Explanation for Each Question | Galen
1. A nurse is calculating a client’s estimated date of birth using Naegele’s rule. The
client’s last menstrual period began on October 1st. Which of the following dates
should the nurse determine is the estimated date of delivery?
A. July 1st
B. January 7th
C. June 24th
D. July 8th
Correct Answer: D
Expert Explanation: Naegele’s rule is a standard method used to estimate the
delivery date by calculating from the first day of the last menstrual period. The
formula involves subtracting three months from the month of the LMP and adding
seven days to the day. In this specific case, October minus three months is July, and
adding seven days to the 1st results in July 8th.
,2. A nurse is assessing a newborn and notes a heart rate of 110 beats per minute, a
weak cry, some flexion of the extremities, grimacing when stimulated, and a body that
is pink with blue extremities. What is the Apgar score?
A. 5
B. 8
C. 7
D. 6
Correct Answer: D
Expert Explanation: The Apgar score is calculated by evaluating five categories:
heart rate, respiratory effort, muscle tone, reflex irritability, and color. For this
newborn, the heart rate (over 100) gets 2 points, weak cry gets 1 point, some flexion
gets 1 point, grimace gets 1 point, and acrocyanosis gets 1 point. Adding these
together results in a total Apgar score of 6.
3. A nurse is caring for a client who is in the first stage of labor and has a fetal heart
rate tracing showing late decelerations. Which of the following actions should the
nurse take first?
A. Increase the IV fluid rate
B. Notify the healthcare provider
,C. Administer oxygen via face mask
D. Assist the client into a side-lying position
Correct Answer: D
Expert Explanation: Late decelerations are indicative of uteroplacental
insufficiency, which can be life-threatening to the fetus. The first nursing
intervention should be to improve blood flow to the placenta by changing the
mother’s position to a lateral side-lying one. This action relieves pressure on the
inferior vena cava and improves cardiac output and placental perfusion.
4. A nurse is teaching a parent of a 2-year-old child about safe food choices. Which of
the following foods should the nurse recommend?
A. Whole grapes
B. Hot dog slices
C. Popcorn
D. Banana slices
Correct Answer: D
Expert Explanation: Toddlers are at high risk for choking due to their developing
chewing and swallowing skills. Foods like whole grapes, popcorn, and hot dog slices
are common choking hazards because of their size and consistency. Soft fruits like
, banana slices are safer because they are easily mashed and swallowed by a young
child.
5. A client at 32 weeks of gestation is admitted with a diagnosis of preeclampsia.
Which of the following findings should the nurse report to the provider immediately?
A. 1+ pedal edema
B. A blood pressure of 148/92 mmHg
C. Report of a persistent headache
D. 3+ protein in the urine
Correct Answer: C
Expert Explanation: While protein in the urine and elevated blood pressure are
common findings in preeclampsia, a persistent headache can be a sign of worsening
condition or impending eclampsia. This symptom suggests cerebral edema and
increases the risk for seizures. Prompt reporting is essential to initiate seizure
precautions and potential magnesium sulfate therapy.
6. A nurse is preparing to administer the Hepatitis B vaccine to a newborn. At which
site should the nurse plan to administer the injection?
A. Deltoid muscle
B. Dorsogluteal muscle
