Which of the following is most important for the nurse to include with calcium channel blockers?

Always check your apical heart rate before taking this medication

Calcium channel blockers may cause increased blood pressure, so immediately report blurred vision

These medications are best taken at night to reduce cholesterol

Do not drink grapefruit juice while on this medication

Answer and Explanation

The Correct Answer is D

Choice A reason: This choice is incorrect because checking the apical heart rate before taking calcium channel blockers is not necessary for most patients. Calcium channel blockers are a group of medications that relax and widen blood vessels, lower blood pressure, and slow the heart rate. They are used to treat conditions such as hypertension, angina, and arrhythmias. The nurse should check the apical heart rate only if the patient has a history of bradycardia (slow heart rate) or heart block (a problem with the electrical conduction of the heart).

Choice B reason: This choice is incorrect because calcium channel blockers do not cause increased blood pressure, but rather lower it. Blurred vision is not a common side effect of calcium channel blockers, and it may indicate other problems, such as eye infection, glaucoma, or stroke. The nurse should instruct the patient to report any changes in vision, but not to associate them with calcium channel blockers.

Choice C reason: This choice is incorrect because calcium channel blockers do not affect cholesterol levels, and the time of day they are taken does not matter. Cholesterol is a type of fat that circulates in the blood and can build up in the arteries, causing atherosclerosis (hardening and narrowing of the arteries). Cholesterol levels are influenced by diet, exercise, genetics, and other medications, such as statins. The nurse should advise the patient to follow a healthy lifestyle and take any prescribed medications for cholesterol control.

Choice D reason: This choice is correct because grapefruit juice can interact with some calcium channel blockers, such as nifedipine, verapamil, and diltiazem, and increase their blood levels and effects. This can cause serious side effects, such as low blood pressure, dizziness, headache, flushing, and edema (swelling). The nurse should warn the patient to avoid grapefruit juice and any products that contain grapefruit while taking calcium channel blockers.

Correct Answer is ["10"]

Explanation

The nurse needs to administer 775 mg of amoxicillin. The available amoxicillin oral suspension is 400 mg/5 mL, which means there are 400 mg of amoxicillin in every 5 mL of the suspension.

Therefore, for a 775 mg dose, the nurse should administer:

775 mg/(400 mg/5mL) = 9.6875 mL of the suspension

So, the nurse should administer approximately 10 mL (rounded to the nearest whole number).

A. Atenolol B. Captopril C. Warfarin D. Glipizide

Correct Answer is A

Explanation

Choice A reason: Atenolol is a beta blocker that lowers blood pressure and heart rate. The nurse should hold atenolol for this client because the client's heart rate is already low (52 beats per minute), and giving atenolol could cause bradycardia (slow heart rate), which can lead to dizziness, fainting, or heart failure. The nurse should notify the provider and monitor the client's vital signs and cardiac rhythm.

Choice B reason: Captopril is an ACE inhibitor that lowers blood pressure and prevents kidney damage. The nurse should not hold captopril for this client because the client's blood pressure is still high (138/90 mmHg), and captopril could help lower it to the target range. The nurse should administer captopril as prescribed and monitor the client's blood pressure and renal function.

Choice C reason: Warfarin is an anticoagulant that prevents blood clots and reduces the risk of stroke. The nurse should not hold warfarin for this client because the client's INR (a measure of blood clotting time) is within the therapeutic range (2.0 to 3.0), and warfarin could help prevent post-operative complications such as deep vein thrombosis or pulmonary embolism. The nurse should administer warfarin as prescribed and monitor the client's INR and bleeding signs.

Choice D reason: Glipizide is not a medication for this client. Glipizide is an oral hypoglycemic agent that lowers blood sugar levels in people with diabetes. This client does not have diabetes and does not need glipizide. The nurse should check the medication order and the client's medical history and clarify any discrepancies with the provider.
