a) fremitus
b) hyperventilation
c) pleural friction rub
d) hypoventilation
d) hypoventilation.
When auscultating Mr. Chang’s breath sounds, the nurse detects a continuous, musical sound heard on expiration. The nurse identifies this sound as which of the following?
a) crackles
b) wheezes
c) bronchial sounds
d) pleural friction rub
b) wheezes
Air that develops in the pleural space is referred to as:
a) pneumothorax
b) pleural effusion
c) hemothorax
d) atelecatasis
a) pneumothorax
When planning care for a patient with a chronic lung disease who is receiving oxygen through nasal canula, what dos the nurse expect?
a) The oxygen must be humidified.
b) The rate will be 2 L/min or less.
c) Arterial blood gases will be drawn every 4 hours to assess flow rate.
d) The rate will be 6 L/min or more.
b) The rate will be 2 L/min or less.
Which oxygen delivery device would the nurse expect to use to provide the highest concentration of oxygen to a patient who is breathing spontaneously?
a) Partial rebreather mask
b) Nonrebreather mask
c) Simple mask
d) Venturi mask
b) Nonrebreather mask
When teaching a patient about pulse oximetry, which statement would the nurse most likely include in the discussion?
a) A range of 95% to 100% is considered normal oxygen saturation.
b) Oximetry measures the oxygen saturation of the venous blood.
c) Fasting is required for 12 hours before the test.
d) Pulse oximetry is a replacement for arterial blood gas analysis.
a) A range of 95% to 100% is considered normal oxygen saturation.
Which action would the nurse include when performing oropharyngeal suctioning on a patient?
a) Use clean technique.
b) Apply suction as the catheter is introduced.
c) Flush the catheter with saline between catheter insertions.
d) Limit suctioning to 25- to 30-second intervals at one time.
c) Flush the catheter with saline between catheter insertions.
Effective use of a metered-dose inhaler requires that the patient accomplish which action?
a) Breathe in through the nose.
b) Inhale two sprays with one breath.
c) Hold the breath for 5 to 10 seconds after inspiration.
d) Exhale quickly through an open mouth.
c) Hold the breath for 5 to 10 seconds after inspiration.
Mr. Parks has COPD. The nurse has taught him that pursed-lip breathing helps him by:
a) Increasing carbon dioxide, which stimulates breathing.
b) Prolonging inspiration and shortening expirations.
c) Liquefying his secretions.
d) Decreasing the amount of air trapping and resistance.
d) Decreasing the amount of air trapping and resistance.
A patient develops sudden cardiac arrest. It is imperative to begin CPR as soon as possible. What is the critical time that the nurse must keep in mind before irreversible brain damage occurs?
a) 1 to 3 minutes.
b) 2 to 4 minutes.
c) 4 to 6 minutes.
d) 8 to 10 minutes.
c) 4 to 6 minutes.
David White is in the hospital with a medical diagnosis of viral pneumonia. He is receiving oxygen through a simple face mask. The nurse ensures that the mask fits snugly over the patient’s face for which reason?
a) To prevent mask movement and consequent skin breakdown.
b) To help the patient feel secure.
c) To maintain carbon dioxide retention.
d) To aid in maintaining expected oxygen delivery.
d) To aid in maintaining expected oxygen delivery.
When suctioning a patient through a tracheostomy tube, the nurse was careful not to occlude the Y port when inserting the suction catheter because this could do which of the following?
a) Prevent suctioning from occurring
b) Cause trauma to the tracheal mucosa
c) Break the sterile technique
d) Suction out all the carbon dioxide
b) Cause trauma to the tracheal mucosa.
What action does the nurse use to follow safe technique when using a portable oxygen cylinder?
a) Checking the amount of oxygen in the cylinder before using it.
b) Using a cylinder for a patient transfer that indicates available oxygen is 500 psi.
c) Placing the oxygen cylinder on the stretcher next to the patient.
d) Discontinuing oxygen flow and turning the cylinder key counterclockwise until tight
a) Checking the amount of oxygen in the cylinder before using it.
Which of the following assessments should the nurse consider when performing tracheal suctioning? Select all that apply.
a) Close assessment of the patient before, during, and after the procedure.
b) Hyperoxygenate the patient before and after suctioning.
c) Limit the application of suction to 20 to 30 seconds.
d) Monitor the patient’s pulse frequently to detect potential effects of hypoxia and stimulation of the vagus nerve.
e) Using an appropriate suction pressure (80 to 100 mm Hg).
f) Insert the suction catheter as far as it will go before applying suction. This will help prevent atelectasis r/t the use of high negative pressure.
a,b,d,e
Abdominal breathing at 30 to 60 breaths/minute with an irregular pattern of rate and depth would closely describe the breathing of what age group?
a) Aged adult
b) Infant
c) Early Childhood
d) Late Childhood
b) Infant
