Grade: A+|Status: Guaranteed Pass
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 - Answers -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. - Answers -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 - Answers -A. Alveolar hypoventilation
2|Page
,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 - Answers -C. Cromolyn sodium
Cromolyn is given by inhalation and prevents the degranulation of the mast cells with release of
histamine. Cromolyn is a prophylactic agent. It has no effect in an acute asthmatic attack.
Which of the following would not be used for hypertensive crisis in the presence of acute heart
failure?
A.
3|Page
, Hydralazine
B.
Nitroglycerin
C.
Nitroprusside
D.
Esmolol - Answers -D. Esmolol
"Hydralazine," "Nitroglycerin," and "Nitroprusside" are vasodilators, whereas esmolol is a β-
blocker. Choose "Esmolol."
Esmolol is a β-blocker and would decrease contractility and so would be contraindicated in
acute heart failure.
A 24-year-old man has been diagnosed with acute kidney injury as a result of severe
hemorrhaging after a motor vehicle collision. Which of the following would be expected
laboratory values for this patient?
A.
Low urinary osmolality, high urinary sodium concentration
B.
High urinary osmolality, high urinary sodium concentration
C.
Low urinary osmolality, low urinary sodium concentration
D.
