A nurse is caring for a client who has a peripherally inserted central catheter (PICC) for the administration of total parenteral nutrition (TPN). The transparent dressing over the insertion site requires replacement. Which of the following actions should the nurse take?

Choice A reason: A client with type 1 diabetes mellitus who has taken a high dose of insulin is at significant risk for hypoglycemia. In type 1 diabetes, the body does not produce insulin, so insulin therapy is essential for controlling blood glucose levels. However, if the dose of insulin is too high relative to the patient's dietary intake or physical activity level, it can lead to a rapid decrease in blood glucose levels, resulting in hypoglycemia. Hypoglycemia is defined as a blood glucose level less than 70 mg/dL (3.9 mmol/L) and can cause symptoms such as confusion, sweating, weakness, and in severe cases, seizures or loss of consciousness.

Choice B reason: A client with type 2 diabetes who has not taken any medication may have elevated blood glucose levels but is not typically at immediate risk for hypoglycemia unless they are taking medications that lower blood glucose. Type 2 diabetes is characterized by insulin resistance, and while medication can help manage it, skipping medication does not usually result in hypoglycemia unless other factors are at play.

Choice C reason: An older adult client taking an antibiotic for an infection is not generally at risk for hypoglycemia unless the antibiotic interacts with other medications that the client is taking for diabetes management. Antibiotics themselves do not typically cause hypoglycemia.

Choice D reason: A client who has metabolic syndrome and is taking a statin drug to lower cholesterol levels is not at direct risk for hypoglycemia from the statin medication. Metabolic syndrome is a cluster of conditions that increase the risk for heart disease, stroke, and type 2 diabetes. While statins are used to lower cholesterol levels, they do not have a direct impact on blood glucose levels that would lead to hypoglycemia.

Choice A reason: Papilledema, which is the swelling of the optic disc due to increased ICP, is not typically an early sign. It is usually a later manifestation because it takes time for the pressure to build up and affect the optic nerve.

Choice B reason: Restlessness can be an early sign of increased ICP. As ICP begins to rise, it can cause subtle changes in a person's level of consciousness, leading to agitation or restlessness. This is often one of the first signs that healthcare providers notice when monitoring for changes in neurological status.

Choice C reason: Projectile vomiting may occur with increased ICP, but it is not usually an early sign. It tends to occur after other symptoms such as headache and altered consciousness and is more indicative of significant pressure increases that affect the brainstem.

Choice D reason: Decorticate posturing is a severe sign of brain injury associated with increased ICP but is not an early sign. It indicates significant damage to the brain and is a late and ominous sign in the progression of increased ICP.
