1. A client is to receive cimetidine (Tagamet) 300 mg q6h IVP. The preparation arrives from the pharmacy diluted in 50 ml of 0.9% NaCl. The nurse plans to administer the IVPB dose over 20 minutes. For how many ml/hr should the infusion pump be set to deliver the secondary infusion?
- A. 75 ml/hr
- B. 150 ml/hr
- C. 225 ml/hr
- D. 300 ml/hr
Correct answer: B
Rationale: To calculate the infusion rate, set up a ratio proportion problem: 50 ml/20 min = x ml/60 min. Cross multiply to solve: 50 × 60 / 20 = 150 ml/hr. Therefore, the infusion pump should be set to deliver the secondary infusion at a rate of 150 ml/hr. Option A, 75 ml/hr, is incorrect because it does not account for the correct calculation. Option C, 225 ml/hr, is incorrect as it is too high a rate based on the calculation. Option D, 300 ml/hr, is also incorrect as it does not align with the correct calculation for the infusion rate.
2. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?
- A. BP 142/88 mmHg
- B. 2+ edema of fingers and hands
- C. Radial pulse volume is +3
- D. Capillary refill time is 2 seconds
Correct answer: B
Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.
3. The healthcare provider is preparing an older client for discharge. Which method is best for the provider to use when evaluating the client's ability to perform a dressing change at home?
- A. Determine the client's feelings about changing the dressing.
- B. Ask the client to write a description of the procedure.
- C. Have a family member evaluate the client's ability to change the dressing.
- D. Observe the client performing an unassisted dressing change.
Correct answer: D
Rationale: Direct observation of the client performing the skill is the most effective method to assess the client's ability to independently change the dressing. This allows the healthcare provider to evaluate the client's technique, understanding, and readiness to perform the task at home. Choices A, B, and C are not as reliable as directly observing the client performing the dressing change. Determining the client's feelings may not accurately reflect their ability, asking the client to write about the procedure may not demonstrate their practical skills, and having a family member evaluate might not provide an accurate assessment of the client's ability.
4. While instructing a male client's wife in the performance of passive range-of-motion exercises to his contracted shoulder, the nurse observes that she is holding his arm above and below the elbow. What nursing action should the nurse implement?
- A. Acknowledge that she is supporting the arm correctly.
- B. Encourage her to keep the joint uncovered to maintain warmth.
- C. Reinforce the need to grip directly under the joint for better support.
- D. Instruct her to grip directly over the joint for better motion.
Correct answer: A
Rationale: The wife is correctly performing the passive range-of-motion exercises by holding the arm above and below the elbow. The nurse should acknowledge this correct technique (A). It is essential to keep the joint uncovered (B) during exercises, while ensuring the rest of the body remains covered for warmth and privacy. Choices (C) and (D) do not provide optimal support to the joint for effective movement.
5. The healthcare provider identifies a potential for infection in a client with partial-thickness (second-degree) and full-thickness (third-degree) burns. What intervention has the highest priority in decreasing the client's risk of infection?
- A. Administration of plasma expanders
- B. Use of careful handwashing technique
- C. Application of a topical antibacterial cream
- D. Limiting visitors to the client with burns
Correct answer: B
Rationale: Proper handwashing technique is crucial in preventing the transmission of infections, especially in clients with burns where the risk of infection is high. It is the most effective intervention to reduce the risk of contamination and promote healing in these clients. While plasma expanders, topical antibacterial creams, and visitor restrictions are important considerations in burn care, meticulous hand hygiene takes precedence in preventing infections. Handwashing helps remove pathogens that could lead to infections, making it essential in the care of clients with burns.
