A nurse is assessing a client who has thyrotoxicosis after taking too high of a level of levothyroxine. Which of the following manifestations should the nurse expect?
Drowsiness
Heat intolerance
Bradycardia
Dry skin
The Correct Answer is B
Rationale:
A. Drowsiness is not typically associated with thyrotoxicosis; rather, clients are more likely to experience restlessness or insomnia.
B. Heat intolerance is a common symptom of thyrotoxicosis, reflecting the increased metabolic rate associated with excessive thyroid hormone levels.
C. Bradycardia is associated with hypothyroidism, not thyrotoxicosis. In thyrotoxicosis, tachycardia or palpitations are more likely.
D. Dry skin is a symptom of hypothyroidism, whereas in thyrotoxicosis, the skin may become warm, moist, and flushed.

Correct Answer is D
Explanation
Rationale:
A. Theophylline is a bronchodilator used in the management of asthma.
B. Montelukast is a leukotriene receptor antagonist that helps control asthma symptoms.
C. Prednisone is a corticosteroid used to reduce inflammation during an asthma exacerbation.
D. Propranolol is a non-selective beta-blocker that can cause bronchoconstriction and should be avoided in clients with asthma, as it may exacerbate their condition.
Correct Answer is C
Explanation
Rationale:
A. An increase in weight is typically a symptom of untreated or poorly managed hypothyroidism, not a therapeutic response.
B. A decrease in body temperature is associated with hypothyroidism, and an improvement in this condition should result in a normalization of temperature, not a decrease.
C. An increase in energy is a therapeutic response to liothyronine, as hypothyroidism often causes fatigue and low energy levels. Treatment with liothyronine should alleviate these symptoms and restore normal energy levels.
D. A decreased heart rate (bradycardia) is a symptom of hypothyroidism, and effective treatment should normalize the heart rate, not lower it further.
