Question 1 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 2 of 5
Dr. Smith orders a gram of human salt poor albumin product for a patient. The product is available in a 50-milliliter vial with a concentration of 25 percent. What dosage will the nurse administer?
Correct Answer: D
Rationale: A 25 percent albumin solution contains 25 grams of albumin per 100 milliliters. To administer 1 gram of albumin, the nurse would calculate the volume as follows: 1 gram ÷ 25 grams/100 milliliters = 4 milliliters. Therefore, the nurse will administer 4 milliliters of the 25 percent albumin solution to deliver the ordered dose of 1 gram. Using the entire vial or not using the product at all would be incorrect.
Question 3 of 5
Before administering Digoxin, the nurse should complete which task?
Correct Answer: B
Rationale: Before administering Digoxin, it is crucial for the nurse to count the patient's apical pulse for 1 minute. Digoxin is a medication commonly prescribed to manage heart conditions such as heart failure and certain irregular heartbeats. Since Digoxin works by helping the heart beat stronger and at a more normal rhythm, it is essential to monitor the patient's heart rate before administering the medication. Counting the apical pulse for 1 minute allows for an accurate assessment of the patient's baseline heart rate, which is crucial in determining whether it is safe to administer Digoxin. If the heart rate is too low (bradycardia), administering Digoxin could potentially cause further complications. Therefore, assessing the apical pulse beforehand is a critical step in ensuring the safe administration of Digoxin.
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 22-year-old man has taken an overdose of sleeping pills after learning that he did not receive the job he has recently been interviewed for. He is found by his roommate conscious but not able to completely follow commands. The roommate calls the local poison control center. Instructions are given to self-administer syrup of ipecac while waiting for the rescue squad to respond. This agent has a mechanism of action that involves which of the following?
Correct Answer: B
Rationale: Syrup of ipecac induces vomiting in overdose. It stimulates the chemotactic trigger zone in the medulla-prompting emesis. Gag reflex stimulation is secondary. Suppressing pressures , gag reflex , or motor cortex (E) don't apply. Though less used now, ipecac's CNS action expels pills, aiding this acute scenario, distinct from mechanical or suppressive effects.
