Correct Answer: A

Rationale: In this scenario, the highest priority nursing problem for the postoperative client following a ureterolithotomy via a flank incision is ineffective airway clearance. After surgery, there is a risk of airway obstruction due to factors like anesthesia, positioning during surgery, or the presence of secretions. Maintaining a clear airway is crucial to prevent respiratory complications, such as atelectasis or pneumonia. Altered nutrition, fluid volume excess, and activity intolerance are important considerations but are secondary to the immediate threat of compromised airway clearance in the postoperative period.

Correct Answer: D

Rationale: The correct answer is D. Bruised areas on the client's upper extremities bilaterally indicate an increased risk of bleeding, which requires careful assessment before administering enoxaparin. Bruising suggests potential issues with clotting and hemostasis, making it crucial for the nurse to further evaluate the client's bleeding risk. Choices A, B, and C do not directly relate to the assessment of bleeding risk associated with enoxaparin administration and are therefore incorrect. Choice A provides information about the client's Aptt, which is not directly relevant to assessing bleeding risk for enoxaparin. Choice B addresses pain management, and Choice C involves the client's daily activities with no direct link to the bleeding risk assessment.

Correct Answer: A

Rationale: The correct action for the nurse to implement when caring for a client with a radioactive Cesium-loaded vaginal applicator during brachytherapy is to wear a dosimeter film badge when in the client's room. Wearing a dosimeter badge is essential to monitor radiation exposure and ensure the safety of healthcare providers. Choice B is incorrect as the duration is not specified and unnecessary. Choice C is incorrect as changing linens daily does not directly relate to radiation safety. Choice D is incorrect as using gloves to remove the applicator if dislodged is important but not the primary action to monitor radiation exposure.

Correct Answer: D

Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.

Correct Answer: B

Rationale: The correct answer is B. Each child has a 25% chance of having sickle cell anemia if both parents are carriers of the trait. Choice A is incorrect because not all future children will be carriers; some may have the disease. Choice C is incorrect as both male and female children can inherit the sickle cell disease trait. Choice D is incorrect as the chance is not fixed at one out of four; each child has an independent 25% chance of having the disease.
