- A. 7-12 mcg/mL
- B. 4-10 mcg/mL
- C. 10-14 mcg/mL
- D. 1-5 mcg/mL

The nurse is assessing the dental status of an 18-month-old child. How many teeth should the nurse expect to examine?
- A. 6
- B. 8
- C. 12
- D. 16
Correct Answer: C
Rationale: An 18-month-old child should have approximately 12 teeth. Children typically start getting teeth around 6 months of age. By subtracting 6 from the number of months in the child's age, you can calculate the expected number of teeth. For an 18-month-old child, 18 - 6 = 12 teeth. Therefore, the correct answer is 12 teeth. Choices A, B, and D are incorrect because they do not align with the expected dental development in an 18-month-old child.
What ethical obligations do professional nurses have according to the ANA Code of Ethics for Nurses?
- A. patients.
- B. the nursing profession.
- C. provide high-quality care.

According to the ANA Code of Ethics for Nurses, professional nurses have ethical obligations to patients (clients), the nursing profession, and providing high-quality care. These elements are fundamental principles outlined in the code of ethics to guide nurses in their practice. Choice A is correct as nurses prioritize the well-being and care of their patients. Choice B is correct as nurses are expected to uphold the values and integrity of the nursing profession. Choice C is correct as providing high-quality care is a core ethical obligation of nurses. Therefore, all the choices align with the ANA Code of Ethics for Nurses.
The client has been on vancomycin for three days. Which of the following symptoms is least concerning?
- A. nausea
- B. headache
- C. vertigo
- D. tinnitus
Correct Answer: B
Rationale: The correct answer is 'headache.' While vancomycin can cause ototoxicity leading to symptoms like tinnitus, vertigo, and nausea, headaches are not typically associated with vancomycin use. Therefore, headache is the least concerning symptom in this scenario. Nausea, vertigo, and tinnitus are more likely to be related to vancomycin ototoxicity and should be closely monitored and reported. Headache is a common symptom that may not be directly linked to vancomycin use.
The nurse receives an order to administer phenytoin through the client's J-tube. The order instructs that tube feedings are stopped at least an hour prior to administering the medication and an hour after the medication is administered. Which of the following considerations may be a reason to discuss this order with the physician?
- A. The client has a history of Type II diabetes.
- B. The client is on a continuous tube-feeding regimen.
- C. The client is on fluid restriction.
- D. The pharmacy has provided phenytoin in tablet form.
Correct Answer: B
Rationale: For a client on a continuous tube-feeding regimen, stopping tube feedings for two hours to administer this medication may compromise the client's nutritional status. This interruption can lead to inadequate nutrient intake, affecting the client's overall nutritional well-being. The other choices are less relevant in this situation. Type II diabetes does not directly impact the administration of phenytoin through a J-tube. Fluid restriction would not prevent the temporary interruption of tube feedings for medication administration. The form of phenytoin provided by the pharmacy does not impact the need to discuss the order with the physician regarding the client's continuous tube-feeding regimen.
During a report from an ER nurse about a client, the nurse identifies a statement that requires additional follow-up. Which of the following statements needs further clarification?
- A. "The client said they have been taking aspirin, but I'm not sure for how long or how much."?
- B. "The client frequently takes antacids, but they have not taken any in the last three days."?
- C. "The client stopped taking ibuprofen after developing gastric ulcers."?
- D. "The client takes Antabuse and has stopped using mouthwash."?
Correct Answer: A
Rationale: The correct answer requires further follow-up as the nurse needs to know the duration and dosage of aspirin since it can impact the patient's bleeding risk. Choice B does not require immediate follow-up as not taking antacids for three days is not critical. Choice C indicates a necessary decision made by the client to stop ibuprofen after developing gastric ulcers, hence no immediate follow-up is needed. Choice D provides important information, but the priority is to address the lack of specificity regarding the client's aspirin use, which is crucial for assessing bleeding risk and potential interactions.
