A nurse is reviewing the ABG values of a client. The client has a pH of 7.2, PaCO2 of 60 mm Hg, and HCO3 of 25 mEq/L. The nurse should identify that the client has which of the following acid-base imbalances?

Use a reward system to modify the child's behavior.

Rationale:

• A. Incorrect. Maintaining a flexible daily schedule for the child may increase their anxiety and confusion, as they may have difficulty adapting to changes in routine and expectations. The nurse should advise the parents to establish a consistent and structured schedule for the child, with clear rules and boundaries.
• B. Correct. Using a reward system to modify the child's behavior is an effective strategy to reinforce positive behaviors and reduce negative ones. The nurse should help the parents identify specific and measurable goals for the child, and provide them with praise, tokens, or privileges when they achieve them.
• C. Incorrect. Providing a variety of family members to care for the child may overwhelm them and impair their social skills development, as they may have difficulty forming attachments and communicating with different people. The nurse should encourage the parents to select one or two primary caregivers for the child, who can provide them with consistent and supportive interactions.
• D. Incorrect. Administering alprazolam as needed to reduce the child's anxiety is not recommended, as it may cause adverse effects such as sedation, dependence, or withdrawal symptoms. The nurse should educate the parents about nonpharmacological interventions for anxiety, such as relaxation techniques, cognitive behavioral therapy, or social skills training.

Choice A rationale:

Initiating IV access on the palmar side of the client's wrist is not recommended. This area has many delicate structures and is prone to complications such as nerve damage. Choosing a safer, larger vein proximal to the wrist is a better practice.

Choice B rationale:

Inserting a larger gauge IV catheter is not necessary unless the client's condition or prescribed therapy specifically requires it. Using an unnecessarily large catheter can cause discomfort and increase the risk of complications, such as phlebitis.

Choice C rationale:

Choosing the client's dominant arm for IV access whenever possible is not a universally appropriate guideline. The choice of the arm should depend on the condition of the veins and the individual patient's circumstances. The nurse should assess both arms and choose the one with the most suitable and accessible veins.

Choice D rationale:

Selecting a site proximal to previous venipuncture sites is the correct action. Repeated venipuncture in the same area can cause phlebitis and compromise the integrity of the veins. Selecting a new site proximal to previous punctures helps to preserve vein health and reduce the risk of complications.
