Nursing Elites

1. Insulin forces which of the following electrolytes out of the plasma and into the cells?

• A. Calcium
• B. Magnesium
• C. Phosphorus
• D. Potassium

Correct answer: D

Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

2. A nurse on a med-surg unit is caring for a group of clients with the assistance of an LPN and an AP. Which of the following tasks should the nurse assign to the LPN?

• A. Reinforce dietary teaching with a client who has heart disease.
• B. Obtaining a urine specimen from an older adult client
• C. Providing postmortem care for a client who has just died.
• D. Accompanying a client who just had a wound debridement to PT.

Correct answer: A

Rationale: The correct answer is to reinforce dietary teaching with a client who has heart disease. This task falls within the LPN's scope of practice as they can provide education and support related to nutrition. Obtaining a urine specimen (Choice B) is typically performed by nursing assistants. Providing postmortem care (Choice C) is a sensitive task usually performed by registered nurses. Accompanying a client to physical therapy (Choice D) is often done by nursing assistants or other supportive staff.

3. Which individual is most at risk for Osgood-Schlatter disease?

• A. An elderly female who is hospitalized with a hip fracture and on bed rest
• B. A middle-aged male patient who has been exposed to asbestos in the shipping industry
• C. An adolescent who is physically active and the captain of their soccer team
• D. An infant of low birth weight and a gestational age of 28 weeks

Correct answer: C

Rationale: Osgood-Schlatter disease is a condition that commonly affects adolescents who are physically active, especially during growth spurts. It is caused by overuse of the knee, leading to inflammation of the patellar ligament at the tibial tuberosity. The repetitive stress on the growth plate during activities like running and jumping can trigger this condition. Therefore, an adolescent who is physically active and the captain of their soccer team is most at risk for Osgood-Schlatter disease. Choices A, B, and D are not at high risk for this condition as it is primarily seen in active adolescents.

4. A nurse is assessing a client with a suspected diagnosis of hypocalcemia. Which of the following clinical manifestations would the nurse expect to note in the client?

• A. Twitching
• B. Positive Trousseau's sign
• C. Hyperactive bowel sounds
• D. Hyperactive deep tendon reflexes

Correct answer: A

Rationale: The correct answer is A: Twitching. Hypocalcemia often presents with neuromuscular irritability, leading to manifestations such as twitching. Trousseau's sign is actually a positive indicator of hypocalcemia, not negative, making choice B incorrect. Hypoactive bowel sounds are not typically associated with hypocalcemia, making choice C incorrect. Similarly, hypoactive deep tendon reflexes are not a common finding in hypocalcemia, making choice D incorrect.

5. Which insulin has the most rapid onset of action?

• A. Lente
• B. Lispro
• C. Ultralente
• D. Humulin N

Correct answer: B

Rationale: Lispro insulin has the most rapid onset of action among the options provided. It is a rapid-acting insulin analog that is designed to control postprandial hyperglycemia effectively. Lente insulin (Choice A) and Ultralente insulin (Choice C) are intermediate-acting insulins, which have a slower onset of action compared to Lispro. Humulin N (Choice D) is a neutral protamine Hagedorn (NPH) insulin, which is an intermediate-acting insulin, not rapid-acting like Lispro. Therefore, the correct choice is Lispro.
