A nurse is assessing a newborn’s vital signs at 1 hour of age.
Which of the following findings should the nurse report to the provider?
Heart rate of 140/min
Respiratory rate of 50/min
Temperature of 36°C (96.8°F)
Blood pressure of 60/40 mm Hg
The Correct Answer is C
The correct answer is choice C. A temperature of 36°C (96.8°F) is below the normal range for a newborn, which is 36.5°C to 37.5°C (97.7°F to 99.5°F).
A low temperature can indicate hypothermia, infection, or hypoglycemia, and should be reported to the provider.
Choice A is wrong because a heart rate of 140/min is within the normal range for a newborn, which is 120 to 160/min.
Choice B is wrong because a respiratory rate of 50/min is within the normal range for a newborn, which is 30 to 60/min.
Choice D is wrong because a blood pressure of 60/40 mm Hg is within the normal range for a newborn, which is 50 to 75/30 to 45 mm Hg.

Correct Answer is B
Explanation
The correct answer is choice B. Give the vaccine intramuscularly in the anterolateral thigh.
This is because the anterolateral thigh is the recommended site for intramuscular injections in infants less than 12 months of age.
It has a large muscle mass and minimal risk of injury to nerves or blood vessels.
Choice A is wrong because informed consent is not required for routine immunizations, unless the parent or guardian requests more information or declines the vaccine.
Choice C is wrong because hepatitis B immune globulin (HBIG) is only indicated for newborns whose mothers are hepatitis B surface antigen positive (HBsAg+), as they have a high risk of acquiring the infection from their mothers.
Choice D is wrong because there is no need to delay giving the vaccine until after breastfeeding is established.
Breastfeeding does not interfere with the vaccine’s effectiveness or safety, and it does not increase the risk of adverse reactions.
