ATI n300 Med Surg Exam Questions
Extract:
Question 1 of 5
The client presents with a complaint of 'always dropping things and falling down.' During the neurologic assessment, the nurse notices the client is unable to perform rapid alternating movements. Instead the client's response is very slow and misses often. What neurologic dysfunction would the nurse suspect?
Correct Answer: C
Rationale: The cerebellum controls coordination and fine motor movements. Inability to perform rapid alternating movements (dysdiadochokinesia) suggests cerebellar dysfunction.
Question 2 of 5
The nurse is caring for a client, with no other pertinent medical history, who was burned over 70% Total Body Surface Area (TBSA) and weighs 70kg. Using the Parkland Formula, calculate the amount of intravenous fluid required in the first 8 hours after the burn.
Correct Answer: B
Rationale: Using the Parkland Formula:
Total fluid requirement = 4 × 70 kg × 70% TBSA = 19,600 mL (total for 24 hours). Fluids in first 8 hours = 19,600 mL ÷ 2 = 9,800 mL.
Question 3 of 5
The nurse is testing the function of cranial nerve XI (Spinal accessory nerve). Which finding would the nurse expect if the nerve is intact?
Correct Answer: C
Rationale: Cranial nerve XI controls the sternocleidomastoid and trapezius muscles, enabling head turning and shoulder shrugging against resistance.
Question 4 of 5
Which action is safest for the registered nurse (RN) to delegate to the certified nursing assistant (CNA)?
Correct Answer: C
Rationale: Measuring weight is within a CNA's scope of practice and does not require clinical judgment, making it safe to delegate.
Question 5 of 5
The nurse is caring for a client in the burn unit with burns to the head, neck, chest back left arm and hand following an explosion in their garage. Upon admission, the nurse auscultates wheezes throughout all lung fields and applies oxygen via non-rebreather. One hour later, upon reassessment, the patient is visibly anxious and short of breath, wheezes cannot be heard, lung sounds are decreased, voice is hoarse, and the client is coughing up gray sputum. What is the most appropriate nursing action?
Correct Answer: A
Rationale: The absence of wheezes, decreased lung sounds, hoarseness, and gray sputum indicate progressive airway obstruction from inhalation injury, requiring immediate intubation.
