Correct Answer: B

Rationale: Acute otitis media is the most likely condition responsible for this presentation. The sudden onset of severe, unilateral ear pain, diminished hearing, and purulent otorrhea are classic symptoms of acute otitis media. Otoscopic examination revealing a bulging, erythematous tympanic membrane with obscured landmarks further supports the diagnosis. The bulging of the tympanic membrane is due to the accumulation of fluid and pus behind it, causing the characteristic appearance. Treatment typically involves antibiotics to help clear the infection and relieve symptoms. If left untreated, acute otitis media can lead to complications such as perforation of the eardrum or mastoiditis.

Correct Answer: C

Rationale: The last and necessary part of any activity should involve an evaluation process. By evaluating the activity, the organizers can gather feedback on what worked well and what areas need improvement. This feedback is crucial for enhancing future activities that are similar in nature. It allows for reflections on the effectiveness of the activity, identifies strengths and weaknesses, and helps in making necessary adjustments for better outcomes in the future. Overall, evaluation ensures continuous improvement and development in organizing successful activities.

Correct Answer: B

Rationale: During the acute phase response, C-reactive protein (CRP) primarily serves to activate the complement system. CRP binds to phosphocholine on the surface of pathogens, allowing for the activation of the classical pathway of the complement system. This leads to the recruitment of immune cells, opsonization of pathogens, and enhancement of phagocytosis. The activation of the complement system by CRP plays a crucial role in the host defense against infections, aiding in the elimination of pathogens and the resolution of inflammation.

Correct Answer: D

Rationale: Quantitative research is the type of research that involves collecting numerical data, which can be easily quantified and analyzed statistically. It is characterized by its structured methodology, objectivity, and the ability to control variables to a considerable extent. In the context of a study on sleep, where data related to sleep patterns, duration, quality, etc., need to be measured and analyzed in a systematic manner, quantitative research would be the most appropriate choice. This type of research allows for a more precise understanding of the relationships and patterns within the data, providing valuable insights into the sleep-related factors being studied.

Correct Answer: A

Rationale: Nurse Cris should employ the communication technique of summarizing to successfully capture the details of the meeting. Summarizing involves condensing the information provided into a concise and organized form, which would help Nurse Cris remember and retain the key points discussed during the meeting. By summarizing the details, Nurse Cris can ensure that no important information is missed and can also confirm understanding by reflecting back the main points discussed. This technique promotes effective communication by enhancing clarity and reinforcing comprehension.
