A group of football players is taking oral griseofulvin for tinea pedis.
What should the school nurse caution them to avoid?

Choice A rationale

While occlusive agents like Vaseline can smother lice, this method is messy and generally not as effective as targeted pediculicides. It mainly suffocates the live lice but does not consistently eliminate the nits (eggs), which are tightly attached to the hair shaft and must be removed to prevent reinfestation.

Choice B rationale

A soda-vinegar solution has no proven efficacy in eradicating lice. The acetic acid in vinegar can help loosen the glue-like substance that attaches nits to the hair shaft, but it is not a standalone treatment. Baking soda does not have any scientific basis for being effective against pediculosis.

Choice C rationale

A vinegar-water solution, specifically the acetic acid in vinegar, helps to dissolve the proteinaceous cement substance that glues nits to the hair shaft. This makes the nits easier to remove with a fine-toothed nit comb, which is a crucial step in the eradication process to prevent the hatching of new lice.

Choice D rationale

Dish detergents are not formulated to be effective against lice and can be harsh on the scalp, causing irritation. They lack the specific neurotoxic agents or suffocation properties found in approved pediculicide shampoos that are designed to kill lice and their eggs. This method is ineffective and potentially harmful. .

Choice A rationale

Ambulating with assistance is not an immediate indicator of a positive outcome for a client with a DVT. Ambulation is often contraindicated in the initial stages of treatment to prevent a pulmonary embolism. Therefore, this assessment does not reflect a primary outcome of DVT management, which focuses on preventing complications and resolving the clot.

Choice B rationale

An oxygen saturation of 98% is a critical indicator that the client has not developed a pulmonary embolism, a serious and life-threatening complication of DVT. This outcome demonstrates that the thrombus has not dislodged and traveled to the lungs, obstructing gas exchange. Normal oxygen saturation levels range from 95% to 100%.

Choice C rationale

While pain reduction is an important aspect of care, a pain score of 2/10 after medication is a temporary relief measure and does not represent a definitive outcome for DVT. The primary goal is to prevent a pulmonary embolism and resolve the thrombus, and pain control is a supportive measure in achieving that goal.

Choice D rationale

Verbalizing risk factors indicates that the client has received education, which is an important intervention. However, it is an educational outcome, not a physiological one. It does not provide direct evidence that the DVT is resolving or that the client is free from the most serious complication of the disease, a pulmonary embolism.
