Correct Answer: A

Rationale: The least appropriate assignment for a nursing assistant would be assisting a client with dysphagia in eating. This task requires specialized skills and knowledge to prevent complications such as choking and aspiration. Ambulating a client with Parkinson's disease, providing hygiene to a client with dementia, and assisting a client with an above-the-knee amputation in showering are tasks that a nursing assistant can safely perform without significant risk of complications. Assisting a client with dysphagia in eating involves higher risks and requires specific training, making it the least appropriate choice for a nursing assistant.

Correct Answer: C

Rationale: The correct answer is to assess the nail beds and the tissue surrounding the nails. This assessment is crucial to identify abnormal discoloration, lesions, paronychia, dryness, breaks in the skin, pressure areas, or any other unusual appearances. Choice A is incorrect as a full-body assessment is broader and not specific to nail and foot care. Choice B is incorrect as lab work is not directly related to nail and foot assessments. Choice D is incorrect as it focuses only on foot corns and calluses, neglecting other important aspects of nail and foot care.

Correct Answer: A

Rationale: The correct answer is to insert the enema tube 4 inches. Enema tubing must be passed beyond the internal sphincter, which is typically around 4 inches in an adult. Inserting the tube only 2 inches is not far enough to reach this point. On the other hand, inserting the tube 6 or 8 inches is too far and might cause trauma to the bowel, which is unnecessary for a flatus-reducing enema. Therefore, the correct insertion depth of the enema tube is crucial to ensure effectiveness and safety in providing the intended treatment.

Correct Answer: A

Rationale: When administering an intramuscular injection in the deltoid muscle, the correct technique involves administering the injection 2 inches below the acromion process, which is the bony structure on top of the shoulder blade. This location ensures safe and effective administration. Administering the injection in the thigh (vastus lateralis or rectus femoris muscle) is not appropriate for a deltoid injection as the deltoid muscle is located in the upper arm. The Sims position is not the correct position for a deltoid muscle injection. While positioning the client with the deltoid muscle exposed allows for proper access and visualization, the critical aspect for a correct deltoid injection is the accurate injection site, 2 inches below the acromion process.

Correct Answer: D

Rationale: The nurse's primary responsibility after assigning tasks is to follow up with each staff member regarding the task's performance and outcomes. This ensures accountability and quality care delivery. Allowing staff members to make judgments independently can compromise patient safety if they lack the necessary knowledge or experience. While documenting task completion is important, it should follow the follow-up to assess outcomes. Assigning incomplete tasks to the next shift is not ideal as it may result in unmet patient needs and increased workload for the next shift.
