Correct Answer: A

Rationale: The correct answer is A: New set of tracheostomy tubes and Oxygen tank. Rationale: 1. New set of tracheostomy tubes: Essential for reinserting the cannulas to secure the airway. 2. Oxygen tank: To ensure James has a stable oxygen supply while the tracheostomy tubes are being reinserted. Summary of incorrect choices: B: Theophylline and Epinephrine - These medications are not directly related to managing a dislodged tracheostomy. C: Obturator and Kelly clamp - While these are useful tools for tracheostomy care, they are not the immediate equipment needed in this emergency situation. D: Sterile saline dressing - This is not relevant for a dislodged tracheostomy; the priority is securing the airway.

Correct Answer: B

Rationale: The correct answer is B because changing habits and customs that predispose the individual to cancer is crucial in preventing cancer. This includes lifestyle changes such as quitting smoking, maintaining a healthy diet, exercising regularly, and avoiding excessive sun exposure. By modifying behaviors that increase cancer risk, individuals can significantly reduce their chances of developing cancer. A: Increasing governmental control of potential carcinogens is not the first step towards effective cancer control as individual behaviors have a more direct impact on cancer risk. C: Conducting more mass screening programs is important but not the first step as prevention through lifestyle changes takes priority. D: Educating the public and professionals about cancer is essential but changing habits is the initial crucial step in effective cancer control.

Correct Answer: B

Rationale: The correct answer is B: Abnormal sensations such as burning and numbness. In AIDS-related DSP, damage to nerves causes abnormal sensations like burning and numbness. This is due to the progressive nerve damage affecting sensory functions. Staggering gait and muscle incoordination (A) are more common in conditions affecting motor nerves. Delusional thinking (C) is not a symptom of DSP. Incontinence (D) is not typically associated with DSP but may happen in more advanced stages due to loss of sensation.

Correct Answer: C

Rationale: The correct answer is C: Increased comfort. Radiation therapy for lung cancer aims to alleviate symptoms, reduce pain, and improve quality of life. It is not typically used as a curative treatment like surgery or chemotherapy (A). It does not prevent the need for oxygen (B), as lung cancer can still affect lung function. While radiation therapy may help control the growth of cancer cells, it is not always effective in preventing cancer spread (D). Therefore, the most appropriate expectation of radiation therapy for lung cancer is increased comfort for the patient.

Correct Answer: B

Rationale: The correct answer is B: Focused assessment. In this scenario, the nurse is continuously monitoring specific aspects such as vital signs, pupils, and orientation at regular intervals, which is characteristic of a focused assessment. This type of assessment allows the nurse to gather specific data related to the client's condition and respond promptly to any changes. A: Initial assessment is conducted upon admission to establish baseline data. C: Time-lapsed reassessment involves comparing current data to previous assessments over a longer period. D: Emergency assessment is performed in urgent situations to quickly identify life-threatening issues. By systematically assessing the client's vital signs, pupils, and orientation at frequent intervals, the nurse can provide timely and appropriate care in the intensive care unit setting.
