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?

- A. Instructing the client about the importance of regular medical appointments is important but not the priority because it is a secondary prevention strategy that aims to detect and treat any complications or changes in the client's condition early. The client should have regular follow-up visits with an endocrinologist, a diabetes educator, an ophthalmologist, a podiatrist, a dentist, and other health care providers as needed.

- B. Encouraging the client to participate in daily exercise is important but not the priority because it is a tertiary prevention strategy that aims to reduce disability and improve quality of life for clients with chronic conditions. Exercise can help lower blood glucose levels, improve insulin sensitivity, reduce cardiovascular risk factors, enhance mood, and promote weight management for clients with type 1 diabetes mellitus. The client should consult with their health care provider before starting an exercise program and follow safety guidelines such as checking blood glucose levels before and after exercise, wearing appropriate footwear and clothing, carrying a source of fast-acting carbohydrate, and staying hydrated.

- C. Explaining proper foot care techniques to the client is important but not the priority because it is a tertiary prevention strategy that aims to prevent or minimize complications such as foot ulcers, infections, and amputations for clients with type 1 diabetes mellitus. Foot care includes inspecting feet daily for any injuries or abnormalities, washing feet with mild soap and warm water, drying feet thoroughly especially between toes, applying moisturizer to prevent dryness and cracking, trimming toenails straight across and filing edges smooth, wearing clean cotton socks and well-fitting shoes, avoiding walking barefoot or exposing feet to extreme temperatures or pressure, and seeking medical attention for any foot problems.

- D. Ensuring that the client understands the medication regimen is the nurse's priority because type 1 diabetes mellitus requires lifelong insulin therapy to maintain blood glucose levels within normal range and prevent complications such as ketoacidosis, hypoglycemia, and organ damage. The client needs to know how to administer insulin injections, monitor blood glucose levels, adjust insulin doses according to carbohydrate intake and physical activity, recognize and treat signs and symptoms of hypo- and hyperglycemia, and store insulin properly.

Choice A rationale:

Sodium level of 142 mEq/L is within the normal range (135-145 mEq/L) for adults. However, normal ranges for children might vary slightly, but 142 mEq/L is not indicative of dehydration on its own.

Choice B rationale:

Respiratory rate of 22/min is within the normal range for a 3-year-old child (20-30 breaths/min) This rate alone does not provide evidence of dehydration.

Choice C rationale:

Potassium level of 3.9 mEq/L is within the normal range (3.5-5.1 mEq/L) for children. Like sodium, normal ranges for potassium may differ slightly in pediatric patients, but 3.9 mEq/L is not alarming on its own.

Choice D rationale:

Heart rate of 148/min is elevated for a 3-year-old child. Tachycardia is a common sign of dehydration in pediatric patients. This increased heart rate indicates the body's compensatory mechanism to maintain cardiac output in response to decreased blood volume, a typical consequence of dehydration.
