A nurse is caring for a client who has atrial fibrillation and receives digoxin daily. Before administering this medication, which of the following actions should the nurse take?
Weigh the client.
Measure the client's blood pressure.
Measure the client's apical pulse.
Offer the client a light snack.
The Correct Answer is C
Choice A reason: Weighing the client is not a necessary action before administering digoxin, as it does not affect the dosage or effectiveness of the medication. Weighing the client may be important for monitoring fluid balance and edema, but it is not related to digoxin therapy.
Choice B reason: Measuring the client's blood pressure is not a necessary action before administering digoxin, as it does not affect the dosage or effectiveness of the medication. Digoxin is not a blood pressure-lowering medication, but a cardiac glycoside that increases the contractility and efficiency of the heart. Measuring the blood pressure may be important for monitoring hypertension, but it is not related to digoxin therapy.
Choice C reason: Measuring the client's apical pulse is a necessary action before administering digoxin, as it can help determine the safety and appropriateness of the medication. Digoxin can cause bradycardia (slow heart rate) as a side effect, which can be dangerous and symptomatic. The nurse should check the apical pulse for one full minute and withhold the medication if the pulse is below 60 beats per minute or above 100 beats per minute. The nurse should also report any abnormal or irregular rhythms to the provider.
Choice D reason: Offering the client a light snack is not a necessary action before administering digoxin, as it does not affect the absorption or effectiveness of the medication. Digoxin can be taken with or without food. Offering the client a light snack may be important for maintaining nutrition and hydration, but it is not related to digoxin therapy.

Correct Answer is B
Explanation
Choice A reason: Taking this medication with 8 ounces of water is not necessary. Sublingual nitroglycerin tablets are designed to dissolve under the tongue and be absorbed quickly into the bloodstream. Drinking water may interfere with the absorption and effectiveness of the medication.
Choice B reason: Taking one tablet at the first indication of chest pain is the correct instruction. Sublingual nitroglycerin tablets are used to relieve anginal pain by dilating the coronary arteries and improving blood flow to the heart. The client should place one tablet under the tongue as soon as chest pain occurs and wait for it to dissolve.
Choice C reason: Taking one tablet every 15 minutes during an acute attack is not the correct instruction. Sublingual nitroglycerin tablets have a short duration of action and may not provide adequate relief for a prolonged anginal attack. The client should follow the rule of three: take one tablet every 5 minutes for up to three doses. If the pain is not relieved after three doses, the client should call 911 or seek emergency medical attention.
Choice D reason: Taking this medication after each meal and at bedtime is not the correct instruction. Sublingual nitroglycerin tablets are not used for the prevention of angina. They are only used for the treatment of acute anginal episodes. Taking this medication regularly may cause tolerance and reduce its effectiveness.
Correct Answer is D
Explanation
Choice A reason: Reducing intake of potassium-rich foods is not necessary for clients taking hydrochlorothiazide, as this medication can cause hypokalemia (low potassium levels) due to increased potassium excretion in the urine. Clients may need to increase their intake of potassium-rich foods or take potassium supplements to prevent hypokalemia.
Choice B reason: Avoiding grapefruit juice is not necessary for clients taking hydrochlorothiazide, as this medication does not interact with grapefruit juice. Grapefruit juice can affect the metabolism of some other medications, such as statins, calcium channel blockers, and cyclosporine, by inhibiting the enzyme CYP3A4 in the liver.
Choice C reason: Taking this medication before bedtime is not advisable for clients taking hydrochlorothiazide, as this medication can cause increased urination and nocturia (nighttime urination). Clients should take this medication in the morning or at least 6 hours before bedtime to avoid disrupting their sleep.
Choice D reason: Monitoring for leg cramps is an important instruction for clients taking hydrochlorothiazide, as this medication can cause muscle cramps due to electrolyte imbalances, such as hypokalemia, hyponatremia (low sodium levels), or hypomagnesemia (low magnesium levels). Clients should report any signs of muscle cramps, weakness, or fatigue to their provider.
