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: Intermittent flatus and minor abdominal discomfort are not signs that would prompt the nurse to call the provider immediately. They are common and expected after surgery and anesthesia. They indicate that the client's bowel function is returning to normal.

Choice B reason: A minor headache and taking an overthe counter pain pill at home are not signs that would prompt the nurse to call the provider immediately. They are mild and manageable symptoms that may be related to stress, dehydration, or caffeine withdrawal. They do not indicate a serious complication or adverse reaction.

Choice C reason: Refusing pain medication and doing physical therapy are not signs that would prompt the nurse to call the provider immediately. They are indicators of the client's preference and motivation to recover. They may also suggest that the client's pain is wellcontrolled or tolerable.

Choice D reason: Paresthesia in the fingers and intense increasing pain in the shoulder are signs that would prompt the nurse to call the provider immediately. They are indicators of a possible nerve injury, compression, or ischemia that may result from the surgery, swelling, or hematoma. They may also indicate a worsening of the client's rheumatoid arthritis or a development of a complex regional pain syndrome. They require prompt assessment and intervention to prevent permanent damage or disability.

Choice A reason: "I will take all prescribed medications." is not a statement that demonstrates an understanding of the teaching, because it is incomplete and vague. Taking all prescribed medications is an important part of the treatment for HIV, but it does not explain why, how, or for how long the medications are needed. Taking all prescribed medications without understanding the purpose, benefits, or risks can lead to poor adherence, compliance, or outcomes.

Choice B reason: "I will only need to take HIV medications for 6 months, and then I will be cured." is not a statement that demonstrates an understanding of the teaching, because it is incorrect and unrealistic. Taking HIV medications for 6 months is not enough to treat the infection, and there is no cure for HIV. HIV is a chronic and incurable infection that requires lifelong treatment with antiretroviral drugs, which can suppress the viral load, improve the immune function, and prevent the progression to AIDS. Stopping the medications after 6 months can cause the virus to rebound, the immune system to deteriorate, and the disease to worsen.

Choice C reason: "I will have to take medications for the rest of my life." is a statement that demonstrates an understanding of the teaching, because it is accurate and realistic. Taking medications for the rest of one's life is the reality of living with HIV, as there is no cure for the infection. Taking medications for the rest of one's life can help control the infection, maintain the health, and prolong the survival of people with HIV.

Choice D reason: "I will have to be careful and avoid crowds." is not a statement that demonstrates an understanding of the teaching, because it is unnecessary and exaggerated. Being careful and avoiding crowds is not a requirement for people with HIV, as the infection is not transmitted by casual contact, such as touching, hugging, or sharing utensils. Being careful and avoiding crowds can also be detrimental to the social and emotional wellbeing of people with HIV, as it can cause isolation, stigma, or depression.
