A nurse is assessing a 5-year-old child who has diabetes insipidus and is receiving desmopressin.
Which of the following findings should the nurse identify as an indication that the medication is effective?

The correct answer is D.

Choice A reason: “A. Using this machine increases my risk of overdose.” This statement is incorrect because PCA pumps are designed with safety mechanisms to prevent overdose. The pump is programmed to deliver a specific dose of medication at set intervals, and it will not dispense more medication than what is prescribed by the healthcare provider.

Choice B reason: “B. I can get pain medication any time as long as I press the button.” While it is true that the patient can self-administer medication, PCA pumps have a lockout interval that prevents the machine from delivering another dose until a certain amount of time has passed, ensuring that the patient cannot receive medication too frequently.

Choice C reason: “C. My partner can press my pain medication button for me if I am sleeping.” This statement is incorrect. Only the patient should press the button on the PCA pump to ensure that the medication is administered safely and according to the patient’s current level of pain. Allowing someone else to press the button could lead to unsafe dosing.

Choice D reason: “D. I will receive a limited amount of pain medication when I press the button.” This is the correct statement. The PCA pump allows the patient to administer a controlled amount of pain medication within safe limits set by the healthcare provider. The pump is programmed to deliver a specific dose of medication, and there is a limit to the number of doses that can be administered per hour.

A.Taping the tube to the child's cheek is not a recommended practice. It can cause skin irritation, discomfort, or even accidental removal of the tube. Proper securing of the tube to the abdomen using appropriate devices is the preferred method to prevent dislodgement.

B.Applying lubricant to the site is not necessary or recommended. The gastrostomy tube should be kept clean and dry. If any secretions or debris are present, they should be gently cleaned with mild soap and water, followed by thorough rinsing and drying.

C.Some gastrostomy tubes require an extension set for feeding, especially low-profile devices (e.g., button-type gastrostomy tubes). This extension makes it easier to administer feeds or medications and can be removed afterward. However, this is not typically part of routine site care.

D.Securing the tubing to the child's abdomen helps prevent accidental dislodgement or pulling of the gastrostomy tube. This can be done using appropriate securing devices, such as adhesive dressings or commercially available tube holders, as recommended by the healthcare provider.
