Week 5 Hypertension,Hypotension& Orthosatic Hypotension Flashcards
Hypertension Risk Factors
- Cigarette smoking
- Obesity
- Heavy alcohol consumption
- Lack of exercise
- High blood cholesterol levels
Hypertension Classifications
Grade 1: Systolic: 140-159 Diastolic 90-99
Grade 2: Systolic: 160-179 Diastolic 100-109
Grade 3: Systolic: more than 180 Diastolic >110
Hypertension symptoms
- Usually asymptomatic
- Vague symptoms
headaches, dizziness - can lead to myocardial infarction, stroke,
Hypertension Nursing intervention
- Accurately measure BP
- Monitor, document and Report
- Support patient with changing high risk lifestyle factors- smoking, obesity
- Manage pain, anxiety
Hypotension
Blood pressure below normal range
systolic reading of 90mmH or under
Hypotension Symptoms
- Dizziness
- Agitation
- Confusion
- Fatigue
- Pallor
- Blurred or distorted vision
Hypotension associated
- Haemorrhage (loss of blood)
- Dehydration
- Heart disease arrhythmias
- Severe burns (loss of fluids)
Hypotension Medication
- Analgesics (morphine)
- Antihypertensive agents
- Psychotropic (antidepressant, sedative, tranquillizer)
Hypotension Nursing Intervenions
- Sit-Stand Step
- Re-positioning the patient
- Hydration
- Monitor, document and report
-Measure for orthostatic hypotension
CausesHypotension
- Dehydration as reduces blood volume
- Blood loss from trauma such as road accident
- Emotional stress
- Heart disease can inhibit the pumping action of the heart
Orthostatic Hypotension
1 A drop in systolic BP of 20mmHg or more (with or without
symptoms)
2. A drop to below 90mmHg on standing, even if the drop is less
than 20mmHg
3. A drop in diastolic BP of 10mmHg with symptoms
Orthostatic Hypotension Symptoms
- Dizziness
– Vagueness
– Visual disturbances
– Palpitations
-Light headedness - Pallor
- Feelings of weakness
Causes of orthostatic hypotension
- Taking certain medications for blood pressure, heart, mood and Parkinson’s disease.
- Dehydration due to not drinking enough fluids, vomiting or diarrhoea.
- Prolonged bed rest.
- Certain conditions e.g. diabetes, heart problems, Parkinson’s disease and anaemia.
- Excessive amounts of alcohol.
How to measure orthostatic hypotension
- Ask patient to lie down at least 5 minutes
- Measure blood pressure
- Ask patient to stand up and measure bp after standing in the first minute
- Measure the blood pressure again after the patient has been standing for 3 minutes
Nursing actions orthostatic hypotension
- Get out of bed slowly
– First sit up, then sit on the side of the bed, then stand up.
– Take your time when changing position, such as when getting up from a chair.
– Have something steady to hold onto when you stand up.
– Take it steady when walking or get support if you feel dizzy.
– Exercise gently before getting up (move your feet up and down and clench and unclench your hands) or after standing (march in place).
– Avoid standing still over a long time.
– Avoid taking very hot baths or showers.
– Try sleeping with extra pillows to raise your head.
