Dengue Fever MCQ Quiz With Answers

2.

Incubation Period refers to

Time between exposure and onset of symptoms
Time between appearance of symptoms and recovery phase
Time between exposure and course of illness
Time between febrile phase and critical phase

Correct Answer

A. Time between exposure and onset of symptoms

Explanation

The incubation period refers to the time between exposure to a pathogen or a disease-causing agent and the onset of symptoms in an individual. During this period, the pathogen is multiplying within the body, but the person does not yet show any signs or symptoms of the illness. This period can vary depending on the specific disease and can range from a few hours to several days or even weeks. Understanding the incubation period is crucial in identifying and controlling the spread of infectious diseases.

Dengue fever incubation period ranges from:

1-12 days
3-14 days
14-28 days
28-32 days

Correct Answer

A. 3-14 days

Explanation

The correct answer is 3-14 days. The incubation period for dengue fever refers to the time it takes for symptoms to appear after a person has been infected with the virus. This period can vary, but typically ranges from 3 to 14 days. During this time, the virus replicates in the body and the person may not experience any symptoms. After the incubation period, symptoms such as high fever, severe headache, joint and muscle pain, and rash may occur. It is important to note that some individuals may experience a longer incubation period, up to 14 days, before symptoms appear.

To prevent fluid overload, what type of diuretic should be given to the patient?

Loop diuretic
Potassium-sparing diuretic
Osmotic diuretic
None of the above

Correct Answer

A. Loop diuretic

Explanation

Loop diuretics are the most appropriate type of diuretic to give to a patient in order to prevent fluid overload. Loop diuretics work by inhibiting the reabsorption of sodium and chloride in the loop of Henle in the kidneys, leading to increased urine production and fluid loss. This is particularly effective in conditions such as heart failure or kidney disease, where there is excessive fluid accumulation in the body. Potassium-sparing diuretics, on the other hand, help to retain potassium and are not as effective in preventing fluid overload. Osmotic diuretics are used to increase urine production in specific situations such as reducing intracranial pressure, but they are not typically used to prevent fluid overload.

What are the 3 phases of Dengue fever?

Coalescing, trivial and serious
Staging, growing and spreading
Febrile, Critical, and Convalescent
None of the above

Correct Answer

A. Febrile, Critical, and Convalescent

Explanation

The correct answer is Febrile, Critical, and Convalescent. Dengue fever is characterized by three distinct phases. The febrile phase is the initial stage, during which the infected person experiences high fever, severe headache, joint and muscle pain, and rash. The critical phase follows, where the fever subsides but can lead to complications such as plasma leakage, organ impairment, and even death. Finally, the convalescent phase occurs, where the symptoms gradually improve, and the patient recovers. These three phases are crucial for understanding the progression and management of Dengue fever.

Which mosquito species are primarily responsible for Dengue fever?

Aedes albopictus
Anopheles gambiae
Aedes aegypti mosquito
Culiseta annulata

Correct Answer

A. Aedes aegypti mosquito

Explanation

Aedes aegypti mosquitoes are primarily responsible for Dengue fever. This species of mosquito is known to transmit the Dengue virus to humans through its bites. They are commonly found in tropical and subtropical regions and are known to breed in stagnant water sources near human habitation. Aedes aegypti mosquitoes are also responsible for transmitting other diseases such as Zika, Chikungunya, and Yellow fever.

Which of the following is a symptom of Dengue?

Fever
Rash
Sever muscle and joint pains
All of the above

Correct Answer

A. All of the above

Explanation

All of the listed options are symptoms of Dengue. Dengue is a viral infection transmitted by mosquitoes. One of the main symptoms is a high fever, which is often accompanied by other symptoms such as a rash and severe muscle and joint pains. Therefore, all of the given options are correct and can be considered as symptoms of Dengue.

Which of the following are the diagnostics methods for dengue?

RT–PCR
Nucleic acid amplification tests (NAATs)
Enzyme-linked immunosorbent assays (ELISA)
All of the above

Correct Answer

A. All of the above

Explanation

RT-PCR is a diagnostic method for dengue. It stands for reverse transcription-polymerase chain reaction and is used to detect the presence of dengue virus RNA in a patient's blood. RT-PCR is a highly sensitive and specific method that can accurately identify the virus during the early stages of infection. Nucleic acid amplification tests (NAATs) are also diagnostic methods for dengue, which include RT-PCR. Enzyme-linked immunosorbent assays (ELISA) are another diagnostic method that detects the presence of dengue virus antibodies in a patient's blood. Therefore, the correct answer is "All of the above" as all three methods are used for diagnosing dengue.

Which of the following are important for dengue prevention?

Using mosquito repellents
Going outside in the evening
Keeping the doors and windows open
All of the above

Correct Answer

A. Using mosquito repellents

Explanation

Using mosquito repellents is important for dengue prevention because it helps to repel mosquitoes, which are the primary carriers of the dengue virus. Mosquito repellents contain ingredients that are effective in keeping mosquitoes away, reducing the risk of being bitten and infected with the virus. By using mosquito repellents, individuals can protect themselves and minimize the chances of contracting dengue.
