Nokea
Which danger sign would warrant stoppage of pills?
- A. Clear vision
- B. Decrease blood pressure
- C. Simple colds
- D. Elevation of blood pressure
Correct Answer: D
Rationale: An elevation of blood pressure would warrant stoppage of pills. High blood pressure, or hypertension, in a 4-year-old child is abnormal and needs prompt medical attention. Giving pills without monitoring or stopping them if blood pressure is elevated can lead to serious health complications. It is important to address the underlying cause of high blood pressure in a child, which may require further evaluation and management by a healthcare provider.

Should the investigation of the fall go further, which of the following is the best source of factual information ?
- A. incident report.
- B. nurse's notes in the chart
- C. anecdotal record
- D. process recording
Correct Answer: A
Rationale: The incident report is the best source of factual information to investigate the fall further. Incident reports are official documents that provide a detailed account of what happened leading up to and during an incident. They include factual information such as the date, time, location, individuals involved, and details of the event. By reviewing the incident report, investigators can gather accurate information to determine the cause of the fall and any contributing factors. This document serves as an essential tool in conducting a thorough investigation into the fall and helps in identifying preventive measures to avoid similar incidents in the future.
A nurse is participating in a healthcare team meeting to discuss a patient's care plan. What is the nurse's role in interdisciplinary collaboration?
- A. Dictating decisions and delegating tasks to other team members
- B. Listening actively, contributing expertise, and sharing information
- C. Assuming a passive role and deferring to other healthcare providers
- D. Working independently without considering input from other team members
Correct Answer: B
Rationale: The nurse's role in interdisciplinary collaboration is crucial for providing comprehensive and effective patient care. By actively participating in healthcare team meetings, the nurse should listen attentively to the input of other team members, contribute their expertise, and share relevant information about the patient's condition. Collaboration involves working together towards shared goals, pooling knowledge and resources, and fostering mutual respect among team members. The nurse's active involvement in the care planning process helps ensure coordinated and patient-centered care delivery. This approach enhances communication, improves outcomes, and promotes a holistic approach to patient care.
Clients who are taught a variety of skills such as measuring blood glucose, taking blood pressure, changing dressings, and bathing infants belong to which domain of learning?
- A. Psychomotor domain
- B. Cognitive domain
- C. Social domain
- D. Affective domain Situation
Correct Answer: A
Rationale: Clients who are taught skills such as measuring blood glucose, taking blood pressure, changing dressings, and bathing infants are learning skills that involve physical movement and coordination. These activities require the integration of mental and physical skills, and they fall under the psychomotor domain of learning. In this domain, individuals develop physical skills and coordination through practice and repetition. The psychomotor domain is one of the three domains of learning, along with the cognitive domain (which involves knowledge and intellectual skills) and the affective domain (which involves emotions, values, and attitudes).
A patient presents with a sensation of fullness and pressure in the left ear, along with hearing loss and occasional tinnitus. Otoscopic examination reveals a retracted tympanic membrane with decreased mobility on pneumatic otoscopy. Which of the following conditions is most likely responsible for this presentation?
- A. Acute otitis media
- B. Otitis externa
- C. Serous otitis media (otitis media with effusion)
- D. Cholesteatoma
Correct Answer: C
Rationale: The presentation described in the question (sensation of fullness and pressure in the left ear, hearing loss, occasional tinnitus, retracted tympanic membrane with decreased mobility on pneumatic otoscopy) is suggestive of serous otitis media, also known as otitis media with effusion. Serous otitis media occurs when fluid accumulates in the middle ear without signs of infection. This buildup of fluid in the middle ear space can cause the tympanic membrane to retract and reduce its mobility on pneumatic otoscopy.
Which of the following statements accurately describes the role of dendritic cells in the immune response?
- A. Dendritic cells directly kill infected cells and tumor cells.
- B. Dendritic cells produce antibodies against pathogens.
- C. Dendritic cells activate na(cid:239)ve T cells and initiate adaptive immune responses.
- D. Dendritic cells release histamine and other inflammatory mediators.
Correct Answer: C
Rationale: Dendritic cells play a critical role in initiating adaptive immune responses by capturing antigens from pathogens, migrating to lymphoid organs, and presenting these antigens to naïve T cells. This activation of naïve T cells by dendritic cells is essential for the adaptive immune system to generate specific immune responses against pathogens. Dendritic cells act as professional antigen-presenting cells, which are specialized to capture, process, and present antigens to T cells, thereby facilitating the activation of T cells and the coordination of adaptive immune responses, such as the production of specific antibodies and the generation of memory T cells.
