The client with diabetes is preparing for discharge. During discharge teaching, the nurse assesses the client's ability to care for himself. Which statement made by the client would indicate a need for follow-up after discharge?

Correct Answer: B

Rationale: A client with diabetes who has trouble seeing would require follow-up after discharge. The lack of visual acuity for the client preparing and injecting insulin might require help. Answers A, C, and D will not prevent the client from being able to care for himself and are incorrect. Living alone (Choice A) does not necessarily indicate a need for follow-up unless there are specific concerns. Having a cat at home (Choice C) and driving to the doctor (Choice D) are not direct indicators of the client's ability to care for himself.

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: 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: Carbamazepine (Tegretol) can suppress the bone marrow, leading to a decrease in the white blood cell count. A laboratory value of WBC 2,000 per cubic millimeter indicates a serious side effect of the drug. Choices A and D are within normal limits, while choice B is at the lower limit of normal. Therefore, choices A, B, and D are incorrect.

Correct Answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.
