Question 6:

A client with dengue fever has a platelet count of 120,000/mm3. What intervention should the nurse prioritize?

A. Administering acetaminophen for fever. B. Administering a blood transfusion. C. Encouraging bed rest. D. Monitoring for bleeding and petechiae.

Answer and Explanation

Choice A:

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:

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:

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:

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.

Question 7:

The nurse is caring for multiple clients with suspected dengue fever in a hospital setting. Which personal protective equipment (PPE) should the nurse wear while providing care to these clients?

A. Gown and gloves. B. Mask and goggles. C. N95 respirator. D. Gloves and shoe covers.

Answer and Explanation

Choice A:

Gown and gloves are not the appropriate personal protective equipment (PPE) for suspected dengue fever. Dengue fever is primarily transmitted through mosquito bites, and wearing a gown is unnecessary for protection. Additionally, gloves alone may not provide adequate protection against mosquito bites.

Choice B:

The correct choice for PPE when caring for clients with suspected dengue fever is a mask and goggles. These items protect the nurse from inhaling infectious droplets and prevent transmission through the mucous membranes of the eyes. The main mode of transmission of dengue fever is through infected mosquito bites, so a mask and goggles are essential in preventing the nurse from contracting the disease.

Choice C:

The N95 respirator is designed to filter out airborne particles and is typically used in settings where there is a risk of inhaling infectious droplets, such as during procedures that generate aerosols. While it provides a high level of protection, it is not the most appropriate choice for dengue fever, which primarily spreads through mosquito bites.

Choice D:

Gloves and shoe covers are not sufficient protection against dengue fever, as the primary mode of transmission is through mosquito bites. Shoe covers are not necessary for this situation, and gloves alone may not fully prevent mosquito bites.

Question 9:

A nurse is caring for a client with dengue fever in the febrile phase. Which signs and symptoms should the nurse expect to assess?

A. Hypotension, pleural effusion, ascites. B. Altered LOC, seizures, slow HR. C. Sudden-onset fever, headache, muscle and joint pains. D. Increased vascular permeability, thrombocytopenia, hemorrhage.

Answer and Explanation

Choice A:

Hypotension, pleural effusion, and ascites are signs and symptoms associated with the severe dengue phase, also known as dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS) These symptoms occur when the disease progresses to a more severe form, characterized by plasma leakage and organ impairment.

Choice B:

Altered LOC (level of consciousness), seizures, and slow HR (heart rate) are not typical signs and symptoms of dengue fever. These symptoms may be indicative of other conditions but are not directly related to dengue fever.

Choice C:

Sudden-onset fever, headache, muscle and joint pains are the classic symptoms of dengue fever. These symptoms typically appear after an incubation period of 4 to 10 days and are followed by a febrile phase, which may last for a few days.

Choice D:

Increased vascular permeability, thrombocytopenia, and hemorrhage are characteristic features of severe dengue fever, specifically DHF or DSS. These manifestations occur due to the increased permeability of blood vessels and low platelet counts, leading to bleeding tendencies and potential shock.

Question 13:

A nurse is caring for a client with dengue fever in the critical phase. Which nursing intervention is a priority during this phase?

A. Assessing signs of bleeding and organ failure. B. Providing supplemental oxygen as needed. C. Monitoring intake and output. D. Administering antipyretics for fever control.

Answer and Explanation

Choice A:

During the critical phase of dengue fever, which typically occurs around 3-7 days after the onset of symptoms, the client is at a higher risk of developing severe bleeding and organ failure due to plasma leakage and decreased platelet counts. Assessing for signs of bleeding, such as petechiae, ecchymosis, gum bleeding, or hematuria, is essential to detect any worsening condition promptly. Additionally, monitoring for signs of organ failure, such as altered mental status, respiratory distress, or oliguria, is crucial for timely intervention and appropriate management.

Choice B:

Providing supplemental oxygen as needed may be beneficial in certain cases of dengue fever with respiratory distress or hypoxemia. However, during the critical phase, the priority is to assess for bleeding and organ failure, as these complications pose a more immediate threat to the client's life.

Choice C:

Monitoring intake and output is a crucial nursing intervention for clients with dengue fever to ensure adequate hydration and prevent dehydration. While this is essential throughout the course of the illness, it is not the priority during the critical phase when bleeding and organ failure are of greater concern.

Choice D:

Administering antipyretics for fever control may be necessary in the febrile phase of dengue fever to alleviate discomfort and manage fever. However, during the critical phase, the priority shifts to assessing for and managing potentially life-threatening complications like bleeding and organ failure.

Question 14:

A nurse is caring for a client diagnosed with dengue fever. The client's platelet count is 90,000/mm3, and hematocrit has increased by 25% from baseline. Which intervention should the nurse implement?

A. Administer aspirin for pain relief. B. Encourage ambulation to improve circulation. C. Transfuse blood products as ordered. D. Monitor SpO2 and ABGs regularly.

Answer and Explanation

Choice A:

Administering aspirin for pain relief is contraindicated in clients with dengue fever due to its anticoagulant properties, which can further increase the risk of bleeding.

Choice B:

While encouraging ambulation is generally beneficial for improving circulation in various conditions, it is not a suitable intervention during the critical phase of dengue fever when the client is experiencing severe plasma leakage and reduced platelet counts, which can lead to significant bleeding complications.

Choice C:

Transfusion of blood products, such as platelets and packed red blood cells, may be necessary in clients with dengue fever who have severe thrombocytopenia and hematocrit elevation. Platelet count below 100,000/mm3 is a common threshold for initiating platelet transfusion in dengue fever to prevent bleeding complications, and a 25% increase in hematocrit from baseline indicates hemoconcentration, which may necessitate red blood cell transfusion.

Choice D:

Monitoring SpO2 (oxygen saturation) and ABGs (arterial blood gases) regularly is important for assessing respiratory status in various conditions. However, during dengue fever, the more critical concern is the risk of bleeding and plasma leakage, making transfusion of blood products a higher priority intervention.

Question 15:

A client with dengue fever is experiencing severe plasma leakage and organ failure. The nurse observes the client has melena and hepatic damage. Which action is the nurse's priority?

A. Elevate the client's legs. B. Apply pressure to bleeding sites. C. Administer acetaminophen for pain. D. Provide supplemental oxygen.

Answer and Explanation

Choice A:

Elevating the client's legs may be helpful in certain situations to improve venous return and manage hypotension. However, during severe plasma leakage and organ failure in dengue fever, the priority is to control bleeding, and applying pressure to bleeding sites can help achieve hemostasis.

Choice B:

Applying pressure to bleeding sites is a priority intervention in clients with dengue fever experiencing severe plasma leakage and melena. This helps to control bleeding and prevent further blood loss, which is vital during the critical phase.

Choice C:

Administering acetaminophen for pain relief can be appropriate for clients with dengue fever, especially in the febrile phase when fever and discomfort are prominent. However, during the critical phase with plasma leakage and organ failure, the priority is to manage life-threatening complications like bleeding and hepatic damage.

Choice D:

Providing supplemental oxygen is essential for clients experiencing respiratory distress or hypoxemia. However, in the scenario described, the client's main priority is controlling bleeding and managing organ failure rather than addressing respiratory issues.
