1. What ECG changes should be monitored in a patient with hypokalemia?

A. Flattened T waves and prominent U waves
B. Elevated ST segments and wide QRS complexes
C. Tall T waves and flattened QRS complexes
D. Widened QRS complexes and decreased P wave amplitude

Correct answer: A

Rationale: The correct answer is A: Flattened T waves and prominent U waves. In hypokalemia, there is a decrease in potassium levels, which can lead to ECG changes such as flattened T waves and prominent U waves. These changes are classic findings associated with hypokalemia. Choices B (Elevated ST segments and wide QRS complexes), C (Tall T waves and flattened QRS complexes), and D (Widened QRS complexes and decreased P wave amplitude) are all incorrect. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia. Tall T waves and flattened QRS complexes, as well as widened QRS complexes and decreased P wave amplitude, do not represent the typical ECG changes seen in hypokalemia.

2. A nurse is caring for a client who has a traumatic brain injury. Which of the following findings should indicate to the nurse the need for immediate intervention?

A. Axillary temperature 37.2°C (99°F)
B. Apical pulse 100/min
C. Respiratory rate 30/min
D. Blood pressure 140/84 mm Hg

Correct answer: C

Rationale: The correct answer is C. The nurse should prioritize airway and breathing in a client with a traumatic brain injury. An increased respiratory rate may indicate CO2 retention, which could lead to increased intracranial pressure. Choice A, axillary temperature 37.2°C (99°F), is within normal range and does not indicate an immediate need for intervention. Choice B, apical pulse 100/min, is slightly elevated but not as critical as respiratory distress in this scenario. Choice D, blood pressure 140/84 mm Hg, is also within normal limits and does not require immediate intervention compared to the respiratory rate.

3. 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.

4. What symptoms are associated with a thrombotic stroke?

A. Gradual loss of function on one side of the body
B. Sudden loss of consciousness
C. Loss of motor function with nausea
D. Severe headache and vomiting

Correct answer: A

Rationale: A thrombotic stroke presents with a gradual loss of function on one side of the body due to a clot blocking blood flow to the brain. This gradual onset distinguishes it from a hemorrhagic stroke with sudden symptoms like loss of consciousness (Choice B), and from other conditions like migraine, which may present with severe headache and vomiting (Choice D). Nausea (Choice C) is not typically a primary symptom associated with a thrombotic stroke.

5. 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.
