A client with chronic myeloid leukemia is receiving hydroxyurea. Which of the following findings should the nurse monitor?

Correct Answer: C

Rationale: In this scenario, the correct answer is C) Neutropenia. Neutropenia is a common side effect of hydroxyurea, which is a myelosuppressive agent commonly used in the treatment of chronic myeloid leukemia. Neutropenia refers to a decreased level of neutrophils, which are crucial in fighting off infections. Therefore, monitoring for neutropenia is essential to prevent the risk of infections in the client. Option A) Hyperkalemia is not typically associated with hydroxyurea therapy, so this finding is less relevant in this context. Option B) Hypertension is not a common side effect of hydroxyurea and is not directly related to its mechanism of action or therapeutic effects in chronic myeloid leukemia. Option D) Tinnitus is not a typical side effect of hydroxyurea and is not a priority finding when monitoring a client receiving this medication for chronic myeloid leukemia. Understanding the side effects and monitoring parameters associated with specific medications is crucial for nurses caring for clients receiving these treatments. Close monitoring and early recognition of potential side effects can help in providing safe and effective care to clients undergoing pharmacological treatments for various conditions.

Correct Answer: A

Rationale: Etoposide is associated with hypotension as a common adverse effect. Therefore, the nurse should closely monitor the client for signs and symptoms of hypotension while receiving this medication, such as dizziness, light-headedness, or low blood pressure readings. Prompt recognition and management of hypotension can help prevent complications and ensure the client's safety during treatment with etoposide.

Correct Answer: A

Rationale: In educating a client prescribed Levothyroxine, instructing them to take the medication on an empty stomach (Option A) is crucial. Levothyroxine absorption is significantly reduced when taken with food, particularly high-fiber or calcium-rich foods, hence compromising its effectiveness in managing hypothyroidism. Taking it on an empty stomach ensures optimal absorption. Option B (Take this medication with food) is incorrect as it contradicts the absorption requirements of Levothyroxine. Instructing the client to take it with food would lead to decreased drug absorption and potential treatment failure. Option C (Take this medication at bedtime) is also inaccurate as Levothyroxine is best absorbed on an empty stomach in the morning, to avoid interference with sleep patterns and to maximize absorption. Option D (Take this medication with antacids) is incorrect because antacids containing calcium or aluminum can interfere with Levothyroxine absorption, reducing its efficacy. In an educational context, understanding the optimal administration of Levothyroxine is essential for clients with hypothyroidism to achieve therapeutic outcomes. By providing clear instructions on medication administration, nurses can help clients manage their condition effectively and prevent potential complications.

Correct Answer: B

Rationale: Creatine kinase should be monitored in clients taking Atorvastatin as it can indicate muscle damage, a serious adverse effect of statins. Elevated creatine kinase levels can suggest myopathy or rhabdomyolysis, which are potential complications associated with statin therapy. Monitoring creatine kinase levels helps in early detection of muscle damage and guides appropriate management to prevent severe complications.

Correct Answer: C

Rationale: In pharmacology, understanding the adverse effects of medications is crucial for safe and effective patient care. In this scenario, the correct answer is C) Bradycardia. Atenolol is a beta-blocker medication that works by slowing down the heart rate. Therefore, the client should monitor for signs of bradycardia, such as dizziness, fatigue, weakness, or fainting. Option A) Tachycardia is incorrect because Atenolol actually decreases heart rate, so an increase in heart rate would not be an expected adverse effect. Option B) Hypoglycemia is not a common adverse effect of Atenolol. Beta-blockers can mask the signs of hypoglycemia, leading to potentially dangerous consequences for clients with diabetes, but they do not directly cause hypoglycemia. Option D) Hypertension is also an incorrect option because Atenolol is actually used to treat hypertension by lowering blood pressure, so an increase in blood pressure would not be an expected adverse effect. Educationally, understanding the pharmacological actions of medications like Atenolol helps nurses provide appropriate patient education on monitoring for potential adverse effects, ensuring patient safety and optimal therapeutic outcomes.
