What are s/sx of flail chest? - ANSWER✔ paradoxical movement of the chest
wall, crepitus, hypoxemia, extreme pain with inspiration and expiration
What are some nursing cares for patients suffering from flail chest? -
ANSWER✔ assess breathing pattern, auscultate lung sounds, monitor
oxygenation status, may require mechanical ventilation
What oxygen device would be used for a patient who is retaining CO2? -
ANSWER✔ Venturi mask
What are s/sx of hypoglycemia? - ANSWER✔ sweating, tremors, hunger,
confusion, slurred speech, seizures
How do we treat hypoglycemia? - ANSWER✔ If conscious:
-3 to 4 glucose tablets or 4 to 6 ounces of juice
If unconscious:
-subcutaneous or intramuscular glucagon or 25-50 mL D50 IV
What are some concerns with hyperglycemia s/p surgery? - ANSWER✔ surgery
can trigger a stress response which increases blood glucose levels
treat with IV insulin until controlled at <180 mg/dL
What are s/sx of Diabetes Insipidus (DI)? - ANSWER✔ polyuria (>3L/day lost)
polydipsia (2-20L of fluid/day)
What are lab results expected for patient with DI? - ANSWER✔ Electrolytes
are usually elevated
Specific gravity = 1.001-1.005
, Fluid deprivation test:
-urine production
-electrolyte levels
-weight
Vasopressin test:
-urine osmolality 30-60 minutes after subcutaneous injection of vasopressin
What are s/sx of SIADH? - ANSWER✔ hyponatremia
What are the s/sx of 2nd degree heart block Mobitz I (Wenckebach)? -
ANSWER✔ most don't experience symptoms
if they do, usually is lightheadedness and dizziness
irregular heart rhythm, rate may vary, normal P waves, progressive lengthening
of PRI, some P waves not followed by QRS, usually normal QRS
What is the treatment for 2nd degree heart block Mobitz I? - ANSWER✔
Generally no treatment necessary
Treat underlying cause, monitor, possibly pace
What are the s/sx of 2nd degree heart block Mobitz II? - ANSWER✔ Fatigue,
dyspnea, chest pain, presyncope, syncope, sudden cardiac arrest
irregular rhythm, varying rate, normal size and shape of P waves, some P waves
not followed by QRS, normal or prolonged PRI BUT always constant for
conducted beats, usually normal QRS but absent at times, atria/junction is still
telling ventricle what to do
What is the treatment for 2nd degree Mobitz II? - ANSWER✔ O2 if needed,
may need pacing, correct underlying cause
What are the s/sx of 3rd degree heart block (complete)? - ANSWER✔ light-
headedness, dizziness, fainting, fatigue, chest pain, bradycardia
ventricles fire own impulse (wide and wacky), atrial and ventricular rates are
independently regular, atrial rate = 60-100, ventricular rate = 20-40, p waves are
normal but not related to QRS, no PRI due to dissociation, QRS depends on
level of escape rhythm
