Nursing Elites

1. A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?

• A. 400 mg
• B. 200 mg
• C. 1600 mg
• D. 100 mg

Correct answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day × 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.

2. When assessing a client's IV for infiltration, which finding would be unexpected for the nurse?

• A. The area around the infusion site feels warm to the touch.
• B. The infusion site is swollen and cool to the touch.
• C. The infusion line does not flush properly.
• D. There is no blood return in the infusion line.

Correct answer: A

Rationale: The correct answer is A. Warmth around the infusion site is not an expected finding with infiltration. Infiltration typically presents with swelling and coolness due to the fluid leaking into the surrounding tissue. Choices B, C, and D are incorrect because swelling, coolness, and difficulty flushing the line, as well as lack of blood return, are commonly associated with infiltration.

3. A healthcare professional is screening several clients at a neighborhood health fair. Which of the following assessment findings is the priority for referral for further care?

• A. HR 105/min
• B. BMI 25 kg/m²
• C. BP 148/92
• D. Glucose 45 mg/dL

Correct answer: D

Rationale: The correct answer is D, 'Glucose 45 mg/dL.' Glucose level of 45 mg/dL indicates hypoglycemia, which is a critical condition requiring immediate attention to prevent complications like seizures, loss of consciousness, and even coma. Hypoglycemia can lead to serious adverse outcomes if not promptly addressed. Choices A, B, and C do not represent immediate life-threatening conditions and can be managed as part of routine care, unlike hypoglycemia which demands urgent intervention.

4. Twenty minutes after starting a heat application, the client mentions that the heating pad no longer feels warm enough. What is the best response by the LPN/LVN?

• A. That indicates you have derived the maximum benefit, and the heat can be removed.
• B. Your blood vessels are dilating and removing the heat from the site.
• C. We will increase the temperature by 5 degrees when the pad no longer feels warm.
• D. The body's receptors adapt over time as they are exposed to heat.

Correct answer: D

Rationale: Choice D is the correct response. The body's receptors adapt to the heat over time, which can explain why the client no longer perceives the warmth from the heating pad. This phenomenon is known as thermal adaptation. Choices A, B, and C are incorrect. Choice A is inaccurate because the client not feeling the warmth does not necessarily mean they have derived the maximum benefit. Choice B incorrectly states that blood vessels dilating remove heat, which is not accurate. Choice C suggests increasing the temperature when the pad no longer feels warm, which could potentially lead to burns or discomfort for the client.

5. A nurse is caring for a client who has a surgical wound. Which of the following laboratory values places the client at risk for poor wound healing?

• A. Serum albumin 3 g/dL
• B. Total lymphocyte count 2400/mm3
• C. HCT 42%
• D. HGB 16 g/dL

Correct answer: A

Rationale: The correct answer is A: Serum albumin 3 g/dL. Low levels of serum albumin indicate poor nutritional status and can impair wound healing. Total lymphocyte count, HCT, and HGB levels are not directly related to wound healing and do not pose a significant risk for poor wound healing in this context. Total lymphocyte count reflects the immune status, HCT measures the percentage of red blood cells in blood, and HGB measures the amount of hemoglobin in blood.
