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. A 9-year-old female client was recently diagnosed with diabetes mellitus. Which symptom will her parents most likely report?

• A. Refuses to eat her favorite meals at home.
• B. Drinks more soft drinks than previously.
• C. Voids only one or two times per day.
• D. Gained 10 pounds within one month.

Correct answer: B

Rationale: The correct answer is B. Increased thirst and fluid intake, such as drinking more soft drinks than previously, is a common symptom of diabetes mellitus in children. This increased thirst is due to the body trying to eliminate excess sugar through urination, leading to dehydration and the need for more fluids. The other choices are less likely to be directly related to the diagnosis of diabetes mellitus in this scenario.

3. The client has acute kidney injury (AKI). Which assessment finding requires immediate intervention?

• A. Urine output of 50 ml in the last hour.
• B. Serum potassium of 6.2 mEq/L.
• C. Blood pressure of 150/90 mm Hg.
• D. Serum creatinine of 2.5 mg/dL.

Correct answer: B

Rationale: An elevated serum potassium level of 6.2 mEq/L in a client with AKI can lead to life-threatening cardiac arrhythmias, necessitating immediate intervention. Hyperkalemia is a serious complication in AKI as impaired kidney function can result in the accumulation of potassium in the blood, posing a risk of cardiac arrest. Prompt treatment to lower potassium levels is crucial to prevent cardiac complications in this situation.

4. Which problem in a client requires the most immediate intervention by the nurse?

• A. Finger paresthesias related to carpal tunnel syndrome.
• B. Increasing sharp pain related to compartment syndrome.
• C. Increasing burning pain related to a Morton's neuroma.
• D. Increasing sharp pain related to plantar fasciitis.

Correct answer: B

Rationale: The correct answer is B: Increasing sharp pain related to compartment syndrome. Compartment syndrome is a serious condition where increased pressure within a muscle compartment compromises circulation and can lead to tissue damage. Immediate intervention is crucial to prevent permanent damage to muscles and nerves, including tissue necrosis and nerve injury. Choices A, C, and D do not present the same level of urgency as compartment syndrome, making them less critical for immediate intervention. Carpal tunnel syndrome, Morton's neuroma, and plantar fasciitis may cause discomfort and functional limitations but are not typically considered emergencies requiring urgent intervention like compartment syndrome.

5. The nurse is administering sevelamer (RenaGel) during lunch to a client with end-stage renal disease (ESRD). The client asks the nurse to bring the medication later. The nurse should describe which action of RenaGel as an explanation for taking it with meals?

• A. Prevents indigestion associated with the ingestion of spicy foods.
• B. Binds with phosphorus in foods and prevents absorption.
• C. Promotes stomach emptying and prevents gastric reflux.
• D. Buffers hydrochloric acid and prevents gastric erosion.

Correct answer: B

Rationale: Sevelamer (RenaGel) binds with phosphorus in foods to prevent its absorption, which is why it should be taken with meals. By taking RenaGel with meals, it can effectively bind with phosphorus from food, reducing the amount of phosphorus absorbed by the body, thus helping to manage hyperphosphatemia in clients with ESRD. Choices A, C, and D are incorrect because RenaGel's primary action is to bind with phosphorus in foods, not related to preventing indigestion, promoting stomach emptying, or buffering hydrochloric acid.
