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

Answer and Explanation

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 B

Explanation

B. Activating a code blue or the facility's emergency response system will bring immediate assistance and resources to the client's bedside. This is crucial to initiate prompt resuscitative measures if indicated and to involve additional healthcare providers in the management of the emergency.

A. While it might be appropriate in some situations to provide privacy or support to the partner, in this urgent scenario where the client is unresponsive and not breathing, the priority should be immediate assessment and intervention for the client's condition.

C. While notifying the physician is important, especially to inform them of the client's condition and potentially discuss the DNR status, it is not the most immediate action in this urgent situation where the client is unresponsive and not breathing. Direct intervention and assessment are needed first.

D. Asking the partner to make a DNR decision immediately is not appropriate as the first action in this scenario. It is crucial to focus first on the client's immediate needs for assessment and potentially resuscitative measures if indicated. The discussion about the DNR order should occur in a timely manner but is secondary to addressing the client's current medical emergency.

A. Introductory B. Noncongruent C. Nonverbal D. Congruent

Correct Answer is D

Explanation

D. Congruent communication occurs when verbal and nonverbal messages are consistent with each other. In the scenario, the nurse's direct eye contact, pleasant expression, and verbal statement ("The colostomy looks good") appear to be aligned and supportive of each other. This demonstrates congruence in communication, where both verbal and nonverbal cues are reinforcing a positive message to the client.

A. Introductory communication typically refers to the initial phase of interaction where the nurse establishes rapport, introduces themselves, and sets the tone for the interaction. This does not directly apply to the nurse's actions described in the scenario of changing a client's colostomy bag.

B. Noncongruent communication occurs when there is a mismatch between verbal and nonverbal messages. In this scenario, the nurse makes direct eye contact, has a pleasant expression, and verbally reassures the client that "the colostomy looks good." If these nonverbal cues (eye contact, pleasant expression) are not aligned with the verbal message (reassuring statement), it would be noncongruent communication. However, based on the scenario, it seems the nurse's nonverbal cues (eye contact, pleasant expression) support the verbal message, so this option is less likely.

C. Nonverbal communication includes gestures, facial expressions, eye contact, body language, and tone of voice. In the scenario described, the nurse demonstrates nonverbal communication by making direct eye contact and having a pleasant expression while interacting with the client. Nonverbal communication is an important aspect of nursing care as it conveys empathy, reassurance, and attentiveness to the client's needs.
