Step 3: Hence, dizziness is a common sign of dehydration. Summary: A: Moist mucous membranes are not a sign of dehydration as dehydration causes dryness. B: An increase in urinary output is a sign of dehydration, not a symptom of dehydration. C: Slowed heartbeat is not a direct sign of dehydration and may occur in other conditions.

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.

Correct Answer: B

Rationale: The correct answer is B: Perseverating. Perseverating refers to the repetitive behavior of repeating phrases over and over again, often associated with certain mental health conditions. This behavior can be a result of anxiety, stress, or neurological disorders. A: Pillaging means looting or plundering, which is unrelated to the context of repeating phrases. C: Hoarding involves excessive accumulation of items and is not related to the act of repeating phrases. D: Disrupting implies causing disturbance or interruption, which does not align with the behavior of repeating phrases.
