Understanding Hypertension

Definition and Causes:Hypertension, or high blood pressure, is a chronic medical condition where the blood pressure in the arteries is persistently elevated. Common causes include genetics, poor diet, lack of physical activity, obesity, excessive alcohol consumption, and stress.

Symptoms: Often referred to as the “silent killer,” hypertension may not present obvious symptoms for many years. When symptoms do occur, they may include headaches, shortness of breath, nosebleeds, or dizziness, which usually appear when blood pressure has reached a dangerously high level.

Risks and Complications: Chronic hypertension can lead to severe health complications such as heart disease, stroke, kidney damage, and vision loss. It’s a major risk factor for cardiovascular morbidity and mortality.

Managing Hypertension

While regular monitoring and consultation with a healthcare professional are crucial, here’s a basic overview of immediate management strategies for hypertension:

General Measures:

Diet: Adopt a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins. The DASH (Dietary Approaches to Stop Hypertension) diet is often recommended to help lower blood pressure.

Exercise: Engage in regular physical activity, such as 30 minutes of moderate-intensity exercise most days of the week. Activities like walking, cycling, and swimming are beneficial.

Weight Management: Achieving and maintaining a healthy weight can significantly reduce blood pressure. Even a small amount of weight loss can have a positive impact.

Stress Reduction: Implement stress management techniques such as deep breathing, meditation, or yoga to help control blood pressure.

Seeking Medical Attention:

If you experience severe headaches, chest pain, difficulty breathing, or symptoms of stroke, seek emergency medical attention immediately. A healthcare professional will conduct a thorough examination, which may include blood pressure monitoring, blood tests, and electrocardiograms (ECGs) to diagnose the condition and develop an appropriate treatment plan.

Additional Considerations:

Medication: Antihypertensive medications may be prescribed to help manage blood pressure. Common types include diuretics, beta-blockers, ACE inhibitors, and calcium channel blockers. Always consult with a healthcare professional before starting any medication.

Lifestyle Modifications: Consistent lifestyle changes are crucial in managing hypertension. This includes reducing sodium intake, limiting alcohol consumption, quitting smoking, and maintaining regular follow-ups with your healthcare provider.

Drug Therapy Protocol:

Drug Therapy Protocol for Hypertension:

Licensed Clinical Nurse Specialist (CNS) must consult with the Attending Physician or Nurse Practitioner (NP). Registered Nurse (RN) in specialized settings may proceed.

Drug	Form	Strength	Route of administration	Recommended dosage	Duration
Antihypertensive A	Tablet	50 mg	Oral	Start with 50 mg once daily, increase as needed to a maximum of 200 mg per day	For elderly patients (≥65 years), start with the lowest effective dose and monitor closely for adverse effects.

Provide Patient Medication Guide:Caution against abrupt cessation of medication to prevent rebound hypertension. Potential side effects include dizziness, fatigue, and gastrointestinal issues. In case of severe side effects, consult a healthcare professional immediately.

Technique for Measuring Blood Pressure Correctly

Prepare the Patient: Ensure the patient is relaxed and seated comfortably with their back supported and feet flat on the floor. The arm should be at heart level, resting on a table.

Equipment Check: Use a properly calibrated sphygmomanometer. Choose the appropriate cuff size – the cuff bladder should encircle at least 80% of the upper arm.

Applying the Cuff: Place the cuff on the bare upper arm, ensuring it’s snug but not too tight. The lower edge of the cuff should be about 1 inch above the elbow.

Taking the Measurement:

Manual Method: Place the stethoscope’s bell over the brachial artery. Inflate the cuff to 20-30 mmHg above the point where the pulse disappears. Slowly deflate the cuff, listening for the first (systolic) and last (diastolic) Korotkoff sounds.

Automatic Method: Follow the device’s instructions for positioning and starting the measurement.

Recording and Interpreting Results: Record the systolic and diastolic pressures. Multiple readings may be needed to confirm hypertension.

Note: Always follow specific guidelines provided by medical authorities or institutions for accurate blood pressure measurement.
