A nurse is collecting data from a child who is 1 hr postoperative following a tonsillectomy. Which of the following findings is the nurse's priority?

A. Oxygen saturation 95%: An oxygen saturation of 95% is within normal limits for most clients and does not indicate respiratory compromise. No immediate provider notification is necessary based solely on this oxygen saturation level during opioid therapy.

B. Respiratory rate 14/min: A respiratory rate of 14 breaths per minute is normal. Significant respiratory depression from opioids like hydromorphone would typically be indicated by a rate lower than 12 breaths per minute.

C. Urinary output 160 mL/8 hr: Urinary output should be at least 30 mL/hr. A total of 160 mL in 8 hours is significantly low, suggesting possible urinary retention or decreased renal perfusion, both of which can be side effects of opioid use and should be reported promptly.

D. Blood pressure 108/58 mm Hg: While this blood pressure is on the lower side, it is not critically low for many adults. Unless the client is symptomatic with dizziness or fainting, this blood pressure alone does not require immediate provider notification.

A. Anorexia: Anorexia, or loss of appetite, is not a typical adverse effect directly associated with heparin use. While it may occur due to general postoperative factors, it is not an urgent or life-threatening reaction that necessitates immediate reporting related to anticoagulant therapy.

B. Epistaxis: Epistaxis, or nosebleed, is a sign of potential bleeding complications, which is a major adverse effect of heparin. Because heparin inhibits clot formation, any evidence of spontaneous bleeding must be reported immediately to the provider to assess for potential heparin-induced bleeding disorders.

C. Weight gain: Weight gain could suggest fluid retention, but it is not a typical adverse effect of heparin. While postoperative clients should be monitored for signs of fluid imbalance, sudden bleeding signs like epistaxis are far more critical to recognize and report when administering anticoagulants.

D. Bradycardia: Bradycardia, or slow heart rate, is not commonly linked to heparin therapy. While abnormal heart rhythms may occur postoperatively for other reasons, they are not typically associated with bleeding risks from heparin and thus do not require urgent reporting specific to heparin use.
