The nurse knows that infants have a high risk of hypothermia due to decreased brown fat, immature skin, and poorly developed thermoregulatory mechanism.
Which nursing intervention is done to prevent heat loss by conduction?
Closing doors and windows to prevent draft (current of air with motion).
Keeping a hat on the baby’s head.
Thoroughly drying infant after a bath.
Placing a warm blanket on the scale prior to obtaining baby’s weight.
The Correct Answer is D
This is because heat loss by conduction occurs when two objects with different temperatures come into direct contact with each other. The baby’s skin would lose heat to the cold scale by conduction if there was no warm blanket between them.
Choice A is wrong because closing doors and windows to prevent draft (current of air with motion) would prevent heat loss by convection, not conduction. Convection is the transfer of heat from a body to moving molecules such as air or liquid.
Choice B is wrong because keeping a hat on the baby’s head would prevent heat loss by radiation, not conduction. Radiation is the transfer of heat from a body to the surroundings by electromagnetic waves.
Choice C is wrong because thoroughly drying infant after a bath would prevent heat loss by evaporation, not conduction. Evaporation is the process of liquid changing into gas and carrying away heat from the body surface.

Correct Answer is D
Explanation
Localized warmth at the site of injury is a sign of localized inflammation of the tissues, which is a response to tissue damage caused by an ankle injury. Localized inflammation involves changes in blood flow, vessel permeability, and leukocyte migration to the site of injury. Heat is one of the five classic signs of acute local inflammation, along with redness, swelling, pain, and loss of function.
Choice A is wrong because 3+ palpable pedal pulses below the affected injury site indicate normal blood flow to the foot and do not reflect inflammation.
Choice B is wrong because full range of motion at the site of injury is unlikely in the presence of inflammation, which usually causes pain and loss of function.
Choice C is wrong because sanguineous drainage at the site of injury is a sign of bleeding, not inflammation.
Inflammation may cause fluid leakage from blood vessels, but this fluid is usually clear or yellowish, not bloody.
Correct Answer is A
Explanation
One of the highest levels of evidence are randomized, controlled, double-blind studies. This is because these studies reduce the risk of bias and confounding factors by randomly assigning participants to intervention or control groups, blinding the participants and researchers to the group allocation, and using a placebo or standard treatment as a comparison.
Choice B is wrong because ideas, editorials, and opinions are considered low levels of evidence as they are based on personal views and not on rigorous research methods.
Choice C is wrong because the purpose of the hierarchy of evidence is to help the nurse evaluate the quality and strength of the research findings, not to compare patient values with research findings.
Patient values are important for evidence-based practice, but they are not part of the hierarchy of evidence.
Choice D is wrong because all forms of evidence should not be considered equally when determining evidence-based practice. The hierarchy of evidence ranks different types of research designs according to their validity and applicability, and the nurse should use the highest level of evidence available for their clinical question.
