Actual Q&A with Rationale (NSG440 Exam 4) |
Grand Canyon University
1. A community health nurse is conducting an environmental health assessment. Which
components of the ‘I-PREPARE’ mnemonic should be included in a thorough exposure
history? (Select all that apply.)
A. Investigate potential exposures
B. Present work
C. Residence
D. Environmental concerns
E. Past work
F. Activities
G. Referrals and resources
H. Educate
Correct Answer: A, B, C, D, E, F, G, H
Explanation: The I-PREPARE mnemonic is a structured tool used by nurses to gather an
environmental exposure history. It ensures that clinicians assess current and past work
settings, home environments, and community activities that may pose health risks.
,Integrating this tool into standard practice helps identify environmental determinants of
health and facilitates appropriate referrals.
2. In the context of disaster management, which activity is a primary example of the
‘Mitigation’ phase?
A. Developing a family communication plan for emergencies.
B. Conducting search and rescue operations immediately after a tornado.
C. Strengthening levees and building codes to reduce flood damage.
D. Providing psychological counseling to survivors during the recovery phase.
Correct Answer: C
Explanation: Mitigation involves proactive measures taken to prevent or reduce the
severity of a disaster’s impact. Examples include structural changes like strengthening
levees or non-structural actions like land-use planning. This phase occurs long before a
disaster happens to minimize future loss of life and property.
3. Which level of prevention is a nurse implementing when providing a diabetes management
class for patients who have already been diagnosed with Type 2 Diabetes?
A. Primary Prevention
B. Tertiary Prevention
C. Secondary Prevention
D. Primordial Prevention
, Correct Answer: B
Explanation: Tertiary prevention aims to minimize the effects of long-term disease or
disability through treatment and rehabilitation. Since the patients already have the
diagnosis, the focus is on managing the condition to prevent complications. This differs
from secondary prevention, which focuses on early detection and screening.
4. A nurse is using the epidemiological triangle to investigate an outbreak. Which factors
comprise this model? (Select all that apply.)
A. Host
B. Agent
C. Environment
D. Time
E. Vector
Correct Answer: A, B, C
Explanation: The epidemiological triangle consists of the host, the agent, and the
environment. The agent is the cause of the disease, the host is the organism harboring the
disease, and the environment includes external factors that allow transmission.
Understanding the interaction between these three elements is essential for identifying
health patterns in populations.
