Correct Answer: B

Rationale: The nurse's priority action after noticing a sudden drop in blood pressure after administering anesthesia is to assess the patient's airway, breathing, and circulation (ABCs). This is crucial to determine the immediate cause of the sudden drop in blood pressure and to ensure the patient's safety and stability. Assessment of the ABCs will help identify any potential airway obstruction, respiratory distress, or circulatory issues that may be contributing to the drop in blood pressure. Once the assessment is done, appropriate interventions can be initiated to stabilize the patient's condition. Administering vasopressors, documenting the blood pressure readings, and notifying the anesthesiologist are important actions but assessing the ABCs takes precedence in this situation to ensure the patient's immediate needs are addressed.

Correct Answer: C

Rationale: Process evaluation focuses on assessing how well the activities and procedures are being conducted to achieve the desired outcomes. In this situation, the long waiting period in the OPD is a process issue related to the efficiency of patient flow and appointment scheduling practices. By implementing a process evaluation, the QA team can analyze and improve the workflow, identify bottlenecks causing delays, and streamline the processes to reduce waiting times for patients. This approach allows the team to make targeted improvements in the processes directly associated with the patient experience, leading to a more effective and efficient OPD operation.

Correct Answer: A

Rationale: The presentation described in the question is most consistent with anterior uveitis. Anterior uveitis, also known as iritis, is characterized by redness, pain, and photophobia in the affected eye. Slit-lamp examination typically reveals ciliary injection (reddening of the conjunctiva and episclera), corneal edema, and a mid-dilated pupil with a fixed reaction to light (miosis). This occurs due to inflammation within the anterior chamber of the eye involving the iris and ciliary body.

Correct Answer: B

Rationale: The most appropriate nursing diagnosis for the individual described is "Ineffective individual coping." This is because the individual has been facing challenges in both academic (failing math class) and personal (substance dependence) aspects of his life. The repeated failures in his math class and the substance dependence for three years indicate that he might be struggling to cope with stressors and challenges in his life effectively. By identifying this nursing diagnosis, the nurse can focus on helping the individual develop effective coping strategies to manage and overcome these difficulties.

Correct Answer: C

Rationale: Feces, urine, blood, and other body fluids are considered as vehicles of transmission in the context of communicable diseases. These substances can carry and transmit disease-causing microorganisms such as bacteria, viruses, and parasites from infected individuals to others. Through close contact or exposure to these contaminated body fluids, the pathogens can enter the body of another person and cause infection. Nurses like Nurse Keena must exercise caution and use appropriate infection control measures to prevent transmission of communicable diseases through these vehicles.
