A nurse is contributing to the plan of care for a client who is experiencing delirium. Which of the following interventions should the nurse recommend?

Headaches are a common side effect of isosorbide dinitrate, especially when initially starting the medication. However, they often improve as the body adjusts to the medication. It is important to reassure the client that the headaches should decrease over time. If the headaches persist or worsen, the client should inform their healthcare provider for further evaluation and possible adjustment of the medication regimen.

The statement about taking the medication on an empty stomach is not relevant to preventing headaches associated with isosorbide dinitrate.

The statement about swallowing the tablet whole does not address the issue of headaches. Chewable isosorbide dinitrate is designed to be chewed or dissolved in the mouth, and swallowing it whole may not provide the intended therapeutic effect.

Discontinuing the medication until the headache goes away is not recommended without consulting the healthcare provider. Abruptly stopping or changing the dose of isosorbide dinitrate can have serious consequences and should only be done under medical supervision.

Restlessness can be an indicator of unrelieved pain in a client who is receiving a spinal epidural to treat a herniated disc. Restlessness is often a manifestation of discomfort or agitation, which can be caused by inadequate pain management. When a client's pain is not adequately relieved, they may exhibit restlessness as they try to find a more comfortable position or seek relief from the discomfort.

Urinary retention (option A) is incorrect because it can be a side effect of certain medications used in pain management, such as opioids, but it is not a specific indicator of unrelieved pain. It is important to monitor for urinary retention as a potential complication of spinal epidural anaesthesia, but it is not directly related to pain relief.

Constipation (option B) is incorrect because it is another possible side effect of opioid medications, but it is not a specific indicator of unrelieved pain. It is important to address constipation as a potential adverse effect of pain management, but it is not a direct indicator of pain relief.

Difficulty swallowing (option C) is incorrect because it is not a common indicator of unrelieved pain in the context of a spinal epidural. It may be associated with other conditions or complications but is not specifically related to pain relief.
