Nursing Elites

1. The nurse is reviewing laboratory results on a client with acute renal failure. Which one of the following should be reported immediately?

• A. Blood urea nitrogen 50 mg/dl
• B. Hemoglobin of 10.3 g/dl
• C. Venous blood pH 7.30
• D. Serum potassium 6 mEq/L

Correct answer: D

Rationale: A serum potassium level of 6 mEq/L indicates hyperkalemia, which can be life-threatening and requires immediate intervention. Hyperkalemia can lead to dangerous cardiac arrhythmias and must be addressed promptly. The other options are not as urgent. A blood urea nitrogen level of 50 mg/dl may indicate kidney dysfunction but does not require immediate intervention. Hemoglobin of 10.3 g/dl may suggest anemia, which needs management but is not an immediate threat. A venous blood pH of 7.30 may indicate acidosis, which is concerning but not as acutely dangerous as hyperkalemia.

2. A nurse is reinforcing teaching about reliable sources of Vitamin B12 with a client who is pregnant. Which of the following foods should the nurse recommend in the teaching?

• A. Figs
• B. Broccoli
• C. Stewed tomatoes
• D. Skim milk

Correct answer: D

Rationale: Skim milk is a reliable source of Vitamin B12, which is essential for the health of both the mother and the developing fetus. While figs, broccoli, and stewed tomatoes are nutritious foods, they are not significant sources of Vitamin B12. Figs are a good source of fiber and other vitamins, broccoli is rich in Vitamin C and K, and stewed tomatoes are high in Vitamin C and antioxidants, but they do not contain Vitamin B12 as much as skim milk does.

3. A client is scheduled for a colonoscopy. Which of these instructions should the nurse provide?

• A. You should avoid eating or drinking anything after midnight the day before the test.
• B. You may have a light breakfast the morning of the test.
• C. You will need to drink a bowel preparation solution the day before the test.
• D. You will need to avoid taking any medications the day before the test.

Correct answer: C

Rationale: The correct answer is C: 'You will need to drink a bowel preparation solution the day before the test.' Before a colonoscopy, it is essential to cleanse the colon thoroughly by drinking a bowel preparation solution. This helps to ensure that the colon is clear for the procedure, allowing for better visualization and examination of the colon. Choices A, B, and D are incorrect because avoiding eating or drinking after midnight, having a light breakfast, and avoiding medications are not specific instructions related to the colonoscopy preparation process.

4. After surgery, a client has been taken off the ventilator and has a nasogastric tube draining bile-colored liquids. Which nursing measure will provide the most comfort to the client?

• A. Allow the client to melt ice chips in the mouth
• B. Provide mints to freshen the breath
• C. Perform frequent oral care with a tooth sponge
• D. Swab the mouth with glycerin swabs

Correct answer: C

Rationale: Performing frequent oral care with a tooth sponge is the most appropriate nursing measure in this situation. It helps maintain oral hygiene, prevent dryness, and provide comfort for a client with an NG tube. Allowing the client to melt ice chips may not be suitable immediately post-surgery due to potential risks. Providing mints or swabbing the mouth with glycerin swabs may not address the need for proper oral care and hygiene, which is essential for a client with an NG tube.

5. A nurse is assisting with the development of an education program for a community group about intake of vitamins and minerals in the diet. Which of the following foods should the nurse recommend as the best source of vitamin C?

• A. ½ cup green pepper
• B. 1 medium orange
• C. ½ cup cabbage
• D. 1 medium tomato

Correct answer: B

Rationale: The correct answer is B: 1 medium orange. Oranges are well-known for being rich in vitamin C, an essential nutrient for immune function and skin health. While choices A, C, and D also contain some vitamin C, the medium orange provides a higher amount of this vitamin compared to a ½ cup of green pepper, ½ cup of cabbage, or a medium tomato.
