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.

Explanation
Choice A rationale
Sporadic vaginal bleeding accompanied by chronic pelvic pain is not typically associated with a woman who has had multiple pregnancies and is admitted for repair of cystocele and rectocele.
Choice B rationale

Choice C rationale
Menstrual irregularities and hirsutism on the chin are not typically associated with a woman who has had multiple pregnancies and is admitted for repair of cystocele and rectocele.
Choice D rationale
Stress incontinence with a feeling of low abdominal pressure is a common symptom in women who have had multiple pregnancies and are admitted for repair of cystocele and rectocele. Multiple pregnancies can weaken the pelvic floor muscles, leading to conditions like cystocele and rectocele. Stress incontinence, where urine leaks out with increased abdominal pressure (such as when coughing, sneezing, or lifting), is a common symptom of these conditions.
Correct Answer is B
Explanation
Choice A rationale
While lying down can be part of the breast self-examination process, the arms should not be at the side. Instead, they should be raised above the head to spread the breast tissue evenly over the chest.
Choice B rationale
The finger pads of the three middle fingers are used to apply pressure to the breast during a self-exam. This allows for a thorough examination of the breast tissue for any lumps or abnormalities. This is the correct method for performing a breast self-examination.
Choice C rationale
Even if the breast feels fine, it is important to check under the arm. The lymph nodes located in this area can swell due to breast cancer.
Choice D rationale
While examining the breast, it is not necessary to work from left to right towards the ribs. The important thing is to cover the entire breast area, including the armpit.
