Which thermoregulatory condition is an elderly person most at risk for?

A.

Hypothermia.

B.

Normothermia.

C.

Hyperthermia.

D.

Malignant hyperthermia.

Answer and Explanation

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

Pursed-lip breathing is a technique that helps to slow down the breathing rate and keep the airways open longer. This improves gas exchange and reduces the work of breathing. Pursed-lip breathing also helps to prevent air trapping and hyperinflation of the lungs, which are common complications of COPD.

Choice B is wrong because laying down for 1 hour after meals can increase the pressure on the diaphragm and make breathing more difficult. It can also increase the risk of aspiration and reflux.

Choice C is wrong because restricting the client’s fluid intake to less than 1 L/day can lead to dehydration and thickening of secretions, which can obstruct the airways and impair gas exchange. Fluid intake should be adequate to maintain hydration and thin secretions.

Choice D is wrong because using the upper chest for respiration is a sign of inefficient breathing and respiratory distress.

It can increase the oxygen demand and cause fatigue. The client should be encouraged to use the diaphragm and abdominal muscles for respiration, which are more efficient and reduce the work of breathing.

Normal ranges for oxygen saturation are 95% to 100%, for arterial blood gas pH are 7.35 to 7.45, for PaCO2 are 35 to 45 mmHg, for PaO2 are 80 to 100 mmHg, and for HCO3 are 22 to 26 mEq/L.

Correct Answer is A

Explanation

The SBAR is used to organize and standardize communication between members of the health care team about a patient’s condition. It is an acronym for Situation, Background, Assessment, and Recommendation.

Choice B is wrong because the SBAR is not used to help Physical Therapy determine the client’s abilities.

Physical Therapy may use other tools or methods to assess the client’s functional status.

Choice C is wrong because the SBAR is not used to help physicians with diagnoses.

The SBAR is a communication tool, not a diagnostic tool.

Physicians may use other sources of information or tests to make diagnoses.

Choice D is wrong because the SBAR is not used to educate clients about their disease processes.

The SBAR is a tool for interprofessional communication, not for patient education.

Clients may receive education from other sources or materials.
