Critical Care Nursing NCLEX Questions

Correct Answer: B

Rationale: The correct answer is B because a mechanically ventilated patient with cardiogenic shock being treated with an intra-aortic balloon pump would benefit most from having a Vigileo pulse contour cardiac output monitoring system. This device provides continuous cardiac output monitoring and can help guide hemodynamic management in critically ill patients, especially those with hemodynamic instability like cardiogenic shock. It allows for real-time adjustments of fluid and vasoactive medications to optimize cardiac output and tissue perfusion. Choice A is incorrect because a patient with a history of aortic insufficiency and postoperative myocardial infarction may not require continuous cardiac output monitoring like the patient in choice B. Choice C is incorrect as the patient with atrial fibrillation and paroxysmal supraventricular tachycardia does not necessarily need cardiac output monitoring. Choice D is also incorrect as a mechanically ventilated patient following repair of an acute bowel obstruction may not require continuous cardiac output monitoring unless there are specific complications.

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: 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.

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: D

Rationale: The Venturi mask is the best choice for delivering 65% oxygen because it allows precise oxygen concentration delivery through adjustable venturi valves. This device ensures consistent oxygen levels even during variations in patient breathing patterns. Face mask with non-rebreathing reservoir (A) delivers higher oxygen concentrations, low-flow nasal cannula (B) is not suitable for precise oxygen delivery, and simple face mask (C) may not provide the desired oxygen concentration.
