What is the first intervention for a patient admitted with unstable angina?
- A. Administer nitroglycerin
- B. Obtain cardiac enzymes
- C. Start IV fluids
- D. Monitor for chest pain
Correct Answer: A
Rationale: The correct first intervention for a patient admitted with unstable angina is to administer nitroglycerin. Nitroglycerin helps to relieve chest pain by dilating blood vessels and increasing blood flow to the heart, thereby reducing cardiac workload. This intervention aims to alleviate symptoms and prevent further cardiac damage. Obtaining cardiac enzymes (Choice B) is important for diagnosing a myocardial infarction but is not the initial intervention for unstable angina. Starting IV fluids (Choice C) may be indicated in specific cases like hypovolemia but is not the primary intervention for unstable angina. Monitoring for chest pain (Choice D) is essential but taking action to alleviate the pain, like administering nitroglycerin, is the primary focus in the initial management of unstable angina.

What ECG changes are seen in hypokalemia?
- A. Flattened T waves on the ECG
- B. Elevated ST segments on the ECG
- C. Widened QRS complex
- D. Prominent U waves on the ECG
Correct Answer: A
Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.
What is the priority dietary modification for a patient with pre-dialysis end-stage kidney disease?
- A. Limit phosphorus intake to 700 mg/day
- B. Increase potassium intake to 3 g/day
- C. Eat three large meals per day
- D. Restrict protein intake to 1 g/kg/day
Correct Answer: A
Rationale: The correct answer is A: Limit phosphorus intake to 700 mg/day. In patients with pre-dialysis end-stage kidney disease, restricting phosphorus intake is crucial to manage their condition. Excessive phosphorus can lead to mineral and bone disorders, which are common in kidney disease. Choice B, increasing potassium intake, is not the priority and can be harmful as kidney disease often leads to hyperkalemia. Choice C, eating three large meals per day, is not recommended as smaller, frequent meals are usually better tolerated. Choice D, restricting protein intake to 1 g/kg/day, is important in later stages of kidney disease but is not the priority at the pre-dialysis stage.
The nurse misread a patient's glucose as 210 mg/dL instead of 120 mg/dL and administered the insulin dose for a reading over 200 mg/dL. What is the priority action?
- A. Administer glucose IV
- B. Monitor for hyperglycemia
- C. Monitor for hypoglycemia
- D. Document the incident
Correct Answer: C
Rationale: The priority action is to monitor the patient for signs of hypoglycemia as the nurse administered excess insulin due to misreading the glucose level. Administering glucose IV (Choice A) is not the immediate priority when dealing with hypoglycemia. Monitoring for hyperglycemia (Choice B) is not the correct action as the insulin was administered for a higher glucose reading. Documenting the incident (Choice D) is important but not the priority when the patient's safety is at risk due to possible hypoglycemia.
A patient who experienced an acute episode of gastritis should avoid which type of foods?
- A. Avoid foods high in potassium
- B. Avoid foods high in sodium
- C. Increase exercise to reduce stress
- D. Drink milk as a snack
Correct Answer: A
Rationale: The correct answer is A: Avoid foods high in potassium. Potassium-rich foods can exacerbate gastritis symptoms by irritating the stomach lining. Sodium (choice B) is not directly related to gastritis symptoms. Increasing exercise (choice C) can be beneficial for overall health but may not directly impact gastritis. Drinking milk (choice D) can provide temporary relief for some individuals with gastritis due to its coating effect, but it is not a universal recommendation as it can worsen symptoms in some cases.
What dietary recommendations should a patient with GERD follow?
- A. Avoid mint and spicy foods
- B. Consume liquids between meals
- C. Eat three large meals per day
- D. Drink milk as a snack
Correct Answer: A
Rationale: Patients with GERD should follow dietary recommendations to manage their symptoms effectively. Choice A, 'Avoid mint and spicy foods,' is the correct answer. Mint and spicy foods can trigger acid reflux and worsen GERD symptoms. Choice B, 'Consume liquids between meals,' is not the best recommendation as consuming liquids during meals can worsen GERD symptoms by increasing stomach pressure. Choice C, 'Eat three large meals per day,' is incorrect as large meals can exacerbate GERD symptoms; instead, smaller, more frequent meals are recommended. Choice D, 'Drink milk as a snack,' is not ideal as full-fat dairy products like milk can trigger acid reflux in some individuals. Therefore, the best recommendation for a patient with GERD is to avoid mint and spicy foods.
