A nurse is instructing the client on the normal sensations that can occur when contrast medium is infused during pulmonary angiography. Which client statement demonstrates an understanding of the teaching?
"I will feel warm and may have chest pain" Explanation: During a pulmonary angiography, a contrast medium is injected into the femoral circulation. When the medium is infused, the client will feel warm and flushed, with a possibility of chest pain. The client will feel pressure when the catheter is inserted. The client does not typically feel light-headed or nauseated during this procedure.
The nurse assessed a 28-year-old woman who was experiencing dyspnea severe enough to make her seek medical attention. The history revealed no prior cardiac problems and the presence of symptoms for 6 months' duration. On assessment, the nurse noted the presence of both inspiratory and expiratory wheezing. Based on this data, which of the following diagnoses is likely?
Asthma Explanation: The presence of both inspiratory and expiratory wheezing usually signifies asthma if the individual does not have heart failure. Sudden dyspnea is an indicator of the other choices.
What is the purpose of the vascular and ciliated mucous lining of the nasal cavities?
Correct response: 463 and humidify inspired air Explanation: The vascular and ciliated mucous lining of the nasal cavities warms and humidifies inspired air. It is the function of the cilia alone to move mucus in the nasal cavities and filter the inspired air.
The nurse enters the room of a client who is being monitored with pulse oximetry. Which of the following factors may alter the oximetry results? 1 Increased temperature of the room 2 Placement of the probe on an earlobe 3 Diagnosis of peripheral vascular disease 4 Reduced lighting in the room
Diagnosis of peripheral vascular disease Pulse oximetry is a noninvasive method of monitoring oxygen saturation of hemoglobin. A probe is placed on the fingertip, forehead, earlobe, or bridge of nose. Inaccuracy of results may be from anemia, bright lights, shivering, nail polish, or peripheral vascular disease.
A nurse is concerned that a client may develop postoperative atelectasis. Which nursing diagnosis would be most appropriate if this complication occurs? Ineffective airway clearance Impaired spontaneous ventilation Impaired gas exchange Decreased cardiac output
Impaired gas exchange Explanation: Airflow is decreased with atelectasis, which is a bronchial obstruction from collapsed lung tissue. If there is an obstruction, there is limited or no gas exchange in this area. Impaired gas exchange is thus the most likely nursing diagnosis with atelectasis.
A nurse practitioner diagnosed a patient with an infection in the maxillary sinuses. Select the area that the nurse palpated to make that diagnosis. Above the eyebrows Behind the ethmoid sinuses On the cheeks below the eyes Between the eyes and behind the nose
On the cheeks below the eyes Explanation: To palpate the maxillary sinuses, the nurse should apply gentle pressure in the cheek area below the eyes, adjacent to the nose.
The client has just had an invasive procedure to assess the respiratory system. What does the nurse know should be assessed on this client? Masses in pleural space Loss of consciousness Respiratory distress Watery sputum
Respiratory distress After invasive procedures, the nurse must carefully check for signs of respiratory distress and blood-streaked sputum. Masses in the pleural space are a condition that affects fremitus. General examination of overall health and condition includes assessing the consciousness of a client.
Which of the following ventilation-perfusion mismatch would correlate with acute respiratory distress syndrome (ARDS)?
Silent unit Explanation: A silent unit (a combination of shunting and dead-space ventilation) occurs when little or no ventilation and perfusion is present, such as in ARDS. A dead space, which is reduced perfusion to a lung unit, occurs in pulmonary embolism. Shunting, reduced ventilation to a lung unit, occurs in pneumonia and atelectasis. Patients with ARDS do not have a normal V/Q [adV]/[adQ]) match.
A client experiences a head injury in a motor vehicle accident. The client's level of consciousness is declining, and respirations have become slow and shallow. When monitoring a client's respiratory status, which area of the brain would the nurse realize is responsible for the rate and depth? 1 Central sulcus 2 Wernicke's area 3 The frontal lobe 4 The pons
The pons The inspiratory and expiratory centers in the medulla oblongata and pons control the rate and depth of ventilation. When injury occurs or increased intracranial pressure results, respirations are slowed. The frontal lobe completes executive functions and cognition. The central sulcus is a fold in the cerebral cortex called the central fissure. The Wernicke's area is the area linked to speech.
The term for the volume of air inhaled and exhaled with each breath is ? tidal volume. vital capacity. expiratory reserve volume. residual volume.
Tidal volume is the volume of air inhaled and exhaled with each breath. Residual volume is the volume of air remaining in the lungs after a maximum expiration. Vital capacity is the maximum volume of air exhaled from the point of maximum inspiration. Expiratory reserve volume is the maximum volume of air that can be exhaled after a normal inhalation.
