. A nurse is preparing to administer 0.9% sodium chloride 1 L IV to infuse over 8 hr. The drop factor of the manual IV tubing set is 15 gtts/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["31"]

Desired volume: 1 L = 1,000 mL

Infusion time: 8 hours = 480 minutes

Drop factor: 15 gtts/mL

Formula: (Volume (mL) ÷ Time (min)) × Drop factor (gtts/mL)

= (1000 ÷ 480) × 15

= 31.25

Rounded to the nearest whole number: 31 gtt/min

Correct Answer is C

Explanation

A. The stockings replace the need for postoperative leg exercises: Antiembolism stockings help reduce the risk of clots, but they do not replace the need for postoperative leg exercises, which help maintain circulation and prevent deep vein thrombosis (DVT).

B. The stockings prevent varicose veins: Antiembolism stockings are primarily used to prevent blood clots, such as DVT, not to treat or prevent varicose veins.

C. The stockings help to improve circulation and reduce the risk for clots: Antiembolism stockings are designed to promote venous return to the heart by applying graduated pressure to the legs, which helps improve circulation and reduce the risk of developing blood clots postoperatively.

D. The stockings are used to reduce pain: Antiembolism stockings are not intended to relieve pain. Their primary purpose is to prevent venous stasis and thromboembolism, especially in postoperative and immobile clients.

A. Use alcohol pad to wipe the skin before placing the electrodes B. No movement during the test, you should try to lay still. C. Inspect electrodes while preparing for test D. Administer an analgesic prior to the procedure E. Instruct the client to breath normally F. Keep the client NPO after midnight.

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

Explanation

A. Use alcohol pad to wipe the skin before placing the electrodes: Cleaning the skin with alcohol before applying the electrodes helps remove oils and dirt, ensuring better contact and more accurate readings.

B. "No movement during the test, you should try to lay still." The client should remain still during the ECG to avoid muscle movements or artifacts that can interfere with the ECG tracing.

C. Inspect electrodes while preparing for test: Inspecting electrodes ensures that they are functioning correctly and are not damaged, which can affect the accuracy of the ECG.

D. Administer an analgesic prior to the procedure: An analgesic is not necessary for an ECG as the procedure is non-invasive and painless.

E. Instruct the client to breathe normally: Instructing the client to breathe normally helps avoid unnecessary movement of the chest, which could distort the ECG tracing.

F. Keep the client NPO after midnight: There is no need to keep the client NPO for an ECG, as it is not a procedure requiring sedation or fasting.
