Nursing Elites

1. 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.

2. A female client reports she has not had a bowel movement for 3 days, but now is defecating frequent small amounts of liquid stool. Which action should the nurse implement?

• A. Digitally check the client for a fecal impaction
• B. Administer a laxative to stimulate bowel movement
• C. Increase fluid intake to soften stool
• D. Perform a digital rectal examination

Correct answer: A

Rationale: The correct action for the nurse to implement is to digitally check the client for a fecal impaction. In this scenario, the client's presentation of frequent small amounts of liquid stool after a period of no bowel movement suggests a possible impaction. By performing a digital examination, the nurse can assess for the presence of a blockage that may be causing the symptoms. Administering a laxative (Choice B) without assessing for impaction can worsen the situation. Increasing fluid intake (Choice C) is generally beneficial for bowel health but may not address the immediate issue of a potential impaction. Performing a digital rectal examination (Choice D) is similar to Choice A but is more focused on assessing the rectum itself rather than checking for an impaction.

3. A client with a history of alcoholism is admitted with confusion, ataxia, and nystagmus. Which nursing intervention is a priority for this client?

• A. Monitor for signs of alcohol withdrawal.
• B. Administer thiamine as prescribed.
• C. Provide a quiet environment to reduce confusion.
• D. Initiate fall precautions.

Correct answer: B

Rationale: The correct answer is B: Administer thiamine as prescribed. Administering thiamine is crucial in clients with a history of alcoholism to prevent Wernicke's encephalopathy, which is characterized by confusion, ataxia, and nystagmus. Monitoring for signs of alcohol withdrawal (choice A) is important but not the priority. Providing a quiet environment (choice C) and initiating fall precautions (choice D) are important interventions, but administering thiamine takes precedence due to the risk of Wernicke's encephalopathy.

4. After multiple attempts to stop drinking, an adult male is admitted to the medical intensive care unit (MICU) with delirium tremens. He is tachycardic, diaphoretic, restless, and disoriented. Which finding indicates a life-threatening condition?

• A. Widening QRS complexes and flat T waves
• B. Tachycardia and elevated blood pressure
• C. Restlessness and anxiety
• D. Diaphoresis and dehydration

Correct answer: A

Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.

5. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which assessment finding requires immediate intervention?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Inspiratory crackles

Correct answer: C

Rationale: The correct answer is C. The use of accessory muscles is most concerning in a client with COPD receiving supplemental oxygen as it indicates increased work of breathing, requiring immediate intervention. Oxygen saturation of 90% is acceptable in a client with COPD. A respiratory rate of 24 breaths per minute is slightly elevated but not as critical as the use of accessory muscles. Inspiratory crackles may be present in clients with COPD due to underlying lung changes but do not require immediate intervention unless associated with other concerning symptoms.
