A nurse is planning to obtain blood from a newborn via a heel stick. Which of the following actions should the nurse take?

Answer: B. Compare the result with the baseline reading

Rationale:

A. Check the client's heart rate on the oximeter:
Although checking the heart rate may provide context for assessing the client's overall status, it does not address the primary concern of the low oxygen saturation. Understanding the client's baseline saturation level takes priority to guide further actions effectively.

B. Compare the result with the baseline reading:
Comparing the reading with the client's baseline is essential. For clients with chronic respiratory conditions, baseline oxygen levels may naturally be lower. Identifying if this 88% saturation is typical or unusual for the client helps determine the need for further intervention or adjustment.

C. Decrease the amount of oxygen administered:
Reducing oxygen flow when the saturation is low is contraindicated, as it could worsen hypoxia. Instead, increasing oxygen may be warranted if the reading remains below the baseline after further assessment.

D. Perform another reading while the client ambulates:
Repeating the reading during ambulation may worsen hypoxia and is not ideal without understanding baseline oxygenation at rest. Re-evaluation at rest or in a different position may be more appropriate for accurate assessment.

Answer: D

Rationale:

A) Collect 2 mL of sputum in an emesis basin: Collecting sputum in an emesis basin is inappropriate for laboratory testing. The sputum should be collected directly into a sterile container to prevent contamination. This ensures that the culture and sensitivity results are accurate and reflect the client's true respiratory pathogens.

B) Instruct the client to rinse with an antiseptic mouthwash prior to specimen collection: Using an antiseptic mouthwash before collecting a sputum sample is not recommended because it may alter the flora present in the sputum, leading to inaccurate culture results. Instead, the client should rinse their mouth with plain water to clear excess saliva or food debris.

C) Swab the oropharynx with a sterile swab: Swabbing the oropharynx does not obtain sputum from the lungs but instead gathers a sample from the throat, which may not be reflective of lower respiratory infections. A proper sputum sample is produced through a deep cough to collect material directly from the lungs.

D) Refrigerate the specimen until the time of transport to the laboratory: Refrigerating the sputum specimen helps to preserve its integrity by preventing the overgrowth of bacteria or other pathogens until it can be transported to the laboratory. Proper refrigeration ensures that the culture and sensitivity results remain accurate.
