Nursing Elites

1. The nurse is informed during shift report that a client is experiencing occasional ventricular dysrhythmias. The nurse reviews the client's laboratory results, recalling that which electrolyte imbalance could be responsible for this development?

• A. Hypokalemia
• B. Hypernatremia
• C. Hypochloremia
• D. Hypercalcemia

Correct answer: A

Rationale: Hypokalemia, which is low potassium levels, can disrupt the normal electrical activity of the heart and lead to ventricular dysrhythmias. Potassium plays a crucial role in maintaining the heart's rhythm, and a deficiency can result in dangerous heart rhythm abnormalities. Hypernatremia (Choice B), which is high sodium levels, does not directly impact heart rhythm. Hypochloremia (Choice C), which is low chloride levels, is not typically associated with ventricular dysrhythmias. Hypercalcemia (Choice D), which is high calcium levels, is not a common cause of ventricular dysrhythmias.

2. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin (Coumadin). The nurse should include which instruction in the discharge teaching?

• A. Take the medication at the same time each day
• B. Avoid green leafy vegetables in your diet
• C. Increase your intake of vitamin K-rich foods
• D. Stop the medication if you notice any bruising

Correct answer: A

Rationale: Taking warfarin at the same time each day is crucial to maintain consistent blood levels and ensure the effectiveness of the medication in preventing clot formation. Consistent timing helps in monitoring and adjusting the dosage as needed to keep the international normalized ratio (INR) within the therapeutic range to prevent clotting events or excessive bleeding. Choices B, C, and D are incorrect. Avoiding green leafy vegetables is a misconception; while they are high in vitamin K which antagonizes warfarin, they should not be avoided but consumed in moderation. Increasing vitamin K-rich foods can interfere with warfarin's effectiveness. Stopping the medication due to bruising can be dangerous as it may indicate a clotting problem that the medication is intended to prevent.

3. A client has a new prescription for heparin. Which of the following laboratory results should be monitored to evaluate the effectiveness of the medication?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the laboratory result that should be monitored to evaluate the effectiveness of heparin. Heparin works by prolonging the aPTT, and monitoring this parameter helps ensure the medication's effectiveness and safety in preventing clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor the effectiveness of warfarin, another anticoagulant. Platelet count is essential to assess platelet function and clotting disorders, but it is not specifically used to monitor heparin therapy.

4. A healthcare professional is assessing a client who has a new prescription for enalapril. Which of the following findings should the professional report to the provider?

• A. Frequent urination
• B. Dry cough
• C. Tremors
• D. Dizziness

Correct answer: B

Rationale: The correct answer is B: Dry cough. A dry cough is a common side effect of enalapril that can indicate the development of angioedema or potentially life-threatening angioedema. An onset of dry cough should be reported to the provider promptly as it may require discontinuation of the medication to prevent further complications. Frequent urination, tremors, and dizziness are not typically associated with enalapril use and are less likely to be of immediate concern compared to a dry cough in this context.

5. A client with chronic stable angina is prescribed nitroglycerin (Nitrostat) for chest pain. The nurse should include which instruction when teaching the client about this medication?

• A. Take nitroglycerin at the first sign of chest pain.
• B. Swallow the tablet whole with water.
• C. Take nitroglycerin with meals to prevent stomach upset.
• D. Store nitroglycerin in a cool, dry place.

Correct answer: A

Rationale: The correct instruction when teaching a client about nitroglycerin (Nitrostat) is to take it at the first sign of chest pain. Nitroglycerin works rapidly to dilate blood vessels, improving blood flow to the heart muscle. Taking it promptly can help alleviate symptoms quickly and prevent the condition from worsening. Choice B is incorrect because nitroglycerin is usually taken sublingually (under the tongue) and not swallowed. Choice C is incorrect because nitroglycerin is not typically taken with meals. Choice D is incorrect because nitroglycerin should be stored in its original container away from heat and light.
