Diabetes insipidus is the result of:

Correct Answer: D

Rationale: Diabetes insipidus is caused by a disorder of the pituitary gland affecting ADH regulation. This disorder results in the decreased production or release of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Choices A, B, and C are incorrect as they do not relate to the underlying cause of diabetes insipidus.

Correct Answer: D

Rationale: The correct answer is D. An avulsion fracture occurs when a part of the bone is pulled away by a tendon or ligament. Choice A is incorrect because it describes an open fracture where the bone penetrates the skin. Choice B is incorrect as a pathological fracture results from an underlying disease weakening the bone, not physical trauma. Choice C is incorrect as a greenstick fracture involves the bone bending but not completely breaking.

Rationale: The correct answer is D because adjuvant medications are often available over the counter without a prescription. Choices A, B, and C are incorrect.

Correct Answer: D

Rationale: The correct action to take when a patient becomes hypotensive with a bounding, rapid pulse rate after administering penicillin intravenously is to stop the intravenous flow immediately. This can help prevent further complications by discontinuing the administration of the medication that might be causing the adverse effects. Decreasing or increasing the rate of medication flow may not address the underlying issue of the patient's adverse reaction. While it's important to involve the healthcare provider in such situations, the immediate priority is to halt the administration of the medication.

Correct Answer: B

Rationale: An abscess is defined as a cavity containing pus surrounded by inflamed tissue. Cellulitis is a bacterial skin infection causing redness and swelling, not a cavity. Extravasation is the leakage of fluid from a vessel into surrounding tissues, not a cavity. An adhesion is a band of scar-like tissue that binds two parts together, not a cavity containing pus and inflamed tissue.
