A nurse is caring for client who is experiencing supraventricular tachycardia. Upon
assessing the client, the nurse observes the following findings: heart rate 200/min,
blood pressure 78/40 mm Hg, and respiratory rate 30/min. Which of the following
actions should then nurse take?
a. Defibrillate the client's heart.
b. Perform synchronized cardioversion.
c. Begin cardiopulmonary resuscitation.
d. Administer lidocaine IV bolus. -correct answerb. Perform synchronized
cardioversion.
The nurse should perform synchronized cardioversion for a client who has
supraventricular tachycardia.
What rhythms are shockable? (defibrillation) -correct answerventricular fibrillation and
pulseless ventricular tachycarida
What dysrhythmia are amiodarone and lidocaine indicated for? -correct
answerventricular arrhythmias
,The nurse should initiate CPR for a client who what? -correct answeris pulseless or not
breathing
A nurse is preparing a client who has supraventricular tachycardia for elective
cardioversion. Which of the following medications should the nurse instruct the client to
withhold for 48 hr prior to cardioversion?
A. Enoxaparin
B. Metformin
C. Diazepam
D. Digoxin -correct answerD. digoxin
Cardiac glycosides, such as digoxin, are withheld prior to cardioversion. These
medications can increase ventricular irritability and put the client at risk for ventricular
fibrillation after the synchronized countershock of cardioversion
_______ are usually given prior to cardioversion to reduce anxiety and minimize
discomfort with the procedure. -correct answerSedatives like diazepam
Metformin is held before what kind of procedures? Example? Why? -correct
answerOnes that involve contrast dye like cardiac catheterization, in order to prevent
kidney damage.
__________ prevent blood clots that can be released into the circulatory system after
cardioversion. -correct answerAnticoagulants like enoxaparin
What kind of drugs are withheld prior to cardioversion? -correct answercardiac
glycosides like digoxin
exopthalmosis -correct answercondition produced by hyperthyroidism in which the
eyeballs protrude beyond their normal protective orbit because of swelling in the tissues
behind them
entropion -correct answerthe inversion of the edge of an eyelid
ectropion -correct answerthe eversion of the edge of an eyelid
ptosis -correct answerdrooping
A nurse is caring for a client who has emphysema and is receiving mechanical
ventilation. The client appears anxious and restless, and the high-pressure alarm is
sounding. Which of the following actions should the nurse take first?
A. Obtain ABGs.
B. Administer propofol to the client.
C. Instruct the client to allow the machine to breathe for them.
D. Disconnect the machine and manually ventilate the client. -correct answerC.
Instruct the client to allow the machine to breathe for them. When providing client care,
, the nurse should first use the least restrictive intervention. Therefore, the first action the
nurse should take is to provide verbal instructions and emotional support to help the
client relax and allow the ventilator to work. Clients can exhibit anxiety and restlessness
when trying to "fight the ventilator."
A nurse is caring for a client who has a potassium level of 3. Which of the following
assessment findings should the nurse expect?
A. Positive Trousseau's sign
B. 4+ deep tendon reflexes
C. Deep respirations
D. Hypoactive bowel sounds -correct answerD. Hypoactive bowel sounds
Deep tendon reflexes are used to monitor what electrolyte level? -correct
answermagnesium
What kind of respirations occur with hypokalemia and why? -correct answershallow
respirations due to respiratory muscle weakness
Trosseau's sign evaluates for what electrolyte imbalances? -correct
answerhypocalcelmia and hypomagnesemia
What is hypokalemia's effect on the GI system? -correct answerIt decreases smooth
muscle contraction leading to decreased peristalsis and hypoactive bowel sounds.
Deep tendon reflexes in hypomagnesemia -correct answerincreased e.g. 4+
Deep tendon reflexes in hypermagnesemia -correct answerdecreased e.g. absent or
1+
What should be done if you are performing a cardiac assessment on a client and you
hear a murmur? -correct answerListen with the client on their left side so it can be
heard more clearly
A nurse is conducting an admission history for a client who is to undergo a CT scan with
an IV contrast agent. The nurse should identify that which of the following findings
requires further assessment?
A. History of asthma
B. Appendectomy 1 year ago
C. Penicillin allergy
D. Total knee arthroplasty 6 months ago -correct answerA. History of asthma
A client who has a history of asthma has a greater risk of reacting to the contrast dye
used during the procedure. Other conditions that can result in a reaction to contrast
media include allergies to foods, such as shellfish, eggs, milk, and chocolate.
