Introduction
The NUR 210 Exam 3 assessment evaluates the nursing student's
mastery of pharmacologic principles applied to major body
systems. It focuses on drug classifications, mechanisms of action,
therapeutic uses, and critical nursing considerations for high-alert
medications. The exam tests clinical judgment through multiple-
choice questions that mirror real-world patient scenarios,
emphasizing safe administration, monitoring parameters, and
patient education. Success requires integrating foundational
pharmacokinetic and pharmacodynamic concepts with practical
application to ensure safe and effective medication management
across diverse patient populations.
Question 1
A patient with hypertension is prescribed hydrochlorothiazide.
Which electrolyte imbalance should the nurse monitor for as the
most common adverse effect?
,A. Hyperkalemia
B. Hypernatremia
C. Hypokalemia
D. Hypercalcemia
🟢 C. Hypokalemia
🔴 RATIONALE: Thiazide diuretics such as hydrochlorothiazide are
associated with hypokalemia, hyponatremia, and hypovolemia as
common adverse reactions due to their action in the distal
convoluted tubule. Hyperkalemia is more associated with
potassium-sparing diuretics like spironolactone .
Question 2
A nurse is preparing to administer furosemide to a patient with
heart failure. Which assessment finding requires immediate
intervention before giving the medication?
A. Blood pressure 98/60 mmHg and potassium 2.9 mEq/L
B. Blood pressure 128/78 mmHg and potassium 4.2 mEq/L
C. Heart rate 72 beats per minute and sodium 138 mEq/L
D. Respiratory rate 18 breaths per minute and calcium 9.2 mg/dL
🟢 A. Blood pressure 98/60 mmHg and potassium 2.9 mEq/L
🔴 RATIONALE: Loop diuretics like furosemide cause significant
potassium loss and can lead to hypotension. A potassium level of
2.9 mEq/L is critically low (normal range 3.5–5.0 mEq/L) and
increases the risk of dysrhythmias. The blood pressure is
borderline; administering furosemide could worsen hypotension.
These findings warrant provider notification before administration
.
, Question 3
A patient with severe head trauma has an order for mannitol.
What is the primary therapeutic effect the nurse should expect?
A. Reduction of intracranial pressure through osmotic diuresis
B. Increased renal perfusion through vasodilation
C. Decreased cerebral blood flow through vasoconstriction
D. Enhanced sodium excretion through aldosterone inhibition
🟢 A. Reduction of intracranial pressure through osmotic diuresis
🔴 RATIONALE: Mannitol is an osmotic diuretic that creates
osmotic pressure at the glomerulus, pulling fluid into renal
tubules and promoting significant fluid removal. Its primary
clinical indication is increased intracranial pressure and cerebral
edema .
Question 4
A patient is prescribed spironolactone for heart failure. Which
laboratory value requires the nurse to hold the medication and
notify the provider?
A. Potassium 5.8 mEq/L
B. Sodium 134 mEq/L
C. Creatinine 1.0 mg/dL
D. Blood urea nitrogen 18 mg/dL
🟢 A. Potassium 5.8 mEq/L
