Nursing Elites

1. 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.

2. 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.

3. A nurse is preparing a female client for a rectal examination. Into which position does the nurse assist the client?

• A. Supine
• B. Standing
• C. Lithotomy
• D. Left lateral

Correct answer: D

Rationale: For a rectal examination in a female client, the nurse should assist the client into the left lateral position. This position allows easier access to the rectal area, facilitating the examination. The lithotomy position is used for examining the genitalia and rectum in females, not solely for a rectal examination. The standing position is not appropriate for a rectal examination as it does not provide the necessary access. The supine position would hinder the effectiveness of a rectal examination as it does not optimize access to the rectal area.

4. A nurse assisting with data collection plans to assess tactile (vocal) fremitus. The nurse performs this by using which technique?

• A. Palpating for symmetric chest expansion
• B. Auscultating the breath sounds over the trachea and larynx
• C. Auscultating the breath sounds over the peripheral lung fields
• D. Palpating the thorax, comparing vibrations from side to side as the client repeats the word 'ninety-nine'

Correct answer: D

Rationale: To assess tactile (vocal) fremitus, the nurse palpates the thorax and compares vibrations from side to side as the client repeats the word 'ninety-nine.' This technique helps in evaluating the intensity and symmetry of vibrations felt. Palpating for symmetric chest expansion involves assessing the expansion of the chest during breathing by placing hands on the anterolateral wall. Auscultating the breath sounds over the trachea and larynx is done to assess bronchial breath sounds, while auscultating over the peripheral lung fields is used to assess vesicular breath sounds.

5. 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.
