NCLEX RN Exam Review Answers
1. The nurse reviews the record of a child who is suspected to have glomerulonephritis and expects to note which finding that is associated with this diagnosis?
- A. Hypotension
- B. Brown-colored urine
- C. Low urinary specific gravity
- D. Low blood urea nitrogen level
Correct answer: B
Rationale: Glomerulonephritis refers to a group of kidney disorders characterized by inflammatory injury in the glomerulus. Gross hematuria resulting in dark, smoky, cola-colored, or brown-colored urine is a classic symptom of glomerulonephritis. Hypertension is also common. Blood urea nitrogen levels may be elevated. A moderately elevated to high urinary specific gravity is associated with glomerulonephritis.
2. A fragile 87-year-old female has recently been admitted to the hospital with increased confusion and falls over the last two weeks. She is also noted to have a mild left hemiparesis. Which of the following tests is most likely to be performed?
- A. CBC (Complete Blood Count)
- B. ECG (Electrocardiogram)
- C. Thyroid Function Tests
- D. CT Scan
Correct answer: D
Rationale: A CT scan is most likely to be performed in this scenario. A CT scan would be done to further investigate the cause of the left hemiparesis. Noncontrast CT scanning is commonly used in the acute evaluation of patients with suspected acute stroke to assess for ischemic changes or hemorrhage in the brain. While a CBC may provide information on blood cell counts and general health status, it is not the primary test for evaluating hemiparesis. An ECG is used to assess heart function and rhythm, which is not the main concern in this case. Thyroid function tests evaluate thyroid hormone levels and are not typically the initial tests for evaluating hemiparesis and confusion.
3. What drives respiration in a patient with advanced chronic respiratory failure?
- A. Hypoxemia
- B. Hypocapnia
- C. Hypercapnia
- D. None of the above
Correct answer: A
Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.
4. A client with asthma has low-pitched wheezes present on the final half of exhalation. One hour later the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client
- A. Has increased airway obstruction
- B. Has improved airway obstruction
- C. Needs to be suctioned
- D. Exhibits hyperventilation
Correct answer: B
Rationale: The higher pitched a sound is, the more narrow the airway. Therefore, the obstruction has increased or worsened. With no evidence of secretions, there is no support to indicate the need for suctioning. Wheezes changing from low-pitched to high-pitched and extending throughout exhalation suggest a progression in airway constriction, indicating an increase in airway obstruction. Option B is incorrect because the change in wheezes from low to high pitch does not suggest an improvement in airway obstruction. Option C is incorrect as there is no indication of secretions requiring suctioning. Option D is incorrect as hyperventilation is not typically associated with the described change in wheezes.
5. A patient is being treated in the Neurology Unit for Meningitis. Which of these is a priority assessment for the nurse to make?
- A. Assess the patient for nuchal rigidity
- B. Determine the patient's past exposure to infectious organisms
- C. Check the patient's WBC lab values
- D. Monitor for increased lethargy and drowsiness
Correct answer: D
Rationale: Monitoring for increased lethargy and drowsiness is crucial as these symptoms indicate a decreased level of consciousness, which is the cardinal sign of increased Intracranial Pressure (ICP). Elevated ICP can lead to serious complications and requires immediate intervention. Assessing for nuchal rigidity is important in suspected cases of meningitis but monitoring lethargy and drowsiness takes precedence due to its direct correlation with ICP. Determining past exposure to infectious organisms and checking WBC lab values are important for diagnosing and treating meningitis but do not directly address the immediate concern of increased ICP.
