A nurse is providing discharge teaching for a client who is receiving treatment for genital herpes. Which of the following statements by the client indicates the effectiveness of the teaching?

Choice A reason: Cheyne-Stokes respirations, characterized by a pattern of irregular breathing with periods of apnea, can be a sign of brain stem compression due to increased intracranial pressure. However, it is not typically the first sign of deteriorating neurological status.

Choice B reason: Pupillary dilation, especially if it is unilateral, can indicate pressure on the cranial nerves due to increased intracranial pressure. It is a concerning sign but may not be the first to appear as neurological function deteriorates.

Choice C reason: An altered level of consciousness is often the first sign of deteriorating neurological status in a patient with increased intracranial pressure. Changes in consciousness can range from slight disorientation or confusion to complete unresponsiveness.

Choice D reason: Decorticate posturing, which involves abnormal flexion of the arms with extension of the legs, indicates significant brain injury and is a later sign of increased intracranial pressure, not typically the first sign.

Choice A reason: Constipation can be a side effect of many cancer treatments, including radiation therapy. However, it is not commonly associated with targeted radiation therapy to the neck. Constipation is more often related to opioid pain medications, decreased physical activity, or dietary changes that a patient may experience during cancer treatment.

Choice B reason: Decreased tear production is not a typical side effect of targeted radiation therapy to the neck. This condition, known as dry eye syndrome, is more commonly associated with radiation therapy that affects the eye or orbital area directly.

Choice C reason: Mouth ulcers, also known as mucositis, are a common adverse effect of radiation therapy to the neck. Radiation can damage the mucosal lining of the mouth, leading to painful sores that can affect a patient's ability to eat, speak, and swallow. These ulcers typically develop one to two weeks after starting treatment and may persist for some time after the treatment ends.

Choice D reason: Peripheral neuropathy, which involves damage to the peripheral nerves and often results in symptoms like numbness, tingling, or pain in the hands and feet, is not a common side effect of radiation therapy to the neck. It is more frequently associated with certain chemotherapeutic agents or radiation therapy to areas of the body where peripheral nerves are located.
