The nurse prepares to administer lithium, a mood stabilizing drug, to a patient. Which laboratory result should first be assessed?

Serum creatinine

Serum troponin I and T levels

Fasting blood glucose level

Serum lipid profile

Answer and Explanation

The Correct Answer is A

Choice A rationale: Before administering lithium, the nurse should assess serum creatinine levels. Lithium is excreted by the kidneys, and impaired renal function can lead to lithium toxicity.
Choice B rationale: Serum troponin I and T levels are markers of cardiac damage and are not directly related to lithium therapy.
Choice C rationale: Fasting blood glucose level is not specifically related to the assessment needed before administering lithium.
Choice D rationale: Serum lipid profile is not directly related to the assessment needed before administering lithium.

Correct Answer is A

Explanation

Choice A rationale: Propofol is formulated in a lipid emulsion that can increase the serum triglyceride levels and cause pancreatitis, especially in patients with preexisting hyperlipidemia.
Choice B rationale: History of hyperlipidemia is not typically associated with an increased risk of adverse effects with propofol infusion.
Choice C rationale: History of breast cancer is not directly associated with an increased risk of adverse effects with propofol infusion.
Choice D rationale: History of arthritis is not directly associated with an increased risk of adverse effects with propofol infusion.

A. Administer the medication when the patient has an empty stomach. B. Instruct the patient to avoid high-protein foods. C. Have the patient increase the intake of vitamin B6. D. Discontinue the drug for 10 days (for a "drug holiday").

Correct Answer is B

Explanation

Choice A rationale: Administering the medication with an empty stomach may enhance absorption but is not the best strategy for addressing "on-off" episodes.
Choice B rationale: The correct answer. High-protein foods can interfere with the absorption of levodopa, leading to "on-off" episodes.
Choice C rationale: Vitamin B6 supplementation is not typically used to address "on- off" episodes associated with levodopa/carbidopa.
Choice D rationale: Discontinuing the drug for 10 days (a "drug holiday") is not recommended and may result in a worsening of symptoms.
