Nursing Elites

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. The term associated with loss of taste is:

• A. Xerostomia
• B. Hypogeusia
• C. Dysphagia
• D. Anosmia

Correct answer: B

Rationale: The correct answer is B, 'Hypogeusia.' Hypogeusia refers to a diminished sense of taste, which can impact nutritional intake, especially in older adults. Xerostomia (choice A) is dry mouth, Dysphagia (choice C) is difficulty swallowing, and Anosmia (choice D) is the loss of the sense of smell. These conditions are different from loss of taste, making them incorrect choices for this question.

3. When performing endotracheal suctioning, the nurse applies suctioning while withdrawing and gently rotating the catheter 360 degrees for which of the following time periods?

• A. 10-15 seconds
• B. 30-35 seconds
• C. 20-25 seconds
• D. 0-5 seconds

Correct answer: D

Rationale: During endotracheal suctioning, the nurse should apply suctioning while withdrawing and gently rotating the catheter 360 degrees for a short period of 0-5 seconds. This brief duration helps minimize the risk of hypoxia and trauma to the airway. Choices A, B, and C suggest longer time periods for suctioning, which can increase the risk of complications such as hypoxia, mucosal damage, and the removal of excess amounts of airway secretions.

4. What physiological role does phosphorus play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction, and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: D

Rationale: The correct answer is D. Phosphorus plays a crucial role in ATP energy release, the metabolism of fats, carbohydrates, and proteins, and regulation of acid-base balance. Choices A, B, and C are incorrect. Phosphorus is not directly involved in blood clotting, transmission of nerve impulses, muscle contraction, or calcium homeostasis. It also has known metabolic functions and is not associated with caries prevention.

5. In preparation for ECT, the nurse knows that it is almost similar to that of:

• A. ECG
• B. General Anesthesia
• C. EEG
• D. MRI

Correct answer: B

Rationale: The correct answer is B: General Anesthesia. In preparation for ECT (Electroconvulsive Therapy), the nurse should be aware that it is almost similar to the process of administering general anesthesia. This similarity is crucial as it involves sedation and muscle relaxation to ensure safety during the procedure. Choice A (ECG) is incorrect because ECT and ECG (Electrocardiogram) serve different purposes and involve distinct procedures. Choice C (EEG) is incorrect as EEG (Electroencephalogram) measures brain activity and is not directly related to ECT. Choice D (MRI) is also incorrect as MRI (Magnetic Resonance Imaging) is a diagnostic imaging procedure that does not involve sedation or muscle relaxation like ECT and general anesthesia.
