health assessment practice questions nursing

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: B

Rationale: The correct answer is B: damage to the trigeminal nerve. Trigeminal nerve damage can result in the inability to differentiate between sharp and dull sensations on the face. The trigeminal nerve is responsible for transmitting sensory information from the face to the brain. Bell's palsy (choice A) affects facial muscles, not sensory perception. Frostbite (choice C) typically causes numbness rather than loss of sensation discrimination. Scleroderma (choice D) is a connective tissue disorder that does not directly affect sensory perception on the face.

Correct Answer: A

Rationale: The correct answer is A: At birth, the head is one fifth the total length. This is because newborns have relatively larger heads compared to their body size. This is known as cephalocaudal growth, where development starts from the head and progresses down the body. The head being one-fifth of the total length is a normal proportion in newborns. Choice B is incorrect because at birth, the chest circumference is usually greater than the head circumference. Choice C is incorrect as the head size reaches about 80% of its final size by age 2, not 3 years old. Choice D is incorrect because the closure of the anterior fontanelle at 2 months does not necessarily mean the head will appear proportionate to the body; it continues to grow in proportion to the body size.

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.

Correct Answer: D

Rationale: The signs and symptoms - severe headache, high fever, and neck stiffness - in a young adult point towards meningeal inflammation. The combination of these symptoms is indicative of a potential infection or inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. The presence of fever and neck stiffness, in addition to the severe headache, raises concern for meningitis, an infection of the meninges. This is a medical emergency that requires prompt evaluation and treatment. Other choices are incorrect because: A: Head injury usually presents with a history of trauma, which is not mentioned in the scenario. B: Cluster headaches typically do not present with fever and neck stiffness. C: Migraine headaches do not typically cause such high fever and neck stiffness.
