Critical Care Nursing Practice Questions Questions
Question 1 of 5
A nurse wishes to practice using the Synergy Model developed by the American Association of Critical-Care Nurses (AACN). What nursing behavior best supports use of this model?
Correct Answer: B
Rationale: The correct answer is B: Self-directed study of best practice for the patients she cares for. This choice aligns with the Synergy Model by promoting individualized patient care based on best practices. Self-directed study allows the nurse to enhance their knowledge and skills to provide optimal care tailored to each patient's unique needs. Attending mandatory in-service programs (A) may not directly support the individualized care approach. Gathering demographic data (C) is important but not specific to the Synergy Model's focus on patient acuity and nurse competencies. Participating in a research study (D) may contribute to evidence-based practice, but it does not directly relate to the Synergy Model's emphasis on aligning nurse competencies with patient needs.
Question 2 of 5
The nurse is caring for a 48-year-old patient who is intubated and on a ventilator following extensive abdominal surgery. Although the patient is respo nsive, the nurse is not able to read the patient�s lips as the patient attempts to mouth the words. Which of the following assessment tools would be the most appropriate for the nu rse to use when assessing the patient�s pain level? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: The FACES scale. This scale uses facial expressions to assess pain, making it suitable for a patient who is unable to verbalize. The nurse can show the patient a series of faces depicting varying levels of pain and ask them to point to the one that best represents their pain level. This method is non-verbal and easy for patients to understand. The other choices are incorrect: B: The Pain Intensity Scale requires the patient to rate their pain on a numerical scale, which may be difficult for a non-verbal patient. C: The PQRST method is a mnemonic for assessing pain characteristics (provocation, quality, region, severity, timing), but it requires patient communication. D: The Visual Analogue Scale involves marking a point on a line to indicate pain intensity, which is not suitable for a non-verbal patient.
Question 3 of 5
After coronary artery bypass graft surgery a patient is transported to the surgical intensive care unit at noon and placed on mechanical ventilation. How sh ould the nurse interpret the patient�s initial arterial blood gas levels? pH 7.31 PaCO 48 mm Hg Bicarbonate 22 mEq/L PaO 115 mm Hg O saturation 99%
Correct Answer: B
Rationale: The correct answer is B: Partly compensated respiratory acidosis, normal oxygen. The pH of 7.31 indicates acidosis, the PaCO2 of 48 mm Hg shows respiratory acidosis, and the bicarbonate level of 22 mEq/L is slightly elevated, indicating the kidneys are compensating. The PaO2 of 115 mm Hg and oxygen saturation of 99% are normal, ruling out hypoxemia. Therefore, the patient is experiencing partly compensated respiratory acidosis. A: Normal arterial blood gas levels with a high oxygen level - Incorrect. The pH is low, indicating acidosis, which is not normal. C: Uncompensated metabolic acidosis with high oxygen level - Incorrect. Metabolic acidosis would have a primary issue with bicarbonate levels, which is not the case here. D: Uncompensated respiratory acidosis; hyperoxygenated - Incorrect. The oxygen levels are normal, ruling out hyperoxygenation.
Question 4 of 5
Four hours after mechanical ventilation is initiated for a patient with chronic obstructive pulmonary disease (COPD), the patient�s arterial blood gas (ABG) results include a pH of 7.51, PaO2 of 82 mm Hg, PaCO2 of 26 mm Hg, and HCO3 of 23 mEq/L (23 mmol/L). The nurse will anticipate the need to:
Correct Answer: D
Rationale: The correct answer is D: Decrease the respiratory rate. The ABG results show respiratory alkalosis with decreased PaCO2 and elevated pH. This indicates overventilation, so decreasing the respiratory rate will help normalize the PaCO2 and pH levels. Increasing the FIO2 (Choice A) is not needed as the PaO2 is within normal range. Increasing tidal volume (Choice B) can lead to further hyperventilation. Increasing the respiratory rate (Choice C) would exacerbate the respiratory alkalosis.
Question 5 of 5
When assessing an older patient admitted to the emergency department (ED) with a broken arm and facial bruises, the nurse observes several additional bruises in various stages of healing. Which statement or question by the nurse is most appropriate?
Correct Answer: A
Rationale: The correct answer is A: "Do you feel safe in your home?" This question is most appropriate because it directly addresses the potential issue of elder abuse without assuming or accusing the patient. It allows the patient to disclose any safety concerns and initiates a conversation about their well-being. Options B and D are inappropriate as they are accusatory and may escalate the situation. Option C is not as direct and may not effectively address the safety concerns of the patient.
