ATI RN Custom Exams Set 1

1. What causes hepatic encephalopathy?

A. Buildup of ammonia in the body
B. Buildup of urea in the body
C. Fatty infiltration of the liver
D. Jaundice

Correct answer: A

Rationale: Hepatic encephalopathy is caused by the buildup of ammonia in the body. Ammonia, a byproduct of protein metabolism, normally gets converted to urea in the liver for excretion. However, in liver dysfunction, such as cirrhosis, the liver cannot effectively convert ammonia to urea, leading to its accumulation in the body and subsequently causing hepatic encephalopathy. Choices B, C, and D are incorrect as they do not directly relate to the pathophysiology of hepatic encephalopathy.

2. Who is at higher risk for drug-nutrient interactions?

A. Infants
B. People with diabetes
C. Women of childbearing age
D. Older men and women

Correct answer: D

Rationale: Older men and women are at higher risk for drug-nutrient interactions due to factors such as polypharmacy and physiological changes. Polypharmacy, common in older adults, increases the likelihood of interactions between drugs and nutrients. Physiological changes that occur with aging can affect how drugs and nutrients are absorbed, distributed, metabolized, and excreted in the body. Infants, people with diabetes, and women of childbearing age are not typically considered high-risk groups for drug-nutrient interactions compared to older adults.

3. Which type of anemia is associated with chronic kidney disease?

A. Iron-deficiency anemia
B. Vitamin B12 deficiency anemia
C. Aplastic anemia
D. Erythropoietin deficiency anemia

Correct answer: D

Rationale: The correct answer is D: Erythropoietin deficiency anemia. Chronic kidney disease often leads to anemia due to decreased production of erythropoietin. This hormone, produced by the kidneys, stimulates red blood cell production in the bone marrow. Iron-deficiency anemia (choice A) is more commonly caused by insufficient dietary iron intake or chronic blood loss. Vitamin B12 deficiency anemia (choice B) is usually due to inadequate dietary intake, malabsorption, or pernicious anemia. Aplastic anemia (choice C) is a bone marrow failure disorder characterized by pancytopenia (decreased red blood cells, white blood cells, and platelets) rather than a deficiency in erythropoietin production.

4. The HCP orders cultures of the urethral urine, bladder urine, and prostatic fluid. Which instructions would the nurse teach to achieve the first two (2) specimens?

A. Collect the first 15 mL in one jar and then the next 50 mL in another
B. Collect three (3) early morning, clean voided urine specimens
C. Collect the specimens after the HCP massages the prostate
D. Collect a routine urine specimen for analysis

Correct answer: A

Rationale: The correct answer is to collect the first 15 mL in one jar and then the next 50 mL in another. This method allows for accurate cultures of urethral and bladder urine. Choice B is incorrect because it does not specify the correct method for collecting urethral and bladder urine separately. Choice C is incorrect because prostatic fluid is a separate specimen that does not require prostatic massage for collection. Choice D is incorrect as it suggests collecting a routine urine specimen, which does not fulfill the HCP's orders for specific cultures.

5. Listed below are five categories that identify the responsibilities of the practical nurse manager in personnel management. Which of these categories is most appropriate for the task of 'Ensuring that soldiers are utilized in their MOS'?

A. Accountability
B. Personal/professional development
C. Individual training
D. Military appearance/physical condition

Correct answer: A

Rationale: The correct answer is 'Accountability.' Accountability involves ensuring that individuals are utilized effectively in their assigned roles, which aligns with the task of 'Ensuring that soldiers are utilized in their MOS.' Personal/professional development (choice B) focuses on personal growth and skill enhancement rather than role utilization. Individual training (choice C) pertains to specific skill development rather than overall role utilization. Military appearance/physical condition (choice D) relates to physical fitness and appearance standards, not role assignments.
