A. At the start of medication therapy: Side effects are most common when a client first begins taking a new medication because the body is not yet accustomed to the drug. Over time, tolerance may develop, and some side effects may diminish.

B. When clients take medication on an empty stomach – Some medications cause more side effects when taken on an empty stomach (e.g., NSAIDs causing gastritis), but this is not true for all medications.

C. When clients take high doses of medication – Higher doses may increase the risk of toxicity rather than routine side effects.

D. When clients take multiple medications – Drug interactions are more likely when taking multiple medications, but this does not mean that side effects are most common in this situation.

A. Instruct the client to wait until you are completely finished before asking any questions – This discourages client engagement and may prevent the nurse from addressing concerns in real time.

B. Teach information at a 5th-grade level – While simple language is beneficial, the level should be tailored to the client’s comprehension rather than assuming all clients understand at a 5th-grade level.

C. Talk about the least important information in the beginning and the most important at the end – Clients may have limited attention spans, and it is better to start with essential information.

D. Use teach-back method and active learning: The teach-back method ensures that the client understands the medication instructions by asking them to repeat the information. Active learning engages the client in the learning process, improving retention.

• 10 mL medication
• 3 oz formula (1 oz = 30 mL → 3 × 30 = 90 mL)
• 2 oz juice (2 × 30 = 60 mL)
• IV fluids at 20 mL/hr for 8 hours (20 × 8 = 160 mL)

Total intake: 10 + 90 + 60 + 160 = 320 mL

Correct Answer: 320

A. A 5 mL slip-tip syringe: A 5 mL syringe is the best option for measuring 6.25 mL, although it may require drawing up the medication in two separate amounts (e.g., 5 mL + 1.25 mL). A larger syringe (e.g., 10 mL) would be less precise.
B. An insulin syringe – Insulin syringes measure units of insulin, not milliliters, and are not appropriate for non-insulin medications.
C. A 1 mL TB syringe – This is used for very small doses (up to 1 mL) and is not practical for 6.25 mL.
D. A 3 mL syringe – This is too small for 6.25 mL.

B. Liver: Grapefruit juice inhibits CYP3A4 enzymes in the liver, which metabolize many drugs (e.g., statins, calcium channel blockers). This inhibition can lead to increased drug levels and toxicity.

A. Gall bladder – The gall bladder stores bile but does not metabolize drugs.

C. Kidney – The kidneys excrete drugs, but grapefruit juice does not significantly impact renal metabolism.

D. Small bowel – Some drug metabolism occurs in the intestines, but grapefruit juice primarily affects liver enzymes.

A. Below 1.0: Too low, indicating inadequate anticoagulation, increasing the risk of clot formation.

B. 1.0-2.0: Subtherapeutic, meaning the medication is not effectively preventing clot formation.

C. Above 3.0: Too high, increasing the risk of bleeding complications

D. 2.0-3.0: The normal INR (International Normalized Ratio) for a client not on anticoagulants is 0.8-1.2. For clients on warfarin or other blood thinners, the target therapeutic range is typically 2.0-3.0, which reduces the risk of blood clots while minimizing the risk of bleeding. Some conditions, such as mechanical heart valves, may require a higher target range (2.5-3.5).

A. "The list obtained from the client does not need to list medications that are not prescribed by the client's provider." All medications must be documented, including over-the-counter drugs, herbal supplements, and non-prescribed medications to avoid drug interactions.

B. "A nurse should write a verbal order in the medical record for medications the client was taking at home." Verbal orders should be avoided unless in an emergency, and reconciliation should be based on a review of documented prescriptions and client reports rather than nurse-written orders.

C. "Complete the reconciliation process one time only when the client is first admitted to the hospital." Medication reconciliation must be repeated at every transition of care, including admission, transfer between units, and discharge.

D. "A comprehensive list of medications is reviewed upon admission/transfer and provided for the client at the time of discharge." Medication reconciliation is a critical process to ensure continuity of care and prevent medication errors. It must be conducted at every transition of care (admission, transfer, and discharge) to compare the client’s home medications with hospital prescriptions and make adjustments as needed.

A. 1630 and 1930: Peak and trough levels are used to monitor drug effectiveness and prevent toxicity. Trough levels (lowest drug concentration) are drawn right before the next dose-1745 would be slightly too late. Peak levels (highest drug concentration) are drawn 30-60 minutes after administration (for IV drugs). Since the next dose is at 1800, the trough should be drawn just before the dose (1630) and the peak should be drawn 30-60 minutes after the dose (1930).

B. 1100 and 1700- Incorrect timing, not close to dose administration.

C. 1400 and 2200- Too far from the scheduled 1800 dose.

D. 1745 and 1830- Trough is too close to administration, peak is too early.

Formula: 1 kg = 2.2 lbs

• 198 ÷ 2.2 = 90 kg (rounded to nearest whole number).

Correct answer: 90

Formula: 1 kg = 1000 g, 1 kg = 2.2 lbs

• 3600 g = 3.6 kg
• 3.6 × 2.2 = 7.92 lbs
• Rounded to the nearest tenth = 7.9
