A client with a family history of cardiac disease is seeking information to control risk factors. Which lifestyle modification is most important for the nurse to encourage?

Choice A reason: Continuing the blood pressure assessment until the last Korotkoff sound is heard is not the best action to implement next. It may result in an inaccurate measurement of the diastolic pressure, as the cuff pressure may be too low to detect the sound.

Choice B reason: Repositioning the stethoscope in the antecubital fossa over the palpable brachial pulse point is not a necessary action to implement next. It may not affect the accuracy of the blood pressure measurement, as the nurse already hears the Korotkoff sounds clearly.

Choice C reason: Inflating the cuff quickly to a higher mm Hg reading than the previously auscultated systolic sound is not a safe action to implement next. It may cause discomfort and injury to the client, as the cuff pressure may be too high and occlude the blood flow.

Choice D reason: Releasing the air and reinflating the cuff to 30 mm Hg above the client's previous systolic reading is the best action to implement next. It helps to avoid the auscultatory gap, which is a period of silence between the systolic and diastolic pressures. It also ensures that the cuff pressure is high enough to detect the true systolic and diastolic pressures.

Choice A reason: Smoking cessation is the most important lifestyle modification for the nurse to encourage. Smoking is a major risk factor for cardiac disease, as it increases blood pressure, heart rate, and oxygen demand, and damages the blood vessels and the heart muscle. Quitting smoking can reduce the risk of cardiac disease by 50% within one year.

Choice B reason: Regular exercise is a beneficial lifestyle modification for the nurse to encourage, but not the most important one. Exercise can improve cardiovascular fitness, lower blood pressure, and reduce body weight, but it does not eliminate the harmful effects of smoking on the heart and blood vessels.

Choice C reason: A low-fat diet is a helpful lifestyle modification for the nurse to encourage, but not the most important one. A low-fat diet can lower cholesterol levels and prevent atherosclerosis, but it does not reverse the damage caused by smoking to the heart and blood vessels.

Choice D reason: Stress reduction is a useful lifestyle modification for the nurse to encourage, but not the most important one. Stress can trigger the release of hormones that increase blood pressure, heart rate, and oxygen demand, and can also lead to unhealthy behaviors such as smoking, overeating, and alcohol abuse. However, stress reduction alone does not address the direct effects of smoking on the heart and blood vessels.
