Correct Answer: A

Rationale: The correct answer is A: Platelet count, prothrombin time, and partial thromboplastin time. These parameters are essential in monitoring DIC because platelet count reflects the risk of bleeding, while prolonged prothrombin time and partial thromboplastin time indicate impaired clotting function, which is characteristic of DIC. Explanation for why other choices are incorrect: - Choice B: Blood glucose levels and WBC count are not specific indicators for DIC monitoring. - Choice C: Thrombin time, calcium levels, and potassium levels do not directly assess clotting abnormalities associated with DIC. - Choice D: While fibrinogen level is important in DIC, WBC count alone is not a specific indicator for monitoring DIC.

Correct Answer: B

Rationale: The correct answer is B: Use barrier techniques. When taking the blood pressure of a client with AIDS, using barrier techniques such as gloves and disposable equipment is crucial to prevent the transmission of the virus through blood or bodily fluids. Wearing a mask and gown (choice A) may not be necessary unless there is a risk of splashes or sprays. Washing hands thoroughly (choice C) is important, but alone may not provide sufficient protection. Choice D is incomplete.

Correct Answer: A

Rationale: The correct answer is A: Laryngeal cancer is one of the most preventable types of cancer. This is because the primary risk factors for laryngeal cancer are largely related to lifestyle choices such as smoking, excessive alcohol consumption, and exposure to certain occupational hazards. By avoiding these risk factors, individuals can significantly reduce their chances of developing laryngeal cancer. Choices B, C, and D are incorrect: B: Inhaling polluted air isn’t a risk factor for laryngeal cancer - This is incorrect as exposure to polluted air can contribute to the development of laryngeal cancer. C: Laryngeal cancer occurs primarily in women - This is incorrect as laryngeal cancer occurs more frequently in men than in women. D: Adenocarcinoma accounts for most cases of laryngeal cancer - This is incorrect as squamous cell carcinoma is the most common type of laryngeal cancer, not adenocarcin

Correct Answer: A

Rationale: The correct answer is A: Cancerous lumps. Breast self-examination aims to detect any abnormal changes in the breasts, including potential cancerous lumps. Detecting cancerous lumps early increases the chances of successful treatment and improved outcomes. Choices B, C, and D are incorrect because while changes from previous self-examinations, areas of thickness or fullness, and fibrocystic masses can be important to note, the primary goal of breast self-examination is to identify any signs of breast cancer, such as cancerous lumps.

Correct Answer: D

Rationale: The correct answer is D because polyuria is a common complication following hypophysectomy (removal of the pituitary gland). This procedure can disrupt the regulation of antidiuretic hormone (ADH), leading to excessive urination. Choice A is incorrect as decreased stress would not cause polyuria. Choice B is unlikely as the onset of diabetes mellitus is not a typical immediate postoperative complication. Choice C is incorrect as removal of the pituitary gland would disrupt hormone regulation, possibly leading to polyuria, rather than being an expected result.
