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. pH 7.25, PaCO2 61, HCO3 26
pH is decreased (acidosis).
PaCO2 is elevated (61 mmHg), indicating respiratory acidosis (increased CO2 retention). HCO3 is slightly elevated (26 mEq/L), compensating for the respiratory acidosis.
A. pH 7.45, PaCO2 35, HCO3 22
pH is within normal range (7.35-7.45).
PaCO2 is slightly lower than normal (35 mmHg), indicating mild respiratory alkalosis. HCO3 (bicarbonate) is within normal range (22 mEq/L).
C. pH 7.23, PaCO2 27, HCO3 25
pH is decreased (acidosis).
PaCO2 is lower than normal (27 mmHg), indicating respiratory alkalosis (which is unlikely in the context of morphine overdose with hypoventilation).
HCO3 is within normal range (25 mEq/L).
D. pH 7.54, PaCO2 59, HCO3 26
pH is increased (alkalosis).
PaCO2 is elevated (59 mmHg), indicating respiratory acidosis (consistent with hypoventilation). HCO3 is slightly elevated (26 mEq/L), compensating for the respiratory acidosis.
Correct Answer is A
Explanation
A. The psychomotor domain involves the development of physical skills and the ability to manipulate objects. When the client performs a return demonstration of using the incentive spirometer, they are demonstrating their ability to coordinate their muscles and movements to correctly operate the device. This includes actions such as inhaling deeply, maintaining proper technique, and achieving the desired lung volume.
B The cognitive domain pertains to the acquisition and application of knowledge and intellectual skills. Understanding how the incentive spirometer works, its purpose in improving lung function post-surgery, and the correct technique for using it all fall under cognitive learning. The client must grasp the
Rationale behind using the spirometer to promote effective breathing and prevent complications like atelectasis.
C. Imitation involves observing and copying someone else's actions. In the context of using an incentive spirometer, the initial demonstration by the nurse serves as a model for the client to imitate. After receiving instructions and observing the nurse's demonstration, the client imitates the correct technique during the return demonstration. However, imitation alone does not fully capture the learning domain demonstrated by the client.
D. The affective domain focuses on attitudes, values, beliefs, and emotions. While using the incentive spirometer involves physical and cognitive skills, it also involves motivation and willingness to engage in the activity as prescribed by the healthcare provider. This domain encompasses the client's commitment to following through with spirometer use as part of their recovery and adherence to the healthcare plan.
