Nursing Elites

1. The nurse is assessing a client who has been receiving total parenteral nutrition (TPN) for several days. Which complication should the nurse monitor for?

• A. Hyperglycemia
• B. Hypoglycemia
• C. Hyponatremia
• D. Hypokalemia

Correct answer: B

Rationale: The correct answer is B: Hypoglycemia. When a client is receiving total parenteral nutrition (TPN) with a high glucose content, the risk of hypoglycemia is significant due to sudden increases in insulin release in response to the glucose load. The nurse should monitor for signs and symptoms of hypoglycemia such as shakiness, sweating, palpitations, and confusion. Hyperglycemia (choice A) is not typically a complication of TPN as the high glucose content is more likely to cause hypoglycemia. Hyponatremia (choice C) and hypokalemia (choice D) are electrolyte imbalances that can occur in clients receiving TPN, but hypoglycemia is the more common and immediate concern that the nurse should monitor for.

2. A client with diabetes exhibits a blood sugar of 350 mg/dL. What is the nurse's best action?

• A. Administer insulin as prescribed
• B. Provide a carbohydrate-controlled snack
• C. Encourage physical activity
• D. Recheck the blood sugar

Correct answer: A

Rationale: In a client with diabetes presenting with a blood sugar level of 350 mg/dL, the best action for the nurse is to administer insulin as prescribed. High blood sugar levels can lead to complications like diabetic ketoacidosis, making prompt insulin administration crucial to lower the blood glucose level. Providing a carbohydrate-controlled snack would be inappropriate as it may further elevate blood sugar levels. Encouraging physical activity is not advisable when the blood sugar is significantly high, as exercise can raise blood sugar levels. Rechecking the blood sugar is necessary after administering insulin to monitor the response to treatment.

3. The healthcare provider is caring for a client with a chest tube following a pneumothorax. Which assessment finding should be reported to the healthcare provider immediately?

• A. Continuous bubbling in the water seal chamber
• B. Absence of drainage in the collection chamber
• C. Tidaling in the water seal chamber
• D. Presence of subcutaneous emphysema around the insertion site

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber should be reported to the healthcare provider immediately. This finding may indicate an air leak, which can compromise the effectiveness of the chest tube in re-expanding the lung. Absence of drainage in the collection chamber (choice B) may signify that the chest tube is blocked, but it does not pose an immediate threat to the client's condition. Tidaling in the water seal chamber (choice C) is an expected finding and indicates proper functioning of the chest tube system. Presence of subcutaneous emphysema around the insertion site (choice D) suggests air leakage but is not as urgent as continuous bubbling in the water seal chamber.

4. A client with chronic obstructive pulmonary disease (COPD) is receiving home oxygen therapy. What is the most important instruction the nurse should provide?

• A. Use oxygen at the highest flow rate tolerated
• B. Avoid wearing oxygen during physical activity
• C. Do not smoke while using oxygen
• D. Store oxygen tanks in a cool, dark place

Correct answer: C

Rationale: The correct answer is C: 'Do not smoke while using oxygen.' Smoking while using oxygen can lead to a serious fire hazard, as oxygen supports combustion. This instruction is crucial to prevent potential harm to the client. Choices A, B, and D are incorrect. Using oxygen at the highest flow rate tolerated can be harmful, avoiding wearing oxygen during physical activity may limit the client's mobility unnecessarily, and storing oxygen tanks in a cool, dark place, although important, is not as critical as the instruction to avoid smoking while using oxygen.

5. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

• A. 400 mg/mL
• B. 500 mg/mL
• C. 450 mg/mL
• D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.
