1. The healthcare professional is preparing to administer potassium chloride intravenously to a client with hypokalemia. Which action is most important?
- A. Monitor the client's respiratory rate
- B. Check the client's urine output
- C. Administer the potassium chloride as a rapid IV push
- D. Dilute the potassium chloride in an appropriate IV solution
Correct answer: D
Rationale: The correct answer is to dilute the potassium chloride in an appropriate IV solution. Potassium chloride should never be administered as a rapid IV push as it can lead to severe complications, including cardiac arrhythmias. Diluting the medication and administering it slowly helps reduce the risk of adverse effects. Monitoring the client's respiratory rate (Choice A) and checking urine output (Choice B) are important aspects of patient assessment but not the most crucial when administering potassium chloride. Administering potassium chloride as a rapid IV push (Choice C) is dangerous and can result in serious harm to the client.
2. During a blood transfusion, which observation indicates that the client is experiencing a transfusion reaction?
- A. The client reports feeling warm and flushed.
- B. The client develops a rash on the chest and back.
- C. The client experiences chills and a fever.
- D. The client complains of back pain and shortness of breath.
Correct answer: D
Rationale: Complaints of back pain and shortness of breath are classic signs of a transfusion reaction, specifically indicating a hemolytic reaction. This reaction can lead to the release of hemoglobin into the bloodstream, causing back pain and shortness of breath due to clot formation in the blood vessels, leading to decreased oxygen delivery. Warmth, flushing, rash, chills, and fever are more commonly associated with allergic reactions or febrile non-hemolytic reactions during transfusions. Therefore, options A, B, and C are incorrect in this context.
3. The nurse is caring for a client with cirrhosis of the liver. Which finding should the LPN/LVN report to the healthcare provider immediately?
- A. Yellowing of the skin and eyes
- B. Dark-colored urine
- C. Abdominal distention
- D. Confusion
Correct answer: A
Rationale: Yellowing of the skin and eyes (jaundice) is a classic sign of liver dysfunction in clients with cirrhosis. Jaundice indicates the accumulation of bilirubin in the body due to impaired liver function. This finding suggests worsening liver damage and should be reported immediately to the healthcare provider for prompt evaluation and management. Dark-colored urine (choice B) is also a concerning symptom in liver disease, indicating possible bilirubin presence, but it is not as urgent as jaundice. Abdominal distention (choice C) and confusion (choice D) are common in cirrhosis but do not indicate an immediate need for healthcare provider notification compared to jajsondice.
4. A healthcare provider is assessing a client with a diagnosis of acute pancreatitis. Which laboratory value would be most concerning?
- A. Serum amylase of 200 U/L
- B. Serum lipase of 250 U/L
- C. Blood glucose of 200 mg/dL
- D. Serum calcium of 7.5 mg/dL
Correct answer: D
Rationale: In acute pancreatitis, hypocalcemia (low serum calcium) is a critical finding that is associated with a poor prognosis and requires immediate attention. Serum amylase and lipase are typically elevated in acute pancreatitis due to pancreatic inflammation, but they are not indicators of severity. Blood glucose levels may be elevated due to stress or underlying conditions but are not directly related to the severity of acute pancreatitis. Therefore, the most concerning value in this scenario is the low serum calcium level, which can have significant implications for the client's prognosis.
5. A healthcare professional is preparing to administer gentamicin 2 mg/kg via IV bolus to a client who weighs 220 lb. How many mg should the healthcare professional administer?
- A. 200 mg
- B. 100 mg
- C. 160 mg
- D. 180 mg
Correct answer: C
Rationale: To calculate the dosage correctly, the weight in pounds must first be converted to kilograms. 220 lb / 2.2 = 100 kg. Then, multiply the weight in kg by the dosage of 2 mg/kg: 2 mg/kg × 100 kg = 200 mg. Therefore, the correct dosage to administer is 200 mg, which is closest to option A. Option C (160 mg) is incorrect because it does not match the calculated dosage. Options B (100 mg) and D (180 mg) are also incorrect as they do not align with the correct calculation.
