Critical Care Nursing NCLEX Questions

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: D

Rationale: The correct answer is D: Instill 5 mL of sterile saline into the ET before suctioning. This intervention helps to loosen and mobilize the thick secretions, making them easier to remove during suctioning. It is important to moisten the secretions to prevent mucosal damage and trauma during suctioning. A: Increasing suctioning frequency can lead to mucosal damage and increased risk of infection. B: Repositioning helps with ventilation and preventing pressure injuries, but it does not directly address the thick secretions. C: Adding water to enteral feedings will not directly address the thick secretions in the ET. In summary, instilling sterile saline into the ET before suctioning is the most effective intervention as it helps to loosen and mobilize thick secretions, making suctioning more effective and reducing the risk of mucosal damage.

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 response is C: Your pain medication is already at the highest possible dose. This response acknowledges the patient's pain and reassures them that they are already receiving the maximum safe amount of pain medication. By stating this, the nurse is validating the patient's experience and showing empathy. It is important for the nurse to communicate clearly about the medication to manage the patient's expectations. Choice A is incorrect as it dismisses the patient's pain and can come across as insensitive. Choice B may be well-intentioned but does not address the immediate concern of the patient's pain. Choice D is irrelevant to the patient's statement about pain and does not offer any immediate support or reassurance regarding the pain management.

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.
