Nursing Elites

1. A 24-year-old female contracts hepatitis from contaminated food. During the acute (icteric) phase of the patient's illness, what would serologic testing most likely reveal?

• A. antibody to hepatitis D (anti-HDV).
• B. hepatitis B surface antigen (HBsAg).
• C. anti-hepatitis A virus immunoglobulin G (anti-HAV IgG).
• D. anti-hepatitis A virus immunoglobulin M (anti-HAV IgM).

Correct answer: D

Rationale: Hepatitis A is primarily transmitted through the oral-fecal route. During the acute phase of hepatitis A, serologic testing typically reveals anti-hepatitis A virus immunoglobulin M (anti-HAV IgM). This antibody appears early in the course of the infection. The presence of anti-HAV IgM indicates an acute infection with hepatitis A. Choices A and B are incorrect as hepatitis D and hepatitis B antigens are not typically associated with acute hepatitis A. Choice C, anti-hepatitis A virus immunoglobulin G (anti-HAV IgG), would indicate a past infection and lifelong immunity, which is not expected during the acute phase of the illness.

2. A client has no pulse or respirations. After calling for help, what should the nurse's first action be?

• A. Start a peripheral IV
• B. Initiate high-quality chest compressions
• C. Establish an airway
• D. Obtain the crash cart

Correct answer: B

Rationale: In a situation where a client has no pulse or respirations, the initial action recommended by the American Heart Association is to start high-quality chest compressions. This action helps maintain blood flow to vital organs such as the brain until normal heart rhythm is restored. Starting CPR with chest compressions before checking the airway and providing rescue breaths is crucial to improve outcomes. While establishing an airway and obtaining a crash cart are important steps in resuscitation, initiating chest compressions takes precedence to ensure oxygenated blood circulation. Starting with chest compressions applies to adults, children, and infants but not newborns.

3. When administering a-interferon and ribavirin (Rebetol) to a patient with chronic hepatitis C, the nurse should monitor for which complication?

• A. Leukopenia.
• B. Hypokalemia.
• C. Polycythemia.
• D. Hypoglycemia.

Correct answer: B

Rationale: When administering a-interferon and ribavirin (Rebetol) for chronic hepatitis C, the nurse should monitor for hypokalemia. This combination therapy is known to cause leukopenia, not polycythemia or hypoglycemia. Hypokalemia is a common electrolyte imbalance that can occur with these medications, making it the correct answer to monitor for in this case.

4. A patient experiences a chest wall contusion as a result of being struck in the chest with a baseball bat. The emergency department nurse would be most concerned if which finding is observed during the initial assessment?

• A. Paradoxic chest movement
• B. Complaint of chest wall pain
• C. Heart rate of 110 beats/minute
• D. Large bruised area on the chest

Correct answer: A

Rationale: Paradoxic chest movement is the most concerning finding as it indicates a potential flail chest, which can lead to severe compromise in gas exchange and rapid hypoxemia. This condition requires immediate attention to prevent respiratory distress. Complaint of chest wall pain, a slightly elevated heart rate, and a large bruised area on the chest are important assessment findings but may not immediately threaten gas exchange or respiratory function. Therefore, identifying paradoxic chest movement is critical for prompt intervention and management.

5. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.
