Nursing Elites

1. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.

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. Which topic is most important to include in patient teaching for a 41-year-old patient diagnosed with early alcoholic cirrhosis?

• A. Maintaining good nutrition
• B. Avoiding alcohol ingestion
• C. Taking lactulose (Cephulac)
• D. Using vitamin B supplements

Correct answer: B

Rationale: The most important topic to include in patient teaching for a 41-year-old patient diagnosed with early alcoholic cirrhosis is avoiding alcohol ingestion. Alcohol abstinence is crucial in stopping or reversing the progression of the disease. While maintaining good nutrition, taking lactulose (Cephulac), and using vitamin B supplements are important interventions in managing cirrhosis, abstaining from alcohol is the priority for this patient to prevent further damage to the liver and halt disease progression.

4. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is

• A. Surgical repair of a diseased coronary artery.
• B. Placement of an automatic internal cardiac defibrillator.
• C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow.
• D. Non-invasive radiographic examination of the heart.

Correct answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that involves compressing plaque against the wall of a diseased coronary artery to improve blood flow. It is a minimally invasive procedure performed during a cardiac catheterization to open blockages in the coronary arteries. Surgical repair of a diseased coronary artery refers to procedures like coronary artery bypass grafting (CABG), not PTCA. Placement of an automatic internal cardiac defibrillator is a different intervention used for managing cardiac arrhythmias, not for improving coronary blood flow. A non-invasive radiographic examination of the heart would typically refer to procedures like a cardiac CT scan or an MRI, not PTCA.

5. A patient has just been admitted with probable bacterial pneumonia and sepsis. Which order should the nurse implement first?

• A. Performing a chest x-ray via stretcher
• B. Obtaining blood cultures from two sites
• C. Administering Ciprofloxacin (Cipro) 400 mg IV
• D. Inserting an Acetaminophen (Tylenol) rectal suppository

Correct answer: B

Rationale: In a patient with probable bacterial pneumonia and sepsis, the priority intervention is to obtain blood cultures from two sites before initiating antibiotic therapy. This is crucial to identify the causative organism and guide appropriate antibiotic treatment. Administering antibiotics without obtaining cultures first can interfere with accurate results. Performing a chest x-ray and administering acetaminophen can be done after obtaining blood cultures as they are important but not as urgent as identifying the causative organism in sepsis.
