The newborn diagnosed with phenylketonuria (PKU) will require long-term follow-up to assess for the development of:

Choice A reason:

This is a normal WBC for a newborn. According to MedlinePlus, the normal amount of white blood cells (WBCs) found in the bloodstream of a newborn infant is between 4,500 and 10,000 per microliter of blood. The reference ranges for WBC count established by Mayo Medical Laboratories for infants from birth to 2 years are as follows:.

• Birth: 9.0 to 30.0 x 10 9 /L.

• 1 to 7 days: 9.4 to 34.0 x 10 9 /L.

• 8 to 14 days: 5.0 to 21.0 x 10 9 /L.

• 15 days to 1 month: 5.0 to 20.0 x 10 9 /L.

• 2 to 5 months: 5.0 to 15.0 x 10 9 /L. Therefore, a newborn's WBC of 15,000 is within the normal range and does not indicate any problem.

Choice B reason:

You must call the doctor. This is not a correct answer because there is no need to call the doctor for a normal WBC in a newborn. Calling the doctor unnecessarily may cause anxiety and a waste of time and resources.

Choice C reason:

This indicates a severe infection. This is not a correct answer because a WBC of 15,000 does not necessarily indicate a severe infection in a newborn. A high WBC, also called leukocytosis, may be related to infection, but it can also be caused by other factors such as stress, inflammation, trauma, medication, or blood disorders. Moreover, the type and severity of infection can be better assessed by looking at the differential count of the different types of white blood cells (neutrophils, eosinophils, basophils, monocytes, and lymphocytes) and other signs and symptoms.

Choice D reason:

This is a lab error. This is not a correct answer because a WBC of 15,000 is not likely to be a lab error in a newborn. Lab errors can occur due to improper collection, handling, or analysis of blood samples, but they are rare and usually detected by quality control measures. A WBC of 15,000 is within the normal range for a newborn and does not require repeating the test unless there is a strong suspicion of an error or an inconsistency with other results or clinical findings.

Choice A reason:

Swimming is one of the best exercises for pregnant women because it provides moderate aerobic conditioning with minimal stress on your joints. It also supports your increased weight and helps you stay cool and comfortable.

Choice B reason:

Scuba diving is not a safe exercise for pregnant women because it poses a high risk of injury to the baby. The baby has no protection against decompression sickness and gas embolism, which are caused by changes in pressure underwater.

Choice C reason:

Walking is a great exercise for beginners and can be done throughout pregnancy. It improves your cardiovascular fitness, strengthens your muscles and bones, and helps prevent excessive weight gain and gestational diabetes.

Choice D reason:

Yoga can be beneficial for pregnant women as it can improve flexibility, balance, posture, breathing and relaxation. It can also reduce stress, anxiety and back pain. However, some yoga poses may not be suitable for pregnancy, so it is advisable to join a prenatal yoga class or consult a qualified instructor.

Choice E reason:

Snow skiing is not recommended for pregnant women because it involves a high risk of falling and affecting your balance. Falls can cause damage to your baby or placenta, especially in the second and third trimesters.
