Nursing Elites

1. A client with severe COPD is receiving oxygen therapy at 2 liters per minute via nasal cannula. The client's oxygen saturation level drops to 88% during ambulation. What action should the nurse take first?

• A. Increase the oxygen flow rate to 4 liters per minute.
• B. Instruct the client to rest until the oxygen saturation improves.
• C. Discontinue ambulation and return the client to bed.
• D. Encourage the client to breathe more deeply.

Correct answer: C

Rationale: In this scenario, the client's oxygen saturation level dropping during ambulation indicates an inadequate oxygen supply. The first action the nurse should take is to discontinue ambulation and return the client to bed. This helps stabilize the oxygen level by reducing the oxygen demand placed on the client during physical activity. Increasing the oxygen flow rate without addressing the underlying issue of oxygen saturation dropping may not be effective. Instructing the client to rest is not enough to address the immediate need for stabilization of oxygen levels. Encouraging the client to breathe more deeply may not be sufficient to overcome the oxygen saturation drop caused by inadequate oxygen supply during ambulation.

2. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which laboratory value is most concerning?

• A. Serum glucose of 300 mg/dl
• B. Serum bicarbonate of 18 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Serum sodium of 135 mEq/L

Correct answer: C

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with DKA as it may indicate worsening hyperkalemia, requiring immediate intervention. Elevated serum potassium levels can lead to life-threatening cardiac arrhythmias. While elevated glucose and low bicarbonate are characteristic of DKA, hyperkalemia poses a higher immediate risk. Serum sodium within the normal range is not typically a primary concern in DKA.

3. A 66-year-old woman is retiring and will no longer have health insurance through her place of employment. Which agency should the client be referred to by the employee health nurse for health insurance needs?

• A. Woman, Infants, and Children program
• B. Medicaid
• C. Medicare
• D. Consolidated Omnibus Budget Reconciliation Act provision

Correct answer: C

Rationale: The correct answer is C: Medicare. Title XVII of the Social Security Act of 1965 created the Medicare Program to provide medical insurance for individuals who are 65 years or older, disabled, or have permanent kidney failure. Medicare is the appropriate agency to refer a 66-year-old woman who is retiring and losing her employment-based health insurance. Choice A, the Woman, Infants, and Children program, is not suitable for this scenario as it provides assistance for low-income pregnant women, breastfeeding women, and young children. Choice B, Medicaid, is a program that helps individuals with low income and resources cover medical costs, which may not be applicable to this woman's situation. Choice D, the Consolidated Omnibus Budget Reconciliation Act provision, known as COBRA, allows employees to continue their group health insurance coverage after leaving their job but may not be the best option for this woman in this case.

4. The nurse is caring for a client with a chest tube following a pneumothorax. Which finding requires immediate intervention?

• A. Oxygen saturation of 94%
• B. Crepitus around the insertion site
• C. Subcutaneous emphysema
• D. Drainage of 50 ml per hour

Correct answer: C

Rationale: Subcutaneous emphysema is the most critical finding requiring immediate intervention in a client with a chest tube following a pneumothorax. It may indicate a pneumothorax recurrence or air leak, which can lead to respiratory compromise. Oxygen saturation of 94% is slightly low but may not require immediate intervention. Crepitus around the insertion site can be a normal finding post-procedure. Drainage of 50 ml per hour is within the expected range for a chest tube output and does not indicate an immediate concern.

5. While auscultating a client's heart sounds, which description should the nurse use to document a swishing sound related to blood turbulence or valvular defect?

• A. S1 S2
• B. S1 S2 S3
• C. Murmur
• D. Pericardial friction rub

Correct answer: C

Rationale: The correct answer is 'C: Murmur.' A murmur is auscultated as a swishing sound associated with blood turbulence caused by the heart or a valvular defect. Choices 'A: S1 S2' and 'B: S1 S2 S3' refer to normal heart sounds, specifically the closure of heart valves. 'D: Pericardial friction rub' is a dry, rubbing or grating sound caused by inflammation of the pericardial sac and is not associated with blood flow or valvular issues.
