Nursing Elites

1. 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.

2. A client is diagnosed with type 1 diabetes mellitus. Which instruction about insulin administration should the nurse emphasize?

• A. Rotate injection sites to prevent tissue damage
• B. Inject insulin into the same site to increase absorption
• C. Only use insulin pens
• D. Mix different types of insulin in the same syringe

Correct answer: C

Rationale: The correct answer is to only use insulin pens. This is because insulin pens provide a convenient and accurate way to administer insulin. Rotating injection sites is important to prevent tissue damage and promote consistent insulin absorption, making choice A incorrect. Injecting insulin into the same site can lead to lipodystrophy and is not recommended, making choice B incorrect. Mixing different types of insulin in the same syringe can alter their action profiles and is generally not recommended, making choice D incorrect.

3. A client with a history of hypertension is admitted to the hospital for a suspected myocardial infarction. Which of the following is the priority nursing action?

• A. Administer oxygen as prescribed
• B. Perform an ECG
• C. Obtain a detailed health history
• D. Monitor vital signs regularly

Correct answer: B

Rationale: The priority nursing action in this scenario is to perform an ECG. An ECG is crucial in confirming myocardial infarction promptly and guiding immediate treatment decisions. Administering oxygen as prescribed is important but not the priority over confirming the diagnosis. Obtaining a detailed health history is relevant but does not take precedence over immediate diagnostic confirmation. While monitoring vital signs regularly is essential, performing an ECG is the priority action in this scenario to guide timely management.

4. The nurse is caring for a client with increased intracranial pressure (ICP). Which position should the nurse avoid?

• A. Keeping the head of the bed elevated at 30 degrees
• B. Positioning the client in the prone position
• C. Placing the client in a lateral recumbent position
• D. Elevating the client's legs

Correct answer: B

Rationale: The correct answer is B: Positioning the client in the prone position. Placing the client in the prone position should be avoided in a client with increased intracranial pressure (ICP) as it can further raise ICP. The prone position can hinder venous return and increase pressure within the cranial vault, potentially worsening the client's condition. Keeping the head of the bed elevated at 30 degrees helps promote venous drainage and reduce ICP. Placing the client in a lateral recumbent position can also assist in reducing ICP by optimizing cerebral perfusion. Elevating the client's legs can help improve venous return and maintain adequate cerebral blood flow, making it a suitable positioning intervention for managing increased ICP.

5. What safety measure should be implemented when administering chemotherapy?

• A. Use protective gloves and gown
• B. Prepare the medication in a designated area
• C. Administer the medication at the appropriate rate
• D. Verify the two client identifiers

Correct answer: A

Rationale: When administering chemotherapy, it is crucial to use protective gloves and a gown to protect against exposure to hazardous drugs that can be harmful through skin contact. Choice B is incorrect because chemotherapy medication should be prepared in a designated area to prevent contamination and ensure accurate preparation. Choice C is incorrect as chemotherapy should be administered at the appropriate rate to ensure patient safety and avoid adverse effects. Choice D is incorrect as verifying client identifiers is important for medication administration in general but not a specific safety measure related to chemotherapy administration.
