Correct Answer: D

Rationale: Phenazopyridine HCl (Pyridium) is a medication commonly used to relieve the pain, burning, and discomfort associated with urinary tract infections (UTIs). One of the notable side effects of Phenazopyridine is the discoloration of urine, turning it a rusty-red or orange color. This color change is harmless and temporary, but it can be alarming to patients who are unaware of this side effect. Therefore, if a patient undergoing treatment for a UTI notices their urine has turned orange, it is most likely due to the administration of Phenazopyridine.

Correct Answer: B

Rationale: Goiter is a condition characterized by the enlargement of the thyroid gland. The most common cause of goiter worldwide is iodine deficiency, which is required for the production of thyroid hormones. When there is insufficient iodine intake, the thyroid gland enlarges in an attempt to produce more hormones, leading to the development of goiter. While other factors can also contribute to the development of goiter, such as autoimmune diseases and certain medications, the primary cause associated with the condition is an iodine-deficient diet.

Correct Answer: B

Rationale: When a patient with a suspected spinal injury is found unconscious, the priority action is to secure the airway without jeopardizing the cervical spine. A jaw thrust maneuver is the appropriate technique to open the airway in this situation because it allows for the maintenance of neutral alignment of the cervical spine while ensuring proper ventilation. Moving the patient to a flat surface or applying a cervical collar could potentially worsen the spinal injury if not done correctly, and checking for responsiveness should only be done after ensuring a patent airway. Therefore, the safest and most effective initial action is to perform a jaw thrust maneuver to establish a clear airway.

Correct Answer: C

Rationale: Osteoporosis is a condition characterized by an imbalance between bone resorption (breakdown of bone tissue) and bone formation, leading to bone thinning and increased risk of fractures. In osteoporosis, bones become weak and porous, making them more prone to fractures even with minor trauma. This condition is common in postmenopausal women and older individuals. Risk factors for osteoporosis include age, gender, family history, lack of physical activity, low calcium and vitamin D intake, smoking, excessive alcohol consumption, and certain medications. Treatment typically involves lifestyle modifications, including adequate calcium and vitamin D intake, weight-bearing exercises, and sometimes medication to help slow down bone loss and reduce fracture risk. Early detection and management of osteoporosis are crucial to prevent fractures and maintain bone health.

Correct Answer: D

Rationale: The diagnosis of gestational diabetes mellitus (GDM) is typically confirmed through an oral glucose tolerance test (OGTT) during pregnancy. In GDM, the 2-hour plasma glucose level during the OGTT is equal to or greater than 140 mg/dL. This finding is characteristic of GDM and distinguishes it from other types of diabetes. Fasting blood glucose ≥126 mg/dL is diagnostic of diabetes mellitus outside of pregnancy, not specifically GDM. Random plasma glucose ≥200 mg/dL is indicative of uncontrolled diabetes in general. Hemoglobin A1c (HbA1c) ≥6.5% is used for diagnosing diabetes outside of pregnancy and is not specific to GDM.
