ATI RN Custom Exams Set 1

1. For a patient on lithium therapy, which dietary recommendation is essential?

A. Increase caffeine intake
B. Increase sodium intake
C. Increase protein intake
D. Increase fiber intake

Correct answer: B

Rationale: The correct answer is to increase sodium intake. Maintaining consistent sodium levels is crucial for patients on lithium therapy to prevent fluctuations in drug levels. Increasing caffeine intake (Choice A) is not recommended as it can interfere with lithium levels. While protein intake (Choice C) is important, it is not the essential dietary recommendation for patients on lithium therapy. Similarly, increasing fiber intake (Choice D) is not a key recommendation for these patients.

2. The client diagnosed with diabetes mellitus type 2 is admitted to the hospital with cellulitis of the right foot secondary to an insect bite. Which intervention should the nurse implement first?

A. Administer intravenous antibiotics
B. Apply warm moist packs every two hours
C. Elevate the right foot on two pillows
D. Teach the client about skin and foot care

Correct answer: A

Rationale: Administering intravenous antibiotics is the priority intervention in this situation. Cellulitis is a bacterial infection that can spread rapidly, especially in individuals with diabetes. Immediate antibiotic therapy is crucial to prevent the infection from worsening and causing serious complications. Applying warm moist packs, elevating the foot, and teaching the client about skin and foot care are important interventions but should come after initiating antibiotic treatment to address the underlying infection.

3. During a physical assessment of a newborn, which of the following findings should the nurse prioritize reporting?

A. Head circumference of 40 cm
B. Chest circumference of 32 cm
C. Acrocyanosis and edema of the scalp
D. Heart rate of 160 bpm and respirations of 40/min

Correct answer: A

Rationale: The correct answer is A. A head circumference of 40 cm is abnormally large for a newborn and could indicate conditions like hydrocephalus or other abnormalities, making it a crucial finding to report. Choices B, C, and D are within normal parameters for a newborn and do not pose immediate concerns. Chest circumference of 32 cm is a normal finding. Acrocyanosis and edema of the scalp are common in newborns due to physiological adaptations. A heart rate of 160 bpm and respirations of 40/min may be within the normal range for a newborn.

4. A client who _ diet requires _ amounts of vitamin C.

A. Follows a vegan diet
B. Smokes cigarettes
C. Follows a ketogenic diet
D. Is lactose intolerant

Correct answer: B

Rationale: Clients who smoke require more vitamin C due to increased oxidative stress and depletion of vitamin C. Smoking leads to higher levels of oxidative stress in the body, which in turn increases the utilization of vitamin C to counteract the damage caused by free radicals. Choices A, C, and D do not directly impact the body's need for vitamin C as smoking does.

5. What is a primary intervention for managing hyperphosphatemia?

A. Increasing calcium intake
B. Increasing phosphorus intake
C. Decreasing calcium intake
D. Administering phosphate binders

Correct answer: D

Rationale: Administering phosphate binders is a primary intervention for managing hyperphosphatemia. Phosphate binders work by binding phosphorus in the gut, preventing its absorption. Increasing calcium intake (Choice A) is not a primary intervention for hyperphosphatemia and can actually exacerbate the condition by potentially raising calcium levels. Increasing phosphorus intake (Choice B) is contraindicated in hyperphosphatemia. Decreasing calcium intake (Choice C) may help manage hypercalcemia but is not the primary intervention for hyperphosphatemia.
