Correct Answer: B

Rationale: The correct answer is B: Human papillomavirus (HPV). HPV is the most important risk factor for cervical cancer as it is responsible for almost all cases. Step 1: HPV infection can lead to changes in cervical cells, increasing the risk of cancer. Step 2: Early detection and vaccination against HPV can prevent cervical cancer. Step 3: Other factors like late childbearing, postmenopausal bleeding, and tobacco use may be associated with increased risk but are not as directly linked to cervical cancer development.

Correct Answer: A

Rationale: The correct answer is A: Provide emotional support to the patient and her family. This is the priority as the patient has received devastating news and needs immediate support. Emotional support can help the patient cope with the diagnosis, express feelings, and make decisions. B: Implementing distraction techniques may not address the patient's emotional needs in this critical situation. C: Offering to inform the family of the diagnosis is important but not the priority at this moment. D: Teaching about maintaining a positive attitude may not be appropriate as the patient is facing a terminal illness.

Correct Answer: B

Rationale: The correct answer is B: TPN administered via a peripherally inserted central catheter. TPN provides comprehensive nutrition intravenously, bypassing the GI tract, which is important for patients unable to tolerate oral intake. A peripherally inserted central catheter allows for long-term TPN administration. A: Administration of parenteral feeds via a peripheral IV is not ideal for long-term nutrition as it may not provide complete nutrition. C: Insertion of an NG tube may not be feasible due to the tumor location and the patient's inability to tolerate oral intake. D: Maintaining NPO status and IV hydration alone may lead to malnutrition over time as it does not provide adequate nutrition.

Correct Answer: A

Rationale: The correct answer is A: Pain control. This is the main focus because the patient's quality of life should be prioritized, and managing pain is crucial for comfort and well-being in end-of-life care. Pain can significantly impact the patient's physical and emotional state. The other choices are incorrect because managing treatment complications (B) and administering treatments (E) may not be relevant if the tumor is inoperable and the patient has a short life expectancy. Interpretation of diagnostic tests (C) may not be necessary at this stage, and assistance with self-care (D) may not be the main priority compared to pain control.

Correct Answer: A

Rationale: The correct answer is A: Ineffective Airway Clearance. In a patient with AIDS and PCP, maintaining clear airways is crucial to prevent respiratory distress and hypoxia. Pneumocystis pneumonia can cause thick secretions and mucus plugging, leading to difficulty breathing. Ensuring effective airway clearance is a priority to optimize oxygenation and prevent respiratory complications. Impaired oral mucous membranes (B) and imbalanced nutrition (C) are important considerations but not as immediate as airway clearance. Activity intolerance (D) may be a concern for the patient but ensuring adequate oxygenation takes precedence.
