                                  The	rectum	should	also	be	observed.	During	inspection,	look	for	any	bulg-

                                  Start	with	gentle	palpation	of	the	abdomen	and	watch	for	non-verbal	signs

                                  Palpate	for	any	obvious	organ	enlargement	or	mass.	A	pulsating	mass	felt	
                                  in	the	abdomen	should	not	be	palpated	further	and	the	provider	should	
                                  be	notified	of	the	finding	immediately.	These	masses	are	usually	felt	in	the	
                                  upper	abdomen.	Sometimes,	especially	in	thin	residents,	a	mass	in	the

                                  disorders	may	lead	to	dehydration,	malnutrition,	and	weight	loss	in	older	
                                  adults.	Abdominal	pain	and	gastrointestinal	upset	can	be	caused	by
