Correct Answer: B

Rationale: The correct answer is B: 'Avoid gluten.' Celiac disease is a condition in which the immune system reacts to gluten, a protein found in wheat, barley, and rye. Avoiding gluten is essential in managing celiac disease as it helps prevent damage to the small intestine and alleviate symptoms. Choices A, C, and D are incorrect because dairy products, high-fat foods, and foods high in sugar do not directly relate to the management of celiac disease. It is crucial to focus on eliminating gluten-containing foods to effectively control the condition.

Correct Answer: B

Rationale: The correct answer is B: Steroids. Children receiving steroids should not receive the varicella vaccine as it can increase the risk of severe infection due to the immunosuppressive effects of steroids. Insulin (Choice A) is not a medication that contraindicates varicella vaccination. Antibiotics (Choice C) and anticonvulsants (Choice D) are also not medications that would impact the decision to immunize against varicella.

Correct Answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that results in the inability to metabolize phenylalanine properly. Without proper dietary management, high levels of phenylalanine can lead to severe mental retardation and other neurological problems. Therefore, educating parents about the importance of early and consistent treatment to prevent mental retardation is crucial. Choice B is incorrect because testing for PKU is typically done shortly after birth, not immediately. Choice C is incorrect because treatment for PKU primarily involves strict dietary management to control phenylalanine intake, not lifelong medications. Choice D is incorrect because PKU is inherited in an autosomal recessive pattern, not as an autosomal dominant gene.

Correct Answer: B

Rationale: The correct answer is to 'Avoid gluten.' Celiac disease is an autoimmune disorder triggered by gluten consumption, a protein found in wheat, barley, and rye. By avoiding gluten-containing foods, individuals with celiac disease can prevent damage to their small intestine and manage their symptoms effectively. Choice A, 'Avoid dairy products,' is incorrect as dairy is not directly related to celiac disease. Choice C, 'Avoid high-fat foods,' and Choice D, 'Avoid foods high in sugar,' are incorrect as they are not primary dietary concerns in managing celiac disease. The main focus should be on eliminating gluten sources from the diet.

Correct Answer: D

Rationale: The correct answer is D. The grasp reflex and startle reflex (Moro reflex) are normal in newborns but typically disappear as the infant's nervous system matures and voluntary control develops. At around five months of age, these reflexes are replaced by voluntary movements as part of the normal developmental process. Choices A, B, and C are incorrect. Choice A suggests delaying a decision until further assessment, which is not necessary as the disappearance of these reflexes is a normal part of infant development. Choice B implies a developmental delay, which is not the case as these reflexes naturally disappear with age. Choice C recommending additional sensory stimulation is unnecessary and not the reason for the absence of these reflexes.
