NCLEX RN Exam Questions
1. Following a diagnosis of acute glomerulonephritis (AGN) in their 6-year-old child, the parent's remark: "We just don't know how he caught the disease!"? The nurse's response is based on an understanding that:
- A. AGN is a streptococcal infection that involves the kidney tubules.
- B. The disease is easily transmissible in schools and camps.
- C. The illness is usually associated with chronic respiratory infections.
- D. It is not "caught"? but is a response to a previous B-hemolytic strep infection.
Correct answer: D
Rationale: The correct answer is that acute glomerulonephritis (AGN) is not 'caught' but is a response to a previous B-hemolytic strep infection. AGN is generally accepted as an immune-complex disease triggered by an antecedent streptococcal infection occurring 4 to 6 weeks prior. It is considered a noninfectious renal disease. Choice A is incorrect because AGN is not a streptococcal infection that involves the kidney tubules but rather a noninfectious renal disease. Choice B is incorrect as AGN is not easily transmissible in schools and camps but is a result of a previous streptococcal infection. Choice C is incorrect as AGN is not usually associated with chronic respiratory infections, but with a previous streptococcal infection.
2. A patient with right lower-lobe pneumonia has been treated with IV antibiotics for 3 days. Which assessment data obtained by the nurse indicates that the treatment has been effective?
- A. Bronchial breath sounds are heard at the right base.
- B. The patient coughs up small amounts of green mucus.
- C. The patients white blood cell (WBC) count is 9000/L
- D. Increased tactile fremitus is palpable over the right chest
Correct answer: C
Rationale: The normal WBC count indicates that the antibiotics have been effective. All the other data suggest that a change in treatment is needed.
3. A 23-year-old has been admitted with acute liver failure. Which assessment data are most important for the nurse to communicate to the healthcare provider?
- A. Asterixis and lethargy
- B. Jaundiced sclera and skin
- C. Elevated total bilirubin level
- D. Liver 3 cm below costal margin
Correct answer: A
Rationale: The most critical assessment data for the nurse to communicate to the healthcare provider in a patient with acute liver failure are asterixis and lethargy. These findings are indicative of grade 2 hepatic encephalopathy, which signals a rapid deterioration in the patient's condition, necessitating early transfer to a transplant center. Jaundiced sclera and skin, elevated total bilirubin level, and a liver 3 cm below the costal margin are all typical findings in hepatic failure but do not indicate an immediate need for a change in the therapeutic plan. Therefore, while these findings are relevant and should be reported, they are not as urgent as asterixis and lethargy in a patient with acute liver failure.
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 client is admitted for a head injury. His body is lying in an abnormal position and the physician states he is exhibiting decorticate posturing. Based on this assessment, the nurse can expect to find the client with:
- A. The legs extended and rotated internally; the elbow, wrists, and fingers flexed
- B. The legs pulled toward the chest; the head bent back at a 30-degree angle
- C. The back arched; the arms and legs extended and rigid
- D. The legs extended and rotated externally; the head turned to the right or the left
Correct answer: A
Rationale: Decorticate posturing is indicative of an injury to the corticospinal tract, resulting in abnormal posturing. It may occur spontaneously or in response to stimulation. This posture involves the legs being extended and rotated internally, while the elbows, wrists, and fingers are flexed inward. Choice A is correct because it accurately describes the expected positioning associated with decorticate posturing. Choices B, C, and D are incorrect. Choice B describes a different type of posturing known as opisthotonos. Choice C describes an exaggerated arching of the back, which is not characteristic of decorticate posturing. Choice D describes a different type of posturing with external rotation of the legs and head turning to the side, not consistent with decorticate posturing.
