The healthcare provider is monitoring a client receiving lidocaine IV. What side effect is the healthcare provider most concerned about?

Correct Answer: C

Rationale: The correct answer is C: Seizures. Lidocaine is a local anesthetic that can cause central nervous system toxicity, leading to seizures. This is the most concerning side effect because it can be life-threatening. Severe headache (A) is not typically associated with lidocaine toxicity. Nausea and vomiting (B) are common side effects but not the most concerning. Tremors (D) can occur but are not as serious as seizures in this context.

Correct Answer: B

Rationale: The correct answer is B: Check the client's blood pressure. When administering a beta blocker to a client with hypertension, the priority assessment is to check the client's blood pressure. Beta blockers lower blood pressure, so monitoring it before administration helps ensure it is within the safe range. Checking the client's heart rate (choice A) is important but not the priority in this scenario. Respiratory rate (choice C) and temperature (choice D) are not directly related to the administration of beta blockers for hypertension.

Correct Answer: A

Rationale: The correct answer is A: Foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium. Consuming foods high in potassium while on spironolactone can lead to hyperkalemia, which is an elevated level of potassium in the blood. This can result in serious health complications such as irregular heartbeats and muscle weakness. Therefore, it is crucial for clients on spironolactone to avoid foods high in potassium to prevent these adverse effects. Choices B, C, and D are incorrect because spironolactone does not specifically interact with sodium, calcium, or chloride in a way that necessitates avoiding foods high in these electrolytes.

Correct Answer: A

Rationale: The correct answer is A: Platelet count. Enoxaparin is an anticoagulant that works by preventing blood clots. Monitoring platelet count is crucial to assess for potential thrombocytopenia, a side effect of enoxaparin that can increase the risk of bleeding. Hemoglobin (B) and White blood cell count (C) are not directly affected by enoxaparin. aPTT (D) is not the most important lab value to monitor as enoxaparin does not directly affect this clotting parameter.

Correct Answer: D

Rationale: The correct answer is D: Decreases blood pressure. Calcium channel blockers inhibit the influx of calcium into cardiac and smooth muscle cells, leading to vasodilation and decreased peripheral resistance, ultimately reducing blood pressure. This effect is beneficial in conditions such as hypertension and angina. The other choices are incorrect because calcium channel blockers typically do not directly affect heart rate or increase blood pressure.
