Physiological Adaptation Questions
What It Tests
Physiological Adaptation is 11 to 17 percent of the exam, behind only Management of Care and Pharmacological Therapies. NCSBN puts in it alterations in body systems, fluid and electrolyte imbalances, hemodynamics, medical emergencies, illness management, and unexpected responses to therapy. On screen the stem gives a client who is already in trouble, a trend moving the wrong way or a sudden new finding, and asks for the first or priority action.
Rule 1
When the stem shows deterioration, act; another assessment is a delay. A worsening trend or a sudden new finding means the stem has done the assessing for you, so the answer is an intervention. Worked: "A client with COPD whose usual saturation is 89% is now 84%, using accessory muscles. Which action first?" → apply oxygen; the baseline stopped being expected the moment the stem said newly worse.
Rule 2
ABCs pick the first action, and every named emergency has one nurse-initiated first move. The highest failing letter wins, and the emergency's first move needs no order. Worked: "A client with a T4 spinal injury has a pounding headache and a blood pressure of 196/104. Which action first?" → sit the client up; the stem describes autonomic dysreflexia, so its first move is the one you already know.
Rule 3
Treat the client, then the number. When symptoms and a lab value share a stem, the symptom sets the urgency and the option that fixes the client outranks the one that fixes the value. Worked: "A client with a sodium of 118 begins a tonic-clonic seizure. Which action first?" → turn the client onto the side; the seizure is the client and the sodium is the number, so the hypertonic saline waits.
What to Review
Clinical Pearl
Deterioration means act, the ABCs and the named emergency pick the move, and the client comes before the number.
