Critical Care Nursing Questions and Answers PDF

Correct Answer: C

Rationale: The correct answer is C: notify the provider immediately. The absence of bruit, thrill, and palpable distal pulses in a new arteriovenous fistula suggests potential complications like thrombosis or stenosis, requiring urgent intervention. Notifying the provider promptly allows for timely assessment and appropriate management to prevent further complications. Summary: A: Reassessing the patient in an hour may delay necessary intervention for a potentially serious issue. B: Raising the arm above the level of the patient�s heart does not address the underlying problem and may not improve the situation. D: Applying warm packs to the fistula site is not the appropriate intervention for the absence of bruit and thrill and may not address the underlying cause.

Correct Answer: B

Rationale: The correct answer is B: Dimming lights during the night. This intervention helps reduce stress by creating a more calming environment, promoting rest and sleep. Constant observation (choice A) may increase stress due to lack of privacy. Frequent group rounds (choice C) may disrupt rest. Use of tile floors (choice D) is unrelated to addressing noise and light stress.

Correct Answer: A

Rationale: The correct answer is A: Assessing the patient's level of pain. In this situation, the patient's tachycardia, hypertension, and increased respiratory rate could be indicative of pain. By assessing the patient's pain level, the nurse can address any discomfort the patient may be experiencing, which could be contributing to these physiological responses. Summary of other choices: B: Decreasing the SIMV rate on the ventilator - This is not the priority intervention as the patient's symptoms are more likely related to pain rather than the ventilator settings. C: Providing sedation as ordered - Sedation is not the priority in this case as the patient has been tolerating the ventilator well without requiring sedation. D: Suctioning the patient again - Since the airway has been recently cleared, suctioning again is not necessary at this point and would not address the underlying cause of the patient's symptoms.

Correct Answer: A

Rationale: The correct answer is A: Remove the patient's rings first. This is crucial to prevent constriction and swelling due to potential allergic reactions or inflammation from bee stings. Removing rings allows for proper circulation and prevents complications like compartment syndrome. Ice packs (B) can be applied after removing the rings to reduce swelling. Calamine lotion (C) can provide relief for itching but is not as urgent as ring removal. Diphenhydramine (D) can be given later for systemic allergic reactions but should not take precedence over removing the rings.

Correct Answer: B

Rationale: The correct answer is B: Cluster nursing activities so that the patient has uninterrupted rest periods. Rationale: 1. Clustering nursing activities allows for uninterrupted rest periods, essential for improving sleep quality and addressing disturbed sensory perception. 2. Administering sedatives or opioids (Option A) can lead to drug dependence, tolerance, and adverse effects in older adults. 3. Silencing alarms (Option C) compromises patient safety by impeding timely monitoring and response to critical events. 4. Eliminating assessments (Option D) between 0100 and 0600 disregards the necessity of monitoring vital signs and assessing patient condition around the clock.
