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 D

Explanation

A. Administer aspirin to prevent further clot formation and platelet clumping. While aspirin may be indicated in the treatment of ischemic stroke, it is not the immediate priority. The client requires further assessment and diagnostic evaluation before initiating specific treatments.
B. Raise the head of the bed to 30 degrees keeping head and neck in neutral alignment.
Positioning the client is important for maintaining airway patency, but it is not the priority when assessing and managing acute stroke. Immediate interventions to address potential thrombolytic therapy take precedence.
C. Begin continuous observation for transient episodes of neurologic dysfunction. Continuous observation is important for monitoring the client's neurological status, but it is not the first action to take. The client requires urgent diagnostic imaging to confirm the diagnosis and
determine eligibility for thrombolytic therapy.

D. Start two large bore IV catheters and review inclusion criteria for IV fibrinolytic therapy. This is the priority action. IV access is crucial for administering medications and fluids, and reviewing the inclusion criteria for IV fibrinolytic therapy is essential to determine if the client meets the
criteria for this time-sensitive intervention.

Correct Answer is ["0.8"]

Explanation

Convert the client's weight from pounds to kilograms (kg).
Calculate the enoxaparin sodium dosage per day based on the client's weight and the prescribed dosage of 1.5 mg/kg/day.
Divide the enoxaparin sodium dosage by the concentration of the medication in the prefilled syringe (120 mg/0.8 mL) to determine the volume to administer.

Step 1: Convert weight from pounds to kilograms

- Client's weight in kg = Client's weight in pounds / 2.2
- Client's weight in kg = 176 pounds / 2.2 = 80 kg

Step 2: Calculate enoxaparin sodium dosage per day

- Enoxaparin sodium dosage (mg/day) = Client's weight (kg) × Prescribed dosage (mg/kg/day)
- Enoxaparin sodium dosage (mg/day) = 80 kg × 1.5 mg/kg/day = 120 mg/day

Step 3: Determine the volume to administer

- Volume to administer (mL) = Enoxaparin sodium dosage (mg/day) / Medication concentration (mg/mL)
- Volume to administer (mL) = 120 mg/day / (120 mg/0.8 mL) = 0.8 mL

Therefore, the nurse should administer 0.8 mL of enoxaparin sodium to the client.
