A 58-year-old client treated with lisinopril brings a home log with readings of 164–172/92–98 mm Hg. In the clinic, the nurse watches the client measure their own pressure: the reading is taken over a sweatshirt right after the client climbed two flights of stairs, with legs crossed and the arm hanging at the side, and the home cuff bladder is too small for the client's upper arm. The client's reading is 168/94 mm Hg. After 5 minutes of quiet seated rest, on a bare arm supported at heart level with a correctly sized cuff, the nurse's readings are 138/82 and 136/80 mm Hg. The client reports no headache, vision changes, or chest pain, and the last two clinic readings with correct technique were 134–140/80–84 mm Hg. Complete the diagram by selecting the condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the client's progress.

Explanation
A small cuff, measurement over clothing, no rest after exertion, crossed legs, and an unsupported arm all raise readings. Correct technique gives values consistent with earlier clinic readings, so the home log is falsely elevated. The nurse corrects the equipment and preparation and then monitors home averages taken with correct technique and the client's return demonstration.
Quick answer Falsely elevated readings from technique errors. Provide a correctly sized cuff and teach 5 minutes of seated rest before readings. Monitor the average of duplicate home readings and a return demonstration of cuff placement.
Why this is correct The same client, measured correctly minutes later, reads 138/82 and 136/80 mm Hg, which matches the last two correct clinic readings. The drop comes from fixing a small cuff, clothing under the cuff, no rest after exercise, crossed legs, and an unsupported arm. No symptoms suggest hypertensive urgency, and white-coat hypertension is the opposite pattern (high in the clinic, normal at home). Fixing the cuff and preparation and then checking technique and the new home averages confirms whether the home log is accurate.
Easy analogy or mental picture A bathroom scale on a soft rug reads heavy. You don't start a diet; you move the scale to a hard floor and weigh again.
Memory hook Fix the cuff and the chair before you fix the dose.
NCLEX decision rule Before acting on an abnormal value, verify that it was measured correctly. Correct the technique and recheck before escalating treatment.
Why the other choices are wrong A dose increase based on an invalid log could cause hypotension. Serum potassium and creatinine track lisinopril effects and kidney function, which a dose change would call for. Ambulatory monitoring is used for suspected white-coat or masked hypertension, but the discrepancy here is already explained by technique. Wrist monitors are more sensitive to position, and upper-arm validated devices are preferred. Retinal findings track long-term target-organ damage, not the accuracy of home readings.

ScenarioA client's home log is high, but the nurse sees multiple technique errors; correct technique produces readings of 138/82 and 136/80 mm Hg, matching prior clinic values.
Cuff bladder size — The inflatable part of the cuff should encircle about 80% of the arm; a cuff that is too small overestimates pressure.
White-coat hypertension — Blood pressure that is elevated in clinical settings but normal outside them.
Home blood-pressure monitoring — Self-measurement with a validated upper-arm device, taking duplicate readings after seated rest.
