Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. The American Cancer Society recommends yearly mammograms after age 40 for early breast cancer detection. 2. Mammograms are most effective for women aged 40 and older in detecting breast cancer. 3. Regular mammograms can help detect breast cancer at an early stage, improving treatment outcomes. Summary of why other choices are incorrect: B: Mammograms should start at age 40, not after the birth of the first child. C: Mammograms are not recommended after the first menstrual period; they should start at age 40. D: Mammograms should be done annually after age 40, not every 3 years between ages 20 and 40.

Correct Answer: A

Rationale: The correct answer is A: Neutrophil. Neutrophils are the most numerous type of WBC, typically comprising 50-70% of total WBC count. They are key players in the body's immune response, phagocytizing pathogens. Basophils, eosinophils, and lymphocytes are less numerous than neutrophils. Basophils are involved in allergic reactions, eosinophils combat parasitic infections, and lymphocytes play a critical role in adaptive immunity. However, in terms of sheer numbers, neutrophils outnumber the other types of WBC.

Correct Answer: D

Rationale: The correct answer is D: Active listening. Active listening is crucial when working with a dying client and their family as it involves fully concentrating, understanding, responding, and remembering what is being said. This technique helps the nurse show empathy, build trust, and provide emotional support. By actively listening, the nurse can better understand the client's needs and concerns, which is essential in end-of-life care. Reflection (A) involves paraphrasing what the client said, which may not always be appropriate in this sensitive situation. Clarification (B) and Interpretation (C) involve adding one's own understanding or perspective, which can be intrusive and may not align with the client's feelings or beliefs.

Correct Answer: B

Rationale: The correct answer is B: Pallor. Pallor, which refers to paleness of the skin, is an early sign of anemia due to decreased red blood cell levels. Anemia causes reduced oxygen delivery to tissues, leading to paleness. Palpitations (A) may occur in anemia but are not an early sign. Glossitis (C) and weight loss (D) are not typically early signs of anemia and are more commonly associated with other health conditions.

Correct Answer: A

Rationale: The correct answer is A: Below 70mg/dl. Hypoglycemia is defined as a blood glucose level below 70mg/dl. Symptoms of hypoglycemia include confusion, shakiness, and sweating. Treating hypoglycemia involves administering fast-acting carbohydrates. Choices B, C, and D are incorrect because they describe blood glucose levels that are within the normal or hyperglycemic range, which are not indicative of hypoglycemia. It is essential for the nurse to recognize and promptly address hypoglycemia to prevent serious complications.
