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 patient is admitted to the emergency department with hypovolemia. Which IV solution should the nurse anticipate administering?

• A. 3% sodium chloride
• B. 10% dextrose in water
• C. 0.45% sodium chloride
• D. Lactated Ringer's solution

Correct answer: D

Rationale: Lactated Ringer's solution is the most suitable IV solution for a patient with hypovolemia. It is a balanced crystalloid solution containing electrolytes such as sodium, chloride, potassium, calcium, and lactate, which closely resemble the body's natural fluids. This solution helps to restore intravascular volume and electrolyte balance in hypovolemic patients. Choice A, 3% sodium chloride, is a hypertonic solution used for specific situations like severe hyponatremia or cerebral edema, not typically for hypovolemia. Choice B, 10% dextrose in water, is a hypertonic solution primarily used for providing calories and free water, not for volume expansion. Choice C, 0.45% sodium chloride, is a hypotonic solution used for conditions like hypernatremia or as maintenance fluid, not for hypovolemia.

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. A client is preparing for an elective mastectomy. The client is wearing a plain gold wedding band. Which of the following is an appropriate procedure for taking care of this client's ring?

• A. Agree to keep the ring for the client until after surgery
• B. Place the ring in the bag with the client's clothing
• C. Tape the ring securely to the client's finger
• D. Place the client's ring in the facility safe

Correct answer: D

Rationale: In this scenario, placing the client's ring in the facility safe is the most appropriate procedure. This ensures the ring is kept secure and prevents any risk of loss or damage during the surgery. Agreeing to keep the ring for the client could raise concerns about accountability, while placing it in the bag with the client's clothing might lead to misplacement. Taping the ring securely to the client's finger is not recommended as it may hinder blood circulation or cause discomfort.

5. Your patient has a blood potassium level of 9.2 mEq/L. What intervention should you anticipate for this patient?

• A. Intravenous potassium supplementation
• B. Intravenous calcium supplementation
• C. Kidney dialysis
• D. Parenteral nutrition

Correct answer: C

Rationale: The correct answer is C: Kidney dialysis. A blood potassium level of 9.2 mEq/L indicates severe hyperkalemia, which can be life-threatening. Kidney dialysis is the most appropriate intervention to rapidly lower potassium levels in this situation. Choice A, intravenous potassium supplementation, would worsen the hyperkalemia. Choice B, intravenous calcium supplementation, is not the primary intervention for hyperkalemia. Choice D, parenteral nutrition, is unrelated to treating hyperkalemia and would not address the immediate concern.
