A client is newly prescribed calcium carbonate and asks how they should take this medication. What is the best response by the nurse?

A) Cerebral Vascular Accident (CVA): While a history of a CVA (stroke) is important to consider when prescribing medications, ondansetron is not contraindicated for clients with a history of CVA. The nurse would need to assess the client’s overall neurological status and risk factors but this condition is not an immediate concern for ondansetron use.

B) Depression: Ondansetron is not typically contraindicated in patients with depression. However, the nurse should be mindful of the potential for interactions with other medications the client may be taking for depression, but there is no direct contraindication between ondansetron and depression itself.

C) Glaucoma: This is the most concerning finding. Ondansetron can increase the risk of complications in clients with glaucoma, particularly narrow-angle glaucoma. Ondansetron has some serotonin receptor-blocking properties that can cause dilation of the pupil, which could increase intraocular pressure in clients with glaucoma. Therefore, this condition would require careful monitoring, and the nurse would need to consult with the healthcare provider before administering ondansetron to a client with glaucoma.

D) Congestive Heart Failure (CHF): While patients with CHF need to be monitored for fluid balance, ondansetron is not contraindicated in clients with CHF. The primary concern in these patients would be potential fluid retention or electrolyte imbalances, but this is generally not a direct concern for the administration of ondansetron itself.

A) Polyethylene Glycol: Polyethylene glycol is a medication typically used to treat constipation by promoting bowel movements. While it can be useful in managing constipation, it is not commonly prescribed after a myocardial infarction. In this situation, the focus is more on medications that promote heart health, reduce cardiac workload, and prevent complications related to the heart attack.

B) Bisacodyl: Bisacodyl is a stimulant laxative used to relieve constipation. However, this medication is not typically prescribed immediately following a myocardial infarction. Stimulant laxatives can cause dehydration and excessive fluid shifts, which can be harmful to a client recovering from a heart attack. The focus would be on safer options for bowel management in this context.

C) Senna: Senna is also a stimulant laxative, used for relieving constipation. Similar to bisacodyl, it is not ideal for clients who have recently experienced a myocardial infarction due to its potential for causing dehydration and electrolyte imbalances, which could negatively affect heart function. A gentler approach to bowel management is preferred for these clients.

D) Docusate Sodium: Docusate sodium is a stool softener commonly prescribed to prevent constipation, especially in clients who have recently had a myocardial infarction. After a heart attack, it's important to avoid straining during bowel movements, as this could increase pressure on the heart. Docusate sodium helps soften stools and promotes smoother bowel movements without stimulating the gastrointestinal system in a way that would elevate cardiac stress. It is the most appropriate choice for this client.
