Lecture 2.1 Flashcards
List health history red flags
1) Weakness and fatigue
2) Fever, chills, and night sweats
3) Weight change
What’s the difference between weakness and fatigue?
1) Weakness: denotes demonstrable lack of strength.
2) Fatigue: is more nebulous but it points toward a lack of energy
What can fatigue correlate with for each category? (psych, infection, endocrine, cardiac, respiratory, renal, hepatic, heme, and miscellaneous)
1) Psych: depression/anxiety
2) Infection: mono, TB, endocarditis
3) Endocrine disorders: hypothyroidism, adrenal insufficiency, DM (diabetes mellitus)
4) Cardiac: heart failure
5) Resp: chronic lung disease
6) Renal: CKD
7) Hepatic: liver failure, hepatitis
8) Heme: anemia
9) Misc: electrolyte imbalance, malignancy, nutritional deficit, medications (beta blockers)
1) Define pyrexia
2) What is it correlated with?
1) Elevated temp
2) Infection, trauma (surgery or crush injury), malignancy, drug rxn (SSRI overdose), and immune disorders
What point to temperature change?
Chills/shivers/rigors
What does true shaking raise concerns for?
Bacteremia.
What are night sweats correlated with?
Both TB, and malignancy
1) What temperature will immune compromised patients with sepsis have?
2) What else is this true for?
1) Fever may actually be absent or low
2) Recent ingestion of ASA, NSAIDS, and steroids; may also mask fever`
What is a benign cause of elevated temperature?
Menopause; can cause hot flashes
1) How much does temperature vary throughout the day?
2) What indicates low temp?
3) What indicates high temp?
4) When does temperature drop? What happens when there’s a fever?
1) ~1C throughout the day.
2) Hot flashes and sweating
3) Chills and “cold sweats”
4) Normally, temperature drops at night; when this phenomenon is affected by fever, pts experience night sweats
1) What two questions should you ask if a patient says their weight changed?
2) What does rapid weight gain over a few days indicate?
3) What does that indicate?
1) “Is this rapid or gradual? Is this intentional?”
2) More likely portends fluid retention.
3) Indicates potential for heart failure, nephrotic syndrome, liver failure, and venous stasis
What can induce chronic weight gain? (6 things)
Medications such as:
1) Tricyclic antidepressants
2) Insulin and sulfonylurea
3) *Contraceptives
4) *Glucocorticoids
5) *Some SSRI’s
6) Others
* = important
What can unintended weight loss raise suspicion of?
1) CA
2) Hyperthyroidism
3) HIV/AIDS
4) Anorexia nervosa/bulimia
5) GI absorption disease
6) Malnutrition
When should you investigate weight loss in a patient?
Weight loss of more than 5% over 6 months needs further investigation
How many Americans experience chronic pain?
How many experience acute pain every year?
1) 100 million Americans
2) 12%
1) How should you treat pain?
2) What should you do in your diagnoses?
1) Like any other complaint and ensure that you apprehend the 7 attributes of a symptom.
2) In your diagnoses, attempt to localize and define the pain – pinpointing its source
1) What does proper chronic pain management target?
2) Is pain a vital sign?
1) Targets ADLs, not a 1-10 score
2) Pain is not a vital sign.
What are the elements of health promotion?
1) Optimal weight, nutrition, diet
2) Blood pressure and dietary sodium
3) Exercise
1) What percent of adults are overweight in the US?
2) What about kids?
1) 69% of U.S. adults are overweight or obese (BMI > 25 lbs/in^2)
2) 15% of kids are overweight and 17% are obese
Why does obesity matter?
Increases risk of diabetes, heart disease, and numerous types of cancers
What percent of healthcare providers are willing to mention obesity risks to obese patients?
Only 65% of health care providers
What can reducing weight by 10% do?
Improve BP, lipids, glucose tolerance and reduce DM risk
What can the right patient education do?
