A client with narcolepsy receives a new prescription for methylphenidate. Prior to administration of the medication, the nurse should review the medical record for which condition?

Choice A reason: Constipation is typically a symptom of hypothyroidism, not hyperthyroidism. If a client is taking too much levothyroxine, they are more likely to experience symptoms of hyperthyroidism, such as diarrhea, rather than constipation.

Choice B reason: Intolerance to cold is a common symptom of hypothyroidism, indicating that the thyroid hormone levels are too low. If the client is taking too much levothyroxine, they would more likely experience heat intolerance due to increased metabolic activity.

Choice C reason: Restlessness is a symptom of hyperthyroidism, which can occur if a client is taking too much levothyroxine. Excess thyroid hormone can lead to increased nervous system activity, causing symptoms such as restlessness, anxiety, and tremors.

Choice D reason: Decreased appetite is more commonly associated with hypothyroidism. In contrast, hyperthyroidism, which can result from taking too much levothyroxine, often leads to an increased appetite.

Choice A reason: Hypercholesterolemia, or high cholesterol, is not a primary concern when prescribing methylphenidate. While managing cholesterol levels is important for overall cardiovascular health, it does not directly interact with the administration of methylphenidate.

Choice B reason: Hypertension, or high blood pressure, is a critical condition to review before administering methylphenidate. Methylphenidate can increase blood pressure and heart rate, potentially exacerbating pre-existing hypertension. Monitoring and managing blood pressure is essential to prevent complications such as stroke or heart attack.

Choice C reason: Diabetes mellitus is important to manage, but it is not directly affected by methylphenidate. While some medications can influence blood sugar levels, methylphenidate primarily affects the central nervous system and cardiovascular system.

Choice D reason: Bronchitis, an inflammation of the bronchial tubes, is not a primary concern with methylphenidate use. Although respiratory conditions should be managed appropriately, they do not typically interact with the effects of methylphenidate.
