Nursing Elites

1. What causes type I diabetes?

• A. Overproduction of insulin from the beta cells of the pancreas
• B. Destruction of the beta cells within the pancreas, resulting in an inability to produce insulin
• C. Loss of insulin receptors on the target cells, resulting in insulin resistance
• D. A pituitary tumor in the brain, resulting in increased antidiuretic hormone production

Correct answer: B

Rationale: Type I diabetes is caused by the destruction of the beta cells in the pancreas, leading to an inability to produce insulin. This results in a lack of insulin, leading to hyperglycemia. Choice A is incorrect as type I diabetes is characterized by a deficiency of insulin production, not overproduction. Choice C describes the pathophysiology of type 2 diabetes, where insulin receptors become less responsive to insulin. Choice D is unrelated to type I diabetes as it describes a pituitary tumor causing increased antidiuretic hormone production.

2. A patient being treated for tuberculosis is determined to be drug resistant. Which of the following medications will the patient be resistant to in the treatment of tuberculosis?

• A. Isoniazid (INH) and rifampin
• B. Carbamazepine (Tegretol) and phenytoin (Dilantin)
• C. Dextroamphetamine (Dexedrine) and doxapram (Dopram)
• D. Propranolol (Inderal) and sotalol (Betapace)

Correct answer: A

Rationale: In the treatment of tuberculosis, drug resistance commonly develops against medications like Isoniazid (INH) and rifampin. These two drugs are key components of the standard anti-tuberculosis treatment regimen. Choices B, C, and D are unrelated medications that are not used in the treatment of tuberculosis. Carbamazepine and phenytoin are anticonvulsants, dextroamphetamine is a stimulant, and propranolol and sotalol are used for cardiovascular conditions.

3. After experiencing several months of worsening nocturia, a patient has been assessed for benign prostatic hypertrophy (BPH) and has begun drug treatment. In addition to nocturia, what other sign or symptom is most likely to accompany BPH?

• A. Hematuria
• B. Erectile dysfunction
• C. Urinary frequency
• D. Flank pain

Correct answer: A

Rationale: The correct answer is hematuria. Hematuria, which is the presence of blood in the urine, is a common sign associated with benign prostatic hypertrophy (BPH). It can occur due to irritation or damage to the prostate tissue. While urinary frequency and erectile dysfunction can also be seen in BPH patients, hematuria is more specifically linked to prostate issues. Flank pain is not typically a direct symptom of BPH.

4. A patient is prescribed medroxyprogesterone acetate (Provera) for endometriosis. What should the nurse teach the patient about the proper use of this medication?

• A. Take the medication at the same time each day to maintain consistent hormone levels.
• B. Avoid prolonged sun exposure while taking this medication.
• C. Discontinue the medication if side effects occur.
• D. Apply the medication once a week.

Correct answer: A

Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. Consistency in timing helps regulate the hormone levels in the body, ensuring the medication's optimal benefit. Choice B is incorrect as there is no specific need to avoid sun exposure with this medication. Choice C is incorrect because discontinuing the medication without consulting the healthcare provider may not be safe. Choice D is incorrect as medroxyprogesterone acetate is typically taken orally and not applied topically once a week.

5. Helicobacter pylori (H. pylori) often causes which of the following?

• A. Colon cancer
• B. Hiatal hernia
• C. Peptic ulcer disease
• D. Esophageal varices

Correct answer: C

Rationale: Helicobacter pylori is a bacterium known to cause peptic ulcer disease by weakening the protective lining of the stomach and duodenum, leading to inflammation and ulcers. While chronic H. pylori infection is a risk factor for stomach cancer, it is not directly linked to colon cancer (Choice A), hiatal hernia (Choice B), or esophageal varices (Choice D). Therefore, the correct answer is C.
