Nursing Elites

1. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

2. A nurse is teaching a client who has hypertension about managing blood pressure. Which of the following statements should the nurse make?

• A. Increase your intake of red meat to manage your blood pressure.
• B. You should avoid drinking alcohol while taking this medication.
• C. Exercise for at least 30 minutes most days of the week.
• D. Limit your fluid intake to 3 liters per day.

Correct answer: C

Rationale: The correct statement is C: 'Exercise for at least 30 minutes most days of the week.' Regular exercise is essential in managing blood pressure as it helps improve cardiovascular health. Choice A is incorrect as increasing red meat intake can be detrimental due to its high saturated fat content, which can negatively impact blood pressure. Choice B is not directly related to managing blood pressure unless the medication interacts negatively with alcohol. Choice D, limiting fluid intake to 3 liters per day, is not a general recommendation for managing blood pressure unless specifically advised by a healthcare provider.

3. A nurse is caring for a client who has an indwelling urinary catheter. Which of the following interventions should the nurse implement to prevent catheter-associated infections?

• A. Change the catheter every 24 hours
• B. Ensure the drainage bag is positioned above the bladder
• C. Perform routine irrigation of the catheter
• D. Empty the drainage bag every 4 hours

Correct answer: B

Rationale: The correct answer is to ensure the drainage bag is positioned above the bladder. This positioning prevents urine reflux into the bladder, reducing the risk of catheter-associated infections. Changing the catheter too frequently (Choice A) can actually increase the risk of infection by introducing pathogens. Performing routine catheter irrigation (Choice C) is no longer recommended as it can increase the risk of infection by introducing bacteria. Emptying the drainage bag every 4 hours (Choice D) is a standard practice to prevent urinary stasis but is not directly related to preventing catheter-associated infections.

4. A nurse is preparing to administer digoxin to a client who has heart failure. Which of the following findings should the nurse report to the provider?

• A. Potassium 4.0 mEq/L
• B. Calcium 9.5 mg/dL
• C. Heart rate of 60/min
• D. Sodium 140 mEq/L

Correct answer: C

Rationale: The correct answer is C: Heart rate of 60/min. A heart rate of 60/min is borderline bradycardia, which can be a sign of digoxin toxicity. Digoxin can cause bradycardia, so any further decrease in heart rate should be reported promptly to the healthcare provider. Choices A, B, and D are within the normal range and not specifically related to potential digoxin toxicity, so they do not require immediate reporting.

5. A nurse is caring for a client who has depression and reports taking St. John's Wort along with citalopram. The nurse should monitor the client for which condition as a result of an interaction between these substances?

• A. Tardive dyskinesia.
• B. Serotonin syndrome.
• C. Pseudoparkinsonism.
• D. Acute dystonia.

Correct answer: B

Rationale: The correct answer is B: Serotonin syndrome. Serotonin syndrome can occur due to the interaction between citalopram, an SSRI, and St. John's Wort, an herbal supplement. Symptoms of serotonin syndrome include confusion, agitation, rapid heart rate, high blood pressure, dilated pupils, loss of muscle coordination, and sweating. Choices A, C, and D are incorrect as they are not typically associated with the interaction between citalopram and St. John's Wort. Tardive dyskinesia is a movement disorder associated with long-term use of certain medications, pseudoparkinsonism is a side effect of certain antipsychotic medications, and acute dystonia is a movement disorder caused by certain medications like antipsychotics.
