A client is seen in a primary care provider's office. The client has gradually developed a stooped posture, shuffling gait, and a lack of facial expressions. Which medication should the nurse anticipate will be prescribed to treat these symptoms?
Edrophonium
Prednisone
Carbidopa-levodopa
Riluzole
The Correct Answer is C
A. Edrophonium is used to diagnose myasthenia gravis, a neuromuscular disorder that causes muscle weakness. It is not used to treat the symptoms described in the question.
B. Prednisone is a corticosteroid used to treat various conditions, including autoimmune diseases and allergies. It is not used to treat Parkinson's disease, which is the most likely diagnosis based on the symptoms described.
C. This medication is the gold standard for treating Parkinson's disease, a neurodegenerative disorder that causes tremors, rigidity, bradykinesia (slowed movements), and postural instability. Carbidopa- levodopa helps to increase dopamine levels in the brain, which can improve motor function and reduce symptoms.
D. Riluzole is used to treat amyotrophic lateral sclerosis (ALS), a neurodegenerative disease that affects motor neurons. It is not used to treat Parkinson's disease.

Correct Answer is C
Explanation
A. Secondary hypothyroidism is characterized by insufficient production of thyroid hormones (T3 and T4) due to inadequate stimulation from the pituitary gland, not due to overproduction. Overproduction of thyroid hormones would typically be associated with hyperthyroidism, not hypothyroidism.
B. Adrenocorticotropic hormone (ACTH) stimulates the adrenal glands to produce cortisol. A deficiency in ACTH would lead to adrenal insufficiency or Addison's disease, not secondary hypothyroidism.
Secondary hypothyroidism specifically involves a deficiency in thyroid-stimulating hormone (TSH), not ACTH.
C. Secondary hypothyroidism is caused by inadequate production of thyroid-stimulating hormone (TSH) by the pituitary gland. TSH is necessary for stimulating the thyroid gland to produce thyroid hormones (T3 and T4). When the pituitary gland does not produce enough TSH, the thyroid gland is not adequately stimulated, leading to low levels of thyroid hormones in the blood.
D. Aldosterone is a hormone produced by the adrenal glands that helps regulate sodium and potassium levels, as well as blood pressure. A deficiency in aldosterone is associated with conditions such as
Addison’s disease or primary adrenal insufficiency, not secondary hypothyroidism. Secondary
hypothyroidism specifically relates to issues with TSH production, not aldosterone.
Correct Answer is ["0.4"]
Explanation
Volume to administer = (Desired Dose) / (Concentration of available medication). The desired dose is 2,000 units, and the concentration available is 5,000 units/mL. Using the formula, you get 2,000 units / 5,000 units/mL = 0.4 mL.
Therefore, the nurse should administer 0.4 mL of heparin injection to deliver a dose of 2,000 units.
