Signs and symptoms of a fecal impaction include the following:

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: 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.

Correct Answer: D

Rationale: The correct answer is D: Benign tumor. Benign tumors are noncancerous growths that do not invade nearby tissues or spread to other parts of the body. They are typically well-defined and localized, with slow growth rates. The term "nonspecific tumor" (A) is incorrect as it does not specify the nature of the tumor. "Malignant tumor" (B) refers to cancerous growths that can invade and spread, making it the opposite of a benign tumor. "Septic tumor" (C) is not a recognized medical term in relation to tumors.
