A nurse is caring for an 83-year-old client who asks for a warm blanket despite the room temperature being 80°F. The nurse understands that which of the following physiological changes experienced by older adults makes it more difficult for them maintain their body temperature?
Decline in estrogen production
Increased blood pressure
Decreased muscle strength and tone
Decreased subcutaneous fat
The Correct Answer is D
A. Estrogen's role in temperature regulation is not as significant as other factors in the context of aging and body temperature maintenance.
B. Increased blood pressure itself does not directly influence the ability to maintain body temperature. While hypertension can have various effects on cardiovascular health, it is not a primary factor in the regulation of body temperature in older adults.
C. Decreased muscle strength and tone are significant factors affecting temperature regulation. Muscle activity generates heat, and a decline in muscle mass and strength can impair the body’s ability to generate and maintain adequate warmth.
D. Decreased subcutaneous fat is a key factor in temperature regulation. Subcutaneous fat acts as an insulator, helping to retain body heat. As people age, they often experience a decrease in subcutaneous fat, which reduces their ability to insulate and maintain body heat effectively.

Correct Answer is ["B","E"]
Explanation
A. Total bedrest is generally not recommended. It is important to balance rest with gentle movement to maintain joint function and prevent stiffness. Instead of complete bedrest, promoting periods of rest
while allowing for limited activity as tolerated is more appropriate. Avoiding use of affected joints may be beneficial during acute inflammation but complete immobilization can lead to muscle atrophy and joint stiffness.
B. Applying warm compresses to affected joints can help relieve stiffness and pain associated with RA. Warmth can improve blood flow and reduce muscle tension around the joints. This intervention is typically beneficial during periods of stiffness and can help increase comfort. However, cold compresses may also be used during acute inflammation to reduce swelling.
C. Placing pillows to keep the neck in a flexed position is not advisable for RA patients. It can cause discomfort and potentially worsen joint and muscle issues. Proper positioning should support natural body alignment, and patients should be encouraged to maintain a neutral neck position to avoid additional strain.
D. Continuous cardiac monitoring is not a routine intervention for RA exacerbations unless there is an indication of cardiac involvement or complications. RA itself does not typically require continuous cardiac monitoring.
E. Methylprednisolone is a corticosteroid used to reduce inflammation and manage RA symptoms during flares. Administering it as ordered is an appropriate intervention to control inflammation and alleviate symptoms.
Correct Answer is D
Explanation
A. MS is an autoimmune disorder affecting the central nervous system, not the kidneys.
B. MG is an autoimmune disorder affecting the neuromuscular junction, not the kidneys.
C. GBS is an autoimmune disorder affecting the peripheral nervous system, not the kidneys.
D. SLE is a systemic autoimmune disorder that can affect multiple organs, including the kidneys. Glomerulonephritis is a common complication of SLE.
