What should the parents of infants with a positive phenylketonuria (PKU) test be instructed to do?
Give the infant a high protein diet.
Provide the infant with a diet containing small amounts of phenylalanine.
Early introduction of cow’s milk may be necessary before 1 year of age.
Follow up with a pediatric cardiologist.
The Correct Answer is B
Choice A rationale
Giving an infant with a positive PKU test a high protein diet is not recommended. This is because phenylalanine, which cannot be broken down by individuals with PKU, is found in high-protein foods.
Choice B rationale
Parents of infants with a positive PKU test should provide the infant with a diet containing small amounts of phenylalanine. This is because while phenylalanine is harmful in large amounts to individuals with PKU, it is still an essential amino acid that the body needs in small amounts.
Choice C rationale
Early introduction of cow’s milk is not necessary before 1 year of age for infants with a positive PKU test. In fact, cow’s milk is high in phenylalanine and should be avoided.
Choice D rationale
Following up with a pediatric cardiologist is not specifically related to the dietary management of PKU. While regular medical supervision is important for children with PKU, it does not necessarily have to be with a cardiologist.

Correct Answer is A
Explanation
Choice A rationale
Oral contraceptives are often used in the treatment of PCOS to restore menstrual regularity. They do this by regulating the hormonal imbalances that cause the irregular periods seen in PCOS678910.
Choice B rationale
While oral contraceptives can indirectly lead to ovulation in some women with PCOS by regulating their menstrual cycles, they are not typically used to directly induce ovulation. Other medications, such as clomiphene or letrozole, are more commonly used for this purpose.
Choice C rationale
While insulin resistance is a common feature of PCOS, oral contraceptives are not typically used to improve insulin uptake. Other medications, such as metformin, are more commonly used for this purpose.
Choice D rationale
While oral contraceptives can help alleviate hirsutism (excessive hair growth) in women with PCOS by reducing levels of circulating androgens, this is typically considered a secondary benefit rather than the primary rationale for their use.
Correct Answer is B
Explanation
Choice A rationale
While the intrauterine device (IUD) is a highly effective form of birth control, it does not protect against sexually transmitted infections.
Choice B rationale
Checking the string of the IUD every month is a good practice to ensure that the device is still in place. This is an indication that the patient understands how to monitor the IUD correctly. Choice C rationale
The timing of IUD insertion can vary and does not necessarily need to be a week after the menstrual period. This statement does not accurately reflect understanding of the use of the IUD67.
Choice D rationale
Depending on the type of IUD, it may need to be replaced every 3-10 years, not annually. This statement does not accurately reflect understanding of the use of the IUD67.
