Answer to Question 1
B
Because antipsychotic medications potentially impair the body's thermoregulatory ability, the nurse instructs an older adult who takes an antipsychotic agent such as chlorpromazine to avoid caffeinated beverages because they contribute to dehydration. This man is at high risk for organ damage as a result of hyperthermia from mild elevations in the environmental temperature; therefore he must avoid dehydration, stay in cool temperatures, keep out of direct sunlight, and alert people around him and caregivers to monitor his temperature carefully and to be prepared to provide cooling sponge baths, cool liquids, and other measures to reduce his temperature quickly. The nurse instructs all older adults to avoid eating biscuits and gravy because these items have an excessively high fat content. Whole grain bread is a healthy food item to choose. Mixed green salad is a healthy food item to choose.
