NCLEX RN Practice Questions Quizlet
1. An 85-year-old client is diagnosed with hypernatremia due to lack of fluid intake and dehydration. The nurse knows that symptoms of hypernatremia include:
- A. Lack of thirst
- B. Pale skin
- C. Hypertension
- D. Swollen tongue
Correct answer: D
Rationale: Hypernatremia among elderly clients can result from dehydration and insufficient fluid intake, leading to sodium levels above 145 mEq/L. Common symptoms of hypernatremia include mental status changes, a thick or swollen tongue, excessive thirst, and flushed skin. Choice A, 'Lack of thirst,' is incorrect as hypernatremia typically presents with excessive thirst. Choice B, 'Pale skin,' is not a typical symptom of hypernatremia. Choice C, 'Hypertension,' is not a direct symptom of hypernatremia and is more commonly associated with other conditions like hypertension itself.
2. 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.
3. The client is being prepared for insertion of a pulmonary artery catheter (Swan-Ganz catheter). What information does the client need to know about the purpose of this catheter insertion?
- A. Stroke volume
- B. Cardiac output
- C. Venous pressure
- D. Left ventricular functioning
Correct answer: D
Rationale: The correct answer is D: Left ventricular functioning. The purpose of inserting a pulmonary artery catheter is to obtain information about left ventricular functioning when the catheter balloon is inflated. Choices A, B, and C are incorrect because while a pulmonary artery catheter can provide information on stroke volume, cardiac output, and venous pressure, its primary purpose is to assess left ventricular function.
4. A client is in the post-anesthesia care unit (PACU) shivering despite being covered with several layers of blankets. What is the nurse's next action?
- A. Turn the client to the prone position
- B. Assist the client in breathing deeply
- C. Administer meperidine as ordered
- D. None of the above
Correct answer: C
Rationale: In the post-anesthesia care unit, clients may experience shivering or chills due to a drop in body temperature after surgery. Meperidine (Demerol) can be prescribed to alleviate shivering in cold clients. The prone position (lying face down) and deep breathing exercises are not interventions specifically indicated for addressing shivering due to low body temperature. Therefore, administering meperidine as ordered is the most appropriate action to manage the client's shivering in this scenario.
5. A patient who has a right-sided chest tube following a thoracotomy has continuous bubbling in the suction-control chamber of the collection device. Which action by the nurse is most appropriate?
- A. Document the presence of continuous bubbling.
- B. Notify the surgeon of a possible pneumothorax.
- C. Take no further action with the collection device.
- D. Adjust the dial on the wall regulator to decrease suction.
Correct answer: C
Rationale: Continuous bubbling in the suction-control chamber of the chest tube collection device is an expected finding and indicates that the suction control chamber is connected to suction. It does not necessarily indicate a large air leak, which would be detected in the water-seal chamber. There is no evidence to suggest a pneumothorax based solely on continuous bubbling in the suction-control chamber. Adjusting the suction level by changing the wall regulator setting is not indicated in this situation, as the amount of suction applied is primarily regulated by the water level in the water-seal chamber and not by the vacuum source. Therefore, the most appropriate action in this scenario is for the nurse to take no further action with the collection device.
