Correct Answer: C

Rationale: Shigella is a bacteria sometimes found in stagnant water. Transmission of Shigella is typically oral-fecal, so good hand washing and the use of gloves are the best means of prevention when caring for a client with Shigella. The bacteria can be found in food and water contaminated by fecal material. Incidences of Shigella are reportable in many states. Choices A, B, and D are incorrect. While it is important for close contacts to be aware and practice good hygiene, testing is not routinely indicated. Shigella is not an airborne infection; it is transmitted through contaminated food or water. A one-way breathing apparatus is not necessary for caring for a patient with Shigella; standard precautions, including handwashing and gloves, are sufficient.

Correct Answer: D

Rationale: The correct answer is a five-year-old in skeletal traction. This task is within the scope of practice for an LPN and would need minimal assistance from an RN. The children with diabetic ketoacidosis, sickle cell crisis, and dehydration require close observation, good assessment skills, IVF needs, and medications that would be better managed by an RN. Reassigning the child in skeletal traction to an LPN ensures appropriate care while allowing the RN to focus on the more critical cases.

Correct Answer: A

Rationale: In an emergency situation, assessing the client's ability to speak is crucial in determining airway obstruction. If a client can speak, it indicates that the airway is patent and not completely obstructed. Choices B and C, assessing the ability to hear and oxygen saturation, are not directly indicative of an airway obstruction. Choice D, adventitious breath sounds, may be present in conditions like asthma or pneumonia but are not specific to determining an airway obstruction.

Correct Answer: C

Rationale: The document dated 2003 supersedes the previous version and should be used as a basis for care directions. The nurse should follow the 2003 version, place it in the chart, and communicate the update appropriately to ensure that the most current care directions are followed. Choices A and B are incorrect because the 1998 version is now outdated, and the nurse should not rely on it for care decisions. Choice D is incorrect because the nurse should not delay following the updated document, and seeking clarification from the unit manager can lead to avoidable delays in care.

Correct Answer: C

Rationale: The correct answer is 'hospitalized.' Elderly individuals are at a higher risk of falls, especially when they are in new environments like hospitals due to unfamiliarity with the surroundings, medications, and potential mobility challenges. Being in a hospital can disrupt their usual routines and increase the risk of falls. Choice A ('in their 80s') is not as directly related to the increased risk of falls in a hospital environment. Choice B ('living at home') is a common setting for the elderly but does not address the specific risk associated with being hospitalized. Choice D ('living on only Social Security income') is unrelated to the risk of falls based on the environment.
