Correct Answer: D

Rationale: Palpating the midclavicular line is the correct technique for assessing the apical pulse. The apical pulse is located at the point of maximal impulse (PMI), which is typically at the fifth intercostal space at the midclavicular line. This technique allows healthcare providers to accurately assess the heart rate and rhythm by listening to the heart sounds directly at this point.

Correct Answer: A

Rationale: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure. In this case, the systolic pressure is 150 and the diastolic pressure is 96. Therefore, the pulse pressure is 150 - 96 = 54. Pulse pressure represents the force generated by the heart with each contraction and is an important indicator of cardiovascular health.

Correct Answer: A

Rationale: Proper hand washing for 30 seconds is recommended after routine patient contact as it effectively removes pathogens. This duration ensures thorough cleaning without excessive time consumption, promoting infection control and prevention.
