1. Before administration of a stat dose of potassium chloride IV for a client with hypokalemia, what is the most important action for the nurse?
- A. Ensure the IV is flowing freely
- B. Mix the medication thoroughly
- C. Check the client’s electrolyte levels
- D. Obtain a baseline ECG
Correct answer: A
Rationale: The most crucial action for the nurse before administering a stat dose of potassium chloride IV to a client with hypokalemia is to ensure the IV is flowing freely. A freely flowing IV is essential to safely and effectively deliver potassium chloride, helping to prevent infusion-related issues. Checking the client's electrolyte levels or obtaining a baseline ECG may be important but are not the most critical actions before administering the medication. Mixing the medication thoroughly is not applicable in this scenario as potassium chloride is typically provided ready to use.
2. A client who fell 20 feet from the roof of his home has multiple injuries, including a right pneumothorax. Chest tubes were inserted in the emergency department prior to his transfer to the intensive care unit (ICU). The nurse observes that the suction control chamber is bubbling at the -10 cm H20 mark, with fluctuation in the water seal, and over the past hour, 75 mL of bright red blood is measured in the collection chamber. Which intervention should the nurse implement?
- A. Increase wall suction to eliminate fluctuation in the water seal.
- B. Give blood from the collection chamber as autotransfusion.
- C. Add sterile water to the suction control chamber.
- D. Manipulate blood in tubing to drain into chamber.
Correct answer: C
Rationale: The correct intervention for the nurse to implement is to add sterile water to the suction control chamber. This action helps maintain the proper functioning of the chest tube system by regulating the negative pressure. Increasing wall suction is not recommended as it could lead to excessive negative pressure. Giving blood from the collection chamber as autotransfusion is inappropriate and poses a risk of complications such as air embolism. Manipulating blood in the tubing is also unsafe as it could introduce air into the system, increasing the risk of complications for the client.
3. The nurse is caring for a client with cirrhosis of the liver. Which clinical finding is most concerning?
- A. Jaundice.
- B. Ascites.
- C. Spider angiomas.
- D. Asterixis.
Correct answer: D
Rationale: The correct answer is D, Asterixis. Asterixis, also known as liver flap, is a sign of hepatic encephalopathy, a severe complication of liver disease that necessitates immediate attention. While jaundice (choice A), ascites (choice B), and spider angiomas (choice C) are common clinical findings in cirrhosis, asterixis is the most concerning due to its association with hepatic encephalopathy, which can lead to altered mental status and even coma. Jaundice, ascites, and spider angiomas are also important signs in cirrhosis, but asterixis indicates a more critical condition requiring urgent intervention.
4. A client is prescribed warfarin for the prevention of thromboembolism. What dietary instruction should the nurse provide?
- A. Increase intake of green leafy vegetables
- B. Maintain a consistent intake of vitamin K-rich foods
- C. Avoid all foods containing vitamin K
- D. Consume a high-protein diet
Correct answer: B
Rationale: The correct answer is B. Maintaining a consistent intake of vitamin K-rich foods is important for patients taking warfarin as it helps keep the effects of the medication stable. Choice A is incorrect because while green leafy vegetables are high in vitamin K, they should not be avoided completely but rather consumed consistently. Choice C is also incorrect as avoiding all foods containing vitamin K can lead to fluctuations in warfarin's effectiveness. Choice D is incorrect as a high-protein diet is not specifically recommended for patients taking warfarin.
5. In a community health setting, which individual is at highest risk for contracting an HIV infection?
- A. 17-year-old who is sexually active with numerous partners
- B. 34-year-old homosexual in a monogamous relationship
- C. 30-year-old cocaine user who inhales and smokes drugs
- D. 45-year-old who has received two blood transfusions in the past 6 months
Correct answer: C
Rationale: The correct answer is C. Substance abuse, particularly using shared inhalation equipment like needles and pipes for drug inhalation, significantly increases the risk of contracting HIV. Choice A, the 17-year-old with multiple sexual partners, poses a risk of HIV transmission through sexual contact, but it is lower compared to the direct risk associated with sharing drug paraphernalia. Choice B, the 34-year-old homosexual in a monogamous relationship, is at lower risk since being in a monogamous relationship reduces exposure to HIV. Choice D, the 45-year-old who received blood transfusions, is also at lower risk as blood transfusions are now screened for HIV, decreasing the likelihood of transmission through this route.
