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.

Explanation
The Nurse Practice Act is a law that outlines the legal scope of practice for nursing in each state. It defines the roles, functions, responsibilities and activities that a nurse is educated, competent and authorized to perform. The Nurse Practice Act also establishes the regulatory bodies that create and implement rules and regulations to protect the public.
Choice B. Nursing process is wrong because it is a systematic method of providing nursing care, not a legal document that defines the scope of practice.
Choice C. Code of Ethics is wrong because it is a set of principles that guide the moral and professional conduct of nurses, not a legal document that defines the scope of practice.
Choice D. Facility policies and procedures are wrong because they are specific guidelines for each healthcare organization, not a legal document that defines the scope of practice.
Correct Answer is C
Explanation
This nursing diagnosis is typically not associated with anemia because anemia does not cause dehydration or loss of body fluids. Anemia is a condition in which the hemoglobin concentration or the number of red blood cells is lower than normal, resulting in decreased oxygen delivery to the tissues.
Choice A. Ineffective tissue perfusion is wrong because anemia can impair tissue perfusion by reducing the oxygen-carrying capacity of the blood.
Choice B. Activity intolerance is wrong because anemia can cause fatigue, weakness, and dyspnea on exertion due to inadequate oxygen supply to the muscles.
Choice D. Risk for decreased cardiac output is wrong because anemia can increase the risk of cardiac complications such as tachycardia, palpitations, angina, and heart failure due to increased cardiac workload and demand for oxygen.
Normal ranges for hemoglobin are 13.5 to 17.5 g/dL for men and 12 to 15.5 g/dL for women; normal ranges for hematocrit are 38.8 to 50% for men and 34.9 to 44.5% for women; normal ranges for red blood cell count are 4.7 to 6.1 million/mm3 for men and 4.2 to 5.4 million/mm3 for women; normal ranges for reticulocyte count are 0.5 to 1.5% of red blood cells.
