Risk Factors and Causes

- The exact cause of primary hypertension is unknown, but several factors can increase the risk of developing it, such as:

  • Age: Blood pressure tends to rise with age as the arteries become stiffer and narrower.
  • Family history: Hypertension tends to run in families and may have a genetic component.
  • Race: African Americans are more likely to develop hypertension than other races and may have more severe complications.
  • Obesity: Excess body weight puts more strain on the heart and increases the volume of blood that circulates.
  • Physical inactivity: Lack of exercise can lead to obesity, high cholesterol, diabetes, and other conditions that affect blood pressure.
  • Smoking: Smoking damages the lining of the arteries, reduces the oxygen in the blood, and increases the heart rate and blood pressure.
  • Alcohol: Drinking too much alcohol can raise blood pressure and damage the liver and kidneys.
  • Salt: Eating too much salt can cause the body to retain fluid and increase blood pressure.
  • Stress: Chronic stress can trigger the release of hormones that constrict the blood vessels and increase blood pressure.

- Secondary hypertension can be caused by various conditions or medications that affect the kidneys, adrenal glands, thyroid, heart, blood vessels, or nervous system. Some examples are:

  • Kidney disease: Impaired kidney function can affect the balance of fluid and electrolytes in the body and increase the production of renin, a hormone that raises blood pressure.
  • Adrenal disorders: Conditions such as Cushing's syndrome, pheochromocytoma, or hyperaldosteronism can cause excess production of cortisol, adrenaline, or aldosterone, hormones that affect blood pressure.
  • Thyroid disorders: Hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid) can alter the metabolism and cardiac output and affect blood pressure.
  • Heart defects: Congenital or acquired defects such as coarctation of the aorta, aortic valve stenosis, or patent ductus arteriosus can increase the resistance to blood flow and raise blood pressure.
  • Blood vessel disorders: Conditions such as vasculitis (inflammation of the blood vessels), arteriosclerosis (hardening of the arteries), or fibromuscular dysplasia (abnormal growth of cells in the artery walls) can narrow or damage the arteries and increase blood pressure.
  • Nervous system disorders: Conditions such as brain tumors, spinal cord injuries, or autonomic dysreflexia can affect the regulation of blood pressure by the nervous system.
  • Medications: Certain drugs such as oral contraceptives, steroids, nonsteroidal anti-inflammatory drugs (NSAIDs), decongestants, antidepressants, or stimulants can raise blood pressure as a side effect.

Explanation

<p>Correct answer. Maintaining a healthy weight and engaging in regular exercise are important lifestyle modifications for managing hypertension. Weight reduction and physical activity can help improve blood pressure control and overall cardiovascular health.</p>

Correct Answer is A

Explanation

<p>This option is incorrect. Obesity is a modifiable risk factor for hypertension. Weight reduction through lifestyle changes can contribute to blood pressure control.</p>

Correct Answer is C

Explanation

<p>This option is incorrect. Advancing age is a non-modifiable risk factor for hypertension.</p>

Correct Answer is B

Explanation

<p>This statement is correct. Reducing stress levels can help prevent hypertension, as chronic stress is associated with elevated blood pressure.</p>

Correct Answer is B

Explanation

<p>This option is incorrect. Salt intake is relevant for individuals of all ages, not just older adults. Excessive salt intake can affect blood pressure at any age.</p>

Correct Answer is C

Explanation

<p>This question is not relevant to identifying a modifiable risk factor, as ethnicity is a non-modifiable risk factor.</p>

Correct Answer is C

Explanation

<p>This option is incorrect. Stress can affect blood pressure in all individuals, regardless of family history. It is a modifiable risk factor that can be managed through stress-reduction techniques.Questions</p>

Correct Answer is C

Explanation

<p>This option is incorrect. Palpitations and increased heart rate are not typical symptoms of hypertension. These may be indicative of other cardiac conditions.</p>

Correct Answer is B

Explanation

<p>This option is incorrect. Mild chest discomfort is not a typical symptom of a hypertensive emergency. However, any chest pain should be evaluated promptly as it may be indicative of other cardiac issues.</p>

Correct Answer is A

Explanation

<p>This option is incorrect. Reduced urine output is not typically associated with target organ damage in hypertension. However, reduced urine output may occur in acute hypertensive emergencies, such as hypertensive nephropathy.</p>

Correct Answer is D

Explanation

<p>Correct answer. Atherosclerosis, the buildup of plaque in the arteries, is a common complication of uncontrolled hypertension. Hypertension can cause chronic damage to the blood vessel walls, promoting the development of atherosclerotic plaques, which further narrows and stiffens the arteries.</p>

