NCLEX RN Exam Review Answers
1. Mr. C is brought to the hospital with severe burns over 45% of his body. His heart rate is 124 bpm and thready, BP 84/46, respirations 24/minute and shallow. He is apprehensive and restless. Which of the following types of shock is Mr. C at highest risk for?
- A. Septic shock
- B. Hypovolemic shock
- C. Neurogenic shock
- D. Cardiogenic shock
Correct answer: B
Rationale: Mr. C, who has severe burns over 45% of his body, is at highest risk for hypovolemic shock. Burns lead to a loss of plasma volume, reducing the circulating fluid volume and impairing perfusion to vital organs and extremities. In this scenario, the signs of shock, such as increased heart rate, low blood pressure, shallow respirations, and restlessness, indicate a state of hypovolemic shock due to significant fluid loss. Septic shock (choice A) is primarily caused by severe infections, neurogenic shock (choice C) results from spinal cord injuries, and cardiogenic shock (choice D) stems from heart failure. However, in this case, the presentation aligns most closely with hypovolemic shock due to the extensive burn injury and its effects on fluid volume and perfusion.
2. Which finding would necessitate an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy?
- A. Weight loss of 2 lb (1 kg)
- B. Positive urine pregnancy test
- C. Hemoglobin level of 10.4 g/dL
- D. Complaints of nausea and anorexia
Correct answer: B
Rationale: A positive urine pregnancy test would require an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy due to the teratogenic effects of ribavirin. Ribavirin needs to be discontinued immediately to prevent harm to the fetus. The other options, weight loss, hemoglobin level, and complaints of nausea and anorexia, are common adverse effects of the prescribed regimen and may necessitate interventions such as patient education or supportive care, but they would not mandate an immediate cessation of therapy as in the case of a positive pregnancy test.
3. A patient is admitted with active tuberculosis (TB). The nurse should question a healthcare provider's order to discontinue airborne precautions unless which assessment finding is documented?
- A. Chest x-ray shows no upper lobe infiltrates.
- B. TB medications have been taken for 6 months.
- C. Mantoux testing shows an induration of 10 mm.
- D. Three sputum smears for acid-fast bacilli are negative.
Correct answer: D
Rationale: The correct answer is D: Three sputum smears for acid-fast bacilli are negative. Negative sputum smears indicate that Mycobacterium tuberculosis is not present in the sputum, and the patient cannot transmit the bacteria by the airborne route. This finding is crucial for discontinuing airborne precautions. Choice A is incorrect because chest x-rays do not determine the presence of active TB for transmission precautions. Choice B is not directly related to the infectiousness of TB; completing a 6-month course of medication is important for treatment but does not confirm the absence of active disease or infectiousness. Choice C is not relevant to assessing infectiousness; Mantoux testing measures exposure to TB but does not confirm the absence of active infection or infectiousness.
4. Which action should the nurse take to evaluate treatment effectiveness for a patient who has hepatic encephalopathy?
- A. Ask the patient to extend both arms forward.
- B. Request that the patient walk with eyes closed.
- C. Ask the patient to perform the Valsalva maneuver.
- D. Observe the patient's breathing pattern.
Correct answer: B
Rationale: To evaluate treatment effectiveness for a patient with hepatic encephalopathy, requesting the patient to walk with eyes closed is crucial. This test assesses the patient's balance, gait, and coordination, which can be impaired in hepatic encephalopathy due to altered mental status and brain function. Walking with eyes closed challenges the patient's sensory input and proprioception, providing valuable information on improvement or deterioration in neurological function. Asking the patient to extend both arms forward is used to check for asterixis, a sign often seen in hepatic encephalopathy, but it is not specific for evaluating treatment effectiveness. Performing the Valsalva maneuver is unrelated to assessing hepatic encephalopathy and is more commonly used in cardiac evaluations. Observing the patient's breathing pattern may be important in other conditions but is not directly relevant to evaluating treatment effectiveness for hepatic encephalopathy.
5. What intervention should the nurse implement while a client is having a grand mal seizure?
- A. Open the jaw and place a bite block between the teeth
- B. Try to place the client on his side
- C. Restrain the client to prevent injury
- D. Place pillows around the client
Correct answer: B
Rationale: During a grand mal seizure, the client is at risk of injury due to severe, involuntary muscle spasms and contractions. It is crucial for the nurse to avoid restraining the client or inserting objects into their mouth, as these actions may lead to further harm. Placing the client on their side can help facilitate the drainage of oral secretions and assist in maintaining an open airway, reducing the risk of aspiration. Restraint should be avoided as it can exacerbate muscle contractions and increase the risk of injury. Placing pillows around the client may not provide adequate support or protection during the seizure, making it a less effective intervention compared to positioning the client on their side.
