Which assessment made by the nurse is a major sign of renal changes related to age?

A. Decreased impulse conduction speed

Aging causes slower nerve conduction due to loss of myelin and reduced neurotransmitter activity, leading to slower reflexes and response times.

B. Atherosclerosis and decreased cellular respiration

These factors affect circulation and energy production but are not primary causes of slowed neurologic responses.

C. Inadequate tissue oxygenation

Can affect brain function acutely, but it's not the main cause of chronic, gradual slowing in the elderly.

D. Loss of neurons in the brain

While this occurs with aging, slowed reflexes are more specifically linked to nerve impulse transmission rather than neuron quantity alone.

A. Obtain an order from the primary caregiver for a sedative

Not appropriate as a first step; sedatives in the elderly increase the risk of falls and confusion and should only be used after thorough evaluation.

B. Ask the patient if he is sleeping well at night

This helps identify underlying sleep disturbances, such as nocturia or insomnia, which may be the cause of daytime fatigue.

C. Tell the patient that he cannot take any more naps

Restricting naps without assessing the cause of tiredness is inappropriate and may worsen fatigue.

D. Plan activities to keep the patient awake during the day

May be helpful after assessing nighttime sleep habits and determining the cause of daytime drowsiness.
