(Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

To determine how many tablets of digoxin 0.125 mg are needed to administer a total dose of 0.25 mg, divide the desired dose by the dose per tablet:

0.25 mg (desired dose) ÷ 0.125 mg (dose per tablet) = 2 tablets

Therefore, the nurse should administer 2 tablets of digoxin 0.125 mg to the client to achieve a total dose of 0.25 mg.

Correct Answer is D

Explanation

A. Diminished effect from warfarin: This is unlikely because displacement of warfarin from protein binding sites would increase its concentration in the bloodstream, potentially leading to increased anticoagulant effects and toxicity.

B. Diminished effect from paroxetine: This is also unlikely because displacement of paroxetine from protein binding sites would increase its concentration in the bloodstream, potentially leading to increased pharmacological effects and toxicity.

C. Increased effect, and toxicity from paroxetine: If paroxetine displaces warfarin from protein binding sites, it can increase the concentration of free warfarin in the bloodstream, leading to increased anticoagulant effects and potential toxicity.

D. Increased effect, and toxicity from warfarin: Correct. If warfarin is displaced from protein binding sites by paroxetine, it can increase the concentration of free warfarin in the bloodstream, leading to increased anticoagulant effects and potential toxicity.

A. Most CAM therapies are totally ineffective B. Additional treatment may not be needed C. Patients must be warned that most CAM therapies are dangerous D. CAM therapies could interact with prescription and OTC medications

Correct Answer is D

Explanation

A. Most CAM therapies are totally ineffective: Incorrect. Dismissing all CAM therapies as ineffective without considering individual cases could lead to overlooking potentially helpful treatments for patients.

B. Additional treatment may not be needed: Incorrect. Collecting information about CAM use allows healthcare providers to assess the overall treatment regimen comprehensively.

C. Patients must be warned that most CAM therapies are dangerous: Incorrect. While some CAM therapies may carry risks, it's not accurate to generalize that most CAM therapies are dangerous.

D. CAM therapies could interact with prescription and OTC medications: Correct. Understanding potential interactions between CAM therapies and conventional medications is essential for patient safety and optimal treatment outcomes.
