Nursing Elites

1. After bronchoscopy, the nurse's priority is to check which of the following before feeding?

• A. Gag reflex
• B. Wearing off of anesthesia
• C. Swallowing reflex
• D. Peristalsis

Correct answer: A

Rationale: After a bronchoscopy procedure, the nurse's priority is to check the patient's gag reflex before allowing them to eat to prevent aspiration. The gag reflex helps protect the airway by triggering a cough or gag response if something touches the back of the throat. This is crucial to ensure that the patient can protect their airway and prevent food or fluids from entering the lungs, especially when the throat may be sensitive or compromised post-bronchoscopy. Checking for the wearing off of anesthesia, swallowing reflex, or peristalsis are important assessments but not the immediate priority before feeding in this context.

2. Which enzyme initiates protein digestion in the stomach?

• A. Pepsin
• B. Salivary Amylase
• C. CCK
• D. Secretin

Correct answer: A

Rationale: Pepsin is the enzyme that initiates protein digestion in the stomach. It breaks down proteins into smaller peptides, aiding in their further digestion and absorption in the intestines. Salivary Amylase (Choice B) functions in breaking down dietary carbohydrates in the mouth, not proteins. CCK (Choice C) and Secretin (Choice D) are hormones involved in the digestion of fats and carbohydrates, not proteins. Therefore, Choices B, C, and D are incorrect in the context of protein digestion in the stomach.

3. Which nutrient is most important for maintaining fluid balance in the body?

• A. Protein
• B. Sodium
• C. Calcium
• D. Vitamin C

Correct answer: B

Rationale: Sodium plays a key role in maintaining fluid balance and regulating blood pressure.

4. Are the following statements both true: 'Most excess energy intake, whether from protein, carbohydrate, alcohol, or fat, is stored in the liver' and 'Fat is a good source of energy, but the preferred fuel is protein'?

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

Correct answer: B

Rationale: Both of the given statements are false. The first statement is inaccurate because the primary location for excess energy storage is not the liver, but rather adipose tissue where it is stored as fat. While the liver does have a role in energy storage and metabolism, it is not the main storage site for excess intake. The second statement is also incorrect. Although fat and protein can be used as sources of energy, the body's preferred source of energy is carbohydrates. They break down more efficiently and are easier for the body to use. The body prefers to conserve protein for other essential functions, such as tissue repair and the production of enzymes. Therefore, protein is not the preferred fuel source.

5. A client is being prepared for placement of a catheter for total parenteral nutrition. Which of the following access sites should be planned for catheter insertion?

• A. Left antecubital vein
• B. Right subclavian vein
• C. Right femoral artery
• D. Left arm radial artery

Correct answer: B

Rationale: The correct answer is the Right subclavian vein. When preparing a client for placement of a catheter for total parenteral nutrition, the preferred access site for catheter insertion is the subclavian vein due to its large size, central location, and lower risk of infection compared to peripheral veins. The other options provided (Left antecubital vein, Right femoral artery, and Left arm radial artery) are not suitable access sites for central venous catheter insertion for total parenteral nutrition.
