A client receiving morphine via patient-controlled analgesia (PCA) should have naloxone administered if their respiratory rate is below 10/min. What action should the nurse take?

Correct Answer: C

Rationale: The correct action for the nurse to take is to administer naloxone if the client's respiratory rate falls below 10/min. Naloxone is used to reverse opioid-induced respiratory depression, which is a life-threatening situation. Monitoring the client's blood pressure every 4 hours (Choice A) is not the priority in this scenario as respiratory depression requires immediate attention. Asking the client to rate their pain every 2 hours (Choice B) is important for pain management but addressing respiratory depression takes precedence. Evaluating the client's use of the PCA every 4 hours (Choice D) is a routine nursing intervention but does not directly address the urgent need to reverse respiratory depression in this case.

Correct Answer: B

Rationale: The correct answer is B. A heart rate of 68/min is lower than expected and should be reported as it may indicate digoxin toxicity. Choices A, C, and D are within normal limits for a client receiving furosemide for heart failure and do not require immediate reporting. Weight loss may be expected due to diuretic therapy, a potassium level of 3.8 mEq/L is within the normal range, and a urine output of 60 mL/hr indicates adequate renal perfusion.

Correct Answer: A

Rationale: The correct answer is A because clients taking warfarin should have their INR (International Normalized Ratio) checked regularly to monitor the medication's effectiveness and adjust the dose if needed. This monitoring helps to ensure the medication is working correctly and the client is within the therapeutic range. Choice B is incorrect because clients on warfarin should not avoid leafy green vegetables but should maintain a consistent intake. Leafy green vegetables contain vitamin K, which can affect warfarin, so it's important to maintain a consistent intake to keep INR stable. Choice C is incorrect as clients should not stop taking warfarin abruptly without consulting their healthcare provider as it can lead to serious health risks like blood clots. Choice D is incorrect because while taking warfarin, it is important to avoid unnecessary aspirin use due to an increased risk of bleeding. However, this statement does not indicate an understanding of the teaching about the need for regular INR monitoring.

Correct Answer: C

Rationale: The correct action for the nurse to take is to check the client's creatinine level before administering vancomycin. Vancomycin is known to be nephrotoxic, so assessing the client's renal function before administering the medication is crucial to prevent further kidney damage. Administering the medication over 15 minutes (Choice A) is not the priority in this scenario as renal function assessment takes precedence. Monitoring urine output (Choice B) is important for assessing renal function but checking creatinine level directly provides more accurate information. Assessing for allergies to antibiotics (Choice D) is also important but not as essential as checking the creatinine level due to the nephrotoxic nature of vancomycin.

Correct Answer: C

Rationale: The correct answer is C: 'You should rinse your mouth after using this medication.' When providing discharge teaching for a client prescribed albuterol, the nurse should include the instruction to rinse the mouth after each use. This is important to prevent dry mouth and oral infections. Choice A is incorrect as albuterol is usually taken during the day to manage symptoms, not at bedtime. Choice B is incorrect as palpitations are not a common side effect of albuterol. Choice D is incorrect as there is no specific requirement to avoid eating before taking albuterol.
