1. 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.

2. The doctor has ordered 1,000 cc of intravenous fluid every 8 hours. You will be using intravenous tubing that delivers 20 cc/drop. At what rate will you adjust the intravenous fluid flow? _____ gtts per minute.

A. 38 gtts/min
B. 42 gtts/min
C. 50 gtts/min
D. 40 gtts/min

Correct answer: D

Rationale: To calculate the rate: 1000 cc/8 hours = 125 cc/hour. 125 cc/hour * 1 drop/20 cc * 1 hour/60 minutes = 40 gtts/min. Therefore, the correct answer is 40 gtts/min. Choice A (38 gtts/min) is incorrect as it doesn't match the calculation result. Choice B (42 gtts/min) is incorrect as it is not the calculated rate. Choice C (50 gtts/min) is incorrect as it is not the calculated rate either.

3. Which type of practice is most similar to research-based practice?

A. Best practices
B. Evidence-based practice
C. Benchmark practices
D. Standard-based practice

Correct answer: B

Rationale: The correct answer is B: Evidence-based practice. Evidence-based practice relies on research to guide clinical decisions, mirroring the approach of research-based practice. Choice A, Best practices, refers to established methods or techniques that are widely accepted as superior. Choice C, Benchmark practices, typically involves setting standards or goals for performance comparison. Choice D, Standard-based practice, usually pertains to adhering to established norms or guidelines.

4. 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.

5. What is the primary focus of primary healthcare?

A. Emergency care
B. Preventive care
C. Specialized treatment
D. Hospital-based services

Correct answer: B

Rationale: The correct answer is B: Preventive care. Primary healthcare emphasizes preventive care, which includes promoting overall health, preventing diseases, and providing early intervention to avoid the progression of illnesses. Emergency care (choice A) is focused on immediate medical attention for urgent health situations but is not the primary focus of primary healthcare. Specialized treatment (choice C) refers to care provided by specialists for specific health conditions, which is not the main focus of primary healthcare. Hospital-based services (choice D) involve inpatient care provided in a hospital setting, which is not the primary focus of primary healthcare that aims to provide comprehensive and accessible care at the community level.
