Hypertension: Home Measurements, Daily Treatment, and Emergency Signs
Teach a treatment target below 130/80 mm Hg unless the provider sets another goal. Obtain 2 home readings 1 minute apart after 5 minutes of seated rest. A systolic reading above 180 or a diastolic reading above 120 mm Hg requires immediate action: call 911 with emergency symptoms, or repeat after at least 1 minute and contact the provider immediately if still elevated without symptoms.
Who needs this teaching
Nonpregnant adults with hypertension and caregivers who assist with home monitoring or medications. Hypertension damages the cardiovascular system, brain, and kidneys without reliable warning symptoms. Pregnancy requires separate blood pressure thresholds and instructions.
The priority teaching points
- Accurate home measurement. Use a validated upper-arm monitor and correctly sized cuff. Avoid caffeine, smoking, and exercise for 30 minutes beforehand. Empty the bladder. Rest quietly for 5 minutes. Sit with the back supported, feet flat, and legs uncrossed. Support the bare arm at heart level. Do not talk.
- Readings and targets. Take 2 readings 1 minute apart at consistent times each day. Record both readings and bring the log and monitor to appointments. The usual treatment target is below 130/80 mm Hg. Normal blood pressure is below 120/80 mm Hg. Follow the client's individualized target.
- DASH eating and sodium. Teach the Dietary Approaches to Stop Hypertension eating pattern: vegetables, fruits, whole grains, legumes, low-fat dairy, and lean proteins. Keep sodium below 2,300 mg daily; 1,500 mg is an appropriate goal for many adults. Check before using potassium supplements or potassium-containing salt substitutes.
- Activity and alcohol. Aim for at least 150 minutes of moderate activity weekly as tolerated. Avoid alcohol for the greatest benefit. For clients who drink, limit intake to no more than 2 standard drinks daily for men or 1 for women. One US standard drink is 12 fl oz of 5% beer, 5 fl oz of 12% wine, or 1.5 fl oz of 40% spirits.
- Daily medications. Take antihypertensive medications as prescribed even without symptoms. Do not stop treatment because readings improve. Report adverse effects instead of changing doses independently.
- Nonprescription products. Ask before using stimulant decongestants or NSAIDs. These drugs increase blood pressure. Review supplements and combination cold products.
- Severely elevated readings. If systolic pressure exceeds 180 or diastolic pressure exceeds 120 mm Hg without symptoms, repeat after at least 1 minute. Contact the provider immediately if it remains elevated. With chest pain, dyspnea, neurologic deficits, or vision changes, call 911 without delaying for another reading.
Red flags the client reports
| Call the provider the same day | Call 911 or the local emergency number |
|---|---|
| Repeated systolic pressure above 180 or diastolic pressure above 120 mm Hg without symptoms: call immediately | Severely elevated pressure with chest pain, dyspnea, severe back pain, or vision changes |
| Persistent medication-related dizziness without syncope | Sudden facial weakness, arm weakness, speech difficulty, or confusion at any pressure |
| Readings repeatedly outside the individualized action limits | Syncope or sudden severe headache with neurologic symptoms |
Teach-back questions
- "Show me your position and cuff placement."
- "How long will you wait between readings?"
- "What is your treatment target?"
- "What will you do if the top number is above 180?"
- "Which symptoms mean you call 911 immediately?"
Teaching tips
- Observe a full return demonstration.
- Write the treatment target and contact number on the handout.
- Explain that either severely elevated number triggers the action plan.
- Use a medication schedule linked to the client's daily routine.

Why this matters for the NCLEX
Teaching is effective when the client states, "I take my medicine even when I feel well," and demonstrates supported positioning with two readings. Statements requiring further teaching include, "Both numbers must be high before I call," and "I will take an extra tablet whenever my pressure rises."
Frequently asked questions
Should the client stop medication when home readings improve?
No. Improved readings indicate treatment effectiveness. Medication changes require the prescriber's instructions.
Must both numbers exceed 180/120 mm Hg to trigger the urgent plan?
No. A systolic reading above 180 or a diastolic reading above 120 triggers the plan.
