Nursing Elites

1. A client asks a nurse about the cause of Parkinson's disease. How should the nurse respond?

• A. Parkinson's disease is caused by a lack of dopamine in the brain, which affects movement.
• B. Parkinson's disease is caused by an excess of acetylcholine in the brain, leading to tremors and rigidity.
• C. Parkinson's disease is caused by an autoimmune response that attacks the nervous system.
• D. Parkinson's disease is caused by a bacterial infection that needs to be treated with antibiotics.

Correct answer: A

Rationale: The correct answer is A. Parkinson's disease is caused by a deficiency of dopamine in the brain, which results in the characteristic motor symptoms such as tremors, rigidity, and bradykinesia. Choice B is incorrect because Parkinson's disease is not caused by an excess of acetylcholine. Choice C is incorrect because Parkinson's disease is not an autoimmune disorder. Choice D is incorrect because Parkinson's disease is not caused by a bacterial infection and cannot be treated with antibiotics.

2. What condition can be caused by an excessive amount of growth hormone released by the pituitary gland in childhood?

• A. Acromegaly
• B. Gigantism
• C. Syndrome of inappropriate antidiuretic hormone
• D. Dwarfism

Correct answer: B

Rationale: Gigantism is the correct answer. It is a condition caused by excessive growth hormone release before the epiphyseal plates close, leading to abnormal growth. Acromegaly (choice A) is caused by excess growth hormone after the epiphyseal plates close, resulting in enlargement of bones and tissues. Syndrome of inappropriate antidiuretic hormone (choice C) is characterized by the excessive release of antidiuretic hormone, leading to water retention and dilutional hyponatremia. Dwarfism (choice D) is a condition characterized by significantly below-average height.

3. What important point should the nurse emphasize about taking oral contraceptives consistently?

• A. Oral contraceptives must be taken at the same time each day to maintain consistent hormone levels and ensure effectiveness in preventing pregnancy.
• B. Oral contraceptives should be taken in the morning to avoid side effects at night.
• C. Oral contraceptives should be taken with food to enhance absorption.
• D. Oral contraceptives can be skipped occasionally without significant consequences.

Correct answer: A

Rationale: The correct answer is A. It is crucial for patients taking oral contraceptives to take them at the same time each day to maintain consistent hormone levels, which is essential for their effectiveness in preventing pregnancy. Choice B is incorrect as the timing of the medication is more about consistency than avoiding side effects at night. Choice C is incorrect as oral contraceptives do not necessarily need to be taken with food for absorption. Choice D is incorrect because skipping oral contraceptives occasionally can significantly reduce their effectiveness in preventing pregnancy.

4. After teaching the students about B cells, which statement indicates teaching was successful? B cells are originally derived from cells of the:

• A. Bone marrow
• B. Lymph nodes
• C. Gut-associated lymphoid tissue
• D. Thymus

Correct answer: A

Rationale: The correct answer is A: Bone marrow. B cells are originally derived from cells of the bone marrow. Bone marrow is the primary site where B cells develop and mature. Lymph nodes (choice B), gut-associated lymphoid tissue (choice C), and the thymus (choice D) are involved in the immune response but are not the primary site of origin for B cells.

5. A patient is prescribed levothyroxine (Synthroid) for hypothyroidism. What is a key point the nurse should include in the patient education?

• A. Take the medication on an empty stomach with a full glass of water to ensure proper absorption.
• B. Do not take this medication with calcium supplements.
• C. Avoid taking this medication with grapefruit juice.
• D. Take the medication with food to enhance absorption.

Correct answer: A

Rationale: The correct answer is A. Levothyroxine should be taken on an empty stomach with a full glass of water, typically 30 minutes to an hour before breakfast, to ensure proper absorption. Taking it with food, calcium supplements, or grapefruit juice can interfere with its absorption. Choice B is incorrect because taking levothyroxine with calcium supplements can reduce its effectiveness. Choice C is incorrect because grapefruit juice can also interfere with levothyroxine absorption. Choice D is incorrect because taking levothyroxine with food can decrease its absorption.
