the correct EDD?
A. December 3rd
B. December 10th
C. December 17th
D. January 17th

last menstrual period and adding 7 days and 1 year. March 10 minus 3 months is December
10, plus 7 days is December 17.
2. Which assessment finding in a client with a long-bone fracture should lead
the nurse to suspect a fat embolism?
A. Petechiae over the chest and upper arms
B. Increased heart rate and numbness in the toes
C. Severe pain at the fracture site
D. Weakness in the affected extremity
Answer: A
Rationale: Petechiae on the chest and neck are a classic and distinguishing sign of fat
embolism syndrome, resulting from occlusion of small dermal capillaries.
,3. An LPN is caring for a client with Clostridium difficile (C. diff). Which infection

find:
A. Crackles in the lungs
B. Productive cough with pink frothy sputum
