A neonate born with ambiguous genitalia is diagnosed with congenital adrenal hyperplasia (CAH). This is an autosomal recessive disorder which causes an overproduction of:
Androgens
Vitamin K
Gonadotropin
Vitamin D
The Correct Answer is A
The correct answer is a) Androgens.
Choice A reason:
Congenital adrenal hyperplasia (CAH) is a group of genetic disorders affecting the adrenal glands, which are responsible for producing vital hormones such as cortisol, aldosterone, and androgens. In CAH, there is a deficiency of the enzyme 21-hydroxylase, which is crucial for the synthesis of cortisol and aldosterone. As a result, the adrenal glands overproduce androgens, leading to symptoms such as ambiguous genitalia in newborns, early puberty, and rapid growth. Androgens are male sex hormones, including testosterone, which play a significant role in the development of male characteristics.
Choice B reason:
Vitamin K is a fat-soluble vitamin essential for blood clotting and bone health. It is not related to the overproduction of hormones in congenital adrenal hyperplasia. Vitamin K deficiency can lead to bleeding disorders, but it does not cause the symptoms associated with CAH, such as ambiguous genitalia or early puberty. Therefore, this choice is incorrect.
Choice C reason:
Gonadotropins are hormones produced by the pituitary gland that stimulate the gonads (ovaries and testes) to produce sex hormones and gametes (eggs and sperm). While gonadotropins play a role in sexual development and reproduction, they are not overproduced in congenital adrenal hyperplasia. The primary issue in CAH is the overproduction of androgens due to enzyme deficiencies in the adrenal glands. Therefore, this choice is incorrect.
Choice D reason:
Vitamin D is a fat-soluble vitamin essential for calcium absorption and bone health. It is not related to the overproduction of hormones in congenital adrenal hyperplasia. Vitamin D deficiency can lead to bone disorders such as rickets in children and osteomalacia in adults, but it does not cause the symptoms associated with CAH. Therefore, this choice is incorrect.

Correct Answer is B
Explanation
Choice A reason:
Assessing fluid intake is important in managing dehydration, but it is not the most critical assessment before initiating an IV infusion containing potassium chloride (KCL). Fluid intake provides information about the child’s hydration status but does not directly indicate kidney function. Since potassium can cause hyperkalemia if not properly excreted, monitoring urine output is more crucial.
Choice B reason:
Urine output is the most important assessment before initiating an IV infusion containing potassium chloride (KCL). This is because adequate urine output indicates that the kidneys are functioning properly and can excrete excess potassium. Administering potassium chloride without ensuring proper kidney function can lead to hyperkalemia, a potentially life-threatening condition. Therefore, checking urine output is essential to prevent complications.
Choice C reason:
Capillary refill is a useful assessment for evaluating peripheral perfusion and hydration status. However, it does not provide direct information about kidney function or the body’s ability to excrete potassium. While capillary refill can be part of the overall assessment, it is not the most critical factor before administering an IV infusion with potassium chloride.
Choice D reason:
The number of stools is relevant in assessing dehydration, especially if the child has been experiencing diarrhea. However, like fluid intake, it does not directly indicate kidney function. Monitoring urine output is more important before administering potassium chloride to ensure the kidneys can handle the additional potassium load.
Correct Answer is ["A","B","C"]
Explanation
The correct answers are a) Use a straw to administer the medication, b) Give the medication with vitamin C, and c) It is best to give the medication with food.
Choice A reason:
Using a straw to administer ferrous sulfate is recommended to prevent staining of the teeth. Ferrous sulfate, especially in liquid form, can cause discoloration of the teeth if it comes into direct contact with them. By using a straw, the medication bypasses the teeth, reducing the risk of staining.
Choice B reason:
Giving ferrous sulfate with vitamin C is beneficial because vitamin C enhances the absorption of iron. Vitamin C (ascorbic acid) helps convert iron into a form that is more easily absorbed by the body. Therefore, administering ferrous sulfate with a source of vitamin C, such as orange juice, can improve its effectiveness.
Choice C reason:
It is best to give ferrous sulfate with food to reduce gastrointestinal side effects. While iron is best absorbed on an empty stomach, it can cause stomach upset, nausea, and constipation. Taking the medication with food can help mitigate these side effects, making it more tolerable for the child.
Choice D reason:
Giving ferrous sulfate with milk is not recommended. Dairy products, including milk, can interfere with the absorption of iron. Calcium in milk binds with iron, reducing its bioavailability and effectiveness. Therefore, it is best to avoid giving ferrous sulfate with milk or other dairy products.
