Critical care 1

Question 1

Where would you NOT expect to find a critically ill patient?

(a) recovery room
(b) ICU
(c) step-down or intermediate unit
(d) medical ward

Answer 1

(d) medical ward - this is less severe

Question 2

where would you be surprised to see an arterial line?

(a) carotid artery
(b) radial artery
(c) femoral artery
(d) dorsalis pedis artery

Answer 2

(a) carotid artery - too crazy

Question 3

What is the minimum MAP needed to get blood into the brain, heart vessels, and kidneys?

(a) 45 mm Hg
(b) 50 mm Hg
(c) 60 mm Hg
(d) 70 mm Hg

Answer 3

(c) 60 mm Hg - remember MAP is (systolic + 2diastolic)/3, so for example ideally it is (120 + 80 + 80)/3 = 93.33333…. normal range is 70-110.

Question 4

The loss of a central venous line is a medical emergency T/F

Answer 4

False, it’s the arterial line falling out that’s a medical emergency

Question 5

where would you be surprised to see a central venous line?

(a) femoral vein
(b) subclavian vein
(c) jugular vein
(d) vein in the upper arm

Answer 5

(d) vein in the upper arm - this is for a peripherally inserted venous IV catheter (meds > monitoring though) which is an alternative to a central line which doesn’t need changing as often.

Question 6

Blood products can be delivered through a

(a) arterial line
(b) central venous line
(c) peripherally inserted central IV catheter
(d) peripheral intravenous line

Answer 6

(b) central venous line - this is the only one that mentions blood products in the slides

Question 7

IV lines can deliver total parental nutrition T/F

Answer 7

False - they can deliver basic but not total, that can be done through a CVL.

Question 8

CVP can appear abnormally high with all EXCEPT

(a) overhydration
(b) PEEP
(c) increased pulmonary vascular resistance
(d) pulmonary hypotension

Answer 8

(d) pulmonary hypotension - it’s pulmonary hypertension that would back pressure up into the superior vena cava

Question 9

Which of the following statements is FALSE?

(a) The swan ganz catheter can be inserted at the antecubital vein.
(b) A high PAP can be due to left ventricular insufficiency.
(c) The PAWP is a reflection of the end-systolic L ventricular pressure.
(d) PAWP is normally between 5-12 mm Hg.

Answer 9

(c) The PAWP is actually a reflection of end-diastolic L ventricular pressure.

Question 10

PAWP greater than ____ can result in interstitial edema?

(a) 5
(b) 12
(c) 18
(d) 30

Answer 10

(c) 18 - normal is 5-12, 12-18 is optimal, 18-30 is interstitial, 30+ is pulmonary edema

Question 11

Naso-gastric tubes can be used for both feeding and suctioning T/F

Answer 11

True

Question 12

When might nasal prongs not be the greatest choice for supplemental O2?

(a) patient is a mouth breather
(b) you need an FiO2 of 45%
(c) patient has a deviated septum
(d) all of the above

Answer 12

(d) all of the above

Question 13

you want a mask that can deliver over 60% FiO2. You choose a:

(a) simple face mask
(b) partial rebreathing mask
(c) non-rebreathing mask
(d) venturi mask

Answer 13

(c) non-rebreathing mask
