Nursing Elites

1. A client with heart failure is receiving digoxin. Which finding should indicate to the nurse that the client is experiencing digoxin toxicity?

• A. Constipation
• B. Blurred vision
• C. Bradycardia
• D. Dry cough

Correct answer: C

Rationale: Bradycardia is a hallmark sign of digoxin toxicity. Digoxin, a medication used to treat heart conditions, can lead to toxicity manifesting as bradycardia. Bradycardia occurs due to the drug's effect on slowing down the heart rate excessively. Constipation (Choice A) is not typically associated with digoxin toxicity. Blurred vision (Choice B) is more commonly linked to visual disturbances caused by digoxin, but it is not a defining sign of toxicity. Dry cough (Choice D) is not a recognized symptom of digoxin toxicity. It is crucial for the nurse to recognize the early signs of digoxin toxicity to prevent serious complications and provide appropriate interventions promptly.

2. The client is receiving anticoagulant therapy for atrial fibrillation. Which laboratory test should be monitored to determine the effectiveness of the therapy?

• A. Prothrombin time (PT) and international normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Platelet count
• D. Erythrocyte sedimentation rate (ESR)

Correct answer: A

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of anticoagulant therapy in clients with atrial fibrillation. These tests help ensure that the client is within the therapeutic range and are commonly used to assess the clotting ability of the blood. Monitoring PT and INR levels allows healthcare providers to adjust anticoagulant dosages as needed to prevent complications such as bleeding or thrombosis. Activated partial thromboplastin time (aPTT) is more commonly used to monitor heparin therapy, not anticoagulant therapy for atrial fibrillation. Platelet count assesses the number of platelets in the blood and is not a direct indicator of anticoagulant therapy effectiveness. Erythrocyte sedimentation rate (ESR) is a nonspecific marker of inflammation and is not used to monitor anticoagulant therapy.

3. A client has been taking levothyroxine for 6 months. Which of the following findings indicates that the medication is effective?

• A. Weight gain
• B. Increased heart rate
• C. Decreased TSH levels
• D. Elevated blood pressure

Correct answer: C

Rationale: In a client taking levothyroxine for thyroid hormone replacement, decreased TSH levels indicate that the medication is effective. TSH levels decrease as the thyroid hormone levels are adequately replaced by levothyroxine, signaling a positive response to treatment. Choices A, B, and D are incorrect because weight gain, increased heart rate, and elevated blood pressure are not expected findings indicating the effectiveness of levothyroxine therapy. Weight gain may suggest inadequate dosing, while increased heart rate and elevated blood pressure could indicate over-replacement or side effects of the medication.

4. A client has a new prescription for lisinopril. Which of the following findings should be reported to the provider by the nurse?

• A. Weight gain
• B. Dry cough
• C. Hypokalemia
• D. Increased appetite

Correct answer: B

Rationale: The correct answer is B - Dry cough. Lisinopril is known to cause a persistent dry cough as a common side effect. This adverse reaction can be bothersome to the client and may necessitate discontinuation of the medication. Weight gain, hypokalemia, and increased appetite are not typically associated with lisinopril and would not be as concerning as a dry cough when assessing for adverse effects.

5. A client with a history of myocardial infarction (MI) is being discharged with a prescription for nitroglycerin sublingual tablets. Which instruction should the nurse reinforce?

• A. Store the tablets in a cool, dry place away from light.
• B. Take a tablet every 5 minutes if chest pain occurs.
• C. Place the tablets under the tongue for sublingual absorption.
• D. Take the tablets without water for faster effect.

Correct answer: A

Rationale: The correct answer is A. Nitroglycerin tablets are light and moisture-sensitive, so they should be stored in a cool, dry place away from light to maintain their effectiveness. Option B advises taking a tablet every 5 minutes, which may lead to overdose as this frequency is too high. Option C emphasizes the correct administration route for sublingual tablets. Option D is incorrect as water is not needed for the tablets to take effect.
