NCLEX RN Exam Review Answers
1. 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.
2. The nurse assesses the chest of a patient with pneumococcal pneumonia. Which finding would the nurse expect?
- A. Increased tactile fremitus
- B. Dry, nonproductive cough
- C. Hyperresonance to percussion
- D. A grating sound on auscultation
Correct answer: A
Rationale: Increased tactile fremitus over the area of pulmonary consolidation is expected with bacterial pneumonias, such as pneumococcal pneumonia. Dullness to percussion would be expected due to consolidation. Pneumococcal pneumonia typically presents with a loose, productive cough rather than a dry, nonproductive cough. Hyperresonance to percussion is not a typical finding in pneumonia and may suggest conditions like emphysema. Adventitious breath sounds such as crackles and wheezes are typical in pneumonia, but a grating sound on auscultation is more representative of a pleural friction rub rather than pneumonia.
3. A 25-year-old male client has been newly diagnosed with hypothyroidism and will take levothyroxine (Synthroid) 50 mcg/day by mouth. As part of the teaching plan, the nurse emphasizes that this medication:
- A. Should be taken in the morning
- B. May increase the client's energy level
- C. Does not need to be stored in a dark container
- D. May increase the client's heart rate
Correct answer: A
Rationale: The correct answer is that levothyroxine (Synthroid) should be taken in the morning. Taking it in the morning can help prevent interference with the client's sleeping pattern, as one of the side effects of levothyroxine is insomnia. Choice B is incorrect because levothyroxine is actually used to treat hypothyroidism and can help increase energy levels. Choice C is incorrect as there is no specific requirement for levothyroxine to be stored in a dark container. Choice D is incorrect because levothyroxine is more likely to increase heart rate rather than decrease it.
4. A teen patient is admitted to the hospital by his physician who suspects a diagnosis of acute glomerulonephritis. Which of the following findings is consistent with this diagnosis? Select one that doesn't apply.
- A. Urine specific gravity of 1.040.
- B. Urine output of 350 ml in 24 hours.
- C. Brown ("tea-colored"?) urine.
- D. Generalized edema.
Correct answer: D
Rationale: The correct answer is 'Generalized edema.' Acute glomerulonephritis typically presents with periorbital edema, not generalized edema. Findings in acute glomerulonephritis include dark, smoky, or tea-colored urine (hematuria) due to red blood cells in the urine, elevated blood pressure, and proteinuria. The urine specific gravity may be high due to decreased urine output, but a urine output of 350 ml in 24 hours is extremely low and suggestive of renal impairment. Generalized edema is more commonly associated with nephrotic syndrome, where there is significant proteinuria leading to hypoalbuminemia and subsequent fluid retention in tissues. In acute glomerulonephritis, the edema is usually limited to the face and lower extremities, not generalized.
5. Application - The nurse is caring for a patient who has the following labs: Creatinine 2.5mg/dL, WBC 11,000 cells/mL, and Hemoglobin of 12 g/dL. Based on this information, which of these orders would the nurse question?
- A. Administer 30 Units of Lantus Daily
- B. CT of the spine with contrast
- C. X-ray of the abdomen and chest
- D. Administer heparin subcutaneously 5,000 Units every 12 hours
Correct answer: B
Rationale: The correct answer is to question the order for a CT of the spine with contrast. The patient's elevated creatinine level of 2.5mg/dL indicates impaired kidney function. Contrast agents are nephrotoxic and can further compromise kidney function in patients with existing nephropathy. Therefore, it is crucial to avoid contrast-enhanced imaging studies in patients with impaired renal function. Choice A: Administering 30 Units of Lantus Daily is not contraindicated based on the provided lab values. Choice C: Ordering an X-ray of the abdomen and chest is not contraindicated based on the provided lab values. Choice D: Administering heparin subcutaneously at 5,000 Units every 12 hours is not contraindicated based on the provided lab values.
