Which of the following nursing intervention is appropriate to prevent pulmonary embolus in a patient who is prescribed bed rest?

Correct Answer: D

Rationale: Bed rest risks venous stasis, a pulmonary embolus cause. Leg movement promotes circulation, preventing clots from forming and traveling to lungs. Fluid limits dehydration but not emboli directly, deep breathing aids lungs but not veins, and knee gatch increases stasis. Nurses teach exercises, reducing thromboembolism risk, enhancing recovery safety.

Correct Answer: A

Rationale: Assessment's purpose is to establish a client database, collecting subjective (e.g., pain reports) and objective (e.g., blood pressure) data to understand health status comprehensively. This informs all nursing process steps diagnosis, planning, implementation, evaluation ensuring care is evidence-based. Delegating responsibility is a management task, not assessment's goal, which focuses on data, not task assignment. Teaching clients about health occurs later, using assessment findings, not defining its purpose. Implementing care follows planning, not assessment, which precedes action. By building a detailed picture e.g., a patient's asthma triggers assessment equips nurses to address needs accurately, making it the essential first step and primary purpose in delivering tailored, effective care.

Correct Answer: A

Rationale: Health promotion enhances well-being and prevents disease proactively administering immunizations (e.g., measles vaccine) exemplifies this, boosting immunity before illness strikes. Giving a bedbath is hygiene, not promotion supportive, not preventive. Preventing complications post-accident is tertiary prevention, managing existing issues, not promoting health preemptively. Diagnostic procedures (e.g., blood tests) detect, not promote assessment, not prevention. Immunizations align with health promotion's focus on empowering clients against disease, a core nursing role in public health, making this the standout example.

Correct Answer: B

Rationale: Axillary avoids the oral route post-surgery and is appropriate for a flushed, warm client.
