NUR 302 - Ch 39: Oxygenation and Perfusion (PrepU - EXAM 2)

The nurse is teaching the client with a pulmonary disorder about deep breathing. The client asks, "Why is it important to start by breathing through my nose, then exhaling through my mouth?" Which appropriate response would the nurse give this client?

"Breathing through your nose first will warm, filter, and humidify the air you are breathing." Explanation: Nasal breathing allows the air to be warmed, filtered, and humidified. Nose breathing does not encourage the client to sit up straight. The purpose of nasal breathing is not to prevent germs from entering the stomach or to discourage snoring.

A client who uses portable home oxygen states, "I still like to smoke cigarettes every now and then." What is the appropriate nursing response?

"You should never smoke when oxygen is in use."

The nurse is caring for a client with emphysema. When teaching the client pursed-lip breathing, the nurse will include which instruction(s)? Select all that apply.

-Inhale slowly through the nose for a count of three. -Shape the lips as if you were about to blow a whistle. -Over time, begin to increase the length of the exhale. -Exhale slowly through pursed lips. -Ensure that the exhale lasts twice as long as the inhale.

Which should the nurse teach the family about caring for a client with emphysema at home? Select all that apply.

-Maintain a smoke-free environment. -Watch for increased wheezing or signs of a flare-up. -Take advantage of pulmonary rehabilitation programs. -Follow health care provider's prescription for oxygen administration -Create a long-term caregiving plan.

The obstetric nurse is assisting the birth of a preterm neonate. In preparing for the respiratory needs of the neonate, the nurse is aware that surfactant is formed in utero around:

34-36 wks Explanation: Surfactant is formed in utero around 34 to 36 weeks. An infant born prior to 34 weeks may not have sufficient surfactant produced, leading to collapse of the alveoli and poor alveolar exchange. Synthetic surfactant can be given to the infant to help reopen the alveoli.

In which client should the nurse prioritize assessments for respiratory depression?

A client taking opioids for cancer pain Explanation: Many medications affect the function of the respiratory system and depress the respiratory system. The nurse should monitor clients taking certain medications, such as opioids, for rate and depth of respirations. Beta-adrenergic blockers, antibiotics, and insulin do not appreciably affect the respiratory system.

Wheezing

Air passing through narrowed airways

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 Explanation: If the client is not breathing with an adequate rate and depth, or if the client has lost the respiratory drive, a manual resuscitation bag (Ambu bag) may be used to deliver oxygen until the client is resuscitated or can be intubated with an endotracheal tube.

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 as prescribed Explanation: The nurse should first apply oxygen, which will help to improve oxygen saturation and health status. The client may not require intubation, once oxygen is provided. Although the client may require education on incentive spirometry, the immediate priority intervention is to stabilize the client's oxygen saturation. Similarly, raising the head of the bed may help with the client's comfort but may not have sufficient effect on oxygen saturation.

The nurse is educating an adolescent with asthma on how to use a metered-dose inhaler. Which instruction will the nurse include in the teaching?

Be sure to shake the canister before using it.

When the nurse observes a newborn infant demonstrating an irregular abdominal breathing pattern, with a respiratory rate of 40 breaths/minute with occasional pauses in breathing of 5-second duration. What is the most appropriate action by the nurse?

Continue to assess the infant.

A nurse using a pulse oximeter to measure a client's SpO2 obtains a reading of 95%. What is the nurse's most appropriate action?

Document this expected assessment finding.

Which dietary guideline would be appropriate for the older adult homebound client with advanced respiratory disease who informs the nurse that she has no energy to eat?

Eat smaller meals that are high in protein.

The nurse assesses a client and detects the following findings: difficulty breathing, increased respiratory and pulse rates, and pale skin with regions of cyanosis. What condition would the nurse suspect as causing these respiratory alterations?

Hypoxia Explanation: Hypoxia is a condition in which an inadequate amount of oxygen is available to cells. Difficulty breathing, increased respiratory and pulse rates, and pale skin with regions of cyanosis are all signs of hypoxia. Hyperventilation is an increased rate and depth of ventilation, above the body's normal metabolic requirements. Perfusion refers to the process by which oxygenated capillary blood passes through body tissues. Atelectasis refers to collapsed alveoli.

pleural rub

Inflammation of pleural surfaces

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.

The nurse is caring for a client who is wearing oxygen via nasal cannula. The client asks about the bubbling water attached to the oxygen. Which response by the nurse is appropriate?

It decreases dry mucous membranes by delivering small water droplets.

Which teaching about the oxygen analyzer is important for the nurse to provide to a client using oxygen?

It determines whether the client is getting enough oxygen.

The nurse is suctioning a client's tracheostomy when the tracheostomy becomes dislodged and the nurse is unable to replace it easily. What is the nurse's most appropriate response?

Maintain the client's oxygenation and alert the health care provider immediately Explanation: If the tracheostomy becomes dislodged and is not easily replaced, the nurse should notify the primary care provider immediately, cover the tracheostomy stoma, and assess client's respiratory status.

bronchovesicular breath sounds

Medium-pitched blowing sounds heard over the major bronchi

Which statement accurately describes a general consideration when performing CPR on a client?

Perform CPR on an obese client the same as on a non-obese client Explanation: Perform CPR in the same manner if the client is obese. If the nurse is unsure whether the client has a pulse, CPR should be initiated anyhow. Hands-only CPR is not recommended for victims of drowning, trauma, airway obstruction, and acute respiratory distress. If available, use a one-way valve mask over a child's nose and mouth when performing CPR.

Which diagnostic procedure measures lung size and airway patency, producing graphic representations of lung volumes and flows?

