face tent

An older adult client is visibly pale with a respiratory rate of 30 breaths per minute. Upon questioning, the client states to the nurse, "I can't seem to catch my breath." The nurse has responded by repositioning the client and measuring the client's oxygen saturation using pulse oximetry, yielding a reading of 90%. The nurse should interpret this oxygen saturation reading in light of the client's:

hemoglobin level

high fowlers position

pulmonary function tests

The nurse is performing a check with an oxygen analyzer. Which oxygen analyzer assessment finding indicates that the device is working properly?

reads 0.21 when checking oxygen in room air

The nurse schedules a pulmonary function test to measure the amount of air left in a client's lungs at maximal expiration. What test does the nurse order?

residual volume

When caring for a client with a tracheostomy, the nurse would perform which recommended action?

suction the trachestomy tube using sterile technique

The nurse is caring for a client who has a compromised cardiopulmonary system and needs to assess the client's tissue oxygenation. The nurse would use which appropriate method to assess this client's oxygenation?

arterial blood gas

When a nurse observes that an older client's skin is dry and shiny and his nails are thickened, the nurse determines that the client is most likely experiencing

poor tissue perfusion

A nurse takes a client's pulse oximetry reading and finds that it is normal. What does this finding indicate?

the client's available hemoglobin is adequately saturated with oxygen.

A nurse assessing a client's respiratory status gets a weak signal from the pulse oximeter. The client's other vital signs are within reference ranges. What is the nurse's best action?

warm the clients hands and try again

During data collection, the nurse auscultates low-pitched, soft sounds over the lungs' peripheral fields. Which appropriate terminology would the nurse use to describe these lung sounds when documenting?

vesicular

The nurse is informed while receiving a nursing report that the client has been hypoxic during the evening shift. Which assessment finding is consistent with hypoxia?

Confusion

A health care provider orders the collection of a sputum specimen from a client with a suspected bacterial infection. Which action best ensures a usable specimen?

Instruct the client to inhale deeply and then cough

A nurse is caring for an asthmatic client who requires a low concentration of oxygen. Which delivery device should the nurse use in order to administer oxygen to the client?

Nasal Cannula

A client is admitted to the hospital with shortness of breath, cyanosis and an oxygen saturation of 82% (0.82) on room air. Which action should the nurse implement first?

apply oxygen

A nurse is reading a journal article about pollutants and their effect on an individual's respiratory function. Which problem would the nurse most likely identify as an effect of exposure to automobile pollutants?

bronchitis

While examining a client, the nurse palpates the client's chest and back. What would the nurse expect to identify with this technique?

pattern of thoracic expansion

A nurse is assigned to care for a client admitted to the health care facility with the diagnosis of atelectasis. When interviewing the client, the nurse would anticipate a history of

pneumonia

A nurse suctioning a client through a tracheostomy tube should be careful not to occlude the Y-port when inserting the suction catheter because it would cause what condition to occur?

trauma to the tracheal mucosa

The nurse performs assessments of cardiopulmonary functioning and oxygenation during regular physical assessments. Based on developmental variations, which findings would the nurse consider normal? Select all that apply.

-The power of the respiratory and abdominal muscles is reduced in older adults, and therefore the diaphragm moves less efficiently. -The normal infant's chest is small and the airways are short, making aspiration a potential problem. -Alterations in respiratory function due to aging in older adults increase the risk for disease, especially pneumonia and other chest infections. -The respiratory rate is more rapid in infants until the alveoli increase in number and size to produce adequate oxygenation at lower respiratory rates.

The nurse educator is presenting a lecture on the respiratory and cardiovascular systems. Which response given by the nursing staff would indicate to the educator that they have an understanding of cardiac output?

"if the client's stroke volume is 50mL and heart rate is 50 beats per minute, then the cardiac output is 2.5L/minute."

A client is reporting slight shortness of breath and lung auscultation reveals the presence of bilateral coarse crackles. The client's SaO2 is 90% on pulse oximetry. The nurse has applied supplementary oxygen by nasal cannula, recognizing that the flow rate by this method should not exceed:

6 L/minute

When inspecting a client's chest to assess respiratory status, the nurse should be aware of which normal finding?

The chest should be slightly convex with no sternal depression.

Which guideline is recommended for determining suction catheter depth when suctioning an endotracheal tube?

Using a suction catheter with centimeter increments on it, insert the suction catheter into the endotracheal tube until the centimeter markings on both the endotracheal tube and catheter align, and insert the suction catheter no further than an additional 1 cm.

A nurse assessing a client's respiratory effort notes that the client's breaths are shallow and 8 per minute. Shortly after, the client's respirations cease. Which form of oxygen delivery should the nurse use for this client?

ambu bag

Which medication is administered in the home or the hospital to relieve inflammation in the lung tissue?

document this assessment finding

A client has been put on oxygen therapy because of low oxygen saturation levels in the blood. What should the nurse use to regulate the amount of oxygen delivered to the client?
