Nursing Elites

1. Which electrolyte imbalance is most concerning in a patient taking digoxin?

• A. Monitor potassium levels
• B. Monitor calcium levels
• C. Monitor sodium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

2. A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?

• A. Platelets 250,000/mm³
• B. aPTT 60 seconds
• C. Hemoglobin 15 g/dL
• D. INR 1.5

Correct answer: B

Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.

3. A nurse is teaching a client who has a new prescription for fluoxetine. Which of the following statements should the nurse include?

• A. "You should expect to feel an improvement in your symptoms within 1 week."
• B. "You may experience weight gain while taking this medication."
• C. "You should take this medication in the morning to prevent insomnia."
• D. "You should stop taking this medication if you experience dry mouth."

Correct answer: B

Rationale: The correct statement the nurse should include is that the client may experience weight gain while taking fluoxetine. Weight gain is a common side effect of fluoxetine, and patients should be informed about this potential issue. Stating that the client should expect improvement in symptoms within 1 week (Choice A) is incorrect as fluoxetine may take a few weeks to have a noticeable effect. Taking the medication in the morning to prevent insomnia (Choice C) is not necessary since fluoxetine can be taken at any time of the day. Instructing the client to stop taking the medication if experiencing dry mouth (Choice D) is misleading, as dry mouth is a common but usually not serious side effect of fluoxetine.

4. A nurse is assessing a client who has diabetes mellitus and is experiencing hypoglycemia. Which of the following findings should the nurse expect?

• A. Tachycardia
• B. Dry mouth
• C. Diaphoresis
• D. Increased appetite

Correct answer: C

Rationale: The correct answer is C: Diaphoresis. Diaphoresis, which is excessive sweating, is a common sign of hypoglycemia due to the activation of the sympathetic nervous system. Tachycardia (choice A) is more commonly associated with hyperglycemia. Dry mouth (choice B) is not a typical finding in hypoglycemia but may be seen in hyperglycemia. Increased appetite (choice D) is not a typical sign of hypoglycemia and is more commonly associated with hyperglycemia.

5. 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?

• A. Monitor the client's blood pressure every 4 hours.
• B. Ask the client to rate their pain every 2 hours.
• C. Administer naloxone if the client's respiratory rate is below 10/min.
• D. Evaluate the client's use of the PCA every 4 hours.

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.
