Clonus Ans: involuntary muscle contraction/relaxation, often
rhythmic
DTR Ans: deep tendon reflex
graded: 0-4
2 is normal
Babinski reflex Ans: Reflex in which a newborn fans out the toes
when the sole of the foot is stroked with relfex hammer
-normal for adults NOT to experience this (- result)
-abnormal: adult foot shows fanning= sign of meningitis(+ result)
Case Study: Mary Ans: -old lady drank a lot of pool water
-S/S: lethargic, very thirsty,
-labs: very low serum Na, Cl is slightly low, K and Hgb are also low
-other Dx tests: BUN (low), urinalysis (sodium osmolarity and
specific gravity are high)
-Dx: 1. disturbed thought processes related to electrolyte and fluid
imbalances. 2. Noncompliance with medication (she hasnt been
taking her antipsychotic drugs). 3. Excess fluid volume deficit
