NUR 210 | NUR210 Exam 3 V3 – Updated and Latest Questions and
Correct Answers with Rationale – Galen College of Nursing
1. A patient with Type 1 Diabetes is prescribed Insulin Aspart (Novolog) before breakfast.
When should the nurse ensure the patient’s meal tray is at the bedside?
A. 30 to 45 minutes after administration
B. Within 5 to 15 minutes of administration
C. Exactly 60 minutes after administration
D. Prior to checking the blood glucose level
Answer: B
Rationale: Insulin Aspart is a rapid-acting insulin with an onset of 10-20 minutes. To
prevent hypoglycemia, the nurse must ensure the meal is readily available within 5-15
minutes of the injection.
2. A client is scheduled for a CT scan with intravenous contrast. Which medication must the
nurse withhold for 48 hours following the procedure?
A. Metformin
B. Glyburide
C. Pioglitazone
D. Sitagliptin
Answer: A
Rationale: Metformin should be withheld before and for 48 hours after contrast studies to
prevent the risk of lactic acidosis if contrast-induced renal failure occurs.
3. A patient receiving Levothyroxine for hypothyroidism reports feeling ‘fluttering’ in the
chest and difficulty sleeping. What is the nurse’s priority action?
A. Reassure the patient these are common side effects
B. Suggest the patient take the dose at bedtime
C. Instruct the patient to double the next dose
D. Assess the heart rate and notify the provider
Answer: D
, Rationale: Palpitations and insomnia are signs of hyperthyroidism or toxicity. The nurse
must assess for tachycardia and arrhythmias and report these to the prescriber for a
dosage adjustment.
4. Which lab value would cause the nurse to hold a scheduled dose of Spironolactone?
A. Sodium 138 mEq/L
B. Magnesium 1.9 mg/dL
C. Glucose 110 mg/dL
D. Potassium 5.4 mEq/L
Answer: D
Rationale: Spironolactone is a potassium-sparing diuretic. A potassium level of 5.4 mEq/L
indicates hyperkalemia, necessitating withholding the drug to prevent cardiac
complications.
5. A patient is prescribed Albuterol and Beclomethasone inhalers. What is the correct
teaching regarding administration?
A. Use the Albuterol first, wait 5 minutes, then use the Beclomethasone
B. Use the Beclomethasone first to reduce inflammation
C. Mix the two medications in a nebulizer for faster action
D. Wait 30 minutes between using the two different inhalers
Answer: A
Rationale: The bronchodilator (Albuterol) should be used first to open the airways,
allowing better penetration of the corticosteroid (Beclomethasone) into the lungs.
6. A patient taking Prednisone for an acute asthma exacerbation asks why the dose is being
gradually reduced. The nurse explains this prevents:
A. Hyperglycemic crisis
B. Fluid volume overload
C. Adrenal insufficiency
D. Gastrointestinal bleeding
Answer: C
Rationale: Exogenous corticosteroids suppress the adrenal glands. Tapering the dose
allows the adrenal glands to resume natural cortisol production, preventing adrenal crisis.
