ATI Capstone Pharmacology Assessment 1
1. A nurse is preparing to administer an intramuscular injection to an adult client. At what angle should the nurse administer the medication using the ventrogluteal site?
- A. a 45-degree angle
- B. a 60-degree angle
- C. a 75-degree angle
- D. a 90-degree angle
Correct answer: D
Rationale: Intramuscular injections in the ventrogluteal site should be administered at a 90-degree angle. This angle ensures that the medication reaches the muscle tissue effectively. Angles less than 90 degrees can cause subcutaneous injection instead of intramuscular, leading to slower absorption of the medication. Angles greater than 90 degrees risk hitting bone or nerves, causing unnecessary pain or injury. Therefore, the correct angle for administering intramuscular injections in the ventrogluteal site is 90 degrees.
2. A nurse is caring for a client receiving theophylline for chronic obstructive pulmonary disease (COPD). Which of the following client findings indicates the need for immediate intervention?
- A. Productive cough
- B. Drowsiness
- C. Vomiting
- D. Polyuria
Correct answer: D
Rationale: Polyuria is a sign of theophylline toxicity and requires immediate intervention. Theophylline toxicity can lead to serious complications, and polyuria is a concerning symptom that indicates the need for urgent medical attention. Productive cough, drowsiness, and vomiting are common side effects of theophylline but are not typically indicative of immediate life-threatening issues like polyuria in the context of theophylline toxicity.
3. A nurse is caring for a client taking ciprofloxacin for an infection. Which of the following adverse effects should the nurse include in the client education?
- A. Constipation
- B. Tendon rupture
- C. Dry mouth
- D. Nasal congestion
Correct answer: B
Rationale: The correct answer is B: Tendon rupture. Ciprofloxacin belongs to the fluoroquinolone class of antibiotics, which is associated with the adverse effect of tendon rupture. Tendon rupture is a severe but rare side effect that can occur with the use of ciprofloxacin. Educating the client about this potential adverse effect is crucial to promote awareness and early recognition of symptoms, such as tendon pain, swelling, or inflammation. Choices A, C, and D are not typically associated with ciprofloxacin use and are less relevant for client education in this scenario.
4. A nurse is caring for a client who is prescribed warfarin. Which of the following laboratory tests should the nurse review to evaluate the therapeutic effect of this medication?
- A. aPTT
- B. INR
- C. Serum glucose
- D. Bilirubin
Correct answer: B
Rationale: The correct answer is B: INR. The International Normalized Ratio (INR) is the most reliable test for evaluating the therapeutic effects of warfarin therapy. INR measures the clotting ability of the blood and helps determine if the dosage of warfarin is within the therapeutic range. Choice A, aPTT, is not typically used to monitor the effects of warfarin. Choice C, Serum glucose, and choice D, Bilirubin, are not relevant to monitoring the therapeutic effect of warfarin.
5. A client with an artificial heart valve is prescribed warfarin therapy. Which of the following laboratory values should the nurse monitor to assess the therapeutic effect of warfarin?
- A. Hemoglobin (Hgb)
- B. Prothrombin time (PT)
- C. Bleeding time
- D. Activated partial thromboplastin time (aPTT)
Correct answer: B
Rationale: The correct answer is B: Prothrombin time (PT). Warfarin is an anticoagulant medication that works by inhibiting the clotting factors dependent on vitamin K, such as factors II, VII, IX, and X. The prothrombin time (PT) measures the extrinsic pathway and is used to monitor the therapeutic effects of warfarin therapy. Monitoring PT helps assess the time it takes for the blood to clot, ensuring that the anticoagulant effect is within the desired range. Choices A, C, and D are incorrect because hemoglobin (Hgb) measures the amount of hemoglobin in the blood, bleeding time assesses the time it takes for bleeding to stop, and activated partial thromboplastin time (aPTT) is used to monitor heparin therapy, not warfarin therapy.
