Question 1 of 5
An elderly patient has been taking 80 mg of furosemide (Lasix) bid. The nurse notes that the patient's most recent potassium level is 2.5mEq/L. The nurse should:
Correct Answer: D
Rationale: A potassium level of 2.5 mEq/L indicates hypokalemia, a serious side effect of furosemide, a potassium-wasting diuretic. The nurse should withhold the medication and notify the physician to address the electrolyte imbalance.
Question 2 of 5
The nurse is teaching a client with a history of hyperlipidemia about dietary modifications. The nurse should tell the client to avoid:
Correct Answer: A
Rationale: Saturated fats increase LDL cholesterol, worsening hyperlipidemia, so they should be avoided to reduce cardiovascular risk.
Question 3 of 5
Which complaint is frequently expressed by a client with macular degeneration?
Correct Answer: A
Rationale: Macular degeneration affects central vision, impairing activities like sewing or reading that require focused vision. Severe pain with nausea is typical of acute glaucoma, halos suggest cataracts or glaucoma, and veil-like vision loss is more associated with retinal detachment.
Question 4 of 5
A 14-year-old boy has had diabetes for 7 years. He takes 30 U of NPH insulin and 10 U of regular insulin every morning at 7 AM. He eats breakfast at 7:30 AM and lunch at noon. What time should he expect the greatest risk for hypoglycemia?
Correct Answer: C
Rationale: This time is incorrect because regular insulin would peak after the teenager has eaten breakfast. This time is incorrect because it is after lunch when the NPH peaks. Regular insulin peaks in 2-3 hours and has a duration of 4-6 hours. NPH insulin's onset is 4-6 hours and peaks in 8-16 hours. Blood sugar would peak after meals and be lowest before meals and during the night. This time is incorrect because it is before the NPH and after the regular insulin peak times.
Question 5 of 5
The client is admitted with a diagnosis of vasa previa. Which delivery method is most likely to be planned?
Correct Answer: B
Rationale: Vasa previa with fetal vessels crossing the cervical os requires cesarean section to prevent vessel rupture and fetal exsanguination during vaginal delivery. Forceps or vacuum delivery increases risk.
