The student nurse is preparing a presentation on parasitic skin infestations. What should the student include in the presentation?

Choice A reason: Visible clubbing of the fingers and toes is not a typical finding of PAD, but a sign of chronic hypoxia or lung disease. It refers to the enlargement and rounding of the nail beds due to increased blood flow to the distal tissues.

Choice B reason: Stasis ulcer on the lower leg is not a common finding of PAD, but a sign of venous insufficiency or chronic venous stasis. It refers to the breakdown of the skin due to poor venous drainage and increased pressure in the veins.

Choice C reason: Unequal peripheral pulses between the lower extremities is not a specific finding of PAD, but a sign of arterial obstruction or aneurysm. It refers to the difference in the strength or quality of the pulses palpated in the arteries of the legs.

Choice D reason: Pale edematous extremities is not a characteristic finding of PAD, but a sign of heart failure or lymphedema. It refers to the pallor and swelling of the limbs due to fluid accumulation in the interstitial spaces.

Choice E reason: Intermittent claudication is a classic finding of PAD, as it indicates the reduced blood flow and oxygen delivery to the muscles of the legs. It refers to the pain, cramping, or fatigue that occurs in the calves, thighs, or buttocks during exercise and is relieved by rest.

Choice A reason: Scabies can be cured with prescription medications that kill the mites and their eggs, such as permethrin cream or ivermectin pills. Steroid cream may help to reduce the itching and inflammation, but it does not eliminate the infection.

Choice B reason: Treatment should start as soon as possible after the diagnosis of scabies, but there is no specific time limit of 72 hours. The sooner the treatment begins, the faster the symptoms will improve and the risk of transmission will decrease.

Choice C reason: Washing clothes, towels, and sheets in hot water is an important part of the education for a client with scabies, as it helps to get rid of any mites or eggs that may have been transferred to the fabrics. The items should also be dried in a hot dryer or sealed in a plastic bag for at least 72 hours.

Choice D reason: Reducing intake of refined sugar has no effect on the risk of scabies, as scabies is not caused by dietary factors, but by a parasitic infestation of the skin by the Sarcoptes scabiei mite. The mite is transmitted by direct skin-to-skin contact or by sharing personal items with an infected person.

Choice E reason: Avoiding close contact with others until treated is another key part of the education for a client with scabies, as it helps to prevent the spread of the infection to other people. The client should also inform their household members, sexual partners, and close contacts, as they may need to be treated as well.
