Which assessment finding for a patient who is receiving IV furosemide(Lasix) to treat stage 2 hypertension is most important to report to the health care provider?

Correct Answer: B

Rationale: Hypokalemia is a frequent adverse effect of the loop diuretics and can cause life-threatening dysrhythmias. The health care provider should be notified of the potassium level immediately and administration of potassium supplements initiated. The elevated blood glucose and BP also indicate a need for collaborative interventions but will not require action as urgently as the hypokalemia. An orthostatic drop of 12 mm Hg is common and will require intervention only if the patient is symptomatic.

Correct Answer: D

Rationale: Capillaries contain a significant proportion of blood volume due to their extensive network and large surface area.

Correct Answer: D

Rationale: Magnesium helps counteract digitalis toxicity by stabilizing cardiac membranes and reducing arrhythmogenic effects.

Correct Answer: D

Rationale: Vascular resistance is primarily influenced by the diameter of the blood vessel, although other factors like length and viscosity also play roles.
