What statement by a client who is to take an antitussive with codeine indicates that the nurse’s teaching has been effective?
“I will take this medication anytime I start to cough.”.
“This medication may make me anxious and nervous.”.
“This medication can cause drowsiness, so I will avoid driving after taking it.”.
“I might get diarrhea, so I’ll call my provider if that happens.”.
The Correct Answer is C
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.

Correct Answer is C
Explanation
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 B
Explanation
This is because antiemetics should be given to prevent motion sickness rather than after nausea or vomiting develop. Taking the medication 30 minutes before departing allows enough time for the drug to be absorbed and reach its peak effect.
Choice A is wrong because avoiding eating or drinking for 6 hours before the trip may cause dehydration and low blood sugar, which can worsen nausea and vomiting.
It is better to eat a light meal or snack before the trip and avoid spicy, greasy, or acidic foods.
Choice C is wrong because taking two doses if relief is not achieved may cause overdose and adverse effects.
Antiemetics should be taken as prescribed and not exceeded without consulting a doctor.
Choice D is wrong because increasing fluid intake to prevent urinary retention is not relevant for motion sickness.
Urinary retention is a possible side effect of some antiemetics, such as anticholinergics, but it is not a common problem for most people.
Fluid intake should be moderate and not excessive to avoid stomach distension.
