Correct Answer: C

Rationale: In this scenario, when a field medical element is not operational, training is essential to prepare for mobilization. Proficiency in MOS/ASI (Military Occupational Specialty/Area of Specialization) is crucial, along with proficiency in common soldier tasks. Common soldier tasks encompass fundamental skills and knowledge that are essential for operational readiness and mobilization. Options A, B, and D are not as directly related to individual readiness for mobilization in this context.

Correct Answer: D

Rationale: Assisting the client to sit in a chair is an essential nursing intervention postoperatively as it helps promote circulation, prevent complications like blood clots, and aids in the recovery process. Changing the infusion rate of intravenous fluid (Choice A) requires a physician's order and is not an independent nursing intervention. Encouraging the client to discuss feelings (Choice B) is important for emotional support but not as crucial as physical care immediately postoperatively. Administering opioid narcotic medications (Choice C) for pain management should be based on a prescribed schedule and assessment rather than being an independent nursing action.

Correct Answer: C

Rationale: Patients taking anticoagulants should be cautious about consuming high-vitamin K foods. Vitamin K can interfere with the effectiveness of anticoagulants by affecting blood clotting. Choices A, B, and D are incorrect because they do not directly interact with the action of anticoagulants.

Correct Answer: B

Rationale: The correct answer is B: Gastritis may cause bleeding. In patients with hiatal hernia, gastritis can lead to gastrointestinal bleeding, resulting in anemia due to blood loss. Choice A is incorrect because hiatal hernia does not directly affect iron absorption. Choice C is incorrect as iron stores turning over more quickly is not a typical reason for anemia in hiatal hernia patients. Choice D is incorrect as an aversion to iron-rich foods does not directly cause anemia in this context.

Correct Answer: B

Rationale: Weighing the client daily at the same time each day is the most accurate method for monitoring fluid balance. Changes in body weight can reflect fluid retention or loss. Measuring and recording fluid intake and output (Choice A) is important but may not provide immediate changes in fluid status. Assessing vital signs (Choice C) can offer some information but may not be as specific to fluid status as daily weighing. Checking the client's lungs for crackles (Choice D) is more related to assessing respiratory status rather than direct fluid monitoring.
