A nurse is providing information to a client immediately before his scheduled Romberg test.

Which of the following statements should the nurse make?

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.

A. Hypoxemia is a condition of low oxygen levels in the blood. PEEP can actually improve oxygenation by preventing alveolar collapse and increasing functional residual capacity.

B. Tension pneumothorax is a life-threatening condition of air accumulation in the pleural space that causes increased intrathoracic pressure and compresses the lungs, heart, and great vessels. PEEP can increase the risk of tension pneumothorax by creating excessive positive pressure in the airways and alveoli.

C. Malignant hypertension is a severe form of high blood pressure that can cause organ damage and stroke. PEEP can cause a transient increase in blood pressure due to increased intrathoracic pressure, but it does not cause malignant hypertension.

D. Atelectasis is a condition of partial or complete lung collapse due to alveolar collapse or obstruction. PEEP can prevent or treat atelectasis by maintaining positive pressure in the airways and alveoli.
