After administering propylthiouracil (PTU), what effect would the nurse anticipate the drug will have in the client’s body?
To suppress the hypothalamus’s production of thyrotropin-releasing hormone (TRH).
To suppress the anterior pituitary gland’s secretion of thyroid-stimulating hormone (TSH).
To inhibit production of thyroid hormone in the thyroid gland.
To destroy part of the thyroid gland.
The Correct Answer is C
Propylthiouracil (PTU) is an antithyroid drug that blocks the synthesis of thyroid hormones by interfering with the oxidation of iodine and the coupling of iodotyrosines.
This reduces the levels of triiodothyronine (T) and thyroxine (T) in the blood and relieves the symptoms of hyperthyroidism.
Choice A is wrong because PTU does not destroy any part of the thyroid gland.
It only inhibits the production of thyroid hormones within the gland.
Choice B is wrong because PTU does not suppress the anterior pituitary gland’s secretion of thyroid-stimulating hormone (TSH).
TSH is a hormone that stimulates the thyroid gland to produce thyroid hormones.
PTU does not affect the feedback loop between the hypothalamus, pituitary, and thyroid glands.
Choice D is wrong because PTU does not suppress the hypothalamus’s production of thyrotropin-releasing hormone (TRH).
TRH is a hormone that stimulates the pituitary gland to secrete TSH.
PTU does not affect the feedback loop between the hypothalamus, pituitary, and thyroid glands.
Normal ranges for T are 80 to 220 ng/dL, for T are 4.5 to 11.2 mcg/dL, and for TSH are 0.4 to 4.0 mIU/L.

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 can take it once a day at the same time.
Choice A. Glulisine is wrong because glulisine is a rapid-acting insulin that starts working within 15 minutes and lasts for 3 to 4 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 starts working within 15 minutes and lasts for 3 to 4 hours.
This would also require frequent injections and monitoring of blood glucose levels.
Choice C. Aspart is wrong because aspart is another rapid-acting insulin that starts working within 15 minutes and lasts for 3 to 4 hours.
This would also require frequent injections and monitoring of blood glucose levels.
Normal ranges for blood glucose levels are 70 to 130 mg/dL before meals and less than 180 mg/dL two hours after meals.
Correct Answer is C
Explanation
This statement indicates that the patient understands the common side effect of codeine and how to prevent accidents while taking it.
Choice A is wrong because the patient should not take the medication anytime he starts to cough, but only as prescribed by the doctor.
Taking too much codeine can lead to overdose, addiction, or respiratory depression.
Choice B is wrong because this medication may not make the patient anxious and nervous, but rather sedated and relaxed.
Anxiety and nervousness are more likely to occur with decongestants, which are stimulants.
Choice D is wrong because diarrhea is not a common side effect of codeine.
In fact, codeine may cause constipation, so the patient should increase fluid and fiber intake while taking it.
