1. Which atrioventricular heart block is also referred to as Mobitz II?

• A. Third-degree atrioventricular heart block
• B. Second-degree atrioventricular heart block
• C. First-degree atrioventricular heart block
• D. Complete heart block

Correct answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

2. A nurse in the emergency department is assessing a client who is unconscious following a motor-vehicle crash. The client requires immediate surgery. Which of the following actions should the nurse take?

• A. Transport the client to the operating room without verifying informed consent
• B. Ask the anesthesiologist to sign the consent
• C. Obtain telephone consent from the facility administrator before the surgery
• D. Delay the surgery until the nurse can obtain informed consent

Correct answer: A

Rationale: In emergency situations where a client is unconscious and requires immediate surgery, implied consent applies. Implied consent allows healthcare providers, including nurses, to proceed with necessary treatment or surgery without formally verifying informed consent. Choice A is correct because the priority in this scenario is to ensure the client receives timely medical intervention to address life-threatening conditions. Choices B, C, and D are incorrect because in emergencies, waiting to obtain formal consent can delay critical treatment, risking the client's health and well-being.

3. Which of the following is considered normal for the neonate?

• A. Chest Circumference: 10 to 13 inches
• B. Length: 16 to 22 inches
• C. Weight: 1,500 to 4,000 g
• D. Head Circumference: 12.6 to 14.5 inches

Correct answer: D

Rationale: A normal head circumference for a neonate typically falls within the range of 12.6 to 14.5 inches. Choice A is incorrect because the chest circumference for a neonate is usually smaller. Choice B is incorrect as the length of a neonate is typically shorter. Choice C is incorrect as the weight of a neonate is usually measured in grams and falls within a different range.

4. 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.

5. 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.
