Pathophysiology Final Exam
1. A patient with erectile dysfunction is prescribed sildenafil (Viagra). What condition would contraindicate the use of this medication?
- A. History of hypertension
- B. Use of nitrates
- C. Recent use of antihypertensive medications
- D. History of peptic ulcer disease
Correct answer: B
Rationale: The correct answer is B: 'Use of nitrates.' Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, and their combined use can lead to a dangerous drop in blood pressure. Choices A, C, and D are incorrect because a history of hypertension, recent use of antihypertensive medications, or a history of peptic ulcer disease are not direct contraindications for using sildenafil.
2. Which breakfast items indicate an understanding of foods high in antioxidants A and C?
- A. Fried eggs, sausage, and whole wheat toast
- B. Oatmeal with blueberries and coffee
- C. Cereal with strawberries and low-fat milk
- D. Hard-boiled eggs, cantaloupe, and orange juice
Correct answer: D: Hard-boiled eggs, cantaloupe, and orange juice
Rationale: The correct answer is D: Hard-boiled eggs, cantaloupe, and orange juice. Cantaloupe and orange juice are rich in vitamins A and C, which are known for their antioxidant properties. Choice A is incorrect because fried eggs, sausage, and whole wheat toast do not contain high levels of antioxidants A and C. Choice B is incorrect because, while blueberries are high in antioxidants, coffee does not provide significant amounts of vitamins A and C. Choice C is incorrect because, although strawberries are a good source of vitamin C, low-fat milk does not contribute significantly to vitamins A and C.
3. What is the most consistent and commonly used indicator of pain in infants?
- A. Increased respirations
- B. Increased heart rate
- C. Thrashing of arms and legs
- D. Facial expression of discomfort
Correct answer: D
Rationale: Facial expression has consistently been validated as an indicator of pain in infants. Behavioral pain measures are most reliable for sharp procedural pain in infants. Increased heart rate and respirations are indicative of a generalized and complex response to stress, not specific for pain in infants. Thrashing of arms and legs is a reliable indicator in young children, not specifically in infants.
4. A nurse in a long-term care facility is developing strategies to promote increased food intake for an older adult client. Which of the following interventions should the nurse implement?
- A. Offer sugar substitutes to increase the client’s appetite.
- B. Provide opportunities to eat three large meals per day.
- C. Provide entertainment while the client is eating.
- D. Offer finger foods at mealtime.
Correct answer: D
Rationale: The correct intervention for promoting increased food intake for an older adult client is to offer finger foods at mealtime. Finger foods are easier for older adults to manage, making eating less cumbersome and more enjoyable, which can help increase overall food intake. Providing sugar substitutes (Choice A) may not necessarily increase appetite and could have negative health effects. Eating three large meals per day (Choice B) may be overwhelming and not suitable for older adults who may prefer smaller, more frequent meals. While providing entertainment (Choice C) during meals can be beneficial in some cases, it may not directly contribute to increased food intake as effectively as offering finger foods.
5. Which of the following should be included in a discussion of advance directives with new nurse graduates?
- A. According to the Patient Self-Determination Act, nurses are required to inform clients of their right to create an advance directive.
- B. The advance directive designates an individual who will make financial decisions for the client if he or she is unable to do so.
- C. A living will designates who will make health-care decisions for an individual in the event the individual is unable or incompetent to make his or her own decisions.
- D. The advance directive designates a health-care surrogate who will make known the client�s wishes regarding medical treatment if the client is unable to do so.
Correct answer: D
Rationale: One function of the advance directive is to appoint a health-care surrogate who will make known the client�s wishes for medical treatment to the medical and nursing team if the client is unable to do so.
