Question 1 of 5
The wife of a client with paranoid schizophrenia tells the nurse, 'I’ve learned that my husband has several close relatives with the same disorder. Does this problem run in families?' The response based on recent discoveries in the field of genetics would be:
Correct Answer: B
Rationale: The correct answer is B because recent research has indeed identified a gene linked to schizophrenia, indicating a genetic component in the disorder. This response acknowledges the genetic basis of schizophrenia and provides an accurate and up-to-date explanation. Other choices are incorrect: A dismisses the genetic link, C jumps to discussing the children without addressing the genetic aspect, and D is false as both schizophrenia and bipolar disorder have genetic components.
Question 2 of 5
When administering digoxin immune Fab (Digibind) to a patient with severe digoxin toxicity, the nurse knows that each vial can bind with how much digoxin?
Correct Answer: A
Rationale: The correct answer is A: 0.5 mg. Digoxin immune Fab binds to digoxin in a 1:1 ratio, meaning each vial can bind with 0.5 mg of digoxin. This is crucial in the treatment of severe digoxin toxicity as it helps to neutralize the toxic effects of digoxin. Choices B, C, and D are incorrect because they do not reflect the 1:1 binding ratio between digoxin immune Fab and digoxin, which is essential in determining the appropriate dose needed for effective treatment.
Question 3 of 5
During a routine checkup, a patient states that she is unable to take the prescribed antihistamine because of one of its most common adverse effects. The nurse suspects that which adverse effect has been bothering this patient?
Correct Answer: C
Rationale: The correct answer is C: Drowsiness. Antihistamines are known to cause drowsiness as a common adverse effect due to their sedative properties. This is why the patient may be unable to take the medication. Choices A, B, and D are incorrect because constipation and abdominal cramps are not common adverse effects of antihistamines, and decreased libido is not typically associated with this type of medication.
Question 4 of 5
Pick out the appropriate alimentary route of administration when passage of drugs through liver is minimized:
Correct Answer: C
Rationale: Rationale: 1. Rectal administration bypasses the liver initially, reducing first-pass metabolism. 2. Oral administration (Option A) passes through the liver first, increasing metabolism. 3. Transdermal administration (Option B) bypasses the liver but is not as effective in minimizing liver metabolism as rectal. 4. Intraduodenal administration (Option D) directly enters the small intestine, interacting with the liver. Therefore, rectal administration is the appropriate route to minimize liver metabolism.
Question 5 of 5
Give the definition for a therapeutical dose:
Correct Answer: C
Rationale: The therapeutical dose is the amount of a substance required to produce the desired effect in most patients. This is because it aims to provide optimal benefits with minimal side effects. Choice A is incorrect as it refers to a subtherapeutic dose. Choice B is incorrect as it describes a toxic dose. Choice D is incorrect as it does not accurately define a therapeutical dose.
