What is an example of Monera microorganisms?

Appeared in: WCL Staff Nurse - 2022

Explanation

The Kingdom Monera includes all prokaryotic organisms, which are single-celled and lack a true nucleus and membrane-bound organelles.
Eubacteria, also known as 'true bacteria,' are prokaryotes and therefore fall under the Kingdom Monera.
Common examples of eubacteria include E. coli and Staphylococcus, which are frequently encountered in clinical settings.

Option B: Protozoans are single-celled eukaryotes, not prokaryotes. They possess a true nucleus and membrane-bound organelles.
Option C: Invertebrates are complex, multicellular eukaryotic animals. They belong to the Kingdom Animalia.
Option D: Mosses and ferns are multicellular eukaryotic plants. They belong to the Kingdom Plantae.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of living organisms, specifically identifying examples within the Kingdom Monera as background academic context rather than a clinical decision trigger.
Understanding that bacteria (Eubacteria) are prokaryotes is fundamental for nurses to grasp how antibiotics work, as many target prokaryotic-specific structures like the cell wall or ribosomes, which differ from human (eukaryotic) cells.
This knowledge underpins infection control practices, such as sterilization and disinfection, which aim to eliminate pathogenic bacteria from medical equipment and environments.
What if? If a patient has a fungal infection (Kingdom Fungi) instead of a bacterial one, antibiotics would be ineffective. The nurse would anticipate the administration of antifungal medications, which target eukaryotic fungal cells.

How to Approach the Question

First, identify the core concept in the question: 'Monera microorganisms'.
Recall the defining characteristic of the Kingdom Monera: it consists of prokaryotic organisms (cells without a true nucleus).
Evaluate each option to determine if it is a prokaryote.
Eubacteria are known as true bacteria and are prokaryotes.
Protozoans, invertebrates, and plants (mosses/ferns) are all composed of eukaryotic cells, which excludes them from Monera.
Therefore, select the option that represents a prokaryotic organism.
