Question 1 of 5

The client is admitted with a suspected bowel obstruction. Which diagnostic test is most likely to confirm the diagnosis?

Correct Answer: A

Rationale: An abdominal X-ray is the initial test to confirm bowel obstruction, showing air-fluid levels or dilated loops of bowel. Barium enema and colonoscopy are contraindicated due to perforation risk, and ultrasound is less specific.

Question 2 of 5

Correct Answer: C

Rationale: Placenta previa causes painless vaginal bleeding due to the low-lying placenta separating from the uterine wall.

Question 3 of 5

The client with a cervical dilation of 8cm suddenly becomes short of breath,cyanotic and hypotensive. The nurse should suspect which of the following complications?

Correct Answer: A

Rationale: Amniotic fluid embolus is a rare but life-threatening complication characterized by sudden dyspnea cyanosis and hypotension due to amniotic fluid entering the maternal circulation. These symptoms are not typical of transition phase abruption or cord prolapse.

Question 4 of 5
