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 C

Explanation

A. Joint contractures: Joint contractures are a common manifestation of systemic scleroderma, but they are not directly related to altered tissue perfusion. They are more related to skin and tissue fibrosis.

B. Peripheral arterial dilation: Peripheral arterial dilation is not typically associated with systemic scleroderma. Instead, peripheral vasoconstriction, such as in Raynaud's phenomenon, is more common.

C. Raynaud's phenomenon: Raynaud's phenomenon, characterized by episodic vasospasm of small arteries in response to cold or stress, can lead to impaired tissue perfusion, especially in the extremities.

D. Pulmonary fibrosis: Pulmonary fibrosis is a complication of systemic scleroderma that affects lung tissue, but it is not directly related to altered tissue perfusion. It may lead to impaired gas exchange rather than altered perfusion.

A. Lime B. Hydrofluric acid C. Bleach D. Fabric softener E. Gasoline

C. Bleach: Bleach, particularly sodium hypochlorite, is a common household chemical that can cause chemical burns, especially in concentrated forms.
