The nurse is teaching a patient, newly diagnosed with primary hypertension, about the recommended blood pressure range needed to prevent organ damage. Which range, chosen by patient, indicates that the teaching was successful?

A. Systolic BP between 120 and 160 mmHg:
While this range represents a moderate level of blood pressure control, it may not be optimal for preventing organ damage in individuals with primary hypertension. Systolic blood pressure (SBP) between 120 and 160 mmHg is considered elevated and may still increase the risk of cardiovascular complications over time. While it's not dangerously high, it's not within the recommended range for preventing organ damage associated with hypertension.

B. Diastolic BP between 70- and 99-mm Hg:
This range for diastolic blood pressure (DBP) is relatively broad and encompasses normal to elevated levels. While DBP between 70 and 99 mmHg is generally considered within the normal to prehypertensive range, it may not fully reflect the target range recommended for preventing organ damage in individuals with hypertension. The upper limit of 99 mmHg is higher than the optimal target range for preventing hypertension-related complications.

C. Diastolic BP between 60- and 79-mm Hg:
This range represents the optimal target for diastolic blood pressure (DBP) in individuals with hypertension. Keeping DBP between 60 and 79 mmHg is associated with reduced risk of cardiovascular events and end-organ damage. It aligns with current guidelines for blood pressure management and reflects successful teaching regarding the recommended range needed to prevent organ damage in patients with primary hypertension.

D. Systolic blood pressure between 90 to 120 mm Hg:
This range represents the optimal target for systolic blood pressure (SBP) in individuals with hypertension. Maintaining SBP between 90 and 120 mmHg is associated with the lowest risk of cardiovascular events and complications. It aligns with current guidelines for blood pressure management and reflects successful teaching regarding the recommended range needed to prevent organ damage in patients with primary hypertension.

A. Drink purified water: While drinking purified water is important for preventing various waterborne diseases, it is not a preventive measure specifically targeted at hepatitis B virus (HBV) transmission. HBV is primarily transmitted through exposure to infected blood or body fluids, such as during unprotected sex, sharing needles, or from mother to child during childbirth. Drinking purified water does not protect against these modes of HBV transmission.

B. Avoid crowded, enclosed spaces: Avoiding crowded, enclosed spaces may reduce the risk of respiratory infections, but it does not specifically prevent HBV transmission. HBV is not transmitted through the air like respiratory viruses. Instead, it is spread through direct contact with infected blood or body fluids. While avoiding crowded spaces may be a general infection control measure, it is not a targeted preventive measure for HBV.

C. Complete the vaccination series: This is the correct preventive measure for HBV. The hepatitis B vaccine is highly effective in preventing HBV infection. It is administered as a series of shots, typically given in three doses over a period of several months. Completing the vaccination series provides long-term immunity against HBV infection and is recommended for all individuals, including travelers to regions where HBV is common. Vaccination not only protects the individual but also contributes to reducing the overall prevalence of HBV in the community.

D. Avoid sharing utensils: While avoiding sharing utensils can reduce the risk of transmitting certain infections, such as colds or flu, it is not specifically aimed at preventing HBV transmission. HBV is primarily transmitted through activities involving exposure to infected blood or body fluids, rather than through sharing utensils. While practicing good hygiene and avoiding behaviors that may result in exposure to blood or body fluids are important preventive measures for HBV, completing the vaccination series is the most effective way to prevent infection.
