A client with dengue fever asks the nurse about the distribution of the disease. Which statement by the nurse is accurate?
"Dengue fever is only endemic to Asia and the Pacific.”
"Over 100 countries in Africa are affected by dengue fever.”
"390 million people globally are affected by severe dengue each year.”
"Dengue fever primarily affects temperate regions.”
The Correct Answer is C
Choice A rationale:
The nurse's statement is incorrect. Dengue fever is not only endemic to Asia and the Pacific. It is a mosquito-borne viral infection that can be found in tropical and subtropical regions around the world, including parts of Africa, the Americas, the Mediterranean, and Southeast Asia.
Choice B rationale:
The nurse's statement is incorrect. While dengue fever is prevalent in many countries in Africa, it is not limited to Africa alone. It is found in multiple regions worldwide where the appropriate mosquito vectors are present.
Choice C rationale:
The nurse's statement is accurate. According to the World Health Organization (WHO), an estimated 390 million people globally are affected by severe dengue each year. Severe dengue, also known as dengue hemorrhagic fever or dengue shock syndrome, can be a life-threatening condition.
Choice D rationale:
The nurse's statement is incorrect. Dengue fever is primarily found in tropical and subtropical regions, not temperate regions. The Aedes mosquitoes, which transmit the virus, thrive in warm and humid environments, making temperate regions less conducive to dengue transmission.

Correct Answer is C
Explanation
Choice A rationale:
Anopheles mosquito is responsible for transmitting malaria, not dengue fever. Malaria is prevalent in some tropical and subtropical regions and is caused by the Plasmodium parasite.
Choice B rationale:
Culex mosquito can transmit diseases like West Nile virus and some types of encephalitis but not dengue fever.
Choice C rationale:
Aedes aegypti and Aedes albopictus mosquitoes are the primary vectors responsible for transmitting dengue fever. They thrive in subtropical and tropical regions and are most active during the day.
Choice D rationale:
Blackfly is responsible for transmitting onchocerciasis (river blindness) but not dengue fever.
Correct Answer is D
Explanation
Choice A rationale:
Administering acetaminophen for fever is a reasonable intervention for the client with dengue fever. However, it is not the priority when the platelet count is low.
Choice B rationale:
Administering a blood transfusion is not the priority intervention based solely on the platelet count of 120,000/mm3. Platelet transfusion is typically considered when the platelet count drops significantly lower, leading to bleeding complications.
Choice C rationale:
Encouraging bed rest is a reasonable intervention for a client with dengue fever to conserve energy and facilitate recovery. However, it is not the priority over monitoring for potential bleeding complications.
Choice D rationale:
Monitoring for bleeding and petechiae is the priority intervention in this case. Dengue fever can cause thrombocytopenia, leading to an increased risk of bleeding. The nurse must closely monitor the client's platelet count and assess for any signs of bleeding or petechiae to detect complications early and provide appropriate interventions.
