When providing health education to a client taking octreotide, the nurse should warn the client about the possibility of what potential adverse effect?

Abdominal pain.

Tinnitus.

Alteration in consciousness.

Changes in vision.

Answer and Explanation

The Correct Answer is A

Octreotide is a synthetic analog of somatostatin, a hormone that inhibits the secretion of growth hormone, insulin, glucagon, and other hormones. Octreotide can cause gastrointestinal side effects such as abdominal pain, diarrhea, constipation, nausea, vomiting, and flatulence. These side effects are more common and severe with the oral route than with the injectable route.

Choice B is wrong because tinnitus, or ringing in the ears, is not a common or serious side effect of octreotide.

Choice C is wrong because alteration in consciousness is not a common or serious side effect of octreotide.

However, octreotide can affect blood glucose levels and cause hypoglycemia or hyperglycemia, which can lead to confusion, dizziness, fainting, seizures, or coma in severe cases.

Choice D is wrong because changes in vision are not a common or serious side effect of octreotide.

However, octreotide can cause rare but serious eye problems such as blurred vision, double vision, eye pain, or blindness due to optic nerve damage or retinal detachment.

These eye problems require immediate medical attention.

Normal ranges for blood glucose are 70 to 100 mg/dL (3.9 to 5.6 mmol/L) for fasting and less than 140 mg/dL (7.8 mmol/L) for postprandial.

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. Decrease theophylline dosage immediately. B. Decrease theophylline dose when normal thyroid function returns. C. Discontinue the client’s theophylline. D. Increase theophylline dosage immediately.

Correct Answer is B

Explanation

This is because hypothyroidism can reduce the metabolism and clearance of theophylline, leading to higher serum levels and increased risk of toxicity. Therefore, when the thyroid function is restored by levothyroxine or liothyronine, the dose of theophylline may need to be lowered to avoid excessive effects.

Choice A is wrong because decreasing theophylline dosage immediately may result in suboptimal control of asthma symptoms.

The dose adjustment should be based on serum theophylline levels and clinical response.

Choice C is wrong because discontinuing the client’s theophylline may cause worsening of asthma and potentially life-threatening complications.

Theophylline is an important bronchodilator that should not be stopped abruptly without medical supervision.

Choice D is wrong because increasing theophylline dosage immediately may cause overdose and adverse effects such as nausea, vomiting, headache, tachycardia, arrhythmias, seizures and even death.

The dose of theophylline should be carefully titrated according to serum levels and clinical response.
