Correct Answer: C

Rationale: Correct Answer: C - Fine needle aspiration does not allow grading of tumors. Rationale: 1. Fine needle aspiration (FNA) collects cells for cytology evaluation, not tissue for grading. 2. Grading requires evaluation of tissue architecture, which is not possible with FNA. 3. FNA is useful for diagnosis but not for determining tumor grade. Summary: A: Incorrect - Excisional biopsy is preferred over incisional biopsy to obtain the entire tumor for diagnosis and grading. B: Incorrect - Core needle biopsy has a lower false positive rate compared to fine needle aspiration. D: Incorrect - Core needle and incisional biopsies differ in the amount of tissue sampled and potential for false results.

Correct Answer: D

Rationale: The correct answer is D: Provide counseling to the patient regarding her options. The AGACNP's initial action should prioritize the patient's well-being and autonomy. Counseling allows the patient to understand her options, including legal, medical, and emotional support. Reporting to law enforcement (A) without the patient's consent violates her autonomy. Having the patient sign a release to go home with her husband (B) disregards the potential danger and trauma she may face. Consulting psychiatry for a psych hold (C) may not address the immediate emotional and physical needs of the patient.

Correct Answer: A

Rationale: The correct answer is A: Symptom are absent and abnormal specific laboratory results. Chemical diabetes mellitus refers to a condition where there are abnormal specific laboratory results indicating diabetes without the presence of any symptoms. This classification is based on objective data from laboratory tests rather than subjective symptoms. Choices B, C, and D are incorrect as they do not align with the definition of chemical diabetes mellitus, which focuses on laboratory results rather than symptoms, congenital abnormalities, or pregnancy outcomes.

Correct Answer: B

Rationale: The correct answer is B: Myelomeningocele. McEwen sign refers to the characteristic scalloping of the frontal bones due to pressure from the expanding brain in individuals with myelomeningocele. This sign is specific to myelomeningocele and is not associated with hydrocephalus (A), microcephaly (C), or encephalocele (D), which have different clinical manifestations and imaging findings. Myelomeningocele is a neural tube defect where the spinal cord and its coverings protrude through an opening in the spine, leading to neurological deficits and associated signs like McEwen sign.

Correct Answer: B

Rationale: The correct answer is B because the absence of any other abnormal findings suggests that Mr. Thornton is currently experiencing an anterior wall infarction. This is indicated by the localized area of myocardial necrosis due to prolonged ischemia. Option A is incorrect because ischemia would typically present with reversible changes rather than necrosis. Option C is incorrect as NSTEMI would show some abnormal findings. Option D is incorrect as STEMI would show more significant ECG changes and enzyme elevation. In summary, the absence of other abnormalities points towards an acute event like an anterior wall infarction.
