A nurse is preparing to initiate IV access for an older adult client. Which of the following sites should the nurse select when initiating the IV for this client?

Proceed with provision of medical care.

• A. Contact the facility's ethics committee: This is incorrect because it is not an urgent action and it does not address the client's immediate needs. The ethics committee can be consulted later if there are ethical dilemmas or conflicts regarding the client's care.
• B. Obtain consent from the client's employer: This is incorrect because it is not a valid source of consent. The employer has no legal or ethical authority to make decisions for the client, unless they are also a designated surrogate or proxy.
• C. Limit care to comfort measures: This is incorrect because it does not meet the standard of care for an emergency situation. The nurse has a duty to provide life-saving interventions for a client who is unconscious and requires emergency medical procedures, unless there is evidence of a valid advance directive that states otherwise.
• D. Proceed with provision of medical care: This is correct because it follows the principle of implied consent, which assumes that a reasonable person would consent to emergency treatment if they were able to do so. The nurse should document the circumstances and continue to search for family members or other sources of consent.

pH 7.31

Rationale:

A - This is incorrect because weight gain is not expected in clients who have COPD, as they often have difficulty eating and digesting food due to dyspnea and fatigue.

B - This is incorrect because a decrease in anteroposterior diameter of the chest is not typical of COPD, as the condition causes hyperinflation and air trapping in the lungs, leading to an increase in chest size and a barrel-shaped appearance.

C - This is incorrect because HCO3 24 mEq/L is within the normal range for blood bicarbonate levels, which are 22 to 26 mEq/L. Clients who have COPD often have chronic respiratory acidosis, which stimulates the kidneys to retain bicarbonate and increase its levels in the blood to compensate for the low pH.

D - This is correct because pH 7.31 indicates acidosis, which is common in clients who have COPD due to impaired gas exchange and accumulation of carbon dioxide in the blood.
