A nurse will assess a client's temperature using a tympanic thermometer. Which action should the nurse include in the plan?

A. Lanugo is the fine hair covering a newborn’s body that helps protect the skin. Its presence or replacement with vellus hair is a normal developmental finding and does not directly affect the newborn’s risk for fluid loss.

B. Cradle cap, or seborrheic dermatitis, is a superficial scaling of the scalp. It is a cosmetic and dermatologic condition that does not increase fluid loss or compromise skin integrity systemically.

C. Vernix caseosa is a white, cheesy substance covering the skin at birth. It protects the skin from amniotic fluid in utero and assists with thermoregulation and moisture retention initially. Its presence at birth actually reduces the risk of fluid loss rather than increases it.

D. Newborns, especially preterm infants, have thin, immature, and highly permeable skin, which allows for increased transepidermal water loss. This places the infant at greatest risk for dehydration and fluid and electrolyte imbalances. The skin’s barrier function is underdeveloped, making thermoregulation and fluid retention more challenging. Newborns with this skin characteristic require careful monitoring of hydration status, fluid intake, and temperature control to prevent complications.

A. The client’s blood pressure improved from 90/56 (hypotension) to 120/80 (normal range). Hypotension can indicate systemic infection or early sepsis. A return to normal blood pressure suggests improved circulation and response to treatment. This is a significant sign of stabilization.

B. Oxygen saturation remained unchanged at 95% on room air. While this is within acceptable range, there was no improvement. It indicates stability but does not demonstrate change. Therefore, it does not reflect measurable improvement.

C. The respiratory rate decreased from 19 to 18 breaths per minute. Although both values are within normal limits (12–20 breaths per minute), infection and fever may cause mild tachypnea. The slight decrease reflects improved physiologic stress and stabilization.

D. The heart rate decreased from 110 (tachycardia) to 98 (within normal range). Fever and infection commonly cause tachycardia. A decrease toward normal indicates that the body is no longer under the same level of stress from infection. This is an important sign of recovery.

E. The temperature decreased from 102.3°F (39°C), which is clearly febrile, to 99.9°F (37.7°C), which is near normal. Fever is a hallmark sign of infection. A reduction in temperature is one of the strongest indicators that treatment is effective.

F. Pain improved from 6/10 to 2/10. Lower back pain can indicate kidney involvement (such as pyelonephritis). Decreasing pain suggests reduced inflammation and infection. Pain improvement is an important clinical indicator of recovery.
