medications cause what effect when combined with oral contraceptives?

Correct answer: A

Rationale: The correct answer is A: Increased risk of pregnancy. Certain antibiotics and anticonvulsants can decrease the effectiveness of oral contraceptives by inducing liver enzymes that metabolize the hormones more quickly. This interaction can lead to a decreased contraceptive effect, thereby increasing the risk of pregnancy. Choices B, C, and D are incorrect as they do not directly relate to the effect of antibiotics and antiseizure medications on oral contraceptives.
