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 with a leg fracture reports increased pain and swelling. What should the nurse suspect?

• A. Compartment syndrome
• B. Deep vein thrombosis
• C. Wound infection
• D. All of the above

Correct answer: A

Rationale: Increased pain and swelling in a fracture could indicate compartment syndrome, a serious condition requiring urgent care. Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to compromised blood flow and potential tissue damage. Deep vein thrombosis is less likely in this scenario as the symptoms are more indicative of compartment syndrome. Wound infection would typically present with localized signs of infection at the wound site, such as redness, warmth, and purulent drainage, rather than diffuse pain and swelling.

3. The client is being educated by the nurse about the side effects of prednisone. Which side effect should the client be instructed to report immediately?

• A. Weight gain.
• B. Increased appetite.
• C. Hyperglycemia.
• D. Fever or sore throat.

Correct answer: D

Rationale: The correct answer is D: Fever or sore throat. These symptoms should be reported immediately as they could indicate an infection, which can be serious in clients taking prednisone due to its immunosuppressive effects. Choices A and B are common side effects of prednisone but are not typically considered urgent. Choice C, hyperglycemia, is a known side effect of prednisone but is not an immediate concern compared to the potential of an infection signaled by fever or sore throat.

4. What are the final factors that contribute to blood pressure? (Select all that apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Neuroendocrine hormones play a crucial role in regulating blood pressure by influencing factors like fluid balance, blood volume, and vessel constriction. While heart rate, stroke volume, and peripheral resistance are important factors affecting blood pressure, the final parameters that directly produce blood pressure are influenced by neuroendocrine hormones. Therefore, choice D is the correct answer. Choices A, B, and C are involved in the regulation of blood pressure but are not the final parameters that directly produce it.

5. A client who is 24 weeks pregnant presents with a complaint of feeling dizzy when lying on her back. What is the best response by the nurse?

• A. Advise the client to lie on her side
• B. Encourage the client to drink more fluids
• C. Suggest the client elevate her legs when lying down
• D. Recommend the client take short walks throughout the day

Correct answer: A

Rationale: The correct answer is to advise the client to lie on her side. Lying on the side can prevent the compression of the vena cava, which can cause dizziness in pregnant women. Encouraging the client to drink more fluids (Choice B) may be beneficial for other conditions but is not the best response for dizziness when lying on her back. Suggesting the client elevate her legs when lying down (Choice C) is not directly related to the issue described by the client. Recommending the client take short walks throughout the day (Choice D) may be helpful for other pregnancy-related symptoms but is not the most appropriate action for dizziness when lying on her back.
