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 works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.
2. The nurse prepares to administer digoxin (Lanoxin) to a newborn with a diagnosis of heart failure and notes that the apical rate is 140 beats per minute. Which nursing action is appropriate?
- A. Hold the medication
- B. Administer the digoxin
- C. Notify the healthcare provider
- D. Recheck the apical rate in 1 hour
Correct answer: B
Rationale: The correct answer is to administer the digoxin. An apical rate of 140 bpm is within the normal range for a newborn. Digoxin is commonly prescribed for heart failure in newborns to help improve cardiac function. Holding the medication or notifying the healthcare provider is not necessary as the heart rate is normal for a newborn. Rechecking the apical rate in 1 hour is not needed since the heart rate is within the expected range.
3. People who use monoamine oxidase inhibitors for the treatment of depression need to avoid foods high in:
- A. Folate
- B. Tyramine
- C. Potassium
- D. Vitamin K
Correct answer: B
Rationale: The correct answer is B: Tyramine. When individuals taking monoamine oxidase inhibitors (MAOIs) consume foods high in tyramine, it can lead to a potentially dangerous increase in blood pressure known as a hypertensive crisis. Foods high in tyramine include aged cheeses, cured meats, and certain fermented foods. Choices A, C, and D are incorrect. Folate, potassium, and vitamin K are not typically contraindicated with the use of MAOIs.
4. In managing cystic fibrosis, which nutrition therapy is crucial for patients with pancreatic insufficiency?
- A. A low-fat diet to prevent steatorrhea
- B. A low-sodium diet to normalize fluid status
- C. A high-fiber diet to normalize bowel function
- D. Pancreatic enzyme replacement therapy to help digestion
Correct answer: D
Rationale: In cystic fibrosis patients with pancreatic insufficiency, pancreatic enzyme replacement therapy is vital for aiding digestion. This therapy helps compensate for the decreased production of digestive enzymes by the pancreas, enabling the proper breakdown and absorption of nutrients. Options A, B, and C are not the primary focus of nutrition therapy for cystic fibrosis patients with pancreatic insufficiency.
5. What is the mission of the Army Medical Department?
- A. Ensure that each soldier receives a physical examination annually
- B. Deliver healthcare to regions of the U.S. designated as disaster areas by the President
- C. Maintain the health of the Army and preserve its combat effectiveness
- D. Offer medical, dental, and veterinary education and training
Correct answer: C
Rationale: The correct answer is C: 'Maintain the health of the Army and preserve its combat effectiveness.' This mission statement reflects the primary goal of the Army Medical Department, which is to ensure that military personnel remain healthy and fit for duty to preserve the Army's fighting strength. Choices A, B, and D are incorrect because they do not capture the core purpose of the Army Medical Department, which is focused on the health and readiness of the military forces, rather than performing annual physical examinations, responding to disasters, or providing education and training.
