Pediculosis causes symptoms such as

Correct Answer: A

Rationale: The correct answer is A: Itching and rashes. Pediculosis is a condition caused by infestation of lice. Lice bites can lead to itching and skin irritation, resulting in rashes. Other choices like B: Acne and lesions, C: Cuts and abrasions, and D: Boils and abscesses are not typically associated with pediculosis. Acne is caused by blocked hair follicles, cuts and abrasions are physical injuries, and boils and abscesses are usually caused by bacterial infections. Therefore, the symptoms of itching and rashes are the most characteristic of pediculosis.

Correct Answer: D

Rationale: The correct answer is D: Abdominal cramps and vomiting. Fecal impaction can cause abdominal cramps due to the blockage of the colon. Vomiting can occur as a result of the pressure and discomfort caused by the impaction. Urgency and black stools (A) are more indicative of lower gastrointestinal issues like bleeding or inflammation. Urination and flatus (B) are not typical signs of fecal impaction. Bleeding and itching (C) are more commonly associated with hemorrhoids or anal fissures, not fecal impaction.

Correct Answer: C

Rationale: The correct answer is C: Small painless sores. Syphilis typically presents with painless sores called chancres at the site of infection. These sores are usually firm, round, and often go unnoticed. Other choices like A (Green-yellow discharge) and B (Yellow or white discharge) are more indicative of other sexually transmitted infections like gonorrhea or trichomoniasis. Choice D (Warts on the genitals) is a symptom of genital warts caused by the human papillomavirus (HPV), not syphilis.

Correct Answer: D

Rationale: The correct answer is D: Sequential compression stocking. This device helps reduce fluid buildup and improve circulation by applying sequential pressure to the legs, aiding in venous return. This promotes blood flow and prevents blood clots. A: Antiembolic plastic sleeve does not provide sequential compression, which is essential for improving circulation. B: Continuous bladder irrigation is used for clearing the bladder of clots or debris, not for reducing fluid buildup in the legs. C: Catheter irrigation is used to clear blockages in catheters, not for improving circulation in the legs. Therefore, the correct choice is D as it is specifically designed to address the issue of fluid buildup and circulation in the legs.

Correct Answer: D

Rationale: The correct answer is D: Total knee replacement. A CPM machine is used post-surgery to aid in the recovery of joint mobility and prevent stiffness after a total knee replacement. It helps in promoting circulation, reducing swelling, and improving range of motion in the knee joint. For choices A, B, and C, a CPM machine is not typically used as part of the treatment plan for total hip replacement, bursitis, or phantom limb pain.
