Nursing Elites

1. A client with chronic renal failure has a potassium level of 6.5 mEq/L. What is the nurse's priority action?

• A. Administer a potassium supplement.
• B. Notify the healthcare provider immediately.
• C. Administer calcium gluconate.
• D. Restrict the client's potassium intake.

Correct answer: B

Rationale: A potassium level of 6.5 mEq/L indicates hyperkalemia, which can lead to life-threatening arrhythmias. The correct priority action for the nurse is to notify the healthcare provider immediately. Hyperkalemia requires prompt intervention to lower potassium levels and prevent complications. Administering a potassium supplement (Choice A) would worsen the condition. Administering calcium gluconate (Choice C) is a treatment option but is not the nurse's priority action. Restricting the client's potassium intake (Choice D) may be necessary but is not the immediate priority when facing a critical potassium level.

2. A client with pneumonia is receiving oxygen therapy. What assessment finding requires immediate intervention?

• A. Increased oxygen saturation of 96%.
• B. Oxygen saturation of 89%.
• C. Respiratory rate of 20 breaths per minute.
• D. Decreased heart rate of 70 beats per minute.

Correct answer: B

Rationale: The correct answer is B. An oxygen saturation of 89% indicates hypoxemia, which is below the normal range (usually 95-100%). This finding requires immediate intervention as it signifies inadequate oxygenation. Options A, C, and D are within normal limits and do not indicate an urgent need for intervention. Option A indicates a good oxygen saturation level, option C denotes a normal respiratory rate, and option D suggests a normal heart rate. Therefore, these options do not require immediate intervention compared to the critically low oxygen saturation level of 89% in option B.

3. A client's chest tube insertion site has crepitus (crackling sensation) upon palpation. What is the nurse's next step?

• A. Apply a pressure dressing to the chest tube site.
• B. Administer an oral antihistamine.
• C. Assess the client for allergies to cleaning agents.
• D. Measure the area of swelling and crackling.

Correct answer: D

Rationale: The correct next step for the nurse is to measure the area of crepitus. Crepitus indicates subcutaneous emphysema, which is a serious condition requiring monitoring. Applying a pressure dressing (Choice A) could worsen the condition by trapping air under the skin. Administering an oral antihistamine (Choice B) is not indicated for crepitus. Assessing for allergies to cleaning agents (Choice C) is not the priority when dealing with crepitus and subcutaneous emphysema.

4. 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.

5. A client with hypothyroidism is prescribed levothyroxine. What assessment finding suggests the medication dosage is too high?

• A. Increased sensitivity to cold.
• B. Increased heart rate and palpitations.
• C. Improved energy levels.
• D. Improved tolerance to heat.

Correct answer: B

Rationale: The correct answer is B: Increased heart rate and palpitations. When a client with hypothyroidism is prescribed levothyroxine, these symptoms may indicate that the dosage is too high, causing the client to develop hyperthyroidism. Choices A, C, and D are incorrect. Increased sensitivity to cold is a symptom of hypothyroidism, improved energy levels are an expected outcome of levothyroxine therapy for hypothyroidism, and improved tolerance to heat is not a common sign of levothyroxine overdose.
