Question

A nurse reviews a medication order and finds that it is incomplete, lacking dosage information. What should the nurse do next

Answer 1

Correct Answers:

Contact the prescriber to obtain the missing dosage information before administering the medication.

Rationale :

🔹 The nurse must verify all components of a medication order, including dose, before administration to ensure safety and accuracy.

🔹 Administering a medication without a prescribed dose violates the “Right Dose” of medication administration.

🔹 Only the prescriber has legal authority to determine or change the drug dose, not the nurse.

🔹 Clarifying incomplete orders prevents medication errors, toxicity, and underdosing.

🔹 Contacting the prescriber ensures compliance with professional, legal, and institutional policies regarding safe medication administration.

Use clinical judgment to determine a dose

🔹 Nurses cannot prescribe medications.

🔹 Choosing a dose is outside the scope of practice and unsafe.

Administer a standard dose

🔹 “Standard dose” may be incorrect for this client’s age, weight, or condition.

🔹 Administering without an order is considered medication error.

Hold the medication and document

🔹 Holding without clarification delays treatment.

🔹 The priority action is to clarify, not simply withhold.

Answer 2

Correct Answers:

1 tsp

Rationale :

🔹 The ordered dose (12.5 mg) exactly matches the strength in 5 mL, so the client needs 5 mL.

🔹 1 teaspoon = 5 mL, making the dose equal to 1 tsp.

🔹 Using teaspoon units ensures accurate household measurement.

🔹 No rounding is needed because the result is a whole number.

🔹 This dose matches safe pediatric administration guidelines for diphenhydramine.

2 tsp

🔹 Would give 10 mL = 25 mg, double the intended dose.

🔹 Risk of sedation or toxicity.

12.5 tsp

🔹 Extremely inaccurate—this would be 62.5 mL, a dangerous overdose.

🔹 Not mathematically related to ordered dose.

Answer 3

Correct Answers:

Dosing should be based on the child's weight, and medications like acetaminophen can be given as needed.

Rationale :

🔹 Pediatric dosing is always based on mg/kg, ensuring safety and avoiding overdose.

🔹 Acetaminophen is appropriate for infants after vaccines when dosed correctly.

🔹 Infants do not have adult metabolism; improper dosing can cause organ toxicity.

🔹 Accurate weight-based dosing supports effective fever control without risk.

🔹 This response promotes safe parental medication practices, reducing medication errors.

Aspirin is safe

🔹 Aspirin is contraindicated for children due to Reye syndrome risk.

🔹 Dangerous for infants and NOT recommended.

Consult pediatrician before any fever medication

🔹 Caregivers can safely give acetaminophen for post-immunization fever without calling every time.

🔹 This delays simple and appropriate treatment.

Give adult doses

🔹 Infants have immature liver and kidney function, making adult doses unsafe.

🔹 Risk of severe overdose.

Answer 4

Correct Answers:

4.1

Rationale :

🔹 Weight must be converted from 29 lb → 13.2 kg for accurate mg/kg dosing.

🔹 Total daily dose = 50 mg × 13.2 kg = 660 mg/day.

🔹 q6h dosing divides into 4 equal doses → 165 mg per dose.

🔹 Using the concentration 200 mg/5 mL, the nurse calculates:

🔹165 mg × 5/200 =4.1 mL

Answer 5

Correct Answers:

Yes, because the total daily dose is 900 mg, which is within the safe range of 700 mg to 1400 mg.

Rationale :

🔹 Weight conversion: 77 lb → 35 kg, essential for mg/kg/day dosing.

🔹 Safe range:

20 mg × 35 kg = 700 mg/day

40 mg × 35 kg = 1400 mg/day

→ Safe range = 700–1400 mg/day

🔹 Ordered dose: 300 mg × 3 doses/day = 900 mg/day.

🔹 900 mg/day fits safely within the recommended mg/kg range.

🔹 This confirms that both the dose and frequency are appropriate and safe for the child.

600 mg/day

🔹 Incorrect—true daily dose is 900 mg, not 600 mg.

🔹 Also suggests a dose below the safe range.

Below safe range

🔹 Incorrect—900 mg/day is not below 700 mg; it is within range.

1200 mg exceeds safe range

🔹 Incorrect: ordered dose is 900 mg, not 1200 mg.

