Question 1 of 10

1. Question
Regarding the treatment of frostbite, which of the following statements are correct?

Select one or more options.
- Tissue should be slowly rewarmed in water circulating at 37°C
- Active gentle motion of the part by the patient during rewarming should be encouraged, but direct tissue massage should be avoided
- Tissue pressures should be monitored carefully, although decompressing escharotomies are usually not necessary during the initial treatment
- In the presence of haemorrhagic blisters, surgical debridement should be considered early on in management
Question 2 of 10

2. Question
Which of the following are risk factors for the development of hypothermia?

Select one or more options.
- Burns, because of decreased heat conservation
- Diabetes
- Acute spinal cord transaction, because of impaired thermoregulation
- Extreme exertion, because of decreased heat production/thermogenesis
- Anorexia nervosa
Question 3 of 10

3. Question
Which of the following are clinical manifestations of hypothermia?

Select one or more options.
- Initial decrease in cardiovascular system activity, followed by an increase
- Initial decrease in respiratory rate, followed by an increase
- Impaired judgement and memory followed by slurred speech
- Increased renal activity resulting in a diuresis
- Coagulopathy in patient with normal PT/APTT
Question 4 of 10

4. Question
The ECG findings of a hypothermic patient can include which of the following?

Select one or more options.
- Prolongation of the R-R interval
- Tall, tented T-waves
- A prolonged P-R interval
- Sinus bradycardia in mild hypothermia
- Osborn J waves in the precordial leads
Question 5 of 10

5. Question
Regarding the management of hypothermia, which of the following statements are correct?

Select one or more options.
- The patient should be encouraged to exercise to generate heat
- The hypothermic patient should be handled with care, as their myocardium is prone to developing ventricular fibrillation (VF)
- The bradycardic, hypothermic patient should be given atropine to treat their arrhythmia
- Dextrose-saline fluid challenges should be given to the hypothermic patient because they are dehydrated and volume-depleted
Question 6 of 10

6. Question
With regard to the re-warming strategies employed, which of the following statements are correct?

Select one or more options.
- Active, external rewarming is the method of choice in mild-to-moderate hypothermic patients
- Passive rewarming should be reserved for the patient with mild hypothermia who is still able to generate heat by shivering
- The Bair-Hugger system is an example of active, core rewarming
- Rhabdomyolysis with electrolyte abnormalities is an indication for active, core rewarming
- Cardiopulmonary bypass is an example of extracorporeal blood rewarming
Question 7 of 10

7. Question
With regard to the pathophysiology of hypothermia, which of the following statements are correct?

Select one or more options.
- Heat is generated by cellular metabolism at a rate of 40-60 kcal of heat per square metre of body surface area (BSA)
- Shivering can generate up to 300 kcal of heat per square metre of BSA
- Physiological responses are as effective as behavioural responses to heat conservation
Question 8 of 10

8. Question
Which of the following groups are at high risk for frostbite?

Select one or more options.
- The very young and the very old
- Adults aged 30-49 years old
- Afro-Caribbean and Arabic people
- Patients who consume alcohol
Question 9 of 10

9. Question
Regarding the clinical appearance of frostbite, which of the following statements are correct?

Select one or more options.
- Superficial frostbite is characterised by clear blisters
- Deep frostbite affects the bones and tendons
- Haemorrhagic blisters are seen in superficial frostbite
- Hard eschar formation is seen in superficial frostbite
- Deep frostbite only affects and skin and superficial tissue
Question 10 of 10

10. Question
Which of the following are favourable prognostic indicators of frostbite?

Select one or more options.
- Intact sensation to pinprick
- Dark, haemorrhagic blisters
- Skin that still deforms under pressure
- Hard, non-deforming skin
- Loss of skin sensation
