Nursing Elites

1. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?

• A. They involve antigen-antibody complexes.
• B. They are mediated by T cells and do not involve antibodies.
• C. They result in immediate allergic reactions.
• D. They are the least severe form of hypersensitivity.

Correct answer: B

Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.

2. A client who had surgery yesterday is becoming increasingly anxious. The client’s respiratory rate has increased to 38 breaths/minute. The client has a nasogastric tube to low intermittent suction with 500 ml of yellow-green drainage over the last four hours. The client's arterial blood gases (ABGs) indicate a decreased CO2 and an increased serum pH. Which serum laboratory value should the nurse monitor first?

• A. Electrolytes.
• B. Creatinine.
• C. Blood urea nitrogen.
• D. Glucose.

Correct answer: A

Rationale: The correct answer is A, Electrolytes. In this scenario, the client is at risk for metabolic alkalosis due to the loss of gastric secretions through the nasogastric tube. Monitoring electrolytes is crucial to assess the levels of sodium, potassium, chloride, and bicarbonate, which are important in maintaining the acid-base balance of the body. Changes in these electrolyte levels can provide valuable information about the client's fluid status and acid-base balance. Creatinine, blood urea nitrogen, and glucose levels are important parameters to monitor in different situations but are not the priority in this case of potential metabolic alkalosis.

3. During a paracentesis, two liters of fluid are removed from the abdomen of a client with ascites. A drainage bag is placed, and 50 ml of straw-colored fluid drains within the first hour. What action should the nurse implement?

• A. Palpate for abdominal distention
• B. Send fluid to the lab for analysis
• C. Continue to monitor the fluid output
• D. Clamp the drainage tube for 5 minutes

Correct answer: C

Rationale: Continuing to monitor the fluid output is the appropriate action in this situation. Monitoring the fluid output helps the nurse assess the client's ongoing response to the procedure and detect any sudden changes, such as increased or decreased drainage rate, which could indicate complications. Palpating for abdominal distention, sending fluid to the lab for analysis, or clamping the drainage tube are not necessary actions at this point, as the priority is to monitor the client's condition post-procedure.

4. 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.

5. A client with ulcerative colitis is experiencing frequent diarrhea. What is the priority nursing diagnosis?

• A. Risk for impaired skin integrity
• B. Fluid volume deficit
• C. Imbalanced nutrition: less than body requirements
• D. Activity intolerance

Correct answer: B

Rationale: The correct answer is B: Fluid volume deficit. In a client with ulcerative colitis experiencing frequent diarrhea, the priority nursing diagnosis is addressing the potential fluid volume deficit due to significant fluid loss. Maintaining adequate hydration is crucial to prevent complications associated with dehydration. While choices A, C, and D can also be concerns for a client with ulcerative colitis, addressing fluid volume deficit takes precedence as it directly impacts the client's physiological stability and can lead to serious complications if not managed promptly.
