Question 1 of 5
The nurse is caring for a client who has a prescription for clarithromycin 7.5 mg/kg/day PO in 2 divided doses. The client weighs 78 lb. How many mL should the nurse administer for each dose? Record your answer using 1 decimal place.
Correct Answer: 7.5 mL/dose
Rationale: Client weight: 78 lb ÷ 2.2 = 35.45 kg. Dose: 7.5 mg/kg/day × 35.45 kg = 265.875 mg/day ÷ 2 doses = 132.9375 mg/dose. Clarithromycin is typically 250 mg/5 mL. Thus, 132.9375 mg × (5 mL/250 mg) = 2.65875 mL ≈ 2.7 mL/dose.
Question 2 of 5
An elderly man has just returned from the operating room where he spent several hours in lithotomy position during a perineal prostatectomy. Which assessment should the nurse make because the client was in lithotomy position during surgery?
Correct Answer: A
Rationale: Prolonged lithotomy position risks nerve compression and impaired circulation in the lower extremities, necessitating assessment of pulses, paresthesias, and pain to detect complications like compartment syndrome.
Question 3 of 5
A client with metabolic acidosis associated with diabetes mellitus is admitted to the unit. A blood glucose of $250 \mathrm{mg} / \mathrm{dl}$ is present. Which symptom will most likely accompany ketoacidosis?
Correct Answer: B
Rationale: Diabetic ketoacidosis (DK
A) causes dehydration due to hyperglycemia, leading to polydipsia (excessive thirst). Oliguria may occur later, perspiration is not specific, and tremors are more associated with hypoglycemia.
Question 4 of 5
The nurse is preparing to give a heparin injection to a client who is severely malnourished and has minimal adipose tissue. Which method of injection would be appropriate for this client?
Correct Answer: C
Rationale: For a malnourished client with minimal adipose tissue, heparin should be injected at a 90-degree angle using a 25-gauge needle to ensure subcutaneous delivery without hitting muscle.
Question 5 of 5
Four clients arrive in the urgent care clinic. Which does the nurse anticipate to be the priority for intervention?
Correct Answer: A
Rationale: The child who is confused and irritable with missing glyburide pills suggests a potential hypoglycemic emergency due to sulfonylurea overdose, which requires immediate intervention to prevent severe complications like seizures or coma.
