Answer 3

Correct Answers:

2.1

Rationale :

Tobramycin 3 mg/kg/day IM in 3 divided doses

Weight = 85 kg

Supply = 40 mg/mL

🔹 Step 1: Daily dose = 3 mg × 85 kg = 255 mg/day

🔹 Step 2: Divide into 3 doses → 255 ÷ 3 = 85 mg per dose

🔹 Step 3: Formula → mL = mg ordered ÷ mg/mL

🔹 Step 4: 85 ÷ 40 = 2.125 mL

🔹 Step 5: Round to nearest tenth → 2.1 mL

Answer 5

Correct Answers:

Fentanyl 25 mcg/hr transdermal patch

Rationale :

🟦 Fentanyl patches are only appropriate for chronic, severe pain and require the client to be opioid-tolerant to prevent respiratory depression.

🟦 This form delivers continuous, potent opioid absorption, which is dangerous in opioid-naïve clients.

🟦 Using this patch without verifying pain history or opioid tolerance risks sedation, hypoventilation, and overdose.

🟦 Fentanyl transdermal systems carry a black box warning, requiring strict safety evaluation before use.

🟦 Because of its potency and risk profile, this order must be verified with the provider before administration.

❌ Incorrect Options

🟩 Regular insulin 8 units before meals

🟩 This is a standard dose and routine timing for short-acting insulin to manage post-meal glucose.

🟩 Order is complete and appropriate.

🟩 Meloxicam 15 mg PO daily

🟩 This is a common NSAID dose used for arthritis and chronic pain.

🟩 No safety concerns requiring clarification unless patient-specific factors apply.

🟩 Docusate sodium 200 mg at bedtime

🟩 This is a typical dose of a stool softener, used safely for constipation prevention.

🟩 Order is clear and appropriate.
