A client currently prescribed a medication highly metabolized by the CYP 450 recently began smoking due to a stressful life event. True or False: The level of medication will increase in this client.

A) Prepare and administer the prescribed antidote: Administering an antidote would only be appropriate if the medication error resulted in a harmful reaction that requires immediate reversal. Since the issue here is the timing of medication administration, it is more important to first assess the client for any immediate effects rather than administering an antidote, which might not be necessary at this stage.

B) Notify the charge nurse, the nurse manager, and the prescriber: While notifying the appropriate staff is crucial, the first action should be assessing the client for any safety concerns or complications resulting from the medication administration error. Immediate evaluation of the client's condition should take precedence over notification.

C) Assess and identify the presence of urgent safety issues: The first priority in this situation is to assess the client for any adverse effects or reactions due to the medication being administered too quickly. This could include monitoring for signs of toxicity, adverse reactions, or changes in vital signs that may indicate a potential risk to the client’s health. Once the client's status is assessed, further actions such as notifying other staff or completing an incident report can follow.

D) Complete an incident report detailing the error: While documenting the error in an incident report is necessary, this should not be the first step. The immediate priority is to ensure the client’s safety by assessing their condition, as an error in the timing of medication administration may result in unwanted side effects or complications that need to be addressed first.

A) Hypersensitivity reaction: A hypersensitivity reaction typically involves an immune response where the body reacts to a substance as if it were harmful, leading to symptoms like rashes, swelling, or difficulty breathing. However, low hemoglobin and low white blood cell counts are not typical signs of a hypersensitivity reaction. This would involve more common allergic symptoms like itching or swelling, rather than hematologic changes.

B) Paradoxical reaction: A paradoxical reaction refers to when a medication causes an effect opposite to the expected result. For example, a sedative causing agitation instead of sleepiness. While a paradoxical reaction can involve unexpected effects, the hematologic changes (low hemoglobin and white blood cell counts) in this scenario do not align with this type of response.

C) Idiosyncratic reaction: An idiosyncratic reaction is an unusual or unexpected response to

a medication that is not related to the drug's pharmacologic properties or the dose given. It may be related to genetic factors or other individual differences in how a person metabolizes or responds to the drug. The low hemoglobin and low white blood cell counts in this case are unusual effects of diphenhydramine and suggest an idiosyncratic response, where the client’s body is reacting in an unexpected way to the medication.

D) Anti-cholinergic reaction: Anti-cholinergic reactions are typically related to symptoms caused by the blocking of acetylcholine, such as dry mouth, blurred vision, urinary retention, or constipation. While diphenhydramine has anti-cholinergic properties, the symptoms described (low hemoglobin and white blood cell counts) are not typical of an anti-cholinergic reaction.
