When teaching a patient about self-administration of insulin, what is the most important instruction to provide?

Correct Answer: A

Rationale: The most important instruction to provide when teaching a patient about self-administration of insulin is to rotate injection sites to prevent tissue damage. Rotating injection sites helps prevent lipodystrophy (tissue damage) and ensures proper insulin absorption. Option B is incorrect because the angle of insulin injection varies depending on the patient's body composition. Injecting at a 90-degree angle is not always necessary. Option C is not the most crucial instruction; while storing insulin in the refrigerator is important, it is not the priority when teaching self-administration. Option D is also important for maintaining consistency but is not as critical as rotating injection sites to prevent tissue damage.

Correct Answer: C

Rationale: The correct answer is to administer the transfusion at a slow rate for the first 15 minutes. This practice is crucial as it helps in detecting any adverse reactions early on. Checking the patient's vital signs every 30 minutes (choice B) is important but not as essential as ensuring a slow rate at the beginning. Administering blood within 4 hours (choice A) is a standard practice but not directly related to the initial administration. Documenting the transfusion immediately (choice D) is necessary but does not directly impact the safety of the initial administration.

Correct Answer: B

Rationale: When a nurse observes a colleague behaving strangely, the best course of action is to report the behavior to the supervisor. Unusual behavior by a healthcare professional could compromise patient safety and should be addressed promptly. Ignoring the behavior (Choice A) could potentially lead to negative outcomes for patients. Asking the colleague directly (Choice C) may not be appropriate if the behavior poses a risk. Discussing the behavior with other colleagues (Choice D) may not directly address the issue and could lead to gossip rather than a resolution.

Correct Answer: A

Rationale: Correct answer: When a patient with a left arm fracture reports severe pain unrelieved by medication, the nurse should assess for compartment syndrome. Compartment syndrome is a condition where increased pressure within a muscle compartment compromises circulation and can lead to tissue damage. It is a surgical emergency that requires immediate intervention. Choice B is incorrect because simply increasing pain medication without identifying the cause of the unrelieved pain may mask symptoms of a serious issue like compartment syndrome. Choice C is incorrect as surgery would only be necessary if compartment syndrome is confirmed. Choice D is incorrect as administering a sedative does not address the underlying issue of unrelieved pain and may delay appropriate treatment.

Correct Answer: B

Rationale: The most appropriate action when finding incomplete documentation is to notify the nurse manager of the issue. This ensures that accurate records are maintained and the situation can be addressed properly. Completing the missing documentation on behalf of someone else may lead to inaccuracies, asking the nurse to complete it may not guarantee timely correction, and confronting the nurse could create a confrontational situation that is not conducive to effective teamwork.
