A client receives a prescription for ophthalmic ketorolac. Prior to administering the medication, the nurse should review the medical record for which condition?
Corneal abrasion.
Chemical burn.
Radiation exposure.
Foreign body.
The Correct Answer is A
Choice A rationale
Corneal abrasion is a contraindication for the use of ophthalmic ketorolac. Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that can delay healing and increase the risk of further damage to the cornea.
Choice B rationale
Chemical burns are not a primary contraindication for ophthalmic ketorolac. However, the treatment of chemical burns typically involves other specific interventions, and the use of ketorolac should be carefully considered.
Choice C rationale
Radiation exposure is not a direct contraindication for the use of ophthalmic ketorolac. The medication is used to reduce inflammation and pain, which may be beneficial in managing symptoms related to radiation exposure.
Choice D rationale
A foreign body in the eye is not a primary contraindication for ophthalmic ketorolac. However, the foreign body should be removed, and the eye should be thoroughly examined before administering any medication.

Correct Answer is A
Explanation
Choice A rationale
Lactulose is a synthetic sugar used to treat hepatic encephalopathy by reducing the absorption of ammonia in the intestines. Ammonia is a neurotoxin that can impair mental status in patients with liver dysfunction. By decreasing ammonia levels, lactulose helps improve cognitive function and mental status in patients with hepatic encephalopathy.
Choice B rationale
While lactulose can cause diarrhea as a side effect, the therapeutic goal in hepatic encephalopathy is not to reduce the number of liquid stools but to lower ammonia levels in the blood. The reduction in ammonia levels leads to improved mental status, not necessarily a reduction in liquid stools.
Choice C rationale
The ability to ambulate independently is not a direct therapeutic response to lactulose. The primary goal of lactulose therapy in hepatic encephalopathy is to improve mental status by reducing ammonia levels, not to enhance physical mobility.
Choice D rationale
Lactulose does not have a direct effect on urine output. Its primary mechanism of action is to reduce ammonia absorption in the intestines, thereby improving mental status in patients with hepatic encephalopathy.
Correct Answer is C
Explanation
Choice A rationale
Lansoprazole, a proton pump inhibitor (PPI), typically requires several weeks to achieve its full therapeutic effect. Notifying the healthcare provider for a dosage change after only one week is premature and not supported by clinical guidelines.
Choice B rationale
Auscultating bowel sounds and measuring abdominal girth are not directly related to the effectiveness of lansoprazole in treating GERD. These actions are more relevant for assessing gastrointestinal motility and potential complications like bowel obstruction.
Choice C rationale
Healing of erosive esophagitis with PPIs like lansoprazole usually takes several weeks. Advising the client that healing typically takes several weeks to occur is appropriate and aligns with the expected therapeutic timeline.
Choice D rationale
Lansoprazole should be taken before meals, not after, to maximize its effectiveness. Confirming that the client is taking the medication one hour after meals would not address the issue of symptom persistence.
