Correct Answer: C

Rationale: Lamotrigine (Lamictal) is known to cause a serious rash, such as Stevens-Johnson syndrome or toxic epidermal necrolysis, which can be life-threatening. Therefore, it is crucial for patients taking Lamotrigine to be aware of this potential side effect and report any skin rashes to their healthcare provider promptly. Early detection and appropriate management are essential in preventing serious complications related to these rashes.

Correct Answer: C

Rationale: For managing a conscious patient with a dislocated shoulder, the appropriate action is to provide analgesia to help manage the pain and discomfort associated with the dislocation. Applying ice packs to the affected shoulder can also help reduce swelling and provide some relief. It is important to refrain from attempting to reduce the dislocation by pulling on the affected arm, as this can cause further damage and worsen the injury. Applying a splint to immobilize the arm in the dislocated position is also not recommended, as this can lead to complications and hinder the reduction process. Administering intravenous fluids to prevent dehydration is not directly related to managing a dislocated shoulder in a conscious patient.

Correct Answer: B

Rationale: Periodontitis is the dental condition characterized by inflammation of the gingival tissues surrounding the teeth. It is typically caused by poor oral hygiene practices, leading to plaque buildup and eventually gum disease. If left untreated, periodontitis can cause serious damage to the gum tissue and the underlying bones supporting the teeth, which can eventually result in tooth loss. Regular dental check-ups, proper oral hygiene habits, and professional cleanings are important for preventing and managing periodontitis.

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.

Correct Answer: D

Rationale: The lesson that can be gained from this scenario is that every protocol must be followed. In this situation, failure to replace the defective electric fan immediately and having a missing fire extinguisher directly led to the fire escalating and causing significant damage. By ensuring that all safety protocols and procedures are followed promptly and consistently, potential hazards and risks can be mitigated or prevented. It is crucial for employees to understand the importance of adhering to established protocols in order to maintain a safe working environment and prevent accidents or emergencies.
