1. 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.

2. 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.

3. A client has a new prescription for Efavirenz, an NNRTI. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime to prevent drowsiness.
• B. Take this medication with a glass of milk.
• C. Take this medication with a glass of juice.
• D. Take this medication at the same time every day.

Correct answer: A

Rationale: The correct instruction is to take Efavirenz at bedtime to prevent drowsiness and manage central nervous system side effects like dizziness and vivid dreams. While it is important to take the medication at the same time daily for consistent blood levels, the emphasis should be on bedtime to minimize the impact of these side effects. Choices B and C suggesting taking the medication with milk or juice are incorrect and not relevant to optimizing Efavirenz therapy.

4. A nurse is teaching a client who has a new prescription for Etanercept for Rheumatoid Arthritis. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will need to get my blood drawn periodically while on this medication.'
• B. I should stop taking this medication if I develop a rash.'
• C. I will need to limit my alcohol intake to no more than one drink per week.'
• D. I should self-administer this medication subcutaneously into the muscle.'

Correct answer: A

Rationale: Etanercept can cause bone marrow suppression, so it is important to monitor blood counts regularly.

5. A healthcare provider is assessing a client who is taking Digoxin to treat heart failure. Which of the following findings is a manifestation of digoxin toxicity?

• A. Bruising
• B. Report of metallic taste
• C. Muscle pain
• D. Report of anorexia

Correct answer: D

Rationale: The correct manifestation of digoxin toxicity is the report of anorexia. Anorexia, blurred vision, stomach pain, and diarrhea are common signs of digoxin toxicity. Bruising, metallic taste, and muscle pain are not typically associated with digoxin toxicity. Patients should promptly report symptoms of toxicity to their healthcare provider for further evaluation and management.
