An infant's axillary temperature is 35.9C (96.6F). The priority nursing action is to:

chart the normal axillary temperature.

recheck the infant's temperature rectally.

place the infant in a radiant warmer.

have the mother breastfeed the infant.

Answer and Explanation

The Correct Answer is C

Choice A reason:

Charting the normal axillary temperature is not the priority in this situation. The infant's temperature is subnormal, indicating hypothermia, which requires immediate intervention.

Choice B reason:

Rechecking the infant's temperature rectally may provide a more accurate reading, but it is not the priority action at this moment. The infant's low temperature indicates the need for immediate warming to prevent further complications.

Choice C reason:

Placing the infant in a radiant warmer is the priority nursing action. The axillary temperature of 35.9°C (96.6°F) is below the normal range for a newborn, which is around 36.5-37.5°C (97.7-99.5°F). Hypothermia in newborns can be dangerous and lead to respiratory distress, metabolic problems, and other complications. A radiant warmer provides a controlled heat source to warm the infant and stabilize their body temperature.

Choice D reason:

Having the mother breastfeed the infant may help provide warmth and comfort, but it is not the priority action. The immediate concern is to raise the infant's body temperature to a safe range using a radiant warmer.

Correct Answer is C

Explanation

Choice A reason:

While hypoglycemia (glucose <45 mg/dL) is concerning,58 mg/dLis within acceptable ranges for many institutions, especially in asymptomatic newborns. Monitoring is required, but it is less urgent than respiratory distress.

Choice B reason:

Respiratory rate of 78 breaths per minute is also within the normal range for a newborn, which typically ranges from 30 to 60 breaths per minute. Though respiratory rate is essential to assess, it does not take priority over other critical issues.

Choice C reason:

Newborns typically have a normal respiratory rate of30-60 breaths/minute. A rate of78indicatessignificant tachypnea, which could signal respiratory distress (e.g., transient tachypnea of the newborn, infection, or respiratory distress syndrome). Rapid breathing can lead to fatigue, hypoxia, or respiratory failure if not promptly addressed.

Choice D reason:

A glucose reading of 58 mg/dL is concerning in a newborn. Hypoglycemia (low blood glucose) can lead to serious complications if not promptly addressed. Newborns are particularly susceptible to hypoglycemia, and it requires immediate assessment and intervention.

A. Hyperbilirubinemia. B. Respiratory distress syndrome. C. Polycythemia. D. Transient tachypnea.

Correct Answer is A

Explanation

The correct answer is: a. Hyperbilirubinemia.

Choice A: Hyperbilirubinemia

Reason: Hyperbilirubinemia in newborns is often caused by the increased breakdown of red blood cells, which have a shorter lifespan in neonates. This breakdown produces bilirubin, a yellow pigment that can accumulate in the blood, leading to jaundice. The liver of a newborn is not fully mature and may not be able to process and excrete bilirubin efficiently, resulting in hyperbilirubinemia.

Choice B: Respiratory Distress Syndrome

Reason: Respiratory Distress Syndrome (RDS) is primarily caused by a deficiency of surfactant in the lungs, which is more common in premature infants. It is not directly related to the lifespan of red blood cells. Symptoms include rapid, shallow breathing and a bluish color due to lack of oxygen.

Choice C: Polycythemia

Reason: Polycythemia is characterized by an abnormally high concentration of red blood cells. It is often due to factors like delayed cord clamping or maternal diabetes, rather than the decreased lifespan of red blood cells. Polycythemia can lead to increased blood viscosity and complications such as sluggish blood flow.

Choice D: Transient Tachypnea

Reason: Transient Tachypnea of the Newborn (TTN) is a respiratory condition caused by delayed clearance of fetal lung fluid. It typically resolves within a few days and is not related to the lifespan of red blood cells. Symptoms include rapid breathing and grunting.
