The nurse is obtaining a medical history from a client scheduled for a thyroid diagnostic test. Which of the following findings may affect the results?

A diagnosis of schizophrenia.

The client is taking a prescribed oral contraceptive.

The client takes vitamin C daily.

A history of obesity.

Answer and Explanation

The Correct Answer is B

A. Schizophrenia itself does not typically affect thyroid diagnostic test results. However, some medications used to treat schizophrenia may potentially influence thyroid function, but the diagnosis alone is not a direct factor.
B. Oral contraceptives can affect thyroid function tests. They may increase the levels of thyroid-binding globulin (TBG), which could result in falsely elevated total thyroid hormone levels. This can affect the interpretation of thyroid function tests, such as TSH, T3, and T4.
C. Vitamin C does not typically interfere with thyroid function tests. It is generally considered safe and does not directly affect the results of thyroid diagnostic tests.
D. Obesity does not directly interfere with thyroid diagnostic tests. However, thyroid disorders, especially hypothyroidism, are more common in individuals with obesity, so it may be a consideration in assessing thyroid function.

Correct Answer is C

Explanation

A. Low serum thyroxine (T4) level In hyperthyroidism, the serum thyroxine (T4) level is typically elevated due to excessive production of thyroid hormones.
B. Decreased serum thyroid stimulating hormone (TSH) In hyperthyroidism, the body produces excess thyroid hormones (T3 and T4), which negatively feedback to the pituitary gland and result in decreased TSH levels. This is a key diagnostic finding.
C. Tachycardia or fine hand tremor Hyperthyroidism often causes symptoms like tachycardia (increased heart rate) and a fine hand tremor due to the overstimulation of the body's metabolism and sympathetic nervous system.
D. Elevated serum thyroid stimulating hormone (TSH) In hyperthyroidism, the TSH level is typically low due to negative feedback from the excess thyroid hormones.
E. Elevated serum thyroxine (T4) In hyperthyroidism, the serum thyroxine (T4) level is elevated because the thyroid gland is producing too much thyroid hormone.

Correct Answer is ["0.5"]

Explanation

First, determine how many milligrams are in 1 mL. We can do this by dividing the total milligrams by the total milliliters: 24 mg ÷ 2 mL = 12 mg/mL

Now we know that each milliliter of the solution contains 12 mg of sumatriptan.

To find the volume needed for a 6 mg dose, we need to figure out how many times 12 mg goes into 6 mg: 6 mg ÷ 12 mg/mL = 0.5 mL
