Nursing Elites

1. How is the stomach protected from damage by gastric acid?

• A. enzymes present in the stomach
• B. a protective bacteria in the stomach
• C. bicarbonate present in the stomach
• D. the mucus lining of the stomach

Correct answer: D

Rationale: The correct answer is D. The stomach is protected from gastric acid by a thick mucus lining that acts as a physical barrier, preventing the acid from eroding the stomach walls. Enzymes in the stomach help with digestion but do not play a significant role in protecting the stomach from acid damage, so choice A is incorrect. While some bacteria in the stomach can be beneficial, they do not primarily protect the stomach from gastric acid, making choice B incorrect. Bicarbonate, a base, can neutralize acid, but it is not the primary defense mechanism against gastric acid in the stomach, so choice C is also incorrect.

2. 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.

3. A nurse is caring for an older adult client who reports difficulty chewing due to ill-fitting dentures. Which of the following foods should the nurse recommend for the client?

• A. Dried fruit
• B. Roast beef
• C. Tuna fish
• D. Apple slices

Correct answer: C

Rationale: The correct answer is C: Tuna fish. Tuna fish is a soft and easy-to-chew option, suitable for clients with ill-fitting dentures. Dried fruit (choice A) can be tough to chew and may stick to the dentures, causing discomfort. Roast beef (choice B) requires significant chewing effort and may not be suitable for someone with difficulty chewing. Apple slices (choice D) are crunchy and hard, which can be challenging for individuals with ill-fitting dentures.

4. Which team member works with the client to evaluate the need for special feeding devices and then teaches the client how to use the device?

• A. dietitian
• B. speech-language pathologist
• C. dietetic technician
• D. occupational therapist

Correct answer: D

Rationale: An occupational therapist is the team member who works with the client to evaluate the need for special feeding devices and teaches the client how to use them. Occupational therapists specialize in helping individuals with physical or cognitive impairments to perform daily activities. In this scenario, the need for special feeding devices may be due to impaired motor function or disability, making the occupational therapist the correct choice. The other options, dietitian, speech-language pathologist, and dietetic technician, do not typically specialize in evaluating the need for feeding devices or teaching clients how to use them.

5. A healthcare professional is reviewing the laboratory findings of a client who has heart failure. Which of the following findings indicates that the client is experiencing fluid volume excess?

• A. BUN 8 mg/dL
• B. Hgb 15 g/dL
• C. Creatinine 0.8 mg/dL
• D. Sodium 140 mEq/L

Correct answer: A

Rationale: A BUN level of 8 mg/dL indicates fluid volume excess in a client with heart failure. BUN (Blood Urea Nitrogen) levels can be low in fluid overload due to hemodilution, a common occurrence in heart failure. High levels of BUN usually indicate dehydration or impaired renal function, which are not the case in fluid volume excess. Choices B, C, and D are within normal ranges and do not specifically indicate fluid volume excess.
