Answer:
Option B, palpation
Step-by-step explanation:
Palpation is the physical examination technique in which the healthcare worker uses their hands and fingers to assess for expected or abnormal findings. Examples can include palpating the liver, palpating the trachea, palpating the lymph nodes, and palpating for lesions, lumps, and masses on common anatomical locations.
Auscultation is listening to anatomical locations and documenting the findings. Commonly auscultated are the abdominal areas for bowel sounds, and the chest area for the lung sounds and heart sounds.
Percussion can involve the hands and fingers but they are not the exclusive tools for the technique. This aspect of physical examination involves tapping on a body part, cavity, sinus, etc. and assessing for a sound, or pain or tenderness as reported by the patient.
Inspection is using the sense of vision and/or smell to assess aspects of the patient that deviate from what is expected. Maybe the patient looks blue or gray, which can be a sign of cyanosis where the patient's tissues are not getting enough oxygen. Maybe that have a foul stench emanating from their breath, which can indicate a number of conditions. Both examples can be assessed without touching the patient.
But, to get back to the answer, the assessment technique that involves touching the patient with fingers or hands is palpation.
