One hour after arriving on the postoperative unit, a woman who received spinal anesthesia 5 hours ago is complaining of severe abdominal incisional pain. Her vital signs are: temperature 99° F (37.2° C), heart rate 110 beats/minute, respiratory rate 30 breaths/minute and blood pressure 160/90 mmHg. The client's skin is pale, and the surgical dressing is dry and Intact. Which intervention is most important for the nurse to Implement?
Provide pillow for splinting.
Assess the IV site for patency.
Place in a high Fowler position.
Administer an IV analgesic.
None
None
The Correct Answer is D
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

Correct Answer is D
Explanation
A. A 12-year-old reporting neck, arm, and lower back discomfort:
- This child is reporting discomfort, which is concerning, but it doesn't indicate an immediate life-threatening condition. However, a thorough assessment is needed to rule out any serious injuries, especially to the spine.
B. An 8-year-old with a full leg air splint for a possible broken tibia:
- While a possible broken tibia requires attention, it is not as immediately critical as symptoms such as projectile vomiting. Splinting can help stabilize the limb, but it is not an emergency that requires immediate attention compared to potential neurological issues.
C. A 6-year-old with multiple superficial lacerations of all extremities:
- Superficial lacerations, although they require care, are generally not immediately life-threatening. The child needs appropriate wound care and assessment for any deeper injuries, but this can be addressed in a timely manner without immediate urgency.
D. An 11-year-old with a headache, nausea, and projectile vomiting:
- This is the most concerning presentation among the options. Headache, nausea, and projectile vomiting could be indicative of a severe head injury, and these neurological symptoms require urgent evaluation to assess for conditions such as a concussion, intracranial bleed, or increased intracranial pressure.
Correct Answer is A
Explanation
An S3 heart sound can be a normal finding during pregnancy due to increased blood volume and changes in cardiac output. It is known as a physiological S3 and is considered a benign finding in the absence of other concerning symptoms or signs.
In this case, there is no immediate need for intervention or concern regarding the S3 heart sound. It is not necessary to prepare the client for an echocardiogram or limit the client's fluids based solely on the presence of an S3 heart sound in the absence of other significant symptoms or complications.
