Question 1 of 5
Which of the following findings would necessitate discontinuing an IV potassium infusion in an adult with ketoacidosis?
Correct Answer: A
Rationale: Adequate renal flow of 30 mL/hr is a necessity with potassium infusions because potassium is excreted renally. Because potassium level will decrease during correction of diabetic ketoacidosis, potassium will be infused even if plasma levels of potassium are normal. A small T wave is normal and desired on the electrocardiogram. A tall, peaked T-wave could indicate overinfusion of potassium and hyperkalemia. Glucose levels of <200 are desirable.
Question 2 of 5
A client is taught to eat foods high in potassium. Which food choices would indicate that this teaching has been successful?
Correct Answer: A
Rationale: Acorn squash and brussels sprouts are potassium-rich, indicating successful teaching. The other options contain fewer potassium-rich foods.
Question 3 of 5
A female client has been hospitalized for several months following major abdominal surgery for a ruptured colon. A colostomy was created, and the large abdominal wound was left open and allowed to heal through granulation. She is receiving gentamicin IV for treatment of wound infection. Knowing this drug is ototoxic, the nurse would implement which of the following measures?
Correct Answer: A
Rationale: The first nursing measure is to instruct the client in which drug side effects to report. Discontinuing the drug is not an independent nursing intervention and may compromise client care. Audiometric testing will detect hearing loss, but it does not indicate a potential cause. Equalizing middle ear pressure will not prevent hearing loss.
Question 4 of 5
Which information should be given to the client using a TENS unit?
Correct Answer: B
Rationale: Prolonged use of a TENS unit can cause skin irritation due to electrode adhesion or electrical stimulation. Electrocution is not a risk with battery-operated units, placement requires specific guidance, and lotions may interfere with electrode contact.
Question 5 of 5
The client is admitted with a diagnosis of molar pregnancy. Which symptom is most likely to be present?
Correct Answer: A
Rationale: Molar pregnancy (hydatidiform mole) often causes severe nausea and vomiting due to high levels of human chorionic gonadotropin (hCG). The uterus is typically larger than expected and fetal heart tones are absent as there is no viable fetus.
