Question

A nurse is reinforcing teaching with a client who has a prescription for simvastatin. Which of the following instructions should the nurse provide?

Answer 1

Correct Answers:

Take the medication in the evening hours.

Rationale :

🔷 Simvastatin is a statin medication that reduces cholesterol by inhibiting HMG-CoA reductase, an enzyme most active at night.

🔷 Taking the medication in the evening maximizes its therapeutic effect because the liver synthesizes most cholesterol during nighttime hours.

🔷 Evening dosing enhances LDL-lowering effects and improves overall lipid control.

🔷 This teaching is essential to ensure optimal medication effectiveness and long-term cardiovascular protection.

❌ Incorrect Options

❌ Grapefruit juice ↑ toxicity by inhibiting statin metabolism.

❌ Taking with meals is not necessary and does not improve absorption.

❌ Antacids do not enhance simvastatin action.

Answer 2

Correct Answers:

Bradycardia

Rationale :

🟩 Atenolol is a beta-1 selective blocker that slows the heart rate and reduces cardiac workload.

🟩 The most significant adverse effect is bradycardia, which can progress to heart block if unmonitored.

🟩 Nurses should check apical pulse before administration and withhold the dose if the pulse is too low.

🟩 Recognizing early signs of excessive cardiac suppression ensures client safety.

❌ Incorrect Options

❌ Neutropenia — not related to beta blockers.

❌ Anemia — atenolol does not affect hemoglobin.

❌ Hypokalemia — not caused by beta blockers.

Answer 3

Correct Answers:

Obtain an infusion pump to regulate the continuous flow of the medication.

Rationale :

🟧 Heparin must be infused with precise, controlled dosing to avoid excessive anticoagulation and bleeding.

🟧 An infusion pump ensures the medication is delivered at a safe, consistent rate.

🟧 Heparin has a narrow therapeutic range, so tight regulation prevents complications such as hemorrhage.

🟧 Pumps also enable rapid adjustment of infusion rates based on aPTT monitoring.

❌ Incorrect Options

❌ PT monitoring — PT is for warfarin, not heparin.

❌ Vitamin K — antidote for warfarin; protamine sulfate reverses heparin.

❌ Indwelling catheter — unnecessary and unrelated to IV heparin.

Answer 4

Correct Answers:

Discard regular insulin if it appears cloudy.

Rationale :

🟪 Regular insulin must always be clear, never cloudy. Cloudiness indicates contamination or breakdown.

🟪 Clear-to-cloudy technique prevents contamination of the rapid-acting insulin with NPH.

🟪 Ensuring both insulin vials are in proper condition prevents dosing errors and unsafe administration.

🟪 Teaching clients to inspect regular insulin ensures safe self-administration at home.

❌ Incorrect Options

❌ Inject air into NPH first, not regular.

❌ Draw up regular first, not NPH.

❌ Do NOT shake NPH — roll gently.

Answer 5

Correct Answers:

If they have had any past issues or allergies to the vaccine

Rationale :

🟦 The most important safety question before giving any vaccine is whether the client has a history of allergies or adverse reactions to vaccines or their components.

🟦 Certain vaccines contain egg protein, gelatin, latex, or neomycin, which may cause anaphylaxis in sensitive individuals.

🟦 Identifying contraindications prevents severe reactions and ensures safe immunization.

🟦 All other information is helpful but not safety-critical for vaccine administration.

❌ Incorrect Options

❌ Site preference — affects comfort only, not safety.

❌ Immunization card — for documentation, not screening.

❌ Questions about schedule — not related to allergic risk.

Answer 6

Correct Answers:

"I will notify my provider if my arms feel weak."

Rationale :

🔷 Atorvastatin can cause myopathy or rhabdomyolysis, conditions that present with muscle pain, tenderness, or weakness in the arms or legs.

🔷 These adverse effects can progress to serious complications, including renal failure from muscle breakdown.

🔷 Early reporting ensures the medication can be discontinued before irreversible muscle damage occurs.

🔷 Routine monitoring of creatine kinase levels helps detect muscle injury in clients taking statins.

❌ Incorrect Options

❌ No routine labs — incorrect; statins require liver function tests.

❌ Take without food — atorvastatin may be taken with or without food.

❌ Best in the morning — atorvastatin may be taken any time of day.

Answer 7

Correct Answers:

Improved range of motion

Rationale :

🟩 Prednisone is a glucocorticoid with strong anti-inflammatory effects, reducing joint swelling and stiffness in rheumatoid arthritis.

🟩 When inflammation decreases, clients experience improved mobility and joint function, indicating effective therapy.

🟩 Symptom relief occurs relatively quickly, often before structural changes in the joints occur.

🟩 Improved range of motion shows that inflammation is being controlled and the medication is achieving its intended effect.

❌ Incorrect Options

❌ Improved mood — prednisone may elevate mood but does not indicate arthritis improvement.

❌ Elevated blood glucose — an adverse effect, not a sign of therapeutic response.

❌ Increased blood pressure — side effect, not effectiveness.

Answer 8

Correct Answers:

Place one finger across the acromion process and measure 3 fingerbreadths below to the midpoint and center of the lateral aspect of the upper arm.

Rationale :

🟧 The deltoid muscle is the recommended site for adult IM hepatitis B vaccinations.

🟧 The correct method is to identify the acromion process, then measure about 2–3 fingerbreadths (or approximately 1–2 inches) below to locate the thickest part of the deltoid.

🟧 This ensures accurate medication delivery into muscle tissue while avoiding nerves and blood vessels.

🟧 Proper landmarking prevents injection complications such as nerve injury or poor vaccine absorption.

❌ Incorrect Options

❌ Mid-arm between elbow/shoulder — incorrect; too low.

❌ Thigh locations — these are vastus lateralis, not deltoid.

❌ Middle thigh landmarks — not used for hepatitis B in adults.

Answer 9

Correct Answers:

42 units

Rationale :

🟪 The prescription includes 14 units of regular insulin and 28 units of NPH insulin, both to be drawn into the same syringe.

🟪 The total amount prepared is simply the sum of both ordered doses.

🟪 Accuracy in combining insulins supports safe glycemic control throughout the day.

🟪 The nurse must still follow mixing guidelines, but the total prepared dose is 42 units.

❌ Incorrect Options

❌ 28 — NPH only.

❌ 14 — regular only.

❌ 32 — incorrect math.

Answer 10

Correct Answers:

"Heparin will be continued until the warfarin reaches a therapeutic level."

Rationale :

🟦 Warfarin takes 3–5 days to reach a therapeutic INR because it works by reducing vitamin K–dependent clotting factors.

🟦 Heparin provides immediate anticoagulation, so it is continued until warfarin becomes effective.

🟦 Overlapping therapy prevents clot progression or embolization during the transition period.

🟦 Once the INR is within therapeutic range (typically 2–3), heparin can be safely discontinued.

❌ Incorrect Options

❌ Ask provider — unnecessary; nurse should explain.

❌ “Work together to dissolve clots” — anticoagulants prevent clots; do not dissolve them.

❌ “Heparin enhances warfarin” — incorrect pharmacology.
