QUESTION: The nurse is preparing to administer lisinopril (Zestril) to a patient with acute
coronary syndrome. Which of the following findings should prompt the nurse to hold the
medication and consult the healthcare provider?
a) Serum sodium level 134
b) Serum potassium 5.6
c) Heart rate 58
d) Blood pressure 125/78 - ANSWER-b) Serum potassium 5.6
*ACE inhibitors can cause/exacerbate hyperkalemia.
QUESTION: The nurse is caring for a patient who is in hypovolemic shock following an
extensive burn injury. What is the intravenous fluid of choice for this patient in the emergent
phase of treatment?
a) Lactated Ringers
b) 0.45 NS with 20 mEq potassium chloride
c) Fresh Frozen Plasma
d) 5% Dextrose in saline - ANSWER-a) Lactated Ringers
*Isotonic solutions (crystalloids) are used to restore fluid volume in patients with shock.
Lactated Ringers is isotonic. Normal saline is also isotonic.
QUESTION: The client on a ventilator is assessed for untoward responses to the therapy.
Which of the following would indicate a possible complication of ventilator therapy?
a) Blood pressure has increased 5mmHg in the last 24 hours
b) Lung sounds absent on one side.
c) Forceful cough periodically
, 4 |Page
d) Broncho-vesicular breath sounds throughout peripheral lung fields. - ANSWER-b) Lung
sounds absent on one side.
*This may indicate a pneumothorax--a complication caused by barotrauma.
QUESTION: The pressure reading during inspiration on the ventilator of a client receiving
mechanical ventilation is high and alarming intermittently. What is the nurse's first action?
a) Assess the client's oxygenation.
b) Call the RT to check the ventilator settings.
c) Listen for bilateral lung sounds.
d) Determine whether an air leak is present in the client's endotracheal tube cuff. - ANSWER-a)
Assess the client's oxygenation.
QUESTION: Which assessment finding best indicates that fluid resuscitation therapy for the
patient with hypertonic dehydration has acheived the desired effect?
a) Peripheral pulses changed from 1+ to 3+
b) Neck veins slightly distended @ 30 degrees
c) Serum sodium level has changed from 151 to 143.
d) Pulse oximetry shows oxygen saturation of 95% - ANSWER-c) Serum sodium level has
changed from 151 to 143.
QUESTION: Which intravenous solution should you be prepared to administer to a patient with
isotonic dehydration?
a) 0.45% saline
b) Dextrose 5% in water
c) Dextrose 10% in water
d) 0.9% saline - ANSWER-d) 0.9% saline
