Final Exam Pathophysiology
1. A patient with a history of osteoporosis is prescribed alendronate (Fosamax). What instructions should the nurse provide to ensure the effectiveness of the medication?
- A. Take the medication with a full glass of water and remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption.
- B. Take the medication with milk to enhance calcium absorption.
- C. Take the medication at bedtime to ensure absorption during sleep.
- D. Take the medication with food to prevent nausea.
Correct answer: A
Rationale: The correct answer is A. Alendronate should be taken with a full glass of water and patients should remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption. Taking the medication with milk (choice B) is not recommended as it may interfere with the absorption of alendronate. Taking the medication at bedtime (choice C) is not necessary for optimal absorption. Taking the medication with food (choice D) is also not recommended as food can reduce the absorption of alendronate.
2. What is extinction and how might it be used in treating a disorder?
- A. Extinction strengthens the conditioned response by continuously pairing the conditioned stimulus with the unconditioned stimulus.
- B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus.
- C. Extinction is ineffective and is not used in treating disorders.
- D. Extinction is the process of intensifying the conditioned response by pairing the conditioned stimulus with a stronger unconditioned stimulus.
Correct answer: B
Rationale: The correct answer is B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. This helps in reducing or eliminating undesired behaviors. Choice A is incorrect because extinction does not strengthen the conditioned response but weakens it. Choice C is also incorrect as extinction is a valid technique used in treating disorders by reducing unwanted behaviors. Choice D is incorrect as extinction does not involve intensifying the conditioned response but rather diminishing it.
3. A nurse in the PACU is caring for a client who has received general anesthesia and has a manifestation of malignant hyperthermia. The nurse should expect to administer which of the following medications?
- A. Acetaminophen
- B. Ibuprofen
- C. Dantrolene
- D. Diazepam
Correct answer: C
Rationale: Corrected Rationale: Dantrolene is the medication of choice to treat malignant hyperthermia, a life-threatening reaction to general anesthesia. It works by inhibiting the release of calcium ions in skeletal muscle cells, preventing muscle contracture and hypermetabolism. Acetaminophen (Choice A) and ibuprofen (Choice B) are not indicated for treating malignant hyperthermia. Diazepam (Choice D) may be used to control muscle spasms but is not the first-line treatment for malignant hyperthermia.
4. The nurse is preparing to admit a child to the hospital with a diagnosis of minimal change nephrotic syndrome. The nurse understands that the peak age at onset for this disease is what?
- A. 2 to 3 years
- B. 4 to 5 years
- C. 6 to 7 years
- D. 8 to 9 years
Correct answer: B
Rationale: The peak age for the onset of minimal change nephrotic syndrome (MCNS) is typically between 4 and 5 years old. MCNS is the most common cause of nephrotic syndrome in children, particularly within this age range.
5. A client at 37 weeks of gestation is scheduled for a nonstress test. What information should the nurse include?
- A. You will be given oxytocin during the test.
- B. You will need to fast for 12 hours before the test.
- C. You will need to drink orange juice before the test.
- D. You will need to have a full bladder during the test.
Correct answer: C
Rationale: The correct answer is C. Drinking orange juice before the nonstress test can increase fetal movement, which is essential for an accurate reading. Choice A is incorrect because oxytocin is not typically administered during a nonstress test. Choice B is incorrect as fasting is not required before this test. Choice D is incorrect as a full bladder is not necessary for a nonstress test.
