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 A

Explanation

Rationale for A: Redressing the abdominal incision is crucial as the dressing is no longer occlusive, which could lead to infection. An intact dressing also prevents the client from picking at the site, which could cause further harm or delay healing.
Rationale for B: Leaving the lights on might help with visual perception for a client with dementia, but it does not directly address the immediate risk of infection or the client's interference with the dressing.
Rationale for C: Applying restraints could be considered for a client who is at risk of harming themselves, but this should be a last resort after other interventions have been tried due to the potential for physical and psychological harm.
Rationale for D: Replacing the IV site with a smaller gauge is not indicated by the pink insertion site alone and does not address the client's confusion or behavior towards the dressing.

A. Verify the prothrombin time (PT). B. Administer prescribed sedative. C. Select a monitor lead with a tall R wave. D. Activate the synchronization mode.

Correct Answer is D

Explanation

A. Verify the prothrombin time (PT).
While it is important to verify coagulation status in patients with atrial fibrillation to ensure they are not at high risk for bleeding, this is not the most critical step immediately prior to
cardioversion. The PT is more relevant if anticoagulation therapy is being managed.

B. Administer prescribed sedative.
Administering a sedative is important for patient comfort during the procedure, but it is not the most critical step that directly affects the success and safety of the cardioversion itself.

C. Select a monitor lead with a tall R wave.
Selecting a monitor lead with a tall R wave helps in accurately synchronizing the cardioversion shock with the R wave, but this is secondary to activating the synchronization mode which is critical to avoid delivering a shock during the vulnerable period of the cardiac cycle.

D. Activate the synchronization mode.
This is the correct answer. The most important action before deploying the current for cardioversion is to ensure the defibrillator is in synchronization mode. Synchronization ensures that the electrical shock is delivered at the correct time during the cardiac cycle, specifically on the R wave of the QRS complex, to avoid inducing ventricular fibrillation. This is crucial for
patient safety.
