Nursing Elites

1. A young adult male is admitted to the emergency department with diabetic ketoacidosis (DKA). His pH is 7.25, HCO3 is 12 mEq/L, and blood glucose is 310 mg/dl. Which action should the nurse implement?

• A. Infuse sodium chloride 0.9% (normal saline)
• B. Prepare an emergency dose of glucagon
• C. Determine the last time the client ate
• D. Check urine for ketone bodies with a dipstick

Correct answer: A

Rationale: In DKA, restoring fluid balance with sodium chloride is a priority to address the dehydration and electrolyte imbalances present in this condition. Choice B, preparing an emergency dose of glucagon, is incorrect because DKA is characterized by insulin deficiency, not glucagon deficiency. Choice C, determining the last time the client ate, is not the immediate priority in managing DKA. Choice D, checking urine for ketone bodies with a dipstick, may help confirm the diagnosis of DKA but is not the most critical intervention at this time.

2. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which clinical finding is most concerning?

• A. Headache
• B. Prothrombin time (PT) of 15 seconds
• C. Elevated liver enzymes
• D. Peripheral edema

Correct answer: A

Rationale: The correct answer is A: Headache. In a client with atrial fibrillation taking warfarin (Coumadin), a headache can be indicative of bleeding, which is a serious complication requiring immediate assessment and intervention. Monitoring for signs of bleeding is crucial when on anticoagulant therapy. Choices B, C, and D are not the most concerning. A prothrombin time of 15 seconds is within the therapeutic range for a client on warfarin, elevated liver enzymes may indicate liver dysfunction but are not directly related to the medication's side effects, and peripheral edema is not typically associated with warfarin use or atrial fibrillation in this context.

3. The nurse plans to administer a scheduled dose of metoprolol (Toprol SR) at 0900 to a client with hypertension. At 0800, the nurse notes that the client's telemetry pattern shows a second-degree heart block with a ventricular rate of 50. What action should the nurse take?

• A. Administer the Toprol immediately and monitor the client until the heart rate increases.
• B. Provide the dose of Toprol as scheduled and assign a UAP to monitor the client's BP q30 minutes.
• C. Give the Toprol as scheduled if the client's systolic blood pressure reading is greater than 180.
• D. Hold the scheduled dose of Toprol and notify the healthcare provider of the telemetry pattern.

Correct answer: D

Rationale: In clients with second-degree heart block, beta blockers such as metoprolol (Toprol SR) are contraindicated as they can further decrease the heart rate. Administering metoprolol in this situation can lead to serious complications. The correct action for the nurse to take is to hold the scheduled dose of Toprol and promptly notify the healthcare provider of the telemetry pattern. This ensures patient safety and appropriate management of the cardiac condition. Choices A, B, and C are incorrect because administering Toprol despite the heart block can worsen the condition and pose a risk to the client's health.

4. 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.

5. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?

• A. 50 ml/hour
• B. 25 ml/hour
• C. 75 ml/hour
• D. 100 ml/hour

Correct answer: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.
