A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin.
Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?

Choice A rationale:

Expecting to have a rapid pulse rate for the first few weeks is not accurate information for a client with a newly implanted implantable cardioverter-defibrillator (ICD). After the ICD placement, the client's heart rate should stabilize within normal ranges. A consistently rapid pulse rate might indicate an issue with the device or the client's cardiovascular system, necessitating further evaluation.

Choice B rationale:

Returning in two weeks for a follow-up MRI is not advisable immediately after ICD placement. MRI (Magnetic Resonance Imaging) is contraindicated for individuals with ICDs due to the magnetic fields, which can interfere with the functioning of the device. The timing and necessity of any future MRI should be carefully planned and discussed with the healthcare provider in charge of the client's care.

Choice C rationale:

Resuming tub baths and swimming after 24 hours is not recommended after ICD placement. Submerging the ICD site in water, especially in the initial healing phase, can increase the risk of infection. Clients with newly implanted ICDs are usually advised to avoid submerging the device site in water for a specified period, as recommended by their healthcare provider.

Choice D rationale:

Wearing loose-fitting clothing is important advice for clients with newly implanted ICDs. Tight clothing, especially around the site of the device, can cause irritation and discomfort. Loose-fitting clothing ensures proper airflow to the site, reducing the risk of irritation and allowing for optimal healing. It is essential to provide this information to the client to promote comfort and prevent complications related to the ICD placement.

Choice A rationale:

Administering 2 ounces of water to the newborn prior to the test is not a standard practice for newborn genetic screening. Newborns are typically screened for genetic disorders through a blood test, not by giving them water.

Choice B rationale:

This statement is incorrect. Newborn genetic screening is usually performed shortly after birth, not at 2 months old. Early screening allows for the early detection of certain genetic disorders, enabling timely interventions if needed.

Choice D rationale:

Drawing blood from the newborn's inner elbow is not specific guidance related to newborn genetic screening. Blood can be drawn from various sites, and healthcare providers choose the most appropriate site based on the newborn's condition and the required tests.
