Correct Answer: B

Rationale: The correct answer is B because pallor in an extremity after a fracture could indicate compromised circulation, making it a priority for assessment. Choice A is not the priority as hypoactive bowel sounds in a client 1 hr postoperative, while concerning, do not indicate a life-threatening condition. Choice C, a client who had a cardiac catheterization 3 hr ago and has 3+ pedal pulses, indicates good perfusion and does not require immediate attention. Choice D, a client with an elevated AST level following the administration of azithromycin, may require further assessment but is not as urgent as the client with potential compromised circulation in choice B.

Correct Answer: C

Rationale: Increased urine output is a positive sign that the IV fluids are effectively treating dehydration. Tachycardia (choice A) and hypotension (choice B) are signs of dehydration and would not be considered positive responses to therapy. Diarrhea (choice D) can worsen dehydration and is not a positive response to IV fluid therapy.

Correct Answer: A

Rationale: The correct nursing priority for a patient experiencing an asthma exacerbation is to administer a bronchodilator. Bronchodilators help in relieving bronchoconstriction and improving breathing. While encouraging deep breathing, providing oxygen therapy, and monitoring oxygen saturation are essential aspects of managing asthma exacerbation, the priority is to administer a bronchodilator to address the acute bronchoconstriction.

Correct Answer: A

Rationale: The correct answer is A: Maintain sterility during dressing changes. It is crucial to maintain sterility during dressing changes for patients with central venous catheters to prevent infections. Changing the dressing weekly (Choice B) is not frequent enough to prevent infections effectively. Monitoring blood pressure and fluid balance (Choice C) is important for overall patient care but not specific to central venous catheter management. While monitoring the catheter site for infection (Choice D) is important, the key consideration is to prevent infections through proper sterile techniques during dressing changes.

Correct Answer: A

Rationale: The correct procedure for taking a telephone order from a provider is to state the patient's name, drug, dose, route, frequency, and then read back the order to ensure accuracy. This process helps in preventing errors and ensures that all relevant information is correctly documented. Choice B is incorrect because having a witness listen to the order is not a standard practice and may not guarantee accuracy. Choice C is incorrect as verifying the order within 12 hours may lead to delays in patient care. Choice D is incorrect because waiting for the provider to verify the order during the next in-person visit could result in a significant delay in administering necessary medication.
