A client receives a prescription for ophthalmic ketorolac.
Prior to administering the medication, the nurse should review the medical record for which condition?

Drinking plenty of water whenever thirsty is not the most appropriate action for a patient with hypernatremia. While it's important to stay hydrated, excessive water intake can potentially worsen hypernatremia by diluting blood sodium levels further. This is because the body tries to balance sodium levels by either retaining water or excreting it through urine. In hypernatremia, the body is already short on water relative to sodium, so consuming too much water can exacerbate the imbalance.

Choice B rationale:

Reviewing food labels for sodium content is crucial for managing hypernatremia. It empowers patients to make informed choices and limit their sodium intake.

Sodium is a major contributor to hypernatremia, and reducing dietary sodium intake is a key strategy to lower blood sodium levels.

By carefully reading food labels and selecting low-sodium options, patients can effectively manage their sodium intake and promote a gradual return to normal sodium levels.

This approach addresses the root cause of hypernatremia and promotes long-term control of blood sodium levels.

Choice C rationale:

Monitoring daily urine output volume can be helpful in tracking fluid status, but it's not the primary action for managing hypernatremia.

While urine output can provide insights into fluid balance, it doesn't directly address the underlying issue of excessive sodium. Focusing on dietary sodium intake is a more direct and effective approach to correcting hypernatremia.

Choice D rationale:

Using salt tablets after strenuous exercise is not recommended for patients with hypernatremia.

Salt tablets are intended to replenish electrolytes lost through sweating, but they can worsen hypernatremia by further increasing sodium levels.

Patients with hypernatremia should focus on reducing sodium intake, not increasing it.

Rationale for Choice A:

Observing for edema around the ankles is a relevant assessment, but it's not the most crucial one in this context. Edema can be a sign of fluid retention, which is a potential side effect of hydromorphone. However, it's not the most immediate or dangerous concern associated with prolonged hydromorphone use.

Rationale for Choice B:

Counting the apical and radial pulses simultaneously is a technique used to assess for pulse deficits, which can indicate heart rhythm irregularities. While hydromorphone can potentially cause cardiac effects, it's not the most common or primary concern with its use. Other assessments take priority.

Rationale for Choice C:

Measuring the patient's capillary glucose level is important for patients with diabetes or those at risk for hyperglycemia. However, there's no direct link between hydromorphone use and blood glucose levels. This assessment isn't the most relevant in this specific scenario.

Rationale for Choice D:

Auscultating the patient's bowel sounds is the most important assessment for a patient who has been receiving hydromorphone for four days. Here's why:

Hydromorphone is a potent opioid analgesic that can significantly slow down gastrointestinal motility. This can lead to constipation, which, if severe, can progress to ileus (a complete lack of bowel movement).

Ileus is a serious complication that can cause abdominal pain, bloating, nausea, vomiting, and even bowel obstruction or perforation if left untreated.

Auscultating bowel sounds helps assess the patient's bowel activity and detect early signs of constipation or ileus. Normal bowel sounds are typically heard every 5-15 seconds. Decreased or absent bowel sounds can indicate decreased bowel activity.

Early identification of constipation or ileus allows for prompt intervention, such as increasing fluid and fiber intake, administering laxatives or stool softeners, and potentially discontinuing or adjusting the hydromorphone dosage. This can prevent the development of more serious complications.

Therefore, auscultating the patient's bowel sounds is the most important assessment for the nurse to complete in this case, as it directly addresses the most significant potential complication associated with prolonged hydromorphone use.
