  • D. Insulin lispro

Explanation: Insulin glargine is a long-acting insulin formulated to provide a steady release and must not be mixed with other insulins.

Correct answer: Insulin glargine
Hard
  • A. Assess respiratory effort and airway protection
  • B. Measure the patient’s urine output
  • C. Inspect the patient’s feet for injury
  • D. Ask about the usual meal pattern

Explanation: Increasing drowsiness can reduce airway protection, while deep rapid breathing indicates severe metabolic acidosis.

  • A. Take an extra dose before the study
  • B. Discuss temporarily withholding it with the prescriber
  • C. Replace it with rapid-acting insulin permanently
  • D. Stop taking all diabetic medicines for one week

  • A. Give sweet juice slowly by mouth
  • B. Place glucose gel between the teeth
  • C. Administer prescribed glucagon and call for help
  • D. Give the person the next scheduled insulin dose

Correct answer: Administer prescribed glucagon and call for help
  • A. Persistent microalbuminuria
  • B. Occasional post-meal thirst
  • C. A single normal urine test
  • D. Mild sweating before breakfast

Explanation: Persistent urinary albumin loss can be an early sign of diabetic kidney damage, often appearing before a major fall in renal function.

Correct answer: Persistent microalbuminuria
Fairly easy
  • A. The medicine prevents all insulin reactions
  • B. The medicine may mask warning signs of hypoglycaemia
  • C. The medicine should be stopped after one normal reading
  • D. The medicine always causes severe hyperglycaemia

Explanation: Beta blockers such as propranolol can blunt adrenergic warning signs of hypoglycaemia, especially tachycardia and tremor.

Correct answer: The medicine may mask warning signs of hypoglycaemia
Hard
  • A. Encourage the patient to walk in the corridor
  • B. Check for hypocalcaemia and notify the prescriber
  • C. Offer a high-fibre snack with extra fluids
  • D. Place the patient in a warm shower

Explanation: Perioral tingling and carpopedal spasm suggest hypocalcaemia caused by impaired parathyroid function after thyroid surgery.

Correct answer: Check for hypocalcaemia and notify the prescriber
  • A. High sodium and low potassium
  • B. Low sodium and high potassium
  • C. High calcium and low glucose only
  • D. Low sodium and low potassium

Explanation: Primary adrenal insufficiency causes deficient aldosterone, leading to sodium loss and potassium retention.

Correct answer: Low sodium and high potassium
Very hard
  • A. Institute seizure precautions and notify the prescriber
  • B. Encourage the patient to drink several litres of water
  • C. Offer a low-sodium diet with unrestricted fluids
  • D. Ambulate the patient independently every hour

Explanation: Severe hyponatraemia can cause cerebral oedema, confusion and seizures, so safety and seizure precautions are the immediate priority.

Correct answer: Institute seizure precautions and notify the prescriber
  • A. Shake the vial vigorously before drawing the dose
  • B. Roll the vial gently between the palms before drawing the dose
  • C. Warm the vial in hot water for several minutes
  • D. Draw the dose immediately after removing the vial from the refrigerator

Explanation: NPH insulin is a suspension, so it should be gently rolled to mix the insulin evenly without creating bubbles.

Correct answer: Roll the vial gently between the palms before drawing the dose
Hard
  • A. Take the tablet now and skip breakfast
  • B. Take the tablet with a glass of milk only
  • C. Wait to take the tablet until ready to eat
  • D. Double the next dose after eating breakfast

Explanation: Glipizide stimulates insulin release and can cause hypoglycaemia when taken without an adequate meal.

Correct answer: Wait to take the tablet until ready to eat
  • A. High glucose, high bicarbonate and low ketones
  • B. High glucose, low bicarbonate and positive ketones
  • C. Normal glucose, high bicarbonate and positive ketones
  • D. Low glucose, low bicarbonate and negative ketones

Explanation: Diabetic ketoacidosis causes insulin deficiency, increased ketone production and metabolic acidosis.

Correct answer: High glucose, low bicarbonate and positive ketones
Fairly easy
  • A. Continue wearing the shoe until the blister dries
  • B. Apply a heating pad to improve circulation
  • C. Protect the area and avoid pressure on the heel
  • D. Open the blister with a sterile needle at home

Explanation: A diabetic foot blister should be protected from further pressure and assessed for infection or tissue damage.

Correct answer: Protect the area and avoid pressure on the heel
Moderate
  • A. Rub the eyes firmly to remove the gritty feeling
  • B. Use prescribed lubricating drops and protect the eyes
  • C. Restrict fluids to reduce swelling around the eyes
