Question 1 of 5
The effectiveness of Levodopa can be reduced when taking:
Correct Answer: A
Rationale: The correct choice is Pyridoxine. Levodopa is a precursor to dopamine and is commonly used in the treatment of Parkinson's disease. Pyridoxine, also known as vitamin B6, has been shown to reduce the effectiveness of Levodopa by accelerating its conversion to dopamine in the bloodstream before it reaches the brain. This reduces the amount of Levodopa available to provide therapeutic benefit in Parkinson's disease. It is important for patients taking Levodopa to be cautious about taking vitamin B6 supplements to avoid diminishing the efficacy of their medication.
Question 2 of 5
A client with a history of hypertension is diagnosed with primary hyperaldosteronism. This diagnosis indicates that the client's hypertension is caused by excessive hormone secretion from which of the following glands?
Correct Answer: A
Rationale: Primary hyperaldosteronism is a condition characterized by excessive production of aldosterone by the adrenal cortex. Aldosterone is a hormone produced by the adrenal glands that plays a key role in regulating blood pressure and electrolyte balance in the body. When there is an overproduction of aldosterone, it can lead to increased sodium retention and potassium excretion, resulting in hypertension. Therefore, in this case, the client's hypertension is caused by excessive hormone secretion from the adrenal cortex, making option A the correct answer.
Question 3 of 5
The nurse teaches a client with newly diagnosed hypothyroidism about the need for thyroid hormone replacement therapy to restore normal thyroid function. Which thyroid preparation is the agent of choice for thyroid hormone replacement therapy?
Correct Answer: D
Rationale: Levothyroxine (Synthroid) is the agent of choice for thyroid hormone replacement therapy in clients with hypothyroidism. Levothyroxine is a synthetic form of the thyroid hormone T4 and is considered a stable and reliable medication for thyroid replacement. It is usually well tolerated and has a consistent potency, making it easier to adjust the dosage based on the client's thyroid hormone levels. Levothyroxine is typically taken orally once daily on an empty stomach, preferably in the morning, to ensure optimal absorption. In contrast, Methimazole (Tapazole) is used to treat hyperthyroidism by inhibiting the production of thyroid hormones, Livothyronine (Cytomel) is a synthetic form of the thyroid hormone T3, and Thyroid USP dessicated (Thyroid USP) is a natural preparation derived from porcine thyroid glands,
Question 4 of 5
25-year old Francisco M., is diagnosed as having myelocytic leukemia and is admitted for chemotherapy. Francisco M.'s laboratory results indicate bone marrow depression. The nurse should encourage him to:
Correct Answer: B
Rationale: The correct option is B - Use a soft toothbrush and electric razor. When a patient is diagnosed with myelocytic leukemia and has bone marrow depression as indicated by laboratory results, the platelet count is usually low which can lead to increased risk of bleeding. Therefore, it is important for the patient to use a soft toothbrush and electric razor to minimize the risk of injury and bleeding. Hard toothbrushes and sharp razors can cause damage to the gums and skin, leading to bleeding complications. It is essential to take precautions to prevent injury and promote safety for the patient undergoing chemotherapy with bone marrow depression.
Question 5 of 5
The following are known to be causes of hepatitis except:
Correct Answer: C
Rationale: Hepatitis is inflammation of the liver, and it can be caused by viruses, toxins, or chemicals and drugs. Bacteria, however, do not typically cause hepatitis. Common viral causes of hepatitis include hepatitis A, B, and C. Toxins like alcohol and certain medications, as well as exposure to chemicals, can also lead to hepatitis. Therefore, bacteria are not considered one of the primary causes of hepatitis.
