A client with a history of bipolar disorder is prescribed lithium. Which teaching point should the nurse emphasize?

Choice A reason: Hydromorphone, an opioid, poses a significant risk of respiratory depression by suppressing the brainstem’s respiratory centers. After four days, cumulative effects increase this risk, especially in opioid-naïve patients. Monitoring respiratory rate and depth is critical to prevent life-threatening hypoxia, making it the priority assessment.

Choice B reason: Constipation is a common hydromorphone side effect due to opioid-induced reduced gastrointestinal motility. While important, it is not life-threatening like respiratory depression. Monitoring bowel function is secondary, as respiratory compromise poses an immediate risk requiring urgent intervention in opioid therapy.

Choice C reason: Skin rash is a rare allergic reaction to hydromorphone, not a primary concern after four days of use. Respiratory depression is far more critical, as opioids directly depress respiratory drive, risking hypoxia, making rash assessment secondary to monitoring respiratory function.

Choice D reason: Nausea is a frequent hydromorphone side effect, often diminishing with continued use. While bothersome, it is not life-threatening compared to respiratory depression, which can cause rapid hypoxia. Monitoring respiratory status is the priority to ensure patient safety during opioid administration.

Choice A reason: A foreign body in the eye may cause irritation or damage but is not a contraindication for ketorolac, a nonsteroidal anti-inflammatory drug (NSAID) used for pain and inflammation. The nurse would ensure removal of the foreign body first, but ketorolac can be used post-removal if indicated.

Choice B reason: Radiation exposure, such as from UV light, may cause photokeratitis but is not a specific contraindication for ophthalmic ketorolac. The medication reduces inflammation and pain, which may be beneficial in such cases. The nurse should assess for other ocular conditions, but radiation exposure alone does not preclude its use.

Choice C reason: Chemical burns require immediate irrigation and specific treatments based on the chemical involved. Ketorolac may reduce pain and inflammation post-irrigation, but it is not contraindicated. The nurse should prioritize burn management, but chemical burns do not inherently prohibit ketorolac use compared to corneal abrasions.

Choice D reason: Corneal abrasions are a contraindication for ophthalmic ketorolac, as NSAIDs can delay corneal healing and increase the risk of complications like corneal ulceration. The nurse must review the medical record to confirm the absence of abrasions, as ketorolac is typically used for postoperative pain, not traumatic corneal injuries.
