A nurse is assessing a client who received 2 units of packed RBCs 48 hr ago. Which of the following findings should indicate to the nurse that the therapy has been effective?
Hemoglobin 14.9 g/dL
WBC count 12.000/mm
Potassium 48 mEq
BUN 18 mg/dL
The Correct Answer is A
- A. Correct. A hemoglobin level of 14.9 g/dL indicates that the client has an adequate amount of oxygen-carrying capacity in the blood, which is the goal of blood transfusion therapy.
- B. Incorrect. A WBC count of 12,000/mm3 is slightly elevated and may indicate an infection or inflammation, which are not related to blood transfusion therapy.
- C. Incorrect. A potassium level of 48 mEq/L is dangerously high and may cause cardiac arrhythmias, muscle weakness, or paralysis. This is not an expected outcome of blood transfusion therapy and may indicate hemolysis or renal impairment.
- D. Incorrect. A BUN level of 18 mg/dL is within the normal range and does not reflect the effectiveness of blood transfusion therapy.

Correct Answer is C
Explanation
Choice A rationale:
Keeping a can of concentrated formula in the refrigerator for 3 days after opening it is not safe. Once a can of formula is opened, it should be used within 24 hours and stored in the refrigerator. After 24 hours, any leftover formula should be discarded to prevent the risk of bacterial contamination.
Choice B rationale:
Diluting ready-to-feed formula with water is incorrect. Ready-to-feed formula is already prepared and does not need to be diluted further. Adding water to ready-to-feed formula can dilute its nutritional content and may not provide the necessary nutrients for the baby.
Choice C rationale:
Boiling tap water for 2 minutes and cooling it before mixing it with powdered formula is the correct method for safe formula preparation. Boiling the water kills harmful bacteria and ensures the formula is safe for the baby to consume. It is essential to cool the boiled water before mixing it with powdered formula to reach an appropriate feeding temperature.
Choice D rationale:
Ensuring that all bottles contain BPA (bisphenol A) is not a relevant consideration for formula preparation. BPA is a chemical that was previously used in some plastics, including baby bottles, but has been banned in baby bottles and sippy cups in several countries due to its potential health risks. Most modern baby bottles are BPA-free, and this statement does not address the safe handling and preparation of formula for the baby.
Correct Answer is B
Explanation
Choice B rationale:
Instructing the client to gently stroke her lower abdomen is the appropriate action in this situation. Gentle stroking or tapping on the lower abdomen can stimulate the bladder reflex and promote urination. This technique can help clients who have difficulty voiding, especially when using a bedpan. It encourages relaxation of the pelvic muscles, making it easier for the client to urinate.
Choice A rationale:
Turning on the faucets in the client's sink is not a recommended action for promoting urination. While the sound of running water can sometimes trigger the need to urinate, it may not be effective for every individual. Moreover, this action may not be practical or feasible in all healthcare settings.
Choice C rationale:
Instructing the client to lean slightly backward is not an appropriate action for promoting urination. Leaning backward can put pressure on the bladder, which may make it more challenging for the client to urinate. Encouraging relaxation and using techniques like gentle abdominal stroking are more effective in this situation.
Choice D rationale:
Pouring cool water over the client's perineum is not a recommended action for promoting urination. While some individuals find warm water soothing and relaxing, pouring cold water may cause discomfort and stress, making it even more difficult for the client to urinate. Gentle stimulation and relaxation techniques are generally more effective.
