A nurse is caring for a client who has lung cancer and has a sealed radiation implant. Which of the following actions should the nurse take? (Select all that apply)

Choice A reason: Keeping the drainage bag above waist level promotes urine backflow, increasing infection risk. Bags must be below bladder level to ensure proper urine flow, so this action is incorrect and unsafe, requiring nurse intervention.
Choice B reason: Disconnecting the catheter to empty the bag breaks the closed system, increasing infection risk. The bag should be emptied via the drainage port, so this action is incorrect and requires correction by the nurse.
Choice C reason: Emptying the drainage bag when three-quarters full prevents overfilling, reducing backflow and infection risk. This aligns with proper catheter care protocols, ensuring safety for a fall-risk client, making it the correct technique.
Choice D reason: Using sterile gloves for emptying the drainage bag is unnecessary, as clean gloves suffice for this non-sterile procedure. Sterile gloves are for catheter insertion, so this action is incorrect and inefficient, requiring guidance.

Choice A reason: Hyperactive deep tendon reflexes are not linked to morphine toxicity. Morphine, an opioid, depresses the central nervous system, reducing reflexes. Hyperactive reflexes suggest neurological or stimulant effects, not opioid overdose, which primarily causes respiratory and consciousness depression in affected clients.
Choice B reason: Fluid retention is not a primary sign of morphine toxicity. Morphine may cause urinary retention via sphincter tone increase, but fluid overload is unrelated. Toxicity manifests as respiratory depression or sedation, driven by mu-opioid receptor overstimulation, not fluid balance alterations.
Choice C reason: Prolonged QT interval is associated with medications like antiarrhythmics, not morphine. Morphine toxicity primarily causes respiratory depression and sedation via central nervous system effects. Cardiac effects are rare, and QT prolongation is not a hallmark of opioid overdose in clinical settings.
Choice D reason: Bradypnea indicates morphine toxicity, as opioids depress the brainstem’s respiratory center via mu-receptor overstimulation. This slows breathing, risking hypoxia and respiratory arrest, a life-threatening complication requiring immediate intervention like naloxone to reverse opioid effects and restore normal respiratory function.
