ATI Pharmacology Proctored Exam
1. A client has a new prescription for Hydrochlorothiazide. Which of the following adverse effects should the nurse monitor?
- A. Hyponatremia
- B. Hyperkalemia
- C. Hypercalcemia
- D. Hypoglycemia
Correct answer: A
Rationale: Corrected Rationale: Hydrochlorothiazide, a diuretic, can lead to electrolyte imbalances, particularly hyponatremia (low sodium levels). The nurse should closely monitor the client's sodium levels due to the potential adverse effect of Hydrochlorothiazide. Incorrect Rationales: - Hyperkalemia (Choice B) is less likely to be caused by Hydrochlorothiazide; in fact, it can lead to hypokalemia. - Hypercalcemia (Choice C) is not a common adverse effect of Hydrochlorothiazide. - Hypoglycemia (Choice D) is not directly associated with Hydrochlorothiazide use.
2. What classification of drug is Penicillin?
- A. Antiarrhythmic
- B. Anticonvulsant
- C. Antibacterial
- D. Mood stabilizer
Correct answer: C
Rationale: Penicillin is classified as an antibacterial drug, specifically used to treat bacterial infections. It works by inhibiting the growth of bacteria, making it an effective treatment for various bacterial infections. Choices A, B, and D are incorrect as Penicillin does not belong to these drug classifications. Penicillin does not have any direct effect on heart rhythm (antiarrhythmic), does not treat seizures (anticonvulsant), and is not used to stabilize mood (mood stabilizer).
3. A healthcare professional is preparing to administer an IV bolus of Morphine to a client for pain management. Which of the following assessments is the healthcare professional's priority?
- A. Respiratory rate
- B. Pain level
- C. Blood pressure
- D. Level of consciousness
Correct answer: A
Rationale: The priority assessment for a client receiving an IV bolus of Morphine is the respiratory rate. Morphine can cause respiratory depression, which is a serious adverse effect. Monitoring the respiratory rate is crucial to detect any signs of respiratory compromise early and intervene promptly. Assessing pain level, blood pressure, and level of consciousness are also important but not the priority in this situation. Pain level can be assessed after ensuring the client's respiratory status is stable. Blood pressure and level of consciousness should be monitored but do not take precedence over the respiratory rate when administering Morphine.
4. A healthcare professional is reviewing laboratory results for a client who is receiving heparin via continuous IV infusion. Which of the following results indicates that the heparin infusion should be increased?
- A. aPTT of 90 seconds
- B. Platelet count of 150,000/mm³
- C. INR of 1.0
- D. Hgb of 15 g/dL
Correct answer: A
Rationale: An aPTT of 90 seconds is above the therapeutic range for heparin, which typically falls between 60-80 seconds. This indicates that the current heparin dose is too high, and the infusion rate should be decreased to avoid excessive anticoagulation and the risk of bleeding. Monitoring aPTT is crucial in adjusting heparin therapy to maintain it within the therapeutic range.
5. A client is starting therapy with filgrastim. Which of the following adverse effects should the nurse instruct the client to monitor?
- A. Bone pain
- B. Constipation
- C. Tinnitus
- D. Dry mouth
Correct answer: A
Rationale: When a client is starting therapy with filgrastim, monitoring for bone pain is essential. Filgrastim can lead to increased bone marrow activity, resulting in bone pain as a common adverse effect. Instructing the client to monitor and report any bone pain promptly can help in managing this side effect effectively.
