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 ["A","C","G"]
Explanation
A. Administer oxygen 5 L/minute via simple face mask: Oxygen administration is a priority intervention to improve oxygenation and address the client's low oxygen saturation of 82%.
Hypoxemia can lead to tissue hypoxia and further compromise the client's condition. Therefore, administering oxygen should be the first action taken to ensure an adequate oxygen supply to vital organs.
B. Bacitracin applied topically to lacerations every 12 hours: While wound care is important, administering oxygen and establishing IV access take precedence over topical
treatment. Oxygenation and fluid resuscitation are critical in the immediate management of a trauma patient to ensure adequate tissue perfusion and oxygen delivery.
C. Place 2 large bore peripheral IV's: Establishing IV access is essential for administering medications and fluids rapidly. This is particularly important in this scenario where the client may require immediate fluid resuscitation due to hypotension (blood pressure of 83/41 mm Hg).
Large bore IV access allows for rapid infusion of fluids and medications to stabilize the client's hemodynamic status.
D. X-ray of the right arm and cervical spine: While diagnostic imaging is important for assessing injuries, it is not as urgent as administering oxygen and establishing IV access. Oxygenation and fluid resuscitation are higher priorities to stabilize the client's condition before proceeding with diagnostic tests.
E. Computed tomography scan of the brain: While a CT scan of the brain is essential for assessing potential head injuries, the immediate focus should be on stabilizing the client's oxygenation and hemodynamic status. Administering oxygen and fluids take precedence over diagnostic imaging to address the client's hypoxemia and hypotension.
F. Vital signs every 1 hour: Monitoring vital signs is important for ongoing assessment, but it is not as urgent as administering oxygen and fluids. Vital signs should be monitored closely, but immediate interventions to address hypoxemia and hypovolemia are critical to stabilize the client's condition.
G. Give 1 Liter bolus of 0.9% sodium chloride solution IV once: The client's hypotension (blood pressure of 83/41 mm Hg) indicates hypovolemia and the need for fluid resuscitation. Administering a bolus of intravenous fluids (1 Liter bolus of 0.9% sodium chloride solution) is essential to address hypovolemia and improve perfusion to vital organs. This intervention helps stabilize the client's blood pressure and prevent further deterioration of her condition.
Correct Answer is D
Explanation
A. Histamine 2-receptor antagonists do not directly neutralize hydrochloric acid (HCl) in the stomach. Instead, they reduce acid secretion by blocking the histamine 2 receptors on parietal cells, thereby decreasing the production of gastric acid.
B. This describes the mechanism of action of anticholinergic medications, not histamine 2- receptor antagonists.
C. Histamine 2-receptor antagonists do not have antimicrobial properties and are not used to destroy microorganisms causing stomach inflammation. They primarily target acid secretion.
D. This is the correct purpose of histamine 2-receptor antagonists. They work by blocking the action of histamine on parietal cells in the stomach, leading to a reduction in the secretion of hydrochloric acid. This helps in the management of peptic ulcer disease and other conditions related to excessive gastric acid secretion.
