The nurse is collecting a heelstick blood specimen for a neonatal screen, which includes thyroxine (T4) and thyroid stimulating hormone (TSH) levels, prior to the discharge of a 2-day- old client. When the parents ask why these tests are being conducted, which explanation should the nurse provide?

These laboratory values will provide data to anticipate delays in growth and development.

This is a routine blood test required by law to screen for metabolic deficiencies.

Dosages for thyroid replacement therapy will be determined by this test.

This technique is used for early detection of intellectual disabilities.

Answer and Explanation

The Correct Answer is B

A. These laboratory values will provide data to anticipate delays in growth and development.
While abnormal results from these tests could indicate potential developmental issues, the primary purpose of the screening is not to predict delays in growth and development but to identify metabolic deficiencies.

B. This is a routine blood test required by law to screen for metabolic deficiencies.
This is the correct answer. Neonatal screening, including tests for T4 and TSH, is a standard practice mandated by law in many regions to identify metabolic deficiencies such as congenital hypothyroidism early on, ensuring prompt treatment to prevent serious health issues.

C. Dosages for thyroid replacement therapy will be determined by this test.
This explanation might be applicable if a deficiency is detected, but it is not the primary reason for conducting the initial screening. The primary purpose is to identify whether there is a need for treatment.

D. This technique is used for early detection of intellectual disabilities.
Although untreated metabolic deficiencies like congenital hypothyroidism can lead to intellectual disabilities, the primary goal of the screening is to detect and treat these deficiencies before they can cause such problems.

Correct Answer is ["1.8"]

Explanation

Steps to solve:

Convert the client's weight from pounds to kilograms:
- Weight (kg) = Weight (pounds) / 2.20462
- Weight (kg) = 132 pounds / 2.20462 ≈ 59.87 kg (round to nearest tenth for medication calculation)
Calculate the total dantrolene dosage based on the prescribed dosage per kilogram:

- Dosage (mg) = Weight (kg) x Dosage per kg
- Dosage (mg) = 59.87 kg x 1.5 mg/kg
- Dosage (mg) ≈ 89.8 (round to nearest tenth)

Determine the concentration of dantrolene after reconstitution:

Concentration = 50 mg/mL (given on the vial label)

Calculate the volume of the solution to administer:

- Volume (mL) = Dosage (mg) / Concentration (mg/mL)
- Volume (mL) = 89.8 mg / 50 mg/mL
- Volume (mL) ≈ 1.79 mL (round to one decimal place)= 1.8mL

A. Provide a list of alternative activities that are less likely to cause the child to experience fatigue. B. Suggest that the child be encouraged to participate in a team sport to encourage socialization. C. Explain that their child is too young to understand the risks associated with swimming. D. Encourage the parents to allow the child to continue attending swimming lessons with supervision.

Correct Answer is D

Explanation

- A: Providing a list of alternative activities may reduce fatigue, but it does not consider the child's interest in swimming, which can be therapeutic and enjoyable for children with Duchenne muscular dystrophy.
- B: While team sports can be good for socialization, they may not be suitable for a child with Duchenne muscular dystrophy due to the progressive muscle weakness associated with the condition, which could lead to increased risk of injury.
- C: At the age of 6, children are capable of understanding basic risks, and it is important to communicate with them appropriately rather than assuming they are too young. Moreover, swimming can be adapted to be safe for children with physical limitations.
- D: Swimming is an excellent activity for children with Duchenne muscular dystrophy because it is low-impact and can help maintain muscle strength and function. With proper supervision and precautions, the risks can be managed, making it a suitable activity for the child to continue.
