What is a common sign of a urinary tract infection (UTI) in toddlers?

Correct Answer: B

Rationale: Frequent, painful urination is a common sign of a urinary tract infection in toddlers. This symptom is often accompanied by possible fever and irritability. Excessive thirst (Choice A) is not a typical sign of a UTI in toddlers and is more commonly associated with conditions like diabetes. Increased appetite (Choice C) is not a typical symptom of a UTI in toddlers either. Skin rash (Choice D) is not a common sign of a UTI but may indicate other conditions like allergies or infections.

Correct Answer: C

Rationale: One major weakness of laboratory-based studies is that results from animal testing cannot always be applied to human beings. This limitation arises due to the inherent biological differences between animals and humans, making the generalization of findings challenging. While costs may be a concern in some cases, they do not represent a universal weakness of laboratory-based studies. Findings in such studies can be replicated to ensure validity, and experimental variables can be effectively controlled in a laboratory setting. Choice C is the correct answer because the translatability of results from animal studies to humans is a significant challenge in laboratory-based research, impacting the direct application of findings to human health and well-being.

Correct Answer: A

Rationale: When managing a child with an allergy to multiple food items, the most appropriate approach is to avoid all identified allergens. This is crucial to prevent allergic reactions and ensure the child's safety. Choice B, increasing dietary exposure to allergens, is incorrect as it can lead to severe allergic reactions. Choice C, administering daily antihistamines, may help manage symptoms but does not address the root cause, which is avoiding allergens. Choice D, restricting all food intake, is not a viable option as it can lead to malnutrition and other health issues.

Correct Answer: C

Rationale: The correct long-term complication of cleft lip and palate is faulty dentition. Individuals with cleft lip and palate may experience dental issues such as missing, extra, or misaligned teeth, which can affect speech and the aesthetic appearance of the mouth. Cognitive impairment, as mentioned in choice A, is not a typical long-term complication associated with cleft lip and palate. While altered growth and development (choice B) can be affected during early stages, it is not a prominent long-term complication. Choice D, physical abilities, is not directly related to the typical long-term complications of cleft lip and palate.

Correct Answer: B

Rationale: The correct answer is B: Risk of hyperglycemia. When a child is newly diagnosed with diabetes mellitus, one of the primary concerns is the risk of hyperglycemia, which refers to high blood glucose levels. Hyperglycemia can lead to various complications if not managed properly, making it crucial to stabilize blood glucose levels. Choices A, C, and D are incorrect because increased growth rate, risk of dehydration, and improved appetite are not primary concerns specifically associated with a new diagnosis of diabetes mellitus.

Correct Answer: A

Rationale: Proteins are indeed macronutrients as they are required by the body in larger quantities for various functions such as growth, repair, and energy production. Choice B, minerals, are micronutrients needed in smaller amounts for various physiological processes. Choices C and D, water-soluble vitamins and fat-soluble vitamins, respectively, are also micronutrients that play essential roles in the body but are not classified as macronutrients.

Correct Answer: A

Rationale: The correct answer is A: Use of steroid creams. Steroid creams are commonly used in the management of eczema to reduce inflammation and itching, thus improving the skin condition and comfort of the child. Choice B, frequent antibiotic therapy, is incorrect as antibiotics are not typically used to treat eczema unless there is a secondary bacterial infection. Choice C, a high-protein diet, is not a specific recommendation for eczema treatment. Choice D, daily baths in hot water, is not recommended for eczema care as hot water can exacerbate the condition by drying out the skin.

Correct Answer: B

Rationale: The correct answer is B: Strangulation of the hernia. Untreated inguinal hernias in children can lead to strangulation, which can result in bowel obstruction and ischemia. This is a serious complication that requires prompt medical attention. Choices A, C, and D are incorrect. Gastroenteritis is a gastrointestinal infection that is not directly related to untreated inguinal hernias. Chronic cough is not typically associated with this condition. Epistaxis refers to nosebleeds, which are not a common complication of untreated inguinal hernias in children.

Correct Answer: C

Rationale: The correct answer is C: Antibiotics. Antibiotics are the primary treatment for acute otitis media because the condition is often caused by a bacterial infection. Antihistamines (choice A) and nasal decongestants (choice B) are not the primary treatments for acute otitis media as they do not target the bacterial infection. Ear drops (choice D) are not the primary treatment for acute otitis media; antibiotics are required to treat the underlying bacterial cause.
