A nurse is preparing to perform a 12-lead electrocardiogram. Which of the following instructions should the nurse provide to the client while applying the electrode gel pads?

"I will be placing electrodes on your breasts."

"I will lower the head of your bed so you can lie flat."

"Relax and try not to move or speak once I have attached the gel pads."

"Try to hold your breath until this procedure is complete."

Answer and Explanation

The Correct Answer is C

A. "I will be placing electrodes on your breasts": This statement is incorrect and may cause unnecessary concern or discomfort for the client. Electrodes for a 12-lead electrocardiogram are typically placed on the chest, not the breasts.

B. "I will lower the head of your bed so you can lie flat": This statement may be relevant for certain procedures but is not specific to applying electrode gel pads for a 12-lead electrocardiogram.

C. "Relax and try not to move or speak once I have attached the gel pads": This instruction is essential for obtaining a clear and accurate electrocardiogram recording. Movement or talking during the procedure can interfere with the quality of the tracing.

D. "Try to hold your breath until this procedure is complete": This instruction is unnecessary and could cause discomfort or anxiety for the client. There is no need for the client to hold their breath during a standard electrocardiogram procedure.

Correct Answer is B

Explanation

A. Morphine sulfate 2 mg IV bolus every 2 hr PRN pain: This prescription is appropriate for managing pain associated with acute heart failure and MI.

B. Bumetanide 1 mg IV bolus every 12 hr: Bumetanide is a loop diuretic commonly used in heart failure to reduce fluid overload. However, the frequency of administration (every 12 hours) may not be sufficient for managing acute heart failure, where more frequent dosing may be necessary initially.

C. Laboratory testing of serum potassium upon admission: This is a routine and appropriate order to monitor electrolyte balance, especially with the use of diuretics.

D. 0.9% normal saline IV at 75 mL/hr: This is a maintenance IV fluid rate that may be appropriate depending on the client's fluid status. However, it does not directly address acute heart failure.

A. Client develops petechiae on the arms, legs, and abdomen. B. Health care provider orders Coumadin 2.5 mg P.O. to begin today. C. Client develops slight ecchymosis at the venipuncture site. D. Client's partial thromboplastin time (PTT) is 70 seconds and the control is 25-40 seconds.

Correct Answer is D

Explanation

A. Client develops petechiae on the arms, legs, and abdomen: Petechiae can indicate thrombocytopenia, which may be a complication of heparin therapy but is not an urgent concern unless severe or associated with bleeding.

B. Health care provider orders Coumadin 2.5 mg P.O. to begin today: Coumadin (warfarin) is often initiated as a bridge therapy or overlap with heparin therapy in pulmonary embolism management. This order is not necessarily inappropriate and may be part of the treatment plan.

C. Client develops slight ecchymosis at the venipuncture site: Ecchymosis at the venipuncture site can occur due to minor trauma during the insertion of IV lines or blood draws and is not necessarily indicative of a complication requiring immediate notification of the healthcare provider.

D. Client's partial thromboplastin time (PTT) is 70 seconds and the control is 25-40 seconds: A significantly elevated PTT indicates a potential overdose of heparin, putting the client at risk of bleeding complications. This finding warrants immediate notification of the healthcare provider for further evaluation and possible adjustment of heparin therapy.
