A client is using a PCA pump with a lockout interval of 15 minutes for pain management. What is the primary purpose of this lockout feature?
To prevent the patient from using too little medication.
To remind the patient of the medication schedule.
To prevent overdosing by enforcing a minimum interval between doses.
To allow the nurse to control medication administration.
The Correct Answer is C
Choice A reason: The lockout feature does not ensure adequate medication use. It is designed to prevent excessive dosing, not to encourage more frequent use. Patients are educated to self-administer based on pain levels.
Choice B reason: PCA pumps are patient-controlled and do not operate on a fixed schedule. The lockout interval is not a reminder tool but a safety mechanism to regulate dosing frequency.
Choice C reason: The lockout interval is a safety feature that prevents the patient from receiving another dose until a specified time has passed. This minimizes the risk of overdose and ensures safe administration of opioids or other analgesics.
Choice D reason: PCA pumps are designed for patient autonomy in pain control. Nurses monitor usage and effectiveness but do not control administration directly. The lockout feature is built into the device, not managed manually by nursing staff.

Correct Answer is A
Explanation
Choice A reason: Increasing dietary fiber is the cornerstone of nutritional management for diverticulosis. Fiber adds bulk to the stool, promotes regular bowel movements, and reduces intraluminal pressure in the colon, which helps prevent the formation and inflammation of diverticula.
Choice B reason: Increased sugar intake has no therapeutic benefit in diverticulosis and may contribute to poor overall dietary quality. It does not aid in bowel regulation or reduce diverticular complications.
Choice C reason: Protein intake is not directly related to diverticulosis management. While balanced nutrition is important, reducing protein does not affect diverticular disease progression or symptoms.
Choice D reason: Adequate water consumption is essential when increasing fiber intake to prevent constipation. Reducing water intake would counteract the benefits of fiber and increase the risk of bowel obstruction.
Correct Answer is C
Explanation
Choice A reason: Pain in the lower right quadrant is more commonly associated with appendicitis. While diverticula can occur throughout the colon, the sigmoid colon—located in the lower left quadrant—is most frequently affected.
Choice B reason: Upper right quadrant pain is typically linked to hepatobiliary conditions such as cholecystitis or hepatitis. It is not characteristic of diverticular disease.
Choice C reason: The lower left quadrant is the most common site of pain in diverticular disease, especially when the sigmoid colon is involved. Inflammation or infection of diverticula in this region leads to localized tenderness, cramping, and sometimes fever or changes in bowel habits.
Choice D reason: Upper left quadrant pain may be seen in conditions involving the spleen or stomach, such as splenic infarction or gastritis. It is not typical of diverticular disease.
