Correct Answer: C

Rationale: Feedback is an essential indicator of effective communication because it allows the sender to understand how the message was received by the receiver. It provides an opportunity to clarify any misunderstandings, confirm understanding, and ensure that the communication has been successful. Without feedback, the sender cannot be sure if their message was accurately understood or if further explanation or clarification is needed. Effective communication involves a two-way exchange, and feedback plays a crucial role in ensuring that the message is effectively transmitted and received.

Correct Answer: A

Rationale: Acute narrow-angle glaucoma is a medical emergency that requires timely intervention to reduce intraocular pressure. Acetazolamide (Diamox) is a medication commonly used to treat this condition as it works as a carbonic anhydrase inhibitor, reducing the production of aqueous humor in the eye. By reducing the production of aqueous humor, acetazolamide helps decrease intraocular pressure rapidly, which is crucial in managing acute narrow-angle glaucoma. Other options listed, such as Furosemide (Lasix), Atropine, and Urokinase (Abbokinase), are not typically used in the treatment of acute narrow-angle glaucoma.

Correct Answer: B

Rationale: Thrombotic thrombocytopenic purpura (TTP) is a rare blood disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, fever, neurological abnormalities, and renal dysfunction. The peripheral blood smear in TTP typically shows fragmented red blood cells (schistocytes) due to mechanical destruction within small blood vessels. Laboratory findings in TTP commonly include elevated lactate dehydrogenase (LDH), decreased haptoglobin (as it is consumed in the clearance of free hemoglobin), and increased indirect bilirubin due to increased red blood cell breakdown. This combination of clinical presentation and laboratory abnormalities is classic for TTP. Hemolytic uremic syndrome (HUS) may present similarly but is more commonly associated with renal dysfunction and is often triggered by infection with Shiga toxin-producing E. coli.

Correct Answer: D

Rationale: The cough of a patient with lung cancer typically starts off as dry and persistent. This is because lung cancer can irritate the airways, leading to a persistent dry cough as an early symptom. As the cancer progresses, the cough may become more productive with blood-tinged or dark yellow sputum. However, in the early stages, the cough is often dry and persistent, which can be a warning sign for healthcare providers to further investigate potential underlying issues such as lung cancer.

Correct Answer: D

Rationale: The presentation described is characteristic of a parathyroid adenoma. Parathyroid adenomas are benign neoplasms that can present as painless, well-defined nodules usually located in the lower pole of the thyroid gland or in close proximity, such as the lateral aspect of the neck above the clavicle. Fine-needle aspiration cytology of a parathyroid adenoma typically reveals polygonal cells with abundant granular cytoplasm, often referred to as chief cells. This is key in differentiating it from other conditions mentioned in the question.
