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.

Which of the following actions should be taken first when encountering a person experiencing an allergic reaction with signs of respiratory distress?
- A. Administer an epinephrine auto-injector.
- B. Position the person comfortably.
- C. Monitor vital signs.
- D. Assess the severity of the reaction.
Correct Answer: D
Rationale: The correct answer is D: Assess the severity of the reaction. This should be the first action taken because it helps determine the urgency of the situation and guides subsequent steps. Assessing the severity allows for appropriate intervention - from calling emergency services if the reaction is severe, to administering medication if necessary.
A: Administering an epinephrine auto-injector should only be done if the severity of the reaction warrants it, as it is a potent medication that can have serious side effects if used inappropriately.
B: Positioning the person comfortably is important, but assessing the severity of the reaction takes precedence to ensure prompt and appropriate care.
C: Monitoring vital signs is important, but assessing the severity of the reaction is crucial in determining the immediate course of action.
The PRIORITY nursing objective when caring a patient with a tracheostomy is _________.
- A. To increase tissue oxygenation
- B. To provide patent airway
- C. To decrease tissue oxygenation
- D. To improve ventilation
Correct Answer: B
Rationale: The correct answer is B: To provide a patent airway. When caring for a patient with a tracheostomy, ensuring a clear and unobstructed airway is the top priority to maintain adequate oxygenation and ventilation. This involves suctioning, maintaining proper tube placement, and monitoring for any signs of respiratory distress. Choices A, C, and D are incorrect as they do not address the immediate need for airway management, which is crucial for the patient's safety and well-being.
A patient presents with redness, pain, and photophobia in the left eye. Slit-lamp examination reveals ciliary injection, corneal edema, and a mid-dilated pupil with fixed reaction to light. Which of the following conditions is most likely responsible for this presentation?
- A. Anterior uveitis
- B. Acute angle-closure glaucoma
- C. Endophthalmitis
- D. Corneal abrasion
Correct Answer: A
Rationale: The correct answer is A: Anterior uveitis. This condition presents with redness, pain, and photophobia due to inflammation of the uveal tract. Ciliary injection, corneal edema, and mid-dilated pupil with fixed reaction to light are classic signs of anterior uveitis. The other choices can be ruled out based on specific findings: B: Acute angle-closure glaucoma would present with a high intraocular pressure, not fixed dilated pupil. C: Endophthalmitis typically presents with severe pain, hypopyon, and vitreous inflammation. D: Corneal abrasion would not cause ciliary injection or fixed dilated pupil.
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

- D. Disregarding the patient's cultural practices and beliefs
Correct Answer: B
Rationale: Correct Answer: B

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.
