Which method of data collection will the nurse use to establish a patient’s database?

Correct Answer: C

Rationale: The correct answer is C because performing a physical examination is the method nurses use to establish a patient's database. This involves directly assessing the patient's physical condition, gathering data on their health status, and identifying any abnormalities or concerns. Reviewing literature (A) is important but not a direct method of collecting patient data. Checking orders for tests (B) is part of data collection but not the initial step. Ordering medications (D) is a treatment action, not data collection.

Correct Answer: C

Rationale: The correct answer is C: Diagnostic reasoning. Diagnostic reasoning involves using assessment data and critical thinking skills to develop a nursing diagnosis. This process includes analyzing and interpreting data to make clinical judgments about the patient's health status. A: Assigning clinical cues is incorrect because this refers to identifying and documenting specific observations or findings during the assessment process, not the process of developing a nursing diagnosis. B: Defining characteristics is incorrect because this refers to the specific symptoms or manifestations used to support a nursing diagnosis, not the overall process of diagnostic reasoning. D: Diagnostic labeling is incorrect because this refers to assigning a formal name to the nursing diagnosis, not the process of critically analyzing assessment data to develop it.

Correct Answer: D

Rationale: The correct answer is D: Leucovorin. Leucovorin is given during methotrexate therapy to protect normal cells by acting as a rescue agent that helps to reduce the toxic effects of methotrexate. It works by enhancing the efficacy of methotrexate in cancer cells while reducing its toxicity in normal cells. Probenecid (A) is not used to protect normal cells during methotrexate therapy. Cytarabine (B) and Thioguanine (C) are other chemotherapeutic agents and are not typically given to protect normal cells during methotrexate therapy.

Correct Answer: B

Rationale: The correct answer is B: Maintain strict aseptic technique. This is crucial during thoracentesis to prevent infection. Step 1: Before the procedure, sterile equipment and supplies must be used. Step 2: Proper hand hygiene is essential to reduce the risk of introducing pathogens. Step 3: During the procedure, maintaining a sterile field helps minimize the risk of contamination. Step 4: After the procedure, ensuring proper disposal of all used supplies prevents the spread of infection. Summary: A: Placing the patient in a quiet and cool room may be comforting but is not directly related to the safety of the procedure. C: Advising the patient to sit still is important for accurate needle insertion but does not address infection prevention. D: Applying pressure over the puncture site is important but does not prevent infection if aseptic technique is not maintained.

Correct Answer: A

Rationale: The correct answer is A. 1. Change in level of consciousness is crucial in assessing neurological status. 2. Tachypnea indicates possible respiratory distress or oxygenation issues. 3. Tachycardia may suggest a cardiovascular problem or inadequate perfusion. 4. Petechiae can be a sign of bleeding disorders or sepsis. Option B is incorrect because chest pain, diaphoresis, and nausea/vomiting are more indicative of a cardiac event rather than monitoring for J.E.'s signs and symptoms. Option C is incorrect because loss of consciousness, bradycardia, and leg pain do not align with the signs and symptoms to monitor for J.E. Option D is incorrect because bradycardia, chest pain, and oliguria are not as comprehensive as the signs and symptoms listed in option A for monitoring J.E.
