An older man in a cardiac rehabilitation exercise class refuses to participate in the cool-down phase of the activity. Consequently, 2 minutes later, he passes out but quickly regains consciousness. Which instruction does the nurse include in client teaching to reinforce the importance of cooling down after exercising to this man?

Baroreceptor function diminishes with age.

Sensory perception diminishes with age.

Cardiac output diminishes with age.

Mobility capacity decreases with age.

Answer and Explanation

The Correct Answer is A

Choice A reason: This is the correct answer because baroreceptor function diminishes with age, and this can affect the regulation of blood pressure and heart rate. Baroreceptors are sensory receptors that detect changes in blood pressure and send signals to the brain to adjust the heart rate and blood vessel tone accordingly. When a person exercises, the blood pressure and heart rate increase to meet the increased oxygen demand of the muscles. When a person stops exercising, the blood pressure and heart rate should decrease gradually to return to the resting state. However, if a person does not cool down properly after exercising, the blood pressure and heart rate can drop suddenly, causing dizziness, fainting, or cardiac arrhythmias. This is especially true for older adults, whose baroreceptors are less sensitive and responsive to blood pressure changes. Therefore, the nurse should instruct the older man to cool down after exercising to prevent these complications.

Choice B reason: This is incorrect because sensory perception diminishes with age, but this is not related to the importance of cooling down after exercising. Sensory perception is the ability to perceive stimuli from the environment, such as sight, hearing, touch, smell, or taste. Sensory perception can decline with age due to various factors, such as age-related changes in the sensory organs, nerve damage, or diseases. This can affect the quality of life, communication, and safety of older adults, but it does not explain why cooling down after exercising is important.

Choice C reason: This is incorrect because cardiac output diminishes with age, but this is not related to the importance of cooling down after exercising. Cardiac output is the amount of blood pumped by the heart per minute, and it depends on the heart rate and the stroke volume. Cardiac output can decline with age due to various factors, such as age-related changes in the heart muscle, valves, or arteries, or diseases. This can affect the ability of the heart to meet the oxygen demand of the body, especially during exercise, but it does not explain why cooling down after exercising is important.

Choice D reason: This is incorrect because mobility capacity decreases with age, but this is not related to the importance of cooling down after exercising. Mobility capacity is the ability to move and perform physical activities, such as walking, climbing stairs, or lifting objects. Mobility capacity can decrease with age due to various factors, such as age-related changes in the muscles, bones, or joints, or diseases. This can affect the functional status, independence, and well-being of older adults, but it does not explain why cooling down after exercising is important.

Correct Answer is C

Explanation

Choice A reason: A nasogastric tube may be necessary for some patients with dysphagia, which is difficulty swallowing, but not for dysarthria, which is difficulty speaking.

Choice B reason: Stems from severe rheumatoid arthritis is false because dysarthria is caused by damage to the nerves or muscles that control speech, not by inflammation of the joints.

Choice C reason: Physical therapy can be beneficial is true because dysarthria can be improved by exercises that strengthen the speech muscles and improve coordination.

Choice D reason: Can affect the balance is false because dysarthria does not affect the vestibular system, which is responsible for balance and spatial orientation.

A. Call 9-11. B. Determine if the client has a history of migraine headaches. C. Give the client a dose of acetaminophen. D. Assure the client the symptoms will resolve within 24 hours.

Correct Answer is A

Explanation

Choice A reason: This action is correct because the client is showing signs of a possible stroke, such as a severe headache and numbness in one side of the body. The nurse should call 9-11 immediately to get the client to the nearest hospital for urgent evaluation and treatment. The nurse should also monitor the client's vital signs, neurological status, and airway until help arrives.

Choice B reason: This action is incorrect because the client's headache and numbness are not likely to be caused by a migraine, but by a stroke. The nurse should not waste time asking about the client's history of headaches, but rather act quickly to get the client to the hospital. The nurse should also not assume that the client's symptoms are benign or familiar, but rather treat them as an emergency.

Choice C reason: This action is incorrect because the client's headache and numbness are not likely to be relieved by acetaminophen, but by a stroke. The nurse should not give the client any medication without a doctor's order, especially if the client has a history of TIA or stroke. The nurse should also not delay calling 9-11 by administering medication, as every minute counts in saving the client's brain cells.

Choice D reason: This action is incorrect because the client's headache and numbness are not likely to resolve within 24 hours, but by a stroke. The nurse should not reassure the client that the symptoms are temporary or harmless, but rather alert the client that they are signs of a serious condition. The nurse should also not delay calling 9-11 by providing false comfort, as the client's condition may worsen rapidly.
