A nurse is providing teaching for a client who has hypertension and a prescription change from metoprolol to metoprolol/hydrochlorothiazide. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason: Bleeding gums is a possible adverse effect of taking gingko biloba, as it may increase the risk of bleeding by inhibiting platelet aggregation and interfering with clotting factors. Gingko biloba may also interact with other medications that affect bleeding, such as anticoagulants, antiplatelets, or NSAIDs. The nurse should advise the client to monitor for signs of bleeding, such as bruising, nosebleeds, or hematuria, and report them to the provider.

Choice B reason: Decreased alertness is not a likely adverse effect of taking gingko biloba, as it may have the opposite effect of enhancing cognitive function and memory. Gingko biloba may improve blood flow to the brain and protect against oxidative stress and neuronal damage. The nurse should inform the client that gingko biloba may take several weeks to show its benefits and that the evidence for its effectiveness is inconclusive.

Choice C reason: Breast enlargement is not a known adverse effect of taking gingko biloba, as it does not affect the hormonal levels or the breast tissue. Gingko biloba may have some estrogenic activity, but it is not significant enough to cause gynecomastia or breast tenderness. The nurse should assess the client for other possible causes of breast enlargement, such as medications, liver disease, or tumors.

Choice D reason: Bad breath is not a common adverse effect of taking gingko biloba, as it does not affect the oral hygiene or the digestive system. Gingko biloba may have a mild odor, but it is not unpleasant or persistent. The nurse should advise the client to maintain good oral care and to check for other possible causes of bad breath, such as infections, dental problems, or dietary factors.

The Correct answer is A.

Choice A reason: Evaluating the client for nausea, vomiting, and anorexia is important because these are common signs of digoxin toxicity. Digoxin is a cardiac glycoside used to treat heart failure and certain arrhythmias, but it has a narrow therapeutic window. Toxicity can occur due to various factors, including renal insufficiency or drug interactions. Monitoring gastrointestinal symptoms like nausea, vomiting, and loss of appetite can help detect toxicity early.

Choice B reason: Withholding digoxin if the heart rate is above 100/min is not typically recommended. Digoxin has a negative chronotropic effect, meaning it can decrease heart rate. However, the decision to withhold medication usually depends on a heart rate that is too low (bradycardia), not high. The normal range for resting heart rate in adults is 60-100 beats per minute. Therefore, withholding digoxin for a heart rate above 100/min without other clinical justifications would not be appropriate.

Choice C reason: Measuring the apical pulse rate for 30 seconds before administration is not the standard practice. The apical pulse should be measured for a full minute to ensure accuracy, especially in clients with heart failure who are receiving digoxin. This is because digoxin can cause arrhythmias, and a shorter measurement period may not provide a true representation of the heart's rhythm.

Choice D reason: Instructing the client to eat foods that are low in potassium is incorrect. Clients taking digoxin should maintain a normal potassium level, as hypokalemia can increase the risk of digoxin toxicity. The normal serum potassium level is 3.5-5.0 mEq/L. Foods high in potassium can help maintain this balance and should not be avoided unless there is a specific clinical indication, such as hyperkalemia.
