A nurse is assessing a client's understanding of a surgical procedure prior to witnessing their signature on the informed consent form. The nurse determines that the client does not understand what the procedure will involve. Which of the following actions should the nurse take?

Choice A rationale:
Wearing gloves when changing the cat's litter box is essential during chemotherapy because some chemotherapy drugs can be excreted in bodily fluids, including feces. Protecting against direct contact with potentially harmful substances is crucial to minimize exposure risks.
Choice B rationale:
Taking the temperature once each week is not a relevant precaution during chemotherapy. Monitoring temperature is important, but it should be done more frequently, such as daily, as chemotherapy can cause immunosuppression, increasing the risk of infection.
Choice C rationale:
Being able to attend a concert is not related to precautions during chemotherapy. It is essential for clients undergoing chemotherapy to avoid large gatherings and events where they might be exposed to infections.
Choice D rationale:
Allowing the toothbrush to dry completely between each use is a good hygiene practice but not specifically related to chemotherapy precautions. Proper oral hygiene is essential during chemotherapy, but using a soft toothbrush and regularly replacing it are more relevant considerations.

Choice A rationale:

Severe headache can be a symptom of a subdural hematoma, but it is not the earliest manifestation of a change in neurological status. Other symptoms may appear before a severe headache, such as an altered level of consciousness.

Choice B rationale:

Bradycardia can occur with a subdural hematoma, especially as intracranial pressure increases. However, it is not the earliest manifestation of a change in neurological status. Changes in heart rate may occur later in the progression of the condition.

Choice C rationale:

Widened pulse pressure can also occur in patients with a subdural hematoma due to increased intracranial pressure. However, it is not the earliest manifestation of a change in neurological status. Other neurological signs would likely appear before changes in pulse pressure are evident.

Choice D rationale:

Change in level of consciousness is the earliest manifestation of a change in neurological status with a subdural hematoma. As intracranial pressure increases, the brain's functioning can be affected, leading to alterations in consciousness, ranging from mild confusion to unconsciousness.
