1. A client is receiving discharge teaching for a new prescription of warfarin. Which statement by the client indicates an understanding of the teaching?

A. I will need to increase my intake of leafy green vegetables.
B. I will avoid drinking grapefruit juice while taking warfarin.
C. I will have my INR checked regularly.
D. I will take my medication at the same time each day.

Correct answer: C

Rationale: The correct answer is C. Clients on warfarin therapy need to have their International Normalized Ratio (INR) checked regularly to monitor the medication's effectiveness and prevent complications like clotting or bleeding. Option A is incorrect because increasing leafy green vegetables can affect INR levels due to their vitamin K content. Option B is incorrect as grapefruit juice is not a significant concern with warfarin. Option D is important for medication adherence but does not specifically address the monitoring aspect required for warfarin therapy.

2. What is the best intervention for a patient experiencing hypoxia?

A. Administer oxygen
B. Reposition the patient
C. Provide humidified air
D. Provide chest physiotherapy

Correct answer: A

Rationale: The best intervention for a patient experiencing hypoxia is to administer oxygen. Oxygen therapy helps improve oxygenation levels in the blood, addressing the underlying cause of hypoxia. Repositioning the patient, providing humidified air, and chest physiotherapy may be beneficial in certain situations but are not the primary interventions for hypoxia. Administering oxygen is crucial to quickly alleviate hypoxia and support the patient's respiratory function.

3. A nurse is caring for a client who is receiving continuous enteral nutrition through a nasogastric tube. Which of the following actions should the nurse take?

A. Administer the feeding using a large-bore syringe
B. Check the placement of the tube every 8 hours
C. Flush the tube with 5 mL of water every 6 hours
D. Maintain the client in an upright position

Correct answer: B

Rationale: The correct action for the nurse to take is to check the placement of the nasogastric tube every 8 hours. This is crucial to ensure that the tube is correctly positioned in the stomach, reducing the risk of complications such as aspiration. Administering the feeding using a large-bore syringe (Choice A) is not recommended for enteral nutrition. Flushing the tube with water every 6 hours (Choice C) is not necessary for continuous enteral nutrition. Maintaining the client in an upright position (Choice D) is generally preferred to reduce the risk of aspiration, but it is not the most critical action compared to verifying tube placement.

4. A nurse is caring for a client who has left-sided heart failure. Which of the following findings should the nurse expect?

A. Peripheral edema.
B. Bradycardia.
C. Jugular vein distention.
D. Dependent edema.

Correct answer: C

Rationale: Jugular vein distention is a classic sign of left-sided heart failure due to fluid overload in the pulmonary circulation. This occurs because the heart's left side is unable to pump effectively, causing increased pressure in the pulmonary veins and leading to blood backing up into the pulmonary circulation. Peripheral edema (choice A) and dependent edema (choice D) are more commonly associated with right-sided heart failure where blood pools in the systemic circulation, causing swelling in the extremities. Bradycardia (choice B) is not typically a direct consequence of left-sided heart failure; instead, tachycardia is more commonly seen as the heart compensates for its reduced efficiency.

5. Which electrolyte imbalance is common in patients receiving diuretics?

A. Hypokalemia
B. Hypercalcemia
C. Hyponatremia
D. Hypermagnesemia

Correct answer: A

Rationale: The correct answer is Hypokalemia. Diuretics, such as furosemide, commonly cause potassium loss in patients, leading to hypokalemia. This electrolyte imbalance should be closely monitored to prevent complications like cardiac arrhythmias. Hypercalcemia (Choice B) is not typically associated with diuretic use. Hyponatremia (Choice C) involves low sodium levels and can occur in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH) but is not directly caused by diuretics. Hypermagnesemia (Choice D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.
