Transcript Hypertension Case Discussion

Hypertension Case
Study
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.
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!”
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
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.
• 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”).
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.
PMH
• Hypertension × 15 years
• Type 1 diabetes mellitus
• Chronic obstructive pulmonary disease, Stage 2 (Moderate)
• Benign prostatic hyperplasia
• Chronic kidney disease
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).
FH
• Father died of acute MI at age 71. Mother died
of lung cancer at age 64. Mother had both HTN
and DM.
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.
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.
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.
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
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”).
All
• PCN—Rash
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.
• 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.
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.
• 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.
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:
• 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)
• HEENT (head, eyes, ears, nose, and throat)
• Lungs/Thorax (pulmonary)
