A sign of dehydration is

Correct Answer: D

Rationale: Step-by-step rationale for why choice D (Dizziness) is correct: 1. Dehydration leads to reduced blood volume, causing decreased blood flow to the brain. 2. This reduced blood flow can result in dizziness, lightheadedness, and even fainting. 3. Dizziness is a common symptom of dehydration due to impaired brain function. Summary of why other choices are incorrect: A: Moist mucous membranes - Dehydration leads to dry mucous membranes, not moist. B: An increase in urinary output - Dehydration typically causes a decrease in urine output. C: Slowed heartbeat - Dehydration usually leads to an increased heart rate to compensate for reduced blood volume, not a slowed heartbeat.

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.

Correct Answer: B

Rationale: The correct answer is B: Perseverating. Perseverating refers to the act of repeating phrases or actions persistently. This behavior is often seen in individuals with certain mental health conditions or cognitive impairments. Pillaging (A) means to loot or plunder, which is unrelated to repeating phrases. Hoarding (C) is the act of collecting and keeping items excessively, not repeating phrases. Disrupting (D) means to interrupt or disturb, which is also unrelated to the repetition of phrases. Therefore, B is the correct choice as it directly relates to the practice described in the question.
