8 - Tired All the Time Flashcards
List 2 symptoms of obstructive sleep apnea.
- Snoring (usually snore-silence-snore)
2. Tiredness
How would heart failure lead to a swollen ankle?
Heart would be unable to pump effectively, causing a backlog of fluid in the ankles
How many globin chains does hemoglobin have?
4 (2 alpha, 2 beta)
Describe how diseased lungs in COPD put strain on the heart.
Diseased lungs ->
Less oxygen in the blood ->
Heart must pump faster to compensate
What is edema?
Swelling due to excessive fluid accumulation
Why would lung problems lower blood oxygen?
Lungs are the site where oxygen is transferred from the air to the blood
Which hormones control the overall metabolic rate of the body?
Thyroid hormones
NSAIDs can irritate the gastric mucosa, causing bleeding and ulcers. What would be the effect on stools?
Become black and tar-like
Compare lack of physical energy and lack of psychological motivation.
Lack of physical energy: want to do things but can’t
Lack of psychological motivation: can do things but don’t
Note: often interact
Define anemia.
Lack of RBC or hemoglobin
Older age of onset, obesity, and lack of exercise are indicative of which type of diabetes?
Type 2
A patient can’t make enough hemoglobin. List 3 nutritional deficiencies that could cause this.
- Lack of iron
- Lack of vitamin B9
- Lack of vitamin B12
List 3 risk factors for obstructive sleep apnea.
- Male
- Obese
- 40+
How may patients reduce orthopnea?
Sleeping propped up or sitting on a chair
Orthopnea (breathlessness when lying down) is a symptom of late stage heart failure. Describe its mechanism.
Lying flat ->
Blood rushing into the torso ->
Accumulation of fluid in the lungs ->
Breathlessness
Define menorrhagia.
Abnormally high menstrual bleeding
What is the result of untreated type 1 diabetes?
Death
What blood test would determine if a patient is anemic?
Full blood count (FBC)
Type 2 diabetes is mostly due to insulin ___.
Resistance
Describe how diseased lungs in COPD may increase blood pressure.
Diseased lungs ->
Less oxygen in the blood ->
Heart pumps faster to compensate->
High blood pressure
Why would a patient with sleep apnea exhibit a snore-silence-snore cycle?
The pharynx repeatedly collapses, blocking the airway each time
Which investigation method would you use to monitor COPD?
Spirometry
List 2 drugs that protect against GI bleeding by neutralizing stomach acid.
- Antacids
2. PPIs (proton pump inhibitors)
List 3 mechanisms by which COPD obstructs the airways.
- Swelling of airways
- Accumulation of mucus
- Destruction of lung parenchyma
Explain how high glucose levels in urine lead to dehydration and thirst.
Glucose drains cells of water via osmosis ->
Excessive urine production ->
Dehydration and thirst
List 2 reasons why foot ulceration occurs in diabetic patients.
- NEUROPATHY causes numbness to injury
2. BLOOD VESSEL DAMAGE prevents healing from injury
List 3 mechanisms that can damage lung alveoli.
- Edema
- Fibrosis
- Infection
What is the most common pulmonary function test?
Spirometry
How would upper GI bleeding cause tiredness?
Blood loss -> Anemia -> Reduced oxygen levels in the body -> Slowed metabolism -> Tiredness
Why would iron deficiency cause anemia?
Iron is an integral component of hemoglobin
In COPD and asthma, which structure becomes swollen and filled with mucus?
Airways
List 2 long-term eye complications of type 2 diabetes.
- Retinopathy
2. Cataracts
At what stage of life do most cases of type 1 diabetes present?
Early
