1. Which is most likely to initiate periodontal disease?
- A. Nutrient deficiencies
- B. Nutrient excesses
- C. Nutrient imbalances
- D. Plaque biofilm
Correct answer: D
Rationale: Plaque biofilm is the primary initiator of periodontal disease, as it harbors bacteria that can lead to inflammation and destruction of the periodontal tissues.
2. A healthcare professional is reviewing the lab results of a client who has bulimia nervosa. The professional should notify the provider of which of the following results?
- A. White Blood Cells 5,200/mm³
- B. Hemoglobin 14 g/dL
- C. Magnesium 1.6 mg/dL
- D. Potassium 3.2 mEq/L
Correct answer: D
Rationale: A potassium level of 3.2 mEq/L is below normal and requires provider notification, especially in clients with bulimia nervosa who are at risk of electrolyte imbalances. Low potassium levels can lead to serious complications like cardiac arrhythmias. The other options are within or close to the normal range and would not be a priority for notification.
3. What is the purpose of a chest tube after a lobectomy procedure, as understood by the nurse?
- A. Prevent mediastinal shift
- B. Promote chest expansion of the remaining lung
- C. Drain fluids and blood accumulated post-operatively
- D. Remove the air in the lungs to promote lung expansion
Correct answer: C
Rationale: After a lobectomy, a chest tube is typically inserted to drain fluids and blood that may have accumulated post-operatively. This tube helps to prevent complications, such as infections or pneumonia, and aids in patient recovery. While a chest tube may aid in preventing a mediastinal shift (Choice A), promoting chest expansion of the remaining lung (Choice B), and removing air in the lungs to promote lung expansion (Choice D), these are not the primary reasons for its use after a lobectomy. Therefore, Choices A, B, and D are incorrect.
4. A nurse is planning to teach a client about a low-potassium diet. Which of the following foods should the nurse instruct the client to avoid?
- A. Butter
- B. Poultry
- C. Yogurt
- D. Orange juice
Correct answer: D
Rationale: Orange juice is high in potassium and should be avoided in a low-potassium diet. Butter, poultry, and yogurt are low-potassium food choices and can be included in a low-potassium diet. Poultry is a good source of lean protein, yogurt is a good source of calcium and protein, and butter is low in potassium. Therefore, the nurse should instruct the client to avoid orange juice as it is high in potassium, which is not suitable for a low-potassium diet.
5. A healthcare provider is evaluating a client who reports paresthesia of the hands and feet. The provider should identify this manifestation as an indication of which of the following dietary deficiencies?
- A. Iron
- B. Riboflavin
- C. Vitamin C
- D. Vitamin B12
Correct answer: D
Rationale: Correct! Vitamin B12 deficiency can lead to neurological symptoms, including paresthesia (tingling or numbness) of the hands and feet, due to its role in nerve health. Iron deficiency is more commonly associated with anemia symptoms like fatigue and pallor. Riboflavin deficiency can cause mouth and skin changes. Vitamin C deficiency is linked to scurvy symptoms like bleeding gums and easy bruising.
