Order: Digoxin 0.25 mg
On hand: 250 mcg tablets
How many tablets will the nurse give?
No answer is provided
1
No answer is too low
No answer is too high
No answer is too high
The Correct Answer is B
This choice is correct because it is the result of dividing the ordered dose (0.25 mg) by the strength of the tablet (250 mcg or 0.25 mg). The formula for calculating the number of tablets to be given is:
Tablets = Dose/ Strength
Therefore, the number of tablets to be given is:
Tablets = 0.25 mg/250 mcg = 0.25 mg/0.25 mg = 1

Correct Answer is D
Explanation
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 ["4.5"]
Explanation
To calculate the dose of ondansetron that the nurse should administer, we can follow these steps:
Convert the client's weight from pounds to kilograms:
132 lb ÷ 2.2 = 60 kg
Calculate the dose of ondansetron:
0.15 mg/kg × 60 kg = 9 mg
Determine the volume of ondansetron needed using the available concentration:
9 mg ÷ 2 mg/mL = 4.5 mL
Rounding to the nearest tenth, the nurse should administer 4.5 mL of ondansetron via IV.
