Correct Answer: C

Rationale: The correct answer is C: Severity. In the PQRSTU mnemonic, "S" stands for Severity, which refers to the intensity or seriousness of the symptoms experienced by the patient. This is crucial in assessing the impact of the problem on the patient's health and well-being. Incorrect choices: A: Swelling - Swelling is a physical symptom and does not encompass all aspects of the patient's perception. B: Subjectivity - While the patient's subjective experience is important, it does not specifically refer to severity. D: Symptoms - While symptoms are part of the patient's perception, the "S" in PQRSTU specifically focuses on the severity of those symptoms.

Correct Answer: D

Rationale: The correct answer is D: Assessment. Assessment is the first step in the nursing process where data is collected through health history, physical examination, and interview. This step helps in identifying the patient's needs and health problems. Planning (A) comes after assessment and involves setting goals and creating a care plan. Diagnosis (B) is the step where nursing diagnoses are formulated based on the assessment data. Evaluation (C) is the final step where the effectiveness of the care plan is assessed. In summary, Assessment is the initial step focused on data collection, making it the correct choice.

Correct Answer: B

Rationale: Correct Answer: B (Administer nonsteroidal anti-inflammatory drugs - NSAIDs) Rationale: 1. NSAIDs are commonly used for chronic pain management due to their anti-inflammatory properties. 2. NSAIDs target the underlying inflammation that often contributes to chronic pain. 3. Opioids may be reserved for severe pain due to their potential for addiction and side effects. 4. Monitoring blood pressure is important but not the primary intervention for chronic pain. 5. Acetaminophen is a mild pain reliever and may not be as effective for chronic pain compared to NSAIDs.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. The initial priority in managing sepsis is to restore perfusion and oxygenation by giving IV fluids to support blood pressure and organ perfusion. This helps to improve tissue oxygenation and prevents further organ damage. Administering insulin (choice B) is not the priority in the initial management of sepsis. Monitoring blood pressure (choice C) is important but not the first step in the management of sepsis. Administering insulin is also listed twice and is not relevant to the immediate management of sepsis.

Correct Answer: D

Rationale: I must correct you on this question. The correct answer for the most appropriate action for a nurse to take when a client develops a deep vein thrombosis (DVT) is not D. The correct answer should be C: Provide anticoagulant therapy. Anticoagulant therapy is the standard treatment for DVT to prevent the blood clot from getting larger and to reduce the risk of it breaking loose and causing a pulmonary embolism. Elevating the leg and applying compression can help with symptoms but are not the primary treatment for DVT. Massage is contraindicated as it can dislodge the blood clot.
