Correct Answer: A

Rationale: When encountering an unfamiliar medication, the safest action for a nurse is to consult the medication reference book available on the unit. This resource provides accurate and detailed information about medications, including indications, dosages, side effects, and nursing considerations. Administering a medication without understanding it (choice B) can lead to medication errors and harm to the client. Asking a colleague for information (choice C) may not always provide accurate or up-to-date information. Contacting the provider (choice D) should be reserved for situations where immediate clarification is needed, but consulting the reference book is the initial step to gain knowledge and ensure safe medication administration.

Correct Answer: C

Rationale: The correct action for the nurse to take when using an open irrigation technique on a client with an indwelling urinary catheter is to subtract the amount of irrigant used from the client's urine output. This calculation helps ensure an accurate measurement of the client's actual urine output by accounting for the irrigation fluid introduced into the catheter. Placing the client in a side-lying position (Choice A) is not directly related to the irrigation procedure. Instilling a specific volume of irrigation fluid (Choice B) may vary depending on the client's condition and the healthcare provider's order. Using a 20 mL syringe for irrigation (Choice D) is a matter of equipment choice and does not directly impact the calculation of urine output in this context.

Correct Answer: A

Rationale: The correct action when inserting an NG tube is to help the client take sips of water. This helps facilitate the insertion of the tube by promoting swallowing and passage through the esophagus. Asking the client to swallow assists in guiding the tube into the stomach. Inserting the tube without asking the client to swallow may lead to incorrect placement or discomfort. Advancing the tube continuously without pausing can cause the tube to coil in the esophagus, leading to complications. Using a large-bore tube for insertion is unnecessary and may increase the risk of injury or discomfort for the client.

Correct Answer: C

Rationale: The 72-year-old recovering from surgery after a hip replacement 2 hours ago should be seen first due to the potential for immediate post-operative complications. This patient is in the immediate postoperative period and requires close monitoring for any signs of complications such as bleeding, infection, or impaired circulation. The other patients are relatively stable compared to the patient who just had surgery and therefore can wait for assessment and care without immediate risk. The 16-year-old had surgery ten hours ago, which is longer than the 72-year-old and is at a lower risk for immediate complications. The 20-year-old in skeletal traction for two weeks is stable in his current condition. The 75-year-old in skin traction before planned surgery does not require immediate attention as the surgery has not yet taken place.

Correct Answer: B

Rationale: After applying sterile gloves, the nurse should proceed to remove the sutures using sterile technique. This step ensures the safe and effective removal of sutures without introducing infection. Choice A, cleaning sutures along the incision site, would not be the next step as the primary focus is on suture removal. Inspecting the wound for signs of infection (Choice C) is important but typically follows suture removal. Documenting the removal of sutures (Choice D) is essential but usually occurs after the procedure is completed.
