The nurse is preparing to provide a child with an injection. Which technique should the nurse use when applying EMLA cream to the injection site?

Wipe it off at least 15 minutes before the procedure

Do not cover it after application to prevent it from discoloring

Apply it immediately prior to the painful procedure

Apply it at least 1 hour before the procedure

Answer and Explanation

The Correct Answer is D

A. Wipe it off at least 15 minutes before the procedure: EMLA cream should be left on the skin for a sufficient amount of time to be effective, and it should not be wiped off too soon. It is typically left on for about 1 hour to ensure adequate numbing.

B. Do not cover it after application to prevent it from discoloring: EMLA cream should be covered with a dressing (such as plastic wrap) after application to help the cream stay in place and improve absorption. It should not be left uncovered.

C. Apply it immediately prior to the painful procedure: EMLA cream needs time to work, and applying it right before the procedure will not provide enough time for numbing. It should be applied at least 1 hour before the procedure for effective pain relief.

D. Apply it at least 1 hour before the procedure: EMLA cream should be applied at least 1 hour before the procedure to allow adequate time for the cream to penetrate the skin and provide effective local anesthesia.

Correct Answer is C

Explanation

A. Controls the risk of hypertension while pregnant: Folic acid does not have a direct role in controlling hypertension during pregnancy. Other factors, such as a balanced diet, exercise, and medication (if necessary), are typically involved in managing hypertension.

B. Sustains a slow and steady weight gain while pregnant: Folic acid does not directly influence weight gain during pregnancy. Its primary role is in fetal development, particularly in preventing neural tube defects, rather than managing weight.

C. Prevents neural tube defects in the developing fetus: Folic acid is essential in preventing neural tube defects (NTDs) such as spina bifida and anencephaly. It is recommended for all women of reproductive age, especially during the first trimester, to reduce the risk of these birth defects.

D. Maintains energy throughout the pregnancy: While folic acid is important for cell growth and development, it is not responsible for maintaining energy during pregnancy. Proper nutrition, rest, and overall health contribute to energy levels during pregnancy.

A. Slows and strengthens the heartbeat B. Prevents subacute bacterial endocarditis C. Thickens the walls of the myocardium D. Increases the heart rate

Correct Answer is A

Explanation

A. Slows and strengthens the heartbeat: Digoxin works by slowing the heart rate and increasing the force of the heart’s contractions. This helps improve cardiac output and is used to treat heart failure and certain types of arrhythmias in infants.

B. Prevents subacute bacterial endocarditis: Digoxin does not prevent subacute bacterial endocarditis. Antibiotics are typically used to prevent endocarditis, not digoxin. Digoxin's action is focused on regulating heart function rather than preventing infections.

C. Thickens the walls of the myocardium: Digoxin does not affect the thickness of the myocardial walls. Its primary action is to improve the heart's pumping efficiency by increasing the strength of contractions and controlling the heart rate.

D. Increases the heart rate: Digoxin slows the heart rate, which is useful for treating conditions like tachycardia. It does not increase the heart rate.
