questions and answers
A 30-week pregnant trauma patient's vital signs include a blood
pressure of 94/62 mm Hg and a heart rate of 108 beats/minute.
Fetal heart tones are 124 beats/minute. The emergency nurse
interprets the patient's hemodynamic findings as an indication
of which of the following? - CORRECT ANSWER-normal vital
signs in pregnancy
rationale: in pregnancy, the resting heart rate increases by 10
to 20 bpm and a small decrease in systolic blood pressure and
a larger decrease in diastolic blood pressure due to a decrease
in peripheral resistance. Normal fetal rate is between 120 and
160 bpm
A patient fell two weeks ago, striking his head. He came to the
emergency department with a persistent headache and
nausea. He was diagnosed with a small subdural hematoma
and has been in the ED for 24 hours awaiting an inpatient bed.

swallowing and speaking. Further assessment is indicated next
for which of the following? - CORRECT ANSWER-damage to
