A nurse is reviewing the laboratory results of a client who has DKA. The client's ABG results are pH 7.30, PaCO₂ 34 mm Hg and HCO₃ 21 mEq/L. The nurse should identify that these values indicate which of the following acid-base imbalances?
Respiratory alkalosis
Metabolic alkalosis
Metabolic acidosis
Respiratory acidosis
The Correct Answer is C
A nurse reviewing the laboratory results of a client who has DKA should identify that the client's ABG results of pH 7.30, PaCO₂ 34 mm Hg and HCO₃ 21 mEq/L indicate metabolic acidosis. Metabolic acidosis is an acid-base imbalance characterized by a low pH (less than 7.35) and a low bicarbonate level (less than 22 mEq/L).
The other options are not correct.
a) Respiratory alkalosis is an acid-base imbalance characterized by a high pH (greater than 7.45) and a low PaCO₂ (less than 35 mm Hg).
b) Metabolic alkalosis is an acid-base imbalance characterized by a high pH (greater than 7.45) and a high bicarbonate level (greater than 26 mEq/L).
d) Respiratory acidosis is an acid-base imbalance characterized by a low pH (less than 7.35) and a high PaCO₂ (greater than 45 mm Hg).

d. Apply the dressing loosely over the incision.
Explanation:
The correct answer is d. Apply the dressing loosely over the incision.
When caring for an older adult client, it is important for the nurse to be sensitive to age-related changes and promote their comfort and well-being. Applying the dressing loosely over the incision allows for beter circulation and ventilation, which can help prevent complications such as skin breakdown and infection.
Option a is not the correct answer. Asking the client to help with the dressing change may not be appropriate, as postoperative clients, especially older adults, may have limited mobility or dexterity. It is the nurse's responsibility to provide the necessary care and support during the dressing change.
Option b is not the correct answer. Waiting for the client to approach the nurse for assistance may lead to delays in care and could potentially compromise the client's healing process. The nurse should proactively assess the client's needs and provide appropriate care.
Option c is not the correct answer. Using paper tape for securing the new dressing does not specifically address sensitivity to age-related changes. While paper tape may be gentle on the skin, it is not the primary consideration in this situation.
By applying the dressing loosely over the incision, the nurse demonstrates sensitivity to age-related changes and promotes the client's comfort and optimal healing. This approach takes into account the potential for decreased skin elasticity and fragility in older adults, allowing for proper circulation and reducing the risk of complications.
Correct Answer is C
Explanation
The nurse should apply a heat pack 5 to 10 minutes prior to the procedure when planning to obtain blood from a newborn via a heel stick. This helps to increase blood flow to the area and makes it easier to obtain the specimen.
a) Puncturing the heel to a depth of 4 mm is too deep and can cause injury to the newborn. The recommended depth for a heel stick is 2.4 mm or less.
b) Withholding feeding prior to collecting the specimen is not necessary.
d) Elevating the newborn's foot for 15 minutes following the procedure is not necessary.
