1 Hypertension Case Study

2 Chief Complaint The chief complaint is a brief statement of the reason why the patient consulted the physician, stated in the patient’s own words. In order to convey the patient’s symptoms accurately, medical terms and diagnoses are generally not used. The appropriate medical terminology is used after an appropriate evaluation (i.e., medical history, physical examination, laboratory and other testing) leads to a medical diagnosis.

3 Chief Complaint “I just moved to town, and I’m here to see my new doctor for a checkup. I’m just getting over a cold. Overall, I’m feeling fine, except for occasional headaches and some dizziness in the morning. My other doctor prescribed a low-salt diet for me, but I don’t like it!”

4 HPI The history of present illness is a more complete description of the patient’s symptom(s). Usually included in the HPI are: • Date of onset • Precise location • Nature of onset, severity, and duration • Presence of exacerbations and remissions • Effect of any treatment given • Relationship to other symptoms, bodily functions, or activities (e.g., activity, meals) • Degree of interference with daily activities

5 HPI Sam Street is a 62-year-old African-American male who presents to his new family medicine physician for evaluation and follow-up of his medical problems. He generally has no complaints, except for occasional mild headaches and some dizziness after he takes his morning medications.

6 He states that he is dissatisfied with being placed on a low sodium diet by his former primary care physician. He reports a “usual” chronic cough and shortness of breath, particularly when walking moderate distances (states, “I’m just out of shape”).

7 PMH The past medical history includes serious illnesses, surgical procedures, and injuries the patient has experienced previously. Minor complaints (e.g., influenza, colds) are usually omitted unless they might have a bearing on the current medical situation.

8 PMH Hypertension × 15 years Type 1 diabetes mellitus
Chronic obstructive pulmonary disease, Stage 2 (Moderate) Benign prostatic hyperplasia Chronic kidney disease

9 FH The family history includes the age and health of parents, siblings, and children. For deceased relatives, the age and cause of death are recorded. In particular, heritable diseases and those with a hereditary tendency are noted (e.g., diabetes mellitus, cardiovascular disease, malignancy, rheumatoid arthritis, obesity).

10 FH Father died of acute MI at age 71. Mother died of lung cancer at age 64. Mother had both HTN and DM.

11 SH The social history includes the social characteristics of the patient as well as the environmental factors and behaviors that may contribute to the development of disease. Items that may be listed are the patient’s marital status; number of children; educational background; occupation; physical activity; hobbies; dietary habits; and use of tobacco, alcohol, or other drugs.

12 SH Former smoker (quit 3 years ago; smoked 1 ppd × 28 years); reports moderate amount of alcohol intake. He admits he has been nonadherent to his low sodium diet (states, “I eat whatever I want.”) He does not exercise regularly and is limited somewhat functionally by his COPD. He is retired and lives alone.

13 Meds: The medication history should include an accurate record of the patient’s current use of prescription medications, nonprescription products, and dietary supplements. Because pharmacists possess extensive knowledge of the thousands of prescription and nonprescription products available, they can perform a valuable service to the health care team by obtaining a complete medication history that includes the names, doses, routes of administration, schedules, and duration of therapy for all medications, including dietary supplements and other alternative therapies.

14 Meds: Triamterene/hydrochlorothiazide 37.5 mg/25 mg po Q AM
Insulin 70/30, 24 units Q AM, 12 units Q PM Doxazosin 2 mg po Q AM Albuterol INH 2 puffs Q 4–6 h PRN shortness of breath Tiotropium DPI 18 mcg 1 capsule INH daily Salmeterol DPI 1 INH BID Entex PSE 1 capsule Q 12 h PRN cough and cold symptoms Acetaminophen 325 mg po Q 6 h PRN headache

15 ALL: Allergies to drugs, food, pets, and environmental factors (e.g., grass, dust, pollen) are recorded. An accurate description of the reaction that occurred should also be included. Care should be taken to distinguish adverse drug effects (“upset stomach”) from true allergies (“hives”).

16 All PCN—Rash

17 ROS In the review of systems, the examiner questions the patient about the presence of symptoms related to each body system. In many cases, only the pertinent positive and negative findings are recorded. In a complete ROS, body systems are generally listed by starting from the head and working toward the feet and may include the skin, head, eyes, ears, nose, mouth and throat, neck, cardiovascular, respiratory, gastrointestinal, genitourinary, endocrine, musculoskeletal, and neuropsychiatric systems.

18 The purpose of the ROS is to evaluate the status of each body system and to prevent the omission of pertinent information. Information that was included in the HPI is generally not repeated in the ROS.

19 ROS Patient states that overall he is doing well and just getting over a cold. He has noticed no major weight changes over the past few years. He complains of occasional headaches, which are usually relieved by acetaminophen, and he denies blurred vision and chest pain. He states that his shortness of breath is “usual” for him, and that his albuterol helps.

20 He denies experiencing any hemoptysis or epistaxis; he also denies nausea, vomiting, abdominal pain, cramping, diarrhea, constipation, or blood in stool. He denies urinary frequency, but states that he used to have difficulty urinating until his physician started him on doxazosin a few months ago.

21 Physical Examination The exact procedures performed during the physical examination vary depending upon the chief complaint and the patient’s medical history. In some practice settings, only a limited and focused physical examination is performed. In psychiatric practice, greater emphasis is usually placed on the type and severity of the patient’s symptoms than on physical findings. A suitable physical assessment textbook should be consulted for the specific procedures that may be conducted for each body system. The general sections for the PE are outlined as follows:

22 Gen (general appearance)
VS (vital signs)—blood pressure, pulse, respiratory rate, and temperature. In hospital settings, the presence and severity of pain is included as “the fifth vital sign, weight and height are included in the vital signs section here, but they are not technically considered to be vital signs. Skin (integumentary)

23 HEENT (head, eyes, ears, nose, and throat)
