GRADED A+
A 65-year-old man is admitted to the critical care unit
with a diagnosis of septic shock. He has been receiving
chemotherapy for lung cancer. His skin is warm and dry,
and he is restless. His white blood cell count is elevated
above normal. Hemoglobin, hematocrit, and red blood cell
count are normal.
Vital signs are blood pressure 80/50 mm Hg, heart rate 120
beats/min and regular, respiratory rate 32 breaths/min and
regular, and temperature 39° C.
Arterial blood gases reveal the following:
pH7.25PaO260 mm HgPaCO225 mm HgHCO313
mEq/LOxygen saturation86%
,What hemodynamic alteration should the nurse
anticipate?
A.
Decreased cardiac output (CO)
B.
Increased venous oxygen saturation (SvO2)
C.
Increased systemic vascular resistance (SVR)
D.
Increased oxygen consumption - ....ANSWER...B.
Increased venous oxygen saturation (SvO2)
Early septic shock is different from most forms of shock
because the main problem is oxygen extraction rather
than oxygen delivery. So think opposite of hypovolemic
shock. CO is increased instead of decreased. SVR is
decreased instead of increased. And the SvO2 is increased
instead of decreased.
The primary result of carbon monoxide poisoning is:
,A.
hypoxia.
B.
hypercapnia.
C.
hypertension.
D.
metabolic acidosis. - ....ANSWER...A. hypoxia
A patient with myasthenia gravis develops hypoxemia
with hypercapnia. What is the cause of hypoxemia in this
patient?
A.
Alveolar hypoventilation
B.
Alveolar hyperventilation
C.
Diffusion defect
, D.
Shunt - ....ANSWER...A. Alveolar hypoventilation
Alveolar hypoventilation causes hypoxemia and
hypercapnia. Alveolar hyperventilation would cause
hypocapnia. Diffusion defect or shunt would cause
hypoxemia with normal or decreased PaCO2, depending
on ventilation.
Which of the following drugs stabilizes epithelial mast
cells, thereby reducing the release of histamine?
A.
Triamcinolone
B.
Ipratropium bromide
C.
Cromolyn sodium
D.
Metaproterenol - ....ANSWER...C. Cromolyn sodium
