Pediculosis causes symptoms such as

Correct Answer: A

Rationale: The correct answer is A: Itching and rashes. Pediculosis is an infestation of lice that typically causes itching due to the lice feeding on blood and laying eggs on the scalp. Rashes may also develop from scratching the itchy areas. Choice B, acne and lesions, is incorrect because lice infestation does not typically cause acne-like lesions. Choice C, cuts and abrasions, is incorrect as lice infestation does not directly cause cuts or abrasions. Choice D, boils and abscesses, is incorrect because these are not common symptoms of pediculosis.

Correct Answer: D

Rationale: The correct answer is D: Abdominal cramps and vomiting. Fecal impaction causes a blockage in the colon, leading to symptoms like abdominal cramps due to increased pressure and vomiting from the body's attempt to expel the blockage. Urgency and black stools (Choice A) are more indicative of gastrointestinal bleeding. Urination and flatus (Choice B) are not typically associated with fecal impaction. Bleeding and itching (Choice C) are more commonly seen in conditions like hemorrhoids or anal fissures.

Correct Answer: C

Rationale: The correct answer is C: Small painless sores. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. The primary stage of syphilis typically presents as small, painless sores called chancres at the site of infection (genital area, mouth, or rectum). These sores are usually firm, round, and non-itchy. They can go unnoticed and heal on their own, but the infection progresses if left untreated. The other choices, such as A: Green-yellow discharge, B: Yellow or white discharge, and D: Warts on the genitals, are not symptoms typically associated with syphilis. Discharge colors may indicate other infections, and warts are more commonly associated with human papillomavirus (HPV) infection.

Correct Answer: D

Rationale: The correct answer is D: Sequential compression stocking. This machine helps reduce fluid buildup and improve circulation by applying sequential pressure to the legs, aiding in venous return. The other choices, A: Antiembolic plastic sleeve, B: Continuous bladder irrigation, and C: Catheter irrigation, do not specifically address reducing fluid buildup or improving circulation in the context of the question.

Correct Answer: D

Rationale: The correct answer is D: Total knee replacement. A CPM machine is commonly used post total knee replacement surgery to help improve range of motion and reduce stiffness. It facilitates gentle movement of the knee joint, preventing scar tissue formation. Choices A, B, and C are incorrect because a CPM machine is not typically used for these conditions. Total hip replacement typically does not involve the use of a CPM machine. Bursitis is usually treated with rest, ice, and anti-inflammatory medications. Phantom limb pain is managed through various therapies and medications, not CPM.
