Question 1 of 5
A patient is scheduled for an MRI and asks what to expect. Which of the following responses by the nurse is best?
Correct Answer: D
Rationale: The best response by the nurse in this scenario is option D: "It is a noninvasive test that uses magnetic energy to visualize internal parts." This response provides a clear and accurate description of what an MRI (Magnetic Resonance Imaging) involves. An MRI is a diagnostic test that uses a powerful magnetic field, radio waves, and a computer to create detailed images of the internal structures of the body. It is noninvasive, meaning there are no needles, electrodes, or injections involved. By explaining the procedure in a simple and understandable way, the nurse can help alleviate any anxiety or concerns the patient may have about the upcoming MRI.
Question 2 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 3 of 5
Which of the following terms would indicate to the nurse that a substance is toxic to the ear?
Correct Answer: B
Rationale: The term "ototoxic" indicates that a substance has the potential to cause damage to the ear or auditory system. Ototoxic substances can lead to hearing loss or damage to the inner ear structures. Therefore, if a nurse encounters the term ototoxic in a clinical setting, it would indicate that the substance being discussed is toxic to the ear. The other options, otoplasty, otalgia, and tinnitus, do not specifically indicate toxicity to the ear.
Question 4 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 5 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,
