1. A client is being taught about taking warfarin to treat atrial fibrillation. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will take this medication on an empty stomach.
• B. If I forget to take a dose, I can take it later on the same day.
• C. I will skip my dose if I forget to take it.
• D. I can take an additional dose if I miss one.

Correct answer: B

Rationale: The correct answer is B because taking warfarin later on the same day if a dose is missed helps maintain therapeutic levels. Choice A is incorrect because warfarin should be taken with food to enhance absorption. Choice C is incorrect as skipping a dose can lead to fluctuations in warfarin levels. Choice D is incorrect as taking an additional dose can increase the risk of bleeding.

2. A healthcare professional is reviewing the medical records of a client who has a pressure ulcer. Which of the following is an expected finding?

• A. Serum albumin level of 3 g/dL
• B. HDL level of 90 mg/dL
• C. Norton scale score of 18
• D. Braden scale score of 20

Correct answer: A

Rationale: A serum albumin level of 3 g/dL is indicative of poor nutrition, which is commonly associated with pressure ulcers. This finding suggests that the client may be at risk for developing or already has a pressure ulcer due to malnutrition. High-density lipoprotein (HDL) level of 90 mg/dL (Choice B) is not directly related to pressure ulcers. The Norton scale (Choice C) is used to assess a client's risk of developing pressure ulcers, not as a finding in a client with an existing pressure ulcer. The Braden scale (Choice D) is also a tool used to assess the risk of developing pressure ulcers, not a finding in a client with an existing pressure ulcer.

3. A healthcare professional is reviewing the medical record of a client who has a prescription for levothyroxine. Which of the following findings should the healthcare professional identify as an indication of a need for dosage adjustment?

• A. Tremors
• B. Increased appetite
• C. Bradycardia
• D. Diarrhea

Correct answer: B

Rationale: Increased appetite may indicate that the client is experiencing symptoms of hyperthyroidism due to an excessive dose of levothyroxine. This finding suggests a need for a dosage adjustment to prevent potential complications. Tremors are more commonly associated with hyperthyroidism, not necessarily indicating a need for dosage adjustment. Bradycardia and diarrhea are not typical signs of an incorrect levothyroxine dosage and would not directly warrant a need for adjustment.

4. What are key signs of fluid overload?

• A. Edema
• B. Hypertension
• C. Shortness of breath
• D. All of the above

Correct answer: D

Rationale: The correct answer is 'D: All of the above.' Edema, hypertension, and shortness of breath are key signs of fluid overload, particularly common in patients with heart failure. Edema refers to the swelling caused by excess fluid trapped in the body's tissues, hypertension can be a result of fluid volume overload, and shortness of breath can occur due to fluid accumulation in the lungs. Therefore, all these signs collectively indicate fluid overload in a patient. Choices A, B, and C are incorrect individually as each alone may not necessarily indicate fluid overload, but when seen together, they strongly suggest fluid volume excess in the body.

5. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.
