Nursing Elites

1. The nurse is teaching a group of women about osteoporosis and exercise. The nurse should emphasize the need for which type of regular activity?

• A. Weight-bearing exercise
• B. Aerobic exercise
• C. Low-impact exercises such as swimming
• D. Stretching and flexibility exercises

Correct answer: A

Rationale: The correct answer is A: Weight-bearing exercise. Weight-bearing exercise helps build and maintain bone density, which is critical in preventing osteoporosis. Activities like aerobic exercises, stretching, and low-impact exercises such as swimming are beneficial for overall fitness but do not directly contribute to improving bone strength, making them less effective in preventing osteoporosis.

2. 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.

3. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?

• A. Metabolic alkalosis
• B. Respiratory alkalosis
• C. Respiratory acidosis
• D. Metabolic acidosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.

4. A client was just taken off the ventilator after surgery and has a nasogastric tube draining bile-colored liquids. Which nursing measure will provide the most comfort to the client?

• A. Allow the client to melt ice chips in the mouth
• B. Provide mints to freshen the breath
• C. Perform frequent oral care with a tooth sponge
• D. Swab the mouth with glycerin swabs

Correct answer: C

Rationale: Performing frequent oral care with a tooth sponge is the most appropriate nursing measure in this scenario. This helps maintain comfort and prevent dryness in clients with nasogastric tubes. Allowing the client to melt ice chips in the mouth may not address oral care needs effectively. Providing mints to freshen the breath is not the priority when the client needs oral care. Swabbing the mouth with glycerin swabs may not be as effective as performing thorough oral care with a tooth sponge.

5. A client with diabetes mellitus is experiencing diabetic ketoacidosis (DKA). What laboratory result should the nurse monitor closely?

• A. White blood cell count of 15,000.
• B. Blood glucose level of 320 mg/dL.
• C. Sodium level of 145 mEq/L.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: B

Rationale: A blood glucose level of 320 mg/dL indicates the need for insulin to manage diabetic ketoacidosis.
