ATI RN Custom Exams Set 3

1. Three major causes of atherosclerosis are:

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: Atherosclerosis is primarily caused by high blood cholesterol, high blood pressure, and cigarette smoking. These factors contribute to the buildup of plaque in the arteries. Choices A, C, and D are incorrect. Hyperthyroidism, underweight, and poor appetite do not directly cause atherosclerosis. Similarly, constipation, peptic ulcer disease, pancreatitis, kidney failure, edema, and sodium retention are not among the primary causes of atherosclerosis.

2. Under the health services support area concept, how is the medical care under the MEDCOM divided?

A. Six geographical regions of the United States with command authority in each region
B. Five levels of health service support, each providing different levels of health care services
C. Primary and secondary health care regions, each containing a MEDDAC or MEDCEN
D. Eight geographical areas of responsibility designated as health services support regions, each of which is subdivided into two or more health service areas

Correct answer: D

Rationale: The correct answer is D. Under the health services support area concept, the medical care under the MEDCOM is divided into eight geographical areas of responsibility designated as health services support regions, each of which is further subdivided into two or more health service areas. This structure allows for a more organized and efficient delivery of medical care across different regions. Choices A, B, and C are incorrect because they do not accurately describe how medical care under the MEDCOM is divided according to the concept of health services support areas.

3. In which situation(s) can personal health information be disclosed?

A. Compliance with legal proceedings
B. For research purposes in limited circumstances
C. To a family member or significant other in an emergency
D. All of the above

Correct answer: D

Rationale: Personal health information can be disclosed in various situations. Compliance with legal proceedings allows for disclosure under specific legal requirements. Disclosure for research purposes is permitted in limited circumstances with appropriate approvals. In emergencies, information can be shared with family members or significant others. Therefore, all of the choices are correct as they represent valid scenarios for disclosing personal health information.

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: To obtain accurate cultures of urethral and bladder urine, the nurse should instruct the patient to collect the first 15 mL of urine in one container and the subsequent 50 mL in another. This method ensures that the specimens are separated appropriately for analysis. Choices B, C, and D are incorrect because collecting three early morning urine specimens, massaging the prostate, or collecting a routine urine specimen would not provide the specific separation of urethral and bladder urine required for this particular test.

5. A patient with chronic renal failure should avoid which of the following?

A. Potassium
B. Calcium
C. Iron
D. Zinc

Correct answer: A

Rationale: Patients with chronic renal failure should avoid potassium due to impaired kidney function. The kidneys play a crucial role in regulating potassium levels in the body. In renal failure, the kidneys may not be able to excrete excess potassium effectively, leading to hyperkalemia. Calcium, iron, and zinc are not typically restricted in chronic renal failure unless there are specific individual circumstances, making them incorrect choices.
