• PT with active TB. CORRECT ANSWER: Negative airflow room pressure
• Positive finding for guaiac smear on stool specimen. CORRECT ANSWER: Blue
• Adolescent PT plan of care with bacterial infection. CORRECT ANSWER:
Fever- blood cultures
• Motor/expressive aphasia pain scale. CORRECT ANSWER: Numeric
• Mild anxiety symptom. CORRECT ANSWER: Insomnia
• Severe anxiety symptom. CORRECT ANSWER: Nausea
• Sitting down with crutches. CORRECT ANSWER: Both crutches should be in
one hand
• Palliative care. CORRECT ANSWER: A switch from curative treatment to
comfort measures
• Indicator of acute pain. CORRECT ANSWER: Dilated pupils
, • Causes of hypovolemia. CORRECT ANSWER: abnormal gastrointestinal losses-
vomiting, nasogastric suctioning, diarrhea. abnormal skin losses- diaphoresis.
abnormal renal losses- diuretic therapy, diabetes insipidus, renal disease, adrenal
insufficiency, osmotic diuretics. third spacing- peritonitis, intestinal obstruction,
ascitis, burns. hemorrhage. altered intake- NPO.
• causes of dehydration. CORRECT ANSWER: hyperventilation, diabetic
ketoacidosis, enternal feeding without sufficient water intake.
• HCT. CORRECT ANSWER: hypovalemia- increased hct. dehydration- increased
hemoconcentration but not present when dehydration is caused by hemorrhage.
overyhydration- decreased hct= hemodilution
• serum osmolarity. CORRECT ANSWER: dehydration-increased
hemoconcentration osmolarity (>300 mOsm/L-increased protein, BUN,
electrolytes, glucose. overyhydration- decreased hemodilution (osmolarity less
than 270 mOsm/L)
levels: 180-300 mOsm/L.
• urine specific gravity and osmolarity. CORRECT ANSWER: dehydration-
increased concentration
• serum sodium. CORRECT ANSWER: increased hemoconcentration.
hypervolemia- sodium within expected reference range.
levels: 136-145 mEq/L.
• Causes of hypervolemia. CORRECT ANSWER: chronic stimulus to the kidney
to conserve sodium and water (heart failure, cirrhosis, increased
glucocorticosteroids), abnormal renal function with reduced excretion of sodium
and water (renal failure), interstitial to plasma fluid shifts (hypertonic fluids,
