Question 1 of 5
The hospitalized child who has a blood lead level of 50 mcg/dL is to receive succimer 10 mg/kg oral capsule q8h for 5 days. The child weighs 20 kg. Which intervention by the student nurse should be corrected by the observing nurse?
Correct Answer: A
Rationale: A: The 20-kg child should receive two capsules of succimer (Chemet), not one. Dose (mg) = 20 kg x 10 mg/kg = 200 mg. B: Succimer capsules can be opened and sprinkled on a small amount of food or in liquid to be swallowed; two 100-mg capsules = 200 mg, which is the correct dose. C: Fluids should be increased to prevent renal damage because succimer is excreted by the kidneys. D: Succimer forms a water-soluble compound with lead, allowing urinary elimination of excessive amounts of lead. Lead is removed from the blood, and theoretically some lead is removed from tissues and organs.
Question 2 of 5
The LPN is taking care of a client with a documented allergy to Penicillin. After rounds, the PN notices that the client has an order for Cefazolin. Which of the following actions would be the least appropriate?
Correct Answer: C
Rationale: The LPN should clarify the order with the care team prior to determining the medication should not be given. Even though the client may have a potential reaction due to the Penicillin allergy, the therapeutic benefits of the antibiotic may outweigh the allergic reaction.
Question 3 of 5
The client with CRF is receiving epoetin alfa. Which finding should indicate to the nurse that the action of the medication has been effective?
Correct Answer: B
Rationale: A: Epoetin alfa does not have an effect on urine output or BP. B: Epoetin alfa stimulates erythropoiesis, or the production of RBCs. It is used in treating anemias associated with decreased RBC production, such as in renal failure. Hgb and Hct are used to evaluate the medication's effectiveness. The target Hgb for the client with CRF is 12 g/dL. C: Epoetin alfa does not have an effect on BP or HR. D: The client may report increased energy and less fatigue because of the increased Hgb levels, but these findings are not used to evaluate the medication's action.
Question 4 of 5
The factor that most determines drug distribution is:
Correct Answer: A
