The nurse is preparing to administer promethazine (Phenergan) to a client who presents with acute vomiting. What information in the client's past medical history would alert the nurse to hold the medication?

The correct answer is D: Narrow-Angle Glaucoma. Promethazine can cause pupil dilation and increase intraocular pressure, which can worsen narrow-angle glaucoma and lead to a sudden increase in eye pressure, potentially causing vision loss. Therefore, the nurse should hold the medication in a client with narrow-angle glaucoma to prevent exacerbating the condition.

Choice A: Diabetes Mellitus - This condition does not directly contraindicate the use of promethazine for acute vomiting.
Choice B: Chronic Kidney Disease - Although caution may be needed in this population due to potential renal impairment, it is not a specific contraindication to hold promethazine.
Choice C: Iron Deficiency Anemia - This condition is not a contraindication for using promethazine in a client with acute vomiting.

In summary, the nurse should hold promethazine in a client with narrow-angle glaucoma due to the potential adverse effects on intraocular pressure.
