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. The nurse is with a client when the healthcare provider explains that the biopsy classifies the results as a T1N0M0 tumor. What response should the nurse provide first?

• A. The letters represent tumor size, node involvement, and metastasis in cancer staging.
• B. The letters stand for tumor size, node involvement, and metastasis.
• C. Let me explain the cancer staging to you.
• D. Would you like further clarification on the tumor staging?

Correct answer: B

Rationale: Choice B is the correct answer as it accurately explains that the letters T, N, and M in cancer staging represent tumor size, node involvement, and metastasis, respectively. Understanding this staging system helps the client comprehend the extent and severity of the disease. Choices A, C, and D are incorrect. Choice A has the correct information but is not the most precise response. Choice C is vague and does not directly address the client's need for clarification. Choice D offers further clarification without directly addressing the initial explanation provided by the healthcare provider.

3. A client is admitted with Atrial Fibrillation and is administered amiodarone (Cordarone). What therapeutic response should the nurse anticipate?

• A. Conversion of irregular heart rate to regular heart rhythm
• B. Pulse oximetry readings within normal range during activity
• C. Peripheral pulse points with adequate capillary refill
• D. Increase in exercise tolerance without shortness of breath

Correct answer: A

Rationale: The correct answer is A: Conversion of irregular heart rate to regular heart rhythm. Amiodarone is a medication commonly used to restore and maintain normal heart rhythm in clients with atrial fibrillation. It works by slowing down the electrical signals in the heart, helping to regulate the heartbeat. Choices B, C, and D are incorrect because they do not directly relate to the therapeutic response expected from administering amiodarone in a client with atrial fibrillation. Pulse oximetry readings, peripheral pulses, capillary refill, and exercise tolerance are important assessments but are not the primary therapeutic goal of using amiodarone in this situation.

4. A nurse is developing a care plan for a client with chronic pain. What interventions should be included to help manage pain?

• A. Administer pain medication around the clock
• B. Teach relaxation techniques
• C. Encourage physical activity
• D. All of the above

Correct answer: D

Rationale: In managing chronic pain, it is essential to employ a multi-faceted approach. Administering pain medication around the clock helps maintain consistent pain relief. Teaching relaxation techniques such as deep breathing or guided imagery can help reduce muscle tension and promote relaxation, which can alleviate pain. Encouraging physical activity, tailored to the client's abilities, can help improve overall physical functioning and reduce pain perception. Therefore, combining all these interventions (pain medication, relaxation techniques, and physical activity) provides a comprehensive approach to pain management, addressing different aspects of the client's experience with chronic pain. This holistic approach is more effective than using a single intervention alone, making 'All of the above' the correct choice.

5. The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?

• A. Alkalosis
• B. Acidosis
• C. Normal serum pH
• D. Incompatible with life

Correct answer: C

Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.
