ATI RN Custom Exams Set 1
1. Which of the following is NOT one of the three basic areas of concern into which practical nurse management responsibilities can be categorized?
- A. Managing patients' legal affairs
- B. Managing the hypothalamus: The hypothalamus is a small area in the brain located just below the thalamus. It plays a crucial role in controlling various bodily functions, including temperature regulation, hunger, and thirst, sleep-wake cycles, and hormone regulation. The hypothalamus is also involved in the control of the autonomic nervous system and the release of hormones from the pituitary gland.
- C. Managing work center operations
- D. Managing personnel
Correct answer: A
Rationale: Managing patients' legal affairs is not a basic area of concern in practical nurse management responsibilities. The primary areas typically include managing work center operations, managing personnel, and overseeing patient care. Choice B, managing the hypothalamus, is irrelevant to nurse management responsibilities and is not a standard area of concern in this context. Choice C, managing work center operations, and Choice D, managing personnel, align more closely with the core responsibilities and concerns of practical nurse management roles.
2. Each statement is true regarding oral exposure to fermentable carbohydrates, except one. Which is the exception?
- A. Longer exposure leads to an increased risk of demineralization
- B. Longer exposure increases the opportunity for remineralization
- C. The Stephan curve illustrates pH changes within plaque after rinsing with a sugar solution
- D. The critical pH at which enamel decalcification occurs is 5.5 or less
Correct answer: B
Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.
3. A baby throws its arms out and then inward (as if embracing) in response to loud noise or when its head falls. Which reflex is this?
- A. Babinski
- B. Palmar
- C. Darwinian
- D. Moro
Correct answer: D
Rationale: The correct answer is D, Moro. The Moro reflex is an instinctual response seen in infants when they experience a sudden loss of support or loud noise. The baby will throw their arms out and then bring them back in, resembling an embrace. This reflex is important for survival as it helps the infant react to potential dangers. Choice A, Babinski, refers to the reflex where a baby's toes spread apart when the sole of the foot is stimulated. Choice B, Palmar, is related to the reflex where a baby's fingers close tightly around an object placed in their palm. Choice C, Darwinian, is not a recognized reflex in this context.
4. A young child admitted to the pediatric unit has fever, irritability, and vomiting with suspected bacterial meningitis. Which cerebrospinal fluid (CSF) result should the nurse anticipate based on these data?
- A. Decreased protein count
- B. Clear, straw-colored fluid
- C. Positive for red blood cells (RBCs)
- D. Decreased glucose level
Correct answer: D
Rationale: In bacterial meningitis, the glucose level in the cerebrospinal fluid (CSF) is typically decreased due to the increased utilization of glucose by the infecting bacteria. This metabolic change leads to a decrease in CSF glucose levels, making choice D the correct answer in this scenario. Choices A, B, and C are incorrect because bacterial meningitis usually results in an increased protein count, cloudy appearance of the CSF due to the presence of bacteria, and absence of red blood cells (RBCs) in the CSF unless there is a traumatic tap, respectively.
5. The client with a chest tube after a coronary artery bypass graft has significantly slowed drainage. What action is most important for the nurse to take?
- A. Increase the setting on the suction.
- B. Notify the provider immediately.
- C. Re-position the chest tube.
- D. Take the tubing apart to assess for clots.
Correct answer: B
Rationale: If the drainage from the chest tube decreases significantly, it may indicate a blockage by a clot, potentially leading to cardiac tamponade. The nurse's priority action should be to notify the healthcare provider immediately for further evaluation and intervention. Increasing suction, re-positioning the chest tube, or disassembling the tubing independently are not appropriate actions without healthcare provider guidance in this situation.
