Nursing Elites

1. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

2. Your patient has an order to receive Levothyroxine Sodium 75 mcg daily IV. You have a vial containing 100 mcg available from the pharmacy. According to the package insert, 5 mL of 0.9% sodium chloride is needed to reconstitute. You add the appropriate amount of sodium chloride to the vial. How many mcg of medication are in 1 mL of the vial?

• A. 20 mcg
• B. 15 mcg
• C. 25 mcg
• D. 30 mcg

Correct answer: A

Rationale: After reconstitution, the concentration of Levothyroxine Sodium in the vial is 100 mcg in 5 mL, which equals 20 mcg/mL. Therefore, in 1 mL of the vial, there are 20 mcg of medication.

3. A client with heart failure is prescribed furosemide (Lasix). Which instruction should the nurse include in the client's teaching plan?

• A. Take the medication before bedtime.
• B. Report any weight gain of more than 2 pounds in a day.
• C. Increase your intake of high-sodium foods.
• D. Limit your fluid intake to less than 1 liter per day.

Correct answer: B

Rationale: In heart failure, fluid retention is a concern. Furosemide helps manage this by promoting diuresis. Instructing the client to report weight gain exceeding 2 pounds in a day is crucial as it can indicate fluid accumulation, prompting timely intervention to prevent worsening heart failure symptoms and complications.

4. A client with portal hypertension who has developed ascites is scheduled for a paracentesis. What pre-procedure nursing intervention is essential?

• A. Encourage the client to empty the bladder
• B. Administer a laxative to clear the bowels
• C. Restrict the client's fluid intake
• D. Place the client in a supine position

Correct answer: A

Rationale: Emptying the bladder before a paracentesis is essential to prevent bladder injury during the procedure. A full bladder may be in the path of the needle insertion, increasing the risk of bladder puncture. Encouraging the client to empty the bladder ensures their safety and reduces the likelihood of complications.

5. A client with a history of hypertension is prescribed hydrochlorothiazide. Which instruction should the nurse include in the client's teaching?

• A. Take this medication in the morning.
• B. Avoid foods high in potassium.
• C. Monitor your blood pressure regularly.
• D. Decrease your intake of high-sodium foods.

Correct answer: C

Rationale: Regular monitoring of blood pressure is crucial for individuals with hypertension to assess the effectiveness of the prescribed medication and to ensure blood pressure is within the target range. This helps in managing hypertension and preventing complications associated with high blood pressure. Choices A, B, and D are incorrect because while taking the medication in the morning may be recommended for some drugs, it is not the key instruction for hydrochlorothiazide. Avoiding foods high in potassium and decreasing high-sodium foods are important dietary considerations for certain conditions, but they are not the immediate focus when starting hydrochlorothiazide.
