Which of the following structures is responsible for the initial mechanical breakdown of food during mastication?
- A. Tongue
- B. Pharynx
- C. Salivary glands
- D. Teeth
Correct Answer: D
Rationale: The correct answer is D: Teeth. Teeth are responsible for the initial mechanical breakdown of food during mastication. Step 1: Teeth use their hard surfaces to chew and grind food into smaller pieces. Step 2: This process increases the surface area of the food, making it easier for digestive enzymes to break down. Step 3: The tongue aids in moving the food around the mouth but does not break down the food mechanically. Pharynx is responsible for swallowing, not mastication. Salivary glands produce saliva that helps in the lubrication and digestion of food, but they do not directly participate in the mechanical breakdown of food.

A nurse is conducting an admission assessment for a newly admitted patient. What aspect of cultural competence should the nurse prioritize during the assessment?
- A. Assuming that the patient shares the nurse's cultural beliefs
- B. Asking the patient about their cultural background and preferences
- C. Avoiding discussions about cultural differences to prevent discomfort
- D. Disregarding the patient's cultural practices and beliefs
Correct Answer: B
Rationale: Correct Answer: B
Rationale:
1. Asking the patient about their cultural background and preferences shows respect for their individuality and acknowledges the importance of cultural competence in providing person-centered care.
2. It allows the nurse to gain valuable insights into the patient's beliefs, values, and practices, enabling them to deliver culturally appropriate care.
3. By prioritizing this aspect, the nurse can establish rapport, build trust, and enhance communication with the patient, leading to better outcomes.
4. Choices A, C, and D are incorrect as they either involve assumptions, avoidance, or disregard for the patient's cultural background, which can lead to misunderstandings, discomfort, and ineffective care.
A patient receiving palliative care for end-stage cancer experiences intractable pain despite receiving opioid medications. What intervention should the palliative nurse prioritize to address the patient's pain?
- A. Increase the dosage of the current opioid medication.
- B. Switch to a different opioid medication with a different potency.
- C. Administer adjuvant analgesic medications to enhance pain relief.
- D. Refer the patient to a pain management specialist for evaluation.
Correct Answer: D
Rationale: The correct answer is D because referring the patient to a pain management specialist for evaluation is essential in this scenario. The specialist can conduct a comprehensive assessment to identify the underlying causes of the intractable pain and recommend a tailored pain management plan. This approach ensures a multidisciplinary approach to address the complex nature of the patient's pain.
Choice A is incorrect because simply increasing the dosage of the current opioid medication may not effectively address the underlying cause of the pain and can lead to potential side effects or opioid tolerance.
Choice B is incorrect as switching to a different opioid medication without a thorough evaluation may not guarantee better pain control and can increase the risk of adverse effects or inadequate pain relief.
Choice C is incorrect as administering adjuvant analgesic medications without addressing the root cause of the pain may not provide adequate pain relief and does not address the need for a specialized pain management plan.
Which of the following actions is recommended for managing a patient with a suspected snakebite?
- A. Applying a tourniquet proximal to the bite site.
- B. Immobilizing the affected limb at the level of the heart.
- C. Making an incision over the bite site to facilitate venom extraction.
- D. Transporting the patient to a medical facility for antivenom administration.
Correct Answer: D
Rationale: The correct answer is D: Transporting the patient to a medical facility for antivenom administration. This is recommended because antivenom is the definitive treatment for snakebites. Tourniquets (choice A) can worsen tissue damage and should be avoided. Elevating the limb (choice B) may not prevent venom spread. Making an incision (choice C) can lead to infection and increased venom absorption. Antivenom administration at a medical facility is crucial for proper management of snakebites.
During surgery, the nurse observes a sudden change in the patient's level of consciousness. What is the nurse's immediate action?
- A. Administer a reversal agent for anesthesia
- B. Document the change in the patient's chart
- C. Check the patient's vital signs
- D. Notify the anesthesia provider immediately
Correct Answer: D
Rationale: The correct immediate action for the nurse is to notify the anesthesia provider immediately (Option D). This is crucial because a sudden change in the patient's level of consciousness during surgery could indicate a serious issue related to anesthesia administration. Notifying the anesthesia provider promptly allows for quick assessment and intervention to address the underlying cause, potentially preventing complications or even saving the patient's life. Administering a reversal agent (Option A) without proper evaluation by the anesthesia provider could be dangerous. Documenting the change in the patient's chart (Option B) is important but not the most immediate action. Checking the patient's vital signs (Option C) is also important but may not provide immediate insight into the cause of the change in consciousness.
Mr. M is receiving hospice care for a terminal illness. He wants to make sure his daughter is allowed to make any decisions regarding his care should he become unable to do so. What document would permit his daughter to do this?
- A. Expressed contract
- B. Implied contract
- C. Durable power of attorney
- D. Living will
Correct Answer: C
Rationale: The correct answer is C: Durable power of attorney. This legal document allows Mr. M to appoint his daughter as his healthcare proxy, granting her the authority to make medical decisions on his behalf if he becomes incapacitated. A: Expressed contract involves clear terms agreed upon by both parties, not relevant here. B: Implied contract arises from actions rather than explicit agreement, not applicable in this situation. D: A living will outlines an individual's medical treatment preferences, but does not grant decision-making authority to another person.