Correct Answer is B

Explanation

<p>This option is incorrect. Changes in skin texture or color are not typical symptoms of hypertension.</p>

Correct Answer is A

Explanation

<p>This option is incorrect. Nosebleeds, in isolation, are not usually indicative of severe hypertension. However, chronic uncontrolled hypertension can lead to target organ damage and potentially life-threatening complications.</p>

Correct Answer is B

Explanation

<p>This option is incorrect. Reduced urine output and fatigue are more likely related to kidney damage and heart failure, respectively, rather than hypertensive encephalopathy.Questions</p>

Correct Answer is D

Explanation

<p>Correct answer. Blood pressure measurement is essential in diagnosing and classifying hypertension accurately. It helps healthcare professionals determine if a person&#39;s blood pressure is within the normal range or meets the criteria for hypertension diagnosis.</p>

<p>This option is incorrect. The client is not required to record daily activities and symptoms during the 24-hour monitoring period for ABPM. Instead, the device automatically records blood pressure readings at regular intervals throughout the day and night.</p>

<p>Correct answer. Creatinine and BUN (blood urea nitrogen) levels are essential markers used to assess kidney function in the context of hypertension diagnosis. Hypertension can lead to kidney damage, and these blood tests help identify any impairment in kidney function.</p>

<p>This option is incorrect. An ECG is used to assess the heart&#39;s electrical activity, regardless of exercise. ABPM, as previously explained, monitors blood pressure continuously over 24 hours, including during periods of rest and activity.</p>

<p>This option is incorrect. An ECG does not provide information on blood levels of sodium and potassium. Blood tests are used for evaluating electrolyte levels, not ECG results.</p>

<p>This option is incorrect. Prothrombin time (PT) and international normalizedratio (INR) are coagulation tests used to evaluate blood clotting, not kidney function or hypertension-related kidney damage.</p>

<p>This option is incorrect. Home blood pressure monitoring is a valuable complement to regular medical check-ups, but it does not replace the need for healthcare visits. Regular medical check-ups are essential for comprehensive hypertension management and monitoring other health parameters.QUESTION

Correct answer. Uncontrolled high blood pressure can lead to various complications, including stroke (brain damage due to reduced blood flow), heart attack (damage to the heart muscle), and kidney damage (nephrosclerosis). These are among the most serious and common complications of hypertension.

This option is incorrect. Tingling in the extremities is not a typical manifestation of hypertensive retinopathy. It may be related to other conditions, such as peripheral neuropathy.

This option is incorrect. Peripheral artery disease (PAD) is caused by atherosclerosis in the peripheral arteries and is not directly related to hypertensive heart disease.

This option is incorrect. Bone fractures are not directly related to hypertension or its complications.

This option is incorrect. Hypertensive crises are medical emergencies and require prompt medical intervention to lower blood pressure and prevent potential complications.

Correct answer. Hypertensive nephropathy refers to kidney damage caused by chronic high blood pressure. It can lead to chronic kidney disease (CKD), a progressive loss of kidney function over time.

This option is incorrect. Hypertensive retinopathy does not cause thyroid dysfunction.QUESTIONS

<p>This option is incorrect. Social interactions and maintaining a support system are essential for mental well-being. Limiting social interactions may lead to increased stress and feelings of isolation.</p>

This option is incorrect. Some antihypertensive medications, such as diuretics, may be best taken in the morning to avoid nighttime urination. However, the timing of medications should be discussed with the prescribing healthcare provider based on the specific medication regimen.

<p>This option is incorrect. Salty cheeses and processed meats are high in sodium and should be limited in the diet of individuals with hypertension.</p>

<p>This option is incorrect. Thiazide diuretics may cause increased urination initially, but this effect usually diminishes over time as the body adjusts to the medication.</p>

<p>Correct answer. Recording blood pressure readings and any symptoms in a journal is essential for effective self-monitoring. It provides valuable information for the healthcare provider to assess blood pressure control and make necessary adjustments to the treatment plan.</p>

<p>This option is incorrect. Replacing regular table salt with salt substitutes may lead to increased potassium intake, which can be problematic for individuals taking medications that affect potassium levels. The client should use salt substitutes with caution and consult their healthcare provider

No explanation

<p>This option is incorrect. Hypertension is influenced by both genetic and lifestyle factors, and poor dietary habits can exacerbate the risk.</p>
