1. 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.

2. What is the conversion of genetic information in RNA into a sequence of amino acids?

• A. translation
• B. transcription
• C.
• D.

Correct answer: A

Rationale: The correct answer is 'translation.' Translation is the process where the genetic information in messenger RNA (mRNA) is decoded to produce a specific sequence of amino acids, forming a protein. This process occurs at ribosomes within the cell. Option B, 'transcription,' is incorrect as transcription is the process of synthesizing mRNA from a DNA template. Options C and D are irrelevant as they are not related to the conversion of genetic information into amino acids.

3. Which organ produces and secretes bicarbonate ions and insulin?

• A. Stomach
• B. Pancreas
• C. Large intestine
• D. Small intestine

Correct answer: B

Rationale: The pancreas is the correct answer because it performs two vital functions: producing bicarbonate ions to neutralize stomach acid in the small intestine and secreting insulin to regulate blood glucose levels. The stomach is incorrect because its primary function is to break down and digest food, not produce bicarbonate ions or insulin. The large and small intestines are also incorrect because their primary functions are to absorb nutrients and water from food, rather than producing bicarbonate ions or insulin.

4. An appropriate nursing diagnosis for clients in the acute manic phase of bipolar disorder is:

• A. Risk for injury directed to self
• B. Risk for injury directed to others
• C. Impaired nutrition less than body requirements
• D. Ineffective individual coping

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

5. What are the manifestations of nephrotic syndrome?

• A. Dehydration
• B. Uremia
• C. Infection
• D. Low blood lipids

Correct answer: C

Rationale: Infection is a common manifestation of nephrotic syndrome. This is due to the loss of immunoglobulins in the urine, which weakens the body's immune defenses. Dehydration (Choice A) and uremia (Choice B) can be symptoms of kidney dysfunction but are not specific manifestations of nephrotic syndrome. Low blood lipids (Choice D) is incorrect as nephrotic syndrome typically results in high, not low, blood lipid levels due to the body's attempt to replace lost proteins.
