1. After multiple attempts to stop drinking, an adult male is admitted to the medical intensive care unit (MICU) with delirium tremens. He is tachycardic, diaphoretic, restless, and disoriented. Which finding indicates a life-threatening condition?
- A. Widening QRS complexes and flat T waves
- B. Tachycardia and elevated blood pressure
- C. Restlessness and anxiety
- D. Diaphoresis and dehydration
Correct answer: A
Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.
2. When planning care for a 10-year-old child with pneumonia receiving oxygen at 5l/min per nasal cannula, what principle of oxygen administration should the nurse consider?
- A. Avoid administration of oxygen at high levels for extended periods.
- B. Increase oxygen flow rate if the child is still tachypneic.
- C. Reduce oxygen levels gradually after symptoms improve.
- D. Humidify the oxygen to prevent drying of mucous membranes.
Correct answer: A
Rationale: The correct principle of oxygen administration to consider is to avoid administering oxygen at high levels for extended periods. High levels of oxygen for prolonged periods can lead to oxygen toxicity, especially in pediatric patients. Increasing the oxygen flow rate based on tachypnea may not be necessary and can potentially lead to oxygen toxicity. Gradually reducing oxygen levels after symptoms improve may compromise the child's oxygenation. While humidifying oxygen is important to prevent drying of mucous membranes, the primary concern in this case is to avoid high oxygen levels for an extended duration to prevent oxygen toxicity.
3. The charge nurse of the critical care unit informed at the beginning of the shift that a less than optimal number of registered nurses would be working that shift. In planning assignments, which client should receive the most care hours by a registered nurse?
- A. A 34-year-old admitted today after an emergency appendectomy who has a peripheral intravenous catheter and a Foley catheter.
- B. A 48-year-old marathon runner with a central venous catheter experiencing nausea and vomiting due to electrolyte disturbance following a race.
- C. A 63-year-old chain smoker with chronic bronchitis receiving oxygen via nasal cannula and a saline-locked peripheral intravenous catheter.
- D. An 82-year-old client with Alzheimer's disease and a newly fractured femur with a Foley catheter and soft wrist restraints applied.
Correct answer: D
Rationale: The 82-year-old client with Alzheimer's disease and a newly fractured femur should receive the most care hours by a registered nurse because they are at the highest risk for injury and complications. The client's age, diagnosis of Alzheimer's disease, and the presence of a newly fractured femur along with the Foley catheter and wrist restraints indicate a need for close monitoring and care. Choice A is less critical as the client is stable post-appendectomy. Choice B, though experiencing symptoms, is not at the same level of risk as the client in Choice D. Choice C, while requiring oxygen support, does not have the same level of acuity and complexity as the client in Choice D.
4. A client with a postoperative wound that eviscerated yesterday has an elevated temperature. What is the most important intervention for the nurse to implement?
- A. Initiate contact isolation.
- B. Obtain a wound swab for culture and sensitivity.
- C. Assess temperature every 4 hours.
- D. Use alcohol-based solutions for hand hygiene.
Correct answer: B
Rationale: Obtaining a wound swab for culture and sensitivity is the most important intervention in this situation. It helps identify the presence of infection in the postoperative wound that could be causing the elevated temperature. By obtaining a wound swab, healthcare providers can determine the appropriate treatment needed to address any infection. Initiating contact isolation (Choice A) may be necessary in certain situations but is not the priority in this case. Assessing temperature (Choice C) is important but does not directly address the underlying cause of the elevated temperature. Using alcohol-based solutions for hand hygiene (Choice D) is a standard practice for infection control but is not the most crucial intervention in this scenario.
5. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which clinical finding requires immediate intervention?
- A. Oxygen saturation of 90%
- B. Respiratory rate of 24 breaths per minute
- C. Use of accessory muscles
- D. Inspiratory crackles
Correct answer: C
Rationale: The correct answer is C. The use of accessory muscles in a client with COPD indicates increased work of breathing and may signal respiratory failure, requiring immediate intervention. This finding suggests that the patient is struggling to breathe effectively. Oxygen saturation of 90% is low but not critically low, while a respiratory rate of 24 breaths per minute is slightly elevated but not as concerning as the increased work of breathing indicated by the use of accessory muscles. Inspiratory crackles may be present in COPD due to underlying conditions like pneumonia but do not require immediate intervention as the use of accessory muscles does.
