LPN Fundamentals Exam Questions
Question 1 of 5
Percentage of bilirubin production from old RBCs is:
Correct Answer: B
Rationale: About 80% of bilirubin comes from hemoglobin breakdown in old red blood cells, processed by the spleen and liver. The rest (20%) is from other heme sources (e.g., myoglobin). Nurses monitor bilirubin in jaundice, understanding its RBC origin to assess liver function or hemolysis, critical for diagnosing underlying conditions.
Question 2 of 5
The most important skills needed to obtain accurate information from your client is:
Correct Answer: C
Rationale: Good communication and critical thinking are the most crucial skills for obtaining accurate client information. Communication listening, questioning, clarifying builds trust, encouraging honest responses (e.g., detailed pain history). Critical thinking analyzes these responses, spotting inconsistencies or probing deeper (e.g., linking fatigue to sleep issues), ensuring data reliability. Teaching and assessment are roles, not skills for gathering data; teaching informs, doesn't collect. Cognitive skills overlap with critical thinking, but pairing with teaching misses communication's primacy. Psychomotor skills (e.g., taking vitals) and courage are useful but secondary manual tasks don't extract perceptions, and bravery doesn't ensure accuracy. Communication and critical thinking together elicit and interpret client input effectively, foundational for a precise, comprehensive assessment in nursing.
Question 3 of 5
Eyedrops should be administered in which anatomic location:
Correct Answer: D
Rationale: Eyedrops are administered into the lower conjunctival sac formed by pulling the lower eyelid down ensuring medication spreads across the eye evenly when the patient blinks. This maximizes absorption and minimizes runoff, critical for efficacy (e.g., glaucoma drops). The inner canthus (near the nose) risks drainage into the tear duct, reducing dose and potentially causing systemic effects. 'Other canthus' likely means outer canthus (lateral), less effective for retention, as it's not a sac. The upper conjunctival sac is harder to access, requiring awkward lid lifting, and less practical. The lower sac's anatomical suitability holding drops naturally makes it the standard site, ensuring therapeutic delivery and patient comfort, per ophthalmic administration protocols.
Question 4 of 5
A walk-in client enters into the clinic with a chief complaint of abdominal pain and diarrhea. The nurse takes the client's vital signs hereafter. What phase of nursing process is being implemented here by the nurse?
Correct Answer: A
Rationale: Taking vital signs is part of the assessment phase, gathering data about the client's condition.
Question 5 of 5
The nurse is ordered to administer ampicillin capsule TID p.o. The nurse should give the medication...
Correct Answer: A
Rationale: TID p.o. means three times a day by mouth, regardless of meal timing unless specified.
