Correct Answer: A

Rationale: The correct answer is A: Completes a comprehensive database. In the first phase of the nursing process (assessment), the nurse collects data to form a comprehensive database about the patient's health status. This step is crucial as it provides the foundation for identifying nursing diagnoses, planning interventions, and evaluating outcomes. Identifying nursing diagnoses (B) occurs in the second phase (diagnosis), intervening based on priorities of patient care (C) is part of the third phase (planning), and determining whether outcomes have been achieved (D) is in the fourth phase (evaluation). Completing a comprehensive database in the first phase ensures a thorough understanding of the patient's needs before proceeding to the next steps in the nursing process.

Correct Answer: A

Rationale: The correct answer is A: Completes a comprehensive database. During the first phase of the nursing process (assessment), the nurse collects data to establish a comprehensive database of the patient's health status. This information serves as the foundation for identifying nursing diagnoses, planning interventions, and evaluating outcomes. Identifying nursing diagnoses (B) occurs in the second phase (diagnosis), intervening based on priorities (C) in the third phase (planning), and determining outcomes achieved (D) in the fourth phase (evaluation). Completing a comprehensive database is crucial in the initial assessment phase to gather accurate information for the subsequent steps in the nursing process.

Correct Answer: C

Rationale: Rationale: 1. Anemia results in decreased oxygen-carrying capacity, leading to tissue hypoxia. 2. Dyspnea (shortness of breath) occurs due to the body's attempt to increase oxygen intake. 3. Tachycardia (rapid heart rate) compensates for decreased oxygen delivery. 4. Pallor (pale skin) is a classic sign of decreased red blood cells in iron-deficiency anemia. Summary: A: Night sweats, weight loss, and diarrhea are not typical manifestations of iron-deficiency anemia. B: Nausea, vomiting, and anorexia are non-specific symptoms and not specific to iron-deficiency anemia. D: Itching, rash, and jaundice are not commonly associated with iron-deficiency anemia.

Correct Answer: C

Rationale: The correct answer is C because jaundice is a common manifestation of sickle cell anemia due to the breakdown of red blood cells. The nurse should inspect the skin and sclera for the characteristic yellow discoloration indicating jaundice. This assessment is specific to identifying jaundice, which is directly related to the disease process. Choice A is incorrect as it relates to assessing neurological function, not jaundice. Choice B is incorrect as joint swelling is not a typical sign of jaundice in sickle cell anemia. Choice D is incorrect as a urine specimen is not used to assess jaundice; skin and sclera inspection are more appropriate.

Correct Answer: B

Rationale: The correct answer is B: a semi-private room. For a burn patient like Mr. Boy, a semi-private room is preferred to provide a more controlled environment for infection prevention, wound care, and privacy. Strict isolation (A) is not necessary as his burns are not infectious. Liberal visiting (C) can increase the risk of infection and compromise his recovery. Sharing equipment (D) can lead to cross-contamination and is not recommended for burn patients. In summary, a semi-private room balances infection control and patient comfort for burn patients.
