1. A nurse caring for several patients in the cardiac unit is told that one is scheduled for implantation of an automatic internal cardioverter-defibrillator. Which of the following patients is most likely to have this procedure?
- A. A patient admitted for myocardial infarction without cardiac muscle damage.
- B. A postoperative coronary bypass patient, recovering on schedule.
- C. A patient with a history of ventricular tachycardia and syncopal episodes.
- D. A patient with a history of atrial tachycardia and fatigue.
Correct answer: C
Rationale: The correct answer is a patient with a history of ventricular tachycardia and syncopal episodes. An automatic internal cardioverter-defibrillator is used to deliver an electric shock to the heart to terminate episodes of ventricular tachycardia and ventricular fibrillation. These patients are at high risk of life-threatening arrhythmias, which may result in syncope. Patients with atrial tachycardia and fatigue (Choice D) would not typically require an implantable cardioverter-defibrillator as their primary issue is related to atrial arrhythmias. Patients who have had a myocardial infarction without cardiac muscle damage (Choice A) or postoperative coronary bypass patients recovering on schedule (Choice B) are not necessarily at high risk for ventricular arrhythmias and would not be the primary candidates for an implantable cardioverter-defibrillator.
2. Application - The nurse is caring for a patient who has the following labs: Creatinine 2.5mg/dL, WBC 11,000 cells/mL, and Hemoglobin of 12 g/dL. Based on this information, which of these orders would the nurse question?
- A. Administer 30 Units of Lantus Daily
- B. CT of the spine with contrast
- C. X-ray of the abdomen and chest
- D. Administer heparin subcutaneously 5,000 Units every 12 hours
Correct answer: B
Rationale: The correct answer is to question the order for a CT of the spine with contrast. The patient's elevated creatinine level of 2.5mg/dL indicates impaired kidney function. Contrast agents are nephrotoxic and can further compromise kidney function in patients with existing nephropathy. Therefore, it is crucial to avoid contrast-enhanced imaging studies in patients with impaired renal function. Choice A: Administering 30 Units of Lantus Daily is not contraindicated based on the provided lab values. Choice C: Ordering an X-ray of the abdomen and chest is not contraindicated based on the provided lab values. Choice D: Administering heparin subcutaneously at 5,000 Units every 12 hours is not contraindicated based on the provided lab values.
3. Why are subdural hemorrhages more common in the elderly?
- A. Increased anticoagulant use
- B. Increased risk of falls
- C. Brain atrophy
- D. Inconsistent care giving
Correct answer: C
Rationale: Subdural hemorrhages are more common in the elderly due to cerebral atrophy resulting from the natural aging process. This atrophy can lead to the stretching of bridging veins, making them more fragile and prone to tearing even with minor trauma. While increased anticoagulant use and a higher risk of falls are common in the elderly, brain atrophy plays a more direct role in the increased incidence of subdural hemorrhages. Inconsistent caregiving, on the other hand, is not a direct cause of subdural hemorrhages but may impact the overall management and outcome of such cases.
4. A physician suspects a patient may have pancreatitis. Which of the following tests would be most appropriate to diagnose this condition?
- A. CK and Troponin
- B. BUN and Creatinine
- C. Amylase and Lipase
- D. HDL and LDL Cholesterol Levels
Correct answer: C
Rationale: To diagnose pancreatitis, testing amylase and lipase levels is crucial. Amylase and lipase are enzymes produced by the pancreas that help digest carbohydrates and lipids. In pancreatitis, these enzymes are released in high amounts into the bloodstream due to pancreatic inflammation or damage. Elevated levels of amylase and lipase in blood tests strongly indicate pancreatitis. Choice A, CK and Troponin, are cardiac markers used in diagnosing heart conditions like myocardial infarction, not pancreatitis. Choice B, BUN and Creatinine, are kidney function tests, not specific to pancreatitis. Choice D, HDL and LDL Cholesterol Levels, are lipid profile tests used to assess cardiovascular health, not for diagnosing pancreatitis.
5. A 16-month-old child has just been admitted to the hospital. As the nurse assigned to this child enters the hospital room for the first time, the toddler runs to the mother, clings to her, and begins to cry. What would be the initial action by the nurse?
- A. Arrange to change client care assignments
- B. Explain that this behavior is expected
- C. Discuss the appropriate use of 'time-out'
- D. Explain that the child needs extra attention
Correct answer: B
Rationale: When encountering a 16-month-old child exhibiting fear of strangers by clinging to the parent and crying, it is essential for the nurse to explain that this behavior is expected. Fear of strangers typically emerges around 6-8 months of age and can continue into the toddler years and beyond. This behavior is a normal part of development as the child is displaying attachment and trust in familiar caregivers. Changing client care assignments, discussing 'time-out,' or suggesting the child needs extra attention are not appropriate initial actions in this situation. Changing care assignments is unnecessary and does not address the child's emotional needs. Discussing 'time-out' is not relevant as it pertains to discipline strategies for older children. Suggesting the child needs extra attention may misinterpret the situation; the child's behavior is a normal response to a new environment and does not necessarily indicate a need for additional attention.
