A nurse is teaching a client who has angina pectoris about starting therapy with SL nitroglycerin tablets. The nurse should include which of the following instructions regarding how to take the medication?

Take this medication after each meal and at bedtime.

Take one tablet every 15 min during an acute atack.

Take this medication with 8 ounces of water.

Take one tablet at the first indication of chest pain.

Answer and Explanation

The Correct Answer is D

Taking one tablet at the first indication of chest pain is the correct way to use SL nitroglycerin tablets, as they are fast- acting and can relieve anginal symptoms within minutes. The client should place the tablet under the tongue and let it dissolve.

Taking this medication after each meal and at bedtime is not appropriate, as SL nitroglycerin tablets are not meant for routine or prophylactic use, but only for acute episodes of angina.

Taking one tablet every 15 min during an acute attack is not correct, as the client should not exceed three doses in 15 min. If the pain is not relieved after three doses, the client should seek emergency medical attention.

Taking this medication with 8 ounces of water is not necessary, as SL nitroglycerin tablets do not need to be swallowed or washed down with water. They should be dissolved under the tongue for optimal absorption.

Correct Answer is B

Explanation

Planning to slow down if tired the day after exercising is a statement that indicates the client understands the importance of pacing activities and avoiding overexertion, which can worsen heart failure symptoms.

a. "I should use naproxen to manage discomfort." is not correct, as naproxen is a nonsteroidal anti-inﬂammatory drug (NSAID) that can cause ﬂuid retention, increase blood pressure, and worsen heart failure. The client should avoid NSAIDs and use other analgesics, such as acetaminophen, unless contraindicated.

c. "I will read food labels and limit my sodium to 4 grams per day." is not appropriate, as 4 grams of sodium per day is too high for a client who has congestive heart failure. The client should limit sodium intake to 2 grams or less per day, as sodium can cause ﬂuid retention and increase the workload of the heart.

d. "I will take my diuretic before sleep and drink ﬂuids during the day." is not advisable, as taking a diuretic before sleep can cause nocturia and disrupt the sleep cycle, which can aﬀect the quality of life and cardiac function. The

A. Administer an anticholinesterase medication. B. Instruct the client to perform the pursed lip breathing. C. Prepare to administer a vasoconstrictor. D. Prepare the client for mechanical ventilation.

Correct Answer is D

Explanation

Choice A reason:

Administering an anticholinesterase medication is not the primary intervention during a myasthenic crisis. While these medications can improve muscle strength in myasthenia gravis, they are not sufficient in the event of a crisis.

Choice B reason:

Pursed lip breathing is a technique used to manage dyspnea but is not adequate for the acute management of a myasthenic crisis, which can involve respiratory muscle paralysis.

Choice C reason:

Vasoconstrictors are not used in the treatment of myasthenic crisis. This condition is not related to vascular issues but to neuromuscular transmission failure leading to respiratory failure.

Choice D reason:

Mechanical ventilation is the correct intervention as it provides the necessary respiratory support when the patient's respiratory muscles are too weak to maintain adequate ventilation.
