A nurse in a clinic is reviewing the laboratory values of a client who has primary hypothyroidism. The nurse should anticipate an elevation of which of the following laboratory values?

Free T4

Thyroid stimulating hormone (TSH)

Serum T3

Serum T4

Answer and Explanation

The Correct Answer is B

Choice A reason:
In primary hypothyroidism, the thyroid gland is underactive and does not produce sufficient thyroid hormones, including Free T4. Therefore, we would not expect an elevation of Free T4 in primary hypothyroidism; instead, its levels would typically be low or normal.

Choice B reason:
Thyroid stimulating hormone (TSH) levels are elevated in primary hypothyroidism because the pituitary gland releases more TSH in an attempt to stimulate the thyroid gland to produce more thyroid hormones. This is a compensatory response to the low levels of circulating thyroid hormones, particularly thyroxine (T4).

Choice C reason:
Serum T3 levels may be low or normal in primary hypothyroidism. T3 is the active form of thyroid hormone and is usually converted from T4. If T4 levels are low, T3 levels may also be affected; however, T3 levels are not the primary diagnostic marker for hypothyroidism and do not typically show elevation in this condition.

Choice D reason:
Serum T4 levels are typically low in primary hypothyroidism because the thyroid gland is not producing enough of this hormone. An elevation of serum T4 would not be expected unless the patient is receiving treatment for hypothyroidism.

Correct Answer is D

Explanation

Choice A reason:
While gargling with warm saline can provide symptomatic relief for a sore throat, it does not address the underlying bacterial infection. Therefore, it is not the priority action once a diagnosis of group A streptococcus has been confirmed.

Choice B reason:
Identifying close contacts is important for public health tracking and potentially preventing the spread of the infection. However, the immediate priority for the client is the initiation of treatment to address the infection.

Choice C reason:
Taking antipyretics can help manage fever and provide comfort to the client. While managing symptoms is important, it is secondary to initiating antibiotic therapy, which addresses the cause of the symptoms.

Choice D reason:
The priority action is to notify the client to return to the clinic for initiation of antibiotic therapy. Group A streptococcus is a bacterial infection that requires antibiotics for treatment. Prompt initiation of antibiotics is crucial to prevent complications and promote recovery.

A. Clay-colored stools B. Nystagmus C. Tinnitus D. Respiratory depression

Correct Answer is C

Explanation

Choice A reason:
Clay-colored stools are typically associated with issues in the biliary system, such as bile duct obstruction, and not directly with aspirin use. Aspirin, especially when used in high doses, is more commonly associated with gastrointestinal side effects like bleeding, which would likely cause dark or bloody stools rather than clay-colored ones.

Choice B reason:
Nystagmus, which is a vision condition characterized by repetitive, uncontrolled eye movements, is not a recognized side effect of aspirin. While aspirin can have effects on various systems in the body, it does not typically affect the muscles or nerves controlling eye movements.

Choice C reason:
Tinnitus, or ringing in the ears, is a well-documented adverse effect of aspirin, particularly when taken in high doses or for a prolonged period. It is related to the effect of aspirin on the inner ear structures and is usually reversible once the medication is stopped or the dosage is reduced.

Choice D reason:
Respiratory depression is not a typical side effect of aspirin. Aspirin can cause respiratory alkalosis in cases of overdose due to hyperventilation, but it does not cause respiratory depression. If respiratory depression occurs, it would likely be due to a different cause and not the aspirin itself.
