A nurse is caring for a client who has named a person to serve as his health care proxy. The client talks about this type of advance directives. Which of the following statements by the client indicates a need for clarification?

A. "I will feel less hungry during meals while I am taking orlistat": Orlistat works by blocking the absorption of dietary fat in the intestines rather than suppressing appetite. Therefore, it does not typically reduce hunger during meals.
B. "I will eat a no-fat diet to prevent side effects from the medication": Orlistat can cause gastrointestinal side effects such as oily stools, fecal incontinence, and flatulence, particularly when consumed with high-fat meals. While reducing fat intake can help minimize these side effects, it is not necessary to eliminate fat entirely from the diet. The statement is partially correct but not the best response indicating full understanding.
C. "I will stop taking orlistat and call my doctor if my urine gets darker in color": Dark urine can indicate liver problems, which are a potential side effect of orlistat. Therefore, it is crucial for the client to monitor for this symptom and contact their healthcare provider if it occurs. This response indicates that the client understands the potential adverse effects of the medication.
D. "I will take my dose of orlistat every morning an hour before breakfast": Orlistat is typically taken with meals or up to one hour after eating. Taking it on an empty stomach before breakfast is not recommended.

A. "The oral medication you will take after this IV will dissolve the clot": This statement is incorrect. While anticoagulants like warfarin or direct oral anticoagulants (DOACs) may be prescribed to prevent the formation of new clots or to treat existing clots, heparin, whether administered intravenously or subcutaneously, is not typically used to dissolve existing clots.
B. "A pharmacist is the person to answer that question": This response deflects the client's question and does not provide useful information. While pharmacists are knowledgeable about medications, nurses are responsible for educating clients about their treatments and should be able to provide accurate information regarding heparin therapy.
C. "Heparin does not dissolve clots. It stops new clots from forming": This is the correct response. Heparin is an anticoagulant medication that works by inhibiting the formation of new clots rather than dissolving existing ones. It does so by inhibiting the activity of clotting factors in the blood, thus preventing the clot from enlarging or new clots from forming.
D. "It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level": While this statement provides information about the time required for heparin to achieve a therapeutic effect, it does not address the client's specific question about clot dissolution. Heparin's anticoagulant effects occur rapidly, but its primary action is prevention rather than dissolution of existing clots.
