A nurse is performing a head-to-toe assessment on a newborn. Which of the following actions should the nurse take to prevent heat loss through conduction?

Conduct the assessment before drying the newborn.

Check the newborn's rectal temperature every hr.

Place the newborn in an open crib for the initial assessment.

Cover scale with warm blankets when weighing the newborn.

Answer and Explanation

The Correct Answer is D

Rationale:
A. Conduct the assessment before drying the newborn: Performing the assessment before drying exposes the newborn’s wet skin to cooler air and surfaces, increasing heat loss through evaporation, not conduction. The newborn should always be thoroughly dried immediately after birth to conserve body heat.

B. Check the newborn's rectal temperature every hr: Frequent temperature monitoring does not prevent heat loss; it only identifies hypothermia after it occurs. Additionally, rectal temperature measurement may cause mucosal injury and is not routinely recommended for newborns.

C. Place the newborn in an open crib for the initial assessment: Placing the newborn in an open crib exposes the infant to cooler air and surfaces, increasing heat loss through convection and conduction. The initial assessment should occur under a radiant warmer to maintain thermal stability.

D. Cover scale with warm blankets when weighing the newborn: Covering the scale prevents conduction heat loss, which occurs when the newborn’s skin comes into contact with cold surfaces. Using a warm blanket or pad ensures the infant’s body heat is preserved during weighing or handling.

Correct Answer is C

Explanation

Rationale:
A. Hypovolemia: Hypovolemia causes a decrease in PAWP due to reduced circulating blood volume and inadequate venous return to the heart. A low PAWP reflects decreased left ventricular preload, not an elevated value.

B. Hypotension: Hypotension alone does not directly increase PAWP. In fact, low blood pressure often accompanies decreased cardiac filling pressures. Elevated PAWP typically occurs with fluid overload or impaired ventricular function rather than simple hypotension.

C. Left ventricular failure: An elevated PAWP indicates increased left-sided heart pressures due to ineffective left ventricular pumping. Blood backs up into the pulmonary circulation, leading to pulmonary congestion and edema.

D. Cardiogenic shock: In cardiogenic shock, PAWP can be elevated due to impaired contractility, but it is accompanied by low cardiac output and hypotension. While related, the elevated PAWP in cardiogenic shock results from the underlying left ventricular failure, which is the primary cause of the pressure increase.

A. Assess the client's lung sounds prior to the infusion. B. Prime the infusion tubing with 0.45% sodium chloride. C. Don sterile gloves to prepare the blood administration setup. D. Verify with another nurse that the unit of blood is compatible with the client's blood type. E. Infuse the blood over 4 hr.

Correct Answer is ["A","D","E"]

Explanation

Rationale:
A. Assess the client's lung sounds prior to the infusion: Baseline lung assessment helps detect early signs of fluid overload or transfusion-associated circulatory overload (TACO), which is especially important in older adults.

B. Prime the infusion tubing with 0.45% sodium chloride: Only 0.9% sodium chloride (normal saline) is compatible with blood products. Hypotonic solutions such as 0.45% sodium chloride can cause hemolysis of red blood cells.

C. Don sterile gloves to prepare the blood administration setup: Clean gloves are sufficient for preparing and administering blood transfusions. Sterile gloves are not required unless performing a sterile procedure.

D. Verify with another nurse that the unit of blood is compatible with the client's blood type: Double verification of the client’s identity and blood compatibility prevents hemolytic transfusion reactions due to mismatched blood.

E. Infuse the blood over 4 hr: Each unit of packed RBCs should be transfused within no more than 4 hours to reduce the risk of bacterial contamination and hemolysis from prolonged infusion.
