Nursing Elites

1. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?

• A. Metabolic acidosis.
• B. Respiratory acidosis.
• C. Metabolic alkalosis.
• D. Respiratory alkalosis.

Correct answer: B

Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.

2. A client with cirrhosis is receiving lactulose. What is the desired effect of this medication?

• A. Decrease blood glucose levels
• B. Reduce serum ammonia levels
• C. Increase platelet count
• D. Lower serum bilirubin levels

Correct answer: B

Rationale: The correct answer is B: Reduce serum ammonia levels. Lactulose is used to reduce serum ammonia levels in clients with cirrhosis, helping to prevent hepatic encephalopathy. Lactulose works by acidifying the colon, trapping ammonia for excretion. Decreasing blood glucose levels (choice A) is not the primary effect of lactulose. Increasing platelet count (choice C) and lowering serum bilirubin levels (choice D) are not direct effects of lactulose in the management of cirrhosis.

3. A client with hypertension is prescribed a low-sodium diet. Which food should the client avoid?

• A. Fresh fruits
• B. Processed cheese
• C. Whole grain bread
• D. Fresh vegetables

Correct answer: B

Rationale: The correct answer is B: Processed cheese. Processed cheese is high in sodium and should be avoided in a low-sodium diet for clients with hypertension. Fresh fruits, whole grain bread, and fresh vegetables are generally low in sodium and can be part of a healthy diet for clients with hypertension.

4. What is the most effective therapy for maintaining remission of acute lymphoblastic leukemia in a child?

• A. Surgery to remove enlarged lymph nodes
• B. Long-term chemotherapy
• C. Nutritional supplements to enhance blood cell production
• D. Blood transfusions to replace ineffective red cells

Correct answer: B

Rationale: The correct answer is B: Long-term chemotherapy. In the case of acute lymphoblastic leukemia, the most effective approach for maintaining remission is long-term chemotherapy, particularly with methotrexate, a chemotherapeutic agent. Surgery to remove enlarged lymph nodes (choice A) is not the primary treatment for leukemia. Nutritional supplements (choice C) may be beneficial for overall health but are not the mainstay of leukemia treatment. Blood transfusions (choice D) are used to manage anemia in leukemia but do not address the underlying disease process.

5. A client who took a camping vacation two weeks ago in a country with a tropical climate comes to the clinic describing vague symptoms and diarrhea for the past week. Which finding is most important for the nurse to report to the HCP?

• A. Weakness and fatigue
• B. Intestinal cramping
• C. Weight loss
• D. Jaundiced sclera

Correct answer: D

Rationale: The most important finding to report to the healthcare provider is a jaundiced sclera. Jaundice suggests liver involvement, which can be a sign of a serious underlying condition. Weakness and fatigue, intestinal cramping, and weight loss are important symptoms, but jaundice indicates a more urgent issue that needs immediate attention.
