Nursing Elites

1. What are the expected changes on an ECG for a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. ST elevation
• D. Wide QRS complexes

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

2. What is the first medication to give for wheezing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Cromolyn 20 mg via nebulizer
• C. Methylprednisolone 100 mg IV
• D. Aminophylline 500 mg IV

Correct answer: A

Rationale: Albuterol is the first-line medication for treating wheezing due to an allergic reaction. Albuterol is a short-acting beta-agonist that helps relieve bronchospasm quickly. Cromolyn is more commonly used for the prevention of asthma symptoms rather than for acute treatment. Methylprednisolone and aminophylline are not the first-line medications for acute wheezing due to an allergic reaction.

3. What should the nurse do if a patient experiences abdominal cramping during enema administration?

• A. Lower the height of the solution container
• B. Increase the flow of the enema solution
• C. Stop the procedure and remove the tubing
• D. Continue the enema at a slower rate

Correct answer: A

Rationale: When a patient experiences abdominal cramping during enema administration, the nurse should lower the height of the solution container. This adjustment can help alleviate the cramping by reducing the speed and pressure of the solution entering the colon. Increasing the flow of the enema solution (Choice B) can exacerbate the cramping. Stopping the procedure and removing the tubing (Choice C) may be necessary in extreme cases but is not the initial step. Continuing the enema at a slower rate (Choice D) may not effectively address the cramping, making it less optimal than lowering the height of the solution container.

4. What are the expected manifestations in a patient experiencing a thrombotic stroke?

• A. Sudden numbness or loss of function on one side of the body
• B. Sudden loss of consciousness and seizure
• C. Gradual onset of difficulty speaking
• D. Loss of sensation in the affected limb

Correct answer: A

Rationale: The correct manifestation in a patient experiencing a thrombotic stroke is sudden numbness or loss of function on one side of the body. This is due to the blockage of a blood vessel by a clot, leading to a lack of blood flow to a specific part of the brain. Choices B, C, and D are incorrect. Sudden loss of consciousness and seizure are more commonly associated with hemorrhagic strokes. Gradual onset of difficulty speaking is often seen in ischemic strokes affecting language areas, not specifically in thrombotic strokes. Loss of sensation in the affected limb is more indicative of sensory nerve damage rather than the motor deficits seen in thrombotic strokes.

5. What is the priority action for a patient with chest pain from acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Check the patient's cardiac enzymes
• C. Administer aspirin
• D. Obtain IV access

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This medication helps dilate the blood vessels, reducing the workload of the heart and improving blood flow to the heart muscle, which is crucial in the management of acute coronary syndrome. Checking cardiac enzymes (choice B) is important for diagnosing a heart attack but is not the priority over providing immediate relief to the patient's chest pain. Administering aspirin (choice C) is also important in acute coronary syndrome to prevent further clot formation, but it is not the priority action for immediate pain relief. Obtaining IV access (choice D) is necessary for administering medications or fluids; however, in this scenario, providing sublingual nitroglycerin for prompt pain relief takes precedence.
