NCLEX RN Exam Review Answers
1. A nurse frequently treats patients in the 72-hour period after a stroke has occurred. The nurse would be most concerned about which of these assessment findings?
- A. INR is 3 seconds long
- B. Heart rate is 110 beats per minute
- C. Intracranial Pressure is 22 mmHg
- D. Blood pressure is 140/80
Correct answer: C
Rationale: The nurse would be most concerned about the assessment finding of an Intracranial Pressure (ICP) reading of 22 mmHg in a patient 72 hours post-stroke. Elevated ICP can indicate increased risk of edema and further brain damage. A target ICP should ideally be maintained at less than or equal to 15-20 mmHg. While the other options may also be important to monitor, an elevated ICP poses a more immediate threat to the patient's neurological status and requires prompt attention.
2. A patient with a history of diabetes mellitus is on the second postoperative day following cholecystectomy. She has complained of nausea and isn't able to eat solid foods. The nurse enters the room to find the patient confused and shaky. Which of the following is the most likely explanation for the patient's symptoms?
- A. Anesthesia reaction
- B. Hyperglycemia
- C. Hypoglycemia
- D. Diabetic ketoacidosis
Correct answer: C
Rationale: In a postoperative diabetic patient who is unable to eat solid foods, the likely cause of symptoms such as confusion and shakiness is hypoglycemia. Confusion and shakiness are common manifestations of hypoglycemia. Insufficient glucose supply to the brain (neuroglycopenia) can lead to confusion, difficulty with concentration, irritability, hallucinations, focal impairments like hemiplegia, and, in severe cases, coma and death. Anesthesia reaction (Choice A) is less likely in this scenario as the patient is already on the second postoperative day. Hyperglycemia (Choice B) is unlikely given the patient's symptoms and history of not eating. Diabetic ketoacidosis (Choice D) typically presents with hyperglycemia, ketosis, and metabolic acidosis, which are not consistent with the patient's current symptoms of confusion and shakiness.
3. While caring for a patient with respiratory disease, the nurse observes that the patient's SpO2 drops from 93% to 88% while the patient is ambulating in the hallway. What is the priority action of the nurse?
- A. Notify the healthcare provider
- B. Document the response to exercise
- C. Administer the PRN supplemental O2
- D. Encourage the patient to pace activity
Correct answer: C
Rationale: The drop in SpO2 to 88% indicates that the patient is hypoxemic and needs supplemental oxygen when exercising. Administering PRN supplemental oxygen is the priority action to correct the hypoxemia and ensure adequate oxygenation during activity. Notifying the healthcare provider can be done after stabilizing the patient's oxygen levels. Documenting the response to exercise is important but secondary to addressing the immediate hypoxemia. Encouraging the patient to pace activity is not sufficient to address the acute drop in SpO2 and provide the necessary oxygen support.
4. The nurse is caring for a client in the late stages of Amyotrophic Lateral Sclerosis (A.L.S.). Which finding would the nurse expect?
- A. Confusion
- B. Loss of half of the visual field
- C. Shallow respirations
- D. Tonic-clonic seizures
Correct answer: C
Rationale: In the late stages of Amyotrophic Lateral Sclerosis (A.L.S.), respiratory muscles are affected, leading to shallow respirations. Confusion is not typically associated with A.L.S. Loss of half of the visual field suggests a neurological issue unrelated to A.L.S., while tonic-clonic seizures are not commonly seen in A.L.S. patients. Shallow respirations are a hallmark sign of respiratory muscle weakness in A.L.S. due to the degeneration of motor neurons.
5. The nurse caring for Mrs. J is prepared to suction her endotracheal tube. Which of the following interventions will reduce hypoxia during this procedure?
- A. Hyperoxygenate Mrs. J for up to 60 seconds prior to starting
- B. Administer 15 mL of sterile fluid into the tube prior to suctioning
- C. Suction for no longer than 30 seconds at a time
- D. Wait 30 seconds after suctioning before attempting again
Correct answer: A
Rationale: Before suctioning a client's endotracheal tube, it is essential to hyperoxygenate the client for approximately 30 to 60 seconds. Hyperoxygenation helps increase oxygen delivery to the tissues, reducing the risk of hypoxia during and after the suctioning procedure. Administering fluid into the tube before suctioning (Choice B) is unnecessary and can lead to complications. Suctioning for no longer than 30 seconds at a time (Choice C) is a general guideline but does not specifically address reducing hypoxia. Waiting 30 seconds after suctioning before attempting again (Choice D) may lead to inadequate oxygenation and potential hypoxia, making it less effective in preventing this complication compared to hyperoxygenation prior to suctioning.
