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 ["1700"]
Explanation
To calculate the time when a new IV bag will be needed, we can divide the total volume left in the bag by the infusion rate.
With 500 ml remaining and an infusion rate of 100 ml per hour, it will take 5 hours for the current bag to be depleted.
Since the report was given at 1200 (which is noon in military time), adding 5 hours brings us to 1700, or 5:00 PM.
Therefore, the nurse should expect to hang a new IV bag at 1700 hours in military time.
Correct Answer is D
Explanation
D. When clients perceive that the knowledge or information being presented is beneficial to their health outcomes, they are more likely to be motivated to learn. Understanding how the knowledge can improve their health, manage their condition, or prevent complications provides intrinsic motivation to engage in learning activities.
A. While health literacy is important for understanding health information, having a high level of health literacy alone does not guarantee motivation to learn. Motivation to learn is more about personal engagement and perceived relevance of the information to one's own health and well-being.
B. While this may provide motivation for compliance with treatment plans or learning specific self-care tasks required for discharge, it does not necessarily translate to a strong motivation to learn beyond immediate needs related to discharge.
C. Formal education may contribute to overall cognitive abilities and learning skills, but it does not automatically translate into motivation to learn in a healthcare context. Motivation to learn is more about personal interest, perceived relevance, and understanding the benefits of acquiring new knowledge.
