The nurse is assessing a client newly diagnosed with hyperthyroidism. The nurse should expect which of the following?

Low serum thyroxine (T4) level

Decreased serum thyroid stimulating hormone (TSH)

Tachycardia or fine hand tremor

Elevated serum thyroid stimulating hormone (TSH)

Elevated serum thyroxine (T4)

Answer and Explanation

The Correct Answer is C

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 B

Explanation

A. Regular insulin IV at 0.1 unit/kg/hr is a standard prescription for managing diabetic ketoacidosis (DKA). Regular insulin is administered intravenously to reduce blood glucose and correct the acidosis in DKA.
B. The nurse should clarify this prescription. In the initial management of DKA, the focus is on correcting fluid deficits, and a typical intravenous fluid for this purpose is 0.9% normal saline (not dextrose). Once blood glucose levels start to decrease and are near 200 mg/dL, dextrose may be introduced to prevent hypoglycemia, but it should not be started too early in the treatment of DKA.
C. Monitoring arterial blood gases (ABGs) is crucial in DKA to assess the severity of acidosis and monitor the effectiveness of treatment, typically done every 1 to 2 hours.
D. Regular insulin is typically mixed with 0.9% normal saline for intravenous administration in DKA. This solution helps deliver the insulin slowly and safely while rehydrating the client.

A. warfarin (Coumadin) B. pantoprazole (Protonix) C. metformin (Glucophage) D. fluoxetine (Prozac)

Correct Answer is C

Explanation

A. While warfarin is an anticoagulant, it is not contraindicated with contrast imaging. However, the nurse should monitor for bleeding and report any abnormal findings, but this medication is not a priority to report immediately in the context of a CT scan.
B. Pantoprazole is a proton pump inhibitor used to treat acid reflux, and it does not pose any specific concerns regarding the administration of contrast for an abdominal CT scan.
C. Metformin should be reported immediately. It is contraindicated in clients undergoing contrast procedures because it can increase the risk of lactic acidosis, particularly in those with renal impairment. Metformin should generally be withheld 48 hours before and after receiving contrast material to avoid this risk.
D. Fluoxetine is an antidepressant (SSRI) and does not have a direct interaction with the contrast medium used in CT scans. It is not a priority to report in this situation.
