A nurse is suctioning a clients tracheostomy using an open
system. Which of the following actions should the nurse
take?
a. Use clean technique to perform the procedure
b. Apply suction when inserting the catheter
c. Administer 100% oxygen before the procedure
d. Suction the tracheostomy for 20 seconds each time
c. Administer 100% oxygen before the procedure
-An open system requires sterile technique, while a closed
requires clean
-The nurse should apply intermittent suction to reduce risk for
hypoxia and administer 100% o2
-The nurse should apply suction for 10 to 15 seconds to reduce
risk for hypoxia.
A nurse is discussing ventilation and perfusion with a
newly licensed nurse. The nurse should include in the
discussion that the exchange of oxygen and carbon dioxide
occurs at which of the following locations?
1
,a. trachea
b. alveoli
c. diaphragm
d. bronchial tubes
b. alveoli
-trachea allows air to move in and out of the lungs during
ventilation
-diaphragm contracts and relaxes to facilitate ventilation
-the bronchial tubes allow air to move in and out of the lungs
A nurse is reviewing the medical history of a client who
has heart disease and a narrow valve. Which of the
following findings should the nurse expect?
a. regurgitation
b. stenosis
c. muscle atrophy
d. hypotension
b. stenosis
-stenosis is a narrowed valve
-regurgitation is a leaky valve
-stenosis will cause hypertrophy not muscle atrophy
-stenosis causes hypertension
A nurse is planning to measure the cardiac output of a
client who had a myocardial infarction. Which of the
2
,following data should the nurse use to calculate the clients
cardiac output?
a. respiratory rate
b. blood pressure
c. stroke volume
d. vital capacity
c. stroke volume
-CO= SV X HR
A nurse is assessing a client who is receiving oxygen
therapy. The nurse should identify that which of the
following findings can indicate oxygen toxicity?
a. hypertension
b. ringing in the ears
c. fever
d. dilated pupils
b. ringing in the ears
-oxygen toxicity can cause hyperventilation and dyspnea,
shivering (not fever), blurred/doubled vision, ringing in the
ears, headache, disorientation, muscle twitching
A nurse is obtaining a health history from a client. Which
of the following findings should the nurse identify as risk
factors for heart disease?
a. a diet high in saturated fats
3
, b. a history of an overactive bladder
c. a history of smoking for 25 years
d. a sedentary lifestyle
e. a waist circumference of 84 cm (33 in)
A,C,D
-Overactive bladder does not contribute to heart disease
-waist cm of 102 (women) or 89 (men) increases risk for
heart disease.
