Cardiovascular System Practice Exam
1. Which medication relaxes the muscles around the airways, making it easier to breathe?
- A. Bronchodilator
- B. Corticosteroid
- C. Antihistamine
- D. Mucolytic
Correct answer: A
Rationale: The correct answer is A, Bronchodilator. Bronchodilators are medications that relax the muscles surrounding the airways, which helps to open them and makes breathing easier. Corticosteroids (choice B) work by reducing inflammation, antihistamines (choice C) are used to manage allergies, and mucolytics (choice D) help to break down and thin mucus in the airways.
2. Surgery is performed on a child to correct cryptorchidism. The parents understand the reason for the surgery if they tell the nurse this was done to do what?
- A. Prevent damage to the undescended testicle.
- B. Prevent urinary tract infections.
- C. Prevent prostate cancer.
- D. Prevent an inguinal hernia.
Correct answer: A
Rationale: The primary reason for correcting cryptorchidism through surgery is to prevent damage to the undescended testicle, which can lead to infertility and increase the risk of testicular cancer. Prevention of UTIs and prostate cancer are not the primary concerns in this context.
3. A client takes atorvastatin (Lipitor), with laboratory results showing a blood urea nitrogen (BUN) of 33 mg/dL and creatinine of 2.8 mg/dL. What action by the nurse is best?
- A. Ask if the client eats grapefruit.
- B. Assess the client for dehydration.
- C. Facilitate admission to the hospital.
- D. Obtain a random urinalysis.
Correct answer: A
Rationale: There is a drug-food interaction between statins and grapefruit that can lead to acute kidney failure. The client has elevated renal laboratory results, indicating kidney involvement. The nurse should ask if the client consumes grapefruit or grapefruit juice. While dehydration can elevate BUN, the increase in creatinine is more specific for kidney injury.
4. A client has been prescribed bupropion (Wellbutrin) for depression. Which instruction should the nurse provide during discharge?
- A. Take the medication with a full glass of water.
- B. Stop taking the medication if you feel better.
- C. Avoid drinking alcohol while taking this medication.
- D. Double the dose if you miss a dose.
Correct answer: C
Rationale: The correct instruction for the nurse to provide is to advise the client to avoid drinking alcohol while taking bupropion (Wellbutrin) due to the increased risk of side effects like seizures. Alcohol can interact with bupropion and worsen its side effects, making it important to abstain from alcohol consumption during the treatment. Option A is incorrect because taking the medication with a full glass of water is a general instruction for medications and not specific to bupropion. Option B is incorrect as abruptly stopping bupropion can lead to withdrawal symptoms and should only be done under medical supervision. Option D is incorrect as doubling the dose of bupropion is dangerous and should not be done, even if a dose is missed.
5. An advance directive known as a durable power of attorney involves appointing another person called a(n) _____ to act as the decision maker in the event of the patient's incapacitation.
- A. witness
- B. primary caregiver
- C. health care agent
- D. state proxy
Correct answer: C
Rationale: The correct answer is 'health care agent.' A health care agent is appointed through a durable power of attorney to make medical decisions on behalf of a patient who becomes incapacitated. The term 'witness' (choice A) is incorrect because a witness only observes the signing of the directive and does not make decisions. 'Primary caregiver' (choice B) is also incorrect as they may provide care but are not necessarily legally empowered to make decisions. 'State proxy' (choice D) is not commonly used in the context of advance directives or health care decision making, making it an incorrect choice.
