1. The test used to differentiate sickle cell trait from sickle cell disease is:
- A. Sickle cell preparation.
- B. Peripheral smear.
- C. Sickledex.
- D. Hemoglobin electrophoresis
Correct answer: D
Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.
2. A client was involved in a motor vehicle accident in which the seat belt was not worn. The client is exhibiting crepitus, decreased breath sounds on the left, complains of shortness of breath, and has a respiratory rate of 34/min. Which of the following assessment findings should concern the nurse the most?
- A. temperature of 102�F and a productive cough
- B. arterial blood gases (ABGs) with a PaO2 of 92 mmHg and PaCO2 of 40 mmHg
- C. trachea deviating to the right
- D. barrel-chested appearance
Correct answer: C
Rationale: The correct answer is 'trachea deviating to the right.' A mediastinal shift is indicative of a tension pneumothorax, which is a dangerous complication seen in trauma patients with symptoms like crepitus, decreased breath sounds, shortness of breath, and tachypnea. Assessing for acute traumatic injuries is crucial in this context. Choice A, a temperature of 102�F and a productive cough, is common in pneumonia cases and not as concerning as a mediastinal shift. Choice B, ABGs with a PaO2 of 92 mmHg and PaCO2 of 40 mmHg, shows values within normal limits and does not suggest a tension pneumothorax. Choice D, a barrel-chested appearance, is typical of COPD and not directly related to the acute traumatic injury described. A tension pneumothorax is a medical emergency where air cannot escape the pleural cavity, leading to lung collapse and a mediastinal shift to the unaffected side with a downward displacement of the diaphragm.
3. With a breech presentation, the nurse must be particularly alert for which of the following?
- A. quickening
- B. ophthalmia neonatorum
- C. pica
- D. prolapsed umbilical cord
Correct answer: D
Rationale: With a breech presentation, the nurse must be particularly alert for a prolapsed umbilical cord. Prolapsed umbilical cord is a critical emergency situation where the umbilical cord descends into the vagina before the fetal presenting part, leading to compression between the presenting part and the maternal pelvis. This compression can compromise or completely cut off fetoplacental perfusion, endangering the fetus. Immediate delivery should be attempted to save the fetus. Quickening refers to fetal movements felt by the mother, ophthalmia neonatorum is an eye infection in newborns, and pica is a condition characterized by cravings for non-nutritive substances, none of which are directly related to the risks associated with a breech presentation and prolapsed umbilical cord.
4. The nurse is caring for a client with full-thickness burns to the left arm and trunk. What is the priority for this client?
- A. Pain management
- B. Airway assessment
- C. Fluid volume status monitoring
- D. Risk for infection prevention
Correct answer: C
Rationale: Correct! With full-thickness burns, there is a significant risk of fluid loss through the burn wound and fluid shift, leading to hypovolemia and shock. Monitoring and maintaining the client's fluid volume status is crucial to prevent complications like hypovolemic shock. Pain management (Option A) is essential but not the priority in this situation. While airway assessment (Option B) is crucial, it is typically assessed first in clients with respiratory distress. Preventing infection (Option D) is important but managing fluid volume status takes precedence in the initial care of a client with full-thickness burns.
5. Which action by a graduate nurse would require the charge nurse to intervene?
- A. Walking in the hallway outside the operating room without a hair covering
- B. Putting on a surgical mask, gown, and cap before entering the operating room
- C. Wearing a surgical mask into the holding area
- D. Wearing scrubs from home into the nursing station
Correct answer: A
Rationale: The correct answer is walking in the hallway outside the operating room without a hair covering. In healthcare settings, it is crucial to adhere to infection control measures, which include wearing appropriate attire to prevent the spread of pathogens. Walking in the hallway outside the operating room without a hair covering violates these infection control protocols, necessitating immediate intervention by the charge nurse. Choices B and C are incorrect because putting on surgical attire before entering the operating room and wearing a surgical mask into the holding area are both standard practices that promote patient safety and infection control. Choice D is also incorrect as wearing scrubs from home into the nursing station, while not ideal, is not a violation that warrants immediate intervention compared to breaching infection control protocols near sensitive areas like the operating room.
