Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. The nurse is caring for a client with a diagnosis of pneumonia who has been febrile for 24 hours. Which data is most important for the nurse to obtain in determining the client's fluid status?

• A. Daily intake and output
• B. Skin turgor
• C. Daily weight
• D. Vital signs every 4 hours

Correct answer: C

Rationale: Daily weight is the most important data for the nurse to obtain in determining the client's fluid status in this scenario. During febrile episodes, assessing daily weight is crucial as it can indicate fluid retention or loss. While monitoring intake and output is important for assessing fluid balance, daily weight provides a more comprehensive picture of fluid status over time. Skin turgor is more indicative of hydration status than overall fluid status, and vital signs, although essential, do not directly assess fluid status as effectively as daily weight.

3. The nurse is preparing to administer a unit of packed red blood cells (PRBCs) to a client. Which action is most important for the nurse to take?

• A. Verify the client's blood type
• B. Ensure the PRBCs are warm
• C. Check the client's vital signs
• D. Obtain the client's consent

Correct answer: A

Rationale: Verifying the client's blood type is crucial before administering PRBCs to ensure compatibility and prevent transfusion reactions. Checking the client's blood type is essential in blood transfusions. Ensuring the PRBCs are warm is not a priority as the temperature should be within a specific range regardless of the client's preference. Checking the client's vital signs is important but not as crucial as verifying the blood type before a blood transfusion. Obtaining the client's consent is important for any procedure but does not directly impact the safety and success of administering PRBCs.

4. The nurse is caring for a client who has a chest tube in place following a pneumothorax. The nurse notes that there is continuous bubbling in the water seal chamber of the chest tube drainage system. What action should the nurse take?

• A. Check for kinks in the tubing
• B. Notify the healthcare provider
• C. Replace the chest tube drainage system
• D. Reinforce the chest tube dressing

Correct answer: B

Rationale: The correct action for the nurse to take when observing continuous bubbling in the water seal chamber of the chest tube drainage system is to notify the healthcare provider. Continuous bubbling indicates a possible air leak, and the healthcare provider needs to be informed to assess the situation and take appropriate actions. Checking for kinks in the tubing (Choice A) may be done initially but is not the priority when continuous bubbling is present. Replacing the chest tube drainage system (Choice C) and reinforcing the chest tube dressing (Choice D) are not immediate actions needed in response to continuous bubbling in the water seal chamber.

5. The nurse offers diet teaching to a female college student who was diagnosed with iron-deficiency anemia following her voluntary adoption of a lacto-vegetarian diet. What nutrients should the nurse suggest this client eat to best meet her nutritional needs while allowing her to adhere to a lacto-vegetarian diet?

• A. Drink whole milk instead of skim milk to enhance the body's production of amino acids
• B. Take vitamin K 10mg PO daily to enhance production of red blood cells
• C. Increase amounts of dark yellow vegetables such as carrots to fortify iron stores
• D. Combine several legumes and grains such as beans and rice to form complete proteins

Correct answer: D

Rationale: Combining legumes and grains ensures the client receives all essential amino acids to form complete proteins, which is crucial in a vegetarian diet. Options A, B, and C are incorrect. Option A is not necessary as there are plant-based sources of essential amino acids in a lacto-vegetarian diet. Option B suggests vitamin K, which is not directly related to enhancing red blood cell production. Option C mentions increasing dark yellow vegetables, which are sources of non-heme iron, but combining legumes and grains is more effective in addressing the protein needs of a lacto-vegetarian.
