A nurse is teaching a client who has a new diagnosis of rheumatoid arthritis. Which of the following statements should the nurse include in the teaching?

B. Laryngeal edema, or swelling of the larynx (voice box), is a hallmark feature of severe anaphylaxis. It can lead to airway obstruction and respiratory distress, which are critical components of an anaphylactic reaction.

A Arrhythmias (abnormal heart rhythms) can occur as a result of various causes, including medications, but they are not specific to anaphylaxis. They may or may not be present during an anaphylactic reaction.

C. Hypertension (high blood pressure) is not a typical feature of anaphylaxis. Instead, hypotension (low blood pressure) is more commonly associated with anaphylactic shock, which is a severe form of anaphylaxis.

D. Fever is not typically associated with anaphylaxis. Anaphylactic reactions typically involve rapid onset of symptoms such as flushing, hives, swelling, respiratory distress, and potentially cardiovascular collapse, but not fever.

A Hyperthermia is a hallmark sign of thyroid storm due to the body's increased metabolic rate and inability to dissipate heat efficiently. High fever is a critical sign that should prompt immediate medical evaluation and treatment.

B. While fatigue and lethargy can occur in hyperthyroidism, they are not prominent features of thyroid storm. Individuals with thyroid storm typically exhibit agitation, restlessness, or even delirium due to the effects of excessive thyroid hormone on the central nervous system.

C. Bradycardia is not a feature of thyroid storm. Instead, individuals typically experience severe tachycardia, which can lead to palpitations, chest pain, and cardiovascular complications.

D. Thyroid storm is more commonly associated with hypertension rather than hypotension. Increased cardiac output and vascular resistance contribute to elevated blood pressure during thyroid storm.
