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 woman in active labor is diagnosed with a prolapsed umbilical cord. What is the priority nursing action?
- A. Elevate the mother's hips to relieve pressure on the cord.
- B. Prepare for immediate cesarean section.
- C. Administer intravenous fluids rapidly.
- D. Perform a vaginal examination to assess cervical dilation.
Correct Answer: B
Rationale: A prolapsed umbilical cord is a medical emergency during labor because it can cause compression of the umbilical cord, leading to decreased oxygen supply to the fetus. The priority nursing action in this situation is to prepare for an immediate cesarean section. This is necessary to quickly deliver the baby and relieve pressure on the cord, preventing potential fetal distress or death. Elevating the mother's hips may help reduce pressure on the cord temporarily, but it is not the definitive treatment for a prolapsed cord. Administering intravenous fluids rapidly may be necessary, but it is not the priority intervention when the fetus is at risk due to a prolapsed cord. Performing a vaginal examination to assess cervical dilation is contraindicated in the presence of a prolapsed umbilical cord as it can further compress the cord and worsen the situation.
A postpartum client who experienced a third-degree perineal laceration expresses concerns about the healing process and potential complications. What nursing intervention should be prioritized to promote optimal wound healing?
- A. Providing perineal care using peri-bottles with warm water
- B. Instructing the client on proper peri-pad application to the incision
- C. Encouraging the use of sitz baths for pain relief and wound cleansing
- D. Monitoring the incision site for signs of infection or dehiscence
Correct Answer: D
Rationale: Third-degree perineal lacerations are significant injuries that require careful monitoring for signs of infection or wound dehiscence, which are potential complications that could hinder optimal wound healing. Signs of infection may include increased redness, warmth, swelling, pain, and purulent drainage from the wound site. Dehiscence refers to the separation of the wound edges, which can be a serious complication requiring immediate attention. By closely monitoring the incision site for these signs, the nurse can promptly intervene if any complications arise, ensuring proper healing and preventing further complications. While providing perineal care, proper application of peri-pads, and encouraging sitz baths are important for comfort and cleanliness, monitoring for complications takes priority in promoting optimal wound healing in this scenario.
Which of the following conditions is characterized by inflammation of the prostate gland, typically presenting with dysuria, urinary frequency, urgency, and perineal or pelvic pain?
- A. Prostate cancer
- B. Benign prostatic hyperplasia (BPH)
- C. Prostatitis
- D. Urethritis
Correct Answer: C
Rationale: Prostatitis is characterized by inflammation of the prostate gland, leading to symptoms such as dysuria (painful urination), urinary frequency, urinary urgency, and perineal or pelvic pain. Prostate cancer, on the other hand, is characterized by the presence of malignant cells in the prostate gland and may not present with these typical symptoms. Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland that can cause urinary symptoms but is not typically associated with inflammation. Urethritis refers to inflammation of the urethra, which is a different condition and may present with symptoms such as painful urination and discharge from the urethra.
In planning for Sonny's oxygen therapy, the nurse should consider which of the following, EXCEPT
- A. need for a humidifier.
- B. length of tubing .
- C. determine the age of Excel.
- D. manner of administering oxygen, continuous or intermittent.
Correct Answer: C
Rationale: The nurse does not need to determine the age of Excel when planning for Sonny's oxygen therapy. This information is irrelevant to the specific care requirements of Sonny's oxygen therapy. Sonny's age, medical history, respiratory status, and oxygen needs are the key considerations in planning for his oxygen therapy. The nurse should focus on factors such as the need for a humidifier, length of tubing, and the manner of administering oxygen (continuous or intermittent) to ensure effective and safe delivery of oxygen therapy to Sonny.
A postpartum client expresses concern about feeling lightheaded when standing up. What should the nurse prioritize in the assessment to address this issue?
- A. Checking blood pressure
- B. Assessing for postural hypotension
- C. Evaluating hemoglobin levels
- D. Monitoring for signs of hemorrhage
Correct Answer: B
Rationale: Postural hypotension, also known as orthostatic hypotension, is a common issue postpartum and can cause lightheadedness when standing up. When a postpartum client expresses concern about feeling lightheaded, assessing for postural hypotension should be a priority. This assessment involves measuring the client's blood pressure while lying down, sitting, and standing to identify any significant drops in blood pressure upon changing positions. Identifying postural hypotension early allows for appropriate interventions to prevent potential falls and address the client's symptoms. Checking blood pressure, evaluating hemoglobin levels, and monitoring for signs of hemorrhage are also important assessments but may not directly address the specific issue of feeling lightheaded when standing up in this scenario.
