A nurse is preparing to administer valproate 750 mg PO to an adult client who has bipolar disorder. The client refuses to swallow capsules but consents to swallow an oral solution of the medication. Available is valproate oral solution 250 mg/5 mL. How many mL of valproate should the nurse plan to administer? (Round 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 ["15"]

750 mg (desired dose) divided by 250 mg (available concentration) equals 3. This result is then multiplied by the volume that contains 250 mg, which is 5 mL. So, 3 times 5 mL equals 15 mL.

Therefore, the nurse should plan to administer 15 mL of the valproate oral solution

Correct Answer is C

Explanation

A. Place the client in a high Fowler's position:High Fowler’s would increase intra-abdominal pressure and strain sutures. For peritonitis recovery, semi-Fowler’s is preferred-promotes drainage of peritoneal fluid into the pelvis, preventing spread to diaphragm and lungs.

B. Ambulate the client twice daily:Too early after peritonitis lavage. Initially, the client is very weak, at risk for sepsis/shock. Early ambulation is not a priority here.

C. Mark abdominal girth once daily:Abdominal girth measurement is important to monitor for distention, fluid accumulation, or bleeding. Marking ensures accuracy in repeated measurements. This is a key intervention in monitoring postop peritonitis.

D. Irrigate the nasogastric tube with tap water:Never irrigate with tap water (risk of electrolyte imbalance, infection). Only sterile normal saline or as prescribed is used.

A. Clamp the chest tubes if it becomes disconnected B. Maintain the drainage container below the level of the client's chest. C. Empty the collection container every shift. D. Add tap water as needed to the suction control chamber.

Correct Answer is B

Explanation

A. Clamping the chest tubes is contraindicated because it can lead to tension pneumothorax, a life- threatening condition where air accumulates in the pleural space under pressure. If the chest tube becomes disconnected, the nurse should immediately place the end of the tube in sterile water to maintain the water seal and prevent air from entering the pleural space.
B. The drainage container must always be kept below the level of the client's chest. This position allows gravity to facilitate drainage from the pleural space into the collection chamber. If the container is positioned above the client's chest, drainage could potentially flow back into the pleural space, leading to complications.
C. It is essential to monitor and record the amount and characteristics of drainage regularly. Emptying the collection container at least once every shift ensures accurate measurement of drainage output and helps in assessing the client's response to treatment.
D. The water-seal chamber of the chest drainage system maintains the desired amount of suction (usually
-20 cm H2O) to facilitate lung re-expansion. This chamber should be filled with sterile water to the recommended level, usually marked on the device. Adding tap water can introduce contaminants and should be avoided.
