A nurse is caring for a client in the ICU. The client's ECG monitor tracing reveals sinus bradycardia and S-T segment elevation. The client reports shortness of breath and feeling dizzy and faint. Which of the following medications should the nurse administer?

A Advancing the weaker leg forward to the quad cane first indicates that the client understands the proper sequence of using the cane to support their weaker side. This action provides stability and reduces the risk of falls or imbalance.

B. Holding the cane with the opposite hand of the weaker side (right hand, in this case) is crucial to provide proper support and balance while walking. This distributes weight evenly and enhances stability.

C. Taking a step with the stronger foot first does not effectively support the weaker side and can lead to imbalance or falls, especially for a client with left-sided weakness.

D. While moving the cane ahead with each step is necessary, the distance of two feet is not specified in proper cane use. The cane should move forward incrementally with each step to maintain stability and support.

A Metoprolol works by blocking beta-adrenergic receptors, which can lead to bradycardia (slow heart rate) as a side effect. A heart rate of 48/min may indicate bradycardia, which can reduce cardiac output and potentially worsen symptoms in clients with heart failure.

B. Body temperature within the normal range does not indicate an adverse effect of metoprolol. Changes in temperature are not typically associated with this medication.

C. Respiratory rate within the normal range does not indicate an adverse effect of metoprolol. Respiratory changes are generally not associated with beta-blocker use.

D. Metoprolol can cause hypotension (low blood pressure) as a side effect, especially if the dosage is too high or if the client is dehydrated. However, a blood pressure of 138/76 mm Hg is within the normal range for an adult and does not necessarily indicate hypotension.
