A nurse is preparing to apply lidocaine and prilocaine cream to a child prior to the insertion of an IV catheter. Which of the following actions should the nurse plan to take?
Avoid removing the cream prior to the procedure.
Rub the cream into the skin.
Apply the cream 1 hour before the procedure.
Wash the site with alcohol prior to applying the cream.
The Correct Answer is C
Choice A reason: Avoiding the removal of the cream prior to the procedure is important, but it does not specify when or how the cream should be applied, which is crucial for its effectiveness.
Choice B reason: Rubbing the cream into the skin is not recommended as it should be applied as a thick layer and covered with an occlusive dressing to ensure proper absorption and numbing effect.
Choice C reason: Applying the cream 1 hour before the procedure allows enough time for the lidocaine and prilocaine to take effect, providing adequate local anesthesia for the insertion of the IV catheter.
Choice D reason: Washing the site with alcohol prior to applying the cream is necessary to clean the area, but it is not the action that addresses the primary goal of numbing the site for the procedure.

Correct Answer is A
Explanation
Choice A reason: Keeping electrical wires hidden from view is essential to prevent toddlers from pulling on them, which can lead to electrical burns or other injuries. It is a proactive measure to ensure a safe environment for children who are naturally curious and prone to exploring with their hands.
Choice B reason: Turning pot handles toward the front of the stove is dangerous as it increases the risk of toddlers reaching up and pulling hot contents onto themselves. The correct practice is to turn pot handles toward the back of the stove to keep them out of reach of children.
Choice C reason: Encouraging outdoor activities between the hours of 11:00 and 13:00 can expose toddlers to the sun's peak intensity, increasing the risk of sunburn. It is safer to encourage outdoor activities outside these hours when the sun is less intense.
Choice D reason: Setting the water heater to 60°C (140°F) is too high and poses a scalding risk. The recommended temperature to prevent burns is 49°C (120°F), which is hot enough for household use but not so hot as to cause immediate burns upon contact.
Correct Answer is A
Explanation
Choice A reason: Treating everyone who came into close contact with the child is essential because scabies is highly contagious. The mites that cause scabies can easily spread to others through direct skin contact or by sharing personal items.
Choice B reason: Soaking combs and brushes in boiling water for 10 minutes is a good practice to kill any mites that may be present. However, it is not the primary method of treating scabies, which requires medication.
Choice C reason: Washing the child's hair with shampoo containing ketoconazole is not a standard treatment for scabies. Ketoconazole is an antifungal medication, and scabies is caused by mites, not fungi.
Choice D reason: Applying petroleum jelly to the affected areas is not an effective treatment for scabies. Scabies requires prescription medications, such as topical permethrin or oral ivermectin, to eliminate the mites.
