1. A healthcare provider is caring for a client who has a new prescription for Epoetin Alfa. Which of the following laboratory values should the healthcare provider monitor?

A. WBC count.
B. Platelet count.
C. Hemoglobin.
D. Serum potassium.

Correct answer: C

Rationale: Epoetin alfa is a medication that stimulates red blood cell production, so hemoglobin levels should be monitored to assess the effectiveness of the drug. Monitoring hemoglobin levels helps evaluate the response to Epoetin Alfa treatment and ensures that the client's anemia is being appropriately managed.

2. A nurse is providing teaching to a client who has asthma and is beginning to take montelukast. Which of the following statements by the client indicates an understanding of the teaching?

A. I will use this medication as a rescue inhaler during asthma attacks.
B. I should take this medication once daily in the evening.
C. I need to have my blood levels checked regularly while taking this medication.
D. I should take this medication before exercising to prevent bronchospasm.

Correct answer: B

Rationale: Montelukast is typically taken once daily in the evening for long-term control of asthma symptoms. It helps prevent asthma attacks by reducing inflammation in the airways. While montelukast can also be used for exercise-induced bronchospasm in some cases, it is generally not a rescue medication and should be taken regularly, not on an as-needed basis.

3. A client is receiving treatment with methotrexate. Which of the following supplements should the nurse instruct the client to take?

A. Folic acid
B. Vitamin D
C. Calcium
D. Iron

Correct answer: A

Rationale: The nurse should instruct the client to take folic acid when receiving treatment with methotrexate to reduce the risk of methotrexate toxicity. Methotrexate acts as a folic acid antagonist, leading to folic acid deficiency, which can be counteracted by supplementing with folic acid. Vitamin D, calcium, and iron are not specifically recommended to counteract methotrexate effects and do not play a significant role in mitigating methotrexate toxicity.

4. When taking Digoxin, low levels of what can cause toxicity?

A. Potassium
B. Calcium
C. Sodium
D. Magnesium

Correct answer: A

Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.

5. Which medication is used as a bronchodilator?

A. Warfarin
B. Lovastatin
C. Albuterol
D. Valproate

Correct answer: C

Rationale: Albuterol is the correct answer. It is a medication commonly used as a bronchodilator to treat conditions such as asthma. Albuterol works by relaxing the muscles in the airways, allowing better airflow and making breathing easier for individuals with respiratory conditions. Warfarin (Choice A) is an anticoagulant used to prevent blood clots, Lovastatin (Choice B) is a medication used to lower cholesterol levels, and Valproate (Choice D) is used to treat seizures and bipolar disorder. These medications are not bronchodilators and are used for different medical conditions.
