A 45-year-old postsurgical patient is on a ventilator in the critical care unit has been tolerating the ventilator well and has not required any sedation. The apbairtbi.ecnomt /bteesct omes tachycardic and hypertensive with a respiratory rate that has increased to 28 breaths/min. The ventilator is set on synchronized intermittent mandatory ventilation (SIMV ) at a rate of 10 breaths/min. The patient has been suctioned recently via existing endotracheal tube until airway is clear. When the patient responds appropriately to the nurse’s command s, what should be the nurse’s priority intervention?

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 because it demonstrates effective handoff communication by involving key stakeholders (nephrology consultant physician), requesting specific patient updates, and collaborating on patient care tasks (placing a central line). This scenario promotes continuity of care and ensures important information is shared. Explanation for why other choices are incorrect: B: High noise level disrupts communication and can lead to errors or omissions in handoff information. C: While using a standardized checklist can be beneficial, it alone does not guarantee effective communication if not utilized properly or if key information is missed. D: Conducting reports at the patient's bedside is beneficial for patient involvement but may not address the need for involving relevant healthcare providers like the consultant physician in the handoff process.

Correct Answer: B

Rationale: The correct answer is B: Encouraging family members to make notes of questions they have for the physician during family rounds. This strategy helps families cope with the stress of critical illness by empowering them to stay informed and actively participate in the patient's care. By encouraging them to make notes, it promotes effective communication with the healthcare team and ensures that their concerns and questions are addressed promptly. Other choices are incorrect: A: Asking the family to leave during the morning bath to promote the patient’s privacy is not a helpful strategy for coping with stress as it may lead to feelings of isolation and lack of involvement in the patient's care. C: Providing continuity of nursing care is important but may not directly address the family's coping mechanisms during a critical illness. D: Providing a daily update of the patient’s condition to the family spokesperson is valuable but may not fully address the family's need for active participation and communication with the healthcare team.

Correct Answer: C

Rationale: The correct answer is C: Tachycardia. Hypoxemia results in decreased oxygen levels in the blood, stimulating the body to increase heart rate to improve oxygen delivery. Tachycardia is an early sign of the cardiovascular system compensating for hypoxemia. Heart block (A) is a disruption in the electrical conduction within the heart and is not directly related to hypoxemia. Restlessness (B) is a non-specific sign and can be caused by various factors. Tachypnea (D) is an increased respiratory rate, which is a response to hypoxemia but not a direct effect on the cardiovascular system.

Correct Answer: A

Rationale: Correct Answer: A. Adjust lighting to promote normal sleep-wake cycles. Rationale: 1. Adjusting lighting can help regulate the patient's circadian rhythm, promoting better sleep and reducing stress. 2. Normal sleep-wake cycles are crucial for overall well-being and healing in a critical care setting. 3. Proper lighting can also create a more calming environment for the patient. Summary of Incorrect Choices: B. Providing clocks, calendars, and personal photos can be overwhelming for a stressed patient. C. Talking about other patients may increase anxiety and breach patient confidentiality. D. Telling the day and time of routine interventions may disrupt the patient's sense of time and add to stress.

Correct Answer: B

Rationale: The correct answer is B: Hypoxemia and compensated respiratory acidosis. The patient's pH is within normal range (7.35), indicating compensation. The elevated PaCO2 (55 mm Hg) indicates respiratory acidosis due to inadequate ventilation, likely from COPD. The low PaO2 (65 mm Hg) indicates hypoxemia, common in pneumonia. The normal bicarbonate level (30 mEq/L) suggests metabolic compensation for respiratory acidosis. Choice A is incorrect as there is no metabolic alkalosis present. Choice C is incorrect as the patient has hypoxemia. Choice D is incorrect as the patient is showing compensated respiratory acidosis, not uncompensated.

Correct Answer: B

Rationale: The correct answer is B: The patient may require fluid resuscitation. A decrease in arterial blood pressure during the inspiratory phase of ventilation suggests decreased preload, indicating possible hypovolemia. This can be addressed by administering fluid resuscitation to improve cardiac output and blood pressure. Incorrect Choices: A: The mechanical ventilator is malfunctioning - There is no evidence to suggest a ventilator malfunction based on the arterial pressure change. C: The arterial line may need to be replaced - The arterial line itself is unlikely to cause the observed pressure change. D: The left limb may have reduced perfusion - This is less likely as the pressure change is likely systemic due to decreased preload.

Correct Answer: C

Rationale: The correct answer is C: Cardiac output (CO) of 5 L/min. In cardiogenic shock, the primary goal of using an IABP is to improve cardiac output to ensure adequate perfusion to vital organs. A cardiac output of 5 L/min indicates adequate blood flow and perfusion. Choice A is incorrect as urine output is not a direct indicator of cardiac function. Choice B is incorrect as a heart rate of 110 beats/minute alone does not provide information on the effectiveness of the IABP in improving cardiac output. Choice D is incorrect as stroke volume alone does not provide a comprehensive assessment of overall cardiac function.

Correct Answer: B

Rationale: The correct answer is B because informed consent requires the patient to have knowledge and competence to make a decision. This involves understanding the risks, benefits, and alternatives of the proposed treatment. Choice A is incorrect as it pertains to a physical ability unrelated to decision-making. Choice C is incorrect as consent must be verbal or written, not just nodding. Choice D is incorrect as consent can be obtained in various ways, not specifically through reading and writing in English.
