Nursing Elites

1. A female patient has been diagnosed with tuberculosis and begun multiple-drug therapy. The woman has asked the nurse why it is necessary for her to take several different drugs instead of one single drug. How should the nurse best respond to the patient's question?

• A. “Multiple drugs are used because doctors need to combat the TB bacteria from different angles to effectively treat the infection.”
• B. “The use of multiple drugs prevents the development of drug-resistant TB.”
• C. “Multiple drugs are prescribed because the final testing results for TB can take up to 3 weeks to confirm the most effective treatment.”
• D. “Multiple drugs are used in order to speed up the course of treatment.”

Correct answer: B

Rationale: The correct answer is B. Using multiple drugs in tuberculosis treatment helps prevent the development of drug-resistant TB. This approach is crucial because if the infection is not completely eradicated, the remaining bacteria may become resistant to the single drug used, making future treatments less effective. Choice A is incorrect because the use of multiple drugs is not due to uncertainty about which drug will work, but rather to address the bacteria from different angles. Choice C is incorrect as it misleads the patient about the reason for using multiple drugs. Choice D is also incorrect because the primary purpose of using multiple drugs is not to speed up treatment but to ensure effectiveness and prevent resistance.

2. Which of the following best describes Cushing’s syndrome?

• A. Hypersecretion of growth hormone
• B. Excessive production of cortisol by the adrenal glands
• C. Insufficient production of insulin
• D. Increased levels of ACTH

Correct answer: B

Rationale: Cushing’s syndrome is characterized by the excessive production of cortisol by the adrenal glands, not growth hormone (Choice A), insulin (Choice C), or ACTH (Choice D). The increased cortisol levels lead to a variety of symptoms associated with Cushing’s syndrome.

3. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?

• A. History of peptic ulcer disease
• B. Use of nitrates
• C. Use of antihypertensive medications
• D. History of hypertension

Correct answer: B

Rationale: The correct answer is B: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates combined with sildenafil can lead to a dangerous drop in blood pressure. Choices A, C, and D are incorrect because a history of peptic ulcer disease, use of antihypertensive medications, or a history of hypertension are not direct contraindications for sildenafil use.

4. Which of the following hormones helps to raise the blood sugar level to help maintain homeostasis?

• A. Antidiuretic hormone (ADH)
• B. Insulin
• C. Glucagon
• D. Thyroxine

Correct answer: C

Rationale: The correct answer is C, Glucagon. Glucagon helps raise blood sugar levels by stimulating the liver to release stored glucose into the bloodstream, thus aiding in maintaining homeostasis. Antidiuretic hormone (ADH), choice A, functions in regulating water balance in the body, not blood sugar levels. Insulin, choice B, lowers blood sugar levels by facilitating glucose uptake by cells. Thyroxine, choice D, is a hormone produced by the thyroid gland that regulates metabolism and has no direct effect on blood sugar levels.

5. An 8-year-old boy has been diagnosed with a sex hormone deficiency and has begun a course of treatment with testosterone. What change in the boy's health status would necessitate a stop to the course of treatment?

• A. Excessive growth in height
• B. Signs of puberty
• C. Recurrent urinary tract infections
• D. Increased blood pressure

Correct answer: B

Rationale: In an 8-year-old boy with a sex hormone deficiency being treated with testosterone, the appearance of signs of puberty would necessitate stopping the treatment. Testosterone therapy in this case aims to supplement the deficient sex hormones but should not trigger premature puberty. Excessive growth in height (choice A) is not a typical reason to stop testosterone therapy. Recurrent urinary tract infections (choice C) and increased blood pressure (choice D) are not directly related to testosterone therapy in this context.
