Correct Answer: C

Rationale: Peripheral edema in a client with cirrhosis can indicate fluid overload and worsening liver function, necessitating immediate intervention to prevent further complications such as respiratory distress, cardiac issues, or renal impairment. Jaundice (choice A) is a common manifestation of cirrhosis but may not require immediate intervention unless severe. Ascites (choice B) is also a common complication of cirrhosis that may require intervention but is not as urgent as addressing peripheral edema. Spider angiomas (choice D) are typically benign skin lesions associated with cirrhosis but do not require immediate intervention unless bleeding or rupture occurs.

Correct Answer: D

Rationale: The correct answer is D because participating in contact sports can increase the risk of injury and bleeding in a client receiving warfarin therapy. Warfarin is a blood thinner, and activities with a higher risk of injury should be avoided to prevent bleeding complications. Choices A, B, and C are all correct statements for a client on warfarin therapy. Avoiding foods high in vitamin K helps maintain consistent anticoagulation levels, using a soft toothbrush and an electric razor reduces the risk of bleeding gums and cuts, and keeping appointments for blood tests ensures proper monitoring of the client's international normalized ratio (INR) levels.

Correct Answer: A

Rationale: Option A is the correct answer because understanding the percentage of the population under 19 years of age in each of the previous five years helps to determine if the high percentage of youth is a consistent trend or a recent change. This information is crucial for assessing the need for a new well-child clinic. Choices B, C, and D are incorrect because they do not directly address the gaps in the data related to the age distribution trend over time, which is essential for making an informed decision about the necessity of the proposed clinic.

Correct Answer: A

Rationale: The correct answer is early adolescent girls. Scoliosis is most commonly diagnosed during early adolescence, with girls being more affected than boys. Including early adolescent girls in the screening clinic aligns with the age group that is at higher risk for scoliosis. Late adolescent boys (choice B) are less likely to develop scoliosis compared to early adolescent girls. 7-10 year old boys (choice C) are typically younger than the age group where scoliosis is commonly diagnosed. Preschoolers of both genders (choice D) are too young for scoliosis screening as the condition usually manifests during adolescence.

Correct Answer: C

Rationale: Verifying the blood type and Rh factor with another healthcare professional is the most crucial action to prevent a transfusion reaction. Ensuring compatibility between the donor blood and the recipient is essential in preventing adverse reactions such as hemolytic transfusion reactions. Checking vital signs is important for monitoring the client during the transfusion process but does not directly prevent a transfusion reaction. Using a blood filter can help remove clots and debris but does not address the risk of a reaction due to blood type incompatibility. Administering antihistamines before the transfusion is not a standard practice to prevent transfusion reactions related to blood type incompatibility.
