(PN/LPN) Verified Study Questions and Answers
Elaborate Rationales GRADE A+
1.
A nurse is performing hand hygiene after removing gloves used while emptying a urinary
catheter drainage bag. The nurse’s hands are not visibly soiled. Which method of hand hygiene is
most appropriate?
A. Rinse hands briefly with water only
B. Apply alcohol-based hand rub and rub until dry
C. Wash hands with soap for 5 seconds
D. Wipe hands with a dry paper towel
Rationale:
When hands are not visibly soiled, alcohol-based hand sanitizer is the preferred method because
it effectively reduces microbial count and requires less time than soap and water. It must be
rubbed over all hand surfaces until completely dry to ensure effectiveness. Plain water alone
does not remove microorganisms, and washing for only 5 seconds is inadequate for proper
decontamination.
2.
A nurse is caring for a client who suddenly reports dizziness upon standing from a lying position.
The nurse suspects orthostatic hypotension. Which action should the nurse take first?
A. Encourage the client to walk to improve circulation
B. Document the finding in the chart
C. Assist the client back to a seated or lying position
D. Administer an antihypertensive medication
Rationale:
The priority is client safety. Orthostatic hypotension can lead to falls due to decreased cerebral
perfusion. Assisting the client back to a safe position prevents injury. Documentation is
important but secondary to immediate safety. Administering antihypertensives would worsen the
hypotension.
,3.
A nurse is reinforcing teaching with a client about proper use of a cane for ambulation due to
left-sided weakness. Which instruction is correct?
A. Hold the cane on the weaker side
B. Hold the cane on the stronger side
C. Move the strong leg forward first
D. Advance the cane after moving both legs
Rationale:
The cane should be held on the stronger side to provide support to the weaker extremity. The
correct sequence is to move the cane forward with the weaker leg, then advance the stronger leg.
This technique improves balance and stability. Holding the cane on the weak side reduces
effectiveness and increases fall risk.
4.
A nurse is preparing to administer an oral medication to a client who has difficulty swallowing
tablets. What is the most appropriate action?
A. Crush all medications and mix with food
B. Verify whether the medication can be safely crushed
C. Skip the medication
D. Dissolve the medication in water without checking
Rationale:
Not all medications are safe to crush, especially extended-release or enteric-coated formulations.
Crushing inappropriate medications can alter absorption and effectiveness. The nurse must verify
with a pharmacist or medication reference before altering the form. Client safety requires
checking compatibility prior to modification.
5.
A nurse is caring for a client with a stage 1 pressure injury on the sacrum. Which intervention is
appropriate?
A. Apply a heating pad
B. Reposition the client at least every 2 hours
,C. Massage the reddened area
D. Leave the area open to air without monitoring
Rationale:
Stage 1 pressure injuries involve non-blanchable redness with intact skin. Repositioning every 2
hours reduces pressure and improves circulation to prevent progression. Massaging the area can
worsen tissue damage. Heat increases metabolic demand and may further injure tissue.
6.
A nurse is monitoring a client receiving opioid analgesics for postoperative pain. Which finding
requires immediate intervention?
A. Respiratory rate of 10 breaths per minute
B. Mild drowsiness
C. Respiratory rate of 8 breaths per minute
D. Pain rating of 4 out of 10
Rationale:
Opioids can cause respiratory depression. A respiratory rate below 12 breaths per minute is
concerning, and a rate of 8 indicates severe depression requiring immediate intervention. The
nurse may need to withhold medication and prepare to administer naloxone per protocol. Early
recognition prevents life-threatening complications.
7.
A nurse is assisting with fire safety education in a healthcare facility. According to PASS, what
does the first “P” represent when using a fire extinguisher?
A. Pull the pin
B. Protect the client
C. Push the alarm
D. Position near exit
Rationale:
PASS stands for Pull, Aim, Squeeze, Sweep. The first step is to pull the pin to unlock the
extinguisher. Understanding fire safety protocols ensures rapid and effective response. This
sequence promotes safe and controlled fire suppression.
, 8.
A nurse is reinforcing teaching to a client newly diagnosed with type 2 diabetes about
recognizing hypoglycemia. Which symptom should the nurse include?
A. Increased thirst
B. Shakiness and sweating
C. Fruity breath odor
D. Deep rapid respirations
Rationale:
Shakiness and sweating are classic signs of hypoglycemia due to activation of the sympathetic
nervous system. Increased thirst and fruity breath are associated with hyperglycemia. Early
recognition allows prompt treatment with fast-acting carbohydrates to prevent complications
such as seizures.
9.
A nurse observes a coworker accessing a client’s electronic health record without being assigned
to the client’s care. What is the appropriate action?
A. Ignore the behavior
B. Confront the coworker publicly
C. Report the incident according to facility policy
D. Document the event in the client chart
Rationale:
Accessing a client’s record without authorization violates HIPAA and confidentiality laws. The
nurse has a professional responsibility to report privacy breaches through appropriate channels.
Maintaining confidentiality protects client rights and upholds ethical standards.
10.
A nurse is preparing a sterile field for a dressing change. Which action contaminates the sterile
field?
A. Keeping the sterile field at waist level
B. Opening packages away from the body
C. Reaching across the sterile field
D. Keeping the sterile field in constant view
