Critical Care Final Exam Questions and
Correct Detailed Answers Already Graded A+
Hypothermia - CORRECT ANSWER-Trauma from freezing temperature and
actual freezing of fluid in the intracellular and intercellular spaces
Manifestations: hard, cold, and insensitive to touch, may appear white or
mottled, may turn red and painful as rewarmed
Controlled but rapid rewarming; 37° to 40°C circulating bath for 30- to 40-minute
intervals. DO NOT LET TEMP GO BELOW 32.2 C.
Analgesics for pain
Do not massage or handle; if feet are involved, do not walk
Esophageal foley - CORRECT ANSWER-What is the most reliable way to check
body temp?
ROSC - CORRECT ANSWER-Return of Spontaneous Circulation- when pulses
return to a patient who has been in cardiac arrest
It slows down metabolic rate - CORRECT ANSWER-Why would you go into
ROSC protocol for a patient who has hypothermia?
,MAP-ICP - CORRECT ANSWER-How do you find the CPP?
systolic + 2(diastolic)/3 - CORRECT ANSWER-How do you find the MAP?
PR Interval - CORRECT ANSWER-0.16- 0.21.
The line from the beginning of the P wave to the beginning of the QRS complex.
4ml/2ml x TBSA x Kg
CONVERT TO LITERS - CORRECT ANSWER-What is the math formula for a
patient with burns?
Rule of 9's - CORRECT ANSWER-Each arm= 9%, Anterior leg=9%, Posterior
leg=9% Head=9%, Back=18% Chest=18%, Perineum=1%
4ml - CORRECT ANSWER-How many ml of fluid would you give an electrical
burn patient?
2ml - CORRECT ANSWER-How many ml of fluid would you give a
thermal/chemical burn patient?
,divide it in half - CORRECT ANSWER-If fluid is ordered on a burn patient for 8
hours, what do you do with the total amount of fluid?
Superficial, deep partial, full thickness - CORRECT ANSWER-What are the types
of burns?
1st degree burn - CORRECT ANSWER-Sunburn, scaled/steam/hot pan (short
period of time)
S/S: Red, itchy, swollen, blisters, dry, non blanchable
Tx: oral pain meds, cool compress, skin lubricant, medihoney
2nd degree burn - CORRECT ANSWER-Superficial partial thickness-
scalds/flame/contact (for increased period of time)
S/S: blisters, red, mottling, weeping, edema, pain, hyperesthesia, sensitive to air
Tx: Recovery- 2 weeks, scarring, wet to dry dressings, skin grafting, escharotomy,
pain medication, medihoney, silver sulfamide
3rd Degree burn - CORRECT ANSWER-Full thickness- epidermis, dermis, and
sub Q tissue
Chemical, electrical, long exposure to flame, gasoline
, S/S: Charred, leathery, entry and exit wound (electrical), dry, pale, edema, eschar,
slough, grafting, scarring, loss of function
Watch for dysrthymias. Have on heart monitor and have defibrillator ready -
CORRECT ANSWER-What are nursing interventions when a patient has an
electrical burn?
ineffective Airway, impaired gas exchange, risk for infection, inadequate nutrition
- CORRECT ANSWER-What are nursing diagnosis for a burn patient?
Assess: Resp distress, airway, circulation, electrolytes/dehydration, urine output,
vitals, past history
S/S: increased RR, changes in BP, elevated HR, stridor, wheezing, bloody sputum,
horseness, soot around nose and mouth
Tx: Check airway, IV fluids (LR&NS), oxygen, check potassium, pain management,
glucose checks, nutrition support (avoid TPN and Lipids), antibiotics - CORRECT
ANSWER-How is a patient with thermal burns monitored and treated?
Caused by bleach, acid, paint thinner, lye, white phosphorus and mustard powder
Same s/s and treatment as thermal.
Wipe powder off
