Overview
Patients with [disease name] usually appear [general appearance]. Physical examination of patients with [disease name] is usually remarkable for [finding 1], [finding 2], and [finding 3].
OR
Common physical examination findings of [disease name] include [finding 1], [finding 2], and [finding 3].
OR
The presence of [finding(s)] on physical examination is diagnostic of [disease name].
OR
The presence of [finding(s)] on physical examination is highly suggestive of [disease name].
Physical Examination
- Nausea and malaise are the earliest signs of hyponatremia.
Classification | Clinical signs |
---|---|
Hypervolemic
hyponatremia |
Peripheral edema, ascites, pulmonary edema, raised JVP,clinical signs of underlying causes |
Euvolemic hyponatremia | Clinical signs of underlying causes |
Hypovolemic hyponatremia | Dry mucous membrane, decreased skin turgor, hypotension (orthostatic), tachycardia |
Determination of volume status i.e. dehydration, edema, ascites should be carried out.[29] Patients with clinical signs of volume depletion (e.g. orthostatic decreases in blood pressure and increases in pulse rate, dry mucus membranes, decreased skin turgor) should be considered hypovolemic. When available, direct hemodynamic measurements can provide corroboration of the clinical impression.
- Look for signs of hypothyroidism
- Look for signs of adrenal insufficiency
- Detailed examination to detect any CNS or lung lesion.
Appearance of the Patient
- Patients with hyponatremia may appear with wide range of presentations from no discomfort to severe distress
Vital Signs
- High-grade / low-grade fever
- Hypothermia / hyperthermia may be present
- Tachycardia with regular pulse or (ir)regularly irregular pulse
- Bradycardia with regular pulse or (ir)regularly irregular pulse
- Tachypnea / bradypnea
- Kussmal respirations may be present
- Weak/bounding pulse / pulsus alternans / paradoxical pulse / asymmetric pulse may be present
- High/low blood pressure with normal pulse pressure / wide pulse pressure / narrow pulse pressure may be present
Skin
- Skin examination of patients with hyponatremia varies depend on the underlying causes like hypothyroidism, CHF, adrenal insufficeincy
OR
