Nursing Elites

1. A nurse is caring for a client who is prescribed warfarin. Which of the following laboratory tests should the nurse review to evaluate the therapeutic effect of this medication?

• A. aPTT
• B. INR
• C. Serum glucose
• D. Bilirubin

Correct answer: B

Rationale: The correct answer is B: INR. The International Normalized Ratio (INR) is the most reliable test for evaluating the therapeutic effects of warfarin therapy. INR measures the clotting ability of the blood and helps determine if the dosage of warfarin is within the therapeutic range. Choice A, aPTT, is not typically used to monitor the effects of warfarin. Choice C, Serum glucose, and choice D, Bilirubin, are not relevant to monitoring the therapeutic effect of warfarin.

2. A client prescribed hydromorphone for severe pain has a decreased respiratory rate from 16 breaths per minute to 6. Which of the following medications should the nurse prepare to administer?

• A. Flumazenil
• B. Naloxone
• C. Activated charcoal
• D. Aluminum hydroxide

Correct answer: B

Rationale: Naloxone is the correct answer as it is used to reverse opioid-induced respiratory depression. Hydromorphone is an opioid medication that can cause respiratory depression at high doses. Naloxone is an opioid antagonist that competes with opioids at receptor sites, reversing the effects of opioids like hydromorphone. Flumazenil (Choice A) is a benzodiazepine antagonist used for benzodiazepine overdose, not opioid overdose. Activated charcoal (Choice C) is used for toxin ingestion to prevent absorption in the gastrointestinal tract, but it is not indicated for opioid overdose. Aluminum hydroxide (Choice D) is an antacid and would not be the appropriate intervention for respiratory depression caused by opioid overdose.

3. A nurse is preparing to administer morphine sulfate 2 mg IV bolus. Available is morphine sulfate 10 mg/mL. How many mL should the nurse administer per dose?

• A. 0.2 mL
• B. 0.4 mL
• C. 0.6 mL
• D. 0.8 mL

Correct answer: A

Rationale: The nurse should administer 0.2 mL of morphine sulfate. To calculate this, divide the desired dose (2 mg) by the concentration of the available solution (10 mg/mL). 2 mg / 10 mg/mL = 0.2 mL. Therefore, the nurse should administer 0.2 mL of morphine sulfate. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided concentration and desired dose.

4. A nurse is caring for a client receiving theophylline for chronic obstructive pulmonary disease (COPD). Which of the following client findings indicates the need for immediate intervention?

• A. Productive cough
• B. Drowsiness
• C. Vomiting
• D. Polyuria

Correct answer: D

Rationale: Polyuria is a sign of theophylline toxicity and requires immediate intervention. Theophylline toxicity can lead to serious complications, and polyuria is a concerning symptom that indicates the need for urgent medical attention. Productive cough, drowsiness, and vomiting are common side effects of theophylline but are not typically indicative of immediate life-threatening issues like polyuria in the context of theophylline toxicity.

5. A nurse is preparing to administer furosemide to a client. Which of the following findings indicates the client may be at risk for an adverse effect of the medication?

• A. Hypertension
• B. Hypokalemia
• C. Increased urine output
• D. Hyperglycemia

Correct answer: B

Rationale: The correct answer is B: Hypokalemia. Furosemide is a loop diuretic that can cause potassium depletion, leading to hypokalemia, which is a common adverse effect. Hypokalemia can result in serious complications like cardiac arrhythmias. Choices A, C, and D are not directly associated with the adverse effects of furosemide. Hypertension is a condition that furosemide is often used to treat, increased urine output is an expected effect of furosemide, and hyperglycemia is not a typical adverse effect of this medication.
