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: The correct answer is C: Dobutamine infusion. In this scenario, the patient is experiencing hypovolemic shock due to significant blood loss, resulting in low blood pressure, tachycardia, and low cardiac output. Dobutamine is a positive inotropic agent that increases cardiac contractility and output, helping to improve tissue perfusion. Blood transfusion (A) is a common intervention for hypovolemic shock, but in this case, the patient's hematocrit is low, indicating dilutional anemia rather than acute blood loss, so addressing the cardiac output is more urgent. Furosemide (B) is a diuretic that would exacerbate the hypovolemia and worsen the patient's condition. Dopamine (D) is a vasopressor that primarily increases blood pressure, but in this case, the patient's low cardiac output is the main concern, making dobutamine a more appropriate choice.

Correct Answer: A

Rationale: The correct answer is A: A patient with a red tag. In triage, red tags indicate patients with life-threatening injuries who require immediate attention. The nurse must assess this patient first to provide necessary interventions. Patients with blue tags are considered urgent but stable, black tags are deceased or beyond help, and yellow tags are for delayed treatment. Assessing the red-tagged patient first ensures prompt care for those in critical condition.

Correct Answer: C

Rationale: The correct answer is C: Considers factors related to safe patient care. The scenario involves the nurse discussing the patient's living will with the physician, which is essential for ensuring safe patient care by following the patient's preferences. This aligns with the AACN standard of considering factors related to safe patient care, as the nurse is actively involving all relevant parties in decision-making to provide care that is in line with the patient's wishes. Explanation of why other choices are incorrect: A: Acquires and maintains current knowledge of practice - While important, this choice does not directly relate to the scenario where the focus is on safe patient care through communication and collaboration. B: Acts ethically on behalf of the patient and family - While ethics are important, the scenario is more about following the patient's wishes as outlined in the living will rather than making ethical decisions. D: Uses clinical inquiry and integrates research findings in practice - While valuable in nursing practice, this choice does not directly apply to the scenario where

Correct Answer: B

Rationale: The correct answer is B because it acknowledges the partner's feelings while providing information that may help them cope. By stating that unresponsiveness doesn't mean the patient can't hear, the nurse highlights the importance of the partner's presence for emotional support. It encourages the partner to continue visiting, emphasizing their role in providing comfort to the patient. Choice A is incorrect as it dismisses the partner's feelings and lacks empathy. Choice C is incorrect as it implies the nurse will only involve the partner if the patient responds, neglecting the partner's emotional needs. Choice D is incorrect as it deflects responsibility from addressing the partner's concerns and suggests involving other family members without addressing the partner's feelings directly.
