A nurse is caring for a client in the ICU. The client's ECG monitor tracing reveals sinus bradycardia and ST-segment elevation. The client reports shortness of breath and feeling dizzy and faint. Which of the following medications should the nurse administer?

Digoxin

Sotalol

Atropine

Lidocaine

Answer and Explanation

The Correct Answer is C

Choice A reason: Digoxin is primarily used to treat atrial fibrillation and heart failure. It is not the first-line medication for sinus bradycardia with ST-segment elevation, as it can further slow down the heart rate.

Choice B reason: Sotalol is a beta-blocker and an antiarrhythmic medication that can be used to treat ventricular arrhythmias and maintain sinus rhythm in atrial fibrillation. However, it is not indicated for sinus bradycardia and could exacerbate the condition.

Choice C reason: Atropine is the medication of choice for symptomatic sinus bradycardia. It works by blocking the action of the vagus nerve on the heart, leading to an increased heart rate. Atropine can quickly reverse the symptoms of bradycardia, such as dizziness and shortness of breath.

Choice D reason: Lidocaine is an antiarrhythmic medication used to treat ventricular arrhythmias. While it can be used in acute settings, it is not the first choice for sinus bradycardia with ST-segment elevation.

Correct Answer is A

Explanation

Choice A reason : Displaying a monthly calendar can help orient a client with Alzheimer's disease to the date and assist with maintaining a sense of time, which can be beneficial in managing cognitive impairment.

Choice B reason: Providing plenty of stimulation can be overwhelming for clients with Alzheimer's disease. A calm and predictable environment is usually more beneficial.

Choice C reason: Keeping the room dark at night can promote sleep, but it is not the only consideration. A nightlight or low-level lighting can prevent falls if the client needs to get up during the night.

Choice D reason: Providing structured activities can help fill the client's time and provide a sense of purpose, but it should be tailored to the individual's abilities and preferences.

A. 1 cup white rice B. 1/2 cup nonfat yogurt C. 1 medium baked potato with skin D. 2 tbsp peanut butter

Correct Answer is A

Explanation

Choice A reason: White rice is considered a low-potassium food, making it a suitable option for someone with chronic kidney disease who needs to limit their potassium intake. One cup of cooked white rice contains approximately 54 mg of potassium, which is significantly lower than the other options listed.

Choice B reason: Nonfat yogurt can vary in potassium content, but on average, a 1/2 cup serving may contain around 200 to 300 mg of potassium. While it is a nutritious choice, it contains more potassium than white rice and should be consumed in moderation by individuals with potassium restrictions.

Choice C reason: A medium baked potato with skin is high in potassium, with one potato containing over 900 mg of potassium. This makes it an unsuitable choice for someone who needs to limit their potassium intake due to chronic kidney disease.

Choice D reason: Peanut butter contains a moderate amount of potassium. Two tablespoons of peanut butter can have around 150 to 200 mg of potassium. Although it's not as high in potassium as a baked potato, it still contains more potassium than white rice.
