The nurse is instructing a mother how to administer oral nystatin suspension prescribed to treat thrush. What will the nurse include?
Squirt the prescribed dose into the back of the mouth and have the infant swallow
Give the medication mixed with a small amount of juice in a bottle
Use a sterile applicator to swab the medication on the oral mucosa
Pour the prescribed amount into a nipple and have the infant suck the medication
The Correct Answer is C
Choice A reason: Squirting nystatin into the back of the mouth for swallowing reduces contact with oral mucosa, where Candida albicans causes thrush. Swabbing ensures prolonged antifungal exposure to infected areas, enhancing efficacy. Swallowing is less effective, as it bypasses the site of infection, making this an incorrect administration method.
Choice B reason: Mixing nystatin with juice in a bottle dilutes the medication and reduces contact time with oral mucosa, decreasing antifungal efficacy against thrush. Juice sugars may promote yeast growth. Swabbing directly applies nystatin to affected areas, making mixing with juice an incorrect and ineffective administration method.
Choice C reason: Swabbing nystatin on the oral mucosa with a sterile applicator ensures direct contact with Candida-infected areas, maximizing antifungal action. This method treats thrush by allowing prolonged exposure to the medication, reducing yeast overgrowth in the infant’s mouth, making it the correct technique for effective administration and infection resolution.
Choice D reason: Pouring nystatin into a nipple for sucking reduces contact with oral mucosa, as much of the dose may be swallowed quickly. This decreases antifungal efficacy against thrush, which requires direct mucosal application. Swabbing is preferred, making this an incorrect method for administering nystatin in infants.

Correct Answer is A
Explanation
Choice A reason: Complex carbohydrates (e.g., whole grains) and high-fiber foods provide steady glucose release, aiding glycemic control in type 1 diabetes. Fiber slows glucose absorption, reducing postprandial spikes. This supports insulin therapy, promoting stable blood sugar and preventing hypoglycemia or hyperglycemia, making it the optimal dietary measure for children.
Choice B reason: Controlling carbohydrate intake is important in type 1 diabetes, but reducing calories is not universally required, especially in growing children. Complex carbohydrates and fiber are prioritized for stable glucose levels. Calorie restriction may impair growth, making this a less appropriate dietary focus compared to complex carbohydrate emphasis.
Choice C reason: A diet low in fat is beneficial, but low complex carbohydrates are counterproductive in type 1 diabetes. Complex carbohydrates provide sustained glucose for insulin matching, supporting growth and energy needs. Low-carbohydrate diets risk hypoglycemia, making this an incorrect dietary measure for effective diabetes management in children.
Choice D reason: Obtaining most calories from proteins and fats risks ketosis and inadequate glucose for insulin therapy in type 1 diabetes. Complex carbohydrates are essential for stable blood sugar and growth. High-fat/protein diets may cause long-term cardiovascular issues, making this an inappropriate dietary focus for diabetic children.
Correct Answer is A
Explanation
Choice A reason: Pinworms (Enterobius vermicularis) are diagnosed via the Scotch tape test, performed in the early morning, when females lay eggs perianally. Tape collects eggs, visible microscopically, confirming infection. This method targets the parasite’s nocturnal egg-laying cycle, ensuring high sensitivity for detecting pinworms in children with perianal itching.
Choice B reason: Stool examination is less effective for pinworm diagnosis, as eggs are laid perianally, not in feces. Obtaining stool at sleep hours is impractical and low-yield. The Scotch tape test directly samples perianal eggs, making stool analysis an incorrect and less reliable method for confirming pinworm infection.
Choice C reason: Blood antigen levels are not used for pinworm diagnosis, as Enterobius vermicularis does not elicit a detectable systemic immune response. Diagnosis relies on visualizing eggs or worms perianally via the Scotch tape test. Blood tests are irrelevant, making this an incorrect diagnostic approach for pinworms.
Choice D reason: Seeing worms in the stool is rare in pinworm infection, as females lay eggs perianally, not in the intestinal lumen. The Scotch tape test is the standard, targeting perianal eggs. Visualizing worms is unreliable and non-specific, making this an incorrect method for diagnosing pinworms in children.
