1 Your patient may be at risk for sepsis if they have a suspected infection and a temperature greater than

98.6° F
99.0° F
100.0° F
100.4° F

The following scenario will be used for Questions 2-5: You are called code 3 for a 24 year old male who presented to urgent care after submersion for 1 minute in a frozen lake. The patient was still in their wet clothes when they arrived at urgent care and has since been stripped, dried, and surrounded by warmed blankets and placed on an automated monitor with the pulse oximetry on their left ring finger and blood pressure cuff on the right arm. The patient's core temperature is 96.9° F as of 2 minutes ago per staff. Other vital signs are respiratory rate of 10 deep and unlabored, SPO2 not reading on room air, blood pressure 142/66, pulse 58 bpm strong and regular, pupils 4 mm PERRL, blood glucose unable to be obtained, skin signs are cool and dry. The patient is conscious, alert and oriented x4, complaining of right knee pain from when they fell through the ice.

2 Is this patient's temperature outside of the normal boundaries for adult?


3 Does this patient require oxygen therapy?

Yes, their SPO2 is too low to be read.
Yes, hypothermia requires oxygen therapy.
No, because they are breathing at a normal rate.
There is not enough evidence in the question to determine whether oxygen therapy is warranted or not.

4 Given this patient's presentation, what would you expect their capillary refill to be?

0.5-1 second
1-1.5 seconds
1.5-2 seconds
> 2 seconds

5 This patient's core temperature is likely higher than the temperature at the extremities.


6 You respond for an interfacility transport of a patient who reported experiencing shortness of breath following exercise. Their SPO2 is 94% on room air. Is this within normal bounds?


7 A patient exhibits peri-oral cyanosis and tachypnea. They are most likely


8 Which of the following would potentially inhibit correct assessment via pulse oximeter?

Nail Polish
Cold Fingers
Poor Circulation
Carbon Monoxide poisoning
Darkly pigmented skin
None of the above

9 Excessive sweating is known as


10 Cyanosis is

A bluish hue to the skin that indicates hypovolemia
A bluish hue to the skin that indicates hypoxia
A greenish hue to the skin that indicates hypovolemia
A greenish hue to the skin that indicates hypoxia
