You are caring for a patient who is experiencing delirium due to a lack of sl
n n n n n n n n n n n n n n n
eep. Which of the following nursing interventions would be
n n n n n n n n
*inappropriate* in treating this patients' condition? n n n n n
a. You treat the patients' primary diagnosis that is causing the delirium.
n n n n n n n n n n
b. You turn on the lights and a radio next to the patients' bed to reorient the
n n n n n n n n n n n n n n n
m.
c. You use appropriate touch and verbal communication to help reorient th
n n n n n n n n n n
e patient.

d. You put an easy-to- n n n
read clock in the patients' room and a calendar close to their bed. -
n n n n n n n n n n n n n
nCORRECT ANSWER B (For treating delirium, the nurse should reduce
n n n n n n n n n n
environmental stimuli by decreasing noise and light levels.)n n n n n n n
,Normal Potassium level - CORRECT ANSWER 3.5-5.0
n n n n n n
Normal PR interval length - CORRECT ANSWER <0.2 seconds
n n n n n n n n
Normal QRS interval length - CORRECT ANSWER <0.12 seconds
n n n n n n n n
Normal CVP (Central venous pressure) in adults -
n n n n n n n
CORRECT ANSWER 2-8 mmHg
n n n n
Normal cardiac output in adults - CORRECT ANSWER 4-8 L/min
n n n n n n n n n
Normal cardiac index in adults - CORRECT ANSWER 2.2-

Normal MAP in adults - CORRECT ANSWER 70-105 mmHg

The action of medication is inotropic when it:
n n n n n n n
A. Decreased afterload n
B. Increases heart rate n n
C. Increases the force of contraction n n n n
D. Is used to treat CHF -
n n n n n
CORRECT ANSWER C (Inotropic drugs increase the force of contr
n n n n n n n n n n
action. Preload, not afterload, is decreased. Chronotropic drugs increas
n n n n n n n n
e heart rate. Treatment of CHF is an indication for use not an action of i
n n n n n n n n n n n n n n n
notropic drug.) n
,Which of the following ECG findings alerts the nurse that the client needs
n n n n n n n n n n n n n
an antiarrhythmic?
n
A. Normal sinus rhythm n n
B. Sinus bradycardia n
C. Sinus arrhythmia n
D. Frequent ventricular ectopy - n n n
nCORRECT ANSWER D (Ventricular ectopy can be a life-n n n n n n n n
threatening arrhythmia; therefore, the client needs an arrhythmic. Other ch
n n n n n n n n n
oices are not arrhythmias that need to be treated. An ectopic rhythm is an ir
n n n n n n n n n n n n n n
regular heart rhythm due to a premature heartbeat. Ectopic rhythm is also
n n n n n n n n n n n n
known as premature atrial contraction, premature ventricular contraction,
n n n n n n n n
and extrasystole. When your heart experiences an early beat, a brief pause
n n n n n n n n n n n n
usually follows.) n
When administering an antiarrhythmic agent, which of the following asses
n n n n n n n n n
sment parameters is the most important for the nurse to evaluate?
n n n n n n n n n n
A. ECG
B. Pulse rate n
C. Respiratory rate n
D. Blood pressure - n n
nCORRECT ANSWER A (The ECG is the most important parameter to a
n n n n n n n n n n n
ssess. B, C, and D need to be monitored, but the ECG is the most important.

Epinephrine is used to treat cardiac arrest and status asthmaticus because of
n n n n n n n n n n n
which of the following actions?
n n n n n
A. Increased speed of conduction and gluconeogenesisn n n n n
, B. Bronchodilation and increased heart rate, contractility, and c n n n n n n n
onduction
C. Increased vasodilation and enhanced myocardial contractility
n n n n n
D. Bronchoconstriction and increased heart rate - n n n n n
nCORRECT ANSWER B (Bronchodilation results from stimulated beta
n n n n n n n n
receptors, and cardiac effects result from the stimulation of ß1 receptors. C
n n n n n n n n n n n
hoice A does not address respiratory effects of medication. Choice C is inc
n n n n n n n n n n n n
orrect because α-
n n
stimulating drugs cause vasoconstriction. Bronchodilation, not bronchoc
n n n n n n
onstriction, results from ß2 activity.) n n n n
Following norepinephrine (Levophed) administration, it is essential to the
n n n n n n n n n
nurse to assess:
n n
A. electrolyte status n
B. color and temperature of toes and fingers
n n n n n n
C. capillary refill n
D. ventricular arrhythmias - n n
nCORRECT ANSWER B (Because decreased perfusion is a side effect of
n n n n n n n n n n
nnorepinephrine (Levophed), the nurse must check circulation frequently.
n n n n n n n n
Capillary refill is not a reliable indication of perfusion in a shock state. Cho
n n n n n n n n n n n n n
ices A and D are not specific for norepinephrine.)
n n n n n n n n
When administering dopamine (Intropin), it is most important for the nurse
n n n n n n n n n n n
to know that:
n n
A. the drug's action varies according to the dose.
n n n n n n n
B. the drug may be used instead of fluid replacement.
