Explanation

• Visceral larva migrans is caused by the larvae of Toxocara canis (dog roundworm) migrating through internal organs.
• Cutaneous larva migrans, or 'creeping eruption', is caused by the larvae of animal hookworms like Ancylostoma braziliense burrowing in the skin.
• Swimmer's itch is an allergic reaction to the cercariae of schistosomes found in contaminated water.
• Larva currens ('running larva') is a rapidly moving skin track characteristic of infection with Strongyloides stercoralis.

Why Other Options Were Wrong

• Option B: This option incorrectly matches Visceral larva migrans with Strongyloides, Cutaneous larva migrans with Schistosomiasis, and Swimmer's itch with Toxocara canis.
• Option C: This option incorrectly matches Visceral larva migrans with Ancylostoma braziliense and Cutaneous larva migrans with Toxocara canis.
• Option D: This option incorrectly matches Visceral larva migrans with Schistosomiasis, Cutaneous larva migrans with Toxocara canis, and Swimmer's itch with Ancylostoma braziliense.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Matching parasitic infections with their causative agents as background academic context rather than a clinical decision trigger.
• Accurate identification of the causative parasite based on clinical presentation (e.g., speed of lesion migration in larva currens vs. CLM) is crucial for selecting the correct antiparasitic treatment.
• Nurses play a key role in patient education regarding prevention, such as avoiding contact with soil contaminated by pet feces (for CLM and VLM) and avoiding swimming in snail-infested waters (for swimmer's itch).
• What if? If a patient presents with a 'creeping eruption' that moves very rapidly (centimeters per hour), the diagnosis is more likely Larva currens (Strongyloides) rather than the more common, slower-moving Cutaneous larva migrans (Ancylostoma). This distinction is critical because strongyloidiasis can lead to a life-threatening hyperinfection syndrome in immunocompromised patients, requiring urgent and specific treatment.

How to Approach the Question

• This is a 'Match the Following' question. Start by identifying the pairs you are most certain about.
• For example, you might know that Visceral larva migrans is caused by Toxocara canis. This is pair 1-c.
• Look at the options. Only option A starts with '1-c'. This immediately suggests A is the likely answer.
• To confirm, check the other pairs in option A. Cutaneous larva migrans (2) is caused by Ancylostoma braziliense (d), Swimmer's itch (3) by Schistosomes (b), and Larva currens (4) by Strongyloides (a).
• Since all pairs in option A (1-c, 2-d, 3-b, 4-a) are correct, you can confidently select it.
