Which patient is most at risk for developing delirium?
a. A 50-yr-old woman with cholecystitis
b. A 19-yr-old man with a fractured femur
c. A 42-yr-old woman having an elective hysterectomy
d. A 78-yr-old man admitted to the medical unit with
complications related to heart failure - .....ANSWER
...✔✔ D
You are caring for a patient who is experiencing
delirium due to a lack of sleep. Which of the following
nursing interventions would be *inappropriate* in
treating this patients' condition?
a. You treat the patients' primary diagnosis that is
causing the delirium.
,2|Page
b. You turn on the lights and a radio next to the patients'
bed to reorient them.
c. You use appropriate touch and verbal communication
to help reorient the patient.
d. You put an easy-to-read clock in the patients' room
and a calendar close to their bed. - .....ANSWER
...✔✔ B (For treating delirium, the nurse should
reduce environmental stimuli by decreasing noise and
light levels.)
Normal Potassium level - .....ANSWER ...✔✔ 3.5-5.0
Normal PR interval length - .....ANSWER ...✔✔ <0.2
seconds
Normal QRS interval length - .....ANSWER ...✔✔
<0.12 seconds
Normal CVP (Central venous pressure) in adults -
.....ANSWER ...✔✔ 2-8 mmHg
Normal cardiac output in adults - .....ANSWER ...✔✔
4-8 L/min
,3|Page
Normal cardiac index in adults - .....ANSWER ...✔✔
2.2-4 L/min/m squared
Normal MAP in adults - .....ANSWER ...✔✔ 70-105
mmHg
The action of medication is inotropic when it:
A. Decreased afterload
B. Increases heart rate
C. Increases the force of contraction
D. Is used to treat CHF - .....ANSWER ...✔✔ C
(Inotropic drugs increase the force of contraction.
Preload, not afterload, is decreased. Chronotropic drugs
increase heart rate. Treatment of CHF is an indication
for use not an action of inotropic drug.)
Which of the following ECG findings alerts the nurse that
the client needs an antiarrhythmic?
A. Normal sinus rhythm
B. Sinus bradycardia
C. Sinus arrhythmia
D. Frequent ventricular ectopy - .....ANSWER ...✔✔ D
(Ventricular ectopy can be a life-threatening
arrhythmia; therefore, the client needs an arrhythmic.
, 4|Page
Other choices are not arrhythmias that need to be
treated. An ectopic rhythm is an irregular heart rhythm
due to a premature heartbeat. Ectopic rhythm is also
known as premature atrial contraction, premature
ventricular contraction, and extrasystole. When your
heart experiences an early beat, a brief pause usually
follows.)
When administering an antiarrhythmic agent, which of
the following assessment parameters is the most
important for the nurse to evaluate?
A. ECG
B. Pulse rate
C. Respiratory rate
D. Blood pressure - .....ANSWER ...✔✔ A (The ECG is
the most important parameter to assess. 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 which of the following actions?
A. Increased speed of conduction and gluconeogenesis
B. Bronchodilation and increased heart rate, contractility,
and conduction
