Which practice is recommended to prevent human immune deficiency virus (HIV) transmission?

Choice A reason: "In order to avoid flareups of Raynaud's, ensure to keep cool." is not a correct answer, because it can worsen the symptoms of Raynaud's phenomenon. Raynaud's phenomenon is a condition that causes the blood vessels in the fingers and toes to narrow and spasm in response to cold or stress, resulting in reduced blood flow and color changes. Keeping cool can trigger or aggravate the spasms and decrease the blood flow.

Choice B reason: "In order to avoid flareups of Raynaud's, ensure you wear sunscreen." is not a correct answer, because it is not related to Raynaud's phenomenon. Sunscreen is a protective measure for clients with lupus, who may have increased sensitivity to ultraviolet rays and increased risk of skin damage and flareups. However, sunscreen does not prevent or treat Raynaud's phenomenon, which is caused by cold or stress, not by sun exposure.

Choice C reason: "In order to avoid flareups of Raynaud's, ensure you wear gloves in winter." is a correct answer, because it can help prevent or reduce the symptoms of Raynaud's phenomenon. Wearing gloves in winter can keep the hands warm and prevent the blood vessels from narrowing and spasming due to cold. This can improve the blood flow and prevent color changes, numbness, pain, or ulcers in the fingers.

Choice D reason: "In order to avoid flareups of Raynaud's, ensure you brush your teeth for two minutes." is not a correct answer, because it is not related to Raynaud's phenomenon. Brushing the teeth for two minutes is a good oral hygiene practice that can prevent dental problems, such as plaque, cavities, or gingivitis. However, brushing the teeth does not affect the blood vessels in the fingers and toes, nor does it prevent or treat Raynaud's phenomenon.

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.
