Decreased thyrotropin receptor antibodies

Decreased free thyroxine index

Decreased triiodothyronine

Decreased thyroid-stimulating hormone (TSH)

Answer and Explanation

The Correct Answer is D

A. Decreased thyrotropin receptor antibodies: Graves' disease is characterized by the presence of thyrotropin receptor antibodies, so they are typically increased, not decreased.

B. Decreased free thyroxine index: Graves' disease typically results in increased levels of thyroid hormones, not decreased.

C. Decreased triiodothyronine: T3 levels may be elevated in Graves' disease due to increased thyroid hormone production.

D. Decreased thyroid-stimulating hormone (TSH): Graves' disease causes excessive thyroid hormone production, leading to suppressed TSH levels. TSH is typically low in hyperthyroidism because the thyroid gland is overactive and not being stimulated by the pituitary gland.

Correct Answer is B

Explanation

A. "DIC is characterized by an elevated platelet count." Incorrect; DIC typically causes thrombocytopenia.

B. "DIC is caused by abnormal coagulation involving fibrinogen." DIC involves widespread activation of coagulation factors leading to the formation of microthrombi and consumption of clotting factors like fibrinogen. Understanding the pathophysiology helps in managing DIC effectively.

C. "DIC is controllable with lifelong heparin usage." Heparin is not used in DIC management due to the risk of bleeding.

D. "DIC is a genetic disorder involving a vitamin K deficiency." DIC is not genetic and is not caused by vitamin K deficiency.

A. "Medication is usually not prescribed to treat oppositional defiant disorder. Let's discuss some behavioral strategies you can use." B. There are many medications that will help your child manage aggression and destructiveness. The health care provider will discuss them with you." C. "Medication is not used to treat this oppositional defiant disorder because it is behavioral in nature." D. "It's a common misconception that there is a medication available to treat every health problem."

Correct Answer is A

Explanation

A. "Medication is usually not prescribed to treat oppositional defiant disorder. Let's discuss some behavioral strategies you can use." Behavioral interventions are the mainstay of treatment for ODD. Medications are not typically recommended unless there are comorbid conditions like ADHD or aggression that do not respond to behavioral interventions alone.

B. There are many medications that will help your child manage aggression and destructiveness. The health care provider will discuss them with you: This statement is misleading as medications are not first-line for ODD.

C. "Medication is not used to treat this oppositional defiant disorder because it is behavioral in nature.": This is an oversimplification; while primarily behavioral, medications might be considered in certain cases.

D. "It's a common misconception that there is a medication available to treat every health problem.": This statement dismisses the possibility of appropriate medication when needed.
