Which of the following dental conditions is characterized by the wearing away of tooth structure due to friction from external sources such as toothbrushing or abrasive toothpaste?
- A. Dental caries
- B. Attrition
- C. Abrasion
- D. Erosion
Correct Answer: C
Rationale: The correct answer is C: Abrasion. Abrasion is the wearing away of tooth structure due to friction from external sources like toothbrushing or abrasive toothpaste. Dental caries (A) refers to tooth decay caused by bacteria. Attrition (B) is the wearing down of tooth structure due to tooth-to-tooth contact. Erosion (D) is the loss of tooth structure from acid attacks, not friction. Therefore, option C is the most fitting choice based on the description given.

During a surgical procedure, the nurse notices a sudden decrease in the patient's oxygen saturation on the monitor. What immediate action should the nurse take?
- A. Inform the surgeon and anesthesiologist
- B. Increase the flow rate of oxygen
- C. Check the endotracheal tube placement
- D. Assess the patient's respiratory status
Correct Answer: A
Rationale: The correct immediate action is to inform the surgeon and anesthesiologist (Choice A) because a sudden decrease in oxygen saturation during surgery is a critical situation that requires prompt attention from the entire surgical team. The surgeon and anesthesiologist need to be made aware of the situation so that they can assess the patient's condition and make any necessary adjustments to the surgical procedure or anesthesia delivery. Increasing the flow rate of oxygen (Choice B) may help temporarily but does not address the underlying cause of the oxygen desaturation. Checking the endotracheal tube placement (Choice C) is important but may not be the immediate priority in this critical situation. Assessing the patient's respiratory status (Choice D) is important but should be done after informing the surgeon and anesthesiologist to ensure coordinated and timely interventions.
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.
You should check the patient for suspect disturbed thought processes related to depressed metabolism and altered cardiovascular and respiratory status. What is the rationale for orienting the patient to time, place, date, and events?
- A. Shows improved cognitive functioning
- B. Provides reality orientation to patient
- C. Permits evaluation of effectiveness of treatment
- D. Let the patient identify the time, place, date, and events correctly
Correct Answer: B
Rationale: The correct answer is B: Provides reality orientation to patient. Orienting the patient to time, place, date, and events helps them stay connected to reality and improves their awareness of their surroundings. This is crucial in assessing their cognitive functioning and ensuring they are grounded in the present moment. By providing reality orientation, healthcare providers can better understand the patient's current mental state and address any potential confusion or disorientation. This approach aids in establishing a therapeutic environment and enhances the patient's overall well-being. Choices A, C, and D do not capture the essence of reality orientation and its significance in maintaining the patient's mental clarity and connection to the present moment.
Which of the following statements is INCORRECT of collaboration in a health care settings?
- A. Trust and respect are core values of a collaborative organization. -
- B. A shared vision is essential for collaboration in any health care operations.
- C. Successful conflict resolution can help collaborative teams overcome differences.
- D. Inter professional collaboration & multidisciplinary collaboration can be used interchangeably.
Correct Answer: D
Rationale: The correct answer is D because interprofessional collaboration and multidisciplinary collaboration are not interchangeable terms. Interprofessional collaboration involves professionals from different disciplines working together to provide comprehensive care, while multidisciplinary collaboration involves professionals from various disciplines working alongside each other but not necessarily working together in a coordinated manner. This distinction is crucial in healthcare settings to ensure effective teamwork and patient-centered care.
A: Trust and respect are core values of a collaborative organization - This statement is correct because trust and respect are essential for effective collaboration in healthcare settings.
B: A shared vision is essential for collaboration in any health care operations - This statement is correct as a shared vision helps align team members towards common goals.
C: Successful conflict resolution can help collaborative teams overcome differences - This statement is correct as resolving conflicts constructively can strengthen team dynamics and improve collaboration.
A patient presents with acute onset of shoulder pain and limited range of motion after a fall onto an outstretched hand. Physical examination reveals tenderness over the greater tuberosity of the humerus and pain with passive abduction and external rotation of the shoulder. Which of the following conditions is most likely?
- A. Rotator cuff tear
- B. Glenohumeral dislocation
- C. Acromioclavicular joint separation
- D. Proximal humerus fracture
Correct Answer: A
Rationale: The correct answer is A: Rotator cuff tear. The presentation of acute shoulder pain and limited range of motion after a fall onto an outstretched hand, along with tenderness over the greater tuberosity and pain with passive abduction and external rotation, is classic for a rotator cuff tear. The mechanism of injury and physical exam findings are consistent with this condition.
B: Glenohumeral dislocation typically presents with a visibly deformed shoulder and loss of normal shoulder contour.
C: Acromioclavicular joint separation would present with tenderness over the AC joint rather than the greater tuberosity, and typically involves a history of direct trauma to the shoulder.
D: Proximal humerus fracture would present with more diffuse shoulder pain and swelling, and not specific tenderness over the greater tuberosity.
