Will protect the pt from getting an infection B. May cause weight loss by decreasing appetite C. Is not curative but does cause a suppression of the inflammatory process D. Is relatively slow in precipitation a response but is effective in reducing sx

Is not curative but does cause a suppression of the inflammatory process ***Rationale: Rx inhibits phagocytosis & suppresses other clinical phenomena of inflammation; symptomatic tx that is not curative

A pt is admitted with the dx of acute pancreatitis. For which clinical manifestations should a nurse assess the pt? (Select all that apply) A. Jaundice B. Acute pain C. HTN D. Hypoglycemia E. Increased amylase

Jaundice, acute pain, & increased amylase ***Rationale: Obstruction of the common bile duct by inflammation leads to jaundice. Autodigestion of the pancreas causes severe ABD pain. Obstruction of the pancreatic duct leads to elevated levels of amylase & lipase.

The nurse is caring for a pt with arthritis. The pt asks, "Can I take Tylenol instead of ASP? ASP irritates my stomach." The nurse explains that Acetaminophen (Tylenol): A. Lacks anticoagulant action B. Has the same action as ASP C. Lacks an anti-inflammatory action D. Has more severe SE than ASP

Lacks an anti-inflammatory action ***Rationale: Although Tylenol reduces pain, it lacks anti-inflammatory action needed to limit joint inflammation with arthritis.

A pt is admitted to the high-risk prenatal unit with the dx of placenta prevue. What should the nurse instruct the pt to do? A. Breathe deeply to ensure that the fetus gets O2 B. Keep movement to a minimum to diminish bleeding C. Remain on her back to minimize pressure on the cervix D. Lie on her side to avoid putting pressure on the vena cava
