Med-surg items on the NCLEX are mostly physiological adaptation: a client with a known condition develops a complication and you decide what happens next. The 156 questions below run across cardiac, respiratory, endocrine, renal, and neuro, and every one of them has a rationale that names the finding that should have moved you. Five are free below.

1 of 5A client with chronic obstructive pulmonary disease has an oxygen saturation of 88% on 2 L/min via nasal cannula and is alert with no distress. What should the nurse do first?
Rationale
In COPD a saturation of 88–92% is the therapeutic target, not an emergency, and this client is alert with no distress. The first action is the independent nursing intervention that is least invasive and most likely to help: sit them up and reassess. Turning the oxygen up to 6 L/min risks blunting the hypoxic drive, and calling rapid response or drawing an ABG escalates ahead of an assessment you have not finished.
Answer: B
A client is admitted with diabetic ketoacidosis. Which findings does the nurse expect? Select all that apply.
Rationale
DKA is hyperglycemia plus ketosis plus metabolic acidosis, and four of these are that picture: Kussmaul respirations blowing off CO₂, ketones on the breath, a glucose well above 250 mg/dL, and dehydration showing as warm, flushed, dry skin. A bicarbonate of 30 mEq/L is above the reference range — in DKA bicarbonate is consumed and falls below 18. On a select-all, check each option against the pathophysiology on its own; there is no partial credit on the real exam.
Answer: A, B, D, E
Four hours after a cardiac catheterization via the right femoral artery, the nurse notes the client's right dorsalis pedis pulse is now faint and the foot is cool and pale. What is the nurse's priority action?
Rationale
A pulse that was present and is now faint, with a cool, pale extremity distal to the puncture site, is arterial occlusion until proven otherwise — a limb-threatening complication that needs the provider now. Documenting and rechecking wastes the window, warming treats the symptom and masks the change, and asking the client to move the ankle neither restores flow nor gives you new information.
Answer: C
A client with heart failure is started on furosemide 40 mg PO daily. Which findings should the nurse report to the provider before administering the next dose? Select all that apply.
Rationale
Furosemide is a loop diuretic, so the two things you are watching are potassium and kidney function. A potassium of 2.9 mEq/L is below the 3.5–5.0 reference range and puts the client at risk for dysrhythmia — hold and report. Muscle cramps with palpitations are the clinical face of that same hypokalemia, so they are reported together, not separately. A creatinine that doubles signals the diuresis has outrun renal perfusion. A blood pressure of 132/78 and a 1 kg loss are the expected response to the drug working, not reasons to hold it.
Answer: A, D, E
A nurse on a medical unit receives report on four clients. Which client should the nurse assess first?
Rationale
Prioritization items are airway, breathing, circulation, in that order — the ranking survives every rewording. Audible gurgling around a fresh tracheostomy is a partially obstructed airway and it is the only option that can kill the client in the next few minutes. Fever, post-op pain, and a glucose of 232 are all real problems that need the nurse, just not first.
Answer: C
