Correct Answer: A

Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.

Correct Answer: D

Rationale: Breast implants can interfere with mammography by potentially preventing the detection of masses. The presence of implants can obscure a clear view of breast tissue, making it difficult to identify abnormalities such as masses that may indicate breast cancer. Choices A, B, and C are incorrect because discomfort, contraindications, and dislodgment are not primary reasons why breast implants interfere with mammography. The main concern is the impedance of detecting abnormalities accurately due to the implants.

Correct Answer: A

Rationale: Cognitive-Behavioral methods of pain control aim to provide benefit by restoring the client's sense of self-control, helping the client to control symptoms, and encouraging the client to actively participate in their care. However, these methods are not intended to completely relieve all pain. These interventions focus on perception and thought, aiming to influence how one interprets events and bodily sensations. Therefore, the correct answer is that they cannot completely relieve all pain, as pain relief is often a multifaceted approach that may require additional interventions beyond Cognitive-Behavioral methods. Choices B, C, and D are correct as Cognitive-Behavioral methods are designed to empower the individual in managing their pain and improving their overall well-being.

Correct Answer: D

Rationale: Effective delegation depends on clear, concise direction that leaves no room for question or interpretation on the part of the one being delegated to. In this scenario, the most appropriate direction is to ensure the urine specimen is collected promptly and delivered to the lab immediately. Choice A is too vague and does not specify the urgency required. Choice B does not emphasize the immediate need for the specimen to be delivered. Choice C introduces unnecessary medical information that is beyond the scope of a nursing assistant and may cause confusion. Therefore, choice D is the correct answer as it provides clear instructions for immediate action without room for misunderstanding.

Correct Answer: A

Rationale: When a chest tube becomes disconnected, the priority action is to immediately reattach it to the drainage system or submerge the end in a bottle of sterile water or saline solution to reestablish a water seal. This helps prevent air from entering the pleural space and causing complications. Calling the health care provider is important but not the first action in this emergency. Instructing the client to inhale and hold his breath should be avoided as it can introduce atmospheric air into the pleural space, leading to potential issues. Clamping the chest tube is generally contraindicated, especially in cases of residual air leak or pneumothorax, as it may result in a tension pneumothorax by preventing air from escaping.
