The nurse admits to the clinic a 7-month-old infant whose parents report that the baby has not had a bowel movement in 4 days.
What is the nurse’s best action?

Administer a glycerin suppository as prescribed.

Administer magnesium hydroxide as prescribed.

Encourage watchful waiting for 24 hours.

Encourage feeding supplementation with free water.

Answer and Explanation

The Correct Answer is A

Glycerin suppositories are safe and effective for infants with constipation. They work by lubricating and softening the stool, and stimulating the rectal muscles to contract.

Choice B is wrong because magnesium hydroxide is not recommended for infants under 6 months of age, and may cause diarrhea, electrolyte imbalance, or magnesium toxicity.

Choice C is wrong because watchful waiting for 24 hours may not be enough to relieve the infant’s discomfort and may lead to further complications such as fecal impaction or dehydration.

Choice D is wrong because feeding supplementation with free water may not be sufficient to treat constipation, and may dilute the infant’s intake of nutrients and electrolytes.

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. Loratadine. B. Diphenhydramine. C. Hydroxyzine. D. Dexchlorpheniramine.

Correct Answer is A

Explanation

Loratadine is a second-generation antihistamine that does not cause drowsiness or sedation as a common side effect. It can relieve the symptoms of seasonal rhinitis such as sneezing, runny nose, and itching.

Choice B. Diphenhydramine is wrong because it is a first-generation antihistamine that can cause drowsiness or sedation as a common side effect.

It can also cause dry mouth, blurred vision, and urinary retention.

Choice C. Hydroxyzine is wrong because it is also a first-generation antihistamine that can cause drowsiness or sedation as a common side effect.

It can also cause dry mouth, blurred vision, and urinary retention.

It is mainly used for anxiety and itching.

Choice D. Dexchlorphen
