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. In which situation is it most important for the registered nurse (RN) working on a medical unit to provide direct supervision?

• A. A graduate nurse needs to access a client's implanted port to start an infusion of Ringer's Lactate.
• B. A postpartum nurse pulled to the unit needs to start a transfusion of packed red blood cells.
• C. A practical nurse is preparing to assist the healthcare provider with a lumbar puncture at the bedside.
• D. An unlicensed assistive personnel is preparing to weigh an obese bedfast client using a bed scale.

Correct answer: A

Rationale: Direct supervision is essential when a complex task, such as accessing an implanted port, is being performed by a less experienced healthcare provider, in this case, a graduate nurse. This oversight ensures patient safety and proper execution of the procedure, especially when it is the nurse's first time performing such a task.

3. A client with myelogenous leukemia is receiving an autologous bone marrow transplantation (BMT). What is the priority intervention that the nurse should implement when the bone marrow is repopulating?

• A. Administer sargramostim (Leukine, Prokine).
• B. Infuse PRBC and platelet transfusions.
• C. Give parenteral prophylactic antibiotics.
• D. Maintain a protective isolation environment.

Correct answer: D

Rationale: Maintaining a protective isolation environment is crucial during the repopulation of bone marrow post-transplant to reduce the risk of infections. The client's immune system is compromised during this period, making them highly susceptible to infections. By implementing protective isolation measures, the nurse can help prevent exposure to pathogens, safeguarding the client's health and supporting the success of the transplantation.

4. 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.

5. The healthcare provider is planning care for a non-potty-trained child with nephrotic syndrome. Which intervention provides the best means of determining fluid retention?

• A. Weigh the child daily.
• B. Observe the lower extremities for pitting edema.
• C. Measure the child's abdominal girth weekly.
• D. Weigh the child's wet diapers.

Correct answer: A

Rationale: Daily weighing is the most accurate method to monitor fluid retention in a child with nephrotic syndrome. Changes in weight can indicate fluid retention or loss, which is crucial in managing nephrotic syndrome. Observing for pitting edema and measuring abdominal girth are also important assessments, but daily weighing provides more immediate and precise information about fluid status.
