A nurse is preparing to administer doxycycline 100 mg PO every 12 hr to a client. Available is doxycycline 50 mg/tablet. How many tablets should the nurse administer in a 24-hr period? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["4"]

Calculation:

  • Dose: 100 mg every 12 hours → 2 doses per 24 hours

  • Each dose: 100 mg

  • Available: 50 mg/tablet

  • Tablets per dose: 100 ÷ 50 = 2 tablets

  • Tablets per 24 hrs: 2 doses × 2 tablets = 4 tablets

Correct Answer is {"dropdown-group-1":"F","dropdown-group-2":"D"}

Explanation

The nurse should first address the client's pelvic ultrasound, followed by the client's quantitative beta-hCG.

Pelvic ultrasound is urgent to evaluate for possible ectopic pregnancy, especially given:

  • Positive urine and abnormally low progesterone
  • Discrepant and confusing hCG levels
  • Right lower quadrant tenderness, spotting, and history of PID—all red flags for ectopic.

Quantitative beta-hCG interpretation becomes meaningful after imaging; it supports or confirms what the ultrasound suggests (e.g., nonviable pregnancy, ectopic gestation).
