1. Scurvy is caused by a deficiency of ascorbic acid (Vitamin C) because ascorbic acid is required for collagen synthesis. Is this statement true or false?

• A. TRUE
• B. FALSE
• C. Not applicable
• D. Not applicable

Correct answer: A

Rationale: The statement is accurate. Scurvy is indeed caused by a deficiency in ascorbic acid, which is another name for Vitamin C. This vitamin plays a crucial role in the synthesis of collagen, a protein that helps in the formation and strength of skin, blood vessels, tissues, and bones. When the body lacks Vitamin C, it cannot produce enough collagen, leading to symptoms associated with scurvy such as bleeding gums and weakened immunity. The choice 'False' is incorrect because it contradicts the proven medical and scientific understanding of the causes of scurvy. Choices 'C' and 'D' are marked as 'Not applicable' because the question only requires a true or false answer.

2. You are an ostomy nurse and you know that colostomy is defined as:

• A. It is an incision into the colon to create an artificial opening to the exterior of the abdomen
• B. It is end to end anastomosis of the gastric stump to the duodenum
• C. It is end to end anastomosis of the gastric stump to the jejunum
• D. It is an incision into the ileum to create an artificial opening to the exterior of the abdomen

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. Which food provides a 1-ounce serving of grains for a preschool child?

• A. 1 cup of ready-to-eat cereal flakes
• B. 1⁄2 slice of whole wheat bread
• C. 1⁄2 of a 6-inch flour tortilla
• D. 1 cup of cooked rice

Correct answer: A

Rationale: The correct answer is A: 1 cup of ready-to-eat cereal flakes. For a preschool child, 1 cup of ready-to-eat cereal flakes provides a 1-ounce serving of grains, meeting the requirement. Choice B, 1⁄2 slice of whole wheat bread, is not the correct answer as it does not constitute a 1-ounce serving of grains. Similarly, choice C, 1⁄2 of a 6-inch flour tortilla, does not offer a 1-ounce serving of grains. Choice D, 1 cup of cooked rice, also does not provide a 1-ounce serving of grains for a preschool child, making it an incorrect choice.

4. After cleaning the abrasions and applying antiseptic, the nurse applies a cold compress to the swollen ankle as ordered by the physician. This statement shows that the nurse has a correct understanding of the use of a cold compress:

• A. Cold compress reduces blood viscosity in the affected area
• B. It is safer to apply than a hot compress
• C. Cold compress prevents edema and reduces pain
• D. It eliminates toxic waste products due to vasodilation

Correct answer: C

Rationale: The correct understanding of using a cold compress includes knowing that it helps prevent edema and reduces pain. Cold application constricts blood vessels, reducing blood flow to the area, which helps decrease swelling and pain. Choices A, B, and D are incorrect because cold compresses do not directly affect blood viscosity, safety compared to hot compresses, or eliminate toxic waste products due to vasodilation. It is essential for nurses to have a clear understanding of the rationale behind interventions to provide effective patient care.

5. The recommended daily fluid intake of patients maintained using hemodialysis is:

• A. 150 mL plus the volume of urinary output
• B. 500 mL plus the volume of urinary output
• C. 1000 mL plus the volume of urinary output
• D. 1500 mL plus the volume of urinary output

Correct answer: C

Rationale: The correct answer is C: 1000 mL plus the volume of urinary output. Fluid intake is typically restricted in hemodialysis patients to prevent fluid overload. The recommended daily fluid intake for these patients is 1000 mL plus any urinary output. Choice A (150 mL plus the volume of urinary output) is too low and would not provide enough fluid for these patients. Choice B (500 mL plus the volume of urinary output) is also insufficient. Choice D (1500 mL plus the volume of urinary output) is too high and may lead to fluid overload in hemodialysis patients.
