Correct Answer: B

Rationale: The correct answer is B: "Avoid foods that are high in fat." Clients with IBS should avoid foods high in fat as they can exacerbate symptoms such as abdominal pain, bloating, and diarrhea. High-fiber foods, choice A, can sometimes worsen symptoms in individuals with IBS. Increasing intake of dairy products, choice C, may also worsen symptoms for some individuals with IBS, especially if they are lactose intolerant. Drinking carbonated beverages, choice D, can contribute to bloating and gas, making symptoms worse for individuals with IBS.

Correct Answer: C

Rationale: Using an abduction pillow between the client's legs is essential in maintaining proper alignment and preventing dislocation of the hip joint following a hip arthroplasty. Encouraging the client to lie flat in bed (Choice A) is not recommended as early mobilization is crucial for preventing complications. Applying heat to the incision site (Choice B) is not typically done immediately postoperatively. Placing a trochanter roll under the client's knees (Choice D) is not as beneficial as using an abduction pillow to maintain proper positioning.

Correct Answer: C

Rationale: During a situation where a client is exhibiting violent behavior like throwing objects and posing a risk to themselves and others, the immediate priority is to ensure the safety of all involved. Placing the client in seclusion is a necessary intervention to prevent harm and allow for de-escalation. Asking the client to identify the trigger or instructing them to calm down may not be effective or safe in this escalated state. Encouraging the client to attend group therapy is not suitable when they are in an agitated and aggressive state that requires immediate intervention.

Correct Answer: A

Rationale: When mixing NPH and regular insulin in the same syringe, the nurse should first inject air into the NPH insulin vial. This action prevents contamination by allowing an easier withdrawal of the correct dose of NPH insulin after withdrawing the regular insulin. Withdrawing the prescribed dose of regular insulin (Choice B) is incorrect as it does not address the initial step of injecting air into the NPH vial. Similarly, withdrawing the prescribed dose of NPH insulin (Choice C) is incorrect as it skips the crucial first step. Mixing the two insulins in separate syringes (Choice D) is not ideal since combining them in one syringe is a common practice to reduce the number of injections for the patient.

Correct Answer: D

Rationale: Nonpitting ankle edema is a concerning sign of worsening preeclampsia due to fluid retention and should be reported immediately. Proteinuria of 1+ is a common finding in preeclampsia. A blood pressure of 120/80 mm Hg is within normal limits. A respiratory rate of 18/min is also within normal range. Therefore, choices A, B, and C are not as urgent as nonpitting ankle edema in this scenario.
