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.

Answer and Explanation

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 C

Explanation

Allowing time during the workday when each nurse can demonstrate proficiency is the best way to evaluate staff competency with the new equipment. This method ensures that the nurses can perform the skills correctly and safely under the charge nurse’s supervision and feedback.

Choice A is wrong because verbally questioning the staff about the new equipment does not assess their practical skills or ability to use the equipment correctly.

Choice B is wrong because requiring each nurse to take a written examination about the new equipment does not assess their hands-on skills or ability to troubleshoot problems with the equipment.

Choice D is wrong because asking each nurse to read the procedure and sign a form acknowledging competency does not verify that the nurses have understood the procedure or can apply it in practice.

It also relies on the nurses’ honesty and self-assessment, which may not be accurate or reliable.

A. Place the client on a cardiac monitor. B. Administer a laxative as ordered. C. Place the client on seizure precautions. D. Restrict high potassium foods.

Correct Answer is A

Explanation

This is because hypokalemia (low potassium level in the blood) can cause abnormal heart rhythms (arrhythmia) that can be life-threatening and require urgent medical attention. A cardiac monitor can help detect and treat any arrhythmia that may occur.

Choice B is wrong because administering a laxative can worsen hypokalemia by causing more potassium loss through the digestive tract. Laxative use is one of the possible causes of hypokalemia.

Choice C is wrong because placing the client on seizure precautions is not a priority intervention for hypokalemia. Seizures are not a common symptom of hypokalemia, although muscle weakness and cramps may occur.

Choice D is wrong because restricting high potassium foods is not a priority intervention for hypokalemia. In fact, increasing potassium intake through foods or supplements may be helpful in less serious cases of hypokalemia. However, this should be done according to the doctor’s recommendation and with careful monitoring of blood potassium levels.

Normal blood potassium levels for an adult range from 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L) can be life threatening.
