1. Which lab value is critical to monitor in patients receiving warfarin therapy?

• A. Monitor INR
• B. Monitor potassium levels
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial to monitor in patients receiving warfarin therapy. INR measures the blood's ability to clot and is used to ensure that patients are within the therapeutic range for warfarin therapy. This is important to prevent both clotting disorders and bleeding complications. Monitoring potassium levels (choice B) is not directly related to warfarin therapy. Platelet count (choice C) and sodium levels (choice D) are important parameters but are not as critical to monitor specifically for patients on warfarin therapy.

2. A nurse is assessing a client who has right-sided heart failure. Which of the following findings should the nurse expect?

• A. Weight loss.
• B. Bradycardia.
• C. Peripheral edema.
• D. Dry cough.

Correct answer: C

Rationale: The correct answer is C: Peripheral edema. In right-sided heart failure, the heart struggles to pump blood efficiently, leading to fluid backup in the body. This fluid retention commonly manifests as peripheral edema, causing swelling in the legs, ankles, and feet. Choices A, B, and D are incorrect. Weight loss is not typically associated with right-sided heart failure; bradycardia (slow heart rate) is more commonly seen in conditions like hypothyroidism or athletes, not specifically in right-sided heart failure; and a dry cough is more commonly associated with conditions like pneumonia or bronchitis, not typically with right-sided heart failure.

3. A nurse is providing teaching to a client who has a new prescription for albuterol. Which of the following client statements indicates an understanding of the teaching?

• A. I will use this medication to prevent an asthma attack.
• B. I will use this medication for shortness of breath during an asthma attack.
• C. I will take this medication with my daily vitamins.
• D. I will take this medication at bedtime to prevent an asthma attack.

Correct answer: B

Rationale: The correct answer is B because albuterol is used to treat shortness of breath during an asthma attack. Choice A is incorrect as albuterol is a rescue medication used during an asthma attack, not for prevention. Choice C is incorrect as albuterol should not be taken with daily vitamins. Choice D is incorrect as albuterol is not typically taken at bedtime for asthma prevention.

4. Which electrolyte imbalance is most concerning for a patient on loop diuretics?

• A. Hypokalemia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is hypokalemia. Loop diuretics can cause potassium depletion leading to hypokalemia, which is particularly concerning as it can result in cardiac arrhythmias. Hyponatremia (choice B) is not typically associated with loop diuretics. Hyperkalemia (choice C) is less common in patients on loop diuretics. Hypercalcemia (choice D) is not a typical electrolyte imbalance associated with loop diuretics.

5. A client receiving radiation therapy for breast cancer may experience which of the following side effects that the nurse should monitor for?

• A. Fatigue
• B. Nausea
• C. Skin irritation
• D. Weight gain

Correct answer: C

Rationale: During radiation therapy for breast cancer, one common side effect is skin irritation due to the impact of radiation on the skin cells. This side effect should be closely monitored by the nurse. Fatigue may also occur as a side effect of radiation therapy, but skin irritation is more specific to the treatment area and is a priority in this case. Nausea and weight gain are not typically associated with radiation therapy for breast cancer, making them incorrect choices.
