Nursing Elites

1. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:

• A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
• B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
• C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
• D. To lower blood glucose by stimulating the release of insulin

Correct answer: A

Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.

2. A client with congestive heart failure taking digoxin refused breakfast and is complaining of nausea and weakness. Which action should the nurse take first?

• A. Check the client's vital signs.
• B. Request a consult with a dietitian.
• C. Suggest that the client rests before eating the meal.
• D. Request an order for an antiemetic.

Correct answer: A

Rationale: The nurse should check the client's vital signs first because nausea and weakness can be signs of digoxin toxicity. Vital signs can provide immediate information on the client's condition and help guide further interventions. Monitoring vital signs will allow the nurse to assess for bradycardia, a common sign of digoxin toxicity. Requesting a dietitian consult (choice B) may be necessary but addressing the immediate concern of toxicity is the priority. Suggesting rest before eating (choice C) may not address the underlying issue of digoxin toxicity. Requesting an antiemetic (choice D) can be considered later but is not the initial action needed in this situation.

3. A client has a new prescription for Warfarin. Which of the following herbal supplements should the client be instructed to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

Correct answer: A

Rationale: St. John's wort should be avoided by clients taking Warfarin as it can reduce the medication's effectiveness by affecting its metabolism. Echinacea, garlic, and ginseng are also known to interact with Warfarin, either by increasing the risk of bleeding or altering its anticoagulant effects. However, St. John's wort is particularly significant due to its potent enzyme-inducing properties that can lead to subtherapeutic levels of Warfarin, potentially increasing the risk of blood clots.

4. A client with Depression has a new prescription for Venlafaxine. For which of the following adverse effects should the nurse monitor this client? (Select all that apply)

• A. Cough
• B. Dizziness
• C. Decreased libido
• D. B and C

Correct answer: D

Rationale: The correct answer is D: 'B and C.' Venlafaxine, a medication used to treat depression, can lead to adverse effects like dizziness and decreased libido. It is important for the nurse to monitor the client for these potential side effects. Cough and alopecia are not typically associated with Venlafaxine. Therefore, choices A (Cough) and C (Decreased libido) are incorrect. Dizziness and decreased libido are the adverse effects that the nurse should focus on when monitoring a client on Venlafaxine treatment.

5. A client is prescribed Nitroglycerin sublingual tablets. Which of the following instructions should the nurse include during discharge teaching?

• A. Take the medication with food.
• B. Store the medication in a cool, dry place.
• C. Swallow the tablets whole.
• D. Take one tablet every 5 minutes up to three doses for chest pain.

Correct answer: D

Rationale: During a chest pain episode, the client should take one nitroglycerin tablet sublingually every 5 minutes up to a total of three doses. If chest pain persists after three doses, emergency medical attention should be sought. Nitroglycerin should not be swallowed but allowed to dissolve under the tongue for rapid absorption. Storing the medication in a cool, dry place helps maintain its effectiveness.
