Question

question 4
the majority of stis are diagnosed using:
o material swabbed from orifices
o visual examination
o sexual history
o fecal test

question 5
signs of aids include:
o weight loss, oral lesions and lymphadenopathy
o confusion, hair loss and brittle nails
o fatigue, weight gain and hypotension
o headache, vomiting and sarcopenia

question 6
what sti causes dysuria and is usually associated with bladder or kidney infections?
o balanitis
o nonspecific urethritis
o scabies
o molluscum contagiosum

Explanation:

• Question 4: For STIs (sexually transmitted infections), taking samples (swabbing) from orifices (like the genital area) is a common diagnostic method as it allows for laboratory testing of pathogens. Visual examination might miss some infections, sexual history is a part of assessment but not the main diagnostic tool, and fecal tests are not relevant for most STIs.
• Question 5: AIDS (Acquired Immunodeficiency Syndrome) due to a weakened immune system can lead to weight loss (due to poor nutrient absorption and increased metabolic rate from fighting infections), oral lesions (like thrush from fungal over - growth), and lymphadenopathy (swollen lymph nodes as the body tries to fight infections). Confusion, hair loss, brittle nails are not typical AIDS - specific signs. Weight gain is not a common sign (more likely weight loss), and headache, vomiting, sarcopenia are not the most characteristic signs compared to the first option.
• Question 6: Nonspecific Urethritis can cause dysuria (painful urination) and can be associated with bladder or kidney infections as the urethra is connected to the urinary tract. Balanitis is inflammation of the glans penis (not typically associated with bladder/kidney infections in the way described). Scabies is a skin infestation (not related to urinary symptoms in this context), and Molluscum Contagiosum is a viral skin infection (not related to the described urinary - related symptoms).

Answer:

• Question 4: material swabbed from orifices
• Question 5: Weight loss, oral lesions and lymphadenopathy
• Question 6: Nonspecific Urethritis
