The nurse recognizes that which statement correctly characterizes drug absorption?
Drugs given subcutaneously are absorbed more quickly than those given intramuscularly.
Most drugs must enter the systemic circulation to have a therapeutic effect.
Most oral medications are absorbed more quickly when administered with meals.
Mucous membranes are relatively impermeable to chemicals, making absorption slow.
The Correct Answer is B
B. Drug absorption refers to the process by which a drug moves from its site of administration into the bloodstream. Once absorbed into the bloodstream (systemic circulation), drugs can distribute to various tissues and exert their therapeutic effects.
A. Different routes of drug administration affect the rate and extent of absorption. Subcutaneous injections are generally absorbed more quickly than intramuscular injections due to differences in blood flow and tissue characteristics.
C. The effect of meals on drug absorption varies depending on the specific medication. Some drugs are absorbed faster on an empty stomach, while others may be absorbed better with food.
D. Mucous membranes, contrary to the statement, are relatively permeable to drugs, allowing for rapid absorption when medications are administered via buccal, sublingual, rectal, or vaginal routes.

Correct Answer is A
Explanation
A. The JP drain helps prevent excessive accumulation of fluid in the wound by actively draining it away. If fluid were to accumulate excessively, it could impair wound healing and increase the risk of infection.
However, the primary purpose of the JP drain is to remove fluid rather than prevent its collection altogether.
B. The JP drain does not directly assess the degree of healing. Its primary function is to drain fluid from the wound to promote healing by preventing fluid accumulation, which could hinder healing. Assessing the degree of healing typically involves visual inspection of the wound by the healthcare provider rather than relying on the drain.
C. This is not the purpose of the JP drain. Healing generally occurs by the gradual migration of cells and tissues to close the wound, which is an internal process. The JP drain assists in the healing process by preventing complications due to fluid accumulation but does not influence healing from outside to inside.
D. While the JP drain itself does not directly prevent the entrance of microorganisms into the wound, it indirectly contributes to infection prevention by removing excess fluid. Accumulated fluid can provide a medium for bacterial growth, potentially leading to infection. By draining fluid effectively, the JP drain helps maintain a cleaner wound environment, reducing the risk of infection.
