ATI RN Custom Exams Set 3

1. What are three major causes of atherosclerosis?

A. Hyperthyroidism, underweight, and poor appetite
B. High blood cholesterol, high blood pressure, and cigarette smoking
C. Constipation, peptic ulcer disease, and pancreatitis
D. Kidney failure, edema, and sodium retention

Correct answer: B

Rationale: The correct answer is B: High blood cholesterol, high blood pressure, and cigarette smoking are three major causes of atherosclerosis. Atherosclerosis is mainly attributed to the buildup of cholesterol-rich plaques in the arteries, high blood pressure causing damage to the arterial walls, and the harmful effects of cigarette smoking on blood vessels. Choices A, C, and D are incorrect because they do not directly relate to the primary causes of atherosclerosis.

2. When a patient is prescribed an oral anticoagulant, what should the nurse monitor for?

A. Elevated blood glucose
B. Decreased blood pressure
C. Signs of bleeding
D. Increased appetite

Correct answer: C

Rationale: When a patient is prescribed an oral anticoagulant, the nurse should monitor for signs of bleeding. Oral anticoagulants work by inhibiting the blood's ability to clot, which increases the risk of bleeding. Monitoring for signs of bleeding such as easy bruising, petechiae, hematuria, or bleeding gums is crucial to prevent complications. Elevated blood glucose (Choice A) is not directly related to oral anticoagulant use. Decreased blood pressure (Choice B) is not a common effect of oral anticoagulants. Increased appetite (Choice D) is not a typical side effect of oral anticoagulants and is not a primary concern when monitoring a patient on this medication.

3. The nurse is caring for a client who goes into ventricular tachycardia. Which intervention should the nurse implement first?

A. Call a code immediately
B. Assess the client for a pulse
C. Begin chest compressions
D. Continue to monitor the client

Correct answer: B

Rationale: The correct first intervention when a client goes into ventricular tachycardia is to assess for a pulse. This is crucial as the presence or absence of a pulse guides subsequent actions. Initiating chest compressions or calling a code should only be done after confirming the absence of a pulse. Continuing to monitor the client without checking for a pulse delays potentially life-saving interventions.

4. What is the combat health support system in the field designed to do?

A. Provide evacuation to the far rear for treatment and delay return to duty
B. Project, sustain, and protect the health of the soldier in war and operations other than war
C. Provide rearward evacuation and reassignment
D. Provide far rear area care and delayed return to duty

Correct answer: B

Rationale: The correct answer is B. The combat health support system in the field is designed to project, sustain, and protect the health of soldiers in both war and operations other than war. Choice A is incorrect because the system is not primarily focused on providing evacuation to the far rear for treatment, but rather on overall health support. Choice C is incorrect as it only mentions rearward evacuation and reassignment, which is a limited scope compared to the comprehensive support provided by the system. Choice D is incorrect as it narrowly focuses on far rear area care and delayed return to duty, missing the broader aspects of health support and protection.

5. 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 A1c (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. Choice A, chronic kidney disease with a serum creatinine of 1.6 mg/dL, though concerning, does not indicate an immediate need for follow-up. Choice C, heart failure with a BNP of 140 pg/mL, may require monitoring but not immediate follow-up. Choice D, a male client with anemia and normal hemoglobin and hematocrit levels, does not warrant immediate attention based on the provided information.
