Identify the causative agent of dengue fever.
- A. Fomite
- B. Bacteria
- C. Vector
- D. Virus
Correct Answer: D
Rationale: The causative agent of dengue fever is a virus. Dengue fever is primarily transmitted to humans by the bite of infected Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus. These mosquitoes act as vectors, carrying and transmitting the dengue virus (specifically four closely related but antigenically different serotypes: DEN-1, DEN-2, DEN-3, and DEN-4) to humans during the feeding process. The virus then replicates in the human body, causing symptoms of dengue fever. Therefore, the correct answer is D. Virus.

A pregnant woman presents with a history of recurrent pregnancy losses in the second trimester. On examination, the cervix is dilated, and uterine contractions are absent. Which of the following conditions is the most likely cause of these symptoms?
- A. Ectopic pregnancy
- B. Threatened abortion
- C. Placenta previa
- D. Incompetent cervix
Correct Answer: D
Rationale: Incompetent cervix refers to a weakened cervix that is unable to support the weight of the growing fetus, leading to painless cervical dilation and second-trimester pregnancy loss. In this condition, the cervix may dilate prematurely without contractions, resulting in a painless cervical dilation. The history of recurrent second-trimester losses, along with cervical dilation and absence of uterine contractions in the presenting pregnant woman, are characteristic of incompetent cervix. Prompt recognition and management with cerclage placement can help prevent further pregnancy losses in women with incompetent cervix.
Which of the following actions is appropriate for managing a conscious patient with a foreign object lodged in the eye?
- A. Attempting to remove the object with tweezers.
- B. Rinsing the eye with sterile saline solution.
- C. Applying pressure to the eyelid to dislodge the object.
- D. Placing a bandage over the affected eye.
Correct Answer: B
Rationale: When managing a conscious patient with a foreign object lodged in the eye, the appropriate action is to rinse the eye with sterile saline solution. This helps to flush out the foreign object and reduce the risk of further injury or infection. Attempting to remove the object with tweezers or applying pressure to the eyelid can potentially cause more harm to the eye. Placing a bandage over the affected eye is not beneficial in this situation as it does not address the presence of the foreign object. Rinsing the eye with sterile saline solution is the safest and most effective initial step to take in managing a foreign object lodged in the eye.
A postpartum client presents with persistent, severe headache, photophobia, and altered mental status. Which nursing action is most appropriate?
- A. Encouraging the client to rest in a dark, quiet room
- B. Providing acetaminophen for headache relief
- C. Notifying the healthcare provider immediately
- D. Offering a massage to relieve muscle tension
Correct Answer: C
Rationale: The most appropriate nursing action when a postpartum client presents with persistent, severe headache, photophobia, and altered mental status is to notify the healthcare provider immediately. These symptoms could be indicative of serious conditions such as postpartum preeclampsia or postpartum eclampsia, both of which require prompt medical evaluation and intervention. Delaying medical attention in such cases can lead to severe complications for the mother. Therefore, it is crucial to prioritize the client's safety and well-being by quickly involving the healthcare provider for further assessment and management.

- A. Administering antipsychotic medication as ordered
- B. Encouraging the client to participate in group therapy sessions

Postpartum psychosis is a psychiatric emergency that requires prompt assessment and intervention by mental health professionals. The healthcare provider can determine the appropriate course of action, which may include hospitalization, medication management, and specialized psychiatric care. Delaying notification can lead to serious consequences for both the client and her infant, so timely intervention is essential in managing postpartum psychosis.
