A newborn weighs 3400 grams.
The healthcare provider has ordered 0.2 mg/kg of atropine sulfate subcutaneously.
Based on the label below, how much will the nurse administer in mL? (Write in your answer).
The Correct Answer is ["1.7"]
Step 1: 2 mg/kg × 3400 g × (1 kg ÷ 1000 g) = 0.68 mg
Step 2: 68 mg × (1 mL ÷ 0.4 mg) = 1.7 mL.
The nurse will administer 1.7 mL.

Correct Answer is A
Explanation
Choice A rationale
Obtaining the client's personal and family medical history is essential during the initial prenatal visit. This history helps identify any genetic disorders or chronic conditions that might affect the pregnancy. It also provides insight into the client's overall health and any potential risk factors.
Choice B rationale
Information about prior pregnancies is important but not the first priority. Prior pregnancy information can provide insights into previous complications, but a comprehensive medical history should come first.
Choice C rationale
Checking the client's urine with a reagent strip is not the primary action during an initial visit. Urine tests are useful for detecting infections and certain conditions, but they come after a thorough history has been obtained.
Choice D rationale
Scheduling the client for prenatal laboratory testing is necessary, but it follows the initial assessment and history-taking. Laboratory tests help confirm the pregnancy and assess overall health but are not the first step.
Choice E rationale
Discussing chorionic villus sampling (CVS) is premature at this stage. CVS is a prenatal test conducted around 10-13 weeks for detecting chromosomal abnormalities, but it's not relevant during the initial visit without understanding the client's medical history.
Correct Answer is B
Explanation
Choice A rationale
Hepatitis B immune globulin at 1 week followed by hepatitis B vaccine monthly for 6 months is incorrect. This schedule delays the immune response and leaves the infant unprotected during the critical early period when the risk of transmission is highest.
Choice B rationale
Hepatitis B immune globulin and hepatitis B vaccine within 12 hr of birth is the correct approach. This combination provides immediate passive immunity through the immune globulin and active immunity through the vaccine, significantly reducing the risk of hepatitis B transmission from mother to child.
Choice C rationale
Hepatitis B vaccine monthly until the newborn tests negative for the hepatitis B surface antigen is incorrect. Monthly administration alone is insufficient without the initial dose of immune globulin, especially since the infant may remain at risk until the negative test result.
Choice D rationale
Hepatitis B vaccine at 24 hr followed by hepatitis B immune globulin every 12 hr for 3 days is incorrect. The delay in the first vaccine dose reduces its efficacy, and the immune globulin schedule does not align with established guidelines for preventing hepatitis B transmission.
