1. A male client recently started taking Haloperidol. Which of the following findings is the highest priority to report to the provider?
- A. Shuffling gait
- B. Neck spasms
- C. Drowsiness
- D. Impotence
Correct answer: B
Rationale: Neck spasms are an indication of acute dystonia, a serious side effect of Haloperidol that can quickly progress to a crisis situation. Immediate medical attention is necessary to prevent complications. Shuffling gait and drowsiness are common side effects of Haloperidol but are not as urgent as neck spasms. Impotence is not typically associated with Haloperidol use. Therefore, identifying neck spasms as the priority finding is crucial for the client's safety.
2. A client has a new prescription for Valsartan. Which of the following adverse effects should the nurse monitor?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Bradycardia
- D. Hypercalcemia
Correct answer: A
Rationale: Corrected Rationale: Valsartan is an angiotensin II receptor blocker (ARB) that can cause hyperkalemia by affecting the renin-angiotensin-aldosterone system. The nurse should closely monitor the client's potassium levels due to the risk of hyperkalemia, which can lead to serious cardiac complications. Choice B, hypoglycemia, is not a common adverse effect of Valsartan. Choice C, bradycardia, is not directly associated with Valsartan use. Choice D, hypercalcemia, is not a typical adverse effect of Valsartan.
3. A healthcare professional is preparing to administer IV Dantrolene to a client who has developed Malignant Hyperthermia during surgery. Which of the following actions should the healthcare professional take?
- A. Dilute the medication with sterile water and administer it rapidly.
- B. Store the medication in a refrigerator until use.
- C. Administer the medication through a large-bore IV catheter.
- D. Administer the medication via an infusion pump over 60 minutes.
Correct answer: C
Rationale: Dantrolene should be administered through a large-bore IV catheter because it is highly irritating to tissues and can cause vein irritation or thrombophlebitis if administered through a small vein. Using a large-bore IV catheter helps to minimize the risk of tissue damage and ensures proper and safe administration of the medication in emergency situations like Malignant Hyperthermia. Choices A, B, and D are incorrect because diluting the medication with sterile water and administering it rapidly can lead to tissue damage, storing the medication in a refrigerator is not necessary, and administering the medication via an infusion pump over 60 minutes is not appropriate in emergency situations like Malignant Hyperthermia where rapid administration is crucial.
4. A client has a new prescription for Digoxin for heart failure. Which of the following adverse effects should the client be instructed to monitor for and report to the provider?
- A. Dry cough
- B. Pedal edema
- C. Bruising
- D. Yellow-tinged vision
Correct answer: D
Rationale: Yellow-tinged vision is a potential adverse effect of digoxin, which may indicate toxicity. It is crucial for the client to report this symptom promptly to the healthcare provider to prevent any further complications. Dry cough is not typically associated with digoxin use. Pedal edema is a common symptom of heart failure, which digoxin is prescribed to manage. Bruising is not a common adverse effect of digoxin.
5. While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. PT
- B. INR
- C. aPTT
- D. Platelet count
Correct answer: C
Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation. Choices A, B, and D are incorrect. PT (Prothrombin Time) and INR (International Normalized Ratio) are used to monitor Warfarin therapy, not Heparin. Platelet count is important in assessing for thrombocytopenia but is not a specific indicator of Heparin therapy effectiveness.
