Which statement indicates that the nurse understands what the half-life of a drug means?
Drugs with a short half-life have a greater risk for toxicity
Half-life is not affected by renal or hepatic function
if a medication has a long half-life. dosage times can be longer intervals & the drug remains effective
Half of the effective portion of the drug is metabolized by the liver
The Correct Answer is C
C. The half-life of a drug refers to the time it takes for the concentration of the drug in the bloodstream to be reduced by half. If a medication has a long half-life, it means that it stays in the body for a longer period before being eliminated. This allows for less frequent dosing intervals while still maintaining therapeutic effectiveness.
A. Drugs with a short half-life are typically cleared from the body more quickly. While they may require more frequent dosing to maintain therapeutic levels, they do not necessarily have a greater risk for toxicity compared to drugs with longer half-lives. In fact, drugs with longer half-lives can accumulate in the body over time, potentially increasing the risk of toxicity.
B. The half-life of a drug can be significantly influenced by renal (kidney) and hepatic (liver) function. Impaired renal or hepatic function can prolong the half-life of a drug, leading to slower elimination and potentially increased risk of adverse effects.
D. This statement describes the concept of drug metabolism rather than the half-life. Drug metabolism refers to the biochemical alteration of drugs by enzymes, often occurring in the liver. The half-life, on the other hand, specifically relates to the elimination of the drug from the body.

Correct Answer is A
Explanation
A. Establishing a trusting relationship is crucial in nursing care, including when addressing spiritual distress. This intervention allows the nurse to create a safe space for the client to express their feelings, concerns, and spiritual beliefs. It fosters open communication and helps the nurse understand the depth of the client's distress, which is essential for providing effective support and care.
B. Understanding the client's belief system, including their beliefs in a Supreme Being or higher power, is important in addressing spiritual distress. This information helps the nurse provide culturally and spiritually sensitive care that aligns with the client's values and preferences. However, while important, this would typically follow establishing a trusting relationship as it involves a deeper understanding of the client's spiritual perspective.
C. This response may come from a well-intentioned desire to reassure the client, but it oversimplifies the client's concerns and does not address the root of spiritual distress. Spiritual distress is often complex and may involve existential questions, fears, or conflicts related to beliefs, meaning, and purpose.
Offering simplistic reassurances without addressing these deeper issues may not effectively alleviate the client's distress.
D. Spiritual distress is distinct from physical problems, although it can manifest with physical symptoms. Focusing solely on the physical aspects may overlook the spiritual and existential concerns that underlie the client's distress. While it's important to assess physical symptoms comprehensively, this approach does not directly address the spiritual distress identified by the nurse.
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.
