A nurse is planning care for a client who is postoperative following the insertion of an arteriovenous graft in their left forearm. Which of the following actions should the nurse include in the plan of care?

Choice A reason: A heart rate of 60/min is within the normal range for an adult, and while it may be considered on the lower end, it is not in itself an indication to increase dopamine dosage. Dopamine is used to increase heart rate and cardiac output, but a rate of 60/min does not typically warrant an increase in dosage unless accompanied by other signs of inadequate perfusion.

Choice B reason: An oxygen saturation of 95% is within the normal range for arterial blood gases and is not an indication to increase dopamine dosage. Oxygen saturation reflects the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen.

Choice C reason: A blood pressure of 90/50 mm Hg is considered low and can be an indication for increasing the dopamine dosage in a client with hypovolemic shock. Dopamine increases blood pressure by vasoconstriction and increasing cardiac output, which is critical in managing shock.

Choice D reason: A respiratory rate of 14/min is within the normal range for adults and is not an indication to increase dopamine dosage. The respiratory rate should be monitored for changes that could indicate worsening of the client's condition, but on its own, it does not dictate adjustments to dopamine therapy.

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.
