    A male adult client is suspected of having a pulmonary embolus. A nurse assesses the client. knowing that which of the following is a common clinical manifestation of pulmonary embolism?

    • Dyspnea

    • Bradypnea

    • Bradycardia

    • Decreased respirations

    Correct Answer
    A. Dyspnea
    Explanation

    A nurse is suctioning fluids from a male client via a tracheostomy tube. When suctioning. the nurse must limit the suctioning time to a maximum of:

    • 1 minute

    • 5 seconds

    • 10 seconds

    • 30 seconds

    Correct Answer
    A. 10 seconds
    Explanation
    Hypoxemia can be caused by prolonged suctioning. which stimulates the pacemaker cells in the heart. A vasovagal response may occur. causing bradycardia. The nurse must preoxygenate the client before suctioning and limit the suctioning pass to 10 seconds.

    Nurse Joy is caring for a client after a bronchoscopy and biopsy. Which of the following signs. if noticed in the client. should be reported immediately to the physician?

    • Dry cough

    • Hematuria

    • Bronchospasm

    • Blood-streaked sputum

    Correct Answer
    A. Bronchospasm
    Explanation
    If a biopsy was performed during a bronchoscopy. blood-streaked sputum is expected for several hours. Frank blood indicates hemorrhage. A dry cough may be expected. The client should be assessed for signs of complications. which would include cyanosis. dyspnea. stridor. bronchospasm. hemoptysis. hypotension. tachycardia. and dysrhythmias. Hematuria is unrelated to this procedure.

    Which phrase is used to describe the volume of air inspired and expired with a normal breath?

    • Total lung capacity

    • Forced vital capacity

    • Tidal volume

    • Residual volume

    Correct Answer
    A. Tidal volume
    Explanation
    Tidal volume refers to the volume of air inspired and expired with a normal breath. Total lung capacity is the maximal amount of air the lungs and respiratory passages can hold after a forced inspiration. Forced vital capacity is the vital capacity performed with a maximally forced expiration. Residual volume is the maximal amount of air left in the lung after a maximal expiration.

    A nurse is preparing to obtain a sputum specimen from a male client. Which of the following nursing actions will facilitate obtaining the specimen?

    • Limiting fluid

    • Having the client take deep breaths

    • Asking the client to spit into the collection container

    • Asking the client to obtain the specimen after eating

    Correct Answer
    A. Having the client take deep breaths
    Explanation
    To obtain a sputum specimen. the client should rinse the mouth to reduce contamination. breathe deeply. and then cough into a sputum specimen container. The client should be encouraged to cough and not spit so as to obtain sputum. Sputum can be thinned by fluids or by a respiratory treatment such as inhalation of nebulized saline or water. The optimal time to obtain a specimen is on arising in the morning.

    A male client abruptly sits up in bed. reports having difficulty breathing and has an arterial oxygen saturation of 88%. Which mode of oxygen delivery would most likely reverse the manifestations?

    • Simple mask

    • Non-rebreather mask

    • Face tent

    • Nasal cannula

    Correct Answer
    A. Non-rebreather mask
    Explanation
    A non-rebreather mask can deliver levels of the fraction of inspired oxygen (FIO2) as high as 100%. Other modes — simple mask. face tent. and nasal cannula — deliver lower levels of FIO2.

    The nurse is teaching a male client with chronic bronchitis about breathing exercises. Which of the following should the nurse include in the teaching?

    • Make inhalation longer than exhalation.

    • Exhale through an open mouth.

    • Use diaphragmatic breathing.

    • Use chest breathing.

    Correct Answer
    A. Use diaphragmatic breathing.
    Explanation
    In chronic bronchitis the diaphragm is flat and weak. Diaphragmatic breathing helps to strengthen the diaphragm and maximizes ventilation. Exhalation should be longer than inhalation to prevent collapse of the bronchioles. The client with chronic bronchitis should exhale through pursed lips to prolong exhalation. keep the bronchioles from collapsing. and prevent air trapping. Diaphragmatic breathing — not chest breathing — increases lung expansion.

    A male client who weighs 175 lb (79.4 kg) is receiving aminophylline (Aminophyllin) (400 mg in 500 ml) at 50 ml/hour. The theophylline level is reported as 6 mcg/ml. The nurse calls the physician who instructs the nurse to change the dosage to 0.45 mg/kg/hour. The nurse should:

    • Question the order because it’s too low.

    • Question the order because it’s too high.

    • Set the pump at 45 ml/hour.

    • Stop the infusion and have the laboratory repeat the theophylline measurement.

    Correct Answer
    A. Question the order because it’s too low.
    Explanation
    A therapeutic theophylline level is 10 to 20 mcg/ml. The client is currently receiving 0.5 mg/kg/hour of aminophylline. Because the client’s theophylline level is sub-therapeutic. reducing the dose (which is what the physician’s order would do) would be inappropriate. Therefore. the nurse should question the order.

    A slightly obese female client with a history of allergy-induced asthma. hypertension. and mitral valve prolapse is admitted to an acute care facility for elective surgery. The nurse obtains a complete history and performs a thorough physical examination. paying special attention to the cardiovascular and respiratory systems. When percussing the client’s chest wall. the nurse expects to elicit:

    • Resonant sounds.

    • Hyperresonant sounds.

    • Dull sounds.

    • Flat sounds.

    Correct Answer
    A. Resonant sounds.
    Explanation
    When percussing the chest wall. the nurse expects to elicit resonant sounds — low-pitched. hollow sounds heard over normal lung tissue. Hyperresonant sounds indicate increased air in the lungs or pleural space; they’re louder and lower pitched than resonant sounds. Although hyperresonant sounds occur in such disorders as emphysema and pneumothorax. they may be normal in children and very thin adults. Dull sounds. normally heard only over the liver and heart. may occur over dense lung tissue. such as from consolidation or a tumor. Dull sounds are thudlike and of medium pitch. Flat sounds. soft and high-pitched. are heard over airless tissue and can be replicated by percussing the thigh or a bony structure.
