After teaching an in-service program to a group of nurses working in newborn nursery about a neutral thermal environment, the nurse determines that the teaching was successful when the group identifies which process as the newborn's primary method of heat production?

nonshivering thermogenesis

cold stress

convection

bilirubin conjugation

Answer and Explanation

The Correct Answer is A

A. Nonshivering thermogenesis is the primary method of heat production in newborns. Unlike adults, newborns do not generate heat through shivering. Instead, they rely on the metabolism of brown adipose tissue (brown fat) to produce heat. This process is triggered by exposure to cold and helps maintain body temperature.

B. Cold stress is a condition, not a heat production mechanism. It occurs when the newborn is exposed to cold temperatures, leading to increased oxygen and energy demands as the body attempts to produce heat — which can be dangerous.

C. Convection is a method of heat loss, not production. It occurs when heat is lost from the body surface to cooler surrounding air (e.g., drafts in the room).

D. Bilirubin conjugation is related to the liver's processing of bilirubin and has nothing to do with thermoregulation.

Correct Answer is A

Explanation

A. Elevated liver enzymes is a key indicator of HELLP syndrome, which stands for Hemolysis, Elevated Liver enzymes, and Low Platelets. HELLP syndrome is a severe form of preeclampsia and can lead to liver damage. Elevated liver enzymes, such as AST and ALT, are a hallmark of this condition, indicating liver dysfunction.

B. Elevated platelet count would be the opposite of what is expected in HELLP syndrome. In HELLP syndrome, there is typically low platelet count (thrombocytopenia), not an elevated one.

C. Leukocytosis refers to an increased white blood cell count, which can be indicative of an infection or inflammation, but it is not a hallmark of HELLP syndrome. HELLP syndrome primarily involves hemolysis, liver enzyme elevation, and low platelets.

D. Hyperglycemia is not a characteristic finding of HELLP syndrome. While it can occur in some pregnancy-related conditions, it is not specifically associated with HELLP syndrome. This condition is more associated with elevated liver enzymes and low platelets.

A. 50mg/hr B. 50ml/hr C. 5mg/mi D. 5ml/hr

Correct Answer is B

Explanation

A. 50mg/hr is not the correct unit for volume, it’s the dose in milligrams.
B. 50 mL/hr is the correct volume to administer to achieve the ordered dose of 2g/hr. Determine the concentration of the solution: The supply is 10g in 250mL. This means the concentration is 10g / 250mL, or 0.04g/mL (since 10g = 10,000mg, this is equivalent to 40mg/mL). Convert the ordered dose to match the concentration: The order is for 2g/hr (which is 2,000mg/hr). Calculate the volume to be infused to deliver the desired dose: Dose = Ordered/concentration= 2000/40= 50 mL/hr
C. 5mg/mL refers to the concentration, not the rate of infusion.
D. 5 mL/hr would administer only 200mg/hr, which is much lower than the ordered dose of 2g/hr.
