1. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?

• A. The body can produce sufficient amounts of vitamin D from sunlight.
• B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
• C. Sunscreen blocks the formation of vitamin D3.
• D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.

Correct answer: C

Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.

2. Which vitamin is crucial for collagen synthesis and wound healing?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin E
• D. Vitamin K

Correct answer: A

Rationale: The correct answer is Vitamin C. Vitamin C is crucial for collagen synthesis, a process important for wound healing. Collagen is a key protein that helps in wound repair and tissue strength. Vitamin D is primarily known for its role in calcium absorption and bone health, not directly related to collagen synthesis. Vitamin E is an antioxidant that helps protect cells from damage but is not directly involved in collagen synthesis. Vitamin K is essential for blood clotting but does not play a major role in collagen synthesis for wound healing.

3. When observing a return demonstration of a colostomy irrigation, you know that more teaching is required if pt:

• A. Lubricates the tip of the catheter prior to inserting into the stoma
• B. Hangs the irrigating bag on the bathroom door cloth hook during fluid insertion
• C. Discontinues the insertion of fluid after only 500 ml of fluid has been instilled
• D. Clamps of the flow of fluid when felling uncomfortable

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. Nurse DMLM is correct in identifying the correct sequence of events during abdominal assessment if she identifies which of the following?

• A. Inspection, Auscultation, Percussion, Palpation
• B. Inspection, Percussion, Palpation, Auscultation
• C. Inspection, Palpation, Percussion, Auscultation
• D. Inspection, Auscultation, Palpation, Percussion

Correct answer: D

Rationale: The correct sequence for abdominal assessment is Inspection, Auscultation, Percussion, Palpation. Start with Inspection to observe any visible abnormalities, followed by Auscultation to listen for bowel sounds, then Percussion to assess the density of underlying structures, and finally Palpation to feel for any tenderness or masses. Choices A, B, and C have the incorrect sequence of assessment techniques.

5. Each statement accurately describes the physical effects of food on periodontal health, except one. Which is the exception?

• A. Supragingival plaque biofilm adhesion is influenced by frequent consumption of monosaccharides
• B. Supragingival plaque biofilm adhesion is influenced by frequent consumption of disaccharides
• C. Poor nutrition has an adverse effect on the periodontium
• D. Chewing soft, spongy foods stimulates salivary flow

Correct answer: D

Rationale: The correct answer is D. Chewing soft, spongy foods does not stimulate salivary flow; rather, firm, fibrous foods like fruits and vegetables do. Soft foods can stick to teeth, promoting plaque buildup. Choices A, B, and C are accurate: Supragingival plaque biofilm adhesion is influenced by both monosaccharides and disaccharides, while poor nutrition can indeed have adverse effects on the periodontium.
