Correct Answer: C

Rationale: When a client is receiving total parenteral nutrition (TPN), monitoring blood glucose levels is crucial as TPN solutions contain high amounts of glucose. This monitoring helps prevent hyperglycemia or hypoglycemia. Evaluating hemoglobin (choice A) is not directly related to TPN administration. Creatinine (choice B) is more relevant for assessing kidney function. White blood cell count (choice D) is important for evaluating immune function and infection, but not specifically tied to TPN administration.

Correct Answer: D

Rationale: Ewing's sarcoma is a type of bone cancer that primarily affects the bones. Therefore, bone pain would be an expected symptom due to this tumor's location. Hemiplegia, which refers to paralysis on one side of the body, Aphasia, a language disorder, and Nausea are not typical symptoms of Ewing's sarcoma. While Nausea is a common symptom in various conditions, it is not specific to bone cancer like Ewing's sarcoma. Therefore, Bone pain is the most likely symptom associated with Ewing's sarcoma.

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.

Correct Answer: B

Rationale: The correct answer is B: Denial. The client displaying denial refuses to acknowledge the reality of having a myocardial infarction. Rationalization (choice A) involves making excuses for behavior, not denying a condition. Projection (choice C) is attributing one's thoughts or feelings to others, not denying an illness. Conversion reaction (choice D) is converting psychological distress into physical symptoms, which is not evident in this scenario. Therefore, denial is the defense mechanism being used in this situation.

Correct Answer: C

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.
