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.
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 C
Explanation
A. Core strengthening. While important for overall health, core strengthening is not as directly effective for osteoporosis prevention as weight-bearing exercise.
B. Aerobic exercise. Aerobic exercise is beneficial for cardiovascular health but does not have the same bone-strengthening effect as weight-bearing exercise.
C. Weight-bearing exercise. Weight-bearing exercises, such as walking, jogging, and strength training, are essential for maintaining bone density and preventing osteoporosis.
D. Muscle stretching and toning. Stretching and toning are important for flexibility and muscle health but do not significantly impact bone density compared to weight-bearing exercises.
Correct Answer is B
Explanation
A: Leaving the client alone could increase the risk of harm to herself or others and does not address the immediate need for safety and boundaries.
B: Clearly stating that undressing is unacceptable sets immediate boundaries, which is essential in managing acute behavioral situations, ensuring the client's dignity, and maintaining a professional environment.
C: Ignoring the behavior does not provide any guidance or boundaries for the client, which could lead to escalation or reinforce the inappropriate behavior.
D: While changing to less anxiety-provoking questions may be helpful, it does not directly address the behavior at hand, which could lead to further inappropriate actions or misunderstandings about acceptable behavior during the assessment.
