An adult with arthritis has been receiving treatment with naproxen and now reports ongoing stomach pain, increasing weakness, and fatigue. Which laboratory test should the nurse monitor?

Choice A: Obtain a capillary glucose level. This is the first action that the nurse should do, as it can diagnose hypoglycemia, which is a low blood sugar level that can cause jitteriness and tachypnea in newborns. Hypoglycemia can be caused by maternal diabetes, prematurity, infection, or delayed feeding. The nurse should check the glucose level using a heel stick and a glucometer.

Choice B: Feed 30 mL of 10% dextrose in water. This is not the first action that the nurse should do, as it may not be appropriate for all newborns with jitteriness and tachypnea. Feeding 10% dextrose in water can raise the blood sugar level, but it may also cause rebound hypoglycemia or fluid overload. The nurse should feed only after confirming hypoglycemia and obtaining a healthcare provider's order.

Choice C: Wrap tightly in a blanket. This is not the first action that the nurse should do, as it may not address the underlying cause of jitteriness and tachypnea in newborns. Wrapping tightly in a blanket can prevent heat loss and conserve energy, but it may also impair breathing or circulation. The nurse should wrap only after ruling out other causes of jitteriness and tachypnea.

Choice D: Encourage the mother to breastfeed. This is not the first action that the nurse should do, as it may not be feasible or effective for all newborns with jitteriness and tachypnea. Breastfeeding can provide nutrition and bonding for newborns, but it may also be difficult or contraindicated for some newborns with respiratory distress or infection. The nurse should encourage breastfeeding only after assessing and stabilizing the newborn's condition.

Choice A: Securing chest tube to the stretcher for transport is a good practice, but it is not the most important action. The chest tube should be secured to prevent accidental dislodgement or kinking, but it does not affect the function of the chest tube or the drainage system.

Choice B: Administering PRN pain medication prior to transport is a compassionate action, but it is not the most important action. The client may experience pain due to the chest tube, the intubation, or the underlying condition, but pain relief is not a priority over maintaining adequate ventilation and drainage.

Choice C: Marking the amount of chest drainage on the container is a useful action, but it is not the most important action. The amount of chest drainage should be recorded and reported to monitor the client's status and detect any complications, such as hemorrhage or infection, but it does not affect the immediate function of the chest tube or the drainage system.

Choice D: Keeping the chest tube container below the site of insertion is the most important action for the nurse to take. The chest tube container should be kept below the level of the client's chest to maintain a gravity-dependent pressure gradient that allows air and fluid to drain from the pleural space. If the container is raised above the site of insertion, it can cause backflow of air or fluid into the pleural space, which can compromise ventilation and cause tension pneumothorax.
