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?

A. Dyspnea on exertion: Dyspnea on exertion is a common symptom in clients with heart failure and may indicate worsening heart function. While it warrants monitoring and potential intervention, it is not as urgent as rapid weight gain.

B. Increased urination: Increased urination may be expected with the use of diuretics, as they promote the excretion of excess fluid from the body. This finding is not typically concerning unless accompanied by other symptoms.

C. Weight gain of 2 pounds in a week: A weight gain of 2 pounds in a week may indicate fluid retention, but it is not as concerning as a rapid weight gain over a shorter period.

D. Weight gain of 3 pounds in 24 hours: A rapid weight gain of 3 pounds in 24 hours is significant and may indicate fluid overload, potentially leading to exacerbation of heart failure symptoms. It should be reported promptly to the healthcare provider for further evaluation and management.

A. Elevating the head of the bed 30 to 45 degrees helps prevent aspiration, which is a risk factor for ventilator-associated pneumonia.
B. Performing hand hygiene before touching the ventilator tubing is crucial to prevent the introduction of pathogens into the ventilator system.
C. Refraining from suctioning the client is incorrect; suctioning should be performed as needed to keep the airway clear.
D. Providing mouth care every 2-4 hours can reduce the risk of pathogens entering the lower respiratory tract.
E. Performing hand hygiene before touching the client reduces the risk of transmitting infectious agents to the client.
