Sputum examination is the major screening tool for pulmonary tuberculosis. Clients may sometimes receive false negative results in this exam. This means that the test is not perfect in terms of which characteristic of a diagnostic examination?
- A. Effectiveness
- B. Efficacy
- C. Specificity
- D. Sensitivity
Correct Answer: D
Rationale: Step 1: Define false negative - An individual with the disease incorrectly identified as disease-free.
Step 2: Understand sensitivity - Ability to correctly identify individuals with the disease.
Step 3: False negatives indicate low sensitivity.
Step 4: Sensitivity is a key characteristic of a diagnostic test.
Step 5: Therefore, the correct answer is D: Sensitivity.
Summary:
A: Effectiveness - Overall ability of the test to achieve its intended purpose.
B: Efficacy - Ability of the test under ideal conditions.
C: Specificity - Ability to correctly identify individuals without the disease.
D: Sensitivity - Ability to correctly identify individuals with the disease.

Where is the correct injection site for administering the DPT vaccine to an infant?
- A. Deltoid muscle
- B. Gluteal muscle
- C. Vastus lateralis muscle
- D. Forearm
Correct Answer: C
Rationale: The correct injection site for administering the DPT vaccine to an infant is the vastus lateralis muscle. This site is preferred for infants and young children because it has a larger muscle mass, reducing the risk of hitting a nerve or bone. The vastus lateralis muscle is located on the thigh, making it easily accessible and safe for injecting vaccines. It is recommended by healthcare professionals for infants due to better absorption and reduced discomfort. In contrast, the deltoid muscle is more suitable for adults, the gluteal muscle carries a risk of hitting the sciatic nerve, and the forearm lacks sufficient muscle mass for injection.
In the census of the Philippines in 1995, there were about 35,299,000 males and about 34,968,000 females. What is the sex ratio?
- A. 99.06:100
- B. 100.94:100
- C. 50.23%
- D. 49.76%
Correct Answer: B
Rationale: The sex ratio is calculated by dividing the number of males by the number of females and multiplying by 100. In this case, (35,299,000 / 34,968,000) x 100 = 100.94:100. This means for every 100 females, there are 100.94 males, indicating a slightly higher number of males.
Choice A (99.06:100) is incorrect as it suggests fewer males than females, which is not the case. Choice C (50.23%) and choice D (49.76%) are incorrect as they represent percentages rather than ratios, leading to a misleading interpretation of the data.
Which statistic can provide the most accurate reflection of the health status of a community?
- A. 1-4 year old age-specific mortality rate
- B. Infant mortality rate
- C. Swaroop's index
- D. Crude death rate
Correct Answer: C
Rationale: The correct answer is C: Swaroop's index. This index considers the age distribution of deaths, providing a more accurate reflection of the health status of a community compared to other statistics. A focuses on a specific age group, limiting the scope. B solely focuses on infant deaths, ignoring other age groups. D is a basic measure that doesn't consider age distribution, leading to potential inaccuracies in reflecting the overall health status of the community. Swaroop's index is a comprehensive indicator that considers all age groups, making it the most accurate choice for assessing the health status of a community.
To monitor clients registered in long-term regimens, such as Multi-Drug Therapy, which component will be most useful?
- A. Tally report
- B. Output report
- C. Target/client list
- D. Individual health record
Correct Answer: C
Rationale: Step 1: Target/client list is most useful as it provides a comprehensive list of clients in long-term regimens.
Step 2: It allows for easy monitoring of individual progress and adherence to treatment plans.
Step 3: Tally report (A) only provides a count, lacking specific client information.
Step 4: Output report (B) may not include all necessary client details.
Step 5: Individual health record (D) is specific to one client, not ideal for overall monitoring.
Knowing that malnutrition is a common community health issue, you decided to conduct a nutritional assessment. What population is particularly vulnerable to protein-energy malnutrition (PEM)?
- A. Pregnant women and the elderly
- B. Under 5-year-old children
- C. 1-4-year-old children
- D. School-age children
Correct Answer: B
Rationale: The correct answer is B, under 5-year-old children. They are particularly vulnerable to protein-energy malnutrition (PEM) due to their high nutritional needs for growth and development. Infants and young children have limited food intake capacity and are dependent on caregivers for proper nutrition. This age group is at a critical stage of growth, making them more susceptible to the negative impact of malnutrition on physical and cognitive development. Pregnant women and the elderly (choice A) have specific nutritional needs but are not as vulnerable to PEM as young children. Choices C and D are incorrect as 1-4-year-old children and school-age children have a lower risk of PEM compared to under 5-year-old children.
