1. What are the complications of untreated hypertension?

• A. Heart disease and stroke
• B. Kidney failure and vision loss
• C. Pulmonary embolism and arrhythmias
• D. Blood clots and gastrointestinal bleeding

Correct answer: A

Rationale: The correct answer is A: 'Heart disease and stroke.' Untreated hypertension can lead to various complications, including heart disease and stroke. These are common outcomes of long-term high blood pressure. Choice B, 'Kidney failure and vision loss,' is incorrect as kidney failure and vision loss are more commonly associated with diabetic complications rather than untreated hypertension. Choice C, 'Pulmonary embolism and arrhythmias,' while serious, are not among the primary complications of untreated hypertension. Choice D, 'Blood clots and gastrointestinal bleeding,' are not typical complications of untreated hypertension but can occur due to other conditions such as blood clotting disorders or gastrointestinal diseases.

2. How should a healthcare professional manage a patient with suspected myocardial infarction (MI)?

• A. Administer oxygen and call for emergency help
• B. Monitor vital signs and provide pain relief
• C. Provide nitroglycerin and thrombolytics
• D. Administer diuretics and provide a high-protein diet

Correct answer: A

Rationale: Administering oxygen and seeking emergency help are crucial initial steps in managing a patient with suspected myocardial infarction (MI). Oxygen helps to improve oxygenation to the heart muscle, reducing its workload and preventing further damage. Calling for emergency help ensures timely access to advanced medical care, including interventions like thrombolytics. Monitoring vital signs and providing pain relief are important but secondary to the immediate need for oxygen and emergency assistance. Providing nitroglycerin and thrombolytics should be done under medical supervision and following appropriate protocols, not as the first step. Administering diuretics and altering the patient's diet are not indicated in the acute management of MI.

3. What are the key signs of hyperkalemia and how should it be treated?

• A. Elevated potassium levels, muscle weakness; administer calcium gluconate
• B. Decreased potassium levels, confusion; administer potassium chloride
• C. Elevated sodium levels, bradycardia; administer sodium bicarbonate
• D. Low sodium levels, muscle cramps; administer sodium chloride

Correct answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.

4. What is the correct procedure for taking a telephone order from a provider?

• A. State patient name, drug, dose, route, frequency, and read back the order
• B. State the medication and ask for a witness to listen to the order
• C. Write down the order and verify with the provider within 12 hours
• D. Have the provider verify the order during the next in-person visit

Correct answer: A

Rationale: The correct procedure for taking a telephone order from a provider is to state the patient's name, drug, dose, route, frequency, and then read back the order to ensure accuracy. This process helps in preventing errors and ensures that all relevant information is correctly documented. Choice B is incorrect because having a witness listen to the order is not a standard practice and may not guarantee accuracy. Choice C is incorrect as verifying the order within 12 hours may lead to delays in patient care. Choice D is incorrect because waiting for the provider to verify the order during the next in-person visit could result in a significant delay in administering necessary medication.

5. What is the proper technique for administering an intramuscular (IM) injection?

• A. Locate the injection site and insert at 90 degrees
• B. Insert needle at a 45-degree angle
• C. Massage the site after injection
• D. Insert needle at a 15-degree angle

Correct answer: A

Rationale: The correct technique for administering an intramuscular (IM) injection is to locate the injection site and insert the needle at a 90-degree angle. This angle ensures that the medication is delivered into the muscle for proper absorption. Choice B is incorrect because a 45-degree angle is typically used for subcutaneous injections, not intramuscular. Choice C is incorrect as massaging the site after an injection can cause the medication to disperse unevenly. Choice D is incorrect as a 15-degree angle would not reach the muscle layer effectively for an IM injection.
