Correct Answer: C

Rationale: The correct answer is C: small intestine. This is because the small intestine is where the majority of nutrient absorption takes place due to its large surface area and presence of villi for absorption. The stomach (A) primarily functions in digestion, not absorption. The pancreas (B) produces digestive enzymes but does not directly absorb nutrients. The gallbladder (D) stores bile produced by the liver to aid in digestion but does not participate in absorption directly.

Correct Answer: A

Rationale: The correct answer is A: Neutropenia. Neutropenia is a common side effect of chemotherapy where there is a decrease in neutrophil count, increasing the risk of infections. Monitoring for neutropenia is crucial to prevent serious infections and sepsis in chemotherapy patients. Hyperkalemia (B), chronic pain (C), and hypertension (D) are not direct complications of chemotherapy and do not pose immediate life-threatening risks to patients undergoing chemotherapy. Monitoring for neutropenia takes precedence due to the potential for life-threatening infections in immunocompromised patients.

Correct Answer: C

Rationale: The correct answer is C: Monitor for transfusion reactions. When a client receiving a blood transfusion develops chills, it may indicate a transfusion reaction, such as a febrile non-hemolytic reaction. The nurse's first priority is to monitor the client closely for other signs of a reaction, such as fever, rash, or shortness of breath. Stopping the transfusion may be necessary, but monitoring for reactions is crucial to identify and manage any adverse effects promptly. Vital signs should be monitored as part of assessing for reactions. Performing a lumbar puncture is not indicated in this situation and is unrelated to managing a transfusion reaction.

Correct Answer: A

Rationale: The correct answer is A: Administer thrombolytics. Thrombolytics help dissolve blood clots causing the stroke, restoring blood flow to the brain. This intervention is time-sensitive to prevent further brain damage. Administering aspirin (B) is important but not the priority over thrombolytics. Performing an ECG (C) assesses heart function, not the immediate intervention for stroke. Administering corticosteroids (D) is not indicated in acute stroke management.

Correct Answer: A

Rationale: The correct answer is A: Body systems. This type of assessment promotes critical thinking by organizing data systematically based on different body systems, allowing for clustering of similar data and identification of patterns. Comprehensive assessments (B) may include body systems but lack the focused approach of promoting critical thinking. Head to toe assessments (C) are systematic but may not encourage clustering of data. Emergency assessments (D) prioritize immediate interventions rather than promoting critical thinking or clustering of data.
