Blood pressure increase [Hypertension]:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If you detect sharply elevated blood pressure, quickly rule out possible life-threatening causes. (See Managing elevated blood pressure.)
After ruling out life-threatening causes, complete a more leisurely history and physical examination. Determine if the patient has a history of cardiovascular or cerebrovascular disease, diabetes, or renal disease. Ask about a family history of high blood pressure — a likely finding with essential hypertension, pheochromocytoma, or polycystic kidney disease. Then ask about its onset. Did high blood pressure appear abruptly? Ask the patient's age. The sudden onset of high blood pressure in middle-aged or elderly patients suggests renovascular stenosis. Although essential hypertension may begin in childhood, it typically isn't diagnosed until near age 35. Pheochromocytoma and primary aldosteronism usually occur between ages 40 and 60. If you suspect either, check for orthostatic hypotension. Take the patient's blood pressure with him lying down, sitting, and then standing. Normally, systolic pressure falls and diastolic pressure rises on standing. With orthostatic hypotension, both pressures fall.
Note headache, palpitations, blurred vision, and sweating. Ask about wine-colored urine and decreased urine output; these signs suggest glomerulonephritis, which can cause elevated blood pressure.
Obtain a drug history, including past and present prescriptions, herbal preparations, and over-the-counter drugs (especially decongestants). If the patient is already taking an antihypertensive, determine how well he complies with the regimen. Ask about his perception of elevated blood pressure. How serious does he believe it is? Does he expect drug therapy to help? Explore psychosocial or environmental factors that may impact blood pressure control.
Follow up the history with a thorough physical examination. Using a funduscope, check for intraocular hemorrhage, exudate, and papilledema, which characterize severe hypertension. Perform a thorough cardiovascular assessment. Check for carotid bruits and jugular vein distention. Assess skin color, temperature, and turgor. Palpate peripheral pulses. Auscultate for abnormal heart sounds (gallops, louder second sound, murmurs), rate (bradycardia, tachycardia), or rhythm. Then auscultate for abnormal breath sounds (crackles, wheezing), rate (bradypnea, tachypnea), or rhythm.
Palpate the abdomen for tenderness, masses, or liver enlargement. Auscultate for abdominal bruits. Renal artery stenosis produces bruits over the upper abdomen or in the costovertebral angles. Easily palpable, enlarged kidneys and a large, tender liver suggest polycystic kidney disease. Obtain a urine sample to check for microscopic hematuria.

Blood pressure decrease [Hypotension]:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If the patient is conscious, ask him about associated symptoms. For example, does he feel unusually weak or fatigued? Has he had nausea, vomiting, or dark or bloody stools? Is his vision blurred? Is his gait unsteady? Does he have palpitations? Does he have chest or abdominal pain or difficulty breathing? Has he had episodes of dizziness or fainting? Do these episodes occur when he stands up suddenly? If so, take the patient's blood pressure while he's lying down, sitting, and then standing; compare readings. (See Ensuring accurate blood pressure measurement.) A drop in systolic or diastolic pressure of 10 to 20 mm Hg or more and an increase in heart rate of more than 15 beats/minute between position changes suggest orthostatic hypotension.
Next, continue with a physical examination. Inspect the skin for pallor, sweating, and clamminess. Palpate peripheral pulses. Note paradoxical pulse — an accentuated fall in systolic pressure during inspiration — which suggests pericardial tamponade. Then auscultate for abnormal heart sounds (gallops, murmurs), rate (bradycardia, tachycardia), or rhythm. Auscultate the lungs for abnormal breath sounds (diminished sounds, crackles, wheezing), rate (bradypnea, tachypnea), or rhythm (agonal or Cheyne-Stokes respirations). Look for signs of hemorrhage, including visible bleeding and palpable masses, bruising, and tenderness. Assess the patient for abdominal rigidity and rebound tenderness; auscultate for abnormal bowel sounds. Also, carefully assess the patient for possible sources of infection such as open wounds.

History and physical examination
(Professional Guide to Signs & Symptoms (Fifth Edition))
If you detect sharply elevated blood pressure, quickly rule out possible life-threatening causes. (See Managing elevated blood pressure.)

Determine if the patient has a history of cardiovascular or cerebrovascular disease, diabetes, or renal disease. Ask about a family history of high blood pressure—a likely finding in patients with essential hypertension, pheochromocytoma, or polycystic kidney disease. Then ask about its onset. Did high blood pressure appear abruptly? Ask the patient’s age. Sudden onset of high blood pressure in middle-aged or elderly patients suggests renovascular stenosis. Although essential hypertension may begin in childhood, it typically isn’t diagnosed until near age 35. Pheochromocytoma and primary aldosteronism usually occur between ages 40 and 60. If you suspect either, check for orthostatic hypotension. Take the patient’s blood pressure with him supine, sitting, and then standing. Normally, systolic pressure falls and diastolic pressure rises on standing; in orthostatic hypotension, both pressures fall.
Note headache, palpitations, blurred vision, and sweating. Ask about wine-colored urine and decreased urine output; these signs suggest glomerulonephritis, which can cause elevated blood pressure.
