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: Using a bulb syringe to suction the nares is appropriate for an infant with bronchiolitis to help clear mucus and maintain airway patency, as bronchiolitis often causes nasal congestion.
Choice B reason: Initiating IV antibiotic therapy is not typically indicated for bronchiolitis, which is usually caused by a virus, and antibiotics are ineffective against viral infections.
Choice C reason: Administering a meningococcal vaccine upon admission is not related to the immediate care needs of an infant with bronchiolitis and is not part of standard treatment for this condition.
Choice D reason: Placing the infant in a room with negative-pressure airflow is not necessary for bronchiolitis, as this measure is reserved for airborne infections like tuberculosis, not for bronchiolitis which is spread through droplets.
Correct Answer is A
Explanation
Choice A reason: A creatinine level of 1.4 mg/dL is higher than the normal range for a 4-year-old child and could indicate kidney impairment, which is a concern when administering gentamicin due to its potential nephrotoxic effects. The provider should be informed immediately to assess kidney function and adjust the medication if necessary.
Choice B reason: A BUN level of 5 mg/dL is within the normal range for children and does not typically warrant immediate concern. However, it should be monitored along with creatinine levels to assess kidney function.
Choice C reason: A creatinine level of 0.3 mg/dL is within the normal range for a 4-year-old child and does not indicate an immediate concern. It should be monitored for any changes, especially when on gentamicin.
Choice D reason: A WBC count of 15,000/mm³ is slightly elevated, which may be expected in a child with meningitis as it indicates an immune response to infection. However, it is not as critical as an abnormal creatinine level in the context of gentamicin therapy.
