What is the normal sodium level in the body?
- A. 135 to 145 milliequivalents per liter.
- B. 3 to 5 milliequivalents per liter.
- C. 135 to 145 microequivalents per liter.
- D. 3 to 5 microequivalents per liter.
Correct Answer: A
Rationale: The correct answer is A: 135 to 145 milliequivalents per liter. The normal range for sodium levels in the body is expressed in milliequivalents per liter, not microequivalents. Choice B and D provide a significantly lower range which is not within the normal values for sodium. Choice C incorrectly states 'microequivalents' instead of the correct unit 'milliequivalents'. Therefore, A is the correct answer.

Select the criteria that is accurately paired with its indication of birth weight or gestational age.
- A. Low birth weight: The neonate's weight is less than 1,500 g at the time of delivery.
- B. Appropriate for gestational age: The neonate's weight ranges from the 10th to the 90th percentile.
- C. Large for gestational age: The neonate's weight is above the 99th percentile.
- D. Small for gestational age: The neonate's weight is below the 20th percentile.
Correct Answer: B
Rationale: Appropriate for gestational age (AGA) indicates a neonate's weight ranging from the 10th to the 90th percentile. This range signifies that the baby's weight is within the normal range for their gestational age. Choices A, C, and D provide inaccurate information about the criteria and do not correctly correspond to the indicated birth weight or gestational age. Low birth weight typically refers to a weight below 2,500 g, large for gestational age above the 90th percentile, and small for gestational age below the 10th percentile.
Which statement about glaucoma is true and accurate?
- A. Acute angle-closure glaucoma is an ocular emergency.
- B. Acute angle-closure glaucoma leads to the loss of peripheral vision and tunnel vision.
- C. Primary open-angle glaucoma leads to eye pain, nausea, and vomiting, blurry vision, and halos.
- D. Bubbles are implanted to protect the retina from glaucoma.
Correct Answer: A
Rationale: The correct answer is A: 'Acute angle-closure glaucoma is an ocular emergency.' Acute angle-closure glaucoma is indeed considered an ocular emergency that requires immediate attention to prevent vision loss. Choice B is incorrect because acute angle-closure glaucoma commonly presents with symptoms like severe eye pain, headache, blurred vision, and halos around lights. Choice C is incorrect as these symptoms are more indicative of acute angle-closure glaucoma rather than primary open-angle glaucoma. Choice D is incorrect since bubbles are not typically used to protect the retina from glaucoma; treatment usually involves medications, laser therapy, or surgery to manage intraocular pressure.
You have just learned that another nurse was fired for taking photographs of patients without their permission using a cell phone and posting them on Facebook. This nurse was fired because the nurse had:
- A. Violated the law
- B. Acted in a negligent manner
- C. Not completed the proper documentation
- D. Violated an ethical principle
Correct Answer: A
Rationale: The correct answer is A: Violated the law. Taking and sharing patient photographs without consent is a violation of patient privacy laws, hence the nurse was fired for breaking the law. Choice B, acting in a negligent manner, is incorrect as the nurse's actions were intentional and not due to negligence. Choice C, not completing proper documentation, is unrelated to the situation described. Choice D, violating an ethical principle, is not specific enough as the primary reason for the nurse's termination was the legal breach regarding patient privacy.
When reinforcing teaching and instructing the patient, which basic principle of teaching should you follow?
- A. Sequence the instruction from the least complex to the most complex.
- B. Assume that the patient knows little or nothing about the topic.
- C. Tell the patient to call their significant other so you can instruct them.
- D. Use medically oriented terms so the patient will be able to speak with the doctor.
Correct Answer: A
Rationale: The correct principle of teaching to follow when reinforcing teaching and instructing the patient is to sequence the instruction from the least complex to the most complex. This approach facilitates learning by building upon simpler concepts before moving to more advanced ones. Choice B is incorrect because assuming the patient knows little or nothing about the topic may not always be accurate and can be patronizing. Choice C is incorrect as it does not focus on the direct teaching approach to the patient. Choice D is incorrect as using medically oriented terms may confuse the patient rather than facilitate understanding.
A nurse at a long-term care facility is planning a fall prevention program for the residents. Which of the following interventions should the nurse include?
- A. Apply vest restraints to residents who are confused
- B. Keep all four side rails up on beds at night
- C. Accompany residents over 85 years of age during ambulation
- D. Implement rounds every 2 hours during the day to offer toileting
Correct Answer: D
Rationale: The correct answer is to implement rounds every 2 hours during the day to offer toileting. This intervention helps prevent falls by addressing the common cause of unassisted mobility, which is the need to use the bathroom. Choice A is incorrect as restraints should not be the first choice for fall prevention due to the risk of injury and loss of independence. Choice B is incorrect because all side rails up can lead to entrapment and should only be used based on individualized assessments. Choice C may not be feasible for all residents over 85 years old and does not directly address the risk of falls.
