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?

The correct answer is choice B: Axillary.

Choice B rationale: The axillary site, or under the arm, is the preferred site for obtaining the temperature of a newborn. This method is safe and generally well-tolerated by infants. It carries a lower risk of injury or discomfort compared to other methods.

Choice A rationale: Rectal temperature measurement can be accurate but is more invasive and may cause discomfort or injury to the newborn. It is generally not the preferred method for routine temperature checks in newborns.

Choice C rationale: Tympanic temperature measurement, which uses the ear canal, may not be accurate for newborns due to their small ear canal size and the presence of vernix caseosa or amniotic fluid.

Choice D rationale: Oral temperature measurement is not suitable for newborns as they cannot hold the thermometer in their mouth safely or reliably. This method is more appropriate for older children and adults.

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.
