ATI Pathophysiology Exam 3
1. When arterial blood pressure declines, the kidneys secrete a hormone to increase blood pressure and peripheral resistance. What is this hormone called?
- A. Renin
- B. Antidiuretic hormone
- C. Atrial natriuretic
- D. Insulin
Correct answer: A
Rationale: Renin is the correct answer. When arterial blood pressure decreases, the kidneys release renin, which triggers a series of reactions ultimately leading to an increase in blood pressure and peripheral resistance. Antidiuretic hormone (choice B) is involved in water retention, atrial natriuretic hormone (choice C) promotes sodium excretion and lowers blood pressure, and insulin (choice D) regulates glucose metabolism, not blood pressure.
2. A healthcare professional is assessing a client with suspected myasthenia gravis. Which symptom would the healthcare professional expect to find?
- A. Muscle atrophy
- B. Facial weakness
- C. Ptosis and diplopia
- D. Increased muscle tone
Correct answer: C
Rationale: Ptosis (drooping eyelid) and diplopia (double vision) are classic symptoms of myasthenia gravis. Muscle atrophy (Choice A) is not a typical early manifestation of myasthenia gravis. While facial weakness (Choice B) can occur, it is not as specific as ptosis and diplopia. Increased muscle tone (Choice D) is more indicative of conditions like spasticity, not myasthenia gravis.
3. Which goal is a priority for a client with a DSM-IV-TR diagnosis of delirium and the nursing diagnosis Acute confusion related to recent surgery secondary to traumatic hip fracture?
- A. The client will complete activities of daily living.
- B. The client will maintain safety.
- C. The client will remain oriented.
- D. The client will understand communication.
Correct answer: B
Rationale: The correct answer is B: 'The client will maintain safety.' For a client with delirium, especially in the context of acute confusion post-surgery, safety is the top priority. Delirium can lead to disorientation, impaired decision-making, and increased risk of falls or accidents. Ensuring the client's safety by implementing measures to prevent harm is crucial. Choices A, C, and D are important but not the priority in this scenario. Completing activities of daily living, remaining oriented, and understanding communication are relevant goals but come after ensuring the client's safety in the presence of delirium and acute confusion.
4. A client with a history of deep vein thrombosis (DVT) is receiving anticoagulant therapy. Which complication should the nurse monitor for?
- A. Pulmonary embolism
- B. Gastrointestinal bleeding
- C. Hemorrhagic stroke
- D. Renal insufficiency
Correct answer: A
Rationale: The correct answer is A, pulmonary embolism. In a client with a history of deep vein thrombosis (DVT) receiving anticoagulant therapy, the nurse should monitor for pulmonary embolism, as it is a serious complication. Pulmonary embolism occurs when a blood clot dislodges from the veins and travels to the lungs, potentially causing life-threatening consequences. Choices B, gastrointestinal bleeding, C, hemorrhagic stroke, and D, renal insufficiency, are not directly associated with deep vein thrombosis or anticoagulant therapy. While these complications may occur in other situations, they are not the primary concern when managing a client with a history of DVT.
5. A woman is complaining that she feels like the room is spinning even though she is not moving. Which of the following is characteristic of benign positional vertigo?
- A. It usually occurs with a headache.
- B. Pupillary changes are common.
- C. It is usually triggered when the patient bends forward.
- D. Nystagmus continues even when eyes fixate on an object.
Correct answer: C
Rationale: Benign positional vertigo is typically triggered by changes in head position, such as bending forward or turning over in bed. This change in position leads to brief episodes of vertigo, often associated with nystagmus, which is rapid, involuntary eye movements. Pupillary changes and headaches are not typical features of benign positional vertigo, making choices B and A incorrect. Nystagmus in benign positional vertigo usually stops when the eyes fixate on an object, so choice D is also incorrect.
