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.”.

Answer and Explanation

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 A

Explanation

Levothyroxine is a synthetic form of thyroxine, the hormone that the thyroid gland normally produces.It is used to treat hypothyroidism by replacing the missing hormone and restoring the normal metabolism.

Some explanations for the other choices are:

• Choice B. Thyroid desiccated is a natural thyroid hormone derived from animal thyroid glands.

It contains both T4 and T3 hormones, which may cause side effects or complications in some people with hypothyroidism.It is not recommended as a first-line treatment for hypothyroidism.

• Choice C. Methimazole is an antithyroid drug that blocks the production of thyroid hormones.

It is used to treat hyperthyroidism, not hypothyroidism.Giving methimazole to someone with hypothyroidism would worsen their condition.

• Choice D. Liothyronine is a synthetic form of T3, the active thyroid hormone.

It is sometimes used in combination with levothyroxine to treat hypothyroidism, but it is not a standard treatment.It has a shorter half-life and more variable effects than levothyroxine, and it may increase the risk of cardiac arrhythmias or osteoporosis.

Normal ranges for thyroid function tests vary depending on the laboratory and the method used, but generally they are:

• TSH: 0.4 to 4.0 mIU/L

• Free T4: 0.8 to 2.0 ng/dL

• Free T3: 2.3 to 4.2 pg/mL

A. St. John’s wort. B. Alcohol. C. Calcium channel blockers. D. Selective serotonin reuptake inhibitors (SSRIs).

Correct Answer is B

Explanation

The nurse should caution the student to avoid using alcohol with trimethobenzamide because this combination can cause side effects such as drowsiness, dizziness, and impaired reactions. Alcohol can also worsen the symptoms of nausea and vomiting.

Choice A is wrong because St.

John’s wort is a herbal supplement that is used to treat depression and anxiety.

It does not interact with trimethobenzamide.

Choice C is wrong because calcium channel blockers are a class of medications that are used to treat high blood pressure and heart problems.

They do not interact with trimethobenzamide.

Choice D is wrong because selective serotonin reuptake inhibitors (SSRIs) are a class of medications that are used to treat depression and anxiety.

They do not interact with trimethobenzamide.

Trimethobenzamide is an antihistamine that works by blocking the D receptor in the brain and suppressing the chemoreceptor trigger zone that causes nausea and vomiting.

It is available as an oral capsule or an intramuscular injection.

It can cause side effects such as skin rash, tremors, parkinsonism, and jaundice.

It should not be used in children or people with liver or kidney disease.
