Study Notes
Stethoscope Contamination and Cleaning
- A study comparing an ethanol-based cleanser (EBC) with isopropyl alcohol pads found that all 99 stethoscopes cultured were positive for bacterial growth.
- Both EBC and isopropyl alcohol significantly reduced bacterial counts on stethoscope diaphragms, highlighting the need for regular cleaning.
- Regular cleaning of stethoscopes with EBC or isopropyl alcohol is essential to protect patients from potential organism transmission and reduce infection, according to implications for nursing practice.
- The study was published in the American Journal of Infection Control (Lecat, Cropp, McCord, & Haller, 2009).
- Pathophysiology of Hypertension: Blood pressure (BP) is determined by cardiac output (CO), peripheral vascular resistance (PVR), blood viscosity, and circulating blood volume.
- Several processes influence BP, including nervous system regulation, arterial baroreceptors and chemoreceptors, the renin-angiotensin-aldosterone mechanism, and the balance of body fluids.
- Factors that impair normal regulation of BP, such as sympathetic nervous system overstimulation, alterations in baroreceptors and chemoreceptors, and hormonal changes, may lead to hypertension.
- Types of Hypertension: Primary hypertension has an unknown cause, while secondary hypertension is a sign of another problem. Isolated Systolic Hypertension (ISH) occurs mainly in older adults and requires treatment to decrease cardiovascular disease risk.
- Lifestyle modifications are usually tried first for ISH, and if they fail, antihypertensive medication is added. Alcohol consumption in older adults can aggravate age-related hypertension, and guided relaxation has been shown effective in reducing high BP in older adults.
- Gerontological Issues: After age 55, controlling systolic BP is important to prevent heart disease and stroke, as diastolic pressure falls while systolic pressure continues to rise with age.
- Signs and Symptoms of Hypertension: Hypertension often presents no signs or symptoms other than elevated BP readings, earning it the moniker "silent killer." Patients are often diagnosed during unrelated health care visits.
- In a small number of cases, patients with hypertension may report symptoms such as headache, bloody nose, severe anxiety, or shortness of breath, but it is usually difficult to correlate these symptoms with the degree of BP elevation.
Diagnosis and Risk Factors of Hypertension
- Hypertension is diagnosed when the average seated BP is above prehypertensive levels of 120 to 139 systolic or 80 to 89 diastolic on two or more occasions.
- JNC 7 recommends routine tests before beginning therapy for high BP to identify organ or blood vessel damage.
- Tests include ECG, blood glucose level, serum potassium and calcium levels, lipoprotein profile, and triglyceride level.
- Risk factors for hypertension include genetic (nonmodifiable) and environmental (modifiable) factors.
- Nonmodifiable risk factors include family history, age, ethnicity, and diabetes mellitus.
- Modifiable risk factors include blood glucose level, activity level, smoking, salt and alcohol intake, and insufficient sleep.
- People with a family history of hypertension have almost twice the risk of developing hypertension.
- Plaque buildup in arteries and stiffening of blood vessels as people age can cause an increase in BP.
- African Americans have higher mortality and morbidity rates related to hypertension and are more likely to develop kidney failure.
- Chinese Americans are more sensitive to the effects of propranolol on heart rate and BP.
- Hypertension among Japanese, Korean, and Filipino Americans is influenced by lifestyle factors such as diet, stress, and immigration.
- Many adults with diabetes mellitus also have hypertension, increasing the risk of heart attacks, strokes, blindness, and kidney failure.

- Hypertension among Japanese, Korean, and Filipino Americans is influenced by lifestyle factors such as diet, stress, and immigration.
- Many adults with diabetes mellitus also have hypertension, increasing the risk of heart attacks, strokes, blindness, and kidney failure.
Nursing Care of Patients With Hypertension
- Hypertension prevalence ranges from 3% in those aged 18-39 to 65% in those aged 60 or older
- Highest occurrence: non-Hispanic blacks at 42.1%, followed by non-Hispanic whites at 28%, then Hispanics at 26%
- JNC 8 guidelines approach hypertension management differently from JNC 7, focusing on pharmacologic treatment thresholds and lifestyle modifications
- Lifestyle interventions recommended include dietary changes and participation in aerobic activity
- DASH diet alone reduced BP by 11.2/7.5 mm Hg, while with exercise and weight loss, reductions were 16.1/9.9 mm Hg
- Greater adherence to the DASH diet was associated with larger BP reductions independent of weight loss
- JNC 7 redefined normal and abnormal BPs for adults aged 18 and older
- Correct BP measurement is essential for accurate readings
- DASH diet emphasizes increasing intake of certain commonly available foods
- Hypertension is a condition where average of at least two or more readings on different dates is above prehypertension levels
- Blood pressure categories and measures are defined, with recommended follow-up
- Stethoscopes used by healthcare providers are contaminated with bacteria, and cleaning between patients is crucial to reduce transmission of organisms
