Which of the following goals is the PRIMARY purpose of denitrogenation prior to anesthetic induction?
- A. Improving matching of ventilation and perfusion
- B. Increasing O2 reserve in the FRC
- C. Maximizing arterial O2 content
- D. Reducing dead space ventilation
Correct Answer: B
Rationale: Denitrogenation with 100% O2 replaces nitrogen in the functional residual capacity (FRC), increasing O2 reserve to prevent hypoxemia during apnea.

Motor vehicle crash, GCS 6, dilated pupil, contralateral weakness, next step?
- A. "Obtain a CT-scan of the head"
- B. "Administer decadron 20mg IV"
- C. "Perform endotracheal intubation"
- D. "Administer mannitol 1g/kg IV"
Correct Answer: C
Rationale: The correct next step is to perform endotracheal intubation (Choice C) in this scenario. Given the presentation of a motor vehicle crash with a GCS of 6, dilated pupil, and contralateral weakness, it indicates severe head trauma causing impending airway compromise and the need for airway protection. Intubation will secure the airway, ensure adequate oxygenation, and prevent the risk of aspiration.
Choice A (CT-scan of head) is not the immediate priority as the patient's airway needs to be secured first. Choice B (Decadron) is not indicated for acute head trauma and may even worsen brain injury. Choice D (Mannitol) may help reduce intracranial pressure, but securing the airway takes precedence in this critical situation.
2 One reason that the Health Insurance Portability and Accountability Act (HIPAA) was passed was to
- A. Make sure nursing assistants receive adequate health insurance coverage
- B. Protect privacy of health information
- C. Ensure that care procedures are performed properly
- D. Prevent abuse and neglect of residents
Correct Answer: B
Rationale: The correct answer is B: Protect privacy of health information. HIPAA was enacted to establish national standards for the protection of individuals' medical records and other personal health information. This legislation aims to safeguard the confidentiality and security of patient information, ensuring that it is not inappropriately disclosed or accessed. Choices A, C, and D are incorrect because HIPAA's primary focus is on privacy regulations rather than health insurance coverage, care procedures, or abuse prevention.
Which of the following is one way that a bariatric bed may differ from a regular bed?
- A. The bed may be lower to the floor.
- B. The bed may be narrower.
- C. The bed may not be able to be used.
- D. The bed is made for people who weigh less than average.
Correct Answer: A
Rationale: The correct answer is A: The bed may be lower to the floor. Bariatric beds are designed to support heavier individuals and are typically lower to the ground to make it easier for patients to get in and out of bed safely. This feature helps reduce the risk of falls and injuries. Choices B, C, and D are incorrect because bariatric beds are typically wider to accommodate larger bodies, they are fully functional beds that can be used, and they are specifically designed for people who weigh more than average, not less.
You are called to assist a pregnant female in the 24th week gestation period according to her due date. The pale 26-year-old patient is found supine in bed, complaining of dizziness/weakness with extreme nausea. The patient denies vaginal bleeding, amniotic fluid leakage, or abdominal pain. There are no signs of imminent birth or active labor. She reports receiving normal prenatal care with no associated problems found during the pregnancy. Her heart rate is 126-130 beats per minute; her blood pressure is 80 mmHg systolic while her skin is cool and pale. Which of the following conditions is most likely to cause the patient's presentation?
- A. Uterine rupture
- B. Spontaneous abortion
- C. Supine hypotension
- D. Placenta previa
Correct Answer: C
Rationale: The correct answer is C: Supine hypotension. When a pregnant woman lies flat on her back (supine position), the weight of the uterus can compress the inferior vena cava, reducing blood flow to the heart, leading to hypotension and decreased cardiac output. This can cause symptoms like dizziness, weakness, and nausea. In this case, the patient's symptoms of dizziness, weakness, and hypotension are consistent with supine hypotension due to compression of the vena cava. Choices A, B, and D are incorrect for this scenario because uterine rupture, spontaneous abortion, and placenta previa typically present with different symptoms and are not related to the patient's current presentation.
