health assessment practice questions nursing

Correct Answer: C

Rationale: The correct answer is C: the presence of shadows, which may indicate glaucoma. When a light is directed across the iris from the temporal side, it helps in evaluating the presence of shadows in the anterior chamber angle, which can suggest a narrow or closed angle glaucoma. This technique is known as transillumination test and is important in detecting potential glaucoma cases. A: Drainage from dacryocystitis is incorrect as it is typically assessed by pressing on the lacrimal sac area to observe for discharge. B: Conjunctivitis over the iris is incorrect as conjunctivitis is an inflammation of the conjunctiva, not the iris. D: A scattered light reflex indicative of cataracts is incorrect as cataracts cause clouding of the lens, not scattering of light across the iris.

Correct Answer: B

Rationale: The correct answer is B: Lyme disease. The presentation of a red circular rash with central clearing, known as erythema migrans, following a hiking trip in the summer is highly indicative of Lyme disease. The specific distribution of the rash across the midriff and behind the knees aligns with typical areas where the rash appears in Lyme disease cases. This rash is a hallmark sign of early Lyme disease caused by the bacterium Borrelia burgdorferi transmitted through the bite of an infected tick. Other answer choices are incorrect because rubeola presents with a different rash pattern, an allergy to mosquito bites would not typically present in this manner, and Rocky Mountain spotted fever typically presents with a different rash appearance and distribution.

Correct Answer: A

Rationale: The correct answer is A: tinea capitis. Tinea capitis is a fungal infection of the scalp that can cause hair loss, scaling, and breakage of hair. In this case, the patient's symptoms of hair loss, patchy hair breakage, and scaling on the scalp are consistent with tinea capitis. The nurse should suspect tinea capitis based on the presentation of these specific symptoms in the patient. Summary: - B: tinea corporis is a fungal infection of the skin, not the scalp, so it is not the most likely cause of the patient's symptoms. - C: toxic alopecia refers to hair loss due to exposure to toxins, which is unlikely in this case based on the symptoms described. - D: seborrheic dermatitis is a common skin condition that causes redness, scaly patches, and dandruff on the scalp, but it does not typically cause hair loss in the same way as tinea capitis

Correct Answer: A

Rationale: The correct answer is A because one pinch of smokeless tobacco (SLT) in the mouth for 30 minutes can indeed deliver a similar amount of nicotine as smoking one cigarette. This is because the nicotine in SLT is absorbed through the oral mucosa directly into the bloodstream, providing a quick effect. This statement is accurate and reflects the pharmacokinetics of SLT use. Option B is incorrect because smoking carries a higher risk of oral cancer compared to SLT use. Option C is incorrect as pain is not always an early sign of oral cancer, and other symptoms such as non-healing sores or lumps may indicate oral cancer. Option D is incorrect as pain can sometimes be an early sign of oral cancer, especially in advanced stages.

Correct Answer: C

Rationale: The correct answer is C: Spoon nails. In iron-deficiency anemia, the nails may develop a concave or spoon-like shape (koilonychia). This is due to the decreased oxygen supply to the nail bed. The characteristic spoon nails are indicative of severe iron deficiency. Splinter hemorrhages (choice A) are small areas of bleeding under the nails and are more commonly associated with conditions like endocarditis. Paronychia (choice B) is an infection around the nail, not specific to anemia. Beau's lines (choice D) are horizontal depressions in the nails, typically seen after a period of severe illness or stress, rather than specifically in iron-deficiency anemia.
