Answer to Question 1

A
Venous congestion increases capillary hydrostatic pressure. Increased hydrostatic pressure causes edema by causing increased movement of fluid into the interstitial area. Osmotic and oncotic pressures involve the concentrations of solutes and can contribute to edema in other situations. Concentration pressure is not a nursing term.

Answer to Question 2

B
The Z-track is indicated when the medication being administered has the potential to irritate sensitive tissues. The Z-track method is not meant to reduce discomfort from the procedure. If a patient is allergic to a medication, it should not be administered. If a patient has additional subcutaneous tissue to go through, a needle of a different size may be selected.
