A nurse is providing teaching about client rights to a client who has a brain tumor. Which of the following client statements indicates an understanding of the teaching?

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.

The nurse should administer a total 1320ml sodium chloride in the first hour, 880ml each subsequent hour.

Rationale

First Hour Administration

Rate: 15 ml/kg/hr Client's weight: 88 kg

Calculation: 15 ml/kg/hr × 88 kg= 1320ml/hr

Therefore, in the first hour, the nurse should administer 1320 mL of 0.9% sodium chloride.

Subsequent Hour Administration

Rate: 10 ml/kg/hr Client's weight: 88 kg

Calculation: 10 ml/kg/hr × 88kg= 880mls

Therefore, each subsequent hour after the first, the nurse should administer 880 mL of 0.9% sodium chloride.
