Which insulin is used for basal dosing for 24-hour coverage and has no peak?

Choice A rationale

Checking blood pressure does not directly address the faint pulses and cool foot. While hypotension could contribute to peripheral perfusion issues, the signs described more likely indicate compartment syndrome, which requires urgent action.

Choice B rationale

Repositioning the leg might provide some comfort but does not alleviate the potential compartment syndrome. Elevation could worsen ischemia by reducing arterial blood flow.

Choice C rationale

Compartment syndrome is a medical emergency caused by increased pressure within a muscle compartment. This pressure compromises circulation and tissue viability. The nurse must notify the health care provider immediately to prevent permanent damage.

Choice D rationale

Assessing the incision for redness delays addressing the critical signs of potential compartment syndrome. Redness indicates infection, but faint pulses and a cool extremity necessitate more urgent evaluation.

Choice A rationale

Applying a warm pack is inappropriate for controlling active bleeding, as it can exacerbate blood flow to the site, worsening the hemorrhage rather than controlling it effectively.

Choice B rationale

Using a tourniquet above the bleeding site is a last-resort method typically reserved for life-threatening bleeding. It may cause complications such as nerve damage or ischemia, so other measures are prioritized first.

Choice C rationale

Direct pressure or sterile pressure dressing with elevation minimizes blood loss effectively by compressing the damaged vessels, promoting clot formation, and utilizing gravity to reduce the pressure at the wound site. It is the recommended first-line method.

Choice D rationale

Placing an ice pack on the bleeding site may reduce localized blood flow by inducing vasoconstriction but is less effective than direct pressure for stopping active hemorrhage. It is secondary to other control measures.
