Your labs are potassium 6.4, sodium 138, and serum calcium level of 9. Which order from the healthcare provider would the nurse anticipate?

Fluid restriction

Neomycin

Kayexalate

Sodium chloride infusion and furosemide

Answer and Explanation

The Correct Answer is C

Choice A reason: Fluid restriction doesn’t address hyperkalemia (6.4 mEq/L); it may concentrate potassium further, worsening the condition, as it’s unrelated to potassium excretion or shifting in this scenario.

Choice B reason: Neomycin, an antibiotic, reduces gut bacteria but isn’t used for hyperkalemia. It has no direct effect on potassium levels, making it irrelevant for this lab finding.

Choice C reason: Kayexalate binds potassium in the gut, facilitating its fecal excretion, effectively lowering serum levels (6.4 mEq/L) in hyperkalemia, aligning with urgent correction needs here.

Choice D reason: Sodium chloride and furosemide dilute and excrete potassium via urine, but Kayexalate is preferred for rapid gut-based removal when potassium is critically high (6.4 mEq/L).

Correct Answer is B

Explanation

Choice A reason: Elevating legs above heart level aids venous return, not arterial flow, worsening PAD’s poor circulation, reducing oxygen to ischemic tissues further.

Choice B reason: Warm environments dilate peripheral vessels, improving blood flow to PAD-affected limbs, reducing claudication pain and supporting tissue perfusion safely.

Choice C reason: Heating pads risk burns in PAD due to reduced sensation and poor healing, potentially worsening ischemic damage rather than relieving pain effectively.

Choice D reason: Antiembolic stockings prevent clots in venous stasis, not PAD, an arterial issue, and may compress arteries, further impairing circulation to legs.

A. Albumin and furosemide B. A high fiber diet with increased fluid intake C. Maintain NPO and IV fluids D. Obtain a consent for a barium enema

Correct Answer is C

Explanation

Choice A reason: Albumin and furosemide treat fluid shifts or edema, not acute diverticulitis, which requires bowel rest, not volume or protein correction initially.

Choice B reason: High fiber aids chronic diverticulosis, but in acute diverticulitis, it worsens inflammation; rest, not fiber, is needed during active infection.

Choice C reason: NPO and IV fluids rest the bowel, reducing inflammation and perforation risk in acute diverticulitis, while maintaining hydration, the standard approach.

Choice D reason: Barium enema risks perforation in acute diverticulitis due to inflamed diverticula; it’s contraindicated until inflammation subsides, not ordered acutely.
