When teaching a pregnant client who is complaining of aching swollen, leg veins, the
nurse would be explaining that this is most likely the result of which of the following?
A. thrombophlebitis
B. pregnancy induced hypertension
C. pressure on blood vessels from the enlarging uterus
D. the force of gravity pulling down on the uterus - Answer D - Explanation
The pressure from the expanding uterus on blood vessels makes the pregnant woman
more susceptible to venous stasis of the lower extremities. This could lead to edema
and the formation of varicose veins. Thrombophlebitis refers to inflammation of the
veins due to thrombus formation. Pregnancy-related hypertension does not contribute
to these symptoms. Gravity is only a minor contributing factor with these symptoms.
Which of the following would be a cause of a false-positive result on a pregnancy test?
A. Less than 10 days has elapsed since an abortion
B. Testing was done too early or too late in the
pregnancy
C. The urine specimen had been kept too long at room
temperature
D. A spontaneous abortion or a missed abortion is
pending - Answer A - Explanation
A false-positive reaction may be obtained if the
Pregnancy test is made less than 10 days following abortion. The testing of pregnancy
too early or too late in pregnancy, storage of urine sample for too long at room
temperature, and impending spontaneous or missed abortion are the causes for
false-negative results.
