Oral Pathology
Explanation: It is caused by a gram-negative fungus: This statement
is not true. Thrush is caused by Candida albicans,
which is a yeast (fungus) but not a gram-negative organism. In fact, fungi
are not classified as gram-positive or gram-negative in the same way that
bacteria are. Candida is a eukaryotic organism and does not fit
into the gram classification system. It is characterized by a plaque of proliferating epithelial and
other cells: This statement is true. Thrush
presents as white patches or plaques in the oral cavity, which consist of
fungal elements, dead epithelial cells, and inflammatory cells. It is a complication of immunosuppression or systemic disease:
This statement is true. Thrush is commonly seen in
individuals who are immunocompromised, such as those with HIV/AIDS, cancer
patients undergoing chemotherapy, or individuals on long-term corticosteroid
therapy. It can affect neonates in an epidemic fashion: This
statement is true. Thrush can indeed affect neonates,
particularly those born to mothers with vaginal candidiasis, and outbreaks
can occur in neonatal intensive care units.

Physiology
Answer: 4) Increase in heart rate and increase in stroke volume
Explanation: Thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3), enhance the effects of catecholamines on the cardiovascular system, leading to increased heart rate and stroke volume. This results in a higher cardiac output, which is essential for meeting the increased metabolic demands during stress or exercise.

Oral SurgeryThe reddish patch of median rhomboid glossitis lacks filiform papillae, which are the most numerous papillae covering the anterior two-thirds of the tongue's dorsal surface. These papillae are highly keratinized and are responsible for the tongue's normal white-pink appearance. The absence of these keratinized papillae makes the affected area appear redder and smoother, standing out distinctly from the surrounding normal tongue tissue.

1) Yellow: This is often used for isolation wastes, such as those from
patients with a communicable disease or from the isolation ward. It may also be
used for trace chemotherapy waste.
2) Black: Typically used for non-infectious waste that is not recyclable, such
as general waste from hospital areas not directly involved in patient care.
3) Green: This is commonly used for anatomical waste, which includes human
tissues, organs, body parts, and animal carcasses used in research or treatment.
4) Red: As mentioned, is used for infectious or biohazardous waste that poses a
risk of infection or disease transmission.