Pulmonary function tests

A client returns to the telemetry unit after an operative procedure. Which diagnostic test will the nurse perform to monitor the effectiveness of the oxygen therapy ordered for the client?

Pulse Oximetry

A client vomits as a nurse is inserting his oropharyngeal airway. What would be the most appropriate intervention in this situation?

Remove the airway, turn the client to the side, and provide mouth suction, if necessary.

Stridor

Sputum in the airway; a harsh, noisy squeak when something is blocking the airway.

The nurse is performing an arterial blood gas sampling on a client at 10:45. The nurse educator intervenes if which action is taken by the nurse?

The nurse performs the Allen test after blood sample is taken. Explanation: The Allen test is done before puncture to ensure adequate ulnar blood flow when using the radial artery. The arterial specimen is immediately placed on ice and taken to the laboratory. The radial, brachial, or femoral arteries are usually the sites of choice for an arterial blood sampling. The nurse should apply pressure for 5 to 10 minutes, longer if the client is on anticoagulant therapy.

The nurse is auscultating the lungs of a client and detects normal vesicular breath sounds. What is a characteristic of vesicular breath sounds?

They are low-pitched, soft sounds heard over peripheral lung fields.

The nurse is caring for a client who has had a percutaneous tracheostomy (PCT) following a motor vehicle accident and has been prescribed oxygen. What delivery device will the nurse select that is most appropriate for this client?

Tracheostomy collar

After insertion of a chest tube, fluctuations in the water-seal chamber that correspond with inspiration and expiration are an expected and normal finding

True Explanation: fter insertion of a chest tube, fluctuations in the water-seal chamber that correspond with inspiration and expiration are an expected and normal finding. A nurse caring for a client with a chest tube should monitor the client's respiratory status and vital signs, check the dressing, and maintain the patency and integrity of the drainage system.

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

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 client's hands and try again.

The nurse auscultates the lungs of a client with asthma who reports shortness of breath, sore throat, and congestion. Which finding does the nurse expect to document?

Wheezing

A nurse is volunteering at a day camp. A child is stung by a bee and develops wheezing in the upper airways. The child is experiencing:

a bronchospasm. Explanation: When allergic responses take place in the lungs, breathing difficulties are far more severe. Small airways become edematous, mucus production increases, and inflammatory chemical mediators cause bronchospasm.

The nurse is caring for the following clients. Which client is at highest risk for a depressed respiratory system?

a client taking an opioid for cancer pain Explanation: Many medications affect the function of, and depress, the respiratory system. The nurse should monitor clients taking certain medications, such as opioids, for rate and depth of respirations. Amlodipine is a calcium channel blocker and the medication decreases blood pressure, so the nurse would need to assess blood pressure. Muscle relaxants such as methocarbamol could depress respiratory status, but this occurs less often than with opioids. Methimazole is used to treat hyperthyroidism, thus lowering the body's metabolic functions, which can depress respirations; however, this is a very rare occurrence with this medication. The client at highest risk is the one taking an opioid.

bronchial breath sounds

are loud, high-pitched sounds heard over the trachea and larynx.

crackle breath sounds

are soft, high-pitched, discontinuous popping sounds heard on inspiration.

A client has edema of the feet and ankles, along with crackles in the lower lobes and a frothy, productive cough. The client is suffering from:

congestive heart failure.

The nurse auscultates a client with soft, high-pitched popping breath sounds on inspiration. The nurse documents the breath sounds heard as:

crackles

The nurse is implementing an order for oxygen for a client with facial burns. Which delivery device will the nurse gather?

face tent

Course Crackles

heard on auscultation indicate the presence of fluid in the lungs

Croup

is common young children, is a condition that obstructs upper airways by swelling the throat tissues

Total lung capacity

is the amount of air contained within the lungs at maximum inspiration

Forced expiratory volume

measures the amount of air exhaled in the first second after a full inspiration; it can also be measured at 2 or 3 seconds.

vesicular breath sounds

normal and described as low-pitched, soft sounds over the lungs' peripheral fields

A client's primary care provider has informed the nurse that the client will require thoracentesis. The nurse should suspect that the client has developed which disorder of lung function?

pleural effusion Explanation: Thoracentesis involves the removal of fluid from the pleural space, either for diagnostic purposes or to remove an accumulation of fluid in this space (pleural effusion). Tachypnea and wheezes are not symptoms that directly indicate a need for thoracentesis. Pneumonia would necessitate the procedure only if the infection resulted in pleural effusion.

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

While auscultating a client's chest, the nurse auscultates crackles in the lower lung bases. What condition does the nurse identify the client is experiencing?

presence of fluid in the lungs

Tidal volume

refers to the total amount of air inhaled and exhaled with one breath

The nurse is caring for a client with a chest tube. Which assessment finding indicates that the tube is functioning correctly?

respirations are at 20 breaths per minute

The air quality index has rated it a red air quality day in the city. Which information will the nurse share with the client about promoting effective respiratory self-care?

stay indoors as much as possible

Pneumonia

which causes the lungs to swell and stiffen, can lead to atelectasis. Stiffer lungs tend to collapse, and their alveoli also collapse. Consequently, the amount of space available for gas exchange in the lungs decreases

Asthma

Causes the small airways to become inflamed and narrowed. Alcohol use depresses the central respiratory center.

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?

Flow meter

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 (RV)

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.

The nurse is caring for a postoperative client who has a prescription for meperidine 75 mg intramuscularly (IM) every 4 hours as needed for pain. Before and after administering meperidine, the nurse would assess which most important sign?

respiratory rate and depth
