ATI RN

ATI RN Custom Exams Set 3

1. 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.

2. A true statement about medications is that:

A. Over-the-counter medications are unlikely to interact with food or nutrients
B. Prescription medications always have significant interactions with food
C. Prescription and nonprescription drugs and herbal remedies interact with food
D. Herbal products are generally safe since they are natural

Correct answer: C

Rationale: The correct answer is C. This statement is true because both prescription and over-the-counter medications, as well as herbal remedies, can interact with food. Choice A is incorrect because over-the-counter medications can also interact with food or nutrients. Choice B is incorrect as not all prescription medications have significant interactions with food. Choice D is incorrect because natural herbal products can also have side effects and interactions with other substances.

3. 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.

4. The nurse understands that which are characteristics of anthrax? Select all that apply.

A. Cutaneous lesions become a black eschar, Flu-like symptoms are a sign of pulmonary anthrax
B. Cutaneous lesions become a black eschar
C. Gastrointestinal anthrax causes blood anthrax
D. Flu-like symptoms are a sign of pulmonary anthrax

Correct answer: A

Rationale: The correct characteristics of anthrax are that cutaneous lesions become a black eschar, and flu-like symptoms are typical of pulmonary anthrax. Choice B is incorrect as it only covers the cutaneous anthrax characteristic and does not include the flu-like symptoms of pulmonary anthrax. Choice C is incorrect as gastrointestinal anthrax does not cause 'blood anthrax,' and Choice D is incorrect as flu-like symptoms are not associated with gastrointestinal anthrax.

5. Who typically collects blood specimens?

A. The nurse
B. Medical technologist
C. Physician
D. Pharmacist

Correct answer: A

Rationale: Nurses typically collect blood specimens from patients as part of their everyday duties in medical settings. They are trained in venipuncture techniques and are responsible for ensuring that blood samples are properly obtained and labeled for diagnostic testing. Medical technologists process and analyze the blood specimens in the laboratory under the direction of a physician, but the actual collection of specimens is commonly performed by nurses. Physicians are primarily responsible for diagnosing and treating medical conditions rather than collecting blood specimens. Pharmacists are healthcare professionals who specialize in medication management and dispensing, not in collecting blood specimens.
