Study Notes
Headache Symptoms
- Headache symptoms can include neurological deficits, fever, photophobia, nausea, vomiting, excessive tearing or redness of the eye, sweating, and nuchal rigidity.
- Nuchal rigidity refers to neck stiffness and can be caused by bacterial meningitis and other serious medical conditions.
CVA Symptoms
- Symptoms of a stroke (CVA) can include sudden, severe headache, numbness, weakness, or loss of motor function on one side of the body, visual difficulties, and dysphagia.
Cranial Nerves
- The twelve cranial nerves are: Olfactory (CN I), Optic (CN II), Oculomotor (CN III), Trochlear (CN IV), Trigeminal (CN V), Abducens (CN VI), Facial (CN VII), Vestibulocochlear (CN VIII), Glossopharyngeal (CN IX), Vagus (CN X), Spinal Accessory (CN XI), and Hypoglossal (CN XII).
- Assessing cranial nerves helps evaluate the function of the brain and the peripheral nervous system.
Assessing Gait and Balance
- Assess muscle size, contour, and involuntary movements.
- Palpate muscles if tenderness, spasm, atrophy, or hypertrophy is suspected.
- Assess balance, gait, and coordination to evaluate cerebellar function.
Assessing Coordination
- Assess coordination by observing the patient's ability to perform simple motor tasks like finger-to-nose testing and heel-to-shin testing.
- Stereognosis tests the patient's ability to identify small objects placed in their hand, which relies on sensory integration.
Assessing Sensory Function
- Assess exteroceptive sensation by testing the patient's ability to feel light touch, pain, temperature, and vibration.
- Assess proprioception by testing the patient's ability to sense the position of their limbs.
Testicular Pain Causes
- Testicular pain can be caused by epididymitis, orchitis, and testicular torsion.
- Epididymitis is an inflammation of the epididymis, a coiled tube on the back of the testicle.
- Orchitis is an inflammation of one or both testicles.
- Testicular torsion is a medical emergency that occurs when the spermatic cord, which connects the testicle to the abdomen, twists.
GU Disorder Diagnostic Tests
- Diagnostic tests for GU disorders include blood tests, routine urinalysis, urine culture and sensitivity, 24-hour collection for protein and creatinine, intravenous pyelography (IVP), fractional excretion of Na+ (FeNa+), glomerular filtration rate (GFR), and prostate-specific antigen test (PSA).
- Fractional excretion of sodium (FeNa+) is a measure of how much sodium is excreted in the urine.
- Glomerular filtration rate (GFR) is a measure of how well the kidneys are filtering waste from the blood.
- Prostate-specific antigen (PSA) test is used to detect prostate cancer.
Common Female Genitourinary Chief Complaints
- Common female GU complaints include pelvic pain, abnormal vaginal bleeding, discharge, lesions, dysuria, hematuria, frequency or urgency, and incontinence.
General Anesthesia Considerations Regarding Renal Function
- General anesthesia can temporarily depress renal blood flow, GFR, urinary flow, and electrolyte excretion.
- The magnitude of this effect is related to the degree of sympathetic block and cardiovascular depression.
- High levels of spinal or epidural anesthesia can impair venous return, diminish cardiac output, and reduce renal perfusion.
Renal Injury Symptoms
- Renal injury can result from intravascular volume depletion and reduced cardiac output.
- Intravascular volume depletion can occur due to hemorrhage, gastrointestinal losses, renal losses, skin and mucous membrane losses, nephrotic syndrome, cirrhosis, and capillary leak.
- Reduced cardiac output can occur due to cardiogenic shock, pericardial diseases, congestive heart failure, and valvular diseases.
Reflexes
- The celiac reflex is a vagal reflex that is elicited by traction on the mesentery or gallbladder or stimulation of the vagus nerve in other areas of the body.
- The Bainbridge reflex (atrial stretch reflex) is a reflex that increases heart rate in response to increased blood volume in the right atrium.
- The Cushing reflex is a reflex that is triggered by increased intracranial pressure and results in hypertension, bradycardia, and irregular respirations.
- The chemoreceptor reflex is a reflex that is triggered by changes in blood oxygen, carbon dioxide, and pH.
- The Bezold-Jarisch reflex is a reflex that is triggered by stimulation of cardiac receptors and results in bradycardia, hypotension, and decreased cardiac output.
