A nurse is collecting data from a newborn who was born 24 hrs ago. Which of the following images should the nurse identify as an indication that the newborn has erythema toxicum?

A. Anorexia: Anorexia, or loss of appetite, is not a typical adverse effect directly associated with heparin use. While it may occur due to general postoperative factors, it is not an urgent or life-threatening reaction that necessitates immediate reporting related to anticoagulant therapy.

B. Epistaxis: Epistaxis, or nosebleed, is a sign of potential bleeding complications, which is a major adverse effect of heparin. Because heparin inhibits clot formation, any evidence of spontaneous bleeding must be reported immediately to the provider to assess for potential heparin-induced bleeding disorders.

C. Weight gain: Weight gain could suggest fluid retention, but it is not a typical adverse effect of heparin. While postoperative clients should be monitored for signs of fluid imbalance, sudden bleeding signs like epistaxis are far more critical to recognize and report when administering anticoagulants.

D. Bradycardia: Bradycardia, or slow heart rate, is not commonly linked to heparin therapy. While abnormal heart rhythms may occur postoperatively for other reasons, they are not typically associated with bleeding risks from heparin and thus do not require urgent reporting specific to heparin use.

A. Maintain 30 ml sterile water in the drainage collection chamber: The sterile water is maintained in the water-seal chamber, not the drainage collection chamber. The water-seal chamber typically holds about 2 cm of water to create a one-way valve preventing air from entering the pleural space, not 30 mL in the drainage area.

B. Place the drainage device level with the tube insertion site: The drainage device should always be kept below the level of the chest tube insertion site to allow gravity to assist drainage and to prevent backflow of fluid or air into the pleural cavity, which could cause complications.

C. Keep system tubing connections taped together: Taping the system tubing connections securely helps maintain a closed system, preventing accidental disconnections that could lead to air leaks or loss of the negative pressure needed for proper lung re-expansion. This is essential for the effectiveness of chest tube management.

D. Empty the drainage collection chamber every 4 hr: The drainage collection chamber is not emptied routinely. Instead, it is replaced when full or according to facility protocol. Frequent opening of the system increases the risk of introducing infection or losing the closed negative-pressure system.
