Nursing Elites

1. The patient's symptoms, lack of antibodies for hepatitis, and the abrupt onset of symptoms suggest toxic hepatitis, which can be caused by commonly used over-the-counter drugs such as acetaminophen (Tylenol). Travel to a foreign country and a history of IV drug use are risk factors for viral hepatitis. Corticosteroid use does not cause the symptoms listed.

• A. Hemoglobin
• B. Temperature
• C. Activity level
• D. Albumin level

Correct answer: D

Rationale: The low oncotic pressure caused by hypoalbuminemia is a major pathophysiologic factor in the development of edema. In this case, monitoring the albumin level is crucial to assess the patient's fluid balance and potential for edema. While hemoglobin, temperature, and activity level are important parameters to monitor in a patient's assessment, they are not directly associated with the patient's current symptoms of toxic hepatitis and edema development. Therefore, the correct choice is the albumin level.

2. 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 compresses plaque against the wall of the diseased coronary artery to improve blood flow. It is performed during a cardiac catheterization to improve coronary artery blood flow in a diseased artery. Surgical repair of a diseased coronary artery is typically done through procedures like aorto-coronary bypass graft (ACBG) rather than PTCA. Placement of an automatic internal cardiac defibrillator (AICD) is a different procedure used for managing cardiac arrhythmias. Non-invasive radiographic examination of the heart refers to procedures like echocardiography or cardiac MRI, not PTCA.

3. After an unimmunized individual is exposed to hepatitis B through a needle-stick injury, which actions will the nurse plan to take (select one that does not apply)?

• A. Administer hepatitis B vaccine.
• B. Test for antibodies to hepatitis B.
• C. Teach about alpha-interferon therapy.
• D. Give hepatitis B immune globulin.

Correct answer: C

Rationale: In the case of exposure to hepatitis B, the nurse should plan to administer hepatitis B vaccine to provide active immunity. Testing for antibodies to hepatitis B is essential to determine the individual's immune status. Giving hepatitis B immune globulin is necessary for passive immunity in cases of exposure. However, teaching about alpha-interferon therapy is not part of the standard management for hepatitis B exposure. Interferon therapy and oral antivirals are typically used in the treatment of chronic hepatitis B infections, not for prophylaxis after exposure.

4. 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.

5. The child with hemolytic-uremic syndrome is anuric and will undergo peritoneal dialysis. Which measure should the nurse implement?

• A. Restrict fluids as prescribed.
• B. Care for the arteriovenous fistula.
• C. Encourage foods high in potassium.
• D. Administer analgesics as prescribed.

Correct answer: A

Rationale: In hemolytic-uremic syndrome, often associated with bacterial toxins and viruses, acute kidney injury occurs in children, leading to symptoms like anemia, thrombocytopenia, renal injury, and CNS symptoms. For an anuric child with hemolytic-uremic syndrome undergoing peritoneal dialysis, fluid restriction is vital to prevent fluid overload. Pain management is not directly related to hemolytic-uremic syndrome. Foods high in potassium should be limited, not encouraged, due to impaired kidney function. Peritoneal dialysis does not involve an arteriovenous fistula, which is specific to hemodialysis.
