Correct Answer: B

Rationale: When an infant experiences intractable vomiting, it can lead to the loss of stomach acids, resulting in metabolic alkalosis. Alkalosis is characterized by elevated blood pH and can lead to serious complications. Assessing for alkalosis is essential in this scenario to monitor and manage the infant's condition. Choices A, C, and D are incorrect because in this context, the primary concern is the metabolic imbalance caused by excessive vomiting, leading to alkalosis rather than acidosis, hyperkalemia, or hypernatremia.

Correct Answer: A

Rationale: The correct answer is A: 'They may occur in minor illnesses.' Febrile seizures can occur even in minor illnesses, particularly in young children, and are often triggered by a rapid increase in body temperature. Choice B is incorrect because the cause of febrile seizures is not always readily identified. Choice C is incorrect as febrile seizures commonly occur in children between the ages of 6 months to 5 years, which includes the toddler years. Choice D is incorrect as febrile seizures are slightly more common in males than females.

Correct Answer: D

Rationale: Retractions and the use of accessory respiratory muscles can be signs of respiratory distress, which may indicate trauma such as shaken baby syndrome (SBS). Shaken baby syndrome can result in brain injury and respiratory compromise, leading to breathing difficulties. Choices A, B, and C are less likely to be associated with SBS. Birth before 32 weeks' gestation is more related to prematurity rather than SBS. The lack of stridor and adventitious breath sounds, as well as previous episodes of apnea lasting 10 to 15 seconds, are not specific indicators of SBS.

Correct Answer: A

Rationale: Checking blood glucose levels before meals and at bedtime is essential for managing type 1 diabetes mellitus. This timing helps in assessing the effectiveness of insulin therapy, making adjustments to insulin doses, and preventing hyperglycemia and hypoglycemia. Option B is incorrect because it focuses on the method of obtaining blood samples rather than the timing of monitoring. Option C is incorrect as urine test strips are not recommended for accurate blood glucose monitoring in type 1 diabetes. Option D, recognizing signs of hypoglycemia, is important but not the primary emphasis when teaching about blood glucose monitoring.

Correct Answer: A

Rationale: Infection is the greatest risk for an infant with exstrophy of the bladder due to the exposure of the bladder and surrounding tissues. The exposed bladder increases the risk of infection as it lacks the protective covering of the skin. Dehydration (Choice B) may occur but is not the greatest risk compared to infection. Urinary retention (Choice C) is less likely due to the nature of the condition. Intestinal obstruction (Choice D) is not directly associated with exstrophy of the bladder.
