NCLEX RN Exam Questions
1. The healthcare provider is managing a 20 lbs (9 kg) 6-month-old with a 3-day history of diarrhea, occasional vomiting, and fever. Peripheral intravenous therapy has been initiated, with 5% dextrose in 0.33% normal saline with 20 mEq of potassium per liter infusing at 35 ml/hr. Which finding should be immediately reported to the healthcare provider?
- A. 3 episodes of vomiting in 1 hour.
- B. Periodic crying and irritability.
- C. Vigorous sucking on a pacifier.
- D. No measurable voiding in 4 hours.
Correct answer: D
Rationale: The critical finding that should be reported immediately to the healthcare provider is 'No measurable voiding in 4 hours.' This finding raises concerns about possible hyperkalemia, which can result from continued potassium administration and a decrease in urinary output. Hyperkalemia can lead to serious complications, including cardiac arrhythmias. The management of acute hyperkalemia involves interventions such as administering calcium to protect the heart, shifting potassium into cells, and enhancing potassium elimination from the body. The other choices do not indicate an urgent issue that requires immediate attention. Three episodes of vomiting in 1 hour can be concerning but may not be as immediately critical as the risk of hyperkalemia. Periodic crying and irritability are common in infants and may not indicate a severe complication. Vigorous sucking on a pacifier is a normal behavior in infants and does not signal a medical emergency.
2. 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.
3. The parents of a newborn with a cleft lip are concerned and ask the nurse when the lip will be repaired. With which statement should the nurse respond?
- A. Cleft lip cannot be repaired.
- B. Cleft-lip repair is usually performed by 6 months of age.
- C. Cleft-lip repair is usually performed during the first months of life.
- D. Cleft-lip repair is usually performed between 6 months and 2 years.
Correct answer: C
Rationale: Cleft-lip repair is typically performed during the first few months of life to address functional and cosmetic concerns at an early stage. Early repair can enhance bonding and facilitate feeding. While revisions may be necessary later on, addressing the cleft lip early is essential. Option A is incorrect as cleft lip repair is a common surgical procedure. Option B is incorrect as repair is typically done earlier than 6 months for better outcomes. Option D is incorrect as the usual timing for repair is within the first months of life, not between 6 months and 2 years.
4. A patient's chart indicates a history of ketoacidosis. Which of the following would you not expect to see with this patient if this condition were acute?
- A. Vomiting
- B. Extreme Thirst
- C. Weight gain
- D. Acetone breath smell
Correct answer: C
Rationale: In acute ketoacidosis, a patient typically experiences rapid weight loss due to the body burning fat and muscle for energy in the absence of sufficient insulin. Therefore, weight gain would not be expected. Vomiting may occur due to the metabolic disturbances associated with ketoacidosis. Extreme thirst is a common symptom as the body tries to compensate for dehydration. Acetone breath smell is a classic sign of ketoacidosis as acetone is one of the ketones produced during this condition.
5. The health care provider writes an order for bacteriologic testing for a patient who has a positive tuberculosis skin test. Which action should the nurse take?
- A. Teach about the reason for the blood tests.
- B. Schedule an appointment for a chest x-ray.
- C. Teach about the need to get sputum specimens for 2 to 3 consecutive days.
- D. Instruct the patient to expectorate three specimens as soon as possible.
Correct answer: C
Rationale: The correct action for the nurse to take is to teach the patient about the need to collect sputum specimens for 2 to 3 consecutive days for bacteriologic testing for M. tuberculosis. It is important to obtain these specimens on different days rather than all at once. Blood tests are not used for tuberculosis testing, so teaching about blood tests is not relevant. While a chest x-ray is important in tuberculosis diagnosis, it is not a bacteriologic test. The appearance on a chest x-ray alone is not sufficient to diagnose TB as other diseases can have similar findings.
