The nurse is working with a client who is newly diagnosed with hypothyroidism. Diagnostic testing has indicated that the client’s health problem is caused by anterior pituitary dysfunction.
This client’s hypothyroidism is rooted in a deficiency of:
tetraiodothyronine.
thyroid-stimulating hormone (TSH).
triiodothyronine.
The Correct Answer is B
Choice A is wrong because tetraiodothyronine is another name for thyroxine (T), which is a hormone produced by the thyroid gland, not the anterior pituitary gland.14
Choice C is wrong because triiodothyronine (T) is also a hormone produced by the thyroid gland, not the anterior pituitary gland.14
Normal ranges for TSH are 0.4 to 4.0 mIU/L, for T are 100 to 200 ng/dL, and for T are 4.5 to 11.2 mcg/dL.1

Correct Answer is A
Explanation
Prednisone is a glucocorticoid that suppresses the production of natural cortisol by the adrenal glands. Taking prednisone on alternate days allows the adrenal glands to recover and produce some cortisol on the days without prednisone.
Choice B is wrong because prednisone does not eliminate adverse side effects, but may cause some such as weight gain, fluid retention, increased blood pressure, increased blood glucose, and increased risk of infection.
Choice C is wrong because there is no evidence of steroid tolerance, which means that higher doses are needed to achieve the same effect.
Choice D is wrong because prednisone does not prolong therapeutic effects, but may decrease them over time due to feedback inhibition of cortisol secretion.
Normal ranges for cortisol are 6 to 23 mcg/dL in the morning and 2 to 11 mcg/dL in the afternoon.
Correct Answer is D
Explanation
Glargine is a long-acting insulin that can provide a steady level of insulin for up to 24 hours. This would be suitable for a client who does not want to administer insulin on the plane, as they would only need one injection per day.
Choice A. Aspart is wrong because aspart is a rapid-acting insulin that has a peak effect within 1 to 3 hours and lasts for 3 to 5 hours.
This would require frequent injections and monitoring of blood glucose levels.
Choice B. Lispro is wrong because lispro is also a rapid-acting insulin that has a similar onset and duration as aspart.
It would not provide adequate coverage for a long international flight.
Choice C. Glulisine is wrong because glulisine is another rapid-acting insulin that has an onset of 15 minutes and a duration of 2 to 4 hours.
It would also require multiple injections and frequent blood glucose checks.
Normal ranges for blood glucose levels are 70 to 130 mg/dL before meals and less than 180 mg/dL after meals.
