Nursing Elites

1. A secondary immune response differs from the primary immune response in that:

• A. It is more rapid than the primary response and results in higher antibody levels
• B. It is slower than the primary response and doesn't change the antibody levels
• C. It occurs at the same time as the primary response but results in a decrease in antibodies
• D. It only occurs in hyperallergic reactions and results in a decrease in antibodies

Correct answer: A

Rationale: The correct answer is A. A secondary immune response is characterized by being more rapid than the primary response and results in higher antibody levels. This is because memory B cells are already present and can quickly differentiate into plasma cells upon re-exposure to the antigen. Choice B is incorrect because a secondary immune response is faster, not slower, than the primary response, and it does lead to higher antibody levels. Choice C is incorrect because a secondary response does not result in a decrease in antibodies; instead, it leads to an increase. Choice D is incorrect because a secondary immune response is not limited to hyperallergic reactions, and it results in an increase, not a decrease, in antibodies.

2. A patient with a history of cardiovascular disease is being prescribed hormone replacement therapy (HRT). What should the nurse include in the patient education regarding the risks associated with HRT?

• A. HRT may increase the risk of cardiovascular events, including heart attack and stroke.
• B. HRT may decrease the risk of osteoporosis.
• C. HRT may increase the risk of venous thromboembolism.
• D. HRT may decrease the risk of breast cancer.

Correct answer: A

Rationale: The correct answer is A. Hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, including heart attack and stroke, especially in patients with a history of cardiovascular disease. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; in fact, it may increase the risk of certain conditions like venous thromboembolism, as mentioned in choice C. Choice D is also incorrect as HRT has been associated with a slight increase in the risk of breast cancer.

3. 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.

4. When taking medroxyprogesterone acetate (Provera) for the treatment of endometriosis, what important instruction should the nurse provide about taking this medication?

• A. Take the medication at the same time each day to maintain consistent hormone levels.
• B. Medroxyprogesterone should be taken without regard to meals.
• C. Discontinuing medroxyprogesterone should only be done under the guidance of a healthcare provider.
• D. Medroxyprogesterone is typically taken daily rather than weekly for the treatment of endometriosis.

Correct answer: A

Rationale: When taking medroxyprogesterone acetate for endometriosis, it is essential to maintain consistent hormone levels by taking the medication at the same time each day. This consistency helps optimize the effectiveness of the treatment. Choice B is incorrect because medroxyprogesterone should be taken without regard to meals, not necessarily with food. Choice C is incorrect because discontinuing the medication without consulting a healthcare provider can be harmful and may not address side effects appropriately. Choice D is incorrect as medroxyprogesterone is typically taken daily to manage endometriosis symptoms, not weekly, to ensure continuous therapy and symptom control.

5. While planning care for an elderly patient, the nurse remembers that increased age is associated with:

• A. Increased T cell function
• B. Increased immune function
• C. Increased production of antibodies
• D. Increased levels of circulating autoantibodies

Correct answer: D

Rationale: As individuals age, their immune function tends to decrease, making them more susceptible to infections and diseases. Additionally, increased age is associated with higher levels of circulating autoantibodies, which can lead to autoimmune conditions. Choice A is incorrect as aging is not typically associated with increased T cell function. Choice C is also incorrect as aging does not necessarily result in increased production of antibodies. Therefore, the correct answers are B (Decreased immune function) and D (Increased levels of circulating autoantibodies).
