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.

Answer and Explanation

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 C

Explanation

Choice A reason: A headache is not likely due to the anxiety about the chest pain, as anxiety usually causes other symptoms, such as palpitations, sweating, or trembling. A headache is more likely related to the vasodilating action of nitroglycerin, which causes increased blood flow to the brain.

Choice B reason: A headache does not indicate tolerance to the medication, as tolerance usually manifests as a reduced effect of the medication on relieving chest pain. A headache is more likely a sign of the medication's potency, as it indicates that the nitroglycerin is reaching the systemic circulation.

Choice C reason: A headache is an expected adverse effect of the medication, as nitroglycerin causes vasodilation of the cerebral vessels, which can result in increased intracranial pressure and pain. A headache is usually mild and transient, and can be relieved by taking analgesics, such as acetaminophen.

Choice D reason: A headache is not an indication of an allergy to the medication, as an allergic reaction usually causes other symptoms, such as rash, itching, swelling, or difficulty breathing. A headache is more likely a pharmacological effect of the medication, rather than an immunological response.

A. Inject the medication into the abdomen above the level of the iliac crest. B. Massage the injection site after administration of the medication. C. Use a 1-inch needle to inject the medication. D. Use a 22-gauge needle to inject the medication.

Correct Answer is A

Explanation

Choice A reason: Injecting the medication into the abdomen above the level of the iliac crest is the correct action. This is the preferred site for heparin administration, as it has fewer blood vessels and nerves, and allows for better absorption of the medication. The nurse should avoid the area around the umbilicus, as it may have increased bleeding and bruising.

Choice B reason: Massaging the injection site after administration of the medication is not the correct action. This may cause hematoma formation, tissue irritation, and reduced effectiveness of the medication. The nurse should apply gentle pressure to the injection site for 1 to 2 minutes after administration.

Choice C reason: Using a 1-inch needle to inject the medication is not the correct action. This may cause pain, tissue damage, and bleeding. The nurse should use a 25- to 28-gauge needle that is 3/8 to 5/8 inch long to inject the medication.

Choice D reason: Using a 22-gauge needle to inject the medication is not the correct action. This may cause pain, tissue damage, and bleeding. The nurse should use a 25- to 28-gauge needle that is 3/8 to 5/8 inch long to inject the medication.
