Which thermoregulatory condition is an elderly person most at risk for?
Hypothermia.
Normothermia.
Hyperthermia.
Malignant hyperthermia.
The Correct Answer is A
Hypothermia is a condition where the body temperature drops below 35°C (95°F) and affects the normal functioning of the body. Elderly people are more at risk for hypothermia because they have a lower muscle mass, a decreased
shiver reflex, and lower immunity. They also tend to have a lower body temperature and may not develop fevers when they contract a viral or bacterial illness.
Choice B. Normothermia is wrong because it means having a normal body temperature, which is around 37°C (98.6°F).
Choice C. Hyperthermia is wrong because it means having a high body temperature, which is above 37.5°C (99.5°F).
Hyperthermia can be caused by heat exposure, infection, inflammation, or certain medications.
Choice D. Malignant hyperthermia is wrong because it is a rare genetic disorder that causes a severe reaction to certain anesthetics or muscle relaxants.
It is not related to thermoregulation in elderly people.

Correct Answer is C
Explanation
This action is intended to prevent a sentinel event, which is a patient safety event that results in death, permanent harm, or severe temporary harm. A sentinel event is a serious adverse event that signals the need for immediate investigation and response. Removing the wrong arm would be a devastating and irreversible outcome for the patient and the health care provider.
Choice A is wrong because the lack of healing of the stump is not a sentinel event. It is a possible complication of amputation that may be related to the natural course of the patient’s illness or underlying condition.
Choice B is wrong because ineffective control of the client’s pain is not a sentinel event. It is a quality of care issue that may affect the patient’s comfort and recovery, but it does not result in death, permanent harm, or severe temporary harm.
Choice D is wrong because the client being mildly sedated is not a sentinel event. It is a level of anesthesia that may be appropriate for some types of surgery, but it does not result in death, permanent harm, or severe temporary harm.
Correct Answer is A
Explanation
Watching television until falling asleep at night is a poor sleep habit because it can interfere with the body’s natural sleep-wake cycle and make it harder to fall asleep and stay asleep. Television can also expose the eyes to bright light and stimulating or stressful content, which can affect the production of melatonin, a hormone that regulates sleep.
Choice B is wrong because having a small snack and taking a bath before going to bed each day are good sleep habits that can promote relaxation and sleep quality.
Choice C is wrong because not taking naps throughout the day is a good sleep habit that can help maintain a consistent sleep schedule and avoid disrupting the night-time sleep.
Choice D is wrong because going to bed and getting up at the same times each day is a good sleep habit that can reinforce the body’s circadian rhythm and make it easier to fall asleep and wake up.
