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.

This is an example of secondary prevention, which is the action taken to stop the progress of the disease at the initial stage and prevent complications. An echocardiogram can help diagnose the severity and cause of heart failure and guide the treatment plan.
A client who has a family history of breast cancer and is scheduled for a mammogram is an example of secondary prevention. Secondary prevention is early detection of a disease before it progresses. Secondary prevention can include screenings and other forms of diagnostic tests.
This is an example of tertiary prevention, which is the action taken to stop the progress of the disease at the initial stage and prevent complication. An echocardiogram can help diagnose the severity and cause of heart failure and guide the treatment plan.
Choice C is wrong because it is not an example of any level of prevention.
A client who is asymptomatic is not scheduled for a series of tests because there is no indication of any disease or risk factor.
Choice D is wrong because it is an example of primary prevention, which is the action taken to prevent the development of disease.

Correct Answer is D
Explanation
A client with chronic bronchitis is expected to have a cough that produces sputum for at least 3 months during two successive years. This is due to the hyperplasia of mucous glands and bronchial wall inflammation that occur in chronic bronchitis.
Choice A is wrong because SpO2 >92% is not a specific finding for chronic bronchitis.
SpO2 is a measure of oxygen saturation in the blood and can vary depending on many factors, such as altitude, smoking, and lung diseases. SpO2 may be lower than normal in COPD patients due to airflow obstruction and impaired gas exchange.
Choice B is wrong because underweight is not a typical finding for chronic bronchitis.
Underweight may be more associated with emphysema, which is another component of COPD that involves the destruction of alveolar walls and enlargement of air spaces. Emphysema can cause weight loss due to increased work of breathing and decreased appetite.
Choice C is wrong because bradypnea is not a common finding for chronic bronchitis.
Bradypnea is abnormally slow breathing rate and can be caused by various conditions, such as brain injury, drug overdose, or sleep apnea. Chronic bronchitis usually causes tachypnea, which is abnormally fast breathing rate, due to hypoxia and hypercapnia.
