After assessing a patient, the nurse will document "PERRLA" in the patient's medical record based upon which finding?

Borborygmi are exaggerated, audible sounds produced by the rapid movement of gas and chyme through the intestinal lumen. These hyperactive bowel sounds often signify increased peristalsis or the early stages of mechanical obstruction. They are commonly associated with hunger or malabsorption syndromes.

A. Loud continual humming bowel sounds: A continuous humming sound in the abdomen is often a venous hum, which can indicate portal hypertension or collateral circulation. It is a vascular sound rather than a result of gastrointestinal motility. It is not defined as borborygmi.

B. Loud gurgling bowel sounds: This is the correct clinical definition of borborygmi. These are the rumbling sounds heard when the bowel is hyperactive. They are easily audible without a stethoscope and reflect high-velocity movement within the digestive tract.

C. Hypoactive bowel sounds: Hypoactive sounds are infrequent and quiet, indicating slowed motility. Borborygmi are by definition loud and hyperactive. Documenting hypoactivity would be the clinical opposite of noting the presence of borborygmi.

D. A peritoneal friction rub: This is a rough, grating sound heard over the liver or spleen during respiration. It indicates inflammation of the peritoneal surface. It is a sign of friction between organs rather than the sound of gas movement.

Lasègue's test, or the straight leg raise, is a provocative maneuver used to identify nerve root irritation, typically at the L4, L5, or S1 levels. Passive elevation of the extended leg stretches the sciatic nerve; a positive result is characterized by reproduction of radicular pain. This finding is highly suggestive of a herniated nucleus pulposus compressing the spinal nerves.

A. Pain is located only in the knee: Discomfort localized to the knee joint during a leg raise usually suggests a primary joint issue, such as a ligamentous tear or meniscus injury. A positive straight leg raise for neurological issues must involve the radiating nerve path. Knee pain alone does not confirm radiculopathy.

B. Pain in the lower back only is noted: While lower back pain can occur during the test, it is not considered a "positive" Lasègue's sign for disc herniation. A positive result specifically requires the reproduction of the patient's radiating leg symptoms. Back pain alone is non-specific and may relate to simple muscle strain.

C. No pain is produced during the test: If the patient can tolerate the leg being raised to 70 degrees without any reproduction of symptoms, the test is documented as negative. This suggests that the sciatic nerve is not being compressed or irritated by a herniated disc. It rules out active nerve root entrapment.

D. Pain radiates down the back of the leg and into the foot: This is the classic positive finding for Lasègue's test. The sharp, shooting pain follows the distribution of the sciatic nerve as it is stretched over a protruding disc. This specific radiating pattern confirms the presence of lumbar nerve root compression.
