A patient presents with progressive hearing loss, tinnitus, and vertigo. Audiometric testing reveals sensorineural hearing loss with a "carrot-shaped" configuration. Which of the following conditions is most likely responsible for this presentation?

Correct Answer: C

Rationale: Ménière's disease is characterized by the triad of symptoms including progressive sensorineural hearing loss, tinnitus, and vertigo. The audiometric testing in Ménière's disease often shows a "carrot-shaped" configuration, which refers to low-frequency hearing loss initially and eventually spreading to involve higher frequencies. This distinctive pattern of hearing loss helps differentiate Ménière's disease from other causes like Presbycusis (age-related hearing loss) or Noise-induced hearing loss. Acoustic neuroma can present with unilateral sensorineural hearing loss but typically does not exhibit the specific "carrot-shaped" configuration seen in Ménière's disease.

Correct Answer: A

Rationale: The nurse sharing Mr. Steve's medical records with a group of visiting members of a medical mission team violates his right to expect that all communications and records pertaining to his care should be treated as confidential. Patient confidentiality is a fundamental ethical principle in healthcare that protects a patient's privacy and sensitive information. Sharing medical records without the patient's consent breaches this confidentiality and can lead to legal and ethical consequences. It is important for healthcare providers to maintain the confidentiality of patient information to uphold trust between patients and healthcare professionals.

Correct Answer: C

Rationale: The appropriate management for a conscious patient experiencing a seizure is to follow these steps:

Correct Answer: D

Rationale: The correct advice to give to the owner of the dog in case of a dog bite is to feed the dog well and observe its behavior closely. It is not necessary to give away, impound, or kill the dog immediately after a bite incident. By feeding the dog well and observing its behavior, the owner can see if there are any underlying issues that may have caused the dog to bite. Additionally, observing the dog can help the owner determine if the dog has any health issues that need to be addressed. This approach allows the owner to make an informed decision about the dog's future while ensuring the safety of others.

Correct Answer: B

Rationale: The term "collaborative" best fits the situation where a member of the Research Committee wishes to conduct a study involving an interdisciplinary team of colleagues. Collaboration refers to individuals, in this case, researchers or professionals from different disciplines coming together, sharing their expertise, and working collectively towards a common goal or project. In an interdisciplinary study, involving a collaborative approach enhances the diversity of perspectives, skills, and knowledge brought to the research, leading to more comprehensive and well-rounded outcomes. This type of study fosters cooperation, communication, and synergy among team members, thereby promoting innovation and understanding across different areas of expertise.

Correct Answer: B

Rationale: The research design being referred to in the question is an experimental design. An experimental study involves the manipulation of an independent variable, which is the intervention in this case, to determine its effect on a dependent variable. "Blinding" in research refers to the practice of withholding information about the intervention from certain individuals involved in the study, such as researchers, participants, or outcome assessors. Blinding is commonly used in experimental studies to reduce bias and ensure the integrity of the study results. This combination of intervention and blinding is a hallmark of experimental research designs.

Correct Answer: A

Rationale: The clinical presentation of recurrent fever, sore throat, cervical lymphadenopathy, leukocytosis with atypical lymphocytes, and positive heterophile antibody test (Monospot test) is highly indicative of infectious mononucleosis caused by the Epstein-Barr virus (EBV). EBV is a member of the herpesvirus family and is a common cause of infectious mononucleosis. The atypical lymphocytes seen on peripheral blood smear are reactive T lymphocytes responding to the EBV infection. The Monospot test detects heterophile antibodies produced in response to EBV infection.

Correct Answer: B

Rationale: Pelvic inflammatory disease (PID) is the most likely cause of the symptoms described in the pregnant woman. PID is an infection of the female reproductive organs, typically caused by sexually transmitted bacteria like Chlamydia or Gonorrhea. The classic presentation includes lower abdominal pain, fever, vaginal discharge, cervical motion tenderness, and bilateral adnexal tenderness on examination. This condition can lead to serious complications if not promptly treated, including infertility, ectopic pregnancy, and chronic pelvic pain. Therefore, it is crucial to diagnose and manage PID promptly, especially in pregnant women, to prevent adverse outcomes.
