PATHO 370 TEST 4 EXAM QUESTIONS WITH COMPLETESOLUTIONS 2022 UPDATE
D. D. is a 66 year-old female suffering from shortness of breath. She smoked 2 packs a day until
she quit 2 years ago. She has a history of bronchiolitis, hyperinflated lungs, pulmonary edema,
and syncope. Her primary care practitioner suspects she also has pulmonary hypertension (PH).
After examination, D. D. has a PAP of 35mmHg and mild CHF.
Citing scholarly resources, answer the following questions:
1. What is pulmonary hypertension and how could D. D. have developed PH?
In healthy lungs, there is a low arterial resistance and venous resistance, so that
contributes to the fact that the left side of the heart is much stronger. Pulmonary
Hypertension is caused by an increase in blood pressure in the pulmonary arteries to the
lungs. The heart is working much harder than it should to get the blood to the lungs. D.D.
most likely developed this issue because of her consistent smoking habit.
2. How does her history fit in with her new diagnosis?
Her history of smoking has lent a heavy hand in all of her prior illnesses. For example,
the chemicals inhaled by smoking has damaged the membranous layer of her layer,
which is how fluid is entering her lungs, causing pulmonary edema. All of these illnesses
combined are making it harder for her heart and lungs to do their job properly which is
why she now has pulmonary hypertension.
3. What are the three types of bronchodilators, and how do they function to alleviate the
symptoms of COPD? What are other possible treatments for COPD?
The three types are Beta-adrenergic agonists, anticholinergics, and methylxanthines. The
Beta-agonists bind to receptors in the lung and block the trigger to the spasms, allowing
the airways to remain open. They can be taken orally or via MDI. Anticholinergics
block acetylcholine production, which in turn stop the spasms. These are inhaled. The
last type, methylxanthines, are the last resort type of drug. They also alleviate airflow
obstruction. Corticosteriods, antibiotics, and even opioids can also be used to treat
COPD.
