A nurse is providing teaching to a client who is to start furosemide therapy for heart failure. Which of the following statements indicates that the client understands a potential adverse effect of this medication?

"I'm going to include more cantaloupe in my diet."

"I will check my pulse before I take the medication."

"I will try to limit foods that contain salt."

"I'll check my blood pressure so it doesn't get too high."

Answer and Explanation

The Correct Answer is A

Choice A reason: Including more cantaloupe in the diet is a good practice for a client on furosemide therapy. Cantaloupe is high in potassium, and furosemide can cause hypokalemia (low potassium levels) as it is a potent diuretic that increases urine production and the excretion of various electrolytes, including potassium. Therefore, consuming foods rich in potassium can help counteract this potential adverse effect.

Choice B reason: Checking the pulse before taking the medication is a general safety measure but does not directly relate to a specific adverse effect of furosemide. While it's important to monitor heart rate, especially in clients with heart failure, this statement does not reflect an understanding of the adverse effects related to furosemide.

Choice C reason: Trying to limit foods that contain salt is an appropriate action for a client with heart failure but is not directly related to an adverse effect of furosemide. Reducing salt intake can help manage heart failure by preventing fluid retention; however, it does not address the specific adverse effects of furosemide therapy.

Choice D reason: Checking blood pressure to ensure it doesn't get too high is important for clients with heart failure but does not indicate an understanding of the adverse effects of furosemide. Furosemide is used to reduce excess fluid in the body, which can lower blood pressure, not increase it. This statement does not reflect an understanding of furosemide's potential to cause electrolyte imbalances.

Correct Answer is B

Explanation

Choice A reason: The statement that "the spacer should make a whistling sound as you inhale" is not accurate. A whistling sound from the spacer may indicate that the air is being inhaled too quickly and that the user needs to slow down. The purpose of the spacer is to hold the medication released from the inhaler so that it can be inhaled more easily and effectively into the lungs, not to produce a whistling sound.

Choice B reason: Holding one's breath for 10 seconds after inhaling the medication allows for better deposition of the medication in the lungs. This pause gives the medication time to settle in the airways rather than being exhaled too quickly. It is a recommended practice to maximize the effectiveness of the inhaled medication.

Choice C reason: Cleaning the spacer is important to ensure that it works correctly and is free of any residue or debris that could obstruct the medication's path. However, the instruction to "clean the spacer daily with cold water" is incomplete. After rinsing with cold water, the spacer should be left to air dry without rinsing or wiping, as this can create static that affects medication delivery.

Choice D reason: Waiting 30 seconds between puffs is recommended to allow the user to breathe normally for a short period and to prepare for the next dose of medication. This time interval helps to ensure that the second puff is not rushed and that the medication from the first puff has had time to act.

A. Two tablets PO (by mouth) every 15 minutes. B. One tablet SL (sublingual) every 15 minutes, up to 5 times. C. One tablet PO (by mouth) every one hour, up to 5 times. D. One tablet SL (sublingual) every 5 minutes, up to 3 times.

Correct Answer is D

Explanation

Choice A reason: Taking two tablets PO every 15 minutes is not the standard protocol for nitroglycerin administration for chest pain. This method could lead to an overdose and significant hypotension (low blood pressure), which can be dangerous.

Choice B reason: One tablet SL every 15 minutes, up to 5 times, is also not the standard protocol. While sublingual administration is correct, the frequency and the total number of doses are higher than recommended, which could result in adverse effects such as headache, dizziness, or a severe drop in blood pressure.

Choice C reason: One tablet PO every one hour, up to 5 times, is not a recommended method for acute chest pain relief from angina. Oral administration does not provide the rapid onset of action required for acute angina relief.

Choice D reason: One tablet SL every 5 minutes, up to 3 times, is the correct protocol for nitroglycerin administration when experiencing chest pain due to angina. If pain persists after the first dose, the patient can take a second dose after 5 minutes, and if needed, a third dose after another 5 minutes. If chest pain continues after three doses in 15 minutes, emergency medical help should be sought immediately.
