Nursing Elites

1. 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.

2. The parent of an infant diagnosed with gastroesophageal reflux disease is receiving feeding instructions from the nurse. Which instruction should the nurse give to the parent to assist in reducing the episodes of emesis?

• A. Provide smaller, more frequent feedings.
• B. Burp the infant frequently during feedings.
• C. Thin the feedings by adding water to the formula.
• D. Thicken the feedings by adding rice cereal to the formula.

Correct answer: D

Rationale: Gastroesophageal reflux disease involves the backward flow of gastric contents into the esophagus due to sphincter issues. To reduce episodes of emesis, it is recommended to thicken feedings by adding rice cereal to the formula. This helps to weigh down the contents in the stomach, making regurgitation less likely. Providing smaller, more frequent feedings and burping the infant frequently are beneficial strategies for gastroesophageal reflux. However, in this case, thickening the feedings is the most appropriate intervention. Thinning the feedings by adding water to the formula is not recommended as it can decrease the caloric density of the formula and may not help in reducing reflux.

3. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?

• A. It is the correct dose
• B. The dose is too low
• C. The dose is too high
• D. The dose should be increased or decreased, depending on the symptoms

Correct answer: B

Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.

4. A patient comes to the emergency department with abdominal pain. Work-up reveals the presence of a rapidly enlarging abdominal aortic aneurysm. Which of the following actions should the nurse expect?

• A. The patient will be admitted to the medicine unit for observation and medication.
• B. The patient will be admitted to the day surgery unit for sclerotherapy.
• C. The patient will be admitted to the surgical unit and resection will be scheduled.
• D. The patient will be discharged home to follow-up with his cardiologist in 24 hours.

Correct answer: C

Rationale: A rapidly enlarging abdominal aortic aneurysm is at significant risk of rupture, which can be life-threatening. The standard treatment for a rapidly enlarging abdominal aortic aneurysm is surgical intervention to prevent rupture. Therefore, the appropriate action for the nurse to expect is that the patient will be admitted to the surgical unit, and resection will be scheduled. Observation and medication (Choice A) are not sufficient for a rapidly enlarging aneurysm, and sclerotherapy (Choice B) is not typically used for aortic aneurysms. Discharging the patient home (Choice D) would be inappropriate and dangerous given the risk of rupture.

5. 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.
