A newborn tests positive for the hepatitis B surface antigen. Which of the following should the nurse administer?

Hepatitis B vaccine monthly until the newborn tests negative for the hepatitis B surface antigen.

Hepatitis B immune globulin and hepatitis B vaccine within 12 hours of birth.

Hepatitis B immune globulin at 1 week followed by hepatitis B vaccine monthly for 6 months.

Hepatitis B vaccine at 24 hours followed by hepatitis B immune globulin every 12 hours for 3 days.

Answer and Explanation

The Correct Answer is B

Choice A rationale
While the hepatitis B vaccine is an important part of preventing hepatitis B infection, it is not typically given on a monthly basis until the newborn tests negative for the hepatitis B surface antigen. Instead, the vaccine is usually given in a series of three to four doses over a six-month period.
Choice B rationale
For newborns who test positive for the hepatitis B surface antigen, the current recommendation is to administer both the hepatitis B immune globulin (HBIG) and the

hepatitis B vaccine within 12 hours of birth. The HBIG provides immediate, short-term protection against the virus, while the vaccine stimulates the newborn’s immune system to provide long-term protection.
Choice C rationale
While the hepatitis B immune globulin (HBIG) and the hepatitis B vaccine are both important for preventing hepatitis B infection in newborns, they are not typically administered in the manner described in this choice. The HBIG is usually given once, within 12 hours of birth, while the vaccine is given in a series of three to four doses over a six-month period.
Choice D rationale
The hepatitis B vaccine is typically given within 24 hours of birth, but it is not followed by doses of the hepatitis B immune globulin (HBIG) every 12 hours for three days. Instead, a single dose of HBIG is usually given within 12 hours of birth, along with the first dose of the vaccine.

Correct Answer is C

Explanation

Choice A rationale
A probable sign of pregnancy includes objective signs observed by an examiner, such as changes in the pelvic organs, enlargement of the abdomen, and positive pregnancy test.
Choice B rationale
Possible signs of pregnancy are those that are subjective and reported by the patient, such as nausea, vomiting, and missed period. These signs could be due to other conditions.
Choice C rationale
Feeling the baby moving, also known as quickening, is a presumptive sign of pregnancy. These are changes felt by the woman herself and can be caused by other conditions.
Choice D rationale
Positive signs of pregnancy are those that are confirmed by the examiner and cannot be caused by any other condition. These include hearing the fetal heartbeat, visualizing the fetus, and feeling the baby move.

A. There is an increased risk of introducing infection. B. This could initiate preterm labor. C. This could result in profound bleeding. D. There is an increased risk of rupture of the membranes.

Correct Answer is C

Explanation

Choice A rationale
While it’s true that any internal examination carries a risk of introducing infection, this is not the primary reason to avoid an internal examination in a client with placenta previa.
Choice B rationale
Initiating preterm labor is a concern with any internal examination, but it’s not the primary reason to avoid an internal examination in a client with placenta previa.
Choice C rationale
This is the correct answer. In a client with placenta previa, an internal examination could disturb the placenta and cause severe, potentially life-threatening bleeding.
Choice D rationale
While rupture of the membranes is a risk associated with internal examinations, it’s not the primary reason to avoid an internal examination in a client with placenta previa.
