A nurse is teaching a client who has a new prescription for levothyroxine (T4) about thyrotoxicosis. The nurse should instruct the client to monitor and report which of the following findings?
Weight gain
Bradycardia
Fever
Drowsiness
The Correct Answer is C
A. Weight gain is a sign of hypothyroidism, not thyrotoxicosis.
B. Bradycardia is associated with hypothyroidism, whereas thyrotoxicosis causes tachycardia.
C. This is the correct answer. Fever is a symptom of thyrotoxicosis, which results from excessive thyroid hormone levels, leading to hypermetabolism. Other signs include tachycardia, anxiety, heat intolerance, and weight loss.
D. Drowsiness is more commonly associated with hypothyroidism.

Correct Answer is A
Explanation
A. A child who has acute epiglottitis and is drooling – This is the priority because drooling, stridor, and respiratory distress suggest airway obstruction, which is life-threatening. Immediate intervention is required to secure the airway.
B. A child who has a urinary tract infection and bright red blood in her urine – Hematuria can be concerning but is not immediately life-threatening.
C. A child who has mononucleosis and reports severe fatigue – Fatigue is common with mononucleosis but does not require immediate intervention.
D. A child who has Wilms' tumor and an abdominal mass – While Wilms' tumor is serious, it does not present an immediate airway or hemodynamic emergency.
Correct Answer is A
Explanation
A. Vital signs should be monitored every 15 minutes because naloxone has a short duration and the client may experience opioid re-sedation as the antagonist wears off.
B. Naloxone should be administered over 2 minutes, not 15 seconds, to reduce abrupt opioid withdrawal symptoms.
C. Naloxone has a rapid onset (1-2 minutes IV, 2-5 minutes IM).
D. The effects of naloxone last only 30-90 minutes, requiring repeated doses if opioids are still in the system.
