Nokea
A woman in active labor is diagnosed with postpartum hemorrhage (PPH) due to uterine atony. What is the priority nursing intervention?
- A. Massage the uterus to promote contraction.
- B. Prepare for immediate blood transfusion.
- C. Administer intravenous antibiotics.
- D. Elevate the mother's legs to promote venous return.
Correct Answer: A
Rationale: The priority nursing intervention for a woman in active labor diagnosed with postpartum hemorrhage (PPH) due to uterine atony is to massage the uterus to promote contraction. Uterine massage helps to stimulate uterine muscle tone and contraction, which can help control bleeding by reducing the size of blood vessels and promoting hemostasis. It is important to address the uterine atony promptly to prevent further blood loss and stabilize the patient's condition. Other interventions such as blood transfusion, administering antibiotics, and elevating the mother's legs can be considered based on the patient's response to the initial intervention of uterine massage.

When nurses are projected in a television advertisement as sex symbols, what APPROPRIATE action is expected from a concerned nurse?
- A. Keep your silence, it is the television station 's prerogative.
- B. Go to the street to manifest displeasure of the nurse's portrayal.
- C. Make a position paper to denounce the advertisement
- D. Condemn the issue in the radio program.
Correct Answer: C
Rationale: The most appropriate action for a concerned nurse when nurses are projected as sex symbols in a television advertisement is to make a position paper to denounce the advertisement. This approach allows the nurse to voice their concerns in a formal and professional manner. By creating a position paper, the nurse can clearly outline why the portrayal is inappropriate and advocate for more respectful representations of nursing in the media. This action is constructive, proactive, and focuses on initiating change through advocacy and education. It is a thoughtful and strategic way to address the issue and raise awareness about the importance of respecting the nursing profession.
A nurse is preparing to assist with a percutaneous endoscopic gastrostomy (PEG) tube insertion for a patient requiring long-term enteral feeding. What action should the nurse prioritize to ensure procedural success?
- A. Confirming the patient's fasting status before the PEG tube insertion
- B. Positioning the patient in a supine position with the head of the bed elevated
- C. Administering prophylactic antibiotics to prevent infection
- D. Coordinating with radiology or gastroenterology for procedural guidance Dermatology
Correct Answer: D
Rationale: Coordinating with radiology or gastroenterology for procedural guidance is crucial to ensure the success of a percutaneous endoscopic gastrostomy (PEG) tube insertion. This procedure is typically performed under endoscopic guidance to ensure proper placement of the tube into the stomach through the abdominal wall. Radiology or gastroenterology professionals are trained to perform and guide the insertion procedure, making their involvement essential for a successful outcome. Additionally, their expertise helps minimize the risk of complications during and after the PEG tube placement.
A patient presents with fever, chills, headache, and myalgia after returning from a trip to sub-Saharan Africa. Laboratory tests reveal intraerythrocytic ring forms and trophozoites on blood smear examination. Which of the following is the most likely causative agent?
- A. Plasmodium falciparum
- B. Trypanosoma cruzi
- C. Borrelia burgdorferi
- D. Leishmania donovani
Correct Answer: A
Rationale: The most likely causative agent in this scenario is Plasmodium falciparum, a protozoan parasite that causes malaria. The patient's symptoms of fever, chills, headache, and myalgia align with the typical presentation of malaria. Additionally, the presence of intraerythrocytic ring forms and trophozoites on blood smear examination is characteristic of Plasmodium species, particularly P. falciparum, which causes the most severe form of malaria.
A woman in active labor presents with a prolonged latent phase, characterized by irregular and infrequent contractions. What maternal condition should the nurse assess for that may contribute to this abnormal labor pattern?
- A. Maternal dehydration
- B. Pelvic outlet obstruction
- C. Maternal exhaustion
- D. Fetal macrosomia
Correct Answer: A
Rationale: Maternal dehydration can contribute to a prolonged latent phase during labor. Dehydration can lead to reduced blood volume and electrolyte imbalances, which can result in ineffective uterine contractions. Without adequate hydration, the uterus may not contract effectively, causing irregular and infrequent contractions. It is important for the nurse to assess the woman's hydration status and encourage her to stay hydrated during labor to help regulate contractions and progress labor.
A patient with a chronic viral infection demonstrates persistently elevated levels of CD8+ cytotoxic T cells in their blood. Which of the following mechanisms is most likely responsible for this observation?
- A. Activation-induced cell death (AICD)
- B. T cell exhaustion
- C. Thymic involution
- D. Antigenic variation
Correct Answer: B
Rationale: T cell exhaustion is a state of T cell dysfunction that arises during chronic viral infections or cancer. In the case of a chronic viral infection, the persistent exposure to viral antigens leads to continuous stimulation of CD8+ cytotoxic T cells. Over time, this sustained stimulation can lead to T cell exhaustion, characterized by the upregulation of inhibitory receptors, impaired effector functions, and reduced proliferative capacity. As a result, despite the elevated levels of CD8+ T cells in the blood, their function may be compromised, ultimately impacting the immune response against the viral infection. In contrast, activation-induced cell death (AICD) may contribute to T cell loss during chronic infections but would not explain the persistently elevated CD8+ T cell levels. Thymic involution refers to the age-related decline in thymus function, which is not directly related to the observed increase in CD8+ T cells. Antigenic
