ATI RN

ATI RN Custom Exams Set 5

1. The nurse is aware that norepinephrine is secreted by which endocrine gland?

A. The pancreas
B. The adrenal cortex
C. The adrenal medulla
D. The anterior pituitary gland

Correct answer: C

Rationale: The correct answer is C: The adrenal medulla. Norepinephrine is secreted by the adrenal medulla and is involved in the body's 'fight or flight' response. The pancreas (choice A) secretes insulin and glucagon, not norepinephrine. The adrenal cortex (choice B) secretes hormones like cortisol and aldosterone, but not norepinephrine. The anterior pituitary gland (choice D) secretes various hormones like growth hormone and thyroid-stimulating hormone, but not norepinephrine.

2. Which of the following is a nonmedical member of a unit who receives additional training in providing care beyond basic first aid procedures?

A. Area support squad leader
B. ATLS specialist
C. Tactical lifesaver
D. Combat lifesaver

Correct answer: D

Rationale: The correct answer is D, Combat lifesaver. A Combat Lifesaver is a nonmedical member of a unit who receives specialized training in advanced first aid procedures, beyond basic first aid care. This training equips them to provide crucial medical assistance in emergency situations where immediate medical personnel may not be available. Choices A, B, and C are incorrect as they do not specifically refer to nonmedical members trained in advanced first aid care beyond basic procedures.

3. What type of diet is recommended for patients with diverticulitis during an acute flare-up?

A. High-fiber
B. Low-residue
C. Low-fat
D. High-protein

Correct answer: B

Rationale: During an acute flare-up of diverticulitis, a low-residue diet is recommended. This diet helps reduce bowel movements and minimize irritation to the digestive tract, allowing the inflamed diverticula to heal. High-fiber foods are usually avoided during flare-ups as they can exacerbate symptoms. Low-fat and high-protein diets are not specifically recommended for diverticulitis flare-ups. Therefore, option B is the correct choice.

4. 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.

5. 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. For patients on lithium therapy, maintaining consistent sodium intake is crucial to avoid 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 for overall health, it is not specifically essential for patients on lithium therapy. Similarly, increasing fiber intake (choice D) is beneficial but not a primary concern for patients on lithium therapy.
