Critical Care Nursing NCLEX Questions

Correct Answer: B

Rationale: The correct answer is B (80 to 125 mL/min) because this range reflects the normal glomerular filtration rate (GFR) in adults. GFR measures the rate at which blood is filtered by the kidneys, typically around 125 mL/min. A GFR below 60 mL/min indicates kidney dysfunction, making option A incorrect. Option C (125 to 180 mL/min) is above the normal range. Option D (more than 189 mL/min) is too high and could indicate hyperfiltration, common in conditions like diabetes. Therefore, choice B is the most appropriate within the normal GFR range.

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: D

Rationale: The correct answer is D: Identify the problem. This is the first action the nurse should take in the nursing process as it helps in understanding the client's issue. By identifying the problem, the nurse can gather more information through further assessment to determine the underlying cause of the client's difficulty in walking. This step is crucial for developing an effective care plan and interventions. A: Predict the likelihood of the outcome - This choice is not appropriate as predicting the outcome should come after identifying the problem and implementing interventions. B: Consider alternatives - While considering alternatives is important in the decision-making process, it is not the immediate action needed in this scenario. C: Choose the most successful approach - This choice is premature as the nurse needs to first identify the problem before determining the most successful approach.

Correct Answer: D

Rationale: Step 1: Restlessness is an early sign of hypoxemia due to the body's response to low oxygen levels. Step 2: Restlessness occurs as the body tries to increase oxygen intake. Step 3: Other choices are incorrect because clubbing and cyanosis are late signs, while hypotension is not a specific early sign of hypoxemia.

Correct Answer: C

Rationale: The correct answer is C: Suggesting that he meet with the hospital chaplain. This approach is best as it addresses the young man's emotional and spiritual needs during a difficult time. The chaplain can provide comfort, support, and guidance in coping with his girlfriend's situation. This option focuses on holistic care and acknowledges the importance of emotional well-being. A: Recommending that he go home and rest is not the best approach as it dismisses the young man's emotional distress. B: Giving him unrestricted visiting hours with the patient may not be appropriate as it can be overwhelming and may not address his emotional needs effectively. D: Recommending that he ask the doctor to evaluate the patient's pain control measures is important but does not directly address the young man's emotional needs in this situation.
