Correct Answer: A

Rationale: The correct answer is A: Administering bronchodilators as prescribed. Rationale: 1. Bronchodilators help dilate the airways, improving airflow in COPD patients. 2. Priority is to address the underlying respiratory issue. 3. Bronchodilators are a standard treatment for managing COPD symptoms. 4. Improving airway patency is crucial in COPD exacerbations. Summary: - B: Encouraging avoidance of physical activity is incorrect as it can lead to deconditioning. - C: Providing supplemental oxygen is important but not the priority in this case. - D: Monitoring for acute kidney injury is unrelated to COPD management.

Correct Answer: C

Rationale: The correct answer is C: Neutropenia. Chemotherapy can suppress bone marrow function, leading to a decrease in neutrophils (a type of white blood cell), causing neutropenia. This increases the risk of infection. Monitoring for signs of infection is crucial in patients receiving chemotherapy to prevent serious complications. Anemia (A) is a common side effect of chemotherapy but is not directly related to infection risk. Hyperkalemia (B) and hypocalcemia (D) are less likely to be immediate complications of chemotherapy compared to neutropenia.

Correct Answer: D

Rationale: The correct answer is D because crossing arms and legs can indicate defensiveness or discomfort, which may suggest the parent is uneasy discussing their son's treatment. This nonverbal cue could signal a need for empathy and sensitivity in communication. Choice A is incorrect as it overlooks the significance of body language. Choice B assumes comfort without considering the context. Choice C assumes tiredness without considering other possibilities. Understanding body language cues can help in building rapport and addressing concerns effectively.

Correct Answer: A

Rationale: The correct answer is A: variable decelerations. Variable decelerations are abrupt decreases in fetal heart rate that vary in depth, duration, and timing, which can indicate cord compression. The variability in these decelerations suggests that the umbilical cord is being compressed intermittently. Early decelerations (B) are usually caused by head compression during contractions and mirror the contractions, not indicating cord compression. Bradycardia (C) is a slow heart rate, which can be caused by various factors but is not specific to cord compression. Tachycardia (D) is a fast heart rate, which can also be caused by various factors but is not typically associated with cord compression.

Correct Answer: A

Rationale: The correct answer is A: Psoriasis. Psoriasis is characterized by red, scaly patches on the skin, which align with the symptoms described. Psoriasis commonly affects the lower legs and is associated with severe itching. Eczema (choice B) is characterized by red, inflamed, and itchy skin patches, but typically presents differently from psoriasis. Contact dermatitis (choice C) is a localized reaction that occurs when the skin comes into contact with an irritant or allergen, and fungal infections (choice D) typically present with itching, redness, and sometimes peeling skin, but not necessarily scaly patches like psoriasis.
