changed. When a sample of the milk was tasted. It was found to be contain additional water and
powder. Which of the following beste described the situation?
a. A. Adulterous
b. B. Additive

c. C. Spoiling
d. D. Fortification
The best description for the given situation would be option A, adulterous.Based on
the scenario you described, the situation can be described as the woman buying milk
that had been adulterated with water and powder.
2. A health professional is supposed to study the prevalence of stunting and associated factors among
under five children within a specified given time. What is the most appropriate study design for this
topic?
a. A. Cohort study design
b. B. Experimental study design
c. C. Case control study design
d. D. cross sectional study design.
The most appropriate study design for investigating the prevalence of stunting and
associated factors among under five children within a specific time period would be
a cross-sectional study design (option D). This design allows the researcher to collect
data on both exposure and outcome variables at a single point in time. It can provide
valuable insights into the prevalence and correlates of stunting in the target
population.
3. "X" and "y" are minority sub -groups in one of the regions of Ethiopia.If a researcher wants to
described the magnitude of a given health problem to represent the regions which sampling
method is the most appropriate?
a. Sample random sampling
b. Stratified sampling
c. Systemic random sampling
d. Cluster sampling.
If a researcher wants to accurately describe the magnitude of a given health problem
in the minority sub-groups "X" and "y" within a specific region of Ethiopia, the most
appropriate sampling method would be stratified sampling. This method ensures
that both minority sub-groups are represented proportionally to their actual
population size within the region. By dividing the target population into strata (in this
case "X" and "y"), the researcher can then randomly sample individuals from each
stratum to obtain a representative sample for analyzing the health problem.
4. Uneducated rural mothers are intended to be reached with health learning material. Which
material is appropriate to them?
a. a. Leaflet
b. b. Flip Chart
c. c. Bill Board
d. d. Poster
When it comes to reaching uneducated rural mothers with health learning
material, it's essential to consider their specific needs and access to resources.
While all the options you listed can be valuable tools, let's break down their
suitability based on the given context:
a. Leaflet: Leaflets can be effective in providing concise and visually appealing
health information. They are portable, cost-effective, and easy to distribute.
However, they may not be suitable for mothers with limited reading abilities.
b. Flip Chart: Flip charts can be highly interactive and engaging, making them
2

suitable for mothers with lower literacy levels. They allow for visuals, engaging
demonstrations, and step-by-step explanations. However, flip charts require
trained facilitators to deliver the content effectively.
c. Bill Board: Billboards are large advertising displays that can capture attention in
high-traffic areas. While they can reach a wide audience, they may not be the
most effective method for delivering detailed health information to uneducated
rural mothers.
d. Poster: Posters can be visually engaging and informative, offering key messages
and illustrations about health topics. They are inexpensive and easy to distribute.
However, posters may not provide enough detail for uneducated mothers to fully
understand complex health issues.
Considering all these factors, a combination of leaflets and flip charts might be the
most appropriate approach. Leaflets can be distributed widely to provide general
health information, while flip charts can be used during community health
sessions led by trained facilitators. This way, both visual and verbal communication
can cater to the specific needs of uneducated rural mothers, ensuring that they
receive and understand important health learning material.
5. .A researcher wanted to conduct research titled "Intention to voluntary counseling and testing for
HIV/AIDS among students of Addis Ababa University. Which model/theory best suits to the title as a
conceptual framework?
a. a. Health belief model
b. b. Social Cognitive Theory
c. c. Tans theoretical model
d. d. Theory of reasoned action
All of the models/theories mentioned could potentially be used as a conceptual
framework for the research titled "Intention to voluntary counseling and testing
for HIV/AIDS among students of Addis Ababa University." However, the most
suitable choice would depend on the specific focus and objectives of the research.
The Health Belief Model focuses on individuals' perceptions of the threat posed by
a health issue and their perceived benefits and barriers to taking action.
The Social Cognitive Theory examines how individuals' behaviors are influenced by
their environment, personal factors, and observational learning.
Tan's Theoretical Model is a comprehensive framework that incorporates various
factors such as personal attributes, social support, cultural beliefs, and public
health strategies in understanding health behaviors.
The Theory of Reasoned Action suggests that individuals' intentions to perform a
specific behavior are determined by their attitudes toward the behavior and
3
, MOE Exam for public health 2023
subjective norms.
It's essential to consider the specific research context and objectives to determine
which model/theory aligns best with the aims of the study.
6. .A researcher wanted to conduct the psychosocial behaviour of homosexual groups. Which
sampling techniques wall be most appropriate?
a. a. Judgmental sampling
b. b. Accidental sampling
c. c. Quota sampling
d. d. Snow bal sampling
.
When conducting research on the psychosocial behavior of homosexual groups,
there are a few sampling techniques that could be considered appropriate.
One technique that could be used is snowball sampling (option d). This involves
starting with a small number of individuals who meet the criteria and then asking
them to refer other individuals who also meet the criteria. This type of sampling can
be particularly helpful when studying sensitive topics or populations that may be
difficult to reach through traditional means.
Another option that could be appropriate is judgmental sampling (option a). This
involves selecting individuals who meet specific criteria based on the judgment and
expertise of the researcher. In this case, the researcher could use their knowledge
and understanding of the community and select participants accordingly.
Lastly, quota sampling (option c) could also be considered. This involves selecting
participants based on certain predetermined characteristics, such as age, gender, or
socioeconomic status. This technique allows for a representative sample to be
obtained, ensuring diversity within the group.
Accidental sampling (option b), on the other hand, is not typically recommended for
research studies as it involves selecting participants based on convenience rather
than specific criteria. It may not provide a representative sample and could
introduce bias into the results.
It's important to carefully consider the goals and requirements of the study before
selecting the most appropriate sampling technique.
7. .A researcher"A is interested in estimating average income of specific community. He took a sample
of 100 households. The same study was conducted by another researcher "B in the same
community using a sample size of 354 keeping the same level of confidence. Which of the following
better explains the width of confidence interval for these two studies?
a. a. The confidence interval estimated by A is equals to B
b. b. The error estimated in B is higher than A
c. c. The confidence interval estimated by A is wider than B
d. d. The confidence interval estimated by A is narrower than B
e.
The correct answer is c. The confidence interval estimated by researcher A is wider
