A nurse is teaching a client who is to undergo placement of a nontunneled percutaneous central venous access device. Which of the following statements should the nurse include in the teaching?

Choice A reason: Adding salt to season foods can irritate oral sores in AIDS patients, often caused by candidiasis or herpes. Salt exacerbates pain and delays healing, making this instruction harmful and inappropriate for managing oral discomfort in this population.
Choice B reason: Rinsing with alcohol-based mouthwash worsens oral soreness, as alcohol irritates mucosal lesions common in AIDS. Non-alcohol, antiseptic, or saline rinses are preferred to promote comfort and healing, making this instruction incorrect and potentially painful.
Choice C reason: Eating hot foods can aggravate oral sores, increasing pain and delaying healing in AIDS patients with mucosal damage. Lukewarm or cool foods are better tolerated, making this instruction inappropriate and counterproductive for managing the client’s symptoms.
Choice D reason: Using ice chips numbs the mouth, reducing pain from oral sores during eating for AIDS patients. This non-invasive, soothing intervention is safe and effective, aligning with comfort-focused care for mucosal lesions, making it the correct instruction.

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.
