A patient is on a PCA pump following an abdominal surgery. The order states the client can have 0.5mg morphine every 15 minutes as needed. The client pushed the button 10 times in the past 60 minutes. How many doses did the client receive?

10
The Correct Answer is B
The PCA (patient-controlled analgesia) pump is programmed to deliver a dose of 0.5 mg of morphine every 15 minutes as needed. This setup means that only 1 dose can be administered every 15 minutes, regardless of how many times the patient presses the button.
Since 60 minutes have passed, the maximum number of doses the patient could receive is calculated as follows:
60 minutes/ 15 minutes per dose= 4 doses
Even though the patient pressed the button 10 times, the pump will only deliver a dose every 15 minutes, resulting in 4 doses.

Correct Answer is A
Explanation
A pureed diet is a type of texture-modified diet where food is blended to a smooth consistency to make it easier to swallow. Nectar-thick liquids are liquids that have a slightly thicker consistency than water, which makes them easier for the client to swallow without choking or aspirating.
Options B, C, and D are not appropriate for a client with dysphagia on a pureed diet with nectar-thick liquids. Corn on the cob is a hard, crunchy food that is difficult to puree, while a hamburger and a salad are both difficult to make into a smooth consistency. These foods could pose a choking or aspiration risk for the client.
Correct Answer is A
Explanation
The correct answer is choice A. When performing hygiene care for a client with an indwelling catheter, the nurse should plan to cleanse the catheter from the meatus outward using mild soap and warm water. This helps to prevent infection and ensure proper hygiene. Using the same cleansing cloth for cleaning the perineal area and catheter tubing (choice B) is not recommended as it can cause contamination and increase the risk of infection. The use of chlorhexidine gluconate (CHG) to cleanse the perineal area (choice C) is not necessary for routine catheter care and should only be used for specific indications such as preventing infection during surgery. Therefore, the nurse should always follow proper hygiene protocols and cleanse the catheter from the meatus outward using mild soap and warm water when caring for a client with an indwelling catheter.
