A nurse is reinforcing discharge teaching to a client following arthroscopic (joint) surgery.
To prevent postoperative complications which of the following actions should be reinforced during the teaching of Continuous passive motion (CPM)?

Choice A rationale:

Hypercalcemia. Hypercalcemia refers to an elevated level of calcium in the blood. It is not typically a concern in a newborn, and monitoring for hypercalcemia is not necessary in this context. The infant's weight and maternal diabetes are more relevant factors to consider.

Choice B rationale:

Hypobilirubinemia. Hypobilirubinemia implies a low level of bilirubin in the blood, which is not a common concern in newborns, especially in the context of a newborn's weight and maternal diabetes. Monitoring for hyperbilirubinemia, which can lead to jaundice, would be more appropriate.

Choice C rationale:

Hypoglycemia. Hypoglycemia, or low blood sugar, is a significant concern in newborns of diabetic mothers. Newborns born to diabetic mothers are at increased risk of hypoglycemia due to the abrupt cessation of the continuous glucose supply from the mother's bloodstream after birth. Monitoring the newborn's blood glucose levels is crucial in this case.

Choice D rationale:

Decreased RBC. Monitoring for decreased red blood cell (RBC) counts is not typically a primary concern in a newborn, especially one born to a diabetic mother. Hypoglycemia, which can be a result of maternal diabetes, poses a more immediate and significant threat to the newborn's well-being.

Choice A rationale:

Informed consent is required for invasive procedures that carry significant risks or potential complications. Placement of a central venous catheter is an invasive procedure that involves inserting a catheter into a large vein, often in the neck, chest, or groin. It carries potential risks such as infection, bleeding, and injury to nearby structures. Therefore, informed consent is necessary before performing this procedure.

Choice B rationale:

Insertion of a nasogastric tube is an invasive procedure, but it is generally considered a routine and less risky procedure compared to others. Informed consent is typically not required for nasogastric tube insertion unless there are specific institutional policies or the client lacks decision-making capacity.

Choice C rationale:

Irrigation of a wound with antibiotic solution is a standard nursing procedure, and informed consent is not typically required for wound care unless there are specific circumstances that make it necessary, such as unusual risks or patient-specific considerations.

Choice D rationale:

Administration of an iron injection using Z-track technique is also an invasive procedure, but it is a common and well-established technique for administering intramuscular injections. Informed consent is not routinely required for this procedure unless there are specific institutional policies or the client's condition warrants it.
