Correct Answer: A

Rationale: The correct answer is A: Pregnancy. During pregnancy, the need for iron increases significantly to support the growth of the fetus and to prevent maternal anemia. Iron is essential for the production of hemoglobin and for oxygen transport in the blood. In contrast, infants require iron for rapid growth and development, making choice B partially correct. Choice C (Old age) and choice D (Male reproductive years) are incorrect as the need for iron typically decreases in old age and remains relatively stable during male reproductive years.

Correct Answer: B

Rationale: The correct answer is B: Keep extremities at neutral position. This intervention promotes proper blood flow and reduces the risk of thrombophlebitis by preventing compression or restriction of blood vessels. Removing and reapplying elastic stockings (choice A) can disrupt circulation and increase the risk of thrombophlebitis. Changing the client's position (choice C) may not directly address hemostasis or thrombophlebitis. Using a flotation mattress (choice D) is not specifically focused on maintaining proper positioning of the extremities to promote circulation.

Correct Answer: A

Rationale: The correct answer is A (5 to 10 mcg/ml) because this range is typically considered therapeutic for phenytoin (Dilantin) for seizure control. Levels below 5 mcg/ml may be subtherapeutic, leading to inadequate seizure control. Levels above 10 mcg/ml can increase the risk of toxicity. Choices B, C, and D are incorrect because they are outside the optimal therapeutic range, leading to either ineffective treatment (B, C) or an increased risk of adverse effects (D). Monitoring drug levels helps ensure the medication's effectiveness while minimizing side effects.

Correct Answer: C

Rationale: The correct answer is C: Hematuria. Bacillus Calmette-Guerin (BCG) is a type of immunotherapy used to treat bladder cancer by stimulating the immune system to attack cancer cells. One common side effect of BCG instillations is hematuria, which is the presence of blood in the urine. This occurs because BCG irritates the bladder lining, leading to inflammation and bleeding. It is important for the nurse to educate the client about this potential side effect so they are aware and can report any excessive bleeding to their healthcare provider promptly. Other choices are incorrect: A: Renal calculi - BCG therapy is not known to cause renal calculi. B: Delayed ejaculation - BCG therapy is not associated with delayed ejaculation. D: Impotence - BCG therapy is not linked to impotence.

Correct Answer: B

Rationale: The correct answer is B because it encourages the patient to share any additional information they may have forgotten or overlooked, ensuring a thorough health history interview. Choice A is incorrect as it implies the interviewer is unprepared or disinterested. Choice C is inappropriate as it may make the patient feel guilty or inadequate. Choice D is incorrect as it does not address the possibility of gathering more relevant information from the patient.
