Critical Care Nursing Questions and Answers PDF Questions
Question 1 of 5
Continuous venovenous hemodialysis is used to
Correct Answer: D
Rationale: The correct answer is D because continuous venovenous hemodialysis combines ultrafiltration, convection, and dialysis techniques. Ultrafiltration removes excess fluid, convection helps in removing solutes, and dialysis involves the diffusion of solutes across a semipermeable membrane. This comprehensive approach ensures effective removal of both fluid and solutes in critically ill patients. Incorrect Answer Analysis: A: Removing fluids and solutes through convection alone is not the complete process in continuous venovenous hemodialysis. B: While volume overload is addressed, continuous venovenous hemodialysis involves more than just removing plasma water. C: Adding dialysate is not the primary method in continuous venovenous hemodialysis; it involves ultrafiltration, convection, and dialysis techniques.
Question 2 of 5
The patient is in the critical care unit and will receive dialysis this morning. The nurse will (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A because evaluating morning lab results is crucial to monitor the patient's condition before dialysis. Abnormal results may impact the dialysis treatment plan. Option B is incorrect as administering antihypertensive medications is not directly related to dialysis. Option C is incorrect as assessing the dialysis access site is the responsibility of the dialysis team. Option D is incorrect as weighing the patient is not typically done immediately before dialysis.
Question 3 of 5
A client with osteoarthritis is given a new prescription for a nonsteroidal anti-inflammatory drug (NSAID). The client asks the nurse, 'How is this medication different from the acetaminophen I have been taking?' Which information about the therapeutic action of NSAIDs should the nurse provide?
Correct Answer: B
Rationale: The correct answer is B: Provide anti-inflammatory response. NSAIDs work by inhibiting the enzyme cyclooxygenase, thereby reducing inflammation, pain, and fever. This is different from acetaminophen, which primarily acts as a pain reliever and fever reducer but lacks significant anti-inflammatory properties. Explanation of why other choices are incorrect: A: Are less expensive - Cost is not related to the therapeutic action of NSAIDs. C: Increase hepatotoxic side effects - While NSAIDs can have adverse effects on the liver, hepatotoxicity is not a primary therapeutic action of these drugs. D: Cause gastrointestinal bleeding - While NSAIDs can increase the risk of gastrointestinal bleeding, this is a potential side effect rather than the primary therapeutic action.
Question 4 of 5
A 16-year-old male client is admitted to the hospital after falling off a bike and sustaining a fractured bone. The healthcare provider explains the surgery needed to immobilize the fracture. Which action should be implemented to obtain a valid informed consent?
Correct Answer: A
Rationale: The correct answer is A: Obtain the permission of the custodial parent for the surgery. In this scenario, the client is a minor (16 years old), which means they are not legally able to provide informed consent for medical procedures. The custodial parent holds legal responsibility for the minor's healthcare decisions. Thus, obtaining the permission of the custodial parent is crucial to ensure valid informed consent. Choice B is incorrect because the non-custodial parent's consent may not be legally required if the custodial parent is available to provide consent. Choice C is incorrect because obtaining consent should precede any administration of medications. Choice D is incorrect as the stepfather's consent may not hold legal weight unless designated as a legal guardian.
Question 5 of 5
Two unlicensed assistive personnel (UAP) are arguing on the unit about who deserves to take a break first. What is the most important basic guideline that the nurse should follow in resolving the conflict?
Correct Answer: D
Rationale: The correct answer is D: Deal with issues and not personalities. This guideline is important because it focuses on resolving the conflict based on the actual problem at hand, rather than personal biases or emotions. By addressing the issues causing the argument, the nurse can help the UAPs find a fair and logical solution. A: Requiring the UAPs to reach a compromise may not address the root cause of the conflict and could lead to further disagreements. B: Weighing the consequences is important but may not be as effective in resolving the conflict as directly addressing the issues. C: Encouraging humor may temporarily diffuse the situation but may not lead to a lasting resolution.
