The parents of a 5-year-old have just found out that their child has head lice.
Which statement by the parents would support the nursing diagnosis of knowledge deficit?
Everybody in the house will need to be checked.
I can't believe it. We're not unclean, poor people.
That explains his complaints of itching on his neck.
We'll still have to use the nit comb even after the treatment.
The Correct Answer is B
Choice A rationale
This statement reflects correct knowledge because head lice infestations, or pediculosis capitis, are highly contagious and spread through close contact or shared items, making it essential to check all household members to prevent reinfestation and ensure effective eradication of the parasites.
Choice B rationale
This statement supports a nursing diagnosis of knowledge deficit because it indicates a misconception that head lice are associated only with poor hygiene or low socioeconomic status, when in fact, lice infestation is unrelated to cleanliness and can occur in any population group through head-to-head contact.
Choice C rationale
This statement demonstrates correct knowledge because itching, particularly around the ears, neck, and scalp, is a common clinical manifestation of pediculosis capitis, caused by the louse saliva irritating the scalp, thus the parent correctly links the symptom to the new diagnosis.
Choice D rationale
This statement shows correct understanding of treatment because the nit comb is crucial for manually removing nits (lice eggs) that may remain attached to the hair shaft even after chemical pediculicide treatment, which often only kills live lice but not all the eggs.

Correct Answer is A
Explanation
Choice A rationale
Mumps is a viral infection caused by a paramyxovirus, primarily characterized by painful swelling of the parotid salivary glands, leading to pain on chewing or near the earlobe. In post-pubertal males, like this 15-year-old, mumps can also cause orchitis, which is the inflammation and swelling of one or both testes, perfectly aligning with the client's symptoms. The general symptoms of fever, headache, and malaise are also typical of the prodromal phase of mumps infection.
Choice B rationale
Poliomyelitis, caused by the poliovirus, primarily affects the central nervous system, leading to muscle weakness and paralysis, particularly in the lower limbs. While it can cause non-specific symptoms like fever and headache, it does not typically cause parotid gland swelling (parotitis) or testicular swelling (orchitis), making this diagnosis inconsistent with the client's constellation of specific findings.
Choice C rationale
Infectious mononucleosis, caused by the Epstein-Barr virus (EBV), is commonly known as the "kissing disease" and typically presents with a classic triad of fever, pharyngitis (sore throat), and lymphadenopathy (swollen lymph nodes). Although it can cause generalized malaise, it does not characteristically cause parotid swelling or orchitis, which are key features in this client's presentation.
Choice D rationale
Herpes zoster, or shingles, is caused by the reactivation of the varicella-zoster virus (VZV) and manifests as a painful, blistering rash typically confined to a dermatome, or specific sensory nerve distribution. It rarely presents only with fever, headache, malaise, parotitis, and orchitis without a dermatomal rash, making this an unlikely diagnosis for these symptoms.
Correct Answer is B
Explanation
Choice A rationale
Violence, including homicides and non-fatal assaults, is a significant cause of injury and death among adolescents, particularly in certain demographics, reflecting underlying social and environmental stresses. However, statistically, unintentional injuries are the leading cause of death in this age group, and motor vehicle crashes are the single greatest contributor to these unintentional injury deaths.
Choice B rationale
Motor vehicle crashes are the leading cause of unintentional injury, morbidity, and mortality among adolescents aged 15 to 20 years. Factors contributing to this include inexperience, distracted driving, night driving, impaired driving, and not using safety belts. The combination of risk-taking behaviors and the acquisition of new driving privileges makes this the major cause of death in this population.
Choice C rationale
Suicide is a leading cause of death in the adolescent population and is classified as an intentional injury. It represents a serious public health issue related to mental health crises. While extremely important to address, the question asks for the major cause of unintentional injuries, which differentiates it from intentionally self-inflicted injuries like suicide.
Choice D rationale
Drowning is a notable, tragic cause of unintentional injury death, often related to recreational activities, lack of supervision, or risk-taking near water, especially in older adolescents. However, the overall frequency of fatalities from motor vehicle crashes significantly surpasses the number of fatalities caused by drowning in the broader adolescent age group.
