Correct Answer: D

Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

Correct Answer: C

Rationale: In a triage situation, an asymmetrical thorax suggests a potentially life-threatening condition such as a pneumothorax or hemothorax, requiring immediate attention. This client should be tagged as emergent. Periorbital ecchymosis and deep-partial thickness burns, while concerning, may not indicate an immediate life-threatening situation. An open fracture of the femur, although serious, can be prioritized after addressing emergent cases.

Correct Answer: B

Rationale: When dealing with a client exhibiting disruptive behavior like yelling obscenities, involving a family member can provide emotional support and help in de-escalating the situation. Keeping the client isolated in their room (Choice A) may lead to further agitation. Placing the client in a wheelchair (Choice C) or administering a sedative (Choice D) should not be the first interventions for managing behavioral issues.

Correct Answer: B

Rationale: The correct answer is B: 'To assess and improve quality of care.' Healthcare audits are conducted to evaluate the quality and efficiency of healthcare services provided. Choice A, 'To increase paperwork,' is incorrect as audits aim to streamline processes and reduce unnecessary paperwork. Choice C, 'To reduce patient satisfaction,' is incorrect as audits are meant to identify areas for improvement to enhance patient satisfaction. Choice D, 'To limit healthcare services,' is also incorrect as audits help in optimizing healthcare services rather than limiting them.

Correct Answer: D

Rationale: Orthostatic hypotension and flat neck veins are classic manifestations of fluid volume deficit. When the body loses fluid, blood volume decreases, leading to decreased venous return to the heart, resulting in orthostatic hypotension and flat neck veins. Choices A, B, and C are more indicative of other conditions such as dehydration, respiratory issues, or compensatory mechanisms in response to hypovolemia, respectively.
