A man has been admitted to the hospital unit with a medical diagnosis of chronic obstructive pulmonary disease (COPD). He is receiving supplemental oxygen at 2 L/min via a nasal cannula. Which positioning technique will best assist him with breathing?

Choice A reason: "Because it is easy to digest." is not the best response by the nurse. This is not a valid reason for giving protein supplements to a client with a bed sore. Protein supplements may or may not be easy to digest depending on the type and amount of protein and the client's digestive system. The ease of digestion is not the main goal of protein supplementation.

Choice B reason: "If you don't like it, you don't have to take it." is not the best response by the nurse. This is a dismissive and unprofessional response that does not address the client's question or concern. Protein supplements are prescribed for a reason and the client should be educated on the benefits and risks of taking or refusing them. The nurse should also respect the client's preferences and choices and offer alternatives if possible.

Choice C reason: "These supplements have nothing to do with your wound." is not the best response by the nurse. This is a false and misleading statement that contradicts the evidencebased practice of wound care. Protein supplements have a lot to do with wound healing as they provide the essential nutrients for tissue repair and regeneration. Protein deficiency can impair wound healing and increase the risk of infection and complications.

Choice D reason: "Protein has amino acids that promote wound healing." is the best response by the nurse. This is a factual and informative statement that explains the rationale for giving protein supplements to a client with a bed sore. Protein is composed of amino acids, which are the building blocks of cells and tissues. Amino acids are involved in various processes of wound healing, such as collagen synthesis, angiogenesis, and immune response. Protein supplementation can enhance wound healing and prevent protein malnutrition.

Choice A reason: A temperature of 101.3 degrees Fahrenheit is a sign of fever, which is a common symptom of infection. Clients with AIDS have a weakened immune system and are more susceptible to opportunistic infections. Fever indicates that the body is trying to fight off an infection.

Choice B reason: An oxygen saturation of 97% on room air is within the normal range and does not indicate infection. Oxygen saturation measures the percentage of hemoglobin that is bound to oxygen in the blood. A low oxygen saturation may indicate respiratory problems, such as pneumonia, which is a common infection in clients with AIDS.

Choice C reason: A respiratory rate of 22 breaths per minute is slightly above the normal range of 12 to 20 breaths per minute, but it does not necessarily indicate infection. Respiratory rate may vary depending on factors such as activity level, stress, pain, or anxiety. A high respiratory rate may indicate respiratory distress, which could be caused by infection or other conditions.

Choice D reason: Purulent drainage is a thick, yellowgreen, or brown pus that indicates infection. It may come from a wound, an abscess, or a body cavity. Purulent drainage is a sign of inflammation and infection and should be reported to the health care provider.

Choice E reason: A client's ability to ambulate 20 feet is not related to infection. Ambulation is a measure of mobility and function and may be affected by factors such as pain, fatigue, or muscle weakness. Ambulation does not reflect the presence or absence of infection.
