A client who is receiving magnesium sulfate has a urine output of 20 mL/hr. Which of the following medications should the nurse expect to administer?

Choice A reason: Expecting to gain weight while taking this medication is not a correct instruction, as it may discourage the client from adhering to the treatment and may worsen the hypertension. Captopril is an angiotensin-converting enzyme (ACE) inhibitor that lowers the blood pressure by preventing the formation of angiotensin II, a potent vasoconstrictor. Captopril does not cause significant weight gain, but it may cause fluid retention or edema in some cases. The nurse should advise the client to monitor the weight daily and report any sudden or excessive increase to the provider.

Choice B reason: Not using salt substitutes while taking this medication is a correct instruction, as it may prevent the risk of hyperkalemia, a potentially life-threatening condition. Captopril may increase the potassium level in the blood by reducing the secretion of aldosterone, a hormone that regulates the sodium and potassium balance. Salt substitutes may contain potassium chloride, which may further elevate the potassium level. The nurse should advise the client to avoid salt substitutes and high-potassium foods, such as bananas, oranges, or tomatoes, and to have regular blood tests to check the electrolyte levels.

Choice C reason: Counting the pulse rate before taking the medication is not a necessary instruction, as it may not reflect the effect of the medication on the blood pressure. Captopril does not affect the heart rate significantly, but it may lower the blood pressure too much, especially in the first few weeks of treatment or after a dose increase. This may cause hypotension, dizziness, or fainting. The nurse should advise the client to monitor the blood pressure regularly and report any symptoms of hypotension to the provider.

Choice D reason: Taking the medication with food is not a correct instruction, as it may reduce the absorption and effectiveness of the medication. Captopril should be taken on an empty stomach, at least one hour before or two hours after a meal, to ensure optimal bioavailability. The nurse should advise the client to take the medication at the same time every day and to avoid skipping or doubling the doses.

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.
