NCLEX-PN 3000 Questions and Answers. Rationales provided. Rated A+ The parent of a preschooler with chickenpox asks the nurse about measures to make the child comfortable. The nurse instructs the p... arent to avoid administering aspirin or any other product that contains salicylates. When given to children with chickenpox, aspirin has been linked to which disorder? 1. Guillain-Barré syndrome 2. Rheumatic fever 3. Reye's syndrome 4. Scarlet fever - Ans-Correct Answer: 3 RATIONALES: Research shows a correlation between the use of aspirin during chickenpox and the development of Reye's syndrome (a disorder characterized by brain and liver toxicity). Therefore, the nurse should instruct the parents to avoid administering aspirin or other products that contain salicylates and to consult the physician or pharmacist before administering any medication to a child with chickenpox. No research has found a link between aspirin use, chickenpox, and the development of Guillain-Barré syndrome, rheumatic fever, or scarlet fever. A client is to have an epidural block to relieve labor pain. The nurse anticipates that the anesthesiologist will inject the anesthetic agent into the: 1. subarachnoid space. 2. area between the subarachnoid space and the dura mater. 3. area between the dura mater and the ligamentum flavum. 4. ligamentum flavum. - Ans-Correct Answer: 3 RATIONALES: For an epidural block, the nurse should anticipate that the anesthesiologist will inject a local anesthetic agent into the epidural space, located between the dura mater and the ligamentum flavum in the lumbar region of the spinal column. When administering a spinal block, the anesthesiologist injects the anesthetic agent into the subarachnoid space. The ligamentum flavum and the area between the subarachnoid space and the dura mater are inappropriate injection sites. The physician prescribes penicillin potassium oral suspension 56 mg/kg/day in four divided doses for a client with anorexia nervosa who weighs 25 kg. The medication dispensed by the pharmacy contains a dosage strength of 125 mg/5 ml. How many milliliters of solution should the nurse administer with each dose? - Ans-Correct Answer: 14 RATIONALES: To determine the total daily dosage, set up the following proportion:25 kg/X = 1 kg/56 mg X = 1,400 mg. Next, divide the daily dosage by four doses to determine the dose to administer every 6 hours: X = 1,400 mg/4 doses X = 350 mg/dose. The adolescent should receive 350 mg every 6 hours. Lastly, calculate the volume to give for each dose by setting up this proportion: X/350 mg = 5 ml/125 mg X = 14 ml. The nurse must irrigate a gaping abdominal incision with sterile normal saline, using a piston syringe. How should the nurse proceed? 1. Irrigate continuously until the solution becomes clear or all of the solution has been used. 2. Moisten the area around the wound with normal saline after the irrigation. 3. Apply a wet-to-dry dressing to the wound after the irrigation. 4. Rapidly instill a stream of irrigating solution into the wound. - Ans-Correct Answer: 1 RATIONALES: To wash away tissue debris and drainage effectively, the nurse should irrigate the wound until the solution becomes clear or all of the solution has been used. After the irrigation, the nurse should dry the area around the wound; moistening it promotes microorganism growth and skin irritation. When the area is dry, the nurse should apply a sterile dressing, rather than awet-to-dry dressing. The nurse always should instill the irrigating solution gently; rapid or forceful instillation can damage tissues. [Show More]
