Correct Answer: D

Rationale: The correct answer is D: Effectively managing personnel. In a healthcare setting, managing personnel is crucial as it involves leading, motivating, and coordinating the healthcare team to ensure quality patient care. While tasks like preparing schedules, inspecting equipment, and maintaining records are important, managing personnel involves dealing with human factors, conflicts, and emotions, making it the most challenging skill for a practical nurse.

Correct Answer: B

Rationale: The correct answer is B: Gastritis may cause bleeding. In patients with hiatal hernia, gastritis can occur due to the reflux of stomach acid into the esophagus. This gastritis can lead to gastrointestinal bleeding, resulting in anemia. Choice A is incorrect because iron absorption is not necessarily reduced in hiatal hernia. Choice C is incorrect as iron stores turnover rate is not directly related to the development of anemia in this context. Choice D is incorrect as an aversion to iron-rich foods is not a common reason for anemia in patients with hiatal hernia.

Correct Answer: B

Rationale: The combat health support system in the field is primarily designed to project, sustain, and protect the health of soldiers during war and other operations. Choice A is incorrect as it focuses solely on evacuation and delaying return to duty, missing the broader scope of health support. Choice C is incorrect as it only mentions rearward evacuation and reassignment, which is not the sole purpose of the combat health support system. Choice D is also incorrect as it emphasizes far rear area care and delayed return to duty, neglecting the comprehensive nature of health support in combat situations.

Correct Answer: A

Rationale: The correct response is to assess the intravenous fluids for rate and volume. In this situation, the client is seeking guidance on fertility issues, not related to intravenous fluids, surgical dressing changes, medication levels, or meal monitoring. The nurse should provide supportive and empathetic guidance, suggesting further options like consulting fertility specialists or exploring additional treatments.

Correct Answer: C

Rationale: The correct answer is C. Smoking, especially in clients over 30, increases the risk of thromboembolic events, making oral contraceptives contraindicated. Choice A (More than 30 years of age) is not a direct contraindication for oral contraceptives. Choice B (Had two multiple pregnancies) is not a factor that contraindicates the use of oral contraceptives. Choice D (Has a history of borderline hypertension) is not a specific contraindication for oral contraceptives unless it is severe or uncontrolled hypertension.
