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 nurse is taking the health history of a patient being treated for Emphysema and Chronic Bronchitis. After being told the patient has been smoking cigarettes for 30 years, the nurse expects to note which assessment finding?

• A. Increase in Forced Vital Capacity (FVC)
• B. A widened chest cavity
• C. Clubbed fingers
• D. An increased risk of cardiac failure

Correct answer: C

Rationale: 1. Increase in Forced Vital Capacity (FVC): Forced Vital Capacity is the volume of air exhaled from full inhalation to full exhalation. A patient with COPD would have a decrease in FVC. Therefore, this choice is incorrect. 2. A widened chest cavity: A patient with COPD often presents with a 'barrel chest,' which is seen as a widened chest cavity. Hence, a narrowed chest cavity is not an expected finding. 3. Clubbed fingers - CORRECT: Clubbed fingers are a sign of a long-term, or chronic, decrease in oxygen levels, which is commonly seen in patients with chronic respiratory conditions like Emphysema and Chronic Bronchitis. 4. An increased risk of cardiac failure: Although a patient with these conditions would indeed be at an increased risk for cardiac failure, this is a potential complication and not an assessment finding, making it an incorrect choice.

3. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

4. The nurse is caring for a 2-year-old who is being treated with chelation therapy, calcium disodium edetate, for lead poisoning. The nurse should be alert for which of the following side effects?

• A. Neurotoxicity
• B. Hepatomegaly
• C. Nephrotoxicity
• D. Ototoxicity

Correct answer: C

Rationale: The correct answer is nephrotoxicity. Calcium disodium edetate, used in chelation therapy for lead poisoning, can lead to kidney toxicity. This is an important side effect to monitor in patients undergoing this treatment. Choices A, B, and D are incorrect. Neurotoxicity, hepatomegaly, and ototoxicity are not typically associated with calcium disodium edetate therapy for lead poisoning.

5. The nurse is preparing to care for an infant who has esophageal atresia with tracheoesophageal fistula. Surgery is scheduled to be performed in 1 hour. Intravenous fluids have been initiated, and a nasogastric (NG) tube has been inserted by the primary healthcare provider. The nurse plans care, knowing that which intervention is of highest priority during this preoperative period?

• A. Monitor the temperature.
• B. Monitor the blood pressure.
• C. Reposition the infant frequently.
• D. Aspirate the NG tube every 5 to 10 minutes.

Correct answer: D

Rationale: Esophageal atresia with tracheoesophageal fistula is a critical neonatal surgical emergency. The highest priority intervention during the preoperative period is to aspirate the NG tube every 5 to 10 minutes to keep the proximal pouch clear of secretions and prevent aspiration. This is crucial in reducing the risk of gastric secretions entering the lungs. Repositioning the infant frequently is not as critical as ensuring the NG tube is aspirated. Monitoring the temperature and blood pressure are important nursing interventions but are not the highest priority in this situation. It is essential to prioritize airway protection and prevent aspiration in this neonate undergoing urgent surgical intervention.
