1. Why is a client with ascites scheduled for a paracentesis procedure?
- A. To diagnose liver disease
- B. To relieve abdominal pressure
- C. To assess kidney function
- D. To reduce blood pressure
Correct answer: B
Rationale: The correct answer is B: "To relieve abdominal pressure." Paracentesis is performed to drain accumulated fluid in the peritoneal cavity, providing symptomatic relief for clients with ascites. Choice A is incorrect because paracentesis is not a diagnostic procedure for liver disease. Choice C is incorrect as assessing kidney function would typically involve different procedures. Choice D is incorrect as paracentesis does not directly impact blood pressure.
2. 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.
3. A client with cirrhosis of the liver is being cared for by the healthcare team. Which clinical manifestation indicates that the client has developed hepatic encephalopathy?
- A. Asterixis.
- B. Jaundice.
- C. Ascites.
- D. Splenomegaly.
Correct answer: A
Rationale: Asterixis, also known as flapping tremor, is a characteristic sign of hepatic encephalopathy, a severe complication of liver cirrhosis. Hepatic encephalopathy results from the liver's inability to detoxify substances in the body, leading to neurologic manifestations such as changes in mental status, confusion, and asterixis.
4. An elderly client with congestive heart failure (CHF) is admitted to the hospital. Which laboratory test result should the nurse expect to find?
- A. Elevated serum sodium level.
- B. Decreased brain natriuretic peptide (BNP) level.
- C. Increased serum creatinine level.
- D. Elevated hemoglobin and hematocrit levels.
Correct answer: C
Rationale: In clients with congestive heart failure (CHF), impaired cardiac function can lead to decreased renal perfusion, resulting in elevated serum creatinine levels. Therefore, an increased serum creatinine level is a common laboratory finding in CHF clients, indicating possible renal impairment.
5. A 35-year-old woman presents with fatigue, weight gain, and cold intolerance. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?
- A. Hypothyroidism
- B. Hyperthyroidism
- C. Thyroiditis
- D. Thyroid cancer
Correct answer: A
Rationale: The scenario describes a 35-year-old woman with symptoms of fatigue, weight gain, and cold intolerance along with high TSH and low free T4 levels. These findings are consistent with the diagnosis of hypothyroidism. In hypothyroidism, there is decreased thyroid hormone production leading to elevated TSH levels as the body tries to stimulate the thyroid to produce more hormone. The low free T4 levels indicate insufficient thyroid hormone in the blood, which can manifest as symptoms such as fatigue, weight gain, and cold intolerance.
