1. The nurse is informed during shift report that a client is experiencing occasional ventricular dysrhythmias. The nurse reviews the client's laboratory results, recalling that which electrolyte imbalance could be responsible for this development?
- A. Hypokalemia
- B. Hypernatremia
- C. Hypochloremia
- D. Hypercalcemia
Correct answer: A
Rationale: Hypokalemia, which is low potassium levels, can disrupt the normal electrical activity of the heart and lead to ventricular dysrhythmias. Potassium plays a crucial role in maintaining the heart's rhythm, and a deficiency can result in dangerous heart rhythm abnormalities. Hypernatremia (Choice B), which is high sodium levels, does not directly impact heart rhythm. Hypochloremia (Choice C), which is low chloride levels, is not typically associated with ventricular dysrhythmias. Hypercalcemia (Choice D), which is high calcium levels, is not a common cause of ventricular dysrhythmias.
2. A client with myocardial infarction (MI) has been transferred from the coronary care unit (CCU) to the general medical unit with cardiac monitoring via telemetry. The nurse assisting in caring for the client expects to note which type of activity prescribed?
- A. Strict bed rest for 24 hours
- B. Bathroom privileges and self-care activities
- C. Unrestricted activities because the client is monitored
- D. Unsupervised hallway ambulation with distances less than 200 feet
Correct answer: B
Rationale: After being transferred from the CCU to the general medical unit with cardiac monitoring, the client with MI is typically prescribed bathroom privileges and self-care activities. This approach allows for gradual recovery and mobility while still being closely monitored, promoting the client's overall well-being and independence. Choice A, strict bed rest for 24 hours, is too restrictive and not recommended for MI patients as it can lead to complications like deep vein thrombosis. Choice C, unrestricted activities, is also not appropriate as MI patients usually require monitoring and gradual re-introduction to activities. Choice D, unsupervised hallway ambulation with distances less than 200 feet, may be too strenuous for a client who just got transferred from the CCU and needs a more gradual approach to activity.
3. Before administering a calcium channel blocker to a client with hypertension, what parameter should the nurse check?
- A. Serum calcium level
- B. Apical pulse
- C. Blood pressure
- D. Respiratory rate
Correct answer: C
Rationale: Before administering a calcium channel blocker to a client with hypertension, the nurse should check the client's blood pressure. Calcium channel blockers are prescribed to lower blood pressure, so it is essential to assess the current blood pressure to ensure safe administration and monitor the medication's effectiveness. Checking the serum calcium level (Choice A) is not necessary before administering a calcium channel blocker, as it does not directly impact the drug's action. Monitoring the apical pulse (Choice B) is important for other types of medications like beta-blockers, not specifically for calcium channel blockers. Assessing the respiratory rate (Choice D) is not directly related to administering calcium channel blockers for hypertension.
4. A client with deep vein thrombosis (DVT) is receiving anticoagulant therapy. The nurse should reinforce with the client the importance of reporting which potential side effect?
- A. Nausea
- B. Headache
- C. Gingival bleeding
- D. Dizziness
Correct answer: C
Rationale: The correct answer is C, 'Gingival bleeding.' Gingival bleeding is a common side effect of anticoagulant therapy. Anticoagulants work by prolonging the time it takes for blood to clot, which can lead to bleeding issues, including gingival bleeding. Nausea, headache, and dizziness are not typically associated with anticoagulant therapy. Since bleeding, including gingival bleeding, can be a serious side effect that requires medical attention, the client should be educated on reporting it promptly to their healthcare provider.
5. The healthcare provider is caring for a client with hypertension who is receiving a beta blocker. The provider should monitor for which potential side effect?
- A. Tachycardia
- B. Bradycardia
- C. Hypertension
- D. Hyperglycemia
Correct answer: B
Rationale: Corrected Rationale: Beta blockers are medications that can cause bradycardia by slowing down the heart rate. It is essential to monitor for this side effect in clients receiving beta blockers, as it can lead to serious complications such as decreased cardiac output and hypotension. Choices A, C, and D are incorrect because beta blockers are not expected to cause tachycardia (fast heart rate), hypertension (high blood pressure), or hyperglycemia (high blood sugar levels).
