Nursing Elites

1. The client with a history of heart failure is taking furosemide (Lasix). Which laboratory result should the nurse monitor closely?

• A. Serum sodium.
• B. Serum potassium.
• C. Serum calcium.
• D. Serum magnesium.

Correct answer: B

Rationale: Furosemide (Lasix) is a loop diuretic that can lead to potassium loss, causing hypokalemia. Monitoring serum potassium levels is crucial to prevent complications such as cardiac dysrhythmias associated with low potassium levels.

2. A 40-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The combination of symptoms including fatigue, polyuria, polydipsia, along with laboratory findings of hyperglycemia and ketonuria strongly suggest type 1 diabetes mellitus. In type 1 diabetes mellitus, there is a deficiency of insulin leading to high blood sugar levels (hyperglycemia) and the breakdown of fats producing ketones, causing ketonuria. Type 2 diabetes mellitus typically presents differently and is more common in older individuals. Diabetes insipidus is characterized by excessive thirst and urination due to a deficiency of antidiuretic hormone, distinct from the provided clinical scenario. Hyperthyroidism may present with some overlapping symptoms like fatigue, but it does not account for the specific laboratory findings of hyperglycemia and ketonuria seen in this case.

3. 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.

4. During an admission physical assessment, the nurse is examining a newborn who is small for gestational age (SGA). Which finding should the nurse report immediately to the pediatric healthcare provider?

• A. Heel stick glucose of 65 mg/dL.
• B. Head circumference of 35 cm (14 inches).
• C. Widened, tense, bulging fontanel.
• D. High-pitched shrill cry.

Correct answer: C

Rationale: A widened, tense, bulging fontanel is a critical finding in a newborn as it can indicate increased intracranial pressure. This condition requires immediate attention and intervention to prevent further complications. Monitoring fontanel status is crucial in assessing the newborn's neurological well-being and ensuring early detection of potential issues.

5. The client has acute pancreatitis. Which nursing intervention is the highest priority?

• A. Administer pain medication as prescribed.
• B. Monitor the client's serum amylase and lipase levels.
• C. Encourage oral intake of clear liquids.
• D. Assess the client's bowel sounds every 4 hours.

Correct answer: A

Rationale: Administering pain medication as prescribed is the highest priority when caring for a client with acute pancreatitis. Acute pancreatitis is often associated with severe abdominal pain, and alleviating this pain is crucial for the client's comfort and well-being. Pain management can also help reduce stress on the pancreas and promote recovery. Monitoring serum amylase and lipase levels, encouraging oral intake of clear liquids, and assessing bowel sounds are important interventions but addressing the client's pain takes precedence to provide immediate relief and improve outcomes.
