Nursing Elites

1. Medications that reduce stomach acidity can impair the absorption of _____.

• A. calcium
• B. iron
• C. vitamin D
• D. vitamin C

Correct answer: B

Rationale: Reduced stomach acidity impairs the absorption of iron, as an acidic environment is necessary for optimal iron absorption in the stomach. Choices A, C, and D are incorrect as medications that reduce stomach acidity typically do not significantly affect the absorption of calcium, vitamin D, or vitamin C.

2. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.

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

Correct answer: A

Rationale: Both statements are true. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.

3. What side effect is commonly associated with ECT?

• A. Transient loss of memory, confusion, and disorientation
• B. Nausea and vomiting
• C. Fractures
• D. Hypertension and increased heart rate

Correct answer: A

Rationale: The correct answer is A, as Electroconvulsive Therapy (ECT) is commonly associated with side effects such as transient loss of memory, confusion, and disorientation. While nausea and vomiting (Choice B) can occur, they are not as common as the memory-related side effects. Fractures (Choice C) are unlikely unless a mishap occurs during the procedure. Hypertension and increased heart rate (Choice D) might occur during the procedure due to the physiological stress of the treatment, but these are not the most commonly associated side effects. The rationale provided did not effectively explain this, so it's important to note that ECT is a procedure often used for severe depression and other mental illnesses, and understanding its side effects is crucial for patient safety and effective care.

4. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

5. Angie is a disoriented client who frequently falls from the bed. As her nurse, which of the following is the best nursing intervention to prevent future falls?

• A. Tell Angie not to get up from bed unassisted
• B. Put the call bell within her reach
• C. Put bedside commode at the bedside to prevent Angie from getting up
• D. Put the bed in the lowest position ever

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
