Correct Answer: A

Rationale: Administering insulin is the priority intervention for a patient admitted with high blood sugar levels because it helps lower the blood sugar levels effectively and rapidly. Insulin is a crucial medication for managing hyperglycemia in diabetes. Encouraging exercise (choice B) can be beneficial in the long term for managing blood sugar levels but is not the most immediate priority. While staying hydrated (choice C) is important, it is not the priority intervention when dealing with high blood sugar levels. Providing a low-sugar diet (choice D) is essential for long-term diabetes management but is not the immediate action needed to address high blood sugar levels in an admitted patient.

Correct Answer: B

Rationale: Checking the patient's weight daily is the most reliable indicator of fluid status because weight changes can directly reflect fluid retention or loss. Monitoring vital signs (Choice A) can provide some information but is not as specific as weight changes. Measuring intake and output (Choice C) is crucial but may not always accurately reflect fluid balance. Monitoring urine color (Choice D) can give some insights into hydration levels, but it is not as reliable as daily weight checks for assessing overall fluid status.

Correct Answer: D

Rationale: During a potential bioterrorism attack, the priority for the nurse is to manage all patients using standard precautions. This approach ensures the safety of both patients and healthcare providers by preventing the spread of potential bioterrorism-related illnesses. Option A is incorrect because managing patient care and safety through standard precautions takes precedence. Option B is incorrect as patient transport should also be done while adhering to infection control measures. Option C is incorrect as monitoring for specific symptoms is important but not the priority when all patients need to be managed with standard precautions.

Correct Answer: C

Rationale: The correct first action for the nurse to take when a patient has difficulty ambulating after surgery is to call for assistance with ambulation. This is essential to ensure the safety of the patient and prevent any potential falls or injuries. Encouraging deep breathing exercises (Choice A) may be beneficial but should not be the first priority when the patient is having difficulty walking. Assisting the patient in ambulating a short distance (Choice B) may put both the patient and the nurse at risk if the patient is struggling. Assessing the patient's pain level before ambulation (Choice D) is important but should come after ensuring that the patient can safely ambulate with assistance.

Correct Answer: B

Rationale: The nurse's priority action should be to withhold the medication until the trough level is obtained. This is crucial to ensure accurate dosing based on the patient's levels. Administering the medication before the peak level is obtained (choice A) can lead to incorrect dosing. Administering the medication based on the previous trough level (choice C) may not reflect the current levels accurately. Ensuring that the medication is administered within 2 hours of the peak level (choice D) is not necessary for obtaining accurate peak and trough levels.
