Critical Care Nursing NCLEX Questions

Correct Answer: B

Rationale: The correct answer is B because assessing the hemofilter every 6 hours for clotting is essential in ensuring the effectiveness of CRRT. Clotting can obstruct blood flow, leading to treatment inefficiency and potential harm to the patient. This step helps the nurse to promptly address any clotting issues and prevent complications. A: Assessing that the blood tubing is warm to the touch is not a standard practice for monitoring CRRT and does not provide relevant information about the treatment's effectiveness. C: Covering the dialysis lines to protect them from light is not a priority in monitoring CRRT. Light exposure is not a common concern in this context. D: Using clean technique during vascular access dressing changes is important for infection prevention but is not directly related to monitoring the effectiveness of CRRT.

Correct Answer: B

Rationale: The correct answer is B: Hypoventilation. A PaCO2 of 48 mm Hg indicates an elevated level of carbon dioxide in the blood, which is typically seen in hypoventilation where the lungs are not effectively removing CO2. Hypoventilation leads to respiratory acidosis. Option A is incorrect because hyperventilation would decrease PaCO2 levels. Option C is incorrect as it does not directly relate to PaCO2 levels. Option D is incorrect as increased excretion of HCO3- would not directly affect PaCO2 levels.

Correct Answer: C

Rationale: Step 1: The objective is for the client to ingest at least 1000 mL of fluid between 7:00 am and 3:30 pm. Step 2: Choice C states that the client drinks 240 mL of fluid five times during the shift, totaling 1200 mL (240 mL x 5) which exceeds the required amount. Step 3: Therefore, choice C is the correct answer as it demonstrates successful achievement of the objective by ensuring the client has ingested enough fluid within the specified time frame. Step 4: Choices A, B, and D are incorrect as they do not directly address the specific objective of fluid intake set for the client. Option A focuses on intake and output, option B relates to abdominal comfort, and option D is about voiding, none of which directly address the specified objective of fluid ingestion.

Correct Answer: C

Rationale: Rationale: - Improved collaboration enhances job satisfaction and reduces burnout, leading to increased staff retention. - Higher staff retention promotes continuity of care, improves team dynamics, and enhances patient outcomes. Summary: - A: Not directly related to collaboration, more about performance evaluation. - B: Manners may improve, but not the most important effect of collaboration. - D: Collaboration involves open communication, so less discussion in front of patients is not a positive outcome.

Correct Answer: A

Rationale: Step 1: Families benefit by witnessing that everything possible was done during resuscitation and invasive procedures. Step 2: This reassures families that healthcare providers are doing their best to save the patient. Step 3: It can provide closure and comfort to families knowing that all efforts were made. Step 4: This transparency can also help in the grieving process for families. Summary: Choice A is correct because it highlights the emotional and psychological benefits for families. Choices B, C, and D are incorrect as they do not align with the positive impacts of allowing family presence during resuscitation and invasive procedures.
