DETAILED ANSWERS
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.
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 CVP (Central venous pressure) in adults - ANSWER-2-8 mmHg
Normal cardiac output in adults - ANSWER-4-8 L/min
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. 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
C. Increased vasodilation and enhanced myocardial contractility
D. Bronchoconstriction and increased heart rate - ANSWER-B (Bronchodilation results from stimulated
beta receptors, and cardiac effects result from the stimulation of ß1 receptors. Choice A does not
address respiratory effects of medication. Choice C is incorrect because α-stimulating drugs cause
vasoconstriction. Bronchodilation, not bronchoconstriction, results from ß2 activity.)
Following norepinephrine (Levophed) administration, it is essential to the nurse to assess:
A. electrolyte status
B. color and temperature of toes and fingers
C. capillary refill
D. ventricular arrhythmias - ANSWER-B (Because decreased perfusion is a side effect of norepinephrine
(Levophed), the nurse must check circulation frequently. Capillary refill is not a reliable indication of
perfusion in a shock state. Choices A and D are not specific for norepinephrine.)
When administering dopamine (Intropin), it is most important for the nurse to know that:
A. the drug's action varies according to the dose.
B. the drug may be used instead of fluid replacement.
C. the drug cannot be directly mixed in solutions containing bicarbonate or aminophylline.
D. the lowest dose to produce the desired effect should be used. - ANSWER-C (The nurse is responsible
for knowing compatible solutions before administering dopamine (Intropin). It is important to know that
drug action varies by dose, but the physician is responsible for determining the dose. Dopamine should
, not be used instead of fluid replacement. Choice D is incorrect because, although it is true, it is not the
nurse's primary concern. It is a collaborative action in which the physician is involved in determining the
rate.)
Dobutamine (Dobutrex) improves cardiac output and is indicated for use in all of the following conditions
except:
A. septic shock
B. congestive heart failure
C. arrhythmias
D. pulmonary congestion - ANSWER-C (Dobutamine (Dobutrex) is not used to treat arrhythmias. Choices
A, B, and D are conditions are conditions that respond to dobutamine.)
Which of the following effects of calcium channel blockers causes a reduction in blood pressure?
A. Increased cardiac output
B. Decreased peripheral vascular resistance
C. Decreased renal blood flow
D. Calcium influx into cardiac muscles - ANSWER-B
A preoperative patient receives atropine before induction of anesthesia. The nurse caring for this patient
understands that this agent is used to prevent:
A. anxiety.
B. bradycardia.
C. dry mouth.
D. hypertension. - ANSWER-B (Atropine, an anticholinergic drug, is used as an adjunct to anesthesia to
counter the effects of vagal stimulation, which is caused by surgical manipulations that trigger
parasympathetic reflexes, resulting in bradycardia. Atropine is not an anxiolytic. Atropine causes dry
mouth and sometimes is used to minimize bronchial secretions.)
When titrating an analgesic to manage pain, what is the priority goal?
A. Administer smallest dose that provides relief with the fewest side effects.
B. Titrate upward until the client is pain free.
