A nurse is assessing a client who has heart failure and is receiving metoprolol. Which of the following statements by the client indicates a therapeutic effect of the medication?
A. “I have less swelling in my ankles.”
Choice A is wrong because “I have less swelling in my ankles.” This statement indicates a possible effect of a diuretic, which is a medication that reduces fluid retention and edema by increasing urine output. Metoprolol does not have a direct diuretic effect, although it may indirectly reduce fluid accumulation by improving cardiac function.
B. “I can walk farther without getting tired.”
The correct answer is choice B. “I can walk farther without getting tired.” This statement indicates a therapeutic effect of metoprolol, which is a beta-blocker that reduces the heart rate, blood pressure, and the workload of the heart. This helps to improve the blood flow and oxygen delivery to the heart and other organs, and reduces the symptoms of heart failure such as fatigue, dyspnea, and edema.
C. “I don’t have chest pain anymore.”
Choice C is wrong because “I don’t have chest pain anymore.” This statement indicates a possible effect of a nitrate, which is a medication that dilates the blood vessels and reduces the oxygen demand of the heart. Metoprolol may also help to prevent or treat angina by lowering the heart rate and blood pressure, but it is not the primary medication for chest pain relief.
D. “I can breathe better at night.”.
Choice D is wrong because “I can breathe better at night.” This statement indicates a possible effect of an oxygen therapy, which is a treatment that delivers supplemental oxygen to the lungs and improves gas exchange. Metoprolol may also help to reduce dyspnea by improving cardiac function and reducing pulmonary congestion, but it is not the primary treatment for respiratory distress.

Similar Questions
A nurse is evaluating a client who has heart failure and is receiving warfarin. Which of the following statements by the client indicates a need for further teaching?
A. “I will use an electric razor for shaving.”
Choice A is wrong because using an electric razor for shaving is a safe practice for a client who is receiving warfarin, as it reduces the risk of bleeding from cuts or nicks.
B. “I will eat more green leafy vegetables.”
Choice B is wrong because “I will eat more green leafy vegetables.” This statement indicates a need for further teaching because green leafy vegetables are high in vitamin K, which can antagonize the effects of warfarin and increase the risk of clotting. The client should be advised to maintain a consistent intake of vitamin K and avoid sudden changes in their diet.
C. “I will check my stools for blood.”
Choice C is wrong because checking stools for blood is an important measure for a client who is receiving warfarin, as it can indicate gastrointestinal bleeding, which is a serious adverse effect of the medication.
D. “I will have my blood drawn regularly.”.
Choice D is wrong because having blood drawn regularly is necessary for a client who is receiving warfarin, as it allows the monitoring of the international normalized ratio (INR), which reflects the degree of anticoagulation and guides the dosage adjustment of the medication.

The normal range for INR for a client who is receiving warfarin is 2 to 3, unless otherwise specified by the provider.
A nurse is planning to administer mannitol to a client who has heart failure and pulmonary edema. Which of the following actions should the nurse take before giving the medication?
A. Check the urine output.
Mannitol is an osmotic diuretic that increases urine output and decreases intracranial pressure and intraocular pressure. The nurse should check the urine output before giving the medication to ensure adequate renal function and prevent fluid overload and electrolyte imbalance. The normal urine output is 0.5 to 1 mL/kg/hr.
B. Check the blood pressure.
Choice B is wrong because checking the blood pressure is not specific to mannitol administration. Mannitol can cause hypotension or hypertension depending on the fluid status of the client, but this is not the priority action before giving the medication.
C. Check the blood glucose.
Choice C is wrong because checking the blood glucose is not relevant to mannitol administration. Mannitol does not affect blood glucose levels.
D. Check the oxygen saturation.
Choice D is wrong because checking the oxygen saturation is not related to mannitol administration. Mannitol does not affect oxygen saturation levels.

The nurse is caring for a patient with chronic heart failure who has been prescribed digoxin (Lanoxin). The patient’s apical pulse rate is 58 beats/min. What should the nurse do next?
A. Administer the medication as ordered.
Choice A is wrong because administering the medication as ordered could worsen the patient’s condition and increase the risk of digoxin toxicity.
B. Hold the medication and notify the provider.
Digoxin (Lanoxin) is a cardiac glycoside that is used to improve the contractility of the heart and slow down the heart rate in patients with chronic heart failure. However, digoxin has a narrow therapeutic range and can cause toxicity if the dose is too high or if the patient has low potassium levels. A normal serum digoxin level is 0.5 to 2 ng/mL and a normal serum potassium level is 3.5 to 5 mEq/L. A low heart rate (less than 60 beats/min) is a sign of digoxin toxicity and the nurse should withhold the medication and report it to the provider. The nurse should also check the patient’s serum digoxin and potassium levels to determine if they are within normal limits.
C. Check the patient’s serum digoxin level.
Choice C is wrong because checking the patient’s serum digoxin level is not enough to prevent digoxin toxicity. The nurse should also check the patient’s serum potassium level and heart rate before giving digoxin.
D. Give an additional dose of digoxin.
Choice D is wrong because giving an additional dose of digoxin could cause a fatal overdose and lead to cardiac arrest. The nurse should never give more than the prescribed dose of digoxin without consulting the provider.
