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 manager is reviewing isolation guidelines with a newly licensed nurse. Which of the following statements by the newly licensed nurse indicates understanding of isolation guidelines?

• A. I will have a client who is on airborne precautions wear a mask when out of their room.
• B. I will wear an N95 respirator mask for a client who is on droplet precautions.
• C. I will place a client who has compromised immunity in a negative-pressure airflow room.
• D. I will instruct visitors to wear a mask when visiting a client who is on contact precautions.

Correct answer: A

Rationale: The correct answer is A. Having a client on airborne precautions wear a mask when out of their room is appropriate to prevent the spread of infection. Choice B is incorrect because the healthcare provider, not the client, wears an N95 respirator mask for a client on droplet precautions. Choice C is incorrect because negative-pressure airflow rooms are used for clients with airborne infections, not compromised immunity. Choice D is incorrect because visitors, not clients, should wear a mask when visiting a client on contact precautions.

3. Who is credited with the stages of cognitive development?

• A. Erikson
• B. Piaget
• C. Freud
• D. Lister

Correct answer: B

Rationale: Piaget is indeed credited with the stages of cognitive development. Jean Piaget, a renowned psychologist, proposed a theory of cognitive development that outlines distinct stages through which children develop intellectually. Erikson, Freud, and Lister are not associated with the stages of cognitive development. Erikson is known for his psychosocial stages, Freud for psychosexual stages, and Lister for contributions to the field of medicine.

4. 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.

5. 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.
