A nurse is planning to obtain a 12-lead ECG for a client who has a history of cardiac dysrhythmias. Which of the following actions should the nurse plan to take?

This question focuses on identifying manifestations of opioid-induced respiratory depression following IV morphine administration. Morphine is an opioid analgesic that depresses the central nervous system and can suppress the respiratory drive, especially in postoperative clients who are already sedated from anesthesia. Findings such as somnolence, pinpoint pupils, bradypnea, hypotension, and decreased respiratory effort are classic indicators of opioid toxicity. Early recognition is critical because progressive respiratory depression can rapidly lead to hypoxia, respiratory arrest, and cardiovascular collapse.

Rationale for Correct findings:

• Decreased respiratory effort, bilateral crackles: Decreased respiratory effort following morphine administration is a serious sign of opioid-induced respiratory depression. Opioids suppress the medullary respiratory center, leading to slower and shallower breathing that reduces oxygen exchange. Bilateral crackles may indicate retained secretions, atelectasis, or developing pulmonary complications due to hypoventilation. This finding requires immediate nursing intervention, including respiratory assessment, oxygen support, and possible naloxone administration.

• Somnolent: Excessive somnolence is an early neurologic indicator of opioid oversedation and can precede respiratory arrest. A client who becomes increasingly difficult to arouse may not maintain adequate airway protection or respiratory effort. Monitoring the level of consciousness is essential because declining neurologic responsiveness correlates closely with worsening respiratory depression. Immediate reassessment and provider notification are warranted.

• Pinpoint pupils: Pinpoint pupils, or miosis, are a classic manifestation of opioid effects on the central nervous system. In the postoperative setting, this finding strongly suggests excessive opioid activity, particularly when accompanied by sedation and bradypnea. Although miosis alone may not be dangerous, it becomes clinically significant when occurring alongside respiratory depression. This finding helps confirm suspected opioid toxicity and requires prompt evaluation.

• Respiratory rate 10/min: A respiratory rate of 10/min is abnormally low and indicates bradypnea, which is a major concern after opioid administration. Respiratory depression is one of the most dangerous adverse effects of morphine because inadequate ventilation can lead to carbon dioxide retention and hypoxemia. A declining respiratory rate often precedes respiratory arrest if untreated. Immediate assessment and intervention are necessary to prevent deterioration.

• Blood pressure 98/58 mm Hg: Hypotension can occur with morphine because opioids cause peripheral vasodilation and reduce sympathetic nervous system activity. The client’s blood pressure has dropped significantly from baseline, suggesting a clinically important hemodynamic effect. Combined with sedation and respiratory depression, hypotension may indicate worsening opioid toxicity. Reduced perfusion can compromise oxygen delivery to vital organs and requires urgent monitoring and management.

Rationale for incorrect findings:

• S1, S2, no murmur, bradycardia: A heart rate of 58/min represents mild bradycardia, which can occur postoperatively or secondary to opioid administration. While it should continue to be monitored, it is less immediately dangerous than respiratory depression or altered consciousness. The absence of murmurs or abnormal heart sounds suggests no acute structural cardiac complication.

• Temperature 37.4° C (99.4° F): A temperature of 37.4°C is within a mild postoperative range and does not indicate acute infection or severe systemic complication. Slight elevations in temperature can occur after surgery because of inflammation or stress response. Compared with the client’s respiratory and neurologic changes, this finding is not immediately life-threatening. Ongoing monitoring is appropriate, but urgent intervention is not required based on temperature alone.

• Heart rate 58/min: Although slightly below normal, a heart rate of 58/min is not as critical as the client’s low respiratory rate and decreased responsiveness. Mild bradycardia may occur due to opioid effects, vagal stimulation, or postoperative relaxation. Since perfusion is still being maintained and no dysrhythmias are described, it is a secondary concern at this time. Airway and breathing abnormalities take priority over circulation in this scenario.

Assessment of a client with Acute cholecystitis focuses on identifying characteristic biliary pain patterns and associated gastrointestinal symptoms. This condition typically results from obstruction of the cystic duct by gallstones, leading to inflammation, gallbladder distention, and localized peritoneal irritation. Pain patterns are important diagnostic indicators and help differentiate biliary disease from cardiac, urinary, or gastric causes of abdominal discomfort.

Rationale:
A. Pain radiating to the jaw is more commonly associated with cardiac conditions such as myocardial ischemia. Gallbladder inflammation typically does not produce referred pain to the jaw. Instead, biliary pain is usually localized to the right upper quadrant or may radiate to the right shoulder or scapula.

B. Right upper abdominal pain is the classic presentation of Acute cholecystitis due to gallbladder inflammation and obstruction. The pain is often severe, steady, and may worsen after fatty meals. It results from distension and inflammation of the gallbladder wall.

C. Increased abdominal discomfort prior to meals is more characteristic of peptic ulcer disease or gastric disorders rather than gallbladder inflammation. Cholecystitis pain is typically triggered or worsened after eating, especially fatty foods, rather than before meals.

D. Discomfort with urination is associated with urinary tract infections or renal pathology, not gallbladder disease. Acute cholecystitis does not involve the urinary system, so urinary symptoms would suggest a different underlying condition.
