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 A
Explanation
Nonmaleficence is the ethical principle of doing no harm or preventing harm to a client. It is based on the Hippocratic oath of “primum non nocere” or “first, do no harm”. It means that the nurse should act in the best interest of the client and avoid any actions that could cause injury or suffering.
Choice B. Fidelity is the ethical principle of being faithful and loyal to a client.
It means that the nurse should keep promises, respect confidentiality, and maintain trust.
Choice C. Justice is the ethical principle of treating clients fairly and equally.
It means that the nurse should distribute resources and services based on the client’s needs and not on personal biases.
Choice D. Autonomy is the ethical principle of respecting a client’s right to make their own decisions.
It means that the nurse should inform the client of their options and support their choices, as long as they do not harm others.
Correct Answer is A
Explanation
Choice B is wrong because laying down for 1 hour after meals can increase the pressure on the diaphragm and make breathing more difficult. It can also increase the risk of aspiration and reflux.
Choice C is wrong because restricting the client’s fluid intake to less than 1 L/day can lead to dehydration and thickening of secretions, which can obstruct the airways and impair gas exchange. Fluid intake should be adequate to maintain hydration and thin secretions.
Choice D is wrong because using the upper chest for respiration is a sign of inefficient breathing and respiratory distress.
It can increase the oxygen demand and cause fatigue. The client should be encouraged to use the diaphragm and abdominal muscles for respiration, which are more efficient and reduce the work of breathing.
Normal ranges for oxygen saturation are 95% to 100%, for arterial blood gas pH are 7.35 to 7.45, for PaCO2 are 35 to 45 mmHg, for PaO2 are 80 to 100 mmHg, and for HCO3 are 22 to 26 mEq/L.
