Nursing Elites

1. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?

• A. Short half-life
• B. High therapeutic index
• C. Highly protein-bound
• D. Low bioavailability

Correct answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

2. The nurse is assessing a client 2 hours postoperatively following an appendectomy. The nurse should intervene for which abnormal finding?

• A. Heart rate of 88 beats per minute
• B. Blood pressure of 100/60
• C. Oxygen saturation of 94%
• D. Respiratory rate of 16

Correct answer: C

Rationale: The correct answer is C. Oxygen saturation levels below 95% indicate hypoxia and require immediate intervention. A heart rate of 88 beats per minute, a blood pressure of 100/60, and a respiratory rate of 16 are within normal ranges and do not require immediate intervention. Oxygen saturation is a critical parameter reflecting the client's oxygenation status.

3. A client with diabetes mellitus is prescribed metformin. What teaching should the nurse include?

• A. Take the medication with meals to reduce gastrointestinal upset.
• B. Monitor renal function regularly due to the risk of lactic acidosis.
• C. Avoid alcohol consumption while taking this medication.
• D. Check blood glucose levels regularly to ensure proper management.

Correct answer: B

Rationale: The correct teaching for a client prescribed metformin includes monitoring renal function regularly due to the risk of lactic acidosis, especially in clients with impaired kidney function. While taking metformin with meals can reduce gastrointestinal upset, it is not the highest priority teaching point. Avoiding alcohol is generally recommended but not the most critical teaching point in this scenario. Checking blood glucose levels regularly is important for diabetes management but not specifically related to metformin use.

4. A client is diagnosed with chronic renal failure, and the nurse is teaching dietary modifications. What should be limited in this client's diet?

• A. Carbohydrates
• B. Fats
• C. Proteins
• D. Vitamins

Correct answer: C

Rationale: In chronic renal failure, proteins should be limited in the diet. When the kidneys are not functioning well, the buildup of protein byproducts can put additional stress on them. Limiting protein intake can help reduce the burden on the kidneys. Carbohydrates and fats do not need to be restricted in the same way as proteins. Vitamins are essential nutrients that should not be limited in the diet unless specified by a healthcare provider for a specific reason.

5. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving oxygen therapy. Which assessment finding indicates that the client's oxygenation is improving?

• A. Pulse oximetry reading of 94%
• B. Heart rate increases from 80 to 90 beats per minute
• C. Respiratory rate increases from 16 to 20 breaths per minute
• D. Client reports increased energy levels

Correct answer: A

Rationale: A pulse oximetry reading of 94% indicates adequate oxygenation. Monitoring oxygen saturation is the most objective way to assess the effectiveness of oxygen therapy. Choices B, C, and D do not directly reflect the client's oxygenation status. An increase in heart rate or respiratory rate may indicate increased work of breathing or stress on the body. The client reporting increased energy levels is subjective and may not directly correlate with improved oxygenation.
