Nursing Elites

1. The type of lipoprotein that carries cholesterol from tissues to the liver for excretion is:

• 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 the 'good' cholesterol and plays a crucial role in transporting cholesterol from tissues back to the liver for excretion. This process helps in reducing the buildup of cholesterol in the bloodstream, thus lowering the risk of heart diseases. Very low-density lipoprotein (Option A), Intermediate-density lipoprotein (Option B), and Low-density lipoprotein (Option C) are not responsible for carrying cholesterol back to the liver for excretion like HDL does. Instead, they are associated with different functions related to cholesterol transportation within the body.

2. The best position for any procedure that involves vaginal and cervical examination is

• A. Dorsal recumbent
• B. Side lying
• C. Supine
• D. Lithotomy

Correct answer: D

Rationale: The lithotomy position is the most suitable position for procedures involving vaginal and cervical examination because it provides the best access to the vaginal and cervical regions. In this position, the patient lies on their back with their legs flexed and feet placed in stirrups, allowing for optimal visualization and access to the area. This position facilitates proper examination, diagnosis, and treatment when working in the gynecological field. The other options (dorsal recumbent, side lying, and supine) do not provide the same level of access and visualization as the lithotomy position, making them less ideal for vaginal and cervical examinations.

3. 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). Regular insulin is used for continuous infusion to treat diabetic ketoacidosis due to its rapid onset of action. Novolin L (Intermediate-acting insulin) (choice A), Novolin N (Intermediate-acting insulin) (choice C), and Novolin U (Ultra-Long-acting insulin) (choice D) are not suitable for continuous infusion in the treatment of diabetic ketoacidosis.

4. A family came to the emergency department with complaints of food poisoning. Which client should the nurse see first?

• A. 32-year-old with diarrhea for 6 hours
• B. 2-year-old with 1 wet diaper in 24 hours
• C. 40-year-old with abdominal cramping
• D. 10-year-old who is nauseated

Correct answer: B

Rationale: In cases of food poisoning, a 2-year-old with reduced urine output is a critical finding indicating dehydration, requiring immediate attention to prevent complications. The reduced urine output is a sign of decreased fluid intake or increased fluid loss, putting the child at high risk for dehydration. This client should be seen first to assess hydration status, initiate necessary interventions, and prevent further complications. While the other symptoms presented by the other clients are concerning, the 2-year-old's decreased urine output poses the most immediate threat to their well-being.

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.
