A nurse is preparing to administer a new prescription for digoxin 0.125 mg orally once daily to a client who has heart failure. Which of the following actions should the nurse take before giving the medication?

Check the client's apical pulse for one full minute.

Check the client's serum potassium level.

Check the client's blood pressure in both arms.

Check the client's serum digoxin level.

Answer and Explanation

The Correct Answer is A

A) Correct. The nurse should check the client's apical pulse for one full minute before giving digoxin as this drug can cause bradycardia and heart block. The nurse should withhold the medication and notify the provider if the pulse is less than 60 beats/min or irregular.

B) Incorrect. The nurse should check the client's serum potassium level periodically while taking digoxin as this drug can cause hypokalemia or hyperkalemia, which can affect its therapeutic effect and toxicity. However, this is not a priority action before giving each dose of digoxin.

C) Incorrect. The nurse should check the client's blood pressure in both arms periodically while taking digoxin as this drug can cause hypotension or hypertension, which can affect its efficacy and safety. However, this is not a priority action before giving each dose of digoxin.

D) Incorrect. The nurse should check the client's serum digoxin level periodically while taking digoxin as this drug has a narrow therapeutic range and can cause toxicity if the level is above 2 ng/mL. However, this is not a priority action before giving each dose of digoxin.

Correct Answer is A

Explanation

A) Correct. The nurse should advise the client to limit spinach in their diet as this food is high in vitamin K, which can antagonize the anticoagulant effect of warfarin and increase the risk of thrombosis.

B) Incorrect. The nurse should not advise the client to limit bananas in their diet as this food is high in potassium, which can help prevent hypokalemia that can occur with some anticoagulants such as heparin. Bananas do not affect the action of warfarin.

C) Incorrect. The nurse should not advise the client to limit cheese in their diet as this food is high in calcium, which can help prevent osteoporosis that can occur with long-term use of warfarin. Cheese does not affect the action of warfarin.

D) Incorrect. The nurse should not advise the client to limit eggs in their diet as this food is high in protein, which can help maintain muscle mass and wound healing that can be impaired by warfarin. Eggs do not affect the action of warfarin.

A. The nurse injects air into the NPH vial first, then into the regular vial. B. The nurse draws up regular insulin first, then NPH insulin. C. The nurse rolls the NPH vial between their palms before drawing up insulin. D. The nurse wipes the rubber stoppers of both vials with alcohol swabs.

Correct Answer is B

Explanation

A) Incorrect. The nurse should inject air into the regular vial first, then into the NPH vial. This can prevent contamination of the regular insulin with NPH insulin and ensure accurate dosing.

B) Correct. The nurse should draw up regular insulin first, then NPH insulin. This can prevent contamination of the regular insulin with NPH insulin and ensure accurate dosing. Regular insulin is clear and NPH insulin is cloudy.

C) Correct. The nurse should roll the NPH vial between their palms before drawing up insulin. This can resuspend the insulin particles that may have settled at the bottom of the vial and ensure uniform concentration.

D) Correct. The nurse should wipe the rubber stoppers of both vials with alcohol swabs before inserting needles. This can reduce the risk of infection and contamination.
