When examining the abdomen as part of a lymphoreticular assessment, why is the patient asked to lie flat with their arms by their sides before you inspect and palpate?
- A To bring the liver and spleen upwards against the abdominal wall so their edges are easier to feel You picked ✕
- B To raise the pressure inside the abdomen so that ascites is easier to see You picked ✕
- C To relax the abdominal wall so that organ enlargement and tenderness can be felt more accurately You picked ✓
- D To reduce venous return so that the veins on the abdominal wall stand out more You picked ✕
- E To make the abdominal wall taut so that scars and small masses are easier to see You picked ✕
Correct!
Incorrect
The answer is C: To relax the abdominal wall so that organ enlargement and tenderness can be felt more accurately
Explanation
Why C is correct
See Epitrochlear Lymph Nodes. Option C is correct because lying flat with the arms resting by the sides relaxes the muscles of the abdominal wall. A relaxed wall lets your hand sink in gently, so inspection and palpation are more reliable and you can feel for tenderness, masses and an enlarged liver (hepatomegaly) or spleen (splenomegaly). In a lymphoreticular assessment this matters because blood and lymph disorders, such as lymphoma and leukaemia, can enlarge these organs. Tense muscles would hide an organ edge and make the patient guard (tighten up) against your hand, so you would miss a finding or cause discomfort. For the same reason, expose the abdomen only as far as you need to, keep the patient comfortable and warm your hands before you start. The head on a single pillow and the feet together are part of the same positioning.
- Position: Lie flat with the arms by the sides.
- Why: It relaxes the abdominal wall so you can feel for tenderness, masses, hepatomegaly and splenomegaly.
- Relevance: Blood and lymph disorders such as lymphoma and leukaemia can enlarge the liver and spleen.
Why the other options are incorrect
- A. To bring the liver and spleen upwards against the abdominal wall so their edges are easier to feel: The patient's position does not move the liver or spleen upwards against the abdominal wall, and organ edges are felt by relaxed abdominal muscles and correct palpation technique. This is not the purpose of the positioning. Your answer
- B. To raise the pressure inside the abdomen so that ascites is easier to see: Lying flat does not raise the pressure inside the abdomen in a useful way, and the aim is not to make ascites easier to see. If the abdomen looks distended, you assess for fluid separately. Your answer
- D. To reduce venous return so that the veins on the abdominal wall stand out more: Reducing venous return to make veins stand out is not the purpose of this position. Dilated veins on the abdominal wall are looked for on inspection whatever the position. Your answer
- E. To make the abdominal wall taut so that scars and small masses are easier to see: This is not why the patient lies flat with the arms by the sides; that position relaxes the abdominal wall rather than making it taut. A taut wall would make deep palpation harder, not more accurate. Your answer

A 46-year-old woman has found a firm lump in her right breast. Supporting her right arm with one hand, you palpate the armpit with the other and feel a firm, non-tender, mobile node behind the front fold of the armpit. Which option correctly names this group of nodes and explains why the finding matters?

A 61-year-old woman has unintentional weight loss and feels full quickly after eating. Palpating her neck from behind with it slightly flexed, you feel a hard, craggy, non-tender node in the hollow just above her left collarbone. Which interpretation best links this finding to the likely cause?
