A patient receiving IV potassium chloride (KCl) complains of burning at the IV site. What is the nurse's priority action?
Answer: Slow the infusion rate and apply a warm compress
IV potassium frequently causes burning due to its irritant nature; slowing the infusion and applying warmth can reduce discomfort without stopping therapy.
A patient prescribed methotrexate for rheumatoid arthritis should receive which supplement to reduce side effects?
Answer: Folic acid
Folic acid supplementation reduces methotrexate-induced side effects such as mucositis and bone marrow suppression by replenishing folate stores.
A patient with a new prescription for nitroglycerin sublingual tablets asks how to store them properly. What should the nurse teach?
Answer: Keep in the original dark glass bottle away from heat and light
Nitroglycerin degrades rapidly when exposed to heat, light, moisture, or plastic; it must be stored in the original dark glass bottle.
Which medication should be kept at the bedside when a patient is receiving IV magnesium sulfate for eclampsia?
Answer: Calcium gluconate
Calcium gluconate is the antidote for magnesium toxicity and should be immediately available at the bedside during IV magnesium infusions.
A patient prescribed ciprofloxacin for a urinary tract infection should be instructed to avoid which substance?
Answer: Antacids containing aluminum or magnesium
Antacids containing aluminum or magnesium bind to ciprofloxacin in the GI tract, reducing its absorption and therapeutic effectiveness.
A patient taking SSRIs for depression is also started on tramadol for pain. What risk should the nurse monitor for?
Answer: Serotonin syndrome
Combining SSRIs with tramadol (which also increases serotonin) can cause serotonin syndrome, a life-threatening condition.
Which finding requires the nurse to hold a scheduled dose of amlodipine (Norvasc) and contact the provider?
Answer: Blood pressure of 82/54 mmHg
Amlodipine is a calcium channel blocker that lowers blood pressure; a BP of 82/54 mmHg indicates hypotension, requiring the dose to be held.
