Correct Answer is C

Explanation

Rationale:

A) Incorrect - The umbilical area is not a typical location for auscultating fetal heart tones.
B) Incorrect - The suprapubic area is not a common location for auscultating fetal heart tones.
C) Correct - At 12 weeks of gestation, the nurse would typically auscultate the fetal heart tones above the left iliac crest, which is in the lower abdomen. This is where the uterus is located at this stage of pregnancy.
D) Incorrect - Auscultating below the liver border on the right abdomen is not a standard practice for fetal heart tone assessment.

A. Use a 20-gauge needle to administer the vaccine. B. Choose a 3/8-inch needle to administer the vaccine. C. Administer the vaccine into the dorsal gluteal muscle. D. Administer 0.5 mL of the vaccine.

Correct Answer is B

Explanation

A) Incorrect- A 20-gauge needle is too large and could cause unnecessary pain for the newborn.
B) Correct - Choosing a 3/8-inch needle is appropriate for administering vaccines to newborns. he hepatitis B vaccine is given intramuscularly in the anterolateral thigh of newborns. The needle size should be appropriate for the muscle mass and age of the infant. A 3/8-inch needle is recommended for newborns, while a 20-gauge needle is too large and may cause tissue damage.
C) Incorrect- Administering the vaccine into the dorsal gluteal muscle is not recommended because of the risk of injury to the sciatic nerve; the recommended site is the vastus lateralis muscle in the anterolateral thigh.
D) Incorrect- The hepatitis B vaccine is usually administered in a dose of 0.5 mL for newborns, but this is not the only action that the nurse should take.
