A healthcare professional is preparing to administer gentamicin 2 mg/kg via IV bolus to a client who weighs 220 lb. How many mg should the healthcare professional administer?
- A. 200 mg
- B. 100 mg
- C. 160 mg
- D. 180 mg
Correct Answer: C
Rationale: To calculate the dosage correctly, the weight in pounds must first be converted to kilograms. 220 lb / 2.2 = 100 kg. Then, multiply the weight in kg by the dosage of 2 mg/kg: 2 mg/kg 100 kg = 200 mg. Therefore, the correct dosage to administer is 200 mg, which is closest to option A. Option C (160 mg) is incorrect because it does not match the calculated dosage. Options B (100 mg) and D (180 mg) are also incorrect as they do not align with the correct calculation.

By the second postoperative day, a client has not achieved satisfactory pain relief. Based on this evaluation, which of the following actions should the nurse take, according to the nursing process?
- A. Reassess the client to determine the reasons for inadequate pain relief.
- B. Wait to see whether the pain lessens during the next 24 hours.
- C. Change the plan of care to provide different pain relief interventions.
- D. Teach the client about the plan of care for managing pain.
Correct Answer: A
Rationale: Reassessing the client is crucial to identify the reasons for inadequate pain relief. This action allows the nurse to gather more information, evaluate the current pain management interventions, and make necessary adjustments to the care plan. Waiting for the pain to lessen without taking action delays appropriate pain management. Changing the plan of care without reassessment may lead to ineffective interventions. Teaching the client about the plan of care should be based on a reassessment of the current pain relief status to ensure tailored and effective pain management strategies.
The healthcare provider is planning care for a 14-year-old client returning from scoliosis corrective surgery. Which of the following actions should receive priority in the plan?
- A. Administer antibiotic therapy for 10 days
- B. Teach the client isometric exercises for legs
- C. Assess movement and sensation of extremities
- D. Assist the client to stand up at the bedside within the first 24 hours
Correct Answer: C
Rationale: Assessing movement and sensation of extremities is the priority after scoliosis corrective surgery as it helps in early detection of any neurological deficits that may have occurred during the procedure. This assessment is essential for prompt intervention if any issues are identified. Administering antibiotics, teaching exercises, and assisting the client to stand up are important aspects of care but assessing neurological status takes precedence to ensure the client's safety and recovery.
A nurse is caring for a group of clients. How should the nurse prevent the spread of infection?
- A. Place a client with TB in a negative pressure room.
- B. Use standard precautions only.
- C. Place a client with TB in a private room.
- D. Use barrier precautions only.
Correct Answer: A
Rationale: The correct answer is to place a client with TB in a negative pressure room. Tuberculosis (TB) is an airborne infectious disease, and placing the client in a negative pressure room helps prevent the spread of the infection by containing and filtering the air within the room. Standard precautions (Choice B) are important for preventing the spread of infection in general, but specific precautions are needed for airborne diseases like TB. Placing the client in a private room (Choice C) may not provide adequate ventilation and containment of airborne pathogens. Using barrier precautions (Choice D) alone is not sufficient for preventing the airborne transmission of TB.
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.
When performing cardiac chest compressions, what is a critical concept that the nurse must understand?
- A. Push hard and deep on the chest
- B. Compress the chest at a rapid rate
- C. Perform compressions with minimal interruptions
- D. Use a two-handed technique for compressions
Correct Answer: A
Rationale: The correct answer is to 'Push hard and deep on the chest.' Effective chest compressions during CPR should be forceful and deep enough to adequately circulate blood to vital organs. This helps maintain perfusion and increases the likelihood of a successful outcome. Compressing the chest at a rapid rate (choice B) is important but not as critical as ensuring the compressions are hard and deep. Performing compressions with minimal interruptions (choice C) is also crucial to maintain blood flow. Using a two-handed technique for compressions (choice D) may be helpful but is not as critical as the depth and force of the compressions.
