1. A patient with hypokalemia is being monitored. What should the nurse assess for?

A. Muscle weakness
B. Flattened T waves
C. Checking deep tendon reflexes
D. Seizures

Correct answer: A

Rationale: Corrected Question: A patient with hypokalemia is being monitored. What should the nurse assess for? Corrected Choice A: Muscle weakness Corrected Choice B: Flattened T waves Corrected Choice C: Checking deep tendon reflexes Corrected Choice D: Seizures Rationale: Hypokalemia is associated with muscle weakness due to the effect of low potassium levels on muscle function. Flattened T waves on an ECG are characteristic of hypokalemia but are not a direct assessment for the patient's condition. Checking deep tendon reflexes and seizures are not primary symptoms associated with hypokalemia, making them less relevant for monitoring a patient with this electrolyte imbalance.

2. What are the expected manifestations of a thrombotic stroke?

A. Gradual loss of function on one side of the body
B. Loss of sensation in the affected extremity
C. Sudden loss of consciousness
D. Seizures and convulsions

Correct answer: A

Rationale: The correct answer is A: Gradual loss of function on one side of the body. Thrombotic strokes are caused by a clot forming in a blood vessel supplying the brain, leading to a gradual onset of symptoms due to impaired blood flow to specific brain regions. Choices B, C, and D are incorrect because loss of sensation, sudden loss of consciousness, seizures, and convulsions are not typically associated with thrombotic strokes. In a thrombotic stroke, the symptoms develop slowly over time, often over minutes to hours, and include manifestations such as weakness, numbness, or paralysis on one side of the body, along with other symptoms related to the affected brain area.

3. What are the signs and symptoms of a hemorrhagic stroke?

A. Sudden severe headache, decreased level of consciousness, and seizures
B. Loss of consciousness and weakness
C. Temporary vision loss
D. Severe chest pain and shortness of breath

Correct answer: A

Rationale: The correct answer is A. A hemorrhagic stroke often presents with a sudden severe headache, decreased level of consciousness, and seizures due to bleeding in the brain. Choice B, loss of consciousness and weakness, is more indicative of an ischemic stroke where a clot blocks blood flow to the brain. Choice C, temporary vision loss, is more commonly seen in conditions like transient ischemic attacks (TIAs) or retinal migraines. Choice D, severe chest pain and shortness of breath, are symptoms more associated with cardiac issues like a heart attack.

4. What is a characteristic sign of hypokalemia on an ECG?

A. Flattened T waves
B. ST elevation
C. Prominent U waves
D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.

5. What are the expected ECG changes in hypokalemia?

A. Flattened T waves
B. ST elevation
C. Wide QRS complex
D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.
