The registered nurse (RN) staff nurse observes a licensed practical nurse (LPN) crushing nifedipine XL before administering the medication to a client diagnosed with arterial hypertension who has difficulty swallowing pills. Which intervention should the RN implement first?
Take no action because this is appropriate behavior.
Tell the LPN to take the client's blood pressure.
Tell the LPN this medication cannot be crushed.
Show the LPN where to find pudding for the client.
The Correct Answer is C
Extended-release formulations utilize a specialized matrix to ensure the steady physiological release of a drug over a 24-hour period. Crushing these medications causes dose dumping, where the total therapeutic concentration is released simultaneously into the systemic circulation. This rapid absorption triggers profound hypotension and reflex tachycardia, potentially leading to myocardial ischemia or cerebrovascular collapse.
Rationale:
A. Taking no action is a violation of safety standards and constitutes clinical negligence by the supervising nurse. Crushing a long-acting calcium channel blocker is a medication error that places the client at risk for severe adverse events. The RN must intervene immediately to ensure client safety and prevent the administration of a compromised dose.
B. Assessing the blood pressure is an important follow-up step if a medication has already been administered improperly. However, the first priority is preventing administration before the error occurs to avoid a pharmacological emergency. Immediate verbal correction of the unsafe practice is the primary nursing intervention required to protect the patient.
C. This is the priority action because nifedipine XL is a sustained-release medication that must remain intact to function safely. Crushing the pill destroys the delivery mechanism, leading to a lethal dose of medication being absorbed at once. The RN has a professional responsibility to halt an incorrect procedure and provide immediate education to the LPN.
D. Providing pudding or other soft foods is a common strategy for assisting clients with oropharyngeal dysphagia who have difficulty swallowing medications. However, adding pudding does not change the fact that this specific drug is strictly contraindicated for crushing or alteration. The nurse must instead request a liquid formulation or an immediate-release alternative from the healthcare provider.

Correct Answer is C
Explanation
Disaster triage and management involve the rapid allocation of resources to maximize survival during a mass casualty event. This process requires surge capacity planning and the immediate identification of stable clients for expedited discharge to create bed availability for incoming critically injured victims requiring acute stabilization.
Rationale:
A. Stocking additional supplies is a logistical task that should be handled by the central supply or materials management department. The charge nurse must maintain focus on clinical leadership and the flow of patient admissions rather than performing manual inventory tasks during the initial protocol phase.
B. While discharge education is necessary, reinforcing teaching is a time-consuming process that should occur after identifying eligible clients. The initial phase of a disaster protocol requires rapid assessment of the unit census to determine who can safely leave the hospital immediately.
C. The priority action for the charge nurse is to facilitate bed availability through safe discharge. Identifying clients who are hemodynamically stable allows the facility to expand its surge capacity, ensuring that medical-surgical beds are available for disaster victims who require immediate inpatient monitoring.
D. Redirecting assistive personnel to focus on activities of daily living is inappropriate during a mass casualty event. Non-essential tasks should be suspended, and personnel should be reassigned to assist with emergency procedures, patient transport, or setting up for incoming disaster-related admissions.
Correct Answer is ["C","D"]
Explanation
Effective delegation requires clinical judgment to differentiate between stable and unstable outcomes. Unlicensed personnel perform non-complex tasks involving functional activities or routine data collection. The nurse remains legally accountable for assessing patients, interpreting vital signs, and performing any invasive clinical interventions.
Rationale:
A. Postoperative patients require advanced assessment by the registered nurse during their first mobilization. Initial ambulation carries risks of orthostatic hypotension or prosthesis dislocation. The nurse must evaluate the patient's balance, weight-bearing tolerance, and neurological status before delegating subsequent walks to assistive personnel.
B. The process of discharge teaching involves complex pedagogical strategies and evaluation of learner readiness. Only the licensed nurse can provide education or clarify medical instructions. UAPs can assist with packing personal belongings but cannot explain medications, follow-up care, or signs of complications.
C. Collecting physiological data for a patient in a stable condition is a standard UAP competency. While the patient receives medication, the measurement of blood pressure and heart rate is a repetitive, objective task. The nurse must still interpret these values for potential adverse reactions.
D. Patients who are 48 hours post-hysterectomy are typically considered physiologically stable for routine activity. Assisting a recovering patient with mobility is within the UAP scope of practice once the initial assessment is complete. This helps prevent venous thromboembolism and promotes bowel motility.
E. Inserting peripheral venous catheters is an invasive procedure requiring sterile technique and clinical expertise. Such tasks are strictly outside the scope of unlicensed personnel. The nurse must perform the venipuncture and then assess the patient's response to any administered analgesic medications.
