,Q1. A patient with chronic heart failure is prescribed digoxin. Which laboratory
value, in conjunction with clinical signs, would most accurately indicate digoxin
toxicity?
A. Serum potassium of 3.0 mEq/L
B. Serum digoxin level of 1.2 ng/mL
C. Magnesium level of 1.8 mEq/L
D. Serum creatinine of 1.0 mg/dL
Correct Answer: A. Serum potassium of 3.0 mEq/L
Rationale: Hypokalemia (K+ <3.5) potentiates digoxin toxicity by increasing myocardial
sensitivity to the drug, even at 'therapeutic' serum levels. A digoxin level of 1.2 ng/mL is
within normal range (0.5-2.0), but with hypokalemia, toxicity can occur. Magnesium and
creatinine levels are not primary indicators of digoxin toxicity.
Why Wrong:
B - This is a therapeutic level, not toxic, even though toxicity can occur with
hypokalemia, the lab value itself is not indicative.
C - Magnesium level is within normal limits and is not the primary electrolyte
imbalance associated with digoxin toxicity.
D - Creatinine is normal and does not directly indicate digoxin toxicity; it may affect
clearance but not the immediate toxic effect.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 33.
Q2. Which pathophysiological mechanism best explains the development of metabolic
alkalosis in a patient with prolonged vomiting?
A. Loss of hydrogen ions and chloride leading to increased bicarbonate reabsorption
B. Compensatory hyperventilation causing increased carbon dioxide exhalation
C. Renal retention of potassium due to aldosterone release
D. Increased anaerobic metabolism producing lactic acid
Correct Answer: A. Loss of hydrogen ions and chloride leading to increased
bicarbonate reabsorption
Rationale: Prolonged vomiting leads to loss of gastric HCl, causing metabolic alkalosis.
The loss of hydrogen ions (H+) and chloride (Cl-) triggers the kidneys to reabsorb
bicarbonate (HCO3-) to maintain electroneutrality, resulting in elevated plasma HCO3-.
Hyperventilation would cause respiratory alkalosis, not metabolic. Potassium retention
and lactic acidosis are not primary mechanisms.
Why Wrong:
B - Hyperventilation causes respiratory alkalosis, not metabolic alkalosis, and is a
compensatory response to metabolic acidosis, not alkalosis.
C - Aldosterone release occurs in volume depletion but leads to potassium excretion,
not retention, and does not directly cause metabolic alkalosis.

, D - Anaerobic metabolism produces lactic acid, causing metabolic acidosis, not
alkalosis.

for Disease in Adults and Children, 9th Ed., Ch. 4.
Q3. A nurse is preparing to administer a blood transfusion. Which action is most
critical to prevent a transfusion-associated circulatory overload (TACO)?
A. Administering the transfusion over 4 hours
B. Premedicating with acetaminophen and diphenhydramine
C. Assessing the patient's fluid volume status and cardiac reserve
D. Verifying blood type and crossmatch with another nurse
Correct Answer: C. Assessing the patient's fluid volume status and cardiac reserve
Rationale: TACO is caused by rapid infusion of blood products overwhelming the
circulatory system, especially in patients with compromised cardiac or renal function.
Assessing fluid volume status and cardiac reserve helps identify at-risk patients and guides
rate and volume of transfusion. Prolonging infusion time does not prevent TACO if the
volume is excessive. Premedication prevents allergic reactions, not TACO. Blood type
verification prevents hemolytic reactions, not TACO.
Why Wrong:
A - Slower infusion reduces risk but does not address the underlying volume overload;
the key is assessing the patient's ability to handle the volume.
B - Premedication with acetaminophen and diphenhydramine is for febrile or allergic
reactions, not TACO.
D - Verification of blood type prevents hemolytic transfusion reactions, not circulatory
overload.
Reference: Gulanick, M. & Myers, J.L. (2026). Nursing Care Plans: Diagnoses,
Interventions, and Outcomes, 10th Ed., Ch. 8.
Q4. Which ethical principle primarily guides a nurse's decision to respect a
competent patient's refusal of life-sustaining treatment?
A. Beneficence
B. Autonomy
C. Justice
D. Nonmaleficence
Correct Answer: B. Autonomy
Rationale: Autonomy respects the patient's right to self-determination and to make
decisions about their own healthcare, even if those decisions contradict medical advice.
Beneficence requires acting in the patient's best interest, but it does not override a
competent patient's choice. Justice relates to fairness in resource allocation, and
