The essential idea here is that DKA and HHS are distinct metabolic emergencies, and nursing care hinges on recognizing those differences and applying protocol-based fluid and electrolyte management while watching for neurologic complications. DKA features metabolic acidosis with ketosis (typically with elevated anion gap and ketones) and often occurs in younger patients with type 1 diabetes; HHS features very high glucose with high serum osmolality and minimal or no ketosis, usually in older patients with type 2 diabetes. So the best approach emphasizes treating each condition according to its presentation: aggressive IV fluids and careful electrolyte management per protocol, continuous glucose monitoring, and vigilance for cerebral edema risk. In DKA, expect shifts in potassium with insulin and fluids and consider bicarbonate if pH is very low; in HHS, focus on correcting dehydration and osmolar balance with gradual glucose reduction. Along with fluids and electrolytes, monitor mental status and signs of neurological changes, and reassess frequently for triggers such as infection. The other options miss these distinctions or oversimplify management, which is why this integrated approach is the most accurate.

Uremia results from the buildup of waste products in the blood when the kidneys fail, and those toxins affect multiple body systems. The gastrointestinal tract is particularly sensitive to this toxin load, leading to nausea as a direct and common symptom of advanced CKD. When nausea is present, patients often eat less, which explains accompanying weight loss and also contributes to malnutrition seen in later-stage kidney disease. Itching can occur in CKD due to mineral disturbances, but it’s not as universally tied to the toxin accumulation driving uremia itself, and decreased appetite or weight loss are more often downstream effects of the nausea and overall illness. So nausea best fits as the symptom most commonly associated with uremia in advanced CKD.

Restraints should be used only after less restrictive measures have failed and there is a physician’s order, with ongoing evaluation and regular reassessment to determine continued need. The focus is on safety and protecting the patient’s rights. This approach ensures you first try de‑escalation and environment-based strategies, obtain proper authorization, and continuously monitor for efficacy and potential harm. Staff must routinely check the patient's condition, ensure circulation and skin integrity, monitor vital signs, and reassess the need for restraint, removing it as soon as the patient can be safely managed without it. Using restraints simply because someone is agitated, or applying them without monitoring, or removing them only by physician order, does not align with proper practice.

Steal syndrome happens when blood is redirected from the hand into the arteriovenous access, reducing distal arterial flow. The key warning sign that this has progressed to needing surgical intervention is distal ischemia—cold or numb fingers in the hand, or other ischemic symptoms—that show the hand isn’t getting enough blood despite a functioning access. This contrast with other findings: a thrill at the graft site means the access is patent and carrying flow; normal distal pulses with a palpable bruit suggest good perfusion to the hand; redness at the access site without ischemic symptoms could indicate irritation or infection rather than compromised distal blood flow. When ischemia presents, it indicates the need to surgically revise the access to restore adequate distal perfusion.
