Nursing Community Assessment Service (NCAS) Computer-Based Assessment — Questions and Answers

Question 1: A community assessment reveals a high prevalence of hypertension among Black adults in a specific US county. This is an example of:

An issue only addressed by individual clinicians
Normal population variation with no action needed
A health disparity requiring targeted community intervention (Correct answer)
A data collection error to be corrected

Correct answer: A health disparity requiring targeted community intervention

Disproportionate disease burden among a specific racial or ethnic group is a health disparity that demands targeted community-level intervention and advocacy.

Question 2: A patient's telemetry shows a heart rate of 48 bpm with regular rhythm. The patient is asymptomatic. What is the nurse's priority action?

Administer atropine per protocol
Continue monitoring and notify the physician of the finding (Correct answer)
Increase the IV fluid rate
Immediately call a code

Correct answer: Continue monitoring and notify the physician of the finding

An asymptomatic bradycardic patient should be monitored closely and the physician notified to determine if intervention is needed.

Question 3: Which concept from community health describes the process of enabling people to increase control over and improve their own health?

Health surveillance
Health empowerment / Health promotion (WHO Ottawa Charter definition) (Correct answer)
Clinical governance
Disease management

Correct answer: Health empowerment / Health promotion (WHO Ottawa Charter definition)

The WHO Ottawa Charter (1986) defines health promotion as the process of enabling people to increase control over and improve their health — emphasizing empowerment over disease treatment.

Question 4: Which community-level intervention has the strongest evidence for reducing suicide rates in the US?

Mandatory psychiatric hospitalization for all at-risk individuals
Eliminating all outpatient mental health services
General wellness campaigns
Means restriction (e.g., safe storage of firearms, bridge barriers) (Correct answer)

Correct answer: Means restriction (e.g., safe storage of firearms, bridge barriers)

Means restriction — making lethal methods less accessible — is one of the most evidence-based suicide prevention strategies at the community level.

Question 5: A community health nurse is running a smoking cessation program. Which counseling approach has the strongest evidence for increasing quit rates?

Combining pharmacotherapy (NRT, varenicline, or bupropion) with behavioral counseling (Correct answer)
Hypnotherapy as the primary intervention
Self-help pamphlets only
Brief advice alone without medication

Correct answer: Combining pharmacotherapy (NRT, varenicline, or bupropion) with behavioral counseling

Combined pharmacotherapy and behavioral counseling has the strongest evidence base for smoking cessation, with much higher quit rates than either approach alone.

Question 6: Which of the following sums up a community's basic qualities?

A location or shared demographic traits
A location along with values or beliefs
A specific location over time for shared objectives (Correct answer)
A region with well-defined borders

Correct answer: A specific location over time for shared objectives

A community's primary attribute is that it has evolved into a specific location over time for shared goals. This indicates that a community is a particular place where people congregate and engage in activities and goals that are shared, rather than merely a geographical area with clearly defined limits. It is centered on people's shared sense of purpose and belonging within a particular location rather than just geographical borders or demographics.

Question 7: A patient presents to the emergency department with acetaminophen overdose. Which medication should the nurse prepare to administer as an antidote?

Naloxone
Protamine sulfate
N-acetylcysteine (Correct answer)
Flumazenil

Correct answer: N-acetylcysteine

N-acetylcysteine replenishes hepatic glutathione stores, preventing the toxic acetaminophen metabolite from causing liver damage.

Question 8: Which data source provides the most objective information about mortality rates in a US community?

Community focus groups
Social media health posts
Death certificates and vital statistics records (Correct answer)
Patient satisfaction surveys

Correct answer: Death certificates and vital statistics records

Vital statistics records and death certificates are the authoritative, objective source for mortality data used in community health assessments.

Question 9: Which epidemiological concept describes the minimum proportion of a population that must be immune to prevent ongoing disease transmission?

Herd immunity threshold (Correct answer)
Attack rate
Incubation period
Case fatality rate

Correct answer: Herd immunity threshold

The herd immunity threshold is the proportion of a population that must be immune (through vaccination or prior infection) to prevent sustained disease transmission.

Question 10: A nurse prepares to collect a midstream clean-catch urine specimen. Which instruction to the patient is correct?

'Refrigerate the urine for 2 hours before bringing it to the lab.'
'Collect the first few drops of urine in the container.'
'Start urinating, stop briefly, then collect the middle portion.' (Correct answer)
'Void the entire stream into the specimen container.'

Correct answer: 'Start urinating, stop briefly, then collect the middle portion.'

The midstream technique discards the initial urine stream to flush urethral organisms, then collects the middle portion for accurate culture results.

Question 11: A community health nurse wants to assess the health status of a rural population. Which method is MOST appropriate when literacy levels are low?

In-person interviews with visual aids (Correct answer)
Online digital surveys
Written self-administered questionnaires
Complex statistical reports

Correct answer: In-person interviews with visual aids

In-person interviews using visual aids are most appropriate for populations with low literacy, ensuring accurate data collection without excluding participants.

