Nursing Elites

1. When reviewing a client's health record, a healthcare professional notes that the client is experiencing episodes of hypokalemia. Which of the following medications should be identified as a cause of the client's hypokalemia?

• A. Captopril
• B. Lisinopril
• C. Furosemide
• D. Spironolactone

Correct answer: C

Rationale: Furosemide, a loop diuretic, can lead to hypokalemia by increasing the excretion of potassium in the urine. This potassium loss can result in lower-than-normal levels of potassium in the body, leading to hypokalemia.

2. When providing discharge instructions to a client prescribed Warfarin, which herbal supplement should the nurse instruct the client 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 interacting with its metabolism. While garlic and ginseng are also known to interact with Warfarin, the specific supplement the nurse should instruct the client to avoid in this scenario is St. John's wort. Echinacea, although an herbal supplement, is not typically associated with significant interactions with Warfarin and is not the primary concern in this case.

3. Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?

• A. Heparin
• B. Alprazolam
• C. Digoxin
• D. Levothyroxine

Correct answer: C

Rationale: Digoxin is the correct answer. It is a medication known for its positive inotropic effects, which increase cardiac output, and negative chronotropic effects, which slow the heart rate. These effects are achieved by inhibiting the sodium-potassium ATPase pump in myocardial cells. Therefore, Digoxin is commonly prescribed to manage conditions like heart failure and atrial fibrillation, where enhancing cardiac output and reducing heart rate are beneficial. Choices A, B, and D are incorrect because Heparin is an anticoagulant, Alprazolam is a benzodiazepine used for anxiety disorders, and Levothyroxine is a thyroid hormone replacement drug, none of which have the specified therapeutic effects on cardiac function.

4. What classification of drug is Penicillin?

• A. Antiarrhythmic
• B. Anticonvulsant
• C. Antibacterial
• D. Mood stabilizer

Correct answer: C

Rationale: Penicillin is classified as an antibacterial drug, specifically used to treat bacterial infections. It works by inhibiting the growth of bacteria, making it an effective treatment for various bacterial infections. Choices A, B, and D are incorrect as Penicillin does not belong to these drug classifications. Penicillin does not have any direct effect on heart rhythm (antiarrhythmic), does not treat seizures (anticonvulsant), and is not used to stabilize mood (mood stabilizer).

5. Which of the following is not a side effect of the vasodilator Nifedipine?

• A. Nausea
• B. Flushed appearance
• C. Vertigo
• D. Sexual dysfunction

Correct answer: D

Rationale: Sexual dysfunction is not a common side effect of vasodilators such as Nifedipine. Nausea, flushed appearance, and vertigo are more commonly reported side effects associated with this medication. It's essential for healthcare providers to be aware of the potential side effects to monitor and manage them effectively in patients prescribed with Nifedipine.
