1. A drug ending in the suffix (tidine) is considered a ______.
- A. Antidepressant
- B. Protease inhibitor
- C. Beta antagonist
- D. H antagonist
Correct answer: D
Rationale: Drugs ending in -tidine are histamine (H2) receptor antagonists, which block the action of histamine at the H2 receptors, commonly used to reduce stomach acid production. Therefore, the correct answer is an 'H antagonist.' It is essential to be familiar with drug suffixes as they can provide clues to the drug's class and function.
2. A client has a new prescription for Atenolol. Which of the following statements should be included by the healthcare provider?
- A. Take the medication with a high-fat meal.
- B. Monitor your heart rate before taking the medication.
- C. Expect a persistent cough.
- D. Avoid foods high in fiber.
Correct answer: B
Rationale: When a client is prescribed Atenolol, a beta-blocker, they should monitor their heart rate before taking the medication. It is crucial because if the heart rate is below 60 bpm, the client needs to contact their healthcare provider for further guidance and evaluation. Choices A, C, and D are incorrect. Atenolol does not need to be taken with a high-fat meal, does not typically cause a persistent cough, and there is no need to avoid foods high in fiber when taking this medication.
3. Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?
- A. Heparin
- B. Alprazolam
- C. Digoxin
- D. Levothyroxine
Correct answer: C
Rationale: Digoxin is the correct answer. It is a medication known for its positive inotropic effects, which increase cardiac output, and negative chronotropic effects, which slow the heart rate. These effects are achieved by inhibiting the sodium-potassium ATPase pump in myocardial cells. Therefore, Digoxin is commonly prescribed to manage conditions like heart failure and atrial fibrillation, where enhancing cardiac output and reducing heart rate are beneficial. Choices A, B, and D are incorrect because Heparin is an anticoagulant, Alprazolam is a benzodiazepine used for anxiety disorders, and Levothyroxine is a thyroid hormone replacement drug, none of which have the specified therapeutic effects on cardiac function.
4. A client is undergoing preparation for extensive colorectal surgery. Which of the following oral antibiotics should be administered to suppress normal flora in the GI tract?
- A. Kanamycin
- B. Gentamicin
- C. Neomycin
- D. Tobramycin
Correct answer: C
Rationale: The correct answer is C: Neomycin. Neomycin, an aminoglycoside antibiotic, is administered orally before GI surgery to eliminate the normal flora in the large intestine. This helps reduce the risk of postoperative infections by decreasing the bacterial load in the gut. Choices A, B, and D (Kanamycin, Gentamicin, Tobramycin) are not typically used to suppress normal flora in the GI tract before colorectal surgery.
5. A client is receiving daily doses of Oprelvekin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of this medication?
- A. Hemoglobin
- B. Absolute neutrophil count
- C. Platelet count
- D. Total white blood cell count
Correct answer: C
Rationale: The nurse should monitor the platelet count to determine the effectiveness of Oprelvekin. The expected outcome for this medication is a platelet count greater than 50,000/mm^3. Oprelvekin is a medication used to stimulate platelet production, making platelet count a crucial parameter to assess its effectiveness. Monitoring hemoglobin, absolute neutrophil count, or total white blood cell count is not specifically related to the action or effectiveness of Oprelvekin.
