A nurse in a clinic is reviewing the laboratory values of a patient who has primary hypothyroidism. The nurse should anticipate an elevation in which of the following laboratory values?
Free T4.
Serum T3.
Thyroid stimulating hormone (TSH).
Serum calcium.
The Correct Answer is C
Choice A rationale
Free T4 levels are typically low in primary hypothyroidism, not elevated.
Choice B rationale
Serum T3 levels are also typically low in primary hypothyroidism.
Choice C rationale
In primary hypothyroidism, the thyroid gland is not producing enough thyroid hormone, leading to an elevated TSH level as the pituitary gland tries to stimulate more hormone production.
Choice D rationale
Serum calcium levels are not directly affected by primary hypothyroidism.

Correct Answer is D
Explanation
Choice A rationale
Monitoring for changes in the color of urine to maroon or red is not typically associated with peptic ulcers. This could be a sign of other conditions such as urinary tract infections, kidney stones, or certain medications.
Choice B rationale
Unintentional weight gain is not a common symptom of peptic ulcers. In fact, some people with peptic ulcers may experience weight loss due to discomfort while eating or a decrease in appetite.
Choice C rationale
The appearance of ecchymosis (bruising) on the sides of the abdomen or pelvic areas is not a typical symptom or concern with peptic ulcers. This could be a sign of trauma, certain medications, or other medical conditions.
Choice D rationale
One of the symptoms of a peptic ulcer can be changes in the color of the stool, particularly if it becomes dark or black. This can be a sign of bleeding in the gastrointestinal tract, which can occur with peptic ulcers. Therefore, patients should be advised to monitor for this symptom and seek medical attention if it occurs.

Vitamin D helps the body absorb calcium, but it is not specifically known to promote wound healing.
