Nursing Elites

1. A female client with acute respiratory distress syndrome (ARDS) is sedated and on a ventilator with 50% FIO2. What assessment finding warrants immediate intervention?

• A. Assess the client’s lung sounds bilaterally.
• B. Diminished left lower lobe sounds.
• C. Monitor ventilator settings for changes in oxygen levels.
• D. Increased sputum production and shortness of breath.

Correct answer: B

Rationale: Diminished breath sounds in a sedated client with ARDS and on a ventilator indicate collapsed alveoli, which requires immediate intervention, such as chest tube insertion, to prevent further lung damage. Assessing bilateral lung sounds (Choice A) is important but not as urgent as identifying diminished sounds in a specific location. Monitoring ventilator settings (Choice C) is essential but does not directly address the immediate need for intervention due to diminished breath sounds. Increased sputum production and shortness of breath (Choice D) may indicate other issues but are not specific to the urgency of addressing diminished breath sounds in ARDS.

2. The nurse is caring for a client with chronic heart failure who is receiving digoxin therapy. The nurse reviews the client's lab results and notes that the serum potassium level is 3.0 mEq/L. What action should the nurse take next?

• A. Administer a potassium supplement
• B. Notify the healthcare provider
• C. Hold the next dose of digoxin
• D. Increase dietary potassium intake

Correct answer: C

Rationale: In clients receiving digoxin therapy, low potassium levels can increase the risk of digoxin toxicity. Therefore, when the nurse notes a serum potassium level of 3.0 mEq/L, it is crucial to hold the next dose of digoxin. Notifying the healthcare provider is essential to ensure appropriate interventions, such as potassium supplementation, can be implemented. Administering a potassium supplement without healthcare provider guidance may lead to rapid potassium level changes and potential adverse effects. Increasing dietary potassium intake alone may not promptly address the low serum potassium level in this acute situation.

3. The healthcare provider prescribes an IV infusion of isoproterenol in D5W at 300 mcg/hour. How many ml/hour should the nurse set the pump to?

• A. 100 ml/hour
• B. 75 ml/hour
• C. 60 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct infusion rate, convert 300 mcg/hour to mg/hour (300 mcg = 0.3 mg). Since the IV solution is 1 mg in 250 ml, the rate is calculated as 0.3 mg/hour = 75 ml/hour. Therefore, the nurse should set the pump to 75 ml/hour. Choice A (100 ml/hour) is incorrect as it does not reflect the accurate calculation. Choice C (60 ml/hour) is incorrect as it is lower than the correct rate. Choice D (125 ml/hour) is incorrect as it is higher than the correct rate.

4. A client with hyperparathyroidism is preparing for surgery. Which preoperative lab finding is most important to report?

• A. Elevated serum calcium.
• B. Decreased serum albumin.
• C. Elevated serum potassium.
• D. Elevated serum magnesium.

Correct answer: A

Rationale: The correct answer is A: Elevated serum calcium. In hyperparathyroidism, elevated calcium levels can lead to complications such as kidney stones, bone pain, and fractures. During surgery, high calcium levels can affect neuromuscular function, cardiac function, and blood clotting. Therefore, it is crucial to report elevated serum calcium levels preoperatively to prevent potential surgical complications. Choices B, C, and D are not directly associated with hyperparathyroidism and are less likely to impact the surgical outcome in this scenario.

5. The nurse is evaluating the laboratory reports of a client with hypothyroidism. The nurse would expect which of the following laboratory values?

• A. Increased TSH
• B. Increased thyroxine (T4)
• C. Decreased TSH
• D. Decreased T3

Correct answer: A

Rationale: The correct answer is A: Increased TSH. In hypothyroidism, the thyroid gland is underactive, leading to low levels of thyroid hormones. As a compensatory mechanism, the pituitary gland releases more thyroid-stimulating hormone (TSH) to try to stimulate the thyroid gland to produce more hormones. Therefore, increased TSH levels are expected in hypothyroidism. Choice B is incorrect because in hypothyroidism, thyroxine (T4) levels are usually decreased, not increased. Choice C is incorrect as hypothyroidism is characterized by increased TSH levels, not decreased. Choice D is also incorrect because in hypothyroidism, T3 levels may be decreased, but TSH is a more sensitive indicator for diagnosis.
