Rationale: Lactulose is administered to the client with cirrhosis to lower ammonia levels, as it works by acidifying the colon, trapping ammonia for elimination in the stool. Choices A, B, and D are incorrect because Lactulose does not have an effect on blood glucose, uric acid, or creatinine levels. Therefore, the correct answer is to lower the ammonia level.

Correct Answer: C

Rationale: The least helpful question in obtaining information regarding intussusception is "Describe his usual diet."? This question is least relevant to the specific symptoms and presentation of intussusception. Choices A, B, and D are more directly related to symptoms commonly associated with intussusception and can provide important diagnostic clues. Asking about pain, vomit appearance, and changes in abdominal size can help in assessing the severity and progression of the condition, making them more crucial questions to ask in this scenario. Pain is a cardinal symptom of intussusception, changes in vomit appearance may indicate gastrointestinal issues, and alterations in abdominal size can signify the presence of a mass or obstruction, all of which are pertinent in diagnosing and managing intussusception.

Correct Answer: B

Rationale: The correct answer is to inform the client that portions of the renal biopsy procedure can cause pain or discomfort, particularly when the sample is being withdrawn. This prepares the client for any unpleasant sensations during the procedure. Answer A is incorrect because the client will be positioned lying down, not sitting up, during the exam, so this information is not relevant to include in the teaching session. Answer C is incorrect as anesthesia is commonly used to numb the area for a renal biopsy, reducing pain, so the client can expect to receive anesthesia. Answer D is incorrect because clients are usually instructed to refrain from eating or drinking for a period before the procedure to prevent any complications during the biopsy, not simply before the study.

Correct Answer: A

Rationale: The client with Alzheimer's disease is the most stable among the clients listed and can be appropriately assigned to the nursing assistant. Nursing assistants are capable of providing care such as feeding and assisting with activities of daily living for individuals with Alzheimer's disease. Clients with pneumonia, appendicitis, and thrombophlebitis are less stable and necessitate the expertise of a registered nurse for accurate assessment and interventions. Therefore, the nursing assistant can effectively care for the client with Alzheimer's disease while ensuring that the other clients receive the necessary level of care from a registered nurse.

Correct Answer: D

Rationale: The correct answer is D: Squeezing a ball. The first exercise that should be done by a client with a mastectomy is squeezing a ball. This helps in regaining strength and mobility in the affected area. Choices A, B, and C are incorrect as they are not typically the initial exercises recommended post-mastectomy. Walking the hand up the wall, sweeping the floor, and combing hair are activities that may be introduced later in the rehabilitation process.
