Nursing Elites

1. Which of the following body processes is not dependent upon the presence of calcium in the body fluids?

• A. blood clotting
• B. transport of oxygen in the blood
• C. muscle contractions
• D. transmission of nerve impulses

Correct answer: B

Rationale: The transport of oxygen in the blood is carried out by hemoglobin, which does not require calcium; instead, calcium is essential for blood clotting, muscle contraction, and nerve transmission.

2. A nurse is reviewing blood glucose values for a client who is at risk for Diabetes Mellitus. Which of the following findings should the nurse report to the provider?

• A. 2-hour glucose tolerance test level 150 mg/dL
• B. Fasting blood glucose 70 mg/dL
• C. Glycosylated hemoglobin 5%
• D. Casual blood glucose 90 mg/dL

Correct answer: A

Rationale: The correct answer is A. A 2-hour glucose tolerance test level of 150 mg/dL is above the normal range and should be reported to the provider as it indicates impaired glucose tolerance. Choice B (Fasting blood glucose 70 mg/dL) is within the normal range. Choice C (Glycosylated hemoglobin 5%) is also within the normal range. Choice D (Casual blood glucose 90 mg/dL) is within the normal range and does not indicate impaired glucose tolerance.

3. Wernicke-Korsakoff syndrome is associated with which vitamin deficiency?

• A. Thiamine (B1)
• B. Riboflavin (B2)
• C. Niacin (B3)
• D. Pyridoxine (B6)

Correct answer: A

Rationale: Wernicke-Korsakoff syndrome is indeed associated with thiamine (vitamin B1) deficiency. This syndrome is commonly seen in individuals with chronic alcoholism due to poor diet and impaired thiamine absorption. Thiamine is essential for normal brain function and energy metabolism. Riboflavin (B2) deficiency can lead to symptoms like sore throat and swollen mucous membranes, not Wernicke-Korsakoff syndrome. Niacin (B3) deficiency causes pellagra, characterized by dermatitis, diarrhea, dementia, and death, but not Wernicke-Korsakoff syndrome. Pyridoxine (B6) deficiency can result in dermatitis, glossitis, and peripheral neuropathy, but it is not associated with Wernicke-Korsakoff syndrome.

4. Nancy blames God for her situation. She is easily provoked to tears and wants to be left alone, refusing to eat or talk to her family. A religious person before, she now refuses to pray or go to church stating that God has abandoned her. The nurse understands that Nancy is grieving for her self and is in the stage of:

• A. bargaining
• B. denial
• C. anger
• D. acceptance

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. Which nutrient is most important for the prevention of osteoporosis?

• A. Vitamin A
• B. Iron
• C. Calcium
• D. Protein

Correct answer: C

Rationale: Calcium is the most important nutrient for bone health and the prevention of osteoporosis. Calcium plays a crucial role in maintaining bone density and strength. Vitamin A is important for vision and immune function but is not directly related to bone health. Iron is essential for oxygen transport in the blood, while protein is important for muscle growth and repair. However, in the context of preventing osteoporosis, calcium is the key nutrient.
