Correct Answer: D

Rationale: The correct answer is D because tracheal shift due to thyroid enlargement occurs when the thyroid gland enlarges and displaces the trachea to the opposite side. This is a common clinical finding in conditions like a goiter. Other choices are incorrect because: A is incorrect as tracheal shift is not related to systole; B is incorrect as tracheal shift is typically caused by a mass pushing the trachea; C is incorrect as pleural adhesions don't typically cause tracheal shift.

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: C

Rationale: The correct answer is C: Allergic rhinitis. The patient's symptoms of rhinorrhea, itching, and sneezing, along with pale, swollen turbinates and clear rhinorrhea, are indicative of allergic rhinitis. Allergic rhinitis is characterized by an allergic response to allergens, leading to inflammation of the nasal passages and increased mucus production. Nasal polyps (choice A) typically present with nasal congestion and reduced sense of smell. Acute sinusitis (choice B) would likely present with purulent nasal discharge and facial pain/pressure. Nasal carcinoma (choice D) is unlikely in this case due to the patient's symptoms and age.

Correct Answer: C

Rationale: The correct answer is C: turbinates. Turbinates are bony projections in the nasal cavity that increase the surface area for the warming, humidifying, and filtering of inhaled air. Meatus (A) refers to the passages in the nasal cavity, not the projections. Septum (B) is the partition between the nostrils, not the projections. Kiesselbach's plexus (D) is a collection of blood vessels in the nasal septum, not the projections that increase surface area.

Correct Answer: B

Rationale: The correct answer is B: hyphema. Hyphema is the presence of blood in the anterior chamber of the eye, which can occur due to trauma like being hit with a baseball bat. This indicates bleeding inside the eye, specifically in the space between the cornea and iris. Hypopyon (A) is the accumulation of white blood cells in the anterior chamber. Corneal abrasion (C) is a scratch on the cornea, not related to blood in the anterior chamber. Iritis (D) is inflammation of the iris, which does not necessarily involve blood in the anterior chamber.
