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. 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.

3. You are working on a pediatric unit. Which toy or other diversional item or activity is most appropriate for your 18-month-old patient?

• A. Story books
• B. Beach balls
• C. An interactive play session with other children less than 2 years of age
• D. Pickup sticks

Correct answer: B

Rationale: A beach ball is appropriate for an 18-month-old as it is safe and can help with motor skills development. Choice A, storybooks, may not be suitable for this age group due to limited attention span. Choice C involves interaction with other children which may not always be feasible in a healthcare setting. Choice D, pickup sticks, poses a choking hazard and is not suitable for toddlers.

4. Multifetal pregnancies with triplets occur at a rate of 1 in 8,100 births, but twins occur much more frequently with a rate of:

• A. 1 in 85 births.
• B. 1 in 5400 births.
• C. 1 in 2700 births.
• D. 1 in 540 births

Correct answer: A

Rationale: The correct answer is A: 1 in 85 births. The rate of twin pregnancies is approximately 1 in 85 births. This means that twins are more common compared to triplets, which occur at a rate of 1 in 8,100 births. Choices B, C, and D are incorrect because they do not reflect the correct frequency of twin pregnancies as stated in the question.

5. A clinical instructor teaches a class for the public about diabetes mellitus. Which individual does the nurse assess as being at highest risk for developing diabetes?

• A. The 50-year-old client who does not engage in any physical exercise
• B. The 56-year-old client who drinks three glasses of wine daily
• C. The 42-year-old client who is 50 pounds overweight
• D. The 38-year-old client who smokes one pack of cigarettes daily

Correct answer: C

Rationale: The 42-year-old client who is 50 pounds overweight is at the highest risk for developing diabetes. Excess weight is a significant risk factor for diabetes as it can lead to insulin resistance and metabolic abnormalities. Choices A, B, and D are also risk factors for diabetes, but being overweight has a stronger association with the development of the condition compared to lack of exercise, excessive alcohol consumption, or smoking.
