Zorluk: OrtaPharmacological Therapies

A practical nurse (PN) is providing care for a group of clients on a medical-surgical unit. Which of the following actions by the PN demonstrate safe pharmacological practice and appropriate adherence to the PN scope of practice? Select all that apply.

  1. Withholds a scheduled dose of oral potassium chloride and notifies the registered nurse (RN) after noting a morning serum potassium level of 5.9 mEq/L.Cevap
  2. Administers scheduled oral levothyroxine to a client on an empty stomach, 30 to 60 minutes before the breakfast tray arrives.Cevap
  3. Reinforces dietary teaching for a client prescribed oral warfarin by reviewing a list of foods high in vitamin K provided by the RN.Cevap
  4. D
    Prior to administering medications, verifies the identity of a confused client by asking a visiting family member because the client's wristband is missing.
  5. E
    Accepts a delegated task to initiate and titrate a continuous intravenous (IV) insulin infusion based on a sliding scale protocol.
  6. F
    Documents a client's acute onset of confusion following an initial dose of an opioid analgesic as an expected finding related to the normal aging process.

Cevap

The correct actions include withholding the potassium dose due to an elevated lab value and notifying the RN, administering levothyroxine on an empty stomach, and reinforcing established dietary teaching for warfarin.
Safe pharmacological practice within the PN scope involves verifying pertinent laboratory values before administration to prevent toxicity, ensuring the correct timing of medications like levothyroxine for maximum efficacy, and actively reinforcing educational plans previously established by the RN.

Adım Adım Çözüm

1
Evaluate each action against medication safety protocols and the practical nurse (PN) scope of practice.
Identified which actions reflect safe practices and which represent scope or safety violations.
Safe pharmacological therapy requires adherence to both correct administration techniques and legal scope limitations.
2
Identify correct medication administration practices.
Withholding potassium when levels are high (5.9 mEq/L) and giving levothyroxine on an empty stomach are correct pharmacological interventions.
These actions prevent dangerous drug toxicity and ensure optimal medication absorption.
3
Analyze delegation and teaching responsibilities.
Reinforcing an RN-developed teaching plan is within the PN scope. However, initiating and titrating IV insulin is beyond the PN scope.
PNs support the primary RN teaching plan but do not independently manage high-risk, titratable continuous IV infusions.
4
Assess client identification and adverse reaction monitoring protocols.
Asking a family member for patient ID is unsafe; confusion after opioid administration must be reported as a potential adverse effect, not normal aging.
Strict adherence to two independent patient identifiers is mandatory, and acute changes in mentation always indicate a need for further assessment for drug toxicity.

Anahtar Kavram

Safe medication administration and adherence to the Practical Nurse (PN) scope of practice, which includes monitoring for adverse effects, checking relevant lab values prior to administration, and reinforcing established client education.
