MSN 5041: Adult Gerontology Advanced Critical Care Concepts for Intensivist in Acute Care II

Case Study #2

Chief Complaint

A 67-year-old African American male is transported via ambulance from a primary care clinic to

the nearest emergency room (ER) with a severely elevated blood pressure of 228/120

accompanied by confusion.

The emergency medical responders report that the patient has a long-standing history of

uncontrolled hypertension (HTN), type 2 diabetes mellitus (DM), and hypercholesterolemia. He

was seen by his primary care nurse practitioner (NP) who noted that the patient had an elevated

blood pressure of 230/120 associated with acute confusion. An ambulance was called to

transport the patient to the nearest ER.

History of Present Illness

The patient’s wife denies that the patient experienced weakness, paresis, or paralysis of

extremities, dysarthria, aphasia, or other signs that may indicate a stroke, but notes that the

patient started acting “strangely” at approximately 8pm the night before admission. This morning

he was confused about the day and year, and forgot many of the details of his daughter’s recent

wedding. She was concerned so she took him to the primary care office, where the NP called

911. She reports there is no recent history of trauma, falls, or substance abuse. She endorses that

the patient has hypertension and diabetes, as reported by the primary NP, and denies any history

of cancer or heart disease. She also reports that he stopped taking his blood pressure medications

approximately 6 months ago because they caused excessive fatigue. She is unsure if he is taking

his other prescribed medications.

Past Medical History: HTN, DM, Type II, High cholesterol

Past Surgical History: Per wife and the EMR, patient has never had surgery

Social History: Patient’s wife reports he has never smoked, does not drink, does not use drugs

Medications:

• No known allergies

• Lipitor 10mg PO daily

• Metformin 500mg PO BID

• Per EMR: He is prescribed Amlodipine 10mg PO daily and Toprol 50mg PO daily, but

has not filled his prescriptions for the last 6 months

General Survey The patient’s vital signs on admission to the ER are:

BP 228/116 mmHg

HR: 78 beats per minute, normal sinus rhythm on the monitor

RR: 18 breaths/min

O2 sats: 96% on room air

He is lethargic but easily arousable, disoriented to time and place, and therefore unable to give a

reliable history. Data is gathered from his wife and the electronic medical record (EMR).

Review of Systems

The patient is unable to answer all of the questions; some of the information is obtained from the

patient’s wife.

Constitutional: denies fever, chills

Cardiovascular: denies chest pain, chest pressure, SOB, palpitations

Pulmonary: denies SIB

GI: denies abdominal discomfort, unable to determine last bowel movement

GU: denies burning with urination

Musculoskeletal: denies pain of extremities

Neurological: the patient is unable to provide a timeline as to the onset of confusion; per wife the

patient started acting “strangely” after dinner – “quiet, non-communicative, not answering

questions – said he did not feel well, but would not elaborate”. This morning his wife was

concerned when he appeared dazed and confused. He was disoriented to day and time. Wife

reports acute changes to short – and -long term memory.

Endocrine: denies thirst, excessive urination or excessive hunger, does not check blood glucose

at home.

Physical Examination

Vital signs

Repeat blood pressure is 200/120 mmHg in both right and left arms

Temp 36.0 C oral

HR 78 beats per minute

RR 16 breaths per minute

O2 sats 95% on room air

Weight 90 kg

Height 5’10”

BMI 28.1

Constitutional: Obese male, appears stated age, lethargic, disoriented to time and place, oriented

to person, arouses easily, able to answer simple questions with a “yes” or “no”.

HEENT: Normocephalic, anicteric, fundoscopic examination reveals exudates and cotton wool

spots, consistent with grade III retinopathy, no carotid bruits, no thyromegaly, or thyroid

nodules.

Cardiovascular: S1, S2, no murmurs, no gallops, no rubs, +displaced PMI. Pulses are present

bilaterally +2+2 right and left dorsalis pedis and posterior tibial pulses.

Pulmonary: Respirations are even and unlabored, breath sounds are clear and equal throughout.

Gastrointestinal: Normoactive bowel sounds, abdomen is soft, non-tender, non-distended, no

hepatosplenomegaly, + left epigastric abdominal bruit – systolic diastolic bruit.

Skin: Warm and dry, no rashes or lesions noted.

Musculoskeletal: Nontender spine; +systolic-diastolic bruit – located at the mid to lower left of

the spine.

Neurological: Limited neurological examination due to the patient’s inability to follow

commands. Cranial nerves II-XII intact, however, unable to examine extraocular movements

due to the patient being unable to follow commands; otherwise grossly non-focal, able to move

both arms and legs; no facial asymmetry, no dysarthria.

Preliminary Diagnostic Results

12-lead ECG reveals NSR of 78 beats per minute; PR interval 0.14, QRS interval 0.06; QT

interval 0.40 with left ventricular hypertrophy.

CXR demonstrates borderline cardiac enlargement; negative for a widened mediastinum.

NECT: negative for bleeding; diffuse white matter changes consistent with cerebral

encephalopathy.
