Nursing Elites

1. While reviewing a client's medical history, a healthcare professional notes a prescription for Digoxin. Which of the following findings is a manifestation of Digoxin toxicity?

• A. Elevated blood pressure
• B. Bradycardia
• C. Yellow-tinged vision
• D. Ringing in the ears

Correct answer: C

Rationale: Yellow-tinged vision is a visual disturbance associated with Digoxin toxicity, often accompanied by other symptoms like nausea, vomiting, and confusion. Bradycardia is a common therapeutic effect of Digoxin, while elevated blood pressure and ringing in the ears are not typically associated with Digoxin toxicity. Therefore, the correct answer is yellow-tinged vision as a manifestation of Digoxin toxicity.

2. Why does a nurse on an oncology unit verify a client's current cumulative lifetime dose of doxorubicin before administering it to a client with breast cancer?

• A. Excessive doxorubicin can result in myelosuppression.
• B. Exceeding the lifetime cumulative dose limit of doxorubicin may lead to extravasation.
• C. An excess amount of doxorubicin can lead to cardiomyopathy.
• D. Exceeding the lifetime cumulative dose limit of doxorubicin may cause red-tinged urine and sweat.

Correct answer: C

Rationale: Verifying the client's current cumulative lifetime dose of doxorubicin is necessary because excessive amounts of the medication can lead to cardiomyopathy, a serious and potentially life-threatening side effect. By monitoring the cumulative dose, healthcare providers can help prevent cardiotoxicity and ensure patient safety during treatment.

3. A client has been prescribed Valsartan. Which of the following adverse effects should the nurse monitor?

• A. Hyperkalemia
• B. Hypoglycemia
• C. Bradycardia
• D. Hypercalcemia

Correct answer: A

Rationale: Corrected Rationale: Valsartan is an angiotensin II receptor blocker (ARB) that can lead to hyperkalemia by inhibiting the action of aldosterone. Hyperkalemia is a potential adverse effect, making it essential for the nurse to closely monitor the client's potassium levels to prevent complications such as cardiac arrhythmias. Incorrect Options Rationale: - Option B, Hypoglycemia, is not a common adverse effect of Valsartan. - Option C, Bradycardia, is not typically associated with Valsartan use. - Option D, Hypercalcemia, is not a known adverse effect of Valsartan; instead, Valsartan can lead to hyperkalemia.

4. When teaching a client with a new prescription for Lithium, which instruction should the nurse include?

• A. Restrict fluid intake to 1,000 mL per day.
• B. Maintain a consistent sodium intake.
• C. Take the medication at bedtime.
• D. Expect to have frequent headaches.

Correct answer: B

Rationale: Maintaining a consistent sodium intake is crucial when taking Lithium to help regulate lithium levels in the body and prevent toxicity. Sodium levels can impact the effectiveness and safety of Lithium therapy. Restricting fluid intake to 1,000 mL per day (Choice A) is not appropriate and could lead to dehydration. Taking the medication at bedtime (Choice C) may vary depending on the individual's schedule but is not a critical instruction. Expecting to have frequent headaches (Choice D) is not a common side effect of Lithium.

5. A nurse is teaching a client who has a new prescription for Furosemide. Which of the following dietary instructions should the nurse provide?

• A. Increase your intake of potassium-rich foods.
• B. Limit your intake of calcium-rich foods.
• C. Avoid consuming dairy products.
• D. Increase your intake of fiber-rich foods.

Correct answer: A

Rationale: Furosemide, a loop diuretic, can cause potassium loss. Clients should increase their intake of potassium-rich foods to prevent hypokalemia.
