Critical Care Nursing Practice Questions Questions

Question 1 of 9

The nurse is assessing the exhaled tidal volume (EV ) in a mechanically ventilated patient. T What is the rationale for this assessment?

Correct Answer: D

Rationale: The correct answer is D: Determine the patient’s work of breathing. Assessing the exhaled tidal volume (EV) in a mechanically ventilated patient helps determine how much effort the patient is exerting to breathe. By monitoring the EV, the nurse can evaluate the patient's respiratory status and adjust ventilator settings if needed. It is crucial to ensure that the patient is not working too hard to breathe, as this can lead to respiratory distress. Incorrect answers: A: Assess for tension pneumothorax - Tension pneumothorax is typically assessed through other means such as physical examination and chest X-ray. B: Assess the level of positive end-expiratory pressure - The level of positive end-expiratory pressure is usually set based on the patient's condition and not solely based on the exhaled tidal volume. C: Compare the tidal volume delivered with the tidal volume prescribed - This comparison is important but does not directly relate to assessing the patient's work of breathing.

Question 2 of 9

The patient’s serum creatinine level is 0.7 mg/dL. The expected BUN level should be

Correct Answer: C

Rationale: The correct answer is C (10 to 20 mg/dL). The normal BUN-to-creatinine ratio is approximately 10:1. With a serum creatinine level of 0.7 mg/dL, the expected BUN level should be around 7 to 14 mg/dL. Therefore, choice C (10 to 20 mg/dL) falls within this expected range. Choices A, B, and D are incorrect as they do not align with the typical BUN-to-creatinine ratio and would indicate abnormal kidney function.

Question 3 of 9

What is the best way to monitor agitation and effectivenes s of treating it in the critically ill patient?

Correct Answer: D

Rationale: The correct answer is D: Richmond Agitation Sedation Scale (RASS). RASS is specifically designed to monitor agitation and sedation levels in critically ill patients, providing a standardized and objective assessment. It includes clear descriptors for different levels of agitation and sedation, allowing for consistent monitoring and treatment adjustments. CAM-ICU is mainly used for delirium assessment, not agitation. FACES assessment tool is more appropriate for pain assessment. Glasgow Coma Scale is focused on assessing level of consciousness, not agitation specifically. By using RASS, healthcare providers can accurately track agitation levels and evaluate the effectiveness of interventions in managing agitation in critically ill patients.

Question 4 of 9

A male client who has been taking propranolol (Inderal) for 18 months tells the nurse that the healthcare provider discontinued the medication because his blood pressure has been normal for the past three months. Which instruction should the nurse provide?

Correct Answer: D

Rationale: The correct answer is D: Ask the healthcare provider about tapering the drug dose over the next week. This answer is correct because propranolol is a beta-blocker, and abrupt discontinuation can lead to rebound hypertension, angina, or even myocardial infarction due to the sudden withdrawal of the medication. Tapering the drug dose over time allows the body to adjust gradually and reduces the risk of these adverse effects. Choice A is incorrect because obtaining another antihypertensive prescription is not necessary if the client's blood pressure has been normal for the past three months. Choice B is incorrect because abruptly stopping the medication without tapering can lead to withdrawal symptoms. Choice C is incorrect because simply reporting uncomfortable symptoms without taking appropriate action (tapering the drug dose) is not addressing the potential risks associated with abrupt discontinuation of propranolol.

Question 5 of 9

What were the findings of the Study to Understand Progno ses and Preferences for Outcomes and Risks of Treatment (SUPPORT)?

Correct Answer: C

Rationale: The correct answer is C because the SUPPORT study revealed disparities between patients' care preferences and the actual care provided. This is supported by the findings that many patients did not receive treatments aligned with their preferences. Choice A is incorrect because the study actually highlighted communication challenges between patients and healthcare providers. Choice B is incorrect as the study showed that critical care units often do not meet the needs of dying patients and their families. Choice D is incorrect as the study found that pain and suffering of patients at the end of life are not always well controlled in hospitals.

Question 6 of 9

Assuming each of these patients was discharged from the hospital, which older adult patient is at greatest risk for decreased functional status and quality of life?

Correct Answer: A

Rationale: The correct answer is A because this patient had a complex surgery with complications, requiring long-term care and loss of a significant other, which can impact their emotional well-being and support system. This can lead to decreased functional status and quality of life. Choice B is incorrect as the patient has support from a spouse and manages health care independently, indicating a good support system. Choice C is incorrect as the patient is cognitively intact and social, which suggests a good quality of life. Choice D is incorrect as the patient had a less complex procedure, well-managed diabetes, and was living independently, which indicates a lower risk for decreased functional status and quality of life compared to choice A.

Question 7 of 9

A patient who is orally intubated and receiving mechanical ventilation is anxious and is fighting the ventilator. Which action should the nurse take next?

Correct Answer: A

Rationale: The correct answer is A: Verbally coach the patient to breathe with the ventilator. This approach allows the nurse to address the patient's anxiety and help them synchronize their breathing with the ventilator, promoting better ventilation and oxygenation. It is important to first try non-invasive interventions before resorting to sedation or manual ventilation. Sedating the patient (B) should be a last resort to avoid potential complications. Manual ventilation (C) may disrupt the ventilator settings and cause respiratory distress. Increasing the rate of propofol infusion (D) is not indicated unless the patient's sedation level is inadequate.

Question 8 of 9

Family members are in the patient’s room when the patient has a cardiac arrest and the staff starts resuscitation measures. Which action should the nurse take next?

Correct Answer: C

Rationale: The correct answer is C because it involves patient-centered care and respects the family's preferences. By asking the family members whether they would prefer to remain in the patient's room or wait outside, the nurse acknowledges their needs and allows them to make an informed decision based on their comfort level. This empowers the family members and promotes a supportive environment during a stressful situation. Choice A is incorrect because it assumes that keeping the family in the room without their input is the best approach, which may not be the case for all families. Choice B is incorrect because asking the family to wait outside without considering their preferences may not be the most supportive action. Choice D is incorrect because it makes a blanket statement about patient comfort without considering individual family dynamics and preferences.

Question 9 of 9

A family of a young girl who has been diagnosed with leukemia has travelled 12 hours by car to admit her to the ICU and be with her during her treatment. Which aspect of the critical care family assistance program would most likely be needed by this family initially?

Correct Answer: C

Rationale: The correct answer is C: Hospitality programs. Given the family's long journey and the stressful situation of having a child diagnosed with leukemia, their immediate need would likely be for accommodations and support services provided by hospitality programs, such as lodging, meals, transportation assistance, and emotional support. This would help alleviate the burden of their travel and allow them to focus on being with their daughter in the ICU. Incorrect answers: A: Educational materials - While education is crucial for families, it may not be the most immediate need in this situation. B: Weekly group family information sessions - These sessions may be helpful for support and information-sharing, but they are not as urgent as addressing the family's immediate needs. D: Pet therapy - While pet therapy can provide emotional support, it may not be the most pressing need for this family at the moment.
