2) Thigh
3) Scrotum
4) All of the above
Oral medicine
Answer: 4
Varicose veins are characterized by twisted, swollen veins that often
appear blue or purple. Common signs and symptoms include aching or heavy
legs, burning or throbbing sensations, muscle cramps, swelling in the lower
legs, and skin changes such as color alterations or sores
Visible Changes:
Twisted, swollen veins that are often blue or dark purple.
Bulging veins that may appear just below the skin surface.
Physical Sensations:
Aching or heavy feeling in the legs.
Burning, throbbing, or cramping sensations, particularly in the
calves.
Swelling in the lower legs and ankles.
Skin Changes:
Color changes in the skin, which may appear red or brown.
Development of sores or ulcers on the skin that do not heal easily.
Scaly or irritated skin that may crack easily.
Other Symptoms:
Restless legs syndrome, which can cause discomfort and an urge to
move the legs.
Pain in the legs or calves after prolonged sitting or standing.
Complications of Varicose Veins
Severe Symptoms:
Increased leg swelling and pain, especially after long periods of
inactivity.
Risk of developing deep vein thrombosis (DVT), which can lead to
serious complications if blood clots form.
Skin Conditions:
Lipodermatosclerosis, a condition that causes inflammation and
hardening of the skin.
Venous ulcers, which are painful sores that can develop due to poor
circulation.
A 2-year-old child is brought to the emergency department with fever and seizures. The child's mother reports that the child has been vomiting and has had diarrhea for the past 24 hours. What is the most likely diagnosis?
(1) Diabetic ketoacidosis
(2) Meningitis
(3) Sepsis
(4) Gastroenteritis
The combination of fever, vomiting, and diarrhea with seizures in a young child is more indicative of gastroenteritis, which can cause dehydration and electrolyte imbalances leading to seizures, rather than the other options listed.
A 65-year-old male with a history of hypertension is admitted for an acute exacerbation of chronic obstructive pulmonary disease (COPD). His current medication includes metoprolol. Which of the following is a possible adverse effect of metoprolol that could be relevant to his condition?
(1) Bronchospasm
(2) Peripheral edema
(3) Bradycardia
(4) Tachycardia
Metoprolol is a beta-blocker, which can cause bronchospasm as a side effect, particularly in patients with a history of respiratory conditions like asthma or COPD. It is important to monitor patients with respiratory diseases closely for signs of bronchospasm when prescribing beta-blockers.
Wound contraction can be most effectively minimized by
1) Split skin graft
2) Full thickness grafting
3) Allowing secondary granulation
4) Dressing with placenta
Oral medicine
Answer: 2
Full thickness grafting is effective in minimizing wound contraction because it provides a more stable and vascularized tissue bed for healing
What is the primary risk factor for deep vein thrombosis (DVT) in hospitalized patients?
1) Age over 65
2) Prolonged immobilization
3) Obesity
4) Cancer
Prolonged immobilization, such as during hospitalization or after surgery, is a significant risk factor for the development of DVT. Other risk factors include age over 65, obesity, and cancer, but among hospitalized patients, immobilization is the most common precipitating factor for venous thrombosis.
What condition is NOT associated with osteoporosis?
1) Hypogonadism
2) Hyperthyroidism
3) Fluorosis
4) Hyperparathyroidism
Fluorosis is associated with osteosclerosis, not osteoporosis. It leads to increased bone density due to excessive deposition of fluoride.
Which is a non-absorbable suture
1) Polypropylene
2) Polyglycollic acid
3) Vicryl
4) Collagen
Oral medicine
Answer: 1
1. Polypropylene: This is a synthetic, non-absorbable suture material known
for its strength and resistance to infection. It is commonly used in oral
surgery and dental procedures due to its non-reactive nature with tissues.
2. Polyglycollic acid: Polyglycollic acid is an absorbable suture material that
is broken down by hydrolysis.
3. Vicryl: Vicryl is a synthetic, absorbable suture material that is commonly
used in dentistry due to its good handling properties and tissue reactivity
profile.
4. Collagen: Collagen is a natural, absorbable suture material derived from
animal sources. It is biocompatible but not as strong as non-absorbable
materials and is absorbed by the body over time.
The drug of choice for the treatment of tuberculous meningitis is:
1) Rifampicin
2) Isoniazid
3) Streptomycin
4) Gentamicin
Rifampicin is a first-line drug for the treatment of tuberculous meningitis. It has excellent penetration into the cerebrospinal fluid and is bactericidal. Isoniazid and ethambutol are also commonly used as part of a multi-drug regimen, but rifampicin is particularly important due to its ability to cross the blood-brain barrier effectively and its rapid bactericidal activity against Mycobacterium tuberculosis.
