ATI Pathophysiology Exam 1
1. What property is found in clients with metastatic cancer?
- A. Tumors that are well encapsulated
- B. Tumors with slow, stable growth
- C. Cells that are genetically stable
- D. Cells invading local tissue and overrunning neighboring cells
Correct answer: D
Rationale: Metastatic cancer is characterized by cells that invade local tissue and overrun neighboring cells. Therefore, the correct answer is D. Choices A, B, and C are incorrect because metastatic cancer is associated with aggressive behavior where cells invade and spread to other parts of the body, rather than being well encapsulated, growing slowly, or being genetically stable.
2. A patient is prescribed tadalafil (Cialis) for erectile dysfunction. What critical contraindication should the nurse discuss with the patient?
- A. Use of nitrates
- B. Use of antihypertensive medications
- C. History of hypertension
- D. History of peptic ulcer disease
Correct answer: A
Rationale: The correct answer is A: Use of nitrates. Tadalafil (Cialis) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates potentiate the hypotensive effects of tadalafil, leading to a potentially life-threatening drop in blood pressure. Choices B, C, and D are incorrect because antihypertensive medications, history of hypertension, and history of peptic ulcer disease are not critical contraindications for tadalafil use. While caution may be needed in patients with certain conditions, the highest priority is addressing the interaction with nitrates.
3. What is a common significant side effect of opioid administration?
- A. Euphoria
- B. Diuresis
- C. Constipation
- D. Allergic reactions
Correct answer: C
Rationale: Constipation is one of the most common side effects of opioid administration due to the slowing down of gastrointestinal motility. Opioids affect the bowel movements, leading to constipation. Euphoria, while a possible effect, is less common than constipation. Diuresis is not a typical side effect of opioids; instead, urinary retention may occur. Allergic reactions are rare side effects of opioids, with symptoms such as rash, itching, or anaphylaxis.
4. Which medical problem is not generally associated with malnutrition?
- A. incontinence
- B. pressure sores
- C. celiac disease
- D. major surgery
Correct answer: A
Rationale: Incontinence is not typically associated with malnutrition, whereas conditions like pressure sores and celiac disease are directly linked to nutritional deficiencies and malabsorption.
5. The parents of a child with acute postinfectious glomerulonephritis (APIGN) ask how they will know that the condition is improving. How should the nurse respond?
- A. Your child’s urine output will increase, and the urine will become less brown in color.
- B. Your child will rest more comfortably.
- C. Your child’s appetite will decrease.
- D. Your child’s laboratory test values will show increased BUN.
Correct answer: A
Rationale: Improvement in APIGN is indicated by an increase in urine output and a change in urine color from brown (due to hematuria) to a more normal appearance. This reflects a reduction in glomerular inflammation and improved kidney function. Choice B is incorrect because resting more comfortably is not a direct indicator of kidney function improvement. Choice C is incorrect because a decrease in appetite is not typically associated with improvement in APIGN. Choice D is incorrect because an increased BUN value would suggest worsening kidney function rather than improvement.
