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?

Radial vein of the inner arm

Great saphenous vein of the leg

Dorsal plexus vein of the foot

Basilic vein of the hand

Answer and Explanation

The Correct Answer is A

- A. Radial vein of the inner arm. This is correct because this site is easily accessible, has good blood flow, and has less risk of complications such as infection, thrombosis, or infiltration.

- B. Great saphenous vein of the leg. This is incorrect because this site is not recommended for older adults due to poor circulation, increased risk of thrombophlebitis, and difficulty in monitoring.

- C. Dorsal plexus vein of the foot. This is incorrect because this site is prone to edema, infection, and injury, and can interfere with mobility and comfort.

- D. Basilic vein of the hand. This is incorrect because this site is more painful, has smaller veins, and can cause nerve damage or occlusion if not inserted carefully.

Correct Answer is C

Explanation

Respiratory acidosis.

Rationale:

A. Incorrect. The client does not have respiratory alkalosis because respiratory alkalosis is characterized by a low PaCO2 (less than 35 mm Hg) and a high pH (greater than 7.45).
B. Incorrect. The client does not have metabolic alkalosis because metabolic alkalosis is characterized by a high HCO3 (greater than 26 mEq/L) and a high pH (greater than 7.45). - C. Correct. The client has respiratory acidosis because respiratory acidosis is characterized by a high PaCO2 (greater than 45 mm Hg) and a low pH (less than 7.35).
D. Incorrect. The client does not have metabolic acidosis because metabolic acidosis is characterized by a low HCO3 (less than 22 mEq/L) and a low pH (less than 7.35).

A. Assess peripheral circulation hourly. B. Assess the client's mouth every 8 hr. C. Use humidification with oxygen therapy. Administer IV fluids. D. Raise the knee position on the client's bed. E. Use an automated blood pressure cuff on the client's arm. Prepare for platelet transfusion.

Correct Answer is ["A","B","C"]

Explanation

A. Assess peripheral circulation hourly. This is correct because clients with SCD are at risk of vaso-occlusive crisis, which can impair blood flow to the extremities and cause tissue ischemia and necrosis. The nurse should monitor for signs of poor circulation such as pallor, coolness, numbness, or pain.

B. Assess the client's mouth every 8 hr. This is correct because clients with SCD are prone to oral ulcers, infections, and dental problems due to chronic anemia and reduced oxygen delivery to the oral mucosa. The nurse should inspect the mouth for lesions, bleeding, inflammation, or infection and provide oral hygiene as needed.

C. Use humidification with oxygen therapy. Administer IV fluids. This is correct because clients with SCD need adequate hydration and oxygenation to prevent sickling of red blood cells and further complications. Humidification helps moisten the airways and prevent dehydration of the mucous membranes. IV fluids help maintain fluid and electrolyte balance and reduce blood viscosity.

D. Raise the knee position on the client's bed. This is incorrect because this can impede venous return and worsen peripheral circulation. The nurse should keep the client's extremities in a neutral position and avoid tight or restrictive clothing or devices.

E. Use an automated blood pressure cuff on the client's arm. Prepare for platelet transfusion. This is incorrect because this can cause mechanical trauma to the arm and trigger a vasoocclusive crisis. The nurse should use a manual blood pressure cuff and avoid applying pressure to the arm. Platelet transfusion is not indicated for clients with SCD unless they have thrombocytopenia or bleeding.
