NCLEX RN Exam Questions
1. Which of the following interventions should the nurse use when working with a Jackson-Pratt drain?
- A. Strip the tubing to remove clots by milking the tubing back toward the client
- B. Empty the drain when the amount of fluid reaches 25 cc
- C. Strip the tubing to remove clots by milking the tubing away from the client
- D. Maintain the level of the drain above the client's incision
Correct answer: C
Rationale: A Jackson-Pratt drain is a type of active wound drain that may be placed following a surgical procedure. This drain actively draws excess blood and fluid out of the wound. If clots develop within the tubing, the nurse should strip the tubing by milking it in a direction away from the client. This action helps to ensure the drain remains patent and effective. Option A is incorrect because the tubing should be milked away from the client, not towards. Option B is incorrect as the drain should be emptied based on the healthcare provider's orders, not at a fixed volume. Option D is incorrect because the level of the drain should be below the level of the incision to allow drainage by gravity.
2. A 28-year-old male has been found wandering around in a confusing pattern. The male is sweaty and pale. Which of the following tests is most likely to be performed first?
- A. Blood sugar check
- B. CT scan
- C. Blood cultures
- D. Arterial blood gases
Correct answer: A
Rationale: In a 28-year-old male presenting with confusion, sweating, and pallor, the most likely cause is hypoglycemia, especially with no mention of trauma or infection. Therefore, the initial test to be performed should be a blood sugar check to rule out low blood sugar levels. Checking blood sugar levels is crucial in such a scenario as hypoglycemia can lead to altered mental status. A CT scan (choice B) is not typically the initial test for altered mental status without any focal neurological signs or head trauma. Blood cultures (choice C) are more relevant in cases suspected of infection, which is not a primary concern in this scenario. Arterial blood gases (choice D) may be considered later if there are concerns about respiratory status or acid-base disturbances, but in this case, checking the blood sugar level is the most immediate and appropriate action.
3. 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.
4. 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.
5. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?
- A. Narrowed QRS complex
- B. Shortened "PR"? interval
- C. Tall peaked "T"? waves
- D. Prominent "U"? waves
Correct answer: C
Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.
