Nursing Elites

1. While a client is on total parenteral nutrition, which of the following values should the nurse monitor closely?

• A. calcium
• B. magnesium
• C. glucose
• D. cholesterol

Correct answer: C

Rationale: Glucose should be monitored closely when a client is on total parenteral nutrition due to the high glucose concentration in the solutions. Monitoring glucose levels is crucial to prevent complications such as hyperglycemia or hypoglycemia. Calcium and magnesium are usually monitored to assess electrolyte imbalances, while cholesterol levels are not directly impacted by total parenteral nutrition. Therefore, choices A, B, and D are not the primary values that need close monitoring during total parenteral nutrition.

2. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

3. How often should the intravenous tubing on total parenteral nutrition solutions be changed?

• A. every 24 hours
• B. every 36 hours
• C. every 48 hours
• D. every 72 hours

Correct answer: A

Rationale: The correct answer is to change the intravenous tubing on total parenteral nutrition solutions every 24 hours. This frequency is necessary due to the high risk of bacterial growth associated with TPN solutions. Changing the tubing every 24 hours helps prevent contamination and bloodstream infections. Choices B, C, and D are incorrect because waiting longer intervals increases the risk of introducing harmful bacteria into the patient's system, leading to potentially severe complications.

4. When assessing a client with deep pitting edema, with the indentation remaining for a short time and visible leg swelling, how should a nurse document this finding?

• A. 1+ edema
• B. 2+ edema
• C. 3+ edema
• D. 4+ edema

Correct answer: C

Rationale: The correct answer is 3+ edema. When assessing for edema, the nurse presses thumbs against the ankle malleolus or the tibia. If the skin retains an indentation, it indicates pitting edema. The grading scale for pitting edema includes: 1+ for mild pitting with slight indentation and no perceptible leg swelling, 2+ for moderate pitting where the indentation subsides rapidly, 3+ for deep pitting with an indentation remaining briefly and visible leg swelling, and 4+ for very deep pitting with a long-lasting indentation and significant leg swelling. Choices A, B, and D do not accurately represent the severity of the edema described in the scenario.

5. Ms. Petty is having difficulty falling asleep. Which of the following measures promote sleep?

• A. exercising vigorously for 20 minutes each night beginning at 9:30 p.m.
• B. taking a cool shower and drinking a hot cup of tea
• C. watching TV nightly until midnight
• D. getting a back rub and drinking a glass of warm milk

Correct answer: D

Rationale: The correct answer is getting a back rub and drinking a glass of warm milk. These measures are relaxation techniques that can help promote sleep by calming the body and mind. Exercising vigorously right before bedtime, as mentioned in choice A, can increase arousal and make it harder to fall asleep. Choice B, taking a cool shower and drinking a hot cup of tea, involves temperature changes that might not be conducive to sleep. Watching TV until midnight, as in choice C, exposes the individual to blue light and mental stimulation, both of which can disrupt the natural sleep-wake cycle.
