Which of the following imaging modalities is most appropriate for evaluating suspected pulmonary embolism (PE) in a pregnant patient?
- A. Chest X-ray
- B. Ventilation-perfusion (V/Q) scan
- C. Contrast-enhanced computed tomography (CT) pulmonary angiography
- D. Transthoracic echocardiography
Correct Answer: C
Rationale: In a pregnant patient with suspected pulmonary embolism (PE), the most appropriate imaging modality for evaluation is contrast-enhanced computed tomography (CT) pulmonary angiography. This imaging technique has been shown to be safe for the fetus when necessary, especially if the benefits of making a diagnosis outweigh the minimal risks associated with radiation exposure. It provides quick and accurate detection of PE with high sensitivity and specificity.

A patient is exposed to the hepatitis B virus (HBV) and develops immunity against future infections. Which type of immunity is primarily responsible for this protection?
- A. Passive immunity
- B. Innate immunity
- C. Humoral immunity
- D. Cell-mediated immunity
Correct Answer: C
Rationale: Humoral immunity is primarily responsible for protecting against infections by pathogens like viruses. In the case of the hepatitis B virus (HBV), the individual is exposed to the virus and develops immunity, which is typically mediated by antibodies produced by B cells. These antibodies circulate in the blood and can neutralize the virus, preventing future infections. This type of immunity is known as humoral immunity, as it involves the production of antibodies that target specific antigens, such as those present on the surface of the hepatitis B virus. In contrast, passive immunity is when antibodies are transferred from an external source, innate immunity provides immediate, non-specific defenses against pathogens, and cell-mediated immunity involves the activation of T cells to combat intracellular pathogens.
A patient presents with a yellowish-white spot on the cornea, surrounded by a ring of inflammation. Slit-lamp examination reveals branching, filamentous opacities extending from the corneal lesion. Which of the following conditions is most likely responsible for this presentation?
- A. Herpes simplex keratitis
- B. Bacterial keratitis
- C. Fungal keratitis
- D. Acanthamoeba keratitis
Correct Answer: C
Rationale: The description provided is classical for fungal keratitis. Fungal keratitis typically presents with a yellowish-white spot on the cornea, often surrounded by a ring of inflammation. Branching, filamentous opacities extending from the corneal lesion are commonly seen on slit-lamp examination in cases of fungal keratitis. This condition is often associated with risk factors such as trauma with organic material or contact lens wear. Prompt diagnosis and treatment with antifungal agents are crucial in managing fungal keratitis to prevent potential complications.
A patient asks the nurse several questions about their diagnosis and treatment options. What is the nurse's primary responsibility in responding to these questions?
- A. Provide brief and vague answers to avoid overwhelming the patient.
- B. Refer the patient to the physician for all medical-related questions.
- C. Listen actively and provide accurate, honest, and comprehensive answers.
- D. Ignore the patient's questions and focus on completing other tasks.
Correct Answer: C
Rationale: The nurse's primary responsibility in responding to a patient's questions about their diagnosis and treatment options is to listen actively and provide accurate, honest, and comprehensive answers. This approach helps build trust between the patient and the healthcare team, allows the patient to make informed decisions about their care, and ensures that the patient understands their condition and the recommended treatment plan. Providing vague answers or ignoring the patient's questions can lead to confusion, anxiety, and mistrust, which can hinder the patient's overall care and recovery. Referring the patient to the physician for all questions may be appropriate for certain medical inquiries, but the nurse plays a crucial role in educating and supporting the patient throughout their healthcare journey.
What guideline s IMPORTANT in relation to incident report( IR)? It is ______.
- A. not made part of the patient's chart
- B. placed in the nurse's 201 file
- C. filed in the nurses station
- D. filed in the Records Section of the hospital
Correct Answer: D
Rationale: Incident reports (IR) are filed in the Records Section of the hospital. It is important for incident reports to be kept in the Records Section for various reasons. By being filed in the hospital's official records, incident reports are included in the hospital's documentation of events, which is crucial for legal and quality improvement purposes. Placing IRs in the Records Section ensures that they are accessible to relevant personnel who may need to refer to them in the future for investigations, audits, or further actions related to the incidents. Keeping incident reports in a centralized location like the Records Section also helps in standardizing the process of documenting and tracking incidents, maintaining consistency and accountability within the healthcare facility.
A postpartum client who delivered preterm expresses concern about breastfeeding her premature infant. What nursing intervention should be prioritized to support successful breastfeeding in this situation?
- A. Providing education on strategies for initiating and maintaining milk supply
- B. Recommending the use of supplemental formula feedings to ensure adequate nutrition
- C. Encouraging the client to postpone breastfeeding until the infant reaches full term
- D. Referring the client to a lactation consultant for specialized support
Correct Answer: A
Rationale: Providing education on strategies for initiating and maintaining milk supply should be prioritized to support successful breastfeeding in this situation. Preterm infants can benefit significantly from breast milk due to its unique composition that supports their growth and development. Educating the client on techniques such as pumping to establish and maintain milk supply, proper latching techniques, and understanding the benefits of breastfeeding for preterm infants can help alleviate her concerns and increase her confidence in breastfeeding her premature infant. Additionally, promoting skin-to-skin contact and frequent feedings can also help stimulate milk production and foster bonding between the mother and infant. Encouraging and supporting the client with evidence-based information will be crucial in promoting successful breastfeeding outcomes for the preterm infant.
