Question

5. An infant patient presents with stridor and profound inhalation.  He has signs of a viral infection (e.g. fever and general malaise). What upper respiratory obstructive disorder is most likely occurring in this patient?

1. A patient presents with signs of combative behavior, hypotension and bradycardia.  You suspect he has a disorder of ventilation.  

A) What would you detect is aberrant in terms of blood gas concentration if he has hypoxemia?

B) What would you detect is aberrant in terms of blood gas concentration if he has hypercapnia?

2. A patient presents with a stab wound to the chest.  You are listening to his heart and establish that during exhalation his heart moves very close to the anatomical midline but during inhalation his heart moves away from the midline.  In addition, you observe that no air is escaping from the stab wound.  Based upon this information, what type of pleural disorder does this patient have?

3. A) What is pleural effusion?  

B) What is a medical consequence of this condition?

4. Based upon your knowledge of how aspirin blocks the effects of inflammatory mediators produced from arichidonic acid, provide a rationale how aspirin could trigger or exacerbate asthma.

5. What would you predict most likely happens in terms of heart function or status if a patient has very severe chronic obstructive pulmonary disorder?

Answer 1

5. The infant is most likely to have "respiratory syncytical virus".

1.A

In hypoxemia, the oxygen partial pressure in the blood go below normal.

1.B

In hypercapnia, the blood contain heavy level of carbon dioxide.

2.

The patient is suffering from pleural effusion.

3.A

Pleural effusion is an abnormal condition where there cells of lungs are filled with fluids due to poor pumping of the heart.

B.

The consequences of pleural effusion is that the person have difficulty in breathing while walking or while sitting and if not treated could lead to the death of the person.

4. Aspirin block the effects of inflammatory mediators produced by blocking the normal post-glandin function which is responsible for causing inflammation.

5. The heart attack is most likely to be happen if a patient have severe chronic obstructive inflammatory disease.
