The nurse is caring for a patient receiving warfarin and notes bruising and petechiae on the patient's extremities.
The nurse will request an order for which?

Choice A rationale

Thiazide diuretics do not block the sodium pump. They act primarily on the distal convoluted tubule in the kidneys.

Choice B rationale

Thiazide diuretics block the chloride pump in the distal convoluted tubule, preventing the reabsorption of sodium and chloride, leading to increased urine output and decreased blood pressure.

Choice C rationale

Thiazide diuretics do not block the carbonic anhydrase pump. This action is associated with carbonic anhydrase inhibitors.

Choice D rationale

Thiazide diuretics do not block the potassium pump. They can cause potassium loss as a side effect, but this is not their primary mechanism of action.

Choice A rationale

Asking the patient what time of day the medication is taken can help identify if taking it at a different time might alleviate sleep disturbances. SSRIs like sertraline can cause insomnia if taken later in the day.

Choice B rationale

Recommending a weekly dosage is inappropriate and could potentially disrupt the therapeutic effect. SSRIs should be taken daily, as prescribed.

Choice C rationale

Counseling the patient to take the medication at bedtime could worsen sleep disturbances, as sertraline may cause insomnia in some individuals. Timing should be adjusted based on patient response.

Choice D rationale

Suggesting a lower dose without consulting the provider may not address the issue effectively and could reduce the efficacy of the medication. Dosage adjustments should be made based on clinical assessment and provider recommendation.
