NUR 3029- EXAM 3 Questions and
Answers Graded A+
Clonus - Correct answer-involuntary muscle contraction/relaxation, often rhythmic
DTR - Correct answer-deep tendon reflex
graded: 0-4
2 is normal
Babinski reflex - Correct answer-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 - Correct answer--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
-Tx: furosemide (lasix), monitor potassium and sodium intake, NPO to limit fluid
intake, replace sodium, daily weight, frequent reorient paitent, fall risk, rails up on
bed, frequent rounding, I&O, frequent neuro assessment, lung sounds bc of
congestion that may occur
Furosemide (Lasix) - Correct answer-diuretic
hemodilution - Correct answer-blood is diluted
-causes Hgb to be low
Sodium and Chloride function - Correct answer-nerve impulse and muscle
contraction

,normal K level - Correct answer-3.5-5 mEq/L
Normal Hgb women - Correct answer-12-15 g/dL
normal Hgb men - Correct answer-14-16.5 g/dL
normal sodium - Correct answer-135-145 mEq/L
normal calcium - Correct answer-8.5-10.5 mg/dL
specific gravity - Correct answer-concentration level
normal range: 1.005-1.030
Normal BUN range - Correct answer-10-20 mg/dL
normal urine osmolarity - Correct answer-500-800 mOsm/kg
H/H - Correct answer-hemoglobin and hematocrit
hypertonic saline - Correct answer-used when Na is VERY low. makes the water
shift outside of the cell
complication: fluid overload
