Which of the following statements accurately describes the process of opsonization during the immune response?
- A. Opsonins facilitate the lysis of target cells by forming membrane attack complexes.
- B. Opsonins promote the phagocytosis of pathogens by coating them with proteins.
- C. Opsonins neutralize toxins produced by pathogens.
- D. Opsonins stimulate the release of histamine from mast cells.
Correct Answer: B
Rationale: Opsonization is a process in the immune response where opsonins, which are proteins such as antibodies and complement proteins, bind to pathogens such as bacteria, making them more easily recognized and engulfed by phagocytic cells like macrophages and neutrophils. This coating of pathogens by opsonins enhances the efficiency of phagocytosis, helping in the elimination of pathogens from the body. Opsonins do not facilitate cell lysis, neutralize toxins, or stimulate histamine release; their main function is to tag pathogens for phagocytosis.

In giving health teaching to the mother how to manage the patient at home, which of the following she should emphasize?
- A. Give the patient more time for self
- B. Impose strict discipline
- C. Do traditional parenting style
- D. Need for emotional support
Correct Answer: D
Rationale: When giving health teaching to the mother on how to manage the patient at home, emphasizing the need for emotional support is crucial. Taking care of a patient at home can be emotionally taxing, and the mother needs to be aware of the importance of providing emotional support to the patient. This can greatly impact the patient's overall well-being and recovery. By emphasizing the need for emotional support, the mother can create a conducive and supportive environment for the patient to heal physically, mentally, and emotionally. It also helps foster a sense of connection and positivity, which is beneficial for the patient's overall health outcomes.
The type of epidemiologic study that is used to describe a group of persons enrolled in a study who share some characteristic of interest and who are followed over a period of time to observe some health outcome is a/an:
- A. Cross-sectional study
- B. Cohort study
- C. Experimental study
- D. Case control study
Correct Answer: B
Rationale: Cohort studies are types of epidemiological studies that involve a group of individuals who share a common characteristic or experience and are followed over time to observe the development of a particular health outcome. This type of study is useful in determining the incidence of a disease, identifying risk factors, and studying the natural history of a disease. Cohort studies allow researchers to investigate the relationship between exposure and outcome by following participants forward in time. It helps in establishing causality and is particularly useful for studying rare exposures or outcomes. In contrast, cross-sectional studies involve collecting data from a population at a single point in time, experimental studies involve interventions and control groups, and case-control studies involve comparing individuals with a particular health outcome (cases) to those without the outcome (controls) retrospectively.
A patient presents with a thyroid nodule and signs of compression such as difficulty swallowing and breathing. Fine-needle aspiration biopsy reveals lymphocytic infiltration and germinal centers. Which endocrine disorder is most likely responsible for these symptoms?
- A. Hashimoto's thyroiditis
- B. Graves' disease
- C. Diabetes mellitus
- D. Thyroid nodules
Correct Answer: A
Rationale: Hashimoto's thyroiditis is an autoimmune disorder characterized by chronic inflammation of the thyroid gland. In this condition, lymphocytic infiltration and germinal centers can be seen in the thyroid tissue. This inflammation can lead to the formation of thyroid nodules and enlargement of the thyroid gland, causing symptoms such as difficulty swallowing and breathing due to compression of surrounding structures. Additionally, Hashimoto's thyroiditis can result in hypothyroidism over time, further contributing to the symptoms. Therefore, the patient in this case is most likely experiencing these symptoms due to Hashimoto's thyroiditis. Graves' disease, on the other hand, typically presents with hyperthyroidism and is less likely to manifest as compressive symptoms of the thyroid gland.
Inductive Reasoning process is applied in:
- A. Qualitative research
- B. Action research
- C. Quantitative research
- D. Applied research
Correct Answer: A
Rationale: Inductive reasoning is the process of drawing general conclusions from specific observations or examples. It is often used in qualitative research to develop theories or explanations based on the data collected. Qualitative research focuses on understanding phenomena in their natural settings and uses inductive reasoning to interpret and make sense of the data. This approach allows researchers to explore complex issues and uncover new insights by analyzing the details and patterns within the data.
Nurse Gay is assigned in the Medical Unit. She is guided that in documentation, she should use abbreviation that is ______.
- A. used automatically to save precious time.
- B. reduced to the minimum in all units.
- C. approved standard list by the hospital.
- D. not used at all because it can be misinterpreted.
Correct Answer: C
Rationale: Nurse Gay should use abbreviations that are part of an approved standard list by the hospital. Using standardized abbreviations ensures clarity, accuracy, and consistency in documentation. It helps in preventing misinterpretation, errors, and ambiguity in patient records. By following an approved list of abbreviations, healthcare professionals can communicate effectively and efficiently while maintaining patient safety and quality of care.
