Nursing Elites

1. Laboratory findings indicate that a client’s serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Administer potassium supplements orally.
• B. Increase the client's dietary potassium intake.
• C. Inform the healthcare provider of the need for potassium replacement.
• D. Monitor the client's ECG continuously.

Correct answer: C

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. In this situation, it is essential for the nurse to inform the healthcare provider promptly about the need for potassium replacement. Administering potassium supplements orally or increasing dietary potassium intake is not appropriate in cases of critically low potassium levels as immediate and precise replacement is necessary. Monitoring the client's ECG continuously is important in severe cases of hypokalemia, but the priority action should be to inform the healthcare provider for further management and treatment.

2. What is the main characteristic of cystic fibrosis?

• A. Multiple upper respiratory infections
• B. An underproduction of exocrine glands
• C. Excessive, thick mucus
• D. An overproduction of thin mucus

Correct answer: C

Rationale: The main characteristic of cystic fibrosis is the production of excessive, thick mucus. This thick mucus leads to blockages in the airways, digestive system, and other organs. Choice A is incorrect because while individuals with cystic fibrosis are more prone to respiratory infections, the main characteristic is the mucus production. Choice B is incorrect as cystic fibrosis is characterized by the overproduction, not underproduction, of exocrine glands. Choice D is also incorrect as the mucus produced in cystic fibrosis is thick, not thin.

3. Which instruction should the nurse provide a client who was recently diagnosed with Raynaud's disease?

• A. Avoid cold temperatures completely.
• B. Take medications only during flare-ups.
• C. Wear gloves when removing packages from the freezer.
• D. Limit physical activity to avoid stress.

Correct answer: C

Rationale: The correct instruction for a client with Raynaud's disease is to wear gloves when handling cold items to prevent vasospasm. Raynaud's disease is characterized by vasospasm in response to cold or stress, leading to reduced blood flow to extremities. Wearing gloves when removing packages from the freezer helps minimize exposure to cold temperatures and can prevent triggering vasospasms. Choices A, B, and D are incorrect. Avoiding cold temperatures completely is impractical and may not always be possible. Taking medications only during flare-ups does not address prevention strategies, and limiting physical activity to avoid stress is not a primary intervention for Raynaud's disease.

4. A client who has a history of hyperthyroidism was initially admitted with lethargy and confusion. Which additional finding warrants the most immediate action by the nurse?

• A. Facial puffiness and periorbital edema
• B. Hematocrit of 30%
• C. Cold and dry skin
• D. Further decline in LOC

Correct answer: D

Rationale: A further decline in LOC can indicate severe complications and requires immediate attention. This change may signify worsening neurological status, which could lead to life-threatening consequences if not addressed promptly. Choices A, B, and C may also be concerning in a client with a history of hyperthyroidism, but a further decline in LOC takes priority due to its potential for rapid deterioration and the need for urgent intervention.

5. A client with Addison's disease started taking hydrocortisone in a divided daily dose last week. It is most important for the nurse to monitor which serum laboratory value?

• A. Osmolarity
• B. Glucose
• C. Albumin
• D. Platelets

Correct answer: B

Rationale: The correct answer is B: Glucose. Hydrocortisone can lead to increased blood glucose levels, so monitoring glucose is crucial to assess for hyperglycemia, a common side effect of corticosteroid therapy. Monitoring osmolarity (choice A) is not typically indicated in this scenario. Albumin (choice C) and platelets (choice D) are not directly affected by hydrocortisone therapy and are not the primary focus of monitoring in this case.
