Critical Care Nursing NCLEX Questions

Correct Answer: A

Rationale: The correct answer is A because pain and anxiety trigger the sympathetic nervous system's fight-or-flight response, increasing heart rate, blood pressure, and stress hormones to prepare the body for potential danger. This physiological response helps the individual respond to perceived threats. Choices B, C, and D are incorrect because pain and anxiety typically increase stress levels, do not necessarily remove one from harm, and can hinder rather than enhance performance due to distraction and decreased focus.

Correct Answer: A

Rationale: The correct answer is A: high Fowler's position. This position promotes optimal lung expansion by allowing the chest to expand fully, improving oxygenation. It also helps reduce the work of breathing. Side lying with the head of the bed elevated (B) may not provide the same level of lung expansion. Sitting in a chair (C) may not be suitable for a patient in acute respiratory failure as it may not provide adequate support for breathing. Supine with the bed flat (D) can worsen respiratory distress by limiting lung expansion.

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: 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.
