Nursing Elites

1. Administration of hepatitis B vaccine to a healthy 18-year-old patient has been effective when a specimen of the patient's blood reveals

• A. HBsAg.
• B. anti-HBs
• C. anti-HBc IgG
• D. anti-HBc IgM.

Correct answer: B

Rationale: The correct answer is 'anti-HBs'. The presence of surface antibody to HBV (anti-HBs) indicates a successful response to the hepatitis B vaccine. Anti-HBs is a marker of immunity and protection against hepatitis B infection. Choices A, C, and D are incorrect because: A) HBsAg indicates current infection with hepatitis B virus, C) anti-HBc IgG suggests past infection or immunity, and D) anti-HBc IgM is a marker of acute hepatitis B infection.

2. Which of the following conditions most commonly causes acute glomerulonephritis?

• A. A congenital condition leading to renal dysfunction.
• B. Prior infection with group A Streptococcus within the past 10-14 days.
• C. Viral infection of the glomeruli.
• D. Nephrotic syndrome.

Correct answer: B

Rationale: Acute glomerulonephritis is most commonly caused by the immune response to a prior upper respiratory infection with group A Streptococcus. Glomerular inflammation occurs about 10-14 days after the infection, resulting in scant, dark urine and retention of body fluid. Periorbital edema and hypertension are common signs at diagnosis.

3. A 36-year-old male patient in the outpatient clinic is diagnosed with acute hepatitis C (HCV) infection. Which action by the nurse is appropriate?

• A. Schedule the patient for HCV genotype testing.
• B. Administer the HCV vaccine and immune globulin.
• C. Teach the patient about ribavirin (Rebetol) treatment.
• D. Explain that the infection will resolve over a few months.

Correct answer: A

Rationale: The correct action by the nurse is to schedule the patient for HCV genotype testing. Genotyping of HCV is crucial in determining the appropriate treatment regimen and guiding therapy decisions. Most patients with acute HCV infection progress to the chronic stage, so it is incorrect to inform the patient that the infection will resolve in a few months. There is no vaccine or immune globulin available for HCV, and ribavirin (Rebetol) is typically used for chronic HCV infection. Therefore, the nurse should prioritize genotyping to assist in treatment planning.

4. A patient with pneumonia has a fever of 101.4 F (38.6 C), a nonproductive cough, and an oxygen saturation of 88%. The patient complains of weakness, fatigue, and needs assistance to get out of bed. Which nursing diagnosis should the nurse assign as the highest priority?

• A. Hyperthermia related to infectious illness
• B. Impaired transfer ability related to weakness
• C. Ineffective airway clearance related to thick secretions
• D. Impaired gas exchange related to respiratory congestion

Correct answer: D

Rationale: The correct answer is 'Impaired gas exchange related to respiratory congestion.' While all the nursing diagnoses are relevant to the patient's condition, the priority should be given to impaired gas exchange due to the patient's low oxygen saturation level of 88%. This indicates a significant risk of hypoxia for all body tissues unless the gas exchange is improved. Addressing impaired gas exchange is crucial to ensure adequate oxygenation and prevent further complications. Hyperthermia, impaired transfer ability, and ineffective airway clearance are important concerns but addressing gas exchange takes precedence in this scenario.

5. The healthcare provider calculates the IV flow rate for a patient receiving lactated Ringer's solution. The patient needs to receive 2000mL of Lactated Ringer's over 36 hours. The IV infusion set has a drop factor of 15 drops per milliliter. How many drops per minute should the healthcare provider set the IV to deliver?

• A. 8
• B. 10
• C. 14
• D. 18

Correct answer: C

Rationale: To determine the drops per minute, we use the formula Drops Per Minute = (Milliliters x Drop Factor) / Time in Minutes. In this case, Drops Per Minute = (2000mL x 15 drops/mL) / (36 hours x 60 minutes/hour) = 30000 / 2160 = 13.89 (approximately 14). Therefore, the correct answer is 14 drops per minute. Choice A (8), Choice B (10), and Choice D (18) are incorrect as they do not correctly calculate the drops per minute based on the given information.
