A newly admitted hospice patient with metastatic lung cancer has expressive aphasia from a previous CVA. Vital signs are: BP 160/96 mm Hg, HR 92/min, and RR 22/min. They are moaning, refusing to be turned, and fidgeting with their bedsheets. The patient is clutching their throat, and there are white patches on the pharynx. Which of the following medications should the nurse administer FIRST?

While hydromorphone is an opioid analgesic that could provide pain relief, it does not address the underlying issue indicated by the white patches in the pharynx. Given the patient's potential discomfort and potential difficulty swallowing, providing an antifungal treatment is prioritized over pain management in this scenario.

Lisinopril is an antihypertensive medication used to manage high blood pressure. Although the patient presents with elevated blood pressure, treating the hypertension is not the immediate concern given the alarming signs of a possible fungal infection. Therefore, it is not appropriate to prioritize this medication in the context of the patient's current condition.

Lorazepam is a sedative that could help manage anxiety or agitation, which may be beneficial for the fidgeting behavior observed. However, addressing the potential oral thrush with an antifungal treatment is essential before managing anxiety, as the discomfort from the infection may be contributing to the patient's agitation.
