Correct Answer: A

Rationale: The correct answer is 'Ventrogluteal.' The ventrogluteal site is recommended for intramuscular injections in adults because it is free of major blood vessels and nerves, reducing the risk of injury or complications. Choice B, 'Dorsogluteal,' is not recommended due to the proximity of the sciatic nerve and major blood vessels. Choices C and D, 'Vastus lateralis' and 'Rectus femoris,' are sites commonly used for intramuscular injections but are more suitable for pediatric or specific population groups, not typically for adults.

Correct Answer: D

Rationale: When caring for a client with a C. difficile infection, it is essential to isolate them in a private room to prevent the spread of spores through contact with surfaces. Placing the client in a negative pressure room (Choice A) is not necessary for C. difficile. Using alcohol-based hand rub (Choice B) and wearing a face shield (Choice C) are important infection control measures but are not specific to the isolation requirements for C. difficile.

Correct Answer: A

Rationale: Using a designated stethoscope for the toddler is crucial to reduce the risk of spreading RSV to other patients. Choice B is incorrect because N95 respirator masks are not specifically indicated for RSV. Choice C is unnecessary as RSV does not require isolation in a negative pressure room. Choice D is incorrect because the gown should be removed after leaving the room to prevent transmission of pathogens to other areas.

Correct Answer: B

Rationale: The nurse should question the prescription to apply heat to the affected extremity for 45 minutes. Heat should not be applied in the first 48 hours after an acute injury, as it can increase swelling. Cold therapy is more appropriate initially. Choices A, C, and D are appropriate actions in the care of a client with a sprained ankle. Elevating the affected extremity helps reduce swelling, wrapping it with a compression dressing provides support, and assessing sensation, movement, and pulse every 4 hours is important to monitor for complications.

Correct Answer: A

Rationale: The correct answer is A: Diaphoresis. Diaphoresis, which refers to excessive sweating, is a classic symptom of hypoglycemia. Instructing the client to monitor for diaphoresis is crucial as it can help them recognize and address hypoglycemic events promptly. Polyuria (excessive urination), abdominal pain, and thirst are not typical signs of hypoglycemia. Polyuria is more commonly associated with conditions like diabetes mellitus, while abdominal pain and thirst are not specific indicators of low blood sugar levels.
