Difficulty: HardPharmacological Therapies

A practical nurse (PN) is preparing to administer scheduled morning medications, including oral pantoprazole and oral metoprolol, to a client admitted 24 hours24\text{ hours} ago with an upper gastrointestinal bleed. The client states, "My stomach hurts a little, but I am mostly just very dizzy." The client's current vital signs are: blood pressure 86/52 mm Hg86/52\text{ mm Hg}, heart rate 118 beats/min118\text{ beats/min}, respirations 22/min22\text{/min}, and oxygen saturation 96%96\% on room air. Based on this data, which action should the PN take first?

  1. Withhold the scheduled medications and immediately notify the registered nurse (RN) of the client's condition.Answer
  2. B
    Administer the pantoprazole to address the abdominal pain, but withhold the metoprolol due to the low blood pressure.
  3. C
    Administer both medications as prescribed and instruct the client to remain in a supine position to manage the dizziness.
  4. D
    Perform a comprehensive cardiovascular assessment to determine the cause of the vital sign changes before intervening.

Answer

The PN should withhold all scheduled medications and immediately notify the RN of the client's vital signs and symptoms.
The correct action is to withhold the medications and notify the RN. The client's hypotension, marked tachycardia, and dizziness 24 hours24\text{ hours} after a gastrointestinal bleed are classic indicators of active hemorrhage and hypovolemic shock. In this state, administering oral medications is unsafe due to decreased gastrointestinal perfusion and the risk of aspiration. Furthermore, a beta-blocker like metoprolol would suppress the client's compensatory tachycardia and dangerously lower the blood pressure further. The PN's scope of practice dictates the immediate escalation of these critical, unstable findings to the RN.

Step-by-Step Solution

1
Analyze the client's clinical data.
The client presents with significant hypotension (86/52 mm Hg86/52\text{ mm Hg}), marked tachycardia (118 beats/min118\text{ beats/min}), and dizziness.
Identifying abnormal assessment findings is the first step in determining safe medication administration.
2
Interpret the clinical significance of the findings in the context of the client's history.
These findings in a client with a recent gastrointestinal bleed strongly indicate active internal hemorrhage and hypovolemic shock.
Connecting current vital signs to the admitting diagnosis helps identify physiological instability.
3
Determine the pharmacological implications for the scheduled medications.
Administering metoprolol (a beta-blocker) would suppress the compensatory tachycardia and further lower blood pressure, worsening the shock. Administering any oral medication is contraindicated due to poor perfusion and potential need for emergency procedures.
Administering medications without considering physiological status can cause severe patient harm.
4
Apply the PN scope of practice to select the priority action.
The PN must withhold the medications and immediately escalate these critical findings to the RN for comprehensive evaluation and emergency intervention.
The PN role requires recognizing unstable conditions and communicating them promptly to the RN or provider.
