NCLEX RN Exam Review Answers
1. During an assessment of a child admitted to the hospital with a probable diagnosis of nephrotic syndrome, what assessment findings should the nurse expect to observe? Select one that applies.
- A. Proteinuria
- B. Weight gain
- C. Decreased serum lipids
- D. Hematuria
Correct answer: A
Rationale: In nephrotic syndrome, the hallmark finding is massive proteinuria due to increased glomerular permeability. This leads to hypoalbuminemia, resulting in generalized edema. Weight gain, not weight loss, is typically seen due to fluid retention. Serum lipids are elevated, not decreased, in nephrotic syndrome. Hematuria, the presence of blood in the urine, is not a typical finding in nephrotic syndrome.
2. A healthcare professional is putting together a presentation on meningitis. Which of the following microorganisms has not been linked to meningitis in humans?
- A. S. pneumoniae
- B. H. influenzae
- C. N. meningitidis
- D. Cl. difficile
Correct answer: D
Rationale: The correct answer is Cl. difficile. Clostridium difficile (C. diff) is not typically associated with meningitis in humans. This bacterium is known to cause severe diarrhea, usually as a result of antibiotic treatment. S. pneumoniae, H. influenzae, and N. meningitidis are all known to be causative agents of meningitis in humans. S. pneumoniae is a common cause of bacterial meningitis, especially in adults. H. influenzae, particularly type b (Hib), used to be a leading cause of meningitis in children before the introduction of the Hib vaccine. N. meningitidis is another significant pathogen responsible for causing meningitis, especially in young adults and adolescents.
3. The parents of a newborn male with hypospadias want their child circumcised. The best response by the nurse is to inform them that
- A. Circumcision is delayed so the foreskin can be used for the surgical repair
- B. This procedure is contraindicated because of the permanent defect
- C. There is no medical indication for performing a circumcision on any child
- D. The procedure should be performed as soon as the infant is stable
Correct answer: A
Rationale: Circumcision is delayed so the foreskin can be used for the surgical repair. Even if mild hypospadias is suspected, circumcision is not done to save the foreskin for surgical repair if needed. Choice B is incorrect because circumcision is not contraindicated due to a permanent defect; it is delayed for potential surgical needs. Choice C is incorrect as there are situations where a circumcision may be indicated for medical or cultural reasons. Choice D is incorrect because circumcision for hypospadias-related repair is not done immediately but rather delayed to preserve the foreskin for potential reconstructive surgery.
4. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?
- A. Hemoglobin of 11 g/dl
- B. Platelet count of 150,000
- C. INR of 2.5
- D. Potassium of 2.7 mEq/L
Correct answer: D
Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.
5. 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.
