A light is directed at a patient's pupil, which contracts. It is also noted that the other pupil contracts as well, though it is not exposed to bright light. Which term describes this phenomenon?

A. Spleen is incorrect because the spleen is assessed using bimanual palpation, beginning in the right lower quadrant and progressing diagonally toward the left upper quadrant. The spleen must enlarge significantly before it becomes palpable, and the hooking technique is not appropriate for detecting splenomegaly.

B. Liver is correct because the hooking technique is a specialized method used to palpate the liver edge, particularly in patients who are overweight, obese, or have increased abdominal muscle tone, where standard palpation may be difficult. In this technique, the examiner stands to the patient’s right, hooks their fingers under the right costal margin, and asks the patient to take a deep breath. As the patient inhales, the diaphragm descends and pushes the liver downward, allowing the examiner to feel the liver edge as it meets the fingertips. This method helps assess the size, consistency, and tenderness of the liver, which can indicate conditions such as hepatomegaly, cirrhosis, or liver congestion.

C. Kidney is incorrect because the kidneys are evaluated using deep bimanual palpation, with one hand placed under the flank and the other on the abdomen. The examiner attempts to “capture” the kidney between the hands during inspiration. The hooking technique is not used for kidney assessment.

D. Gallbladder is incorrect because the gallbladder is typically not palpable unless enlarged or inflamed. Instead, it is assessed using Murphy’s sign, where the patient experiences pain and inspiratory arrest during palpation of the right upper quadrant. The hooking technique does not apply to gallbladder evaluation.

A. Pulmonary hypertension is incorrect because it may produce a loud pulmonic component of S2 (P2) or possibly a murmur of pulmonic regurgitation, but it is not typically described as a classic blowing diastolic murmur best heard along the left sternal border.

B. Right sided heart failure is incorrect because it is a clinical syndrome, not a direct cause of a specific murmur. While it may be associated with murmurs such as tricuspid regurgitation, those are typically holosystolic, not diastolic.

C. Left sided heart failure is incorrect because, like right-sided failure, it is a condition rather than a specific valvular lesion. It may be associated with murmurs, but it does not directly produce a blowing diastolic murmur.

D. Aortic regurgitation is correct because it classically presents as a blowing, decrescendo diastolic murmur best heard along the left sternal border (2nd to 4th intercostal spaces). This murmur occurs due to backflow of blood from the aorta into the left ventricle during diastole, and is commonly seen in older adults due to degenerative valve changes.
