Correct Answer is D
Explanation
This is the finding that the PN should instruct the postpartum client to report to the charge nurse because it may indicate an infection, such as endometritis, mastitis, or urinary tract infection, that requires prompt treatment. The PN should also instruct the client to monitor for other signs of infection, such as foul-smelling lochia, redness or tenderness of the breasts, or dysuria.
A. Increased diaphoresis during the day and night is a normal finding in the postpartum period and does not need to be reported. It is caused by hormonal changes and fluid shifts that occur after delivery.
B. Breast engorgement on the fourth postpartum day is a normal finding in the postpartum period and does not need to be reported. It is caused by increased blood flow and milk production in the breasts.
C. Lochia color that changes to light pink or white is a normal finding in the postpartum period and does not need to be reported. It indicates that the uterine lining is healing and regenerating after delivery.
Correct Answer is B
Explanation
PVCs are abnormal heartbeats that occur when a ventricle contracts earlier than expected. They can indicate electrolyte imbalance, such as hypokalemia, which can result from NG suctioning. The PN should report this finding to the healthcare provider, as it may require treatment or adjustment of the suctioning.
The other options are not correct because:
A. Hyperactive bowel sounds on assessment may indicate increased peristalsis or bowel obstruction, but they are not related to the client's symptoms or NG suctioning.
C. Hypoactive bowel sounds on assessment may indicate decreased peristalsis or ileus, which are expected after bowel surgery and do not require immediate intervention.
D. Regular heart rate of 100 beats per minute on telemetry may indicate tachycardia, which can have various causes, but it is not as concerning as PVCs in this context.
