The physician orders a Lidocaine drip to infuse at 2 mg/min. The drug is available as 2 gm in 500 ml of fluid. Solve for ml/hr.

Answer and Explanation

The Correct Answer is ["3"]

Lidocaine infusion calculation:

Lidocaine dose ordered: 2 mg/min
Lidocaine concentration: 2 gm in 500 mL
Conversion factor: 1 mg = 1000 mcg

Calculations:

Convert Lidocaine dose to mcg/min: 2 mg/min × 1000 mcg/mg = 2000 mcg/min
Lidocaine concentration is 2 gm in 500 mL, which equals 4000 mcg/mL.
Calculate mL/hr:
- mL/hr = (2000 mcg/min × 60 min/hr) / 4000 mcg/mL = 3 mL/hr

Answer:

mL/hr: 3 mL/hr

Correct Answer is A

Explanation

A. "You will need to use a bathroom separate from other household members." This prevents others from exposure to radioiodine through bodily fluids. Radioiodine is excreted primarily through urine and to a lesser extent through saliva and sweat, necessitating separate bathroom use to minimize radiation exposure to others.

B. "You will need to remain at the hospital for the entire time the radioiodine is radioactive." Most RAI treatments for hyperthyroidism are done on an outpatient basis.

C. "A low fiber diet will be necessary." Unrelated to radioiodine treatment. There is no specific dietary restriction related to fiber for RAI treatment.

D. "Additional Immunizations will be needed for full protection." Not relevant to radioiodine treatment. Radioiodine treatment does not require additional immunizations.

A. A 45-year-old female who has a family history of autoimmune disorders B. A 73-year-old male who has an iodine deficiency C. A 25-year-old female who has metabolic syndrome D. A 35-year-old male who has Graves' disease

Correct Answer is D

Explanation

A. A 45-year-old female who has a family history of autoimmune disorders. Autoimmune disorders can increase the risk of some thyroid conditions, but not necessarily hyperthyroidism.

B. A 73-year-old male who has an iodine deficiency: Iodine deficiency can lead to goiter and hypothyroidism but is not a common cause of hyperthyroidism.

C. A 25-year-old female who has metabolic syndrome: Metabolic syndrome is not directly linked to thyroid dysfunction.

D. A 35-year-old male who has Graves' disease: Graves’ disease is an autoimmune disorder that leads to overproduction of thyroid hormones, resulting in hyperthyroidism..
