LPN Fundamentals Practice Test Questions
Question 1 of 5
The nurse is planning to suction a client through a tracheostomy tube. Which is the amount of time for application of suction during withdrawal of the catheter?
Correct Answer: A
Rationale: Suctioning through a tracheostomy should last 10 seconds (A) during withdrawal to minimize hypoxia and trauma, per standard guidelines. Longer times 25 (B), 30 (C), or 35 (D) seconds increase risks of oxygen depletion and mucosal injury. A is correct. Rationale: Limiting suction to 10 seconds balances secretion removal with oxygenation preservation, a key safety measure in airway management, preventing complications like atelectasis or arrhythmias, as endorsed by AACN and ATS.
Question 2 of 5
When caring for a client with a head injury that may have involved the medulla, the nurse bases assessments on the knowledge that the medulla controls a variety of functions. Which functions will the nurse assess? Select all that apply.
Correct Answer: C
Rationale: The medulla controls vital functions like pulse rate (C), breathing (B), and swallowing. Balance (A) is cerebellar. Temperature regulation (D) is hypothalamic. C is correct for CSV. Rationale: Medulla injury disrupts cardiac rhythm, a critical assessment in head trauma, per neuroanatomy, as it houses the vagus nerve and cardiovascular centers, unlike other regions controlling non-vital functions.
Question 3 of 5
Which color tag will be given by the triage nurse to a client assigned to class IV, during a mass casualty situation?
Correct Answer: B
Rationale: Class IV in mass casualty triage (black tag, B) indicates expectant/deceased, unlikely to survive. Red (A) is immediate. Green (C) is minor. Yellow (D) is delayed. B is correct. Rationale: Black tags prioritize resources for salvageable patients, a standard in disaster triage, per START protocol.
Question 4 of 5
The nurse is caring for a client with a spinal cord injury who is at risk for deep vein thrombosis (DVT). Which intervention should the nurse implement?
Correct Answer: A
Rationale: Sequential compression devices (A) prevent DVT in immobile SCI patients. Active exercise (B) isn't feasible. Anticoagulants (C) need orders. Massage (D) risks emboli. A is correct. Rationale: Compression enhances venous return, reducing stasis, per DVT prophylaxis in SCI, a standard intervention.
Question 5 of 5
Which of the following reasons is the most important, as well as the most widely accepted, reason for nurses using nursing process?
Correct Answer: C
Rationale: The nursing process's most important and widely accepted reason is facilitating communication with the healthcare team. This structured approach assessment, diagnosis, planning, implementation, evaluation creates a common language, ensuring physicians, therapists, and nurses align on client care. For example, documenting a client's respiratory distress via the process informs all team members, enhancing coordination. While it builds nursing knowledge, addresses health problems, and standardizes care, communication is the linchpin, enabling collaborative, effective interventions across disciplines.