🔹 1200 mg would still actually be within the safe range.

Answer 6

Correct Answers:

1 tsp

Rationale :

🔹 1 teaspoon (tsp) equals 5 mL, which is a standard and commonly taught household conversion.

🔹 Since the prescription is for 5 mL, this directly corresponds to 1 tsp with no extra math needed.

🔹 Using teaspoons helps clients and caregivers measure accurately at home with household tools.

🔹 Teaching the correct tsp equivalent reduces the risk of underdose or overdose.

🔹 This conversion is especially important in pediatric and home dosing, where mL-to-tsp understanding is critical.

5 tsp

🔹 5 tsp = 25 mL, which is five times the ordered volume.

🔹 This would result in dangerous overdosing of the medication.

0.5 tsp

🔹 0.5 tsp = 2.5 mL, giving half the prescribed dose.

🔹 Leads to subtherapeutic dosing and possible treatment failure.

2.5 tsp

🔹 2.5 tsp = 12.5 mL, more than double the prescribed volume.

🔹 Increases risk of toxicity and adverse effects.

Answer 7

Correct Answers:

Double-check the medication dosage with another nurse before administration.?

Rationale :

🔷 High-alert medications (e.g., insulin, heparin, opioids, chemo) have a higher risk of causing serious harm if given incorrectly.

🔷 Independent double-checks with another nurse reduce errors in dose, route, patient, and drug.

🔷 This is a recommended safety standard in most institutions and aligns with patient safety goals.

🔷 A second nurse verifying the dose helps catch calculation mistakes or look-alike/sound-alike errors.

🔷 This practice supports a culture of safety and shared responsibility in medication administration.

Administer the medication quickly

🔷 Speed does not equal safety; rushing increases error risk.

🔷 High-alert medications require extra caution and verification, not haste.

Have the client verify the dose

🔷 Clients generally lack the pharmacologic knowledge to confirm dose accuracy.

🔷 Responsibility for verification lies with licensed professionals, not patients.

Assume pharmacy dose is correct

🔷 Even pharmacy-prepared doses can be incorrect; nurses are the final safety check.

🔷 Never assume—always verify high-alert meds.

Answer 8

Correct Answers:

1.5

Rationale :

🔸 The nurse divides the ordered dose (450 mg) by the available strength (300 mg) to determine number of capsules.

🔸 450÷300=1.5 capsules450 ÷ 300 = 1.5 { capsules}450÷300=1.5 capsules

Answer 9

Correct Answers:

15 ml

Rationale :

🔵 The nurse must know that 1 oz = 30 mL as a standard conversion.

🔵 0.5 oz × 30 mL/oz = 15 mL, so the ordered amount of apple juice is 15 mL.

🔵 Accurate volume measurement ensures the client receives the correct diluent or vehicle volume with the medication.

🔵 Rounding to the nearest whole number is appropriate here and matches the exact value (15).

🔵 Understanding apothecary-to-metric conversions is essential for safe medication preparation.

5 mL

🔵 5 mL is only one-third of 15 mL.

🔵 This would provide less than the ordered volume, altering dilution.

7.5 mL

🔵 7.5 mL is half of 15 mL; still incorrect.

🔵 Indicates confusion between oz and tablespoon conversions.

10 mL

🔵 10 mL is not equivalent to 0.5 oz.

🔵 Miscalculation of 30 mL per ounce.

Answer 10

Correct Answers:

16 fluid ounces

Rationale :

🟣 In the apothecary/household system, 1 pint = 16 fluid ounces (fl oz).

🟣 This is a fixed conversion used frequently in liquid medication volumes and IV solutions.

🟣 Knowing pint-to-oz conversion helps nurses understand total volumes (e.g., daily intake,outputs, IV fluids).

🟣 This also supports safe parent teaching when using household measures at home.

🟣 It is a foundational memory point for exam calculations and clinical practice.

20 fluid ounces

🟣 Overestimates a pint; 20 fl oz ≠ 1 pint.

🟣 Could cause volume miscalculations.

12 fluid ounces

🟣 Underestimates true volume of a pint.

🟣 Could underdose liquid medications or miscalculate fluid intake.

8 fluid ounces

🟣 8 fl oz = 1 cup, not 1 pint.

🟣 A pint is two cups, so 16 fl oz.
