○ speculum
○ dark - field microscope
○ cystoscope
○ ureteroscope

question 26

○ neisseria meningitis
○ treponema pallidum
○ haemophilus ducreyi
○ human papilloma virus

question 27
hiv cannot be transmitted through:
○ saliva
○ blood
○ semen
○ breast milk

Explanation:

• Question 25: A speculum is a medical instrument used to hold open the walls of a bodily cavity (such as the vagina) to allow examination. A dark - field microscope is used for viewing specimens that are difficult to see with a bright - field microscope (e.g., spirochetes), a cystoscope is for examining the bladder, and a ureteroscope is for examining the ureters.
• Question 26: Genital warts are caused by the Human papilloma virus (HPV). Neisseria meningitis causes meningitis, Treponema pallidum causes syphilis, and Haemophilus ducreyi causes chancroid.
• Question 27: HIV is not transmitted through saliva in a way that causes infection (e.g., casual kissing). It is transmitted through blood (e.g., sharing needles, mother - to - child during childbirth/breastfeeding in some cases if not prevented), semen (during sexual intercourse), and breast milk (in some mother - to - child transmission cases).

Answer:

• Question 25: Speculum
• Question 26: Human papilloma virus
• Question 27: Saliva
