What is the proper way to assess respiratory status?

Have patient sit up. Inspection: normally the thorax is symmetrical and the anterior posterior diameter is less than the transverse diameter, respirations should be even, unlabored, at a rate of 12 to 20 bpm, inspiration is normally half as long as expiration and chest expansion should be symmetrical. If patient appears anxious, has nasal flaring, cyanosis of the lips/mouth, intercostal retractions, or use of accessory muscles he/she may be in respiratory distress. Start on back check for symmetric lung expansion by noting that thumbs move apart symmetrically, feel for fremitis (say 99 to generate vibrations, examine for crepitus (a course crackling sensation when palpating skin), measure diaphragmatic excursion (distance between marks to determine-normally 5-6 cm in adults). Auscultate his lung sounds starting at C7 down to T10, percuss anterior and lateral chest (dullness over diaphragm, liver, or other organs is normal, but over lungs may indicate a mass or consolidation.

What should you do if your patient's C02 is less than 35?

They need more C02 so breath into bag and suck in more C02 (NO O2).

What should you do if your patient's C02 is greater than 45?

Need less C02 so have them cough out or slow/deep breathing (pursed lip breathing).

What is the most common type of acid base imbalance?

Respiratory acidosis

Who is respiratory acidosis common in?

COPD, PNEUMONIA, BED REST, AND MEDICATED PATIENTS.

What is the relationship between acidosis and CO2?

Acidosis means you are retaining too much C02!

Who is respiratory alkalosis common in?

Panic attack and pant breathing used in labor.

What is the relationship between alkalosis and CO2?

Too much C02 is being blown off.

How should you correctly apply a pulse oximeter to a patient?

Choose an application site (finger, toe, nose, forehead, or ear) with adequate circulation, remove polish or artificial fingernails, make sure the high and low SPO2 and pulse alarms are set appropriately (NEVER DISARM AN ALARM), DON'T APPLY PULSE OX SENSOR TO AN EXTREMITY WITH AN AUTOMATIC BLOOD PRESSURE CUFF, AND DON'T APPLY TO THE INDEX FINGER ON THE PATIENTS DOMINANT HAND.

Where should you apply a pulse ox sensor for a COPD patient?

On an earlobe because they have sausage fingers and their reading won't be accurate.

What is thoracentesis?

A sterile procedure performed by a Dr. where a needle is inserted to remove excess fluid from the pleural space.

What is the nurses responsibility for assisting with thoracentesis?

Help position the patient, support them, and assess for complications. Make sure informed consent, assess for allergies, perform baseline assessment, MUST STAY STILL DURING PROCEDURE (PNEUMOTHORAX= POSSIBLE)- FEET SHOULD BE PLANTED ON THE GROUND, monitor VS and S&S of pneumothorax (dyspnea, tachycardia, chest pain).

What is capnography?

A noninvasive technique to alert you to hypoventilation even when your patient's pulse ox reading are fine. Carbon dioxide is the most significant factor in monitoring ventilation. Capnography measures the CO2 in every breath to monitor air exchange in the patient's alveoli.

What should you do if your patients capnograph wave shows apnea (one wave then nothing)?

Shake the patient and hope come back to normal.

What should you do if your patients capnograph wave shows shallow hypoventilation (shallow/low waves)?

If they have a pillow under there neck and their chin is to their chest it means their airway is closed off so need to REMOVE PILLOW.

When should the capnograph waveforms be displayed?

With each exhaled breath

Is a patient who pulls out their endotracheal tube with a balloon attached a priority patient?

No because they will breath just fine (28 days can stay in).

Can an NA feed a pt post laryngectomy?

Yes! Air from the nose and mouth doesn't go to lungs anymore because not connected. There is no risk for aspiration so an NA can feed them. Breathing will occur through stoma in neck.

Wait 15 seconds between suctioning and don't suction for more than 10 seconds/pass.

What is important to remember with a cuff trach?

5 cc of air should be put into it to inflate cuff before eat or drink anything. Also, if the trach is capped bc not in use YOU MUST MAKE SURE THE CUFF IS DEFLATED OTHERWISE THEY ARE ONLY BREATHING THROUGH THE TRACH (AND ITS CAPPED!).

What type of trach is used in pediatrics?

Protects the trachea upon insertion.

What should be done if you are trying to suction someone but the trach is occluded and won't facilitate suctioning?

Pull inner cannula out and clean.

Is suctioning in home care sterile? Hospital?

Suctioning in home care is clean. In the hospital it's sterile.

HYPEROXYGENATE BEFORE AND AFTER SUCTIONING, STABILIZE NECK FLANGES AND REMOVE INNER CANNULA, CLEAN WITH EQUAL PARTS H202 AND NACL WEARING STERILE GLOVES, REINSERT AND SECURELY LOCK, SECURE NEW TIES TO TRACHEOSTOMY BEFORE REMOVING OLD ONES (BC IF COUGH OUT NEW TRACH WILL CLOSE).

What should not be done during tracheostomy care?

DONT CUT GAUZE AND PLACE UNDER THE TRACH TUBE FLANGES BC FIBERS/STRING CAN BE INHALED INTO THE TRACH.

IS AN AUDIBLE CROWING PATIENT A PRIORITY PATIENT?

YES

What is the only way to get a sterile sputum sample from a trach?

You need a line connecter with a T attachment to connect the suction catheter to a collection container. The secretions must be wet for testing!

What should be taught to a pt about cancer of the larynx? (select all that apply)

It can be caused by smoking, tx is removal of the larynx and permanent stoma placement, you are at risk of lung pollutants (avoid baby powder or aerosol sprays), artificial saliva may be needed, NO SWIMMING, Have carbon monoxide/smoke detectors, gulping air while eating=modified valsalva, talking while burping= esophageal speech.

If a person post laryngectomy sucks up a bug where does it go?

LUNG

What is a lung, bone, or ventilation perfusion scan? Teaching?

The pt is injected with radioisotope and placed under a scanner (any type of scan). The patient must void before the test and lie still during.

What should be taught to a patient about strep throat? (select all that apply)

It is a beta strep organism, it is contagious so the pt needs to be in a private room with droplet precautions, S&S include fever, chills, and sore throat, bright red/white pustules may be present, increased in WBC is expected, culture 1st then antibiotics given q6 hrs around the clock, and complications w/o tx include rheumatic/scarlet fever, mitral valve disease (vegitation/growth), or glomerulonephritis (peds).

For how long is a trach considered new?

7 days

What occurs in the event of inadvertent tracheal decannulation? What should you do?

Most likely the stoma will close and the patient will become tachypneic, signs of respiratory distress will arise, and oxygen sat will fall. You should call the emergency response team to attempt and reinsert (nurses don't reinsert trachs), use a bag-valve mask device to ventilate (ventilate gently) and place the pt in semi fowlers.
