Nursing Elites

1. The nurse needs to add a medication to a liter of 5% Dextrose in Water (D5W) that is already infusing into a client. At what location should the nurse inject the medication?

• A. Medication port
• B. IV drip chamber
• C. Y-site connector
• D. At the hub of the IV catheter

Correct answer: A

Rationale: The correct answer is the medication port. When adding medication to an already infusing IV solution, it should be done through the medication port to ensure direct delivery into the bloodstream without interrupting the primary IV line. Injecting the medication into the IV drip chamber, Y-site connector, or at the hub of the IV catheter can lead to dilution, inaccurate dosing, or potential blockages in the IV line, which can compromise the effectiveness of the medication and patient safety.

2. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding is most concerning to the nurse?

• A. Barrel-shaped chest
• B. Use of accessory muscles
• C. Oxygen saturation of 85%
• D. Respiratory rate of 28 breaths per minute

Correct answer: C

Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and indicates hypoxemia, requiring immediate intervention. In COPD, the body's ability to oxygenate adequately is already compromised, so a saturation of 85% is particularly concerning. A barrel-shaped chest and use of accessory muscles are common findings in COPD due to chronic air trapping and increased work of breathing. While a respiratory rate of 28 breaths per minute is elevated, a low oxygen saturation is a more critical finding that necessitates prompt attention.

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. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which clinical finding is most concerning to the nurse?

• A. Kussmaul respirations
• B. Blood glucose level of 300 mg/dl
• C. Serum potassium of 3.2 mEq/L
• D. Positive urine ketones

Correct answer: C

Rationale: The correct answer is C: Serum potassium of 3.2 mEq/L. A low serum potassium level in a client with DKA is concerning due to the risk of cardiac arrhythmias. Kussmaul respirations (choice A) are a compensatory mechanism for metabolic acidosis in DKA. A blood glucose level of 300 mg/dl (choice B) is elevated but expected in DKA. Positive urine ketones (choice D) are a classic finding in DKA and not as concerning as low serum potassium.

5. A client with a history of chronic heart failure is admitted with shortness of breath and crackles in the lungs. Which laboratory value should be closely monitored?

• A. Serum creatinine of 2.0 mg/dL
• B. Serum sodium of 135 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Blood glucose of 150 mg/dL

Correct answer: C

Rationale: A serum potassium level of 5.5 mEq/L should be closely monitored in a client with chronic heart failure as it may indicate hyperkalemia, requiring intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias in patients with heart failure. Serum creatinine (Choice A) is important to monitor for kidney function but is not the priority in this case. Serum sodium (Choice B) and blood glucose (Choice D) levels are not typically the primary focus when assessing a client with heart failure presenting with respiratory symptoms and crackles in the lungs.
