Pathophysiology Practice Questions
1. During the home visit of a client with dementia, the nurse notes that an adult daughter persistently corrects her father’s misperceptions of reality, even when the father becomes upset and anxious. Which intervention should the nurse teach the caregiver?
- A. Anxiety-reducing measures
- B. Positive reinforcement
- C. Reality orientation techniques
- D. Validation techniques
Correct answer: D
Rationale: The correct answer is D: Validation techniques. In dementia care, using validation techniques involves acknowledging the person's feelings and reality, even if it differs from actual events or facts. It helps in reducing the client's anxiety and distress. In this scenario, the daughter persistently correcting her father's misperceptions can escalate his anxiety. Teaching the daughter validation techniques will encourage her to validate her father's feelings and perceptions, ultimately promoting a more supportive and less confrontational environment. Choices A, B, and C are incorrect in this context. While anxiety-reducing measures can be beneficial, the primary issue here is the father's misperceptions being consistently corrected. Positive reinforcement focuses on rewarding desired behaviors, which is not directly related to the situation described. Reality orientation techniques involve constantly reminding the person of the correct time, place, and other details, which may not be suitable for someone with dementia experiencing distress.
2. A teacher in a preschool is diagnosed with giardiasis. Which of the following medications will be administered to treat the diarrhea and abdominal distention?
- A. Sulfasalazine (Azulfidine)
- B. Metronidazole (Flagyl)
- C. Trimethoprim–sulfamethoxazole (Bactrim)
- D. Doxycycline (Vibramycin)
Correct answer: B
Rationale: The correct answer is B. Metronidazole (Flagyl) is the drug of choice for treating giardiasis, which is a common cause of diarrhea and abdominal distention. Sulfasalazine (Choice A) is used to treat inflammatory bowel disease. Trimethoprim–sulfamethoxazole (Choice C) is commonly used for urinary tract infections and Pneumocystis jirovecii pneumonia. Doxycycline (Choice D) is commonly used to treat various bacterial infections but is not the first-line treatment for giardiasis.
3. What is the common denominator of all forms of heart failure?
- A. Pulmonary edema
- B. Jugular venous distention
- C. Peripheral edema
- D. Reduced cardiac output
Correct answer: D
Rationale: The correct answer is D: Reduced cardiac output. All forms of heart failure share the common denominator of reduced cardiac output, which leads to inadequate tissue perfusion. Pulmonary edema (choice A) is a consequence of heart failure but not the common denominator. Jugular venous distention (choice B) and peripheral edema (choice C) are signs of heart failure but do not represent the common denominator shared by all forms.
4. Which of the following characterizes ductal carcinoma in situ?
- A. It is less common than lobular carcinoma in situ.
- B. Malignant cells have not invaded the stroma.
- C. It is considered a cancer precursor.
- D. Malignant cells have not invaded the stroma; it is considered a cancer precursor and has a higher risk for invasive cancer compared to lobular carcinoma in situ.
Correct answer: D
Rationale: The correct answer is that ductal carcinoma in situ is characterized by malignant cells that have not invaded the stroma, making it a cancer precursor with a higher risk for invasive cancer compared to lobular carcinoma in situ. Choice A is incorrect because ductal carcinoma in situ is more common than lobular carcinoma in situ. Choice B is incorrect as it only partially describes ductal carcinoma in situ without mentioning its potential for progression to invasive cancer. Choice C is incorrect because it does not capture the complete characteristics of ductal carcinoma in situ, which include the risk for invasive cancer.
5. A patient is diagnosed with type 2 diabetes mellitus. Which of the following is a common initial treatment strategy?
- A. Insulin therapy
- B. Lifestyle modification and metformin
- C. Sulfonylureas
- D. Thiazolidinediones
Correct answer: B
Rationale: The correct answer is B: Lifestyle modification and metformin. When managing type 2 diabetes mellitus, initial treatment often involves lifestyle changes such as adopting a healthy diet and increasing physical activity, along with the oral medication metformin. Insulin therapy (choice A) is usually reserved for cases where lifestyle changes and oral medications are not sufficient to control blood sugar levels. Sulfonylureas (choice C) and thiazolidinediones (choice D) are also oral medications used in diabetes management, but they are not typically recommended as first-line treatments due to various side effects and considerations in type 2 diabetes management.
