A nurse is caring for a newly admitted patient who will receive Digoxin to treat cardiac dysrhythmia.
The patient takes hydrochlorothiazide and reports regular use of OTC laxatives.
Before administering the first dose of Digoxin, the nurse will review the patient’s electrolyte levels with careful attention to which electrolytes?

Choice A rationale

Sumatriptan does not cause vasodilation of peripheral blood vessels. Instead, it has vasoconstrictive properties.

Choice B rationale

Sumatriptan does not depress pain response in the central nervous system. Its primary action is on the cranial blood vessels.

Choice C rationale

Sumatriptan is a selective serotonin receptor agonist that causes vasoconstriction of cranial blood vessels, relieving migraine headaches.

Choice D rationale

Sumatriptan does not bind to acetylcholine receptors or prevent nerve transmission. It specifically targets serotonin receptors in cranial blood vessels.

Choice A rationale

Peripheral edema is more commonly associated with right-sided heart failure rather than left-sided. This is because right-sided heart failure leads to systemic venous congestion, causing fluid to accumulate in the peripheral tissues, particularly in the legs and ankles.

Choice B rationale

Pulmonary edema is a major concern in left-sided heart failure due to the inability of the left ventricle to effectively pump blood out to the systemic circulation. This results in blood backing up into the pulmonary veins, leading to fluid accumulation in the lungs.

Choice C rationale

Liver edema, or hepatomegaly, is more typically seen in right-sided heart failure, where the failure of the right ventricle causes blood to back up into the systemic circulation, affecting the liver and other organs.

Choice D rationale

Abdominal edema, or ascites, is also more associated with right-sided heart failure. This condition occurs due to increased pressure in the veins and capillaries, leading to fluid leakage into the abdominal cavity.
