Chapter 25- Thermoregulation Complete Answered & Explained) Exams_.

Origin: Chapter 25- Thermoregulation, 1 1.A nurse assesses an 82-year-old client who states, "That waiting room is so cold!" Which of the following systems should the nurse assess to determine the source of the clients sensations? (Select all that apply.) A) Bowel sounds B) Capillary refill time C) Oral temperature D) Respiratory rate E) Skin temperature Ans: B, C, E Feedback: The age-related changes that impact the older adult's response to cold include inefficient vasoconstriction, decreased cardiac output, diminished peripheral circulation, and delayed and diminished shivering. There is no indication of respiratory or bowel issues. Origin: Chapter 25- Thermoregulation, 2 2.A nurse monitors a group of older adults. Which of the following older adults is a high risk for functional consequences of altered thermoregulation? (Select all that apply.) A) 78-year-old adult with heart failure B) 75-year-old adult with a urinary tract infection C) 80-year-old adult with vascular-type dementia D) 71-year-old participant in a wellness center E) 72-year-old adult with peptic ulcer disease Ans: A, B, C Feedback: A healthy older adult in a comfortable environment will experience few, if any, functional consequences of altered thermoregulation. In the presence of any risk factor, however, hypothermia or heat-related illness may develop in an older adult. Even moderately adverse environmental temperatures can precipitate hypothermia or heat-related illness in an older adult, especially in the presence of additional predisposing factors, such as certain medications or pathologic conditions. Age-related changes, which can affect processes involved with heat loss or production, begin during the fifth decade, and their cumulative effects are experienced during the seventh or eighth decade. Origin: Chapter 25- Thermoregulation, 3 3.An 83-year-old puts on a sweatshirt and jacket preparing to go outside where it is currently 60°F. What interpretation should the nurse give to these actions? A) The client is experiencing a reaction to a medication. B) The client has decreased circulation due to heart failure. C) The client has a dementia and cannot make decisions. D) The client dresses to maintain an adequate internal temperature.
