Correct Answer is D
Explanation
A. Osmolality: Osmolality measures the concentration of solutes in the blood and is not typically affected by naproxen or indicative of the reported symptoms.
B. Serum calcium: While naproxen can cause gastrointestinal irritation and ulceration, it does not typically affect serum calcium levels. Monitoring serum calcium would not directly address the client's reported symptoms.
C. Erythrocyte sedimentation rate (ESR): ESR is a nonspecific marker of inflammation and is not directly related to the reported symptoms of stomach pain, weakness, and fatigue associated with naproxen use.
D. Hemoglobin: Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), can cause gastrointestinal bleeding, which may lead to anemia and a decrease in hemoglobin levels. Monitoring hemoglobin levels can help assess for gastrointestinal bleeding in this client who is experiencing stomach pain and weakness/fatigue.
Correct Answer is C
Explanation
A. A sluggish blood return: While a sluggish blood return may indicate potential issues with the IV line, it does not require immediate intervention unless accompanied by other signs of
complications.
B. Cool sensation above the site: Cool sensation above the site may indicate impaired circulation, but it is not as concerning as other findings requiring immediate intervention.
C. Iced streak tracking the vein: Correct! An iced streak tracking the vein suggests infiltration of IV fluids into the surrounding tissue, which can cause tissue damage and compromise the
effectiveness of the IV therapy. Immediate intervention is needed to prevent further complications.
D. Circumferential skin irritation: Circumferential skin irritation may indicate an allergic reaction or contact dermatitis, which requires attention but is not as urgent as an infiltration.
