Difficulty: MediumPharmacological and Parenteral Therapies

An emergency department nurse is managing the care of a client who presents with suspected septic shock secondary to pneumonia. Initial vital signs include a blood pressure of 88/54 mmHg, heart rate of 112 beats/min, respiratory rate of 22 breaths/min, and an oral temperature of 39.1 °C (102.4 °F). A peripheral intravenous (IV) line is currently infusing 0.9% sodium chloride. After reviewing the newly prescribed parenteral therapies, which of the following actions indicate safe pharmacological practice? Select all that apply.

  1. Initiate the prescribed secondary intravenous infusion of ceftriaxone through the existing 0.9% sodium chloride line.Answer
  2. Prepare to titrate a prescribed continuous intravenous infusion of norepinephrine if the client's mean arterial pressure remains below 65 mmHg after fluid resuscitation.Answer
  3. Assess the client's peripheral pulses and urine output frequently after initiating the prescribed continuous norepinephrine infusion.Answer
  4. D
    Administer a prescribed intravenous piggyback of levofloxacin through the primary IV line while a continuous heparin infusion is actively infusing via the same lumen.
  5. E
    Calculate the infusion pump rate for a prescribed weight-based vasopressor utilizing the client's self-reported weight from a recent clinic visit.
  6. F
    Postpone the administration of the prescribed intravenous antibiotics until the client's routine morning laboratory results are reported in the electronic health record.

Answer

The correct actions are to initiate the ceftriaxone through the compatible normal saline line, prepare to titrate norepinephrine for persistent hypotension, and closely assess peripheral pulses and urine output during the vasopressor infusion.
In the management of severe sepsis, early administration of intravenous antibiotics is a critical priority; ceftriaxone is physically compatible with 0.9% sodium chloride and can be safely administered through this existing line. If the client's hypotension does not resolve with fluid resuscitation, a vasopressor like norepinephrine is indicated to maintain a mean arterial pressure greater than 65 mmHg. Because norepinephrine causes profound vasoconstriction, the nurse must closely monitor markers of end-organ perfusion, such as urine output and peripheral pulses, to ensure tissue viability.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client is exhibiting signs of severe sepsis and septic shock, indicated by significant hypotension, tachycardia, and fever.
Identifying the client's physiological state determines the priority and appropriateness of nursing interventions.
2
Evaluate the safety and priority of the proposed parenteral therapies.
Antibiotics (ceftriaxone) are a top priority and are compatible with 0.9% sodium chloride. Norepinephrine is indicated for fluid-refractory hypotension and requires careful monitoring of tissue perfusion.
Safe pharmacological administration requires verifying compatibility, correct indications, and understanding necessary monitoring parameters.
3
Identify contraindicated and unsafe actions.
Delaying antibiotics, using historical weights for critical weight-based drips, and mixing incompatible drugs (levofloxacin and heparin) are identified as unsafe practices.
These actions directly compromise patient safety and violate medication administration standards.

Key Concept

Safe administration of parenteral therapies in severe sepsis requires immediate prioritization of antibiotics, strict verification of IV compatibility, use of accurate current weights for vasoactive infusions, and continuous monitoring of end-organ perfusion.
