A patient hospitalized with chronic obstructive pulmonary disease (COPD) is being discharged home on oxygen therapy. Which instruction should the nurse include in the discharge teaching?

A.

Store the oxygen tanks near sources of heat to prevent them from freezing.

B.

Use the oxygen therapy only during periods of activity or exertion.

C.

Adjust the oxygen flow rate to the highest level possible to improve breathing.

D.

Use the oxygen therapy continuously, even during sleep.

Answer and Explanation

The Correct Answer is D

A. Storing oxygen tanks near sources of heat is dangerous. Oxygen should be stored in a cool, dry place away from heat sources and flammable materials to prevent the risk of fire or explosion.  

B. Oxygen therapy should not be limited to periods of activity or exertion. For patients with COPD, continuous oxygen therapy is often necessary to maintain adequate oxygen saturation levels, even during sleep.  

C. Adjusting the oxygen flow rate to the highest level can be harmful, especially in patients with COPD, as it may suppress their hypoxic drive to breathe. The flow rate should be prescribed and adjusted by the healthcare provider.  

D. Continuous use of oxygen therapy, even during sleep, is essential for maintaining adequate oxygen saturation levels in patients with COPD. This helps prevent hypoxemia and ensures the patient receives the necessary oxygen support.

Correct Answer is ["0.5"]

Explanation

Convert units: Since the available medication is in mg, convert the prescribed dose from mcg to mg. There are 1000 mcg in 1 mg, so:

125 mcg / 1000 mcg/mg = 0.125 mg

· Set up the calculation: Divide the desired dose by the available dose per tablet:

0.125 mg / 0.25 mg/tablet = X tablets

· Solve for X:

X = 0.5 tablets

Correct Answer is ["A","C","D"]

Explanation

A. Decreased PaO2 <60mmHg: A hallmark of fat embolism syndrome (FES) is hypoxemia, which results in a PaO2 less than 60 mmHg. This is a key indicator of the severity of respiratory compromise in FES and ARDS.

B. PaO2 greater than 80mmHg: This would not be consistent with FES. Fat embolism often causes significant hypoxemia, and PaO2 greater than 80 mmHg would indicate adequate oxygenation.

C. Decreased platelet count and hematocrit levels: In fat embolism syndrome, there is often a decrease in platelet count and hematocrit due to disseminated intravascular coagulation (DIC), which can occur as a complication of fat embolism.

D. Changes in ST segment and T-wave: Electrocardiographic changes, including changes in ST segment and T-wave, are commonly seen in fat embolism syndrome due to myocardial injury, hypoxemia, or shock.

E. PaCO2 40mmHg: A PaCO2 of 40 mmHg is within normal limits and does not indicate any significant respiratory distress or abnormality that would be expected in fat embolism syndrome.
