1. 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.
2. The preferred route of administration of medication in the most acute care situations is which of the following routes?
- A. Intravenous C. Subcutaneous
- B. Epidural D. Intramuscular
- C.
- D.
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.
3. In the following ingredient list, which is the most abundant by weight? Ingredients: enriched flour, sugars, eggs, soy lecithin, artificial colors, natural flavors, milk.
- A. milk
- B. eggs
- C. sugar
- D. enriched flour
Correct answer: D
Rationale: The correct answer is 'enriched flour.' In ingredient lists, items are typically listed by weight in descending order. Therefore, the first ingredient, in this case, 'enriched flour,' is the most abundant by weight. Choice A, 'milk,' is not the most abundant as it appears last in the list. Choice B, 'eggs,' and choice C, 'sugar,' also rank lower in the list compared to 'enriched flour,' making them less abundant by weight.
4. What is the desirable resting systolic blood pressure for adults?
- A. <130 mmHg>
- B. <105 mmHg>
- C. <120 mmHg>
- D. <140 mmHg>
Correct answer: <120 mmHg>
Rationale: The desirable resting systolic blood pressure for adults is less than 120 mmHg. This blood pressure is associated with a lower risk of cardiovascular disease. Measurements higher than 120 mmHg (choices A and D) indicate elevated blood pressure, which can lead to hypertension and other health complications if not managed. A reading of less than 105 mmHg (choice B) could indicate low blood pressure, which also poses health risks such as dizziness and fainting.
5. Magnesium's major functions in the body would be least likely to include which of the following?
- A. allowing muscles to relax after contraction
- B. assisting the operation of hundreds of enzymes
- C. synthesis of protein in the soft tissues
- D. regulation of body temperature
Correct answer: D
Rationale: Magnesium plays a key role in muscle relaxation, enzyme operation, and protein synthesis, but it is not directly involved in regulating body temperature.
