Correct Answer: B

Rationale: Drawing up insulin after warming the vial to room temperature indicates a need for further teaching, as insulin should be at room temperature for administration. Choice A is correct as rotating injection sites helps prevent lipodystrophy. Choice C is correct as pinching the skin helps ensure proper subcutaneous injection. Choice D is correct as injecting insulin at a 90-degree angle is the recommended technique for subcutaneous injections.

Correct Answer: B

Rationale: The correct answer is B, 'Allergic to shellfish.' An allergy to shellfish can indicate a sensitivity to iodine, which is used in the contrast dye for an IVP, posing a risk of an allergic reaction. Reflex incontinence (Choice A) is not directly related to the potential hazard of an IVP. Claustrophobia (Choice C) and hypertension (Choice D) are also not significant factors that indicate a potential hazard for an IVP.

Correct Answer: C

Rationale: The nurse's priority should be to eliminate safety hazards from the client's environment as it directly reduces the risk of falls. Addressing environmental hazards is an immediate and crucial step in preventing falls. While completing a fall-risk assessment is important to understand the client's risk factors, educating the client and family about fall risks is essential for prevention, and ensuring the use of assistive aids is crucial for safety, eliminating safety hazards takes precedence as it directly mitigates the risk of falls.

Correct Answer: C

Rationale: The most appropriate intervention for a client with amphetamine toxicity and sensory overload is to provide a private room and limit stimulation. This approach helps reduce external stimuli, which can exacerbate sensory overload, and creates a calming environment for the client. Encouraging visitors to distract the client may worsen sensory overload by adding more stimulation. Speaking softly, rather than at a higher volume, is more suitable to help maintain a calm environment. Therefore, the correct choice is to provide a private room and limit stimulation (option C) in this scenario.

Correct Answer: A

Rationale: To calculate the mL/hr rate for the infusion, divide the total volume (750 mL) by the total time (7 hours). 750 mL · 7 hours = 107 mL/hr. This means that the pump should be set to deliver approximately 107 mL/hr. Choice B (75 mL/hr) is incorrect because it does not reflect the correct calculation. Choice C (90 mL/hr) is incorrect as it does not align with the accurate calculation. Choice D (60 mL/hr) is incorrect as it does not match the correct mL/hr rate obtained through the calculation.
