A nurse is reviewing home care with a client who has multiple sclerosis. Which of the following precautions should the nurse recommend to promote client safety?

Choice A reason: Amitriptyline, a tricyclic antidepressant, typically causes hypotension via alpha-adrenergic blockade, not hypertension. Expecting blood pressure elevation shows misunderstanding, as its cardiovascular effects require monitoring for orthostatic changes, not hypertensive risks, in depression treatment.
Choice B reason: Acknowledging a 2-4 week delay for amitriptyline’s effect shows understanding, as tricyclics increase synaptic serotonin and norepinephrine gradually, requiring neuroplastic changes for mood improvement. This reflects accurate knowledge of the drug’s onset, critical for managing expectations in depression therapy.
Choice C reason: Taking amitriptyline on an empty stomach is incorrect, as food reduces gastrointestinal side effects like nausea. Its absorption is unaffected by food, but taking it with meals improves tolerability, indicating a misunderstanding of administration guidelines for effective therapy.
Choice D reason: Morning dosing of amitriptyline is incorrect, as its sedative effects, via histamine blockade, are best utilized at bedtime to aid sleep. Morning use may cause daytime drowsiness, reducing adherence, indicating a misunderstanding of its pharmacological profile in depression management.

Choice A reason: Using gauze to cover an infant’s IV site obscures visualization, delaying detection of infiltration or infection. Transparent dressings are preferred, as infants’ small veins are prone to complications. Gauze increases risk by hiding signs like swelling, critical for early intervention in pediatric IV management.
Choice B reason: Monitoring an IV site every 8 hours is inadequate for infants, who need hourly checks due to small vein fragility and high infiltration risk. Frequent assessment detects complications like phlebitis or extravasation early, ensuring vascular integrity and preventing tissue damage in pediatric patients.
Choice C reason: Inserting an IV in the foot is less preferred, as scalp or hand veins are more accessible and stable in infants. Foot IVs risk dislodgement from movement and may impair circulation, increasing complications like tissue damage, making this a suboptimal choice for IV placement.
Choice D reason: A 24-gauge catheter is ideal for infants, as their small veins require smaller needles to minimize trauma and infiltration. This size ensures adequate fluid or medication delivery while reducing vascular damage, aligning with pediatric IV guidelines for safe and effective venous access.
