Nursing Elites

1. When teaching a client with cancer who has a prescription for methotrexate, which supplement should the nurse instruct the client to take?

• A. Folic acid
• B. Magnesium
• C. Vitamin D
• D. Iron

Correct answer: A

Rationale: The correct answer is folic acid. Methotrexate is a folic acid antagonist, so instructing the client to take folic acid helps reduce the risk of methotrexate toxicity by providing additional folic acid that the medication may deplete. Magnesium (choice B), Vitamin D (choice C), and Iron (choice D) are not the correct supplements to instruct the client to take with methotrexate.

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 is receiving Gentamicin. Which of the following laboratory values should the nurse monitor to assess for nephrotoxicity?

• A. Serum sodium.
• B. Serum creatinine.
• C. Serum potassium.
• D. Serum glucose.

Correct answer: B

Rationale: When a client is receiving Gentamicin, the nurse should monitor serum creatinine levels to assess for nephrotoxicity. Gentamicin is known to potentially cause nephrotoxicity, leading to impaired kidney function. Monitoring serum creatinine levels helps in early detection of any kidney damage or dysfunction. Serum sodium, serum potassium, and serum glucose levels are not directly related to nephrotoxicity caused by Gentamicin, so they are not the appropriate values to monitor in this case.

4. A client has a new prescription for Nitroglycerin to treat angina. Which of the following instructions should be included?

• A. Take this medication only when experiencing chest pain.
• B. Store the medication in a cool, dry place.
• C. Apply the patch to a different site each time.
• D. Do not cut the patch regardless of your blood pressure.

Correct answer: C

Rationale: When using Nitroglycerin patches to treat angina, it is crucial to apply the patch to a different site each time. This practice helps prevent skin irritation and ensures proper absorption of the medication, optimizing its effectiveness in managing angina symptoms.

5. 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.
