The nurse has given medication instruction to the client receiving phenyton (Dilantin). The nurse determines that the client has an adequate understanding if the client states that:
- A. “Alcohol is not contraindicated while taking this medication.”
- B. “Good oral hygiene is needed, including brushing and flossing.”
- C. “The medication dose may be self-adjusted depending on side effects.”
- D. “The morning dose of the medication should be taken before a serum drug level is drawn.”
Correct Answer: B
Rationale: The correct answer is B: "Good oral hygiene is needed, including brushing and flossing." This is because phenytoin (Dilantin) can cause gingival hyperplasia, a side effect that leads to overgrowth of gum tissue. Good oral hygiene practices, such as regular brushing and flossing, can help prevent or minimize this side effect.
Choice A is incorrect because alcohol is contraindicated while taking phenytoin as it can increase the risk of side effects and decrease the effectiveness of the medication.
Choice C is incorrect because medication doses should never be self-adjusted without consulting a healthcare provider, as this can lead to ineffective treatment or potential harm.
Choice D is incorrect because the timing of the morning dose in relation to drawing a serum drug level is not relevant to the client's understanding of medication instructions and does not address the specific side effect of gingival hyperplasia associated with phenytoin.

Hemodynamic monitoring by means of a multilumen pulmonary artery catheter can provide detailed information about:
- A. Preload
- B. Afterload
- C. Cardiac output
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D because a multilumen pulmonary artery catheter can provide detailed information about preload, afterload, and cardiac output. Preload refers to the volume of blood in the ventricles at the end of diastole, afterload is the resistance the heart has to overcome to eject blood, and cardiac output is the amount of blood pumped by the heart per minute. This catheter allows for direct measurement of these parameters by monitoring pressures in the pulmonary artery. Choices A, B, and C are incorrect individually as they do not encompass the full range of information that can be obtained with a multilumen pulmonary artery catheter.
For a client newly diagnosed with radiation-induced thrombocytopenia, the nurse should include which intervention in the plan of care?
- A. Administering aspirin if the temperature exceeds 102○1 F (38.8○0 C)
- B. inspecting the skin for petechiae once every shift
- C. providing for frequent rest periods
- D. Placing the client in strict isolation
Correct Answer: C
Rationale: The correct answer is C: providing for frequent rest periods. This intervention is essential for a client with radiation-induced thrombocytopenia to prevent further platelet depletion and reduce the risk of bleeding episodes. Rest periods help conserve energy and minimize physical exertion, which can trigger bleeding in thrombocytopenic clients.
Rationale:
1. Administering aspirin (choice A) is contraindicated in thrombocytopenia as it can further decrease platelet count and increase the risk of bleeding.
2. Inspecting the skin for petechiae (choice B) is important but not as crucial as providing rest periods in managing thrombocytopenia.
3. Placing the client in strict isolation (choice D) is not necessary for radiation-induced thrombocytopenia unless there are other specific infectious concerns.
In summary, providing frequent rest periods is the most appropriate intervention to manage radiation-induced thrombocytopenia, promoting patient
Which of the following would the nurse teach the patient is the most common site for ear infections?
- A. Outer ear
- B. Middle ear
- C. Inner ear
- D. Semicircular canal
Correct Answer: B
Rationale: The correct answer is B, Middle ear. This is because the middle ear is the most common site for ear infections due to its anatomy, including the Eustachian tube that can easily become blocked, leading to fluid buildup and infection. The outer ear (A) is less susceptible to infections, while the inner ear (C) and semicircular canal (D) are not typically involved in ear infections, as they are more related to balance and hearing functions rather than infection susceptibility.
A staff development nurse is providing an inservice for other nurses to educate them about the Nursing Interventions Classification (NIC) system. During the inservice, which statement made by one of the nurses in the room requires the staff development nurse to clarify the information provided? “This system can help medical students determine the cost of the care they provide to
- A. patients.” “If the nursing department uses this system, communication among nurses who work
- B. throughout the hospital may be enhanced.” “We could use this system to help organize orientation for new nursing employees because we can better explain the nursing interventions we use most frequently on our
- C. unit.” “The NIC system provides one way to improve safe and effective documentation in the
- D. hospital’s electronic health record.”
Correct Answer: A
Rationale: The correct answer is A because the Nursing Interventions Classification (NIC) system is not designed to help medical students determine the cost of care. The NIC system focuses on standardizing and categorizing nursing interventions to improve communication, documentation, and patient care. Choice B is incorrect because it correctly identifies one of the benefits of using the NIC system - enhancing communication among nurses. Choice C is incorrect because it suggests a valid use of the NIC system for organizing orientation and explaining nursing interventions. Choice D is incorrect because it accurately states that the NIC system can improve documentation in the electronic health record, which is one of its purposes.
A client who reports increasing difficulty swallowing, weight loss, and fatigue is diagnosed with esophageal cancer. Because this client has difficulty swallowing, the nurse should assign highest priority to:
- A. Helping the client cope with body image
- B. Maintaining a patent airway.
- C. Preventing injury.
- D. Ensuring adequate nutrition.
Correct Answer: B
Rationale: The correct answer is B: Maintaining a patent airway. This is the highest priority because the client with esophageal cancer is at risk for airway obstruction due to difficulty swallowing. Maintaining a patent airway ensures adequate oxygenation and ventilation, which are vital for the client's survival. Without a clear airway, the client may experience respiratory distress or failure. Body image, preventing injury, and ensuring adequate nutrition are important aspects of care but do not take precedence over maintaining a patent airway in this situation.
