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 B
Explanation
B Leaning away from the client can convey disinterest, distraction, or a lack of engagement. It creates physical distance and may inhibit the client from feeling heard or valued. Thus, leaning away from the client can be a barrier to active listening as it diminishes the nurse's ability to fully attend to and understand the client's message.
A. An open posture, where the nurse's body is facing the client with arms uncrossed and relaxed, signals openness and receptivity. It encourages communication and shows the client that the nurse is engaged and attentive. Therefore, an open posture promotes active listening rather than serving as a barrier.
C. Eye contact is essential for effective communication and active listening. It demonstrates attentiveness, interest, and respect. Establishing eye contact helps the nurse to connect with the client and encourages them to continue sharing their thoughts and feelings. Therefore, eye contact supports active listening rather than hindering it.
D. Sitting squarely facing the client promotes engagement and shows that the nurse is focused on the client. It facilitates direct communication and helps the nurse to observe the client's nonverbal cues effectively. This posture encourages open dialogue and supports active listening rather than acting as a barrier.
Correct Answer is ["24"]
Explanation
For a client prescribed 2 grams of amoxicillin/clavulanic acid every 12 hours, and given that the medication is supplied in 500 mg capsules,
The client would need to take four capsules to meet the 2-gram requirement per dose. Since the medication is to be taken every 12 hours, this equates to two doses per day.
For a 3-day business trip, the client would need to take a total of 6 doses. Therefore, the client should take 24 capsules (4 capsules per dose multiplied by 6 doses) with them to ensure they have enough medication for the duration of their trip.
