HESI LPN Fundamentals Test Questions
Question 1 of 5
Which of the following people have the largest percentage of water in their bodies?
Correct Answer: B
Rationale: Lean men have the highest water percentage, around 60-65%, due to less fat, unlike fat men, women, or fat women. Nurses apply this in fluid assessments.
Question 2 of 5
A client with anemia presents with fatigue and decreased exercise tolerance. What is the primary indication for initiating oxygen therapy in this client?
Correct Answer: A
Rationale: Increasing oxygen-carrying capacity (A) is the primary indication for oxygen therapy in anemia, compensating for reduced hemoglobin by boosting dissolved oxygen in plasma. Reducing iron deficiency (B) or enhancing erythropoiesis (D) requires other treatments. Tissue healing (C) is a byproduct. This approach mitigates hypoxia symptoms, per hematology care, vital until anemia is corrected.
Question 3 of 5
The nurse is caring for a client with a tracheostomy receiving oxygen therapy. Which intervention should the nurse prioritize to prevent infection and ensure proper oxygen delivery?
Correct Answer: C
Rationale: Applying a sterile dressing (C) over the tracheostomy site prevents infection by barring pathogens and supports oxygen delivery by maintaining a clean airway. Suctioning (A) clears secretions but not infection. Hourly RR (B) is monitoring, not prevention. Humidified oxygen (D) aids comfort, not sterility. Sterile dressing, per tracheostomy care, is the priority.
Question 4 of 5
Which of the following skin lesions is associated with Lyme's disease?
Correct Answer: A
Rationale: A bull's-eye rash (erythema migrans) is a hallmark of Lyme disease, appearing at the tick bite site with a red center and concentric rings, signaling Borrelia infection. Papular crusts, bullae, or plaques align with other conditions, not Lyme's classic presentation. Nurses recognize this lesion for early diagnosis, prompting timely antibiotic treatment to prevent complications like arthritis or neurological issues.
Question 5 of 5
A client with schizophrenia is receiving depot injections of Haldol Decanoate (haloperidol decanoate). The client should be told to return for his next injection in:
Correct Answer: C
Rationale: Haldol Decanoate, a long-acting antipsychotic depot, is typically administered every 4 weeks, maintaining steady haloperidol levels for schizophrenia control, per psychiatric pharmacology. Shorter intervals suit oral forms; 6 weeks risks gaps. Nurses schedule this, instructing clients on timing to ensure compliance and symptom stability, balancing convenience with therapeutic efficacy.
