ATI RN Custom Exams Set 1

1. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

A. Platelets
B. Vitamin K
C. Calcium
D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

2. The system used at the division level and forward is comprised of six basic modules. Which module is staffed with two surgeons, two nurse anesthetists, a medical/surgical nurse, two operating room specialists, and two practical nurses?

A. Treatment squad
B. Area support squad
C. Medical service squad
D. Forward surgical team

Correct answer: D

Rationale: The correct answer is D, Forward Surgical Team (FST). The FST is indeed staffed with two surgeons, two nurse anesthetists, a medical/surgical nurse, two operating room specialists, and two practical nurses. This team is specifically trained and equipped to provide surgical intervention in austere environments where immediate medical care is needed. Choices A, B, and C do not match the personnel composition described in the question, making them incorrect. The Treatment squad typically focuses on patient care and recovery, the Area support squad provides logistical and administrative support, and the Medical service squad deals with broader medical services beyond surgical interventions.

3. Where do most peptic ulcers occur?

A. Esophagus
B. Stomach
C. Duodenum
D. Jejunum

Correct answer: C

Rationale: Most peptic ulcers occur in the duodenum, particularly in cases of duodenal ulcers. The correct answer is the duodenum because it is the most common site for peptic ulcers to develop. Peptic ulcers rarely occur in the esophagus and jejunum, making choices A, B, and D incorrect.

4. A client has been given instructions about ferrous sulfate. Which statement made by the client would indicate the client needs further education?

A. "I will take this medication with a full glass of milk."
B. "I will take the morning dose 1 hour before breakfast."
C. "I will need to avoid taking this medication with coffee."
D. "I will take antacids if needed, 2 hours after I take ferrous sulfate."

Correct answer: A

Rationale: The correct answer is A. Ferrous sulfate should not be taken with milk as it can impair iron absorption. Choice B is correct as taking the morning dose 1 hour before breakfast is appropriate. Choice C is correct as coffee can interfere with iron absorption. Choice D is correct as antacids should be taken 2 hours after ferrous sulfate to avoid interference with its absorption.

5. The client with chronic alcoholism has chronic pancreatitis and hypomagnesemia. What should the nurse assess when administering magnesium sulfate to the client?

A. Deep tendon reflexes
B. Arterial blood gases
C. Skin turgor
D. Capillary refill time

Correct answer: A

Rationale: Corrected Rationale: When administering magnesium sulfate to a client with chronic alcoholism, chronic pancreatitis, and hypomagnesemia, the nurse should assess deep tendon reflexes. Magnesium sulfate can depress the central nervous system and decrease deep tendon reflexes, so monitoring them is crucial. Assessing arterial blood gases, skin turgor, or capillary refill time is not directly related to the administration of magnesium sulfate in this scenario.
