ATI RN Custom Exams Set 2

1. A client who _ diet requires _ amounts of vitamin C.

A. Follows a vegan diet
B. Smokes cigarettes
C. Follows a ketogenic diet
D. Is lactose intolerant

Correct answer: B

Rationale: Clients who smoke require more vitamin C due to increased oxidative stress and depletion of vitamin C. Smoking leads to higher levels of oxidative stress in the body, which in turn increases the utilization of vitamin C to counteract the damage caused by free radicals. Choices A, C, and D do not directly impact the body's need for vitamin C as smoking does.

2. 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.

3. Which lipoprotein carries cholesterol from tissues to the liver for excretion?

A. Very low-density lipoprotein
B. Intermediate-density lipoprotein
C. Low-density lipoprotein
D. High-density lipoprotein

Correct answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps transport excess cholesterol from tissues back to the liver for removal from the body. Very low-density lipoprotein (VLDL) (choice A) and intermediate-density lipoprotein (choice B) are involved in transporting triglycerides. Low-density lipoprotein (LDL) (choice C) is known as 'bad' cholesterol as it can deposit cholesterol in the walls of arteries.

4. Which of the following is a specialized medical treatment and teaching facility that provides general and specialized medical and dental care and treatment?

A. CONUS
B. MEDCEN
C. MEDCOM
D. MEDDAC

Correct answer: B

Rationale: The correct answer is B, MEDCEN, which stands for Medical Center. A MEDCEN is a specialized medical treatment and teaching facility that provides general and specialized medical and dental care and treatment. Choices A, C, and D are incorrect. CONUS refers to the continental United States and is not a medical facility. MEDCOM stands for Medical Command, which is an organization rather than a specific facility for medical treatment. MEDDAC stands for Medical Department Activity and is also an organization responsible for medical care delivery, not a specific treatment facility.

5. A client with type 1 diabetes is diagnosed with diabetic ketoacidosis and initially treated with intravenous fluids followed by an IV bolus of regular insulin. The nurse anticipates that the practitioner will prescribe a continuous infusion of insulin of:

A. Novolin L insulin
B. Novolin R insulin
C. Novolin N insulin
D. Novolin U insulin

Correct answer: B

Rationale: The correct answer is Novolin R (Regular insulin) because it is used for continuous infusion to treat diabetic ketoacidosis. Novolin R has a rapid onset of action, making it suitable for this acute situation. Novolin L insulin (Choice A) is not typically used for continuous infusion in diabetic ketoacidosis. Novolin N insulin (Choice C) is an intermediate-acting insulin and is not ideal for rapid correction needed in diabetic ketoacidosis. Novolin U insulin (Choice D) is an ultra-long-acting insulin and is not appropriate for the immediate correction required in this scenario.
