Newborns and young infants tend to experience temperature fluctuations because they have a three times greater surface area relative to their mass from which heat is lost and a metabolic rate twice that of adults. Infants and older adults have difficulty maintaining normal body temperature because they have limited, not large, amounts of subcutaneous white adipocytes, fat cells that provide heat insulation and cushioning of internal structures. The ability of both young and old to shiver and perspire also may be inadequate, putting them at risk for abnormally low or high body temperatures. Infants and older adults are less able to independently forestall or reverse heat loss or gain than are other clients. However, the main cause for fluctuations in infants' body temperature is because they have a three times greater surface area relative to their mass from which heat is lost and a metabolic rate twice that of adults.

The nurse should use a straight catheter to collect a sterile urine specimen from the client. A straight catheter is a urine drainage tube inserted but not left in place. It drains urine temporarily or provides a sterile urine specimen. Condom catheters are helpful for clients with urinary incontinence receiving care at home because they are easy to apply. A urinary bag is more often used to collect urine specimens from infants. A retention catheter, also called an indwelling catheter, is left in place for a period of time.
