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. When counting a client's radial pulse, the nurse notes the pulse is weak and irregular. To record the most accurate heart rate, what should the nurse do?

• A. Recheck the radial pulse in thirty minutes
• B. Palpate the radial pulse for thirty seconds and double the rate
• C. Count the apical pulse rate for sixty seconds
• D. Compare the radial pulse rate bilaterally and record the higher rate

Correct answer: C

Rationale: The correct answer is to count the apical pulse rate for sixty seconds. The apical pulse is more accurate, especially when peripheral pulses are weak or irregular. Counting the apical pulse for a full minute provides a more precise heart rate measurement. Option A is incorrect because waiting for thirty minutes is unnecessary and could delay potential interventions. Option B is incorrect because doubling the radial pulse rate may not provide an accurate representation of the heart rate. Option D is incorrect because comparing radial pulses bilaterally does not give the most accurate heart rate measurement; the apical pulse is preferred in this situation.

3. The nurse is providing care for a client with a draining postoperative wound infected with methicillin-resistant Staphylococcus aureus (MRSA). Which is the most important action for the nurse to take?

• A. Encourage increased oral fluids.
• B. Provide high-protein snacks.
• C. Change the wound dressing.
• D. Administer prescribed antibiotics.

Correct answer: D

Rationale: Administering prescribed antibiotics is crucial in treating MRSA infections. MRSA is a type of bacteria that is resistant to many antibiotics, including methicillin. Therefore, prompt administration of the appropriate antibiotics is essential to target the MRSA infection effectively. Encouraging increased oral fluids (Choice A) and providing high-protein snacks (Choice B) may be beneficial for overall recovery but are not the most important actions in treating an MRSA infection. Changing the wound dressing (Choice C) is important for wound care but does not directly address the infection caused by MRSA.

4. What should the nurse prioritize when providing discharge instructions to a client with a new colostomy?

• A. Skin care around the stoma site
• B. The schedule for colostomy bag replacement
• C. Techniques for odor control
• D. Dietary modifications

Correct answer: A

Rationale: Correct answer: Skin care around the stoma site. Proper skin care around the stoma site is crucial for preventing skin irritation and infection, which are common issues for patients with new colostomies. While the schedule for colostomy bag replacement (Option B) is important, it is not the priority during initial discharge instructions. Techniques for odor control (Option C) are relevant but secondary to skin care for a new colostomy. Dietary modifications (Option D) may be discussed later but are not the priority at this stage.

5. The client with a diagnosis of hypertension is being taught about lifestyle changes. Which recommendation is most important to include?

• A. Increase sodium intake.
• B. Engage in regular physical activity.
• C. Avoid foods high in fat.
• D. Limit fluid intake to 1 liter per day.

Correct answer: B

Rationale: Engaging in regular physical activity is crucial for individuals with hypertension as it helps lower blood pressure and improve cardiovascular health. Physical activity is known to have a significant impact on reducing hypertension and overall cardiovascular risk. Choice A, increasing sodium intake, is incorrect as reducing sodium is typically recommended for hypertension to help lower blood pressure. Choice C, avoiding foods high in fat, is beneficial for overall health but not the most crucial recommendation for hypertension management. Choice D, limiting fluid intake to 1 liter per day, is not a standard recommendation for hypertension unless advised by a healthcare provider for specific cases. Therefore, the most important recommendation for the client with hypertension is to engage in regular physical activity.
