A nurse in a clinic is reviewing the laboratory values of a client who has primary hypothyroidism.

Which of the following laboratory values should the nurse anticipate an elevation of?

Free T4

Serum T3

Serum T4

Thyroid stimulating hormone (TSH)

Answer and Explanation

The Correct Answer is D

A.   In primary hypothyroidism, the thyroid gland fails to produce sufficient thyroid hormone.
Consequently, free T4 levels are typically decreased.
B.   Although serum T3 levels may also decrease in primary hypothyroidism due to impaired thyroid function, TSH is the primary marker used for diagnosis and monitoring.
C.   Similarly, serum T4 levels may decrease in primary hypothyroidism due to decreased synthesis by the thyroid gland.
D.   In primary hypothyroidism, the anterior pituitary gland releases more TSH to stimulate the thyroid gland to produce thyroid hormones. Therefore, elevated TSH levels are characteristic of primary hypothyroidism.

Correct Answer is B

Explanation

A. The erythrocyte sedimentation rate (ESR) is a nonspecific marker of inflammation and is not used to assess the therapeutic effect of epoetin alfa.
B. The hematocrit (Hct) measures the proportion of red blood cells in the blood. Epoetin alfa stimulates the production of red blood cells, leading to an increase in hematocrit levels, indicating a therapeutic effect of the medication.
C. The leukocyte count measures the number of white blood cells in the blood and is not relevant for assessing the therapeutic effect of epoetin alfa.
D. The platelet count measures the number of platelets in the blood and is not relevant for assessing the therapeutic effect of epoetin alfa.

A. Wheezing B. Decreased deep tendon reflexes C. Cerebral edema D. Hypoactive bowel sounds

Correct Answer is B

Explanation

A. Wheezing is not typically associated with hyperkalemia. It can be seen in conditions such as asthma or chronic obstructive pulmonary disease (COPD).
B. Hyperkalemia can lead to neuromuscular manifestations, including decreased deep tendon reflexes due to suppression of neuromuscular excitability.
C. Cerebral edema is not a typical manifestation of hyperkalemia. It may occur in conditions such as hyponatremia or severe metabolic acidosis.
D. Gastrointestinal manifestations of hyperkalemia are typically related to smooth muscle involvement and can include hyperactive bowel sounds or diarrhea.
