A nurse is caring for an adolescent who states, "I failed my math exam because the teacher doesn't like athletes." The nurse should identify that the adolescent is using which of the following defense mechanisms?

Choice A rationale:

Replace the IV pump's tubing. Replacing the IV pump's tubing is not the appropriate action when the IV pump screen is malfunctioning. Malfunctioning tubing does not typically affect the pump's screen or settings.

Choice B rationale:

Clear the settings and reset the IV pump. Clearing the settings and resetting the IV pump may not be effective if the screen is malfunctioning. It is important to ensure the accuracy and safety of IV fluid administration, and troubleshooting the screen is not a reliable solution in the case of a malfunction.

Choice C rationale:

Plug the IV pump's cord into a different outlet. Changing the outlet may help if the issue is related to electrical power, but it is not the most appropriate action when the IV pump screen is malfunctioning. Safety concerns and potential equipment issues warrant discontinuing use and tagging the pump.

Choice D rationale:

Discontinue use and tag the IV pump. When the IV pump screen is malfunctioning, the safest and most appropriate action is to discontinue its use and tag the pump. This ensures that the malfunctioning equipment is not used on other patients and that a thorough inspection and repair can be conducted to prevent potential harm to the patient.

Choice A rationale:

"Nervousness." Rationale: This is a correct instruction. Thyrotoxicosis is a condition characterized by excessive thyroid hormone production. Common symptoms include nervousness, anxiety, restlessness, and emotional instability. The client should notify the healthcare provider if they experience these symptoms as they may indicate an excessive dose of levothyroxine.

Choice B rationale:

"Cough." Rationale: Cough is not typically associated with thyrotoxicosis. Symptoms of thyrotoxicosis are primarily related to an overactive thyroid gland and may include palpitations, weight loss, heat intolerance, and nervousness.

Choice C rationale:

"Pruritus." Rationale: Pruritus (itching) is not a common symptom of thyrotoxicosis. Itchy skin is more likely related to other dermatological or systemic conditions and should be evaluated separately.

Choice D rationale:

"Polyuria." Rationale: Polyuria (excessive urination) can be associated with both hypothyroidism and hyperthyroidism, but it is not a typical manifestation of thyrotoxicosis. Increased urination is more commonly seen in conditions like diabetes mellitus. Therefore, polyuria alone may not be indicative of thyrotoxicosis in this context.
