1. 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.

2. Which of the following is something a new model for health care in the future should include?

• A. Community-centered care
• B. Care that encourages a healthy environment
• C. Accessible care that is affordable for most
• D. A focus on local health concerns

Correct answer: B

Rationale: The correct answer is B because a new model for health care in the future should focus on promoting a healthy environment. This includes initiatives such as green buildings and reducing pollution to improve overall health outcomes. Choice A, community-centered care, is important but not the primary focus when considering the future of healthcare. Choice C, accessible and affordable care, is crucial but does not directly address the need for a healthy environment. Choice D, a focus on local health concerns, is relevant but not as comprehensive as promoting a healthy environment in shaping the future of healthcare.

3. Rotating injection sites when administering insulin prevents which of the following complications?

• A. Insulin edema
• B. Insulin lipodystrophy
• C. Insulin resistance
• D. Systemic allergic reactions

Correct answer: B

Rationale: Rotating injection sites when administering insulin helps prevent insulin lipodystrophy, which is the abnormal distribution of fat at injection sites. Insulin edema (choice A) is not prevented by rotating injection sites; it is characterized by swelling at the site of insulin injection due to increased capillary permeability. Insulin resistance (choice C) is a condition where the body's cells become less responsive to insulin, and rotating injection sites does not directly prevent this. Systemic allergic reactions (choice D) are not specifically prevented by rotating injection sites; they are related to an allergic response to insulin.

4. Serge, who has diabetes mellitus, is taking oral agents and is scheduled for a diagnostic test that requires him to be NPO. What is the best plan of action for the nurse regarding Serge's oral medications?

• A. Administer the oral agents immediately after the test.
• B. Notify the diagnostic department and request orders.
• C. Notify the physician and request orders.
• D. Administer the oral agents with a sip of water before the test.

Correct answer: C

Rationale: The best plan of action for the nurse is to notify the physician and request orders regarding Serge's oral medications. By involving the physician, the nurse ensures that appropriate instructions are obtained, considering Serge's medical condition and the need for NPO status for the diagnostic test. Administering the medications without medical guidance (choice A) can be risky, as it may affect the test results. Notifying the diagnostic department (choice B) is not the most direct and appropriate action; the physician is the primary healthcare provider responsible for medication orders. Administering the medications with water before the test (choice D) is not advisable when the patient is supposed to be NPO, as it can interfere with the test requirements.

5. Select the stage of shock that is accurately paired with its characteristic.

• A. The initial stage of shock: Hyperventilation occurs and the blood pH rises.
• B. The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
• C. The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
• D. The refractory stage of shock: Potassium ions leak out; sodium ions build up, and metabolic acidosis increases.

Correct answer: C

Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.
