Mrs. Harriet is a 68 year old woman who is alert and oriented. She presents to the emergency department with complaints of chest tightness, shortness of breath, cougn and congestion. She states, “I have been having these symptoms for three days now. I have been taking Maximum Strength Robitussin for my cough but is has not helped very much. When I woke up this morning, I felt very weak so I came in to be checked out.” Her vital signs are blood pressure 110/70, pulse 94, respiratory rate of 28 and a temperature of 102.7 °F. Her oxygen saturation on room air if 92%. He is placed on 2 liters of oxygen by nasal cannula. The physician prescribes a 12 lead electrocardiogram and chest x-ray. Laboratory test prescribed include CBC, BMP, BNP, CPK, CPK-MB, and troponin. The physician will also assess blood cultures x2, ABGs on room air, sputum culture and sensitivity, and asks that the client have a Mantoux test.

Ethnicity: Black American

Preexisting condition: Allergy to erythromycin and aspirin

Socioeconomic: Retired, lives at home with her husband, volunteers as a receptionist at a local adult community center, smokes a half of a pack of cigarettes per day, positive tobacco use for 54 years.

Mrs. Harriet’s EKG, shows normal sinus rhythm with a heart rate of 98 beats per minutes. The CXR reveals a right lower lobe infiltrate, Lab tests include the following results, WBC: 12,200 cells/mm³, 72% seg neutrophiles with a left shift of 11 % bands, and a BNP of 50.9 pg/ml. ABG’s on room air are pH 7.44, PaCO2 39 mm/Hg HCO3 26.9 mEq/L, Pa02 is 58 mmHg, and oxygen sat is 92%. Results of the sputum culture show Streptococcus pneumonia. The CPK, CPK-MB,and troponin are all within normal limits. Mrs. Harriet is five feet three inches tall and weights 224 pounts. On assessment, the nurse hears expiratory wheezes and rhonchi bilaterally with diminished lung sounds in the right base. Her thoracic expansion is equal but slightly decrease on inspiration. Accessory muscle retraction is not noted, and she does not exhibit central cyanosis. Capillary refill of the client’s nail beds is four seconds.

Mrs. Harriet is admitted with acute bronchitis and pneumonia. The physican prescribes oxygen via nasal cannula to keep the client’s oxygen saturation ≥ 95%, ceftrizxone sodium, erythromycin, albuterol, acetaminophen every four hours as needed, bed rest, increased oral fluid intake to 2-4 liters per day, coughing and deep breathing exercises, and use of an incentive spirometer.

1) Discuss the pathophysiology and symptoms of acute bronchitis.

2) Discuss the pathophysiology and causes of pneumonia in general

3) Compare the defining characteristics of community-acquired pneumonia, hospital acquired pneumonia and viral pneumonia.

4) Discuss the factors that place Mrs. Harriet at greater risk for the development of pneumonia

5) The nurse asks Mrs. Harriet if she has been using her incentive spirometer. Mrs. Harriet states, “I tried to use it a couple of times but I think it is broken. When I blow into it, the ball does not go up like I was told it should.” How should the nurse intervene?

6) Analyze Mrs. Harriet’s ABG results. Determine whether each value is high, low, or within normal limits; interpret the acid base balance; determine if there is compensation; and indicate whether the client has hypoxemia.

7) Provide a rationale for each of the following prescribed components of Mrs. Harriet’s treatment plan: oxygen saturation ≥ 95%, ceftrizxone sodium, erythromycin, albuterol, acetaminophen every four hours as needed, bed rest, increased oral fluid intake to 2-4 liters per day, coughing and deep breathing exercises, and use of an incentive spirometer.
