, 1. When teaching a family member to perform an aspect of patient care, the
nurse should understand that family members
Correct Answer: learn best if they perceive a need to learn.
Family members learn best if they perceive a need to learn. This is consistent
with adult learning theory. Establishing a "need to know" is an important first
step for optimal educational efforts. The timing of education is important for an
optimal outcome to be realized. Teaching unrelated tasks will not enhance
learning and is a waste of the family's and provider's time. Learners are
goaloriented and want to make a connection between what they are being
taught and the goal (skill or knowledge) needed to solve a problem. If they
recognize the relevance of the task, they are more likely to be successful.
2.Which hemodynamic profile is MOST consistent with distributive shock?
Correct Answer: BP 84/42, CVP 3, PAOP 8, Cl 2.5, SVR 475, Sv02
52%
In distributive shock types (e.g., anaphylactic or neurogenic), there is a
decrease in venous return, which causes a low CVP. Loss of vessel tone results
in a decreased SVR. A higher CVP indicates a high preload. The Sv02 will be
lower in shock states.
3. A patient with head trauma is experiencing increased intracranial
pressure. The ideal level at which to maintain
the arterial pc02 is between Correct Answer:
35 and 45.
Normocapnia is essential for maintaining stable intracranial pressure, because
CO2 directly affects the degree of vasodilation in cerebral blood vessels.
Hyperventilation decreases arterial CO2 tension, which can result in cerebral
vasoconstriction and decreased cerebral blood flow. A pCO2 between 45 and
50 will not help the patient's clinical situation. An elevated CO2 level will cause
vasodilation, which will increase cerebral blood flow and, subsequently,
intracranial pressure.
4. The major effect of ARDS on lung tissue isCorrect Answer: decreased
compliance.
Decreased compliance is related to alteration of lung endothelium and vascular
tissue. Pathophysiologic changes in lung vascular tissue and increased lung
edema contribute to the decrease in compliance. The end result is stiffness of
the fluid-filled nonaerated airways. There is an increase in capillary
