Common source of radiant heatloss includes cool incubator walls andwindows. Low room humidity promotesevaporative heat loss. When the skin directlycontacts a cooler object, such as a cold weightscale, conductive heat loss may occur. A coolroom temperature may lead to convective heatloss.26. Answer D. Bethanechol will increase GImotility, which may cause nausea, belching,vomiting, intestinal cramps, and diarrhea.Peristalsis is increased rather than decreased.With high doses of bethanechol, cardiovascularresponses may include vasodilation, decreasedcardiac rate, and decreased force of cardiaccontraction, which may cause hypotension.Salivation or sweating may gently increase.27.
