A nurse assesses an audible grating sound (crepitus) when a client with osteoarthritis moves his knees. What is the cause of this sound?

Choice A reason: Cleansing the skin routinely after soiling occurs is an effective intervention to prevent skin injury. This is because soiling from urine, feces, sweat, or wound drainage can irritate the skin and cause inflammation, infection, or breakdown. The nurse should use a gentle cleanser and warm water and pat the skin dry. The nurse should also avoid using harsh chemicals, alcohol, or perfumes on the skin.

Choice B reason: Applying moisturizer to dry areas of skin is an effective intervention to prevent skin injury. This is because dry skin is more prone to cracking, peeling, or tearing. The nurse should use a hypoallergenic moisturizer and apply it to the skin after cleansing and drying. The nurse should also avoid using products that contain alcohol, fragrances, or dyes on the skin.

Choice C reason: Using a Hoyer lift for all transfers is an effective intervention to prevent skin injury. This is because a Hoyer lift is a mechanical device that helps to lift and move the client safely and comfortably. It reduces the friction and shear on the skin by lifting the client off the bed surface and avoiding any sliding or dragging. It also prevents the nurse from injuring themselves by lifting the client manually.

Choice D reason: Massaging the client’s reddened shoulders and heels is not an effective intervention to prevent skin injury. In fact, this may worsen the skin injury by increasing the pressure and damage to the tissues. The nurse should avoid massaging any areas that are reddened, swollen, or blistered, as these are signs of pressure ulcers. The nurse should instead relieve the pressure by repositioning the client or using pressurerelieving devices, such as pillows, foam pads, or air mattresses.

Choice E reason: Repositioning the client once per shift is not an effective intervention to prevent skin injury. This is because repositioning the client once per shift is not frequent enough to prevent the development of pressure ulcers. Pressure ulcers are caused by prolonged pressure on the skin that reduces the blood flow and oxygen to the tissues. The nurse should reposition the client at least every 2 hours or more often if needed, depending on the client's condition and risk factors.

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.
