Correct Answer: C

Rationale: The correct answer is C: Hypercalcemia. Increased thirst and polyuria are symptoms of hypercalcemia, as excess calcium can lead to dehydration and increased urine output. Decreased muscle tone is also a common symptom of hypercalcemia. The lab value of Ca 8 mg/dl confirms high levels of calcium in the blood. Incorrect choices: A: Hypocalcemia - This is incorrect as the lab value of Ca 8 mg/dl indicates normal to high levels of calcium, ruling out hypocalcemia. B: Hyperkalemia - This is incorrect as the lab value of K 4 mEq/L is within normal range, ruling out hyperkalemia. D: Hypochloremia - This is incorrect as the lab value of Cl 103 mEq/L is within normal range, ruling out hypochloremia.

Correct Answer: A

Rationale: The correct answer is A because it reflects a measurable and client-centered outcome. Verbalizing feelings of anxiety indicates the client is acknowledging and addressing their emotions, which is essential in managing anxiety. Choice B is incorrect as it focuses on avoidance rather than expression of emotions. Choice C is incorrect as it doesn't specify the use of appropriate coping mechanisms. Choice D is incorrect as it suggests avoidance of seeking information, which may hinder the client's understanding and coping with the diagnosis.

Correct Answer: D

Rationale: The correct answer is D. First, the nurse should put the implant back in place using forceps and a shield for self-protection. This is important to limit the exposure to radiation for both the client and the nurse. Second, the nurse should call for help to ensure proper handling and further assistance. Standing away from the implant (choice A) does not address the immediate need to secure the implant. Picking up the implant with long-handled forceps and placing it in a lead-lined container (choice B) should only be done by trained personnel to prevent further exposure. Leaving the room and notifying the radiation therapy department immediately (choice C) delays the immediate action needed to prevent unnecessary radiation exposure.

Correct Answer: B

Rationale: The correct answer is B: Obesity. Obesity is a known risk factor for colon cancer as excess body fat, especially around the waist, can lead to inflammation and insulin resistance, increasing the likelihood of cancerous cell growth in the colon. Smoking (choice A) is more strongly associated with lung and other types of cancer, not specifically colon cancer. Heavy alcohol consumption (choice C) is linked to other types of cancer, such as liver and esophageal cancer, but not as strongly to colon cancer. Saccharin consumption (choice D) has not been definitively linked to an increased risk of colon cancer.

Correct Answer: D

Rationale: The correct answer is D because pleural effusion is the accumulation of fluid in the pleural space. When auscultating the lungs of a client with pleural effusion, the examiner would note decreased or absent breath sounds over the area where the fluid has accumulated. This is due to the fluid blocking the transmission of sound through the lungs. Pronounced breath sounds (choice A) would not be present due to the fluid obstructing the normal sound transmission. Expiratory wheezes (choice B) are associated with airway obstruction, not fluid accumulation. Friction rub (choice C) is a dry, grating sound heard with inflammation of the pleura, not specifically related to pleural effusion.
