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. The patient in the emergency room has a history of alprazolam (Xanax) abuse and abruptly stopped taking Xanax about 24 hours ago. He presents with visible tremors, pacing, fear, impaired concentration, and memory. Which intervention takes priority?

• A. Have the patient lie down on a stretcher with bed rails raised
• B. Offer the patient a cup of water and a small amount of food
• C. Reassure the patient about his well-being
• D. Inform the physician about the patient's Xanax withdrawal

Correct answer: A

Rationale: The 1-4 day period after Xanax withdrawal is critical as it poses the highest risk of life-threatening seizures. Alprazolam is a benzodiazepine, and sudden cessation can lead to severe withdrawal symptoms. The patient's visible tremors, fear, pacing, and cognitive impairment indicate a state of heightened distress and potential seizure risk. Placing the patient on a stretcher with raised bed rails is essential for seizure precautions, ensuring safety and preventing injury during a potential seizure. Offering water and food, reassuring the patient, or informing the physician about Xanax withdrawal are not immediate priorities compared to managing the risk of seizures in this high-risk situation.

3. A patient who has just been admitted with community-acquired pneumococcal pneumonia has a temperature of 101.6�F with a frequent cough and is complaining of severe pleuritic chest pain. Which prescribed medication should the nurse give first?

• A. Codeine
• B. Guaifenesin (Robitussin)
• C. Acetaminophen (Tylenol)
• D. Piperacillin/tazobactam (Zosyn)

Correct answer: D

Rationale: The correct answer is Piperacillin/tazobactam (Zosyn). Early initiation of antibiotic therapy is crucial in cases of community-acquired pneumococcal pneumonia to reduce mortality. While providing symptomatic relief with medications like Codeine for cough, Guaifenesin for mucus clearance, and Acetaminophen for fever and pain is important, the priority should be to start antibiotic therapy to target the underlying infection. Piperacillin/tazobactam is an appropriate choice for treating severe community-acquired pneumonia caused by pneumococcal organisms.

4. A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?

• A. Start an IV so contrast media may be given
• B. Ensure that the patient has been NPO for at least 6 hours.
• C. Inform radiology that a radioactive glucose preparation is needed
• D. Instruct the patient to undress to the waist and remove any metal objects

Correct answer: A

Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.

5. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.
