ATI Pathophysiology Exam 3 - Nurselytic

Correct Answer: C

Rationale: Contact dermatitis is typically caused by contact with a skin allergen that triggers an allergic reaction.
Choice A, fungal infection, is incorrect as contact dermatitis is not caused by fungi.
Choice B, long-term disorder from gout, is also incorrect as gout is not typically associated with contact dermatitis.
Choice D, Staphylococcal infection, is incorrect as contact dermatitis is primarily an allergic reaction rather than a bacterial infection.

Correct Answer: A

Rationale: The correct answer is A: Decreased plasma proteins. Edema can be caused by decreased plasma proteins, which reduce the osmotic pressure that keeps fluid in the blood vessels. Hypotension (choice
B) is low blood pressure and is not a direct cause of edema. Dehydration (choice
C) involves a lack of body fluid, but it is not a direct cause of edema. Polyuria (choice
D) is excessive urination and not a direct cause of edema.

Correct Answer: A

Rationale: The symptoms of headache, vomiting, blurred vision, and loss of consciousness following a concussion are indicative of increased intracranial pressure. These symptoms are commonly associated with intracranial pressure elevation, which can be dangerous and requires immediate medical attention. Lower extremity compartment syndrome is characterized by severe pain and swelling in the affected limb, not the symptoms mentioned. Consuming too much food at once may lead to digestive issues but does not correlate with the symptoms described. Improved kidney function would not manifest through the symptoms mentioned after a concussion.

Correct Answer: B

Rationale: The correct treatment for patients with hemophilia A is Factor VIII replacement. Hemophilia A is a genetic disorder where there is a deficiency in clotting factor VIII.
Therefore, replacing this factor is crucial in managing and preventing bleeding episodes.
Choice A, chemotherapy, is not the correct treatment for hemophilia A.
Choice C, heparin administration, is not recommended as it can further increase the risk of bleeding in patients with hemophilia.
Choice D, bone marrow transplant, is not a standard treatment for hemophilia A.

Correct Answer: A

Rationale: The correct answer is Parathyroid hormone (
Choice
A). Parathyroid hormone plays a key role in regulating calcium levels in the blood. When there is an imbalance in parathyroid hormone secretion, it can lead to increased calcium levels in the blood. Antidiuretic hormone (
Choice
B) is involved in regulating water balance, not calcium levels. Calcitonin (
Choice
C) helps lower blood calcium levels and is unlikely to cause an increase. Melatonin (
Choice
D) regulates sleep-wake cycles and does not have a direct effect on calcium levels in the blood.
