Correct Answer: A

Rationale: This statement indicates a need for additional instruction because while site rotation is essential, it's important to rotate sites within the same anatomical region (such as staying within the abdomen for several injections before moving to a different region). Rotating too frequently between different regions can cause inconsistent insulin absorption, which can affect blood sugar control.

Correct Answer: C

Rationale: The correct answer is C: 'To control the spread of infections within the healthcare setting.' The primary goal of infection control practices is to prevent the transmission and spread of infections among patients, healthcare workers, and visitors. Choice A is incorrect because while infection control practices may indirectly contribute to shorter hospital stays by preventing additional complications, reducing the length of hospital stays is not their primary goal. Choice B is incorrect as ensuring patient safety and preventing infections are important outcomes of infection control practices but not the primary goal. Choice D is incorrect because compliance with healthcare regulations is a requirement that supports the implementation of infection control practices but is not the primary goal of these practices.

Correct Answer: B

Rationale: The correct answer is B: Increase the client's intake of carbohydrates. Adequate nutrition, including carbohydrates, is essential for tissue repair and preventing skin breakdown. Placing the client in high-Fowler's position (choice A) may help with respiratory function but does not directly prevent skin breakdown. Massaging areas of darker skin (choice C) can cause further damage to the skin. Using a trapeze bar (choice D) may assist with changing positions but does not directly address skin breakdown prevention.

Correct Answer: C

Rationale: Values are learned through continuous reinforcement, where behaviors are positively reinforced to instill values. Reading books (choice A) may expose individuals to different perspectives but doesn't necessarily lead to internalizing values. Formal degrees (choice B) provide education but may not directly teach values. Meeting diverse individuals (choice D) can broaden perspectives but doesn't guarantee learning specific values through reinforcement.

Correct Answer: D

Rationale: Chest pressure while walking may indicate heart-related issues such as angina or a heart attack. Rosiglitazone (Avandia) has been associated with increased risks of cardiovascular events like heart failure. Given these risks, chest pressure is an urgent symptom that must be reported immediately to prevent potentially life-threatening complications.
