Answer to Question 1

C

Feedback
A This weight gain would be unhealthy for most women. This woman has a normal BMI and should gain 11.5 to 16 kg during pregnancy.
B This is the high end of the range of weight this woman should gain in her preg-nancy.
C This woman has a normal BMI and should gain 11.5 to 16 kg during pregnancy.
D This weight gain would be appropriate for an obese woman. This woman has a normal BMI, which indicates that her weight is average.

Answer to Question 2

1
Rationale:
1. Urine for a specific gravity test should be collected by placing cotton balls in the diaper. Only a small amount of clean (uncontaminated from stool) urine is needed to do a specific gravity test.
2. An in-and-out catheter would be invasive for this clean collection of a small amount of urine.
3. A urine bag can be irritating to the skin and would not be appropriate for collecting a small amount of urine for a specific gravity test.
4. A Foley catheter would be invasive for this clean collection of a small amount of urine.
