A nurse is teaching a class about oxygen transport in the cardiopulmonary system. Which of the following transports oxygen in the blood?

A. Explaining the risks and benefits of the procedure is generally the responsibility of the surgeon or the healthcare provider who will perform the procedure. They are in the best position to provide detailed and specific information about the procedure, including potential complications and benefits.
B. Similar to explaining the risks and benefits, discussing alternatives is usually done by the surgeon or the provider. The nurse should ensure that the client is aware that alternatives are available and that this information has been provided by the appropriate medical professional.
C. It is the responsibility of the surgeon or the healthcare provider to obtain informed consent. However, the nurse should confirm that the consent process has been completed. This means ensuring that the consent form is signed and that the client has been properly informed. While the nurse does not obtain consent, they verify that it has been done correctly.
D. Describing the consequences of not undergoing the surgery is part of the informed consent process and is generally the responsibility of the surgeon. The nurse should ensure that this information has been communicated to the client by the appropriate provider.
E. The nurse often acts as a witness to the client’s signature on the consent form. This involves confirming that the client has signed the form voluntarily and after being fully informed. The nurse’s role in this process is to ensure the proper documentation and verification that the consent has been given.

A. Murmurs are usually related to valve dysfunctions, such as tricuspid or pulmonic valve issues, which may or may not be present in right-sided heart failure.
B. Crackles (or rales) are more commonly associated with left-sided heart failure. They result from fluid accumulation in the lungs (pulmonary congestion) due to the heart's inability to handle the blood returning from the lungs.

C. Chest pain can occur in various cardiac conditions but is not a hallmark symptom of right-sided heart failure. It might be present if there are underlying coronary artery disease issues or other conditions, but it is not directly indicative of right-sided heart failure.
D. Peripheral edema is a classic finding in right-sided heart failure. It results from fluid accumulation in the lower extremities due to the heart's inability to effectively pump blood to the lungs and systemic circulation, causing increased venous pressure and fluid leakage into the tissues.
