Question 1 of 5
What is a severe adverse effect of warfarin?
Correct Answer: A
Rationale: Warfarin is an anticoagulant medication commonly used to prevent blood clots. One of the most severe adverse effects of warfarin is the risk of bleeding. This can occur in various parts of the body, such as the gastrointestinal tract, brain, or other organs. Bleeding complications can range from minor bruising to life-threatening hemorrhages, especially if warfarin levels are not properly monitored. Patients taking warfarin should be closely monitored for signs of bleeding, and their medication dosages should be adjusted as needed to maintain a balance between preventing clotting and avoiding excessive bleeding.
Question 2 of 5
Which of the following procedures does NOT result in local analgesia:
Correct Answer: A
Rationale: Increasing the temperature does not result in local analgesia. In fact, higher temperatures can often lead to increased pain sensitivity. Local analgesia is achieved through methods such as chemically or physically damaging nerve trunks, stimulating large fiber nerve activity, or rendering tissue anemic. These procedures work by interrupting the transmission of pain signals to the brain or by reducing the sensitivity of local nerve endings to pain stimuli.
Question 3 of 5
Which of the following best describes H1 receptor antagonist:
Correct Answer: D
Rationale: H1 receptor antagonists are primarily used for the treatment and prevention of allergic reactions. They work by blocking the H1 receptors, which are responsible for mediating allergic responses such as itching, swelling, and inflammation. This action helps to alleviate symptoms of allergies like sneezing, itching, and runny nose.
Question 4 of 5
The nurse is performing a health history on a patient who is ordered to begin therapy with valproic
Correct Answer: D
Rationale: Valproic acid is metabolized in the liver, and patients with liver disease may have impaired liver function, which can lead to reduced metabolism of the drug and potential toxicity. Therefore, a patient with a history of liver disease starting therapy with valproic acid would be a cause for concern for the nurse. Monitoring of liver function tests would be crucial in this patient population to ensure the medication is being safely metabolized.
Question 5 of 5
A priority nursing assessment for a patient who is to receive an alpha- or beta-adrenergic blocking agent would be what?
Correct Answer: D
Rationale: The most serious adverse effect would be severe bradycardia, so the nurse’s priority would be assessing the heart rate. If the patient were identified as having diabetes, then monitoring blood glucose levels would become important because these drugs can aggravate diabetes by blocking sympathetic response including masking the usual signs and symptoms of hypoglycemia and hyperglycemia. Respiratory rate could be impacted if the patient was identified as having a condition causing bronchospasm and diabetes because the combination could worsen both conditions. Measuring urine output should be part of the patient’s care, but it is not the priority assessment.
