1. What is the glomerular filtration rate for patients with stage 5 chronic kidney disease (CKD)?

• A. Less than 15 mL/min/1.73 m�
• B. Less than 30 mL/min/1.73 m�
• C. Less than 90 mL/min/1.73 m�
• D. Less than 125 mL/min/1.73 m�

Correct answer: A

Rationale: In patients with stage 5 chronic kidney disease (CKD), also known as end-stage renal disease, the kidney function is significantly compromised. This severe condition is characterized by a glomerular filtration rate (GFR) of less than 15 mL/min/1.73 m�, as correctly stated in choice A. Choices B, C, and D suggest higher GFR values, which are not indicative of stage 5 CKD. Specifically, a GFR of less than 30 mL/min/1.73 m� indicates stage 4 CKD, less than 90 mL/min/1.73 m� signifies stage 3 CKD, and a typical healthy individual usually has a GFR of around 125 mL/min/1.73 m�, which is far above the GFR for stage 5 CKD.

2. Worldwide, what is the most common nutrient deficiency?

• A. magnesium deficiency
• B. iron deficiency
• C. selenium deficiency
• D. zinc deficiency

Correct answer: B

Rationale: Iron deficiency is the most common nutrient deficiency globally. It leads to anemia and affects many populations, especially women and children. Magnesium, selenium, and zinc deficiencies are important, but they are not as prevalent as iron deficiency on a global scale.

3. The purpose of chest percussion and vibration is to loosen secretions in the lungs. The difference between the procedures is:

• A. Percussion uses only one hand, while vibration uses both hands
• B. Percussion delivers cushioned blows to the chest with cupped palms, while vibration gently shakes secretions loose
• C. In both percussion and vibration, the hands are not on top of each other, and hand action is not in tune with the client's breath
• D. Percussion slaps the chest to loosen secretions, while vibration shakes the secretions along with the inhalation

Correct answer: D

Rationale: Chest percussion involves the use of rhythmic tapping to dislodge mucus from the lungs, facilitating its movement toward the larger airways where it can be expelled. This technique is particularly important in conditions where mucus retention is a significant risk factor for infection. The key difference between chest percussion and vibration is that percussion involves slapping the chest to loosen secretions, while vibration involves shaking the secretions along with the inhalation, aiding in moving the loosened secretions upwards for easier removal. Choices A, B, and C do not accurately describe the main difference between chest percussion and vibration, making them incorrect.

4. What is the term for the act of performing beneficial services rather than harmful ones?

• A. Beneficence
• B. Disclosure
• C. Maleficence
• D. Justice

Correct answer: A

Rationale: The term for the act of performing beneficial services rather than harmful ones is 'Beneficence'. Beneficence refers to actions that enhance the well-being of others. In the healthcare context, beneficence ensures that health services are advantageous and beneficial to patients. 'Disclosure' (choice B) is the act of revealing information, not directly related to whether actions are beneficial or harmful. 'Maleficence' (choice C) is the opposite of beneficence, involving actions that can cause damage or harm. 'Justice' (choice D) denotes fairness and equality, important in various contexts but not specifically related to performing beneficial services.

5. Systemic disease often manifests in the oral cavity first. Disease within the oral cavity can cause systemic complications.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: A

Rationale: Both statements are true. Systemic diseases can often present with oral manifestations before other systemic signs appear. Additionally, oral diseases can have systemic implications by affecting a person's overall health, such as through inflammation or compromised nutrient intake. Choice B is incorrect because both statements are true, as supported by medical literature. Choice C is incorrect because the second statement is also true. Choice D is incorrect because the first statement is true.
