Question 1 of 5
A client presents to the healthcare setting with a diagnosis of emphysema. Which of the following medications would be contraindicated with the client's allergy to soybeans?
Correct Answer: A
Rationale: Ipratropium bromide (Atrovent) is an anticholinergic bronchodilator often used to treat chronic obstructive pulmonary disease (COP
D), including emphysema. However, it contains soy lecithin, which can cause allergic reactions in individuals with soy allergies.
Question 2 of 5
A nurse is assessing a client who has been taking sertraline (Zoloft) for 2 weeks. The nurse should identify which of the following findings as an indication that the medication is effective?
Correct Answer: C
Rationale: An increase in mood is a direct indication that sertraline is effective. Sertraline is a selective serotonin reuptake inhibitor (SSRI) used to treat depression, anxiety, and other mood disorders by increasing serotonin levels in the brain.
Question 3 of 5
A nurse is preparing to administer gabapentin 900 mg PO once daily for a client who has neuropathic pain. The amount available is gabapentin 300 mg/capsule. How many capsules should the nurse administer per dose?
Correct Answer: 3
Rationale: Divide the prescribed dose (900 mg) by the available strength (300 mg/capsule). Result: 3 capsules are needed per dose.
Question 4 of 5
A client presents to the clinic with intense itching at night and is diagnosed with Pinworms. The nurse anticipates the client would be placed on which medication to treat this condition?
Correct Answer: C
Rationale: Mebendazole (Vermox) is an anthelmintic medication specifically used to treat parasitic worm infections, including pinworms. It works by inhibiting the worms' ability to absorb glucose, leading to their death.
Question 5 of 5
A nurse is caring for a client with an elevated serum potassium level of 6.0 mEq/L (3.5-5.0 mEq/L). Which scheduled medication should the nurse plan to administer?
Correct Answer: D
Rationale: Sodium polystyrene sulfonate is a cation-exchange resin that is specifically used to treat hyperkalemia. It works by binding to potassium in the gastrointestinal tract, which is then excreted through the feces. This process effectively lowers serum potassium levels. Given its mechanism of action and its specific indication for treating hyperkalemia, sodium polystyrene sulfonate is the appropriate choice for a patient with an elevated potassium level of 6.0 mEq/L.
