Nursing Elites

1. In osteoporosis, what is the expected therapeutic action of raloxifene (Evista)?

• A. It decreases bone resorption and increases bone density.
• B. It stimulates the formation of new bone.
• C. It increases calcium absorption in the intestines.
• D. It decreases the excretion of calcium through the kidneys.

Correct answer: A

Rationale: The correct answer is A. Raloxifene works by decreasing bone resorption and increasing bone density. This helps in strengthening bones, reducing the risk of fractures, and improving bone health in patients with osteoporosis. Choice B is incorrect because raloxifene does not directly stimulate the formation of new bone but rather prevents bone loss. Choice C is incorrect as raloxifene does not primarily affect calcium absorption in the intestines. Choice D is also incorrect as raloxifene does not primarily decrease the excretion of calcium through the kidneys.

2. 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.

3. A 30-year-old man has a history of heart transplant and is receiving long-term steroids to prevent rejection. The patient is due for routine vaccines. Attenuated vaccines are contraindicated in this patient because the antigen is:

• A. live and can cause infection.
• B. mutated and infectious.
• C. inactive but still infectious
• D. pathogenic

Correct answer: A

Rationale: The correct answer is A: live and can cause infection. Patients who are immunocompromised, like those receiving long-term steroids after an organ transplant, should not receive live vaccines because the live attenuated organisms in these vaccines can cause infections in individuals with weakened immune systems. Choice B is incorrect because attenuated vaccines are live but weakened, not mutated. Choice C is incorrect because while inactive, attenuated vaccines are not infectious. Choice D is incorrect because attenuated vaccines are not pathogenic; they are attenuated (weakened) forms of the pathogen.

4. A 70-year-old man has enjoyed good overall health for all of his adult life, but he has been experiencing urinary frequency and dribbling that has culminated in a diagnosis of benign prostatic hypertrophy (BPH). As a result, the patient has been prescribed finasteride (Proscar). When teaching the patient about the potential adverse effects of the drug, the nurse should ensure that he knows about the possibility of

• A. sexual dysfunction.
• B. urethral burning.
• C. kidney stones.
• D. visual disturbances.

Correct answer: A

Rationale: The correct potential adverse effect of finasteride (Proscar) that the nurse should educate the patient about is sexual dysfunction. Finasteride is known to cause sexual side effects such as decreased libido, erectile dysfunction, and ejaculation disorders. Urethral burning, kidney stones, and visual disturbances are not commonly associated with finasteride use, making them incorrect choices for this scenario.

5. A 21-year-old male is brought to the ED following a night of partying in his fraternity. His friends found him 'asleep' and couldn't get him to respond. They cannot recall how many alcoholic beverages he drank the night before. While educating a student nurse and the man's friends, the nurse begins by explaining that alcohol is:

• A. A water-soluble compound that is easily absorbed by the gastric lining of the stomach.
• B. Very lipid-soluble and rapidly crosses the blood–brain barrier.
• C. Able to reverse the transport of some substances to remove them from the brain.
• D. Very likely to cause sedation and therefore the client just needs to sleep it off.

Correct answer: B

Rationale: The correct answer is B. Alcohol is very lipid-soluble and rapidly crosses the blood–brain barrier, leading to its effects on the central nervous system and causing symptoms like sedation and unconsciousness. Choice A is incorrect because alcohol is not water-soluble; it is lipid-soluble. Choice C is incorrect as alcohol does not reverse the transport of substances from the brain. Choice D is incorrect as sedation from alcohol is not a reason to just 'sleep it off' in cases of alcohol poisoning, which can be life-threatening and requires medical attention.
