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 foul-smelling drainage from an incision on the upper left arm is admitted with a suspected methicillin-resistant Staphylococcus aureus (MRSA). Which nursing interventions should the nurse include in the plan of care? (Select all that apply.)

• A. Send wound drainage for culture and sensitivity.
• B. Institute contact precautions for staff and visitors.
• C. Use standard precautions and wear a mask.
• D. Monitor the client's white blood cell count.

Correct answer: B

Rationale: When dealing with a client suspected of having MRSA, the nurse should implement contact precautions to prevent the spread of infection. This includes using gowns and gloves, along with following proper hand hygiene practices. Sending wound drainage for culture and sensitivity may be necessary for diagnostic purposes, but it is not directly related to preventing the spread of infection in this case. Using standard precautions and wearing a mask are not sufficient when dealing with MRSA; contact precautions are specifically required to prevent transmission. Monitoring the client's white blood cell count is important in assessing infection status but is not a primary intervention to prevent the spread of MRSA.

3. During the shift change report at an acute care hospital, the charge nurse assigns the Licensed Practical Nurse (LPN) to care for a client. Which task is within the LPN's scope?

• A. Administering IV medication
• B. Conducting initial client assessments
• C. Providing wound care for a stage III pressure ulcer
• D. Teaching a diabetic client about insulin administration

Correct answer: C

Rationale: The correct answer is C. LPNs are trained to provide basic nursing care such as wound care. Providing wound care for a stage III pressure ulcer falls within the LPN's scope of practice. Administering IV medication (choice A) requires a higher level of skill and is usually the responsibility of registered nurses. Conducting initial client assessments (choice B) demands more advanced training and is typically performed by registered nurses. Teaching a diabetic client about insulin administration (choice D) involves patient education and is usually within the scope of registered nurses or other healthcare professionals with specific training in diabetic care.

4. A client with a history of atrial fibrillation is prescribed warfarin. Which lab value should the nurse monitor to assess the effectiveness of this medication?

• A. Hemoglobin
• B. White blood cell count
• C. Platelet count
• D. INR

Correct answer: D

Rationale: The correct answer is D, INR (International Normalized Ratio). The INR is used to monitor the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication commonly prescribed for conditions like atrial fibrillation. Monitoring the INR helps healthcare providers ensure that the blood is clotting within a therapeutic range. Hemoglobin (Choice A), white blood cell count (Choice B), and platelet count (Choice C) are not directly related to monitoring the effectiveness of warfarin therapy in this context.

5. The healthcare provider is preparing to administer an IM injection to an adult client. Which site is the preferred location for this injection?

• A. Deltoid muscle
• B. Vastus lateralis muscle
• C. Ventrogluteal muscle
• D. Dorsogluteal muscle

Correct answer: C

Rationale: The ventrogluteal site is the preferred site for IM injections in adults due to its muscle mass and low risk of nerve injury. The deltoid muscle, although commonly used for vaccines in adults due to easy accessibility, has a smaller muscle mass making it less ideal for IM injections. The vastus lateralis muscle is typically used in infants and young children, not in adults. The dorsogluteal site has a higher risk of injury to the sciatic nerve and is no longer recommended for IM injections in any age group.
