Tiny, white, clear or brown oval specs, adhering tightly to hair shafts.

Answer and Explanation

The Correct Answer is D

A. Scales, redness, and flakes that fall off easily are more consistent with seborrheic dermatitis (dandruff) rather than pediculosis capitis.
B. Patches of redness and alopecia associated with animal contact suggest tinea capitis (fungal infection), not lice.
C. Linear burrows with intense nighttime itching are characteristic of scabies, caused by mites under the skin, not head lice.
D. Tiny, white, clear, or brown oval nits (lice eggs) that adhere firmly to the hair shaft are the hallmark finding of pediculosis capitis, confirming the infestation.

Correct Answer is D

Explanation

A. Acetaminophen is not effective in treating heat stroke, as this condition is not caused by an infection or hypothalamic reset but by failure of thermoregulation.
B. Warm blankets would worsen hyperthermia and are contraindicated in heat stroke.
C. Warm IV fluids would further increase body temperature, worsening the client’s condition.
D. The client is showing signs of heat stroke (very high temperature, confusion, tachycardia, tachypnea, and environmental exposure). The priority intervention is rapid cooling, which includes using cooled IV fluids, cooling blankets, ice packs to the groin/axillae, and removing excess clothing. This helps to lower the dangerously high core temperature and prevent organ failure.

A. Eat several small meals a day rather than three larger meals. B. Attend screening clinics at least twice per year. C. Exercise for at least 30 minutes, three times a week D. Clients who smoke should attend smoking cessation classes E. Wash area with a pediculicide

Correct Answer is D

Explanation

A. Eating several small meals may help with certain gastrointestinal conditions (like GERD), but it is not directly linked to reducing the risk of peptic ulcer disease.
B. Routine screening clinics are not standard for peptic ulcer disease prevention; screening is generally focused on high-risk conditions such as cancers.
C. Regular exercise is beneficial for overall health but does not directly reduce the risk factors for peptic ulcer disease.
D. Smoking is a known risk factor for peptic ulcer disease because it increases gastric acid secretion, impairs mucosal defenses, and delays ulcer healing. Teaching clients who smoke to attend smoking cessation classes is the most appropriate prevention-focused intervention.
