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. 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 'listening and responding to soldiers' suggestions and complaints'?

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

Correct answer: A

Rationale: The correct answer is A. Accountability in personnel management involves being answerable for one's actions and decisions, which includes listening to and addressing the suggestions and complaints of soldiers. This category focuses on the responsibility and answerability aspect of the nurse manager's role. Choices B, C, and D are incorrect because personal/professional development is about growth and improvement, individual training pertains to specific skill development, and military appearance/physical condition relates to the physical presentation and fitness levels, none of which directly address the task of listening and responding to soldiers' suggestions and complaints.

3. The nurse is analyzing laboratory values for the assigned clients. Which finding, based on the client's medical history, indicates the need for immediate follow-up?

A. Client with chronic kidney disease and serum creatinine of 1.6 mg/dL
B. Client with diabetes mellitus and a glycosylated hemoglobin A (HbA1c) of 7.0%
C. Client with heart failure and a B-type natriuretic peptide (BNP) of 140 pg/mL
D. Client who is male and has anemia with hemoglobin of 16.5 g/dL and hematocrit of 45%

Correct answer: B

Rationale: An HbA1c of 7.0% in a client with diabetes mellitus indicates poor long-term glucose control, necessitating immediate follow-up. Elevated HbA1c levels suggest a higher average blood sugar over the past 2-3 months, increasing the risk of complications associated with diabetes. Choices A, C, and D do not require immediate follow-up based solely on the provided information. A serum creatinine of 1.6 mg/dL in a client with chronic kidney disease, a BNP of 140 pg/mL in a client with heart failure, and hemoglobin of 16.5 g/dL and hematocrit of 45% in a male client with anemia are within acceptable ranges or do not indicate an urgent need for intervention.

4. The hypertonicity of the muscles in an infant with cerebral palsy causes scissoring of the legs. The nurse teaches the mother that the preferred way to carry the infant is in a sitting position:

A. Astride one of her hips
B. Strapped in an infant seat
C. Wrapped tightly in a blanket
D. Under the arm using a football hold

Correct answer: A

Rationale: The correct way to carry an infant with cerebral palsy experiencing muscle hypertonicity and scissoring of the legs is astride one of the mother's hips. This position helps keep the infant's legs apart, reducing muscle tightness. Strapping the infant in an infant seat, wrapping tightly in a blanket, or using the football hold under the arm does not address the specific needs related to muscle hypertonicity and scissoring of the legs in cerebral palsy.

5. Neomycin may decrease absorption of which nutrient?

A. Iron, copper, and zinc
B. Protein and amino acids
C. Fat-soluble vitamins
D. Water-soluble vitamins

Correct answer: C

Rationale: The correct answer is C: Fat-soluble vitamins. Neomycin is known to interfere with the absorption of fat-soluble vitamins. This is because neomycin can disrupt the normal gut flora responsible for the absorption of these vitamins. Choices A, B, and D are incorrect because neomycin primarily affects the absorption of fat-soluble vitamins, not minerals, proteins, amino acids, or water-soluble vitamins.
