A 27-year-old pregnant woman was the restrained driver of a vehicle that hit the guardrail at a high rate of speed. She sustained a large laceration to the upper thigh and has lost a significant amount of blood. Vital signs are: heart rate 102, blood pressure 118/78 mmHg, respirations 18, and her skin is pale and clammy. Which of the following BEST explains this patient’s presentation?
Question 6 options:
A)
Maternal vital signs remain normal following trauma to ensure the survival of the developing fetus.
B)
Fetal oxygen demand increases after trauma, causing maternal blood pressure and heart rate to increase immediately after injury.
C)
Maternal blood volume decreases during pregnancy, amplifying the effects of epinephrine and allowing for the maintenance of blood pressure.
D)
Maternal blood volume increases during pregnancy, allowing vital signs to remain normal despite significant blood loss.

You are caring for a 42-year-old woman who is 32 weeks pregnant with twins. She is complaining of a severe headache and blurred vision, and lives in a rural area approximately 30 miles from the nearest ED. Your physical exam reveals significant peripheral edema and the following vital signs: heart rate 98, blood pressure 156/98 mmHg, respirations 18. The patient states she has a history of hypertension, but has not taken her prescribed medications because “they aren’t safe for the babies.” Appropriate treatment for this patient includes:

C)
insert a nasal airway, administer midazolam, and obtain vital signs.
D)
apply a nasal cannula, assess blood glucose level, and transport in the left lateral position.
