Test yourself: 3 MACE practice questions

Tap an answer for instant feedback and the full rationale.

Question 1

Under general national medication administration standards, what is the acceptable time window for administering a time-critical scheduled medication ordered for 0800?

▸ Why D is the answer

The standard acceptable window for time-critical scheduled medications is 60 minutes total: 30 minutes before the scheduled time until 30 minutes after.

Question 2

Mr. Lang is taking a newly prescribed oral antihypertensive medication. Thirty minutes after receiving his morning dose, he rings his call bell and states he feels dizzy and lightheaded when trying to stand up. What is the Medication Aide's priority action?

▸ Why A is the answer

Dizziness upon standing is a sign of orthostatic hypotension, a common side effect of antihypertensives. The priority is resident safety (keeping him seated/lying down to prevent a fall) and immediately reporting the adverse effect to the nurse.

Question 3

When pouring a liquid medication from a multi-dose bottle into a graduated medicine cup, which technique ensures the Medication Aide measures the exact "Right Dose"?

▸ Why B is the answer

To ensure an accurate dose, the medicine cup must be held at eye level, and the measurement is read at the bottom of the meniscus (the lowest point of the curved surface of the liquid).

Question 1

A resident is ordered to receive albuterol (a bronchodilator) and fluticasone (a corticosteroid) via metered-dose inhalers at 0800. How should the Medication Aide administer these medications?

  • A) Administer the fluticasone first, wait 1 minute, then administer the albuterol.
  • B) Administer either medication first, but have the resident rinse their mouth immediately before the second inhaler.
  • C) Administer the albuterol first, wait 1 to 5 minutes, then administer the fluticasone.✓
  • D) Administer both medications consecutively without a waiting period to ensure maximum lung absorption.
Show rationale

Administering the albuterol first opens the airways (bronchodilation), allowing the fluticasone (corticosteroid) to penetrate deeper into the lungs. Waiting 1 to 5 minutes between different inhalers is the standard practice to allow the first drug to act.

Question 2

The MAR instructs the Medication Aide to administer digoxin 0.125 mg orally and to "hold for heart rate less than 60." The MA-C takes Mr. Harrison's radial pulse and counts 56 beats per minute. What is the MA-C's best action?

  • A) Give the medication and document the heart rate of 56 in the MAR.
  • B) Hold the medication, document a refusal, and notify the physician.
  • C) Wait 15 minutes, recheck the pulse, and administer the dose if it rises above 60.
  • D) Withhold the medication and immediately notify the delegating nurse.✓
Show rationale

When a vital sign falls outside the ordered parameters, the MA-C must withhold the dose and immediately report the finding to the delegating nurse for further assessment and instruction.

Question 3

When a resident is prescribed both an ophthalmic solution (eye drops) and an ophthalmic ointment for the same eye at the same time, which administration technique is correct?

  • A) Instill the drops first, wait 3 to 5 minutes, then apply the ointment.✓
  • B) Apply the ointment first, wait 1 minute, then instill the drops.
  • C) Instill the drops and apply the ointment immediately after to prevent eye irritation.
  • D) Mix the drops and ointment in the lower conjunctival sac simultaneously.
Show rationale

Drops must be instilled first because they absorb quickly. Waiting 3 to 5 minutes allows the drops to absorb fully before the ointment is applied, which creates a barrier.

Question 4

Mrs. Gable has an order for a nitroglycerin transdermal patch to be applied daily at 0900. When preparing to apply the new patch, the Medication Aide notices yesterday's patch is still on her right upper chest. What is the correct sequence of actions?

  • A) Apply the new patch to the left upper chest, then remove the old patch from the right side.
  • B) Remove the old patch, fold it in half with the sticky sides together, and apply the new patch to a different hairless area.✓
  • C) Remove the old patch, wipe the site clean, and apply the new patch to the exact same location.
  • D) Leave the old patch in place and apply the new patch next to it to maintain steady medication levels.
Show rationale

The correct procedure is to remove the old patch first, fold it sticky-side in for safe disposal, and rotate the application site by placing the new patch on a different clean, hairless area.

Question 5

A resident has difficulty swallowing and requests that all morning pills be crushed and mixed with applesauce. The MAR lists an acetaminophen tablet, a lisinopril tablet, and a pantoprazole delayed-release (DR) tablet. What is the Medication Aide's most appropriate action?

  • A) Crush all three tablets and mix them thoroughly into the applesauce.
  • B) Crush the pantoprazole DR and lisinopril, but administer the acetaminophen whole.
  • C) Crush the acetaminophen and lisinopril, but consult the nurse regarding the pantoprazole DR.✓
  • D) Refuse the resident's request and encourage them to swallow the pills whole with water.
Show rationale

Standard tablets like acetaminophen and lisinopril can generally be crushed. However, delayed-release (DR), enteric-coated (EC), or extended-release (ER) medications must never be crushed. The MA-C must hold the DR med and ask the nurse for an alternative order.