Question 12: A nurse was doing a neighborhood assessment close to the health agency. As she drove around, the nurse noted how the community's walkways, buildings, and residents were doing. Which of the following sums up the nurse's activities the best?

A brief synopsis
A drive-through
Windshield survey (Correct answer)
An observation from the neighborhood

Correct answer: Windshield survey

In order to perform a windshield survey, the nurse must drive around the neighborhood and note the state of the homes, walkways, and residents. By doing this kind of survey, the nurse can learn more about the general health and wellbeing of the community without having to speak with people face-to-face. It gives a brief synopsis of the social and physical surroundings of the community.

Question 13: Which health behavior change model describes five stages through which individuals move when changing a health behavior: precontemplation, contemplation, preparation, action, and maintenance?

Health Belief Model
Social Cognitive Theory
PRECEDE-PROCEED Model
Transtheoretical Model (Stages of Change) (Correct answer)

Correct answer: Transtheoretical Model (Stages of Change)

The Transtheoretical Model (Prochaska and DiClemente) describes behavior change as a progression through five distinct stages from not considering change to maintaining new behavior.

Question 14: When a nurse experiences a conflict between a patient's cultural beliefs and evidence-based medical recommendations, the BEST approach is to:

Explore the patient's values and negotiate a culturally acceptable plan (Correct answer)
Refer the patient to a cultural liaison and withdraw from the case
Document the conflict and defer to the physician for resolution
Prioritize medical evidence and educate the patient until they comply

Correct answer: Explore the patient's values and negotiate a culturally acceptable plan

Culturally competent ethical practice involves exploring beliefs, providing education, and collaboratively developing a mutually acceptable care plan.

Question 15: Which antihypertensive medication class is considered first-line therapy for patients with both hypertension and type 2 diabetes due to its additional renal protective effects?

Non-dihydropyridine calcium channel blockers
Loop diuretics
Beta-blockers
ACE inhibitors (Correct answer)

Correct answer: ACE inhibitors

ACE inhibitors reduce intraglomerular pressure and proteinuria, making them preferred antihypertensives for diabetic patients to slow progression of diabetic nephropathy.

Question 16: Which of the following best describes 'upstream' interventions in health promotion?

Screening individuals for early disease detection
Treating disease after onset with medications
Addressing the root social, economic, and environmental determinants of health rather than individual symptoms (Correct answer)
Providing acute care in emergency settings

Correct answer: Addressing the root social, economic, and environmental determinants of health rather than individual symptoms

Upstream interventions address the fundamental social, economic, and environmental conditions — like poverty, housing, or food access — that create health problems in the first place.

Question 17: Which of the following best illustrates how demographic characteristics and health requirements are related?

High earners frequently experience nutritional issues as a result of their dietary choices.
A lower educational attainment is linked to more practices that promote health.
Religion may imply ideas about nutrition, healthcare, and the use of contraception. (Correct answer)
Young adult men, who make up the bulk of the population, assist in identifying the most critical service agencies.

Correct answer: Religion may imply ideas about nutrition, healthcare, and the use of contraception.

Beliefs and attitudes about contraception, healthcare, and dietary choices can be influenced by religion. A person's health needs may be impacted by the particular rules or teachings that diverse religions have for these matters. For instance, the use of contraception may be discouraged by some religions, which increases the need for reproductive health care. Similarly, dietary preferences or limits may be imposed by religious beliefs, which may have an impact on a person's nutritional requirements.

Question 18: A community nurse is counseling a patient who was exposed to hepatitis B through a needle stick. Which post-exposure prophylaxis is recommended for an unvaccinated individual?

Antiviral medications only
Prophylactic antibiotics and observation only
Hepatitis B vaccine series alone started within 1 week
Hepatitis B immune globulin (HBIG) plus initiation of the hepatitis B vaccine series within 24 hours (Correct answer)

Correct answer: Hepatitis B immune globulin (HBIG) plus initiation of the hepatitis B vaccine series within 24 hours

Unvaccinated individuals exposed to hepatitis B should receive HBIG for immediate passive immunity plus start the hepatitis B vaccine series within 24 hours of exposure.

Question 19: A community nurse calculates the incidence rate of Type 2 diabetes in a town. Incidence rate specifically measures:

The ratio of disease to healthy individuals
New cases of a disease in a population over a specific time period (Correct answer)
Total existing cases of a disease at one point in time
The mortality rate from a specific disease

Correct answer: New cases of a disease in a population over a specific time period

Incidence rate measures the number of NEW cases of a disease arising in a defined population during a specified period.

