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?

"The extra letters after the name of the medication mean it is a stronger dose."

"I will not have to do anything different because it is the same medication."

"Now I will not have to diet to lose weight."

"With the new medication, I should experience fewer side effects."

Answer and Explanation

The Correct Answer is D

Choice A reason: The extra letters after the name of the medication do not mean it is a stronger dose, but that it is a combination of two different medications. Metoprolol is a beta-blocker that lowers blood pressure and heart rate, while hydrochlorothiazide is a diuretic that reduces fluid retention and blood volume. The combination of these two medications may have a synergistic effect and lower blood pressure more effectively than either one alone.

Choice B reason: The client will have to do some things differently because it is not the same medication, but a combination of two medications. The client will have to monitor their blood pressure, weight, fluid intake, and electrolyte levels more closely, as the addition of hydrochlorothiazide may increase the risk of dehydration, hypotension, and hypokalemia. The client will also have to avoid alcohol, salt, and potassium supplements, as they may interact with the medication and affect its efficacy or safety.

Choice C reason: The client will still have to diet to lose weight, as the medication does not cause weight loss, but may cause weight gain due to fluid retention. The client will have to follow a healthy diet that is low in sodium, fat, and cholesterol, as these may worsen hypertension and increase the risk of cardiovascular complications. The client will also have to exercise regularly, as this may help lower blood pressure and improve overall health.

Choice D reason: The client may experience fewer side effects with the new medication, as the combination of metoprolol and hydrochlorothiazide may lower the dose and frequency of each medication, and reduce the adverse effects of each one. For example, metoprolol may cause fatigue, dizziness, or bradycardia, while hydrochlorothiazide may cause dry mouth, headache, or gout. The combination of these two medications may balance out these effects and improve the client's tolerance and compliance.

Correct Answer is C

Explanation

Choice A reason: This is incorrect because extravasation is not related to the lifetime cumulative dose limit of doxorubicin, but to the leakage of the medication from the vein into the surrounding tissue. Extravasation can cause severe tissue damage and necrosis, and should be prevented by using a central venous catheter and monitoring the infusion site.

Choice B reason: This is incorrect because red tinged urine and sweat are not related to the lifetime cumulative dose limit of doxorubicin, but to the normal excretion of the medication from the body. Red tinged urine and sweat are expected side effects of doxorubicin and do not indicate toxicity or harm.

Choice C reason: This is correct because an excess amount of doxorubicin can lead to cardiomyopathy, which is a serious and potentially fatal complication of the medication. Cardiomyopathy is a condition in which the heart muscle becomes weak and unable to pump blood effectively. The risk of cardiomyopathy increases with the cumulative lifetime dose of doxorubicin, which should not exceed 450 to 550 mg/m2.

Choice D reason: This is incorrect because myelosuppression is not related to the lifetime cumulative dose limit of doxorubicin, but to the dose-dependent effect of the medication on the bone marrow. Myelosuppression is a condition in which the production of blood cells is reduced, leading to anemia, leukopenia, and thrombocytopenia. Myelosuppression can be managed by adjusting the dose and frequency of doxorubicin and monitoring the blood counts.

A. Use an electric razor while on this medication. B. If a dose of the medication is missed, double the dose at the next scheduled time. C. Mild nosebleeds are common during initial treatment. D. Increase fiber intake to reduce the adverse effect of constipation.

Correct Answer is A

Explanation

Choice A reason: Using an electric razor while on warfarin is the correct instruction. Warfarin is an anticoagulant that inhibits the formation of blood clots and prolongs the bleeding time. Using an electric razor can reduce the risk of cuts and bleeding while shaving. The client should avoid using sharp objects or instruments that can cause injury or trauma.

Choice B reason: Doubling the dose of warfarin if a dose is missed is not the correct instruction. This is a dangerous and potentially fatal advice, as it can cause overdose and severe bleeding. The client should take the missed dose as soon as possible, unless it is close to the next scheduled dose, in which case the client should skip the missed dose and resume the regular dosing schedule. The client should never take extra doses or change the dose without consulting the provider.

Choice C reason: Mild nosebleeds being common during initial treatment is not the correct instruction. This is a false and misleading statement, as nosebleeds are not a normal or expected side effect of warfarin therapy. Nosebleeds can indicate bleeding problems or complications, such as thrombocytopenia, which is a low platelet count. The client should report any nosebleeds or other signs of bleeding, such as bruising, petechiae, hematuria, or melena, to the provider immediately.

Choice D reason: Increasing fiber intake to reduce the adverse effect of constipation is not the correct instruction. This is an irrelevant and unnecessary recommendation, as constipation is not a common or serious adverse effect of warfarin therapy. Constipation can be caused by many factors, such as diet, hydration, activity, or medication. The client should maintain a balanced and consistent diet, drink plenty of fluids, and exercise regularly to prevent constipation. The client should also avoid foods that are high in vitamin K, such as green leafy vegetables, as they can interfere with the effect of warfarin.
