Nursing Elites

1. Where does carbohydrate digestion begin?

• A. Mouth
• B. Esophagus
• C. Stomach
• D. Small intestine

Correct answer: A

Rationale: Carbohydrate digestion begins in the mouth. The enzyme amylase, found in saliva, starts the process by breaking down starches into sugars. The esophagus is a passageway for food to reach the stomach and does not participate in digestion. The stomach mainly digests proteins and is not the primary site for carbohydrate breakdown. While the small intestine does play a crucial role in digesting carbohydrates, it is not where the process initiates. Therefore, the correct answer is the mouth.

2. 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.

3. If a child has two or more pink signs, you would classify the child as having:

• A. No disease
• B. Mild form of disease
• C. Urgent Referral
• D. Very severe disease

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

4. Each statement is true of swallowing and processing food, except one. Which is the exception?

• A. The swallowing reflex moves a bolus into the esophagus
• B. A bolus is a mass of food
• C. The bolus is transported to the stomach by osmosis and gravity
• D. The bolus penetrates the diaphragm through the esophageal hiatus

Correct answer: C

Rationale: The correct answer is C. The bolus is not transported to the stomach by osmosis and gravity, but by peristalsis. Peristalsis is the involuntary constriction and relaxation of muscles to push the bolus through the digestive system. Choices A, B, and D are correct statements. A bolus is indeed a mass of food, the swallowing reflex does move the bolus into the esophagus, and the bolus does not penetrate the diaphragm through the esophageal hiatus; instead, it enters the stomach through the lower esophageal sphincter.

5. What is the digestive action of lipase?

• A. It breaks down carbohydrates
• B. It breaks down proteins
• C. It breaks down lipids
• D. It aids in fat digestion

Correct answer: C

Rationale: Lipase is an enzyme that specifically breaks down lipids (fats) during the process of digestion, converting them into fatty acids and glycerol. This is why option C is the correct answer. Although option D is partially correct, it's less specific than option C. Lipase does not break down carbohydrates or proteins, so options A and B are incorrect.