Can pull someone from the brink of prediabetes
What should you measure and assess regarding weight and nutrition? What should you screen for?
Measure objective data and assess risk factors, so screen for metabolic syndrome
What are the indicators of metabolic syndrome? How many to make a diagnosis?
1) Waist circumference >/= 40 in in men and >/= 35 in women
2) Fasting glucose >/= 100
3) HDL < 40 in men and < 50 women
4) Triglycerides >/= 150
5) Blood Pressure >/= 130 over 85
-3 or more = diagnosis
What are the classifications of overweight and obese based on BMI?
1) Underweight < 18.5
2) Normal 18.5 – 24.9
3) Overweight 25 – 29.9
4) Obese I 30 – 34.9
5) Obese II 35 – 39.9
6) Extreme obesity >/= 40
-“Eighteen point five to twenty-five, then count by fives”
How do you calculate BMI?
Take lbs x 700 and divide by the height in inches twice
What is the second step in promoting weight?
Take a diet history and assess eating patterns.
(It sometimes helps to walk through the last 24hours of diet; don’t forget beverages)
What is the 3rd step of promoting weight loss?
Assess motivation to change
(You can use the “change model” in your book for this.
As an entre into this, you can use the 1-5 scale and have them describe their reasoning
Precontemplation contemplation preparation action maintenance)
When counseling a patient about weight, what should you do?
-Remember the 10% stat we learned
-A safe amount of wt loss is 0.5-2 lbs per week
-Strategies for promoting weight loss
-Start with daily walking
-Make one diet change at a time
-Celebrate successes!
What are the 4 steps of promoting optimal weight?
1) Measure objective data and assess risk factors – to this end, screen for metabolic syndrome
2) Take a diet history and assess eating patterns
3) Assess motivation to change
4) Provide counseling
What kind of diet should you recommend to a patient trying to lose weight?
-One which produces a calorie deficit of 500-1000 calories
(Intake of added sugars, solid saturated/trans fats, and refined grains make it difficult to achieve optimal nutrition!)
What are shortcuts to weight loss?
1) Cut out sugar
2) Exercise daily
3) Eat “real food”
4) Avoid liquid calories
5) Make one change in the diet category and one change in the exercise category per week
6) Celebrate your victories!
1) How much salt is too much?
2) How much do most Americans eat, and what is the biggest contributor of salt to a diet?
1) More than 2,300 mg per day
2) Most Americans eat 3,400 mg daily; the major contributor of salt is processed food
How much exercise should someone get a week?
At least 2 ½ hours / week of “moderate intensity exercise.”
Give examples of moderate intensity exercise
Hiking
Yard work
Dancing
Golfing
Cycling (slowly)
Weights
Walking
Stretching
More than 90% of the time, what is the cause of HTN?
Idiopathic
(Idiopathic = we don’t know)
What are some risk factors of HTN?
-Age > 40
-Genetic Hx
-Black ancestry
-Obesity and wt gain
-Excessive salt intake
-Physical inactivity
-Excessive ETOH use
What are some conditions that can cause secondary HTN?
1) Chronic Kidney disease
2) Renal artery stenosis
3) Pheochromocytoma
4) Cushing’s disease/syndrome
5) Hyperaldosteronism
6) Obstructive sleep apnea
7) Thyroid disease
8) Parathyroid disease
9) Coarctation of the aorta
1) What is the BP screening recommendation?
2) Who is at risk for high BP?
3) How often are they screened?
1) Grade A recommendation: strongly encouraging annual BP screening of adults aged 40 + and those with increased risk
2) BP 130-139/85-89, overweight or obese, or black ancestry
3) They are screened every 3-5 years
1) What is the general survey?
2) When does it begin?
3) What does it include?
1) The broad view of a patient.
2) The moment you lay eyes on the patient, but will continue to crystalize as you proceed through the interview and physical
3) Economic status, nutrition, genetic makeup, physical fitness, mood, sex, geographic location, age, and state of health/illness all contribute to this picture.
