1. A healthcare provider in a clinic is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?

• A. Calcium 9.2 mg/dL
• B. Calcium 10.3 mg/dL
• C. Potassium 3.4 mEq/L
• D. Potassium 4.8 mEq/L

Correct answer: C

Rationale: Potassium 3.4 mEq/L is below the expected reference range, which increases the risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, particularly in older clients taking Digoxin. Hypokalemia potentiates the effects of Digoxin, making the heart more sensitive to its toxic effects. Monitoring and correcting electrolyte imbalances, especially low potassium levels, are crucial to prevent adverse effects of digoxin therapy. Calcium levels do not directly influence digoxin toxicity, so choices A and B are incorrect. High potassium levels, as in choice D, are less likely to increase the risk of digoxin toxicity compared to low potassium levels.

2. A client is starting Simvastatin. Which of the following information should be included in the teaching?

• A. Take this medication in the evening.
• B. Change positions slowly when rising from a chair.
• C. Maintain a steady intake of green leafy vegetables.
• D. Consume no more than 1 L/day of fluid.

Correct answer: A

Rationale: The correct answer is to take simvastatin in the evening. This timing is recommended because nighttime is when the most cholesterol is synthesized in the body. By taking statin medications in the evening, it can enhance their effectiveness in reducing cholesterol levels.

3. A healthcare provider is preparing to administer dextrose 5% in water (D5W) 750 mL IV to infuse over 6 hr. How many mL/hr should the IV pump be set to deliver?

• A. 125 mL/hr
• B. 100 mL/hr
• C. 150 mL/hr
• D. 200 mL/hr

Correct answer: A

Rationale: To calculate the flow rate, divide the total volume by the total time: (750 mL / 6 hr) = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse dextrose 5% in water (D5W) over 6 hours. Choice B, 100 mL/hr, is incorrect as it does not match the correct calculation. Choice C, 150 mL/hr, is incorrect as it is higher than the calculated flow rate. Choice D, 200 mL/hr, is incorrect as it is also higher than the calculated flow rate.

4. A client is starting therapy with filgrastim, and a nurse is providing teaching on monitoring adverse effects. Which of the following adverse effects should the nurse instruct the client to monitor?

• A. Bone pain
• B. Constipation
• C. Tinnitus
• D. Dry mouth

Correct answer: A

Rationale: The correct answer is A: Bone pain. The nurse should instruct the client to monitor for bone pain since it is a common adverse effect of filgrastim. This occurs due to increased bone marrow activity stimulated by the medication.

5. Which of the following is not a side effect associated with Prednisone toxicity?

• A. Cataracts
• B. Hypotension
• C. Psychosis
• D. Acne

Correct answer: B

Rationale: Prednisone toxicity is not typically associated with hypotension; instead, it can lead to hypertension. Cataracts, psychosis, and acne are known side effects of Prednisone toxicity.
