Nursing Elites

1. You are teaching students about how hyperosmotic agents (osmotic diuretics) are used to treat intracranial pressure. Which of the following is NOT one of the functions of hyperosmotic agents?

• A. Reduces brain metabolism and systemic blood pressure
• B. Reduces cerebral edema
• C. Dehydrates the brain
• D. Draws fluids from extravascular spaces into the plasma

Correct answer: A

Rationale: Hyperosmotic agents primarily work by reducing cerebral edema, dehydrating the brain, and drawing fluids from extravascular spaces into the plasma. However, they do not have a direct effect on reducing brain metabolism or systemic blood pressure. Therefore, the correct answer is A. Choice B is correct as hyperosmotic agents do help in reducing cerebral edema. Choice C is accurate as hyperosmotic agents dehydrate the brain. Choice D is also true as these agents draw fluids from extravascular spaces into the plasma.

2. An adult female client with type 1 diabetes mellitus is receiving NPH insulin 35 units in the morning. Which finding should the PN document as evidence that the amount of insulin is inadequate?

• A. States that her feet are constantly cold and feel numb
• B. A wound on the ankle that starts to drain and becomes painful
• C. Consecutive evening serum glucose greater than 260 mg/dL
• D. Reports nausea in the morning but can still eat breakfast

Correct answer: C

Rationale: The correct answer is C. High evening glucose levels indicate that the morning dose of NPH insulin may be insufficient to control blood sugar throughout the day. Choice A is incorrect as cold and numb feet are more indicative of a circulation issue rather than an insulin inadequacy. Choice B suggests a wound infection rather than inadequate insulin. Choice D, nausea in the morning, may be due to other causes and does not necessarily indicate inadequate insulin dosage.

3. What is the primary function of hemoglobin in red blood cells?

• A. Oxygen transport
• B. Immunity
• C. Blood clotting
• D. Carbon dioxide transport

Correct answer: A

Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.

4. Which of the following best describes the role of insulin in the body?

• A. Insulin helps break down glucose into energy for the body
• B. Insulin facilitates the movement of glucose into cells
• C. Insulin converts excess glucose into fat for storage
• D. Insulin increases the breakdown of protein into amino acids

Correct answer: B

Rationale: The correct answer is B: Insulin facilitates the movement of glucose into cells. Insulin is a hormone that helps regulate blood sugar levels by promoting the uptake of glucose from the bloodstream into cells, where it can be used for energy production. Choice A is incorrect because insulin doesn't break down glucose but rather helps cells take up glucose. Choice C is incorrect as insulin does not directly convert glucose into fat; excess glucose is stored as fat by other processes. Choice D is incorrect as insulin does not increase the breakdown of protein into amino acids; its primary role is in glucose metabolism.

5. The nurse is performing a psychosocial assessment on an adolescent aged 14. Which emotional response is typical during early adolescence?

• A. Frequent anger
• B. Cooperativeness
• C. Moodiness
• D. Combativeness

Correct answer: C

Rationale: Moodiness is a typical emotional response during early adolescence. Hormonal changes and developmental challenges contribute to this behavior. While anger and combativeness can also be present during adolescence, they are not as consistently typical as moodiness. Cooperativeness, on the other hand, is a trait more commonly associated with later stages of development and maturity, rather than early adolescence.
