Shake the bag to mix the fat.

Administer the bag of solution.

Return the bag to the pharmacy.

Turn the bag upside down one time.

Answer and Explanation

The Correct Answer is C

Choice A reason:Shaking the bag is not recommended as it may not adequately mix the solution and could cause emulsion instability.

Choice B reason:Administering the bag as is could be harmful due to the risk of fat embolism or other complications from an unstable emulsion.

Choice C reason:Returning the bag to the pharmacy is the appropriate action to ensure the client receives a properly mixed and safe emulsion.

Choice D reason:Turning the bag upside down one time is not sufficient to mix the emulsion and does not address the potential instability of the solution.

Correct Answer is D

Explanation

Choice A reason: Instructing the client to perform range-of-motion exercises to his lower extremities immediately after cardiac catheterization is not recommended. The client should maintain bed rest with the affected leg straight to prevent bleeding from the catheter insertion site.

Choice B reason: Ambulating the client 1 hour following the procedure is not advised. After femoral artery access, the client is typically required to remain on bed rest with the affected leg straight for several hours to ensure hemostasis and prevent bleeding².

Choice C reason: Restricting the client's fluid intake is not a standard post-procedure action. Adequate hydration is important after cardiac catheterization to help flush the contrast dye used during the procedure from the body, unless contraindicated.

Choice D reason: Assessing the color, temperature, and pulse in the affected extremity is crucial for detecting signs of bleeding, hematoma formation, or arterial occlusion. These assessments should be performed regularly as part of post-cardiac catheterization care².

A. "These tests will enable the provider to determine the heart structure and mobility of the heart valves." B. "Cardiac enzymes will identify the location of the MI." C. "Cardiac enzymes assist in diagnosing the presence of pulmonary congestion." D. "These tests help determine the degree of damage to the heart tissues."

Correct Answer is D

Explanation

Choice A reason:Cardiac enzyme studies do not provide information about the heart's structure or the mobility of the heart valves; imaging studies are used for that purpose.

Choice B reason:While cardiac enzymes indicate damage to heart tissues, they do not pinpoint the exact location of an MI; imaging studies are needed for localization.

Choice C reason:Cardiac enzymes are not used to diagnose pulmonary congestion; they are specific markers for myocardial injury.

Choice D reason:Cardiac enzyme levels, such as troponin, rise when there is damage to the heart muscle, which is why they are used to assess the degree of damage after an MI.
