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 A
Explanation
This is because hypokalemia (low potassium level in the blood) can cause abnormal heart rhythms (arrhythmia) that can be life-threatening and require urgent medical attention. A cardiac monitor can help detect and treat any arrhythmia that may occur.
Choice B is wrong because administering a laxative can worsen hypokalemia by causing more potassium loss through the digestive tract. Laxative use is one of the possible causes of hypokalemia.
Choice C is wrong because placing the client on seizure precautions is not a priority intervention for hypokalemia. Seizures are not a common symptom of hypokalemia, although muscle weakness and cramps may occur.
Choice D is wrong because restricting high potassium foods is not a priority intervention for hypokalemia. In fact, increasing potassium intake through foods or supplements may be helpful in less serious cases of hypokalemia. However, this should be done according to the doctor’s recommendation and with careful monitoring of blood potassium levels.
Normal blood potassium levels for an adult range from 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L) can be life threatening.
Correct Answer is C
Explanation
According to Mayo Clinic, physical therapy and exercises can improve strength, flexibility and stamina for people with fibromyalgia.
Low-impact aerobics, such as swimming or biking, are recommended as they are less likely to cause muscle soreness or injury.
Choice A is wrong because antidepressant medications can help ease the pain and fatigue associated with fibromyalgia.
They are often prescribed as part of the treatment plan.
Choice B is wrong because physical manifestations of the disease do not become progressively worse despite treatment.
Fibromyalgia is a chronic condition, but it does not damage the joints, muscles or organs.
Choice D is wrong because narcotic analgesia will not be used for long-term pain control. Opioid medications can cause significant side effects and dependence and will worsen the pain over time.
They are not recommended for fibromyalgia treatment.
