Nursing Elites

1. Which of the following disorders is more likely to be associated with blood in the stool?

• A. Gastroesophageal reflux
• B. Crohn's disease
• C. Irritable bowel syndrome
• D. Colon cancer

Correct answer: D

Rationale: The correct answer is D, Colon cancer. Colon cancer commonly presents with blood in the stool due to bleeding from the tumor. Gastroesophageal reflux (Choice A) is associated with heartburn and regurgitation of stomach contents into the esophagus. Crohn's disease (Choice B) is a type of inflammatory bowel disease that can cause symptoms like abdominal pain, diarrhea, and weight loss, but it does not typically present with blood in the stool as a primary symptom. Irritable bowel syndrome (Choice C) is a functional gastrointestinal disorder characterized by symptoms such as abdominal pain, bloating, and changes in bowel habits, but it does not usually involve blood in the stool as a prominent feature.

2. A patient is starting on atorvastatin (Lipitor) for hyperlipidemia. What critical instruction should the nurse provide?

• A. Take the medication at night to reduce the risk of muscle pain and other side effects.
• B. Avoid consuming grapefruit juice while taking this medication.
• C. Take the medication in the morning with breakfast to improve absorption.
• D. Take the medication with a high-fat meal to increase its effectiveness.

Correct answer: A

Rationale: The correct answer is to take the medication at night to reduce the risk of muscle pain and other side effects. Atorvastatin, like other statins, is more effective when taken in the evening as the body produces more cholesterol at night. Taking it with a high-fat meal (choice D) is not recommended as it may reduce the drug's absorption. Grapefruit juice (choice B) should be avoided with atorvastatin as it can increase the risk of side effects. Taking the medication in the morning with breakfast (choice C) is not as effective as taking it at night.

3. A patient is starting on alendronate (Fosamax) for osteoporosis. What instructions should the nurse provide to ensure the effectiveness of the medication?

• A. Take the medication with a full glass of water and remain upright for at least 30 minutes.
• B. Take the medication at bedtime to ensure absorption during sleep.
• C. Take the medication with milk to enhance calcium absorption.
• D. Take the medication with food to prevent gastrointestinal upset.

Correct answer: A

Rationale: The correct answer is to take alendronate with a full glass of water and remain upright for at least 30 minutes. This is essential to prevent esophageal irritation and ensure proper absorption. Choice B is incorrect because taking alendronate at bedtime can increase the risk of esophageal irritation due to lying down. Choice C is incorrect as taking alendronate with milk can reduce its absorption. Choice D is incorrect because alendronate should be taken on an empty stomach to enhance its effectiveness.

4. When arterial blood pressure declines, the kidneys secrete a hormone to increase blood pressure and peripheral resistance. What is this hormone called?

• A. Renin
• B. Antidiuretic hormone
• C. Atrial natriuretic
• D. Insulin

Correct answer: A

Rationale: Renin is the correct answer. When arterial blood pressure decreases, the kidneys release renin, which triggers a series of reactions ultimately leading to an increase in blood pressure and peripheral resistance. Antidiuretic hormone (choice B) is involved in water retention, atrial natriuretic hormone (choice C) promotes sodium excretion and lowers blood pressure, and insulin (choice D) regulates glucose metabolism, not blood pressure.

5. A male patient is receiving testosterone therapy for hypogonadism. What serious adverse effect should the nurse monitor for during this therapy?

• A. Increased risk of liver dysfunction
• B. Increased risk of prostate cancer
• C. Increased risk of bone fractures
• D. Increased risk of breast cancer

Correct answer: A

Rationale: The correct answer is A: Increased risk of liver dysfunction. Testosterone therapy can lead to liver dysfunction, including cholestatic jaundice and hepatitis. This adverse effect necessitates monitoring of liver function tests during testosterone therapy. Choice B, increased risk of prostate cancer, is incorrect because testosterone therapy does not cause prostate cancer but is contraindicated in patients with known or suspected prostate cancer. Choice C, increased risk of bone fractures, is incorrect as testosterone therapy is actually associated with an increase in bone mineral density, reducing the risk of fractures. Choice D, increased risk of breast cancer, is incorrect because testosterone therapy in males does not increase the risk of breast cancer.
