Nursing Elites

1. A nurse in a rural community center is providing education to a group of clients about first aid interventions for snake bites. Which of the following instructions should the nurse include in the teaching?

• A. Apply an ice pack directly to the affected area
• B. Immobilize the affected extremity with a splint
• C. Place a tourniquet above and below the affected area
• D. Elevate the affected extremity

Correct answer: B

Rationale: The correct answer is to immobilize the affected extremity with a splint. This helps to slow the spread of venom by limiting movement. Applying an ice pack directly to the affected area (Choice A) is not recommended for snake bites as it could exacerbate tissue damage. Placing a tourniquet above and below the affected area (Choice C) is also not advised as it can lead to further complications. Elevating the affected extremity (Choice D) is not recommended for snake bites; keeping it below the level of the heart is more appropriate to reduce venom spread.

2. A patient experiencing wheezing due to an allergic reaction needs immediate treatment. Which medication should be administered first?

• A. Albuterol via nebulizer
• B. Cromolyn via nebulizer
• C. Aminophylline IV
• D. Methylprednisolone IV

Correct answer: A

Rationale: The correct answer is A: Albuterol via nebulizer. Albuterol is a rapid-acting bronchodilator that helps relieve wheezing by opening up the airways. During an allergic reaction causing wheezing, prompt relief is crucial, making Albuterol the first-line treatment. Choice B, Cromolyn via nebulizer, is used more for preventing asthma symptoms rather than providing immediate relief. Choice C, Aminophylline IV, is a bronchodilator with a slower onset of action compared to Albuterol. Choice D, Methylprednisolone IV, is a corticosteroid used to reduce inflammation and is not the first-line treatment for acute wheezing in an allergic reaction.

3. 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.

4. A patient has been diagnosed with a thrombotic stroke. What are the expected manifestations?

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

Correct answer: A

Rationale: The correct answer is A: 'Gradual loss of function on one side of the body.' Thrombotic strokes lead to slow and progressive symptoms as a result of decreased blood flow to a specific area of the brain. Choices B, C, and D are incorrect because sudden loss of consciousness, seizures, confusion, and loss of sensation in the affected limb are not typical manifestations of a thrombotic stroke.

5. A nurse is caring for a client who has been experiencing repeated tonic-clonic seizures over the course of 30 minutes. After maintaining the client's airway and turning the client on their side, which of the following medications should the nurse administer?

• A. Diazepam IV
• B. Lorazepam PO
• C. Diltiazem IV
• D. Clonazepam PO

Correct answer: A

Rationale: In the scenario described, where the client has been experiencing repeated tonic-clonic seizures over an extended period, the priority is to administer a medication that can rapidly terminate the seizures. Diazepam is the medication of choice for status epilepticus due to its rapid onset of action within 10 minutes when administered intravenously. Lorazepam is also an option, but it is typically administered intravenously as well. Diltiazem is a calcium channel blocker used for conditions like hypertension and angina, not for seizures. Clonazepam, although used for seizures, is not the ideal choice in this acute situation due to its slower onset of action compared to benzodiazepines like diazepam and lorazepam.
