Correct Answer: A

Rationale: Tinea Capitis, also known as scalp ringworm, is primarily transmitted through direct contact with infected personal items such as towels, combs, or hats. Exposure to worm eggs through bare feet is not a mode of transmission for Tinea Capitis. This is more commonly associated with a different type of parasitic infection known as hookworm. Sitting on worm eggs is not a mode of transmission for Tinea Capitis. This is a misconception and there is no scientific evidence to support this claim. Airborne droplet transmission is not a mode of transmission for Tinea Capitis. Tinea Capitis is caused by a type of fungus, not a virus or bacteria, and it does not spread through the air via droplets.

Correct Answer: B

Rationale: Shingles, also known as herpes zoster, is a viral infection that causes a painful rash and is caused by the varicella-zoster virus, the same virus that causes chickenpox. Tinea pedis is a foot infection due to a dermatophyte fungus. It is the most common dermatophyte infection and is particularly prevalent in hot, tropical, urban environments. Interdigital involvement is most commonly seen (this presentation is also known as athlete's foot, although some people use the term for any kind of tinea pedis). Fever blister, also known as cold sores, are caused by the herpes simplex virus. They are small, fluid-filled blisters that develop on the lips or around the mouth. Pinworms are a type of parasite that lives in the lower intestine of humans. They are tiny, narrow worms. They are white and less than a half-inch long.

Correct Answer: A

Rationale: A urine specific gravity of 1.034 is higher than the normal range (1.002-1.030), indicating that the urine is more concentrated due to a lack of hydration. A bounding pulse is not typically associated with dehydration. Dehydration more commonly results in a weak, rapid pulse. A blood pressure reading of 46/94 mm Hg is not indicative of dehydration. Dehydration often leads to low blood pressure. Distended neck veins are not a typical sign of dehydration. Dehydration can lead to decreased blood volume, which would not cause distension of the neck veins.

Correct Answer: C

Rationale:
Step 1: Convert the child's weight from lbs to kg. Since 1 lb is approximately 0.45 kg, a child who weighs 6 lbs weighs approximately 2.72 kg (6 lbs × 0.45 =2.72 kg).
Step 2: Calculate the total daily dose of Ampicillin. The total daily dose is 50 mg/kg/day, so for a child who weighs 2.72 kg, the total daily dose would be approximately 136 mg (50 mg/kg/day × 2.72 kg = 136 mg/day).
Step 3: Since the total daily dose is divided into q hr doses (4 doses per day), each dose would be approximately 34 mg (136 mg/day ÷ 4 doses/day = 34 mg/dose). So, the child will receive approximately 34 mg of Ampicillin with each dose.

Correct Answer: B

Rationale: Hypotension, or low blood pressure, is not typically associated with nephrotic syndrome. In fact, some patients with nephrotic syndrome may experience high blood pressure. Generalized edema, or swelling, is a common characteristic of nephrotic syndrome. It occurs due to the loss of proteins in the urine, which leads to a decrease in the amount of protein in the blood. This decrease in blood protein levels causes fluid to move from the blood vessels into the tissues, leading to swelling. Increased urinary output is not typically associated with nephrotic syndrome. In fact, some patients may experience decreased urine output. Bright red blood in the urine is not a typical symptom of nephrotic syndrome. Hematuria, or blood in the urine, when present in nephrotic syndrome, is usually microscopic and not visible to the naked eye.
