Correct Answer: A

Rationale: Signs such as using tissues to doorknobs suggest that the patient is unconsciously controlling unacceptable impulses or feelings. This behavior falls under the category of defense mechanisms, specifically displacement, where the individual redirects their emotions from a threatening target to a safer one. In this case, the patient may be experiencing anxiety or fear related to contamination or germs, leading them to use tissues to avoid touching doorknobs directly. It is a way for the patient to manage their underlying emotions, albeit unconsciously, through this compulsive behavior.

Correct Answer: A

Rationale: The patient's presentation of recurrent episodes of postnasal drip, chronic cough, halitosis, and foul-smelling, yellowish discharge from the middle meatus is highly suggestive of chronic rhinosinusitis. The presence of nasal polyps further supports this diagnosis. Chronic rhinosinusitis with nasal polyps is characterized by inflammation of the paranasal sinuses, leading to symptoms such as nasal congestion, postnasal drip, cough, and a reduced sense of smell. The yellowish discharge and foul odor are typical findings in cases of chronic rhinosinusitis with secondary bacterial infection. Nasal endoscopy may reveal edematous nasal mucosa and polyps obstructing the middle meatus, contributing to the symptoms described by the patient. Management typically involves a combination of medical therapies such as intranasal corticosteroids, saline irrigation, and antibiotics, and in some cases, surgical intervention

Correct Answer: A

Rationale: Osteoporosis is known as a "silent disease" because it develops slowly over time without any symptoms. Many people with osteoporosis are unaware of their condition until they experience a fracture. The loss of bone density and strength in osteoporosis occurs without any obvious warning signs, making it important for individuals at risk to undergo bone density testing to identify the condition early and prevent further bone loss.

Correct Answer: B

Rationale: The gallbladder is the structure responsible for storing and concentrating bile produced by the liver until it is needed for digestion. Bile is a digestive fluid that helps in the breakdown of fats during the digestive process. When food containing fats enters the small intestine, the gallbladder contracts and releases bile into the small intestine to aid in the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, storing it until it is needed for digestion.

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.
