The nurse assesses a patient who is admitted for an overdo se of sedatives. The nurse expects to find which acid-base alteration?
- A. Hyperventilation and respiratory acidosis
- B. Hypoventilation and respiratory acidosis
- C. Hypoventilation and respiratory alkalosis
- D. Respiratory acidosis and normal oxygen levels
Correct Answer: B
Rationale: The correct answer is B: Hypoventilation and respiratory acidosis. When a patient overdoses on sedatives, it can lead to respiratory depression causing hypoventilation. Hypoventilation results in retention of CO2, leading to respiratory acidosis. This is because the body is not effectively exhaling CO2, causing an increase in carbonic acid levels and a decrease in blood pH. The other choices are incorrect because hyperventilation would lead to respiratory alkalosis (Choice A), hypoventilation does not cause respiratory alkalosis (Choice C), and normal oxygen levels do not indicate the acid-base imbalance caused by sedative overdose (Choice D).

Which intervention is appropriate to assist the patient to co pe with admission to the critical care unit?
- A. Allowing unrestricted visiting by several family members at one time
- B. Explaining all procedures in easy-to-understand terms
- C. Providing back massage and mouth care
- D. Turning down the alarm volume on the cardiac monito r
Correct Answer: B
Rationale: The correct answer is B: Explaining all procedures in easy-to-understand terms. This intervention is appropriate as it helps reduce the patient's anxiety by providing clear information about what to expect during their stay in the critical care unit. This promotes a sense of control and understanding, which can positively impact the patient's coping mechanisms.
A: Allowing unrestricted visiting by several family members at one time may overwhelm the patient and interfere with their rest and recovery.
C: Providing back massage and mouth care may be beneficial but may not directly address the patient's need for information and understanding.
D: Turning down the alarm volume on the cardiac monitor may provide a more comfortable environment but does not address the patient's emotional and psychological needs related to coping with admission to the critical care unit.
A Muslim patient has been admitted to the critical care unit with complications after childbirth. Based on the Synergy Model, which nurse would be the most inappropriate to assign to care for this patient?
- A. New graduate female nurse
- B. Most experienced female nurse
- C. New graduate male nurse
- D. Female nurse with postpartum experience
Correct Answer: C
Rationale: Step-by-step rationale:
1. The Synergy Model emphasizes matching nurse competencies with patient needs.
2. A male nurse may not be culturally appropriate for a Muslim female patient due to religious beliefs.
3. Gender segregation is important in Islamic culture, especially concerning intimate care.
4. Therefore, assigning a new graduate male nurse to care for a Muslim female patient in critical condition is the most inappropriate choice.
Summary:
- Choice A is incorrect because being a new graduate does not impact cultural competence.
- Choice B is incorrect as experience does not necessarily make a nurse the best fit for a specific patient.
- Choice D is incorrect as postpartum experience is relevant, but cultural considerations are more critical in this scenario.
A patient in the ICU is complaining that he is not sleeping well at night because of anxiety. Which of the following would be the most helpful intervention for the nurse to make?
- A. Provide the patient with a bath immediately following his first 90-minute REM sleep cycle.
- B. Increase the patients pain medication.
- C. Provide the patient with 5 minutes of effleurage and then minimize disruptions.
- D. Monitor the patients brain waves by polysomnography to determine his sleep pattern.
Correct Answer: C
Rationale: Rationale:
C: Providing the patient with 5 minutes of effleurage (gentle massage) and minimizing disruptions is the most helpful intervention. Effleurage can help reduce anxiety and promote relaxation, improving sleep quality. Minimizing disruptions creates a conducive environment for sleep.
A: Providing a bath after REM sleep may disrupt the patient's sleep cycle, worsening anxiety.
B: Increasing pain medication may not address the root cause of anxiety and could lead to dependency or side effects.
D: Monitoring brain waves with polysomnography is an invasive procedure not typically indicated for managing anxiety-related sleep issues.
Which of the following are components of the Institute for Healthcare Improvement’s (IHI’s) ventilator bundle? (Select all that apply.)
- A. Interrupt sedation each day to assess readiness to extub aa bit re b.. c om/test
- B. Maintain head of bed at least 30 degrees elevation.
- C. Provide deep vein thrombosis prophylaxis.
- D. Provide prophylaxis for peptic ulcer disease.
Correct Answer: A
Rationale: The correct answer is A because interrupting sedation daily to assess readiness to extubate is a key component of IHI's ventilator bundle to prevent ventilator-associated pneumonia. This practice helps prevent over-sedation, reduce the duration of mechanical ventilation, and decrease the risk of complications. The other choices, B, C, and D, are incorrect as they are not specific components of the IHI's ventilator bundle. Maintaining head of bed elevation, providing deep vein thrombosis prophylaxis, and prophylaxis for peptic ulcer disease are important aspects of critical care but are not directly related to the ventilator bundle protocol outlined by IHI.
Slow continuous ultrafiltration is also known as isolated ultrafiltration and is used to
- A. remove plasma water in cases of volume overload.
- B. remove fluids and solutes through the process of convection.
- C. remove plasma water and solutes by adding dialysate.
- D. combine ultrafiltration, convection, and dialysis.
Correct Answer: A
Rationale: The correct answer is A because slow continuous ultrafiltration removes excess plasma water in cases of volume overload by applying a pressure gradient across a semipermeable membrane. This process helps to achieve fluid balance without removing solutes.
Choice B is incorrect because convection is not the primary mechanism of slow continuous ultrafiltration.
Choice C is incorrect as dialysate is not added in slow continuous ultrafiltration.
Choice D is incorrect as slow continuous ultrafiltration does not combine all three processes of ultrafiltration, convection, and dialysis.