Question 20: A nurse is using the PRECEDE-PROCEED model to plan a community obesity prevention program. In the PRECEDE phase, the nurse should FIRST:

Secure funding for the program
Evaluate program outcomes
Implement the educational intervention
Conduct a social assessment to identify quality of life concerns of the target community (Correct answer)

Correct answer: Conduct a social assessment to identify quality of life concerns of the target community

The PRECEDE phase begins with a social assessment of the community's quality of life concerns to ensure the program addresses real community priorities from the start.

Question 21: Which level of the socio-ecological model addresses policies and regulations that influence health behavior across entire populations?

Individual level
Community level
Policy/enabling environment level (Correct answer)
Interpersonal level

Correct answer: Policy/enabling environment level

The policy or enabling environment level of the socio-ecological model addresses laws, regulations, and institutional policies that create structural conditions affecting population health.

Question 22: Which assessment finding is most consistent with dehydration in an adult patient?

Poor skin turgor, concentrated urine, tachycardia (Correct answer)
Bounding pulse, peripheral edema
Bradycardia, hypertension, weight gain
Crackles in lung bases, jugular vein distension

Correct answer: Poor skin turgor, concentrated urine, tachycardia

Dehydration presents with poor skin turgor, dark concentrated urine, and tachycardia as the body compensates for reduced circulating volume.

Question 23: Which statement by a patient indicates a correct understanding of incentive spirometry use?

'I will use it only when I feel short of breath.'
'I will inhale slowly and deeply to raise the ball or piston.' (Correct answer)
'I should exhale forcefully into the device.'
'I will use it once a day after meals.'

Correct answer: 'I will inhale slowly and deeply to raise the ball or piston.'

Incentive spirometry requires slow, sustained maximal inspiration to fully expand the lungs and prevent atelectasis.

Question 24: The community nurse is assessing the effectiveness of a vaccination campaign against influenza. Which metric BEST evaluates campaign effectiveness?

Media impressions from campaign advertising
Number of vaccine doses purchased
Influenza vaccination coverage rate in the target population (Correct answer)
Number of health care workers trained

Correct answer: Influenza vaccination coverage rate in the target population

Vaccination coverage rate — the percentage of the target population that received the vaccine — directly measures the immunization campaign's reach and effectiveness.

Question 25: Which of the following is an example of PRIMARY prevention identified during a community health assessment?

Managing chronic diabetes with insulin
Implementing school-based HPV vaccination programs (Correct answer)
Providing chemotherapy for cancer patients
Screening for early-stage hypertension

Correct answer: Implementing school-based HPV vaccination programs

Primary prevention prevents disease before it occurs; school-based vaccination programs prevent HPV infection and HPV-related cancers from developing.

Question 26: During a community health assessment, a nurse identifies that 30% of residents lack health insurance. This finding is best classified as which type of community health determinant?

Biological determinant
Genetic risk factor
Environmental toxin
Social determinant of health (Correct answer)

Correct answer: Social determinant of health

Lack of health insurance is a social determinant of health, reflecting economic and policy conditions that affect access to care.

Question 27: A nurse believes a patient's advance directive conflicts with what the family wants. The nurse's BEST action is to:

Request a new psychiatric evaluation to reassess patient competence
Follow the family's wishes as the primary decision-makers
Honor the advance directive as it reflects the patient's autonomous wishes (Correct answer)
Defer entirely to the physician to resolve the conflict

Correct answer: Honor the advance directive as it reflects the patient's autonomous wishes

A valid advance directive represents the patient's autonomous pre-expressed wishes and takes precedence over surrogate preferences.

Question 28: Which evidence-based therapy is MOST recommended by clinical guidelines for post-traumatic stress disorder (PTSD) treatment?

Benzodiazepine therapy as first line
Supportive counseling without trauma processing
Trauma-focused cognitive behavioral therapy (TF-CBT) or prolonged exposure therapy (Correct answer)
Isolation and rest only

Correct answer: Trauma-focused cognitive behavioral therapy (TF-CBT) or prolonged exposure therapy

Trauma-focused CBT and prolonged exposure therapy are recommended as first-line evidence-based treatments for PTSD by VA/DoD and APA clinical practice guidelines.

Question 29: Which vaccine-preventable disease is characterized by a prodrome of Koplik's spots followed by a maculopapular rash spreading from head to trunk?

Rubella
Varicella (chickenpox)
Roseola
Measles (rubeola) (Correct answer)

Correct answer: Measles (rubeola)

Koplik's spots (bluish-white spots on the buccal mucosa) followed by a cephalocaudal maculopapular rash are classic presentations of measles.

Question 30: A terminally ill patient asks the community nurse not to tell family members about the prognosis. The nurse should:

Honor the patient's request and maintain confidentiality
Inform the family anyway because they need to plan for caregiving
Encourage the patient to tell the family but respect the final decision (Correct answer)
Refer the decision to the attending physician

Correct answer: Encourage the patient to tell the family but respect the final decision

While respecting confidentiality, the nurse may provide therapeutic communication to encourage disclosure while ultimately honoring the patient's autonomous decision.
