Review H and P and nurse's notes.

What are the first four actions that the nurse should take?

A) Incorrect- Standard precautions are used for all clients to prevent the spread of infections.
However, in the case of MRSA, contact precautions are needed due to the risk of direct transmission through physical contact.
B) Correct- Monitoring the white blood cell count is important to assess for signs of infection, as an elevated count might indicate an ongoing inflammatory response.
C) Correct- Foul-smelling drainage from an incision with suspected MRSA indicates a potential infection. Contact precautions are appropriate for MRSA, which include wearing gloves and gowns when entering the client's room to prevent the spread of the bacteria.
D) Correct- Sending wound drainage for culture and sensitivity helps identify the specific microorganisms causing the infection and guides appropriate antibiotic treatment.
E) Incorrect- A low-bacteria diet is not relevant to the situation. MRSA is caused by a bacterium, not by dietary factors. The focus should be on infection control measures and appropriate medical interventions.

The correct answer is Choice D

Choice A rationale: Splinting with a pillow may reduce discomfort during movement or coughing by stabilizing the incision site, but it does not address acute postoperative pain with sympathetic overdrive. The elevated heart rate, respiratory rate, and blood pressure suggest a stress response mediated by catecholamines. Without analgesia, nociceptive signals continue to activate the hypothalamic-pituitary-adrenal axis. While splinting is supportive, it lacks the pharmacologic efficacy needed to blunt nociceptive transmission at the spinal or supraspinal level.

Choice B rationale: Assessing IV patency is a procedural prerequisite for medication administration but not a therapeutic intervention in itself. It does not directly address the pathophysiology of acute pain or the sympathetic surge evidenced by tachycardia and hypertension. Pain activates ascending pathways via A-delta and C fibers, requiring pharmacologic blockade. IV access assessment is necessary but secondary to the urgent need for analgesia to prevent complications like hypoxia, hyperventilation, or delayed recovery.

Choice C rationale: High Fowler positioning may improve diaphragmatic excursion and reduce pulmonary complications, but it does not mitigate visceral or incisional pain. In fact, increased intra-abdominal pressure from upright posture may exacerbate pain at the surgical site. Pain perception involves central sensitization and peripheral nociceptor activation, which are unaffected by positioning. The client’s pale skin and elevated vitals indicate systemic distress requiring analgesic intervention, not postural adjustment. Thus, this choice lacks direct analgesic benefit.

Choice D rationale: IV analgesics act rapidly to inhibit nociceptive transmission at the spinal cord and brainstem levels. Opioids bind to mu receptors, reducing neurotransmitter release and hyperpolarizing neurons, thereby dampening pain signals. This intervention directly targets the physiologic cause of elevated heart rate, respiratory rate, and blood pressure. Normal heart rate is 60–100 bpm, respiratory rate 12–20 breaths/min, and BP <120/80 mmHg. Prompt analgesia prevents complications like hypoxia, delayed healing, and neuroendocrine stress
