A nurse is caring for a client who has hypertension and is prescribed metoprolol, a beta blocker. The nurse should monitor the client for which of the following adverse effects?
Choice A is wrong because tachycardia, or fast heart rate, is not an adverse effect of metoprolol. In fact, metoprolol can lower the heart rate by blocking the beta-1 receptors in the heart. A normal resting heart rate for adults ranges from 60 to 100 beats per minute (bpm). Metoprolol can cause bradycardia, or slow heart rate, which can be a serious side effect if it is too low.
Choice B is wrong because hyperglycemia, or high blood sugar, is not an adverse effect of metoprolol. Metoprolol does not affect the insulin secretion or glucose metabolism in the body. A normal blood sugar level for adults without diabetes is less than 140 mg/dL (7.8 mmol/L) two hours after eating. Metoprolol can cause hypoglycemia, or low blood sugar, in people who have diabetes and take insulin or other glucose-lowering medications. This is because metoprolol can mask the symptoms of hypoglycemia, such as palpitations and tremors.
This is because metoprolol is a beta blocker, which can block the beta-2 receptors in the lungs and cause constriction of the airways. This can lead to breathing problems such as shortness of breath, cough, and wheezing. Bronchospasm is more likely to occur in people who have asthma or chronic obstructive pulmonary disease (COPD).
Choice D is wrong because hyperkalemia, or high potassium, is not an adverse effect of metoprolol. Metoprolol does not affect the potassium balance in the body.

A normal blood potassium level for adults is 3.6 to 5.2 millimoles per liter (mmol/L)
