Nursing Elites

1. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

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

• A. Hyperkalemia
• B. Hypertension
• C. Neutropenia
• D. Tinnitus

Correct answer: C

Rationale: The nurse should monitor the client for neutropenia when receiving hydroxyurea. Neutropenia is a common adverse effect caused by bone marrow suppression. It is essential to assess the client's white blood cell count regularly to detect neutropenia early and prevent complications such as infections.

3. A caregiver is being instructed by the healthcare provider of an adolescent client who has a new prescription for Albuterol, PO. Which of the following instructions should the healthcare provider include?

• A. You can take this medication to relieve an acute asthma attack.'
• B. Tremors are a potential adverse effect of this medication.'
• C. Long-term use of this medication can lead to hyperglycemia.'
• D. This medication can potentially slow the rate of skeletal growth.'

Correct answer: B

Rationale: Tremors are a possible adverse effect of Albuterol due to its stimulation of beta2 receptors in skeletal muscles. It is important for the healthcare provider to educate the caregiver about potential side effects to enhance safety and monitoring of the adolescent client.

4. 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.

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

• A. Take the medication with food.
• B. Expect a persistent, dry cough.
• C. Increase your intake of potassium-rich foods.
• D. Take the medication at bedtime.

Correct answer: B

Rationale: The correct answer is B: 'Expect a persistent, dry cough.' Lisinopril, an ACE inhibitor, commonly causes a persistent, dry cough as a side effect. This should be reported to the healthcare provider if it becomes bothersome. It is essential for the nurse to educate the client about this potential side effect so the client is aware and can seek appropriate guidance if needed. Choices A, C, and D are incorrect. Taking Lisinopril with food is not required. Increasing potassium-rich foods is not a specific instruction for Lisinopril, and taking the medication at bedtime is not a typical recommendation associated with this medication.
