Which anatomic malformations are associated with Tetralogy of Fallot?
- A. A sub-aortic septal defect, an overriding aorta, left ventricular hypertrophy, and right ventricular outflow
- B. A sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and left ventricular outflow
- C. A sub-aortic septal defect, an overriding aorta, pulmonary atresia, and right ventricular outflow
- D. A sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and right ventricular outflow
Correct Answer: D
Rationale: Tetralogy of Fallot is characterized by a combination of four heart defects: a sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and right ventricular outflow obstruction. This leads to mixing of oxygen-poor and oxygen-rich blood, resulting in cyanosis. Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not accurately describe the specific combination of anatomic malformations seen in Tetralogy of Fallot.

Which of the following is the best way to improve nursing's image?
- A. Uniforms should reflect your professionalism.
- B. Introduce yourself with your full name.
- C. Understand the essence of professional behavior in your practice.
- D. Take every opportunity to speak to the public about nursing.
Correct Answer: D
Rationale: The correct answer is D because taking every chance to engage with the public about nursing allows for the improvement of nursing's image and the promotion of the profession. Choice A is incorrect as uniforms should reflect professionalism rather than personality. Choice B is not directly related to improving nursing's image. Choice C, while important, does not directly address improving the image of nursing through public engagement.
The wound irrigation process cleanses the wound and:
- A. Reduces the potential pain in the wound region or area.
- B. Stops the spread of infection by creating a 'clean' area.
- C. Pushes extravasated blood from a hematoma into nearby healthy tissue.
- D. Allows for the introduction of medications in solution form.
Correct Answer: D
Rationale: The correct answer is D because wound irrigation allows for the introduction of medications in solution form to the wound site. Choice A is incorrect because while wound irrigation can help with pain management indirectly by promoting healing, its primary purpose is not to reduce pain directly. Choice B is incorrect as wound irrigation primarily aims to cleanse the wound and remove contaminants rather than creating a 'clean' area to stop infection spread. Choice C is incorrect because wound irrigation does not involve pushing extravasated blood from a hematoma into nearby healthy tissue; its main goal is to cleanse the wound and promote healing.
You are caring for a patient who has no cognitive functioning but only basic human functions such as opening the eyes and the sleep-wake cycle. What level of consciousness does this patient have?
- A. Obtunded
- B. A persistent vegetative state
- C. Locked-in syndrome
- D. Brain death
Correct Answer: B
Rationale: A persistent vegetative state is characterized by the absence of cognitive functioning while basic human functions like the sleep-wake cycle are retained. In this state, the patient shows reflex movements and basic responses to stimuli but lacks awareness or higher mental functions. Choices A, C, and D are incorrect because:
A) Obtunded refers to a decreased level of consciousness, not the absence of cognitive functioning.
C) Locked-in syndrome is a condition where the patient is aware and awake but cannot move or communicate due to complete paralysis of nearly all voluntary muscles except for vertical eye movements and blinking.
D) Brain death is the irreversible cessation of all brain activity, including the brainstem, leading to the loss of all functions of the brain.
Which of the following is a benefit of the U.S. health-care system?
- A. With cost savings from technology, more Americans now have health-care insurance.
- B. Quality of care has improved in the United States.
- C. Care in the United States has shifted to a prevention focus rather than an illness focus.
- D. The use of technology is projected to decrease health-care costs and improve clinical outcomes.
Correct Answer: D
Rationale: The correct answer is D because the use of technology and electronic health records is projected to decrease health-care costs and improve clinical outcomes, quality, and safety. Choice A is incorrect because it states that very few Americans have no health-care insurance, which is not a benefit of the U.S. health-care system. Choice B may be true, but it does not directly address a benefit of the health-care system. Choice C is not necessarily a benefit but rather a shift in focus, so it is also incorrect.
While administering penicillin intravenously, you notice that the patient becomes hypotensive with a bounding, rapid pulse rate. What is the first action you should take?
- A. Decrease the rate of the intravenous medication flow.
- B. Increase the rate of the intravenous medication flow.
- C. Call the doctor.
- D. Stop the intravenous flow.
Correct Answer: D
Rationale: The correct action to take when a patient becomes hypotensive with a bounding, rapid pulse rate after administering penicillin intravenously is to stop the intravenous flow immediately. This can help prevent further complications by discontinuing the administration of the medication that might be causing the adverse effects. Decreasing or increasing the rate of medication flow may not address the underlying issue of the patient's adverse reaction. While it's important to involve the healthcare provider in such situations, the immediate priority is to halt the administration of the medication.
