A 25-year-old man admitted with multiple trauma has had significant changes in the last
12 hours. His temperature is 39° C, his skin is warm and dry, and he is restless and
agitated. The following are his hemodynamic parameters:
Blood pressure88/48 mm Hg
Heart rate124 beats/min
Cardiac output10.5 L/min
Cardiac index5.25 L/min/m2
Right atrial pressure4 mm Hg
Pulmonary artery occlusive pressure3 mm Hg
Systemic vascular resistance (SVR)452 dynes/sec/cm-5
Venous oxygen saturation90%
Vasopressors might be required in this patient to do which of the following?
A.
Maintain renal blood flow.
B.
,Increase coronary blood flow.
C.
Increase venous return and preload.
D.
Restore vascular tone and afterload. - ANSWER- D
RATIONALE: The massive vasodilation caused by mediators in response to
infection primarily decreases vascular tone and afterload. Vasopressors aid in the
restoration of the vascular tone
*A 42-year-old woman is admitted with a diagnosis of acute pancreatitis as a result of
cholelithiasis. She is complaining of severe abdominal pain and states that she has
been vomiting for 2 days. Some of her emesis appears like coffee grounds. Her blood
pressure is 80/40 mm Hg, and her heart rate is 130 beats/min. Which of the following
lab values would be expected in this patient?
A.
Increased albumin
B.
Increased calcium
C.
Increased potassium
D.
Increased lipase - ANSWER- D
,RATIONALE: Lipase and amylase are elevated in pancreatitis. Alkaline
phosphatase and bilirubin would be elevated because of the biliary disease. Potassium
would be decreased because of vomiting. Albumin is decreased because of increased
capillary permeability and protein leakage. Calcium is decreased because of fat
necrosis and precipitation of calcium salts.
Which of the following is the best position for a dyspneic patient?
A.
Prone
B.
Low Fowler
C.
High Fowler
D.
Supine - ANSWER- B
RATIONALE: The best position for a dyspneic patient is low (20-30 degrees) Fowler
position. High Fowler position increases the pressure of the abdominal contents against
the diaphragm, which decreases diaphragmatic excursion.
*A 52-year-old woman developed an epidural hematoma after being in a motor vehicle
collision. She has had a craniotomy to evacuate the clot, and an intraventricular
catheter was placed during surgery. While the nurse is monitoring the patient's
, intracranial pressure (ICP), the pressure climbs to 40 mm Hg but returns to 15 mm Hg
almost immediately. This describes which of the following?
A.
Normal ICP
B.
C wave
C.
B wave
D.
A wave - ANSWER- C
RATIONALE: Normal ICP has a pressure of 5 to 15 mm Hg. An elevation of ICP to
20 to 50 mm Hg occurring every 30 seconds to 2 min is a B wave. An elevation of ICP
to 50 to 100 mm Hg lasting longer than 2 min is an A wave. An elevation of ICP to 20 to
25 mm Hg every 4 to 8 min is a C wave.
*A 54-year-old man had surgery 3 days ago for repair of an abdominal aortic aneurysm.
Acute kidney injury has developed. Lab values reveal the following:
Na 140 mEq/L
K 4.5 mEq/L
Cl 100 mEq/L
HCO3 24 mEq/L
The anion gap would be:
