How should the nurse interprets these blood gas values? 2 3
- A. Compensated metabolic alkalosis
- B. Normal values
- C. Uncompensated respiratory acidosis
- D. Uncompensated respiratory alkalosis
Correct Answer: C
Rationale: The correct interpretation is uncompensated respiratory acidosis (Choice C) based on the values. Step 1: Evaluate pH - pH is <7.35, indicating acidosis. Step 2: Determine PaCO2 - PaCO2 is >45 mmHg, indicating respiratory cause. Step 3: Check HCO3- - HCO3- is within normal range, indicating uncompensated state. Choices A, B, and D are incorrect because they do not align with the given blood gas values.

The patient diagnosed with acute respiratory distress synd rome (ARDS) would exhibit which symptom?
- A. Decreasing PaO levels despite increased FiO adminis tration
- B. Elevated alveolar surfactant levels
- C. Increased lung compliance with increased FiO administration 2
- D. Respiratory acidosis associated with hyperventilation
Correct Answer: A
Rationale: The correct answer is A because in ARDS, there is a severe impairment in gas exchange leading to hypoxemia. Decreasing PaO2 levels despite increased FiO2 administration indicate poor oxygenation, a hallmark of ARDS. Elevated alveolar surfactant levels (Choice B) do not directly correlate with ARDS pathophysiology. Increased lung compliance with increased FiO2 administration (Choice C) is not characteristic of ARDS, as ARDS leads to decreased lung compliance. Respiratory acidosis associated with hyperventilation (Choice D) is not a typical finding in ARDS, as hyperventilation is usually present in an attempt to compensate for hypoxemia.
A hospice patient develops a pressure ulcer despite proper repositioning. What should the nurse include in the care plan?
- A. Implement more aggressive wound care strategies.
- B. Ensure adequate hydration and nutrition.
- C. Discuss the prognosis and expected outcomes with the family.
- D. Encourage increased physical activity to improve circulation.
Correct Answer: A
Rationale: The correct answer is A because implementing more aggressive wound care strategies is essential for managing pressure ulcers effectively. This includes proper wound cleaning, debridement, and dressing changes to promote healing. Adequate hydration and nutrition (choice B) are important but may not directly address the pressure ulcer. Discussing prognosis and expected outcomes (choice C) is important but may not directly impact wound healing. Encouraging increased physical activity (choice D) may be contraindicated due to the patient's condition.
The nurse is caring for a mechanically ventilated patient an d responds to a high inspiratory pressure alarm. Recognizing possible causes for the alarma, btihrbe.c nomu/rtesset assesses for which of the following? (Select all that apply.)
- A. Coughing or attempting to talk
- B. Disconnection from the ventilator
- C. Kinks in the ventilator tubing
- D. Need for suctioning
Correct Answer: B
Rationale: The correct answer is B: Disconnection from the ventilator. This is the correct choice because a high inspiratory pressure alarm can indicate a disconnection, leading to inadequate ventilation and increased pressure in the circuit. This can be a life-threatening situation that requires immediate attention.
Explanation of why other choices are incorrect:
A: Coughing or attempting to talk - While coughing or talking may affect the patient's ability to ventilate properly, it is not directly related to the high inspiratory pressure alarm.
C: Kinks in the ventilator tubing - Kinks in the tubing may cause increased resistance to airflow, but they are more likely to trigger a low pressure alarm rather than a high inspiratory pressure alarm.
D: Need for suctioning - Suctioning may be necessary for airway clearance, but it is not directly related to the high inspiratory pressure alarm.
As part of the Synergy Model, the nurse has identified a patient characteristic of resiliency. What patient behavior demonstrates resiliency?
- A. Dysfunctional grieving behaviors after receiving bad news
- B. Developing a list of questions for the physician
- C. Denial of any possible negative outcomes for a procedure
- D. Assigning blame to others for undesired outcomes of illness
Correct Answer: B
Rationale: The correct answer is B because developing a list of questions for the physician shows active engagement in their healthcare, seeking information, and taking control of their situation, which are characteristics of resiliency. This behavior indicates the patient's willingness to understand and cope with their health condition. Choices A, C, and D are incorrect as they demonstrate maladaptive coping mechanisms such as dysfunctional grieving, denial, and blame assignment, which are not indicative of resiliency. Resiliency involves adaptability, problem-solving, and seeking support, which are better exemplified by choice B.
The nurse is caring for a patient in the critical care unit whaobi,r ba.cfotemr/ tebset ing declared brain dead, is being managed by the OPO transplant coordinator. Thir ty minutes into the shift, assessment by the nurse includes a blood pressure 75/50 mm Hg, hear t rate 85 beats/min, and respiratory rate 12 breaths/min via assist/control ventilation. The oxygen saturation (SpO ) is 99% and 2 core temperature 93.8° F. Which primary care provider ord er should the nurse implement first?
- A. Apply forced air warming device to keep temperature > 96.8° F
- B. Obtain basic metabolic panel every 4 hours until surgery
- C. Begin phenylephrine (Neo-Synephrine) for systolic BP < 90 mm Hg
- D. Draw arterial blood gas every 4 hours until surgery
Correct Answer: C
Rationale: The correct answer is C: Begin phenylephrine (Neo-Synephrine) for systolic BP < 90 mm Hg. The nurse should implement this order first because the patient's low blood pressure (75/50 mm Hg) indicates hypotension, which can lead to inadequate perfusion to vital organs. Phenylephrine is a vasoconstrictor that can help increase the patient's blood pressure and improve perfusion. It is crucial to address hypotension promptly to prevent further complications.
Choice A is incorrect because maintaining the patient's temperature above 96.8°F is not the most urgent concern in this scenario. Choice B is incorrect as obtaining a basic metabolic panel every 4 hours is not the immediate priority when the patient is experiencing hypotension. Choice D is incorrect as drawing arterial blood gas every 4 hours is not the most urgent intervention needed to address the patient's low blood pressure.
