A client with seasonal allergies takes diphenhydramine at bedtime to help their symptoms. The client develops low hemoglobin low white blood cell counts which is otherwise unexplained. What type of reaction is the client experiencing?

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) Metoprolol XL: Metoprolol XL (extended-release) should not be crushed. Crushing extended-release formulations can result in the rapid release of the drug, leading to an overdose or adverse effects due to the immediate release of the full dose. The nurse should advise the client to swallow this medication whole.

B) Ibuprofen EC (enteric-coated): Enteric-coated medications should not be crushed. The enteric coating is designed to protect the stomach lining by preventing the medication from being released in the stomach. Crushing the tablet would destroy this protective mechanism and could irritate the stomach lining, leading to discomfort or ulceration.

C) Morphine ER (extended-release): Extended-release formulations of morphine should never be crushed. Crushing extended-release formulations can lead to a potentially fatal overdose because it releases the entire dose of medication at once. This can cause respiratory depression and other life-threatening effects.

D) Acetaminophen: Acetaminophen in its regular tablet form can be safely crushed if needed. Crushing acetaminophen does not affect its effectiveness or safety, and it is a non-extended-release formulation, making it safe for manipulation when necessary, such as for clients with difficulty swallowing. However, it's essential to verify with the specific prescription, as acetaminophen is also available in extended-release formulations, which should not be crushed.
