Various sounds are heard when assessing a blood pressure. What does the second sound heard through the stethoscope represent?
Systolic pressure
Pulse pressure
Auscultatory gap
Diastolic pressure
The Correct Answer is D
A. Systolic pressure:
The first sound heard during blood pressure measurement corresponds to the systolic pressure, the pressure in the arteries when the heart is contracting.
B. Pulse pressure:
Pulse pressure is the numerical difference between the systolic and diastolic pressures but is not specifically represented by a sound in blood pressure measurement.
C. Auscultatory gap:
An auscultatory gap is a temporary disappearance of sounds during blood pressure measurement, typically occurring between the systolic and diastolic pressures. It is not directly associated with the second sound.
D. Diastolic pressure:
The second sound heard corresponds to the closure of the aortic valve, marking the beginning of diastole. This sound represents the diastolic pressure, which is the pressure in the arteries when the heart is at rest.

Correct Answer is D
Explanation
A. Every four hours:
Turning a client every four hours may not be frequent enough to prevent pressure ulcers, especially in individuals with physical limitations or recent surgical procedures.
B. Every hour:
Turning a client every hour might be too frequent for some patients, and it may disrupt their rest and sleep. The optimal frequency depends on the client's condition.
C. Every shift:
Turning a client every shift (which typically spans 8-12 hours) may not provide adequate prevention for pressure ulcers, especially if the client has limited mobility.
D. Every two hours:
Turning a client every two hours is a common practice to prevent pressure ulcers. This interval helps redistribute pressure on vulnerable areas, improving blood circulation and reducing the risk of skin breakdown.
Correct Answer is A
Explanation
A. Defining the legal scope of nursing practice:
The nurse practice act in each state defines the scope of practice for nurses, outlining what nurses can and cannot do within the legal boundaries of their profession. It specifies the duties, responsibilities, and limitations of nursing practice within that particular state.
B. Lobbying federal lawmakers to advance professional nursing:
While nursing organizations and associations may engage in lobbying efforts at the federal level, it's not a direct component of the state's nurse practice act.
C. Providing continuing education programs:
While states might require nurses to participate in continuing education for license renewal, the provision of continuing education programs itself is not a direct element of the nurse practice act.
D. Creating institutional policies for health care practices:
Institutional policies are typically developed by healthcare institutions or organizations and are separate from the state's nurse practice act.
