Question 1 of 5
A healthcare professional is reviewing laboratory findings and notes that a client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the healthcare professional?
Correct Answer: A
Rationale: In this scenario, the correct answer is "A) Perform immediate gastric lavage." This action is appropriate because a plasma Lithium level of 2.1 mEq/L is considered toxic, as the therapeutic range is typically 0.6-1.2 mEq/L. Gastric lavage is a common method used to reduce further absorption of the drug in cases of acute lithium toxicity. It involves flushing the stomach with a solution to remove any remaining lithium. Option B) Prepare the client for hemodialysis is incorrect because while hemodialysis may be necessary in severe cases of lithium toxicity, it is not the initial intervention. Gastric lavage is typically the first step in managing acute lithium toxicity. Option C) Administer an additional oral dose of lithium is incorrect as it would worsen the toxicity and increase the plasma level further, leading to more severe symptoms. Option D) Request a stat repeat of the laboratory test is incorrect because action needs to be taken promptly to address the toxic levels of lithium in the client's system. Waiting for a repeat test would delay necessary intervention. In an educational context, this question highlights the critical importance of recognizing and managing drug toxicities promptly and effectively. Understanding the appropriate interventions for specific toxicities, like lithium toxicity, is essential for healthcare professionals to ensure patient safety and optimal outcomes.
Question 2 of 5
A healthcare provider is teaching the parents of a school-age child about transdermal Methylphenidate. Which of the following instructions should the healthcare provider include?
Correct Answer: B
Rationale: When administering transdermal Methylphenidate, it is important to leave the patch on for 9 hours each day to ensure the medication is effective. This duration allows for proper absorption of the medication through the skin. It is crucial for parents to follow this instruction to achieve the desired therapeutic effect for their child.
Question 3 of 5
A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and has muscle weakness. The nurse should anticipate a prescription for which of the following medications?
Correct Answer: A
Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers, such as the one the client received. It works by inhibiting the breakdown of acetylcholine, thereby enhancing neuromuscular transmission and reversing muscle weakness caused by the neuromuscular blocking agent.
Question 4 of 5
A healthcare provider is reviewing a client's health record and notes that the client is experiencing episodes of hypokalemia. Which of the following medications should the healthcare provider identify as a cause of the client's hypokalemia?
Correct Answer: C
Rationale: Furosemide is a loop diuretic that acts on the kidneys to increase urine production. This increased urine output can lead to the excessive excretion of potassium, resulting in hypokalemia. Monitoring potassium levels and considering supplementation may be necessary when a patient is on furosemide to prevent or manage hypokalemia.
Question 5 of 5
A client has a new prescription for Metoprolol to treat hypertension. Which of the following instructions should the nurse include?
Correct Answer: C
Rationale: The correct instruction for a client taking Metoprolol, a medication used to treat hypertension, is to avoid sudden changes in position. Metoprolol can cause orthostatic hypotension, a sudden drop in blood pressure when moving from lying down to standing up, leading to dizziness and falls. By advising the client to change positions slowly, the nurse helps prevent these adverse effects and promotes safety.
