Correct Answer: A

Rationale: The correct answer is A because in the four-point gait with partial weight bearing, the client should move the right crutch ahead first to provide support and stability, followed by the left foot. This sequence ensures proper weight distribution and balance. Moving both crutches together (B) may compromise stability. Moving the left crutch and right foot together (C) may cause uneven weight distribution. Moving both crutches and weaker leg together (D) may not provide adequate support for the weaker leg.

Correct Answer: B

Rationale: The correct answer is B: Have a mammogram annually. Mammograms are recommended by the American Cancer Society for breast cancer screening in women as they are effective in detecting early signs of breast cancer. Mammograms have been shown to reduce mortality rates from breast cancer. Annual mammograms are crucial for early detection and treatment. A: Performing breast self-examination annually is not recommended as a standalone screening method as it has not been shown to significantly reduce mortality rates. C: Having a normal receptor assay annually is not a standard screening test for breast cancer recommended by the American Cancer Society. D: Having a physician conduct a clinical examination every 2 years is not as effective as annual mammograms for detecting early signs of breast cancer.

Correct Answer: B

Rationale: The correct answer is B: Ulcerative colitis. Iron therapy can exacerbate gastrointestinal issues, including ulcerative colitis due to its potential to cause irritation and inflammation in the digestive tract. This can lead to worsening symptoms and complications for the client. A: Pregnancy is not a contraindication for iron therapy; in fact, it is commonly prescribed during pregnancy to prevent or treat anemia. C: Asthma is not a contraindication for iron therapy as it does not directly interact with asthma or its treatment. D: Severely impaired liver function is not a direct contraindication for iron therapy, although caution may be needed in such cases due to iron metabolism being affected by liver function.

Correct Answer: B

Rationale: The correct answer is B: Administering platelets, as ordered to maintain an adequate platelet count. In ITP, the client has low platelet count leading to risk of bleeding. Administering platelets helps raise platelet levels and prevent bleeding complications. Teaching coughing and deep-breathing techniques (A) is important for preventing respiratory infections but not directly related to ITP. Giving aspirin (C) is contraindicated as it can further decrease platelet count. Administering stool softeners (D) is important for preventing straining but not specific to managing ITP.

Correct Answer: C

Rationale: The correct answer is C: chronic biliary inflammation or obstruction. Biliary cirrhosis is a condition characterized by scarring of the liver due to long-term damage to the bile ducts. Chronic biliary inflammation or obstruction can lead to the build-up of bile in the liver, causing damage over time. Acute viral hepatitis (choice A) typically does not directly cause biliary cirrhosis. Alcohol hepatotoxicity (choice B) is more commonly associated with alcoholic liver disease rather than biliary cirrhosis. Hepatic failure with prolonged venous hepatic congestion (choice D) may lead to liver cirrhosis, but it is not specific to biliary cirrhosis.
