Nursing Elites

1. Which lab result would be most indicative of renal failure?

• A. Elevated creatinine levels.
• B. Low potassium levels.
• C. Low calcium levels.
• D. High sodium levels.

Correct answer: A

Rationale: The correct answer is A: Elevated creatinine levels. Creatinine is a waste product that is normally filtered by the kidneys. Elevated creatinine levels indicate impaired kidney function, which is commonly seen in renal failure. Choice B, low potassium levels, is not typically associated with renal failure. In fact, renal failure is more likely to cause high potassium levels due to the kidneys' inability to excrete potassium effectively. Choice C, low calcium levels, are not directly indicative of renal failure. Renal failure can lead to disturbances in calcium levels, but low calcium levels alone are not a specific marker for renal failure. Choice D, high sodium levels, are also not typically associated with renal failure. In renal failure, there may be disturbances in sodium levels, but high sodium levels alone are not a direct indicator of renal failure.

2. A client with heart disease is on a continuous telemetry monitor and has developed sinus bradycardia. In determining the possible cause of the bradycardia, the nurse assesses the client's medication record. Which medication is most likely the cause of the bradycardia?

• A. Propranolol (Inderal).
• B. Captopril (Capoten).
• C. Furosemide (Lasix).
• D. Dobutamine (Dobutrex).

Correct answer: A

Rationale: Propranolol (Inderal) is a beta-adrenergic blocking agent that acts to decrease heart rate and contractility. Sinus bradycardia is a common side effect of beta blockers due to their negative chronotropic effect on the heart. Captopril (Capoten) is an ACE inhibitor used for hypertension and heart failure, not associated with causing bradycardia. Furosemide (Lasix) is a loop diuretic that can lead to electrolyte imbalances but not commonly linked to bradycardia. Dobutamine (Dobutrex) is a beta-1 adrenergic agonist that increases heart rate and contractility, making it an unlikely cause of bradycardia in this scenario.

3. During CPR, when attempting to ventilate a client's lungs, the nurse notes that the chest is not moving. What action should the nurse take first?

• A. Use a laryngoscope to check for a foreign body lodged in the airway.
• B. Reposition the head to ensure that the airway is properly opened.
• C. Turn the client to the side and administer three back blows.
• D. Perform a finger sweep of the mouth to clear any obstructions.

Correct answer: B

Rationale: The most common reason for inadequate lung aeration during CPR is the incorrect positioning of the head, leading to airway obstruction. Therefore, the initial action should be to reposition the head to open the airway properly and attempt to ventilate again. Using a laryngoscope to check for foreign bodies in the airway (Choice A) is not the first step and could delay crucial interventions. Turning the client to the side and administering back blows (Choice C) is not indicated in this scenario as the focus is on ventilating the lungs. Performing a finger sweep of the mouth (Choice D) is not recommended as it may push obstructions further into the airway during CPR.

4. The nurse observes an increased number of blood clots in the drainage tubing of a client with continuous bladder irrigation following a transurethral resection of the prostate (TURP). What is the best initial nursing action?

• A. Provide additional oral fluid intake
• B. Measure the client's intake and output
• C. Increase the flow of the bladder irrigation
• D. Administer a PRN dose of an antispasmodic agent

Correct answer: C

Rationale: The best initial nursing action when observing an increased number of blood clots in the drainage tubing of a client with continuous bladder irrigation post-TURP is to increase the flow of the bladder irrigation. This action helps prevent blood clots from obstructing the catheter, ensuring effective drainage and promoting client comfort. Providing additional oral fluid intake (Choice A) is important for overall hydration but may not directly address the issue of blood clots in the drainage tubing. Measuring the client's intake and output (Choice B) is a routine nursing assessment that may not directly address the immediate concern of blood clots obstructing the catheter. Administering a PRN dose of an antispasmodic agent (Choice D) is not the best initial action as it does not directly address the issue of blood clots in the drainage tubing.

5. A client who has heart failure is admitted with a serum potassium level of 2.9 mEq/L. Which action is most important for the nurse to implement?

• A. Administer 20 mEq of potassium chloride.
• B. Initiate continuous cardiac monitoring.
• C. Arrange a consultation with the dietitian.
• D. Educate about the side effects of diuretics.

Correct answer: B

Rationale: Hypokalemia, defined as a serum potassium level below the normal range of 3.5 to 5 mEq/L, can lead to changes in myocardial irritability and ECG waveform, potentially causing life-threatening dysrhythmias. Therefore, the priority action for the nurse is to initiate continuous cardiac monitoring to promptly detect any abnormal heart rhythms or ventricular ectopy. This monitoring is crucial for assessing the impact of potassium replacement therapy on the cardiac rhythm and ensuring the safety of the client. While administering potassium chloride is important for correcting the hypokalemia, it should occur after cardiac monitoring is in place. Consulting with a dietitian and educating about diuretic side effects are relevant aspects of care but are not the immediate priority in this situation where cardiac monitoring takes precedence for timely intervention.
