Questions & Verified Answers
1. An elderly patient is prescribed a Selective Serotonin Reuptake Inhibitor (SSRI). Which
electrolyte abnormality should the provider monitor for closely?
A. Hyperkalemia
B. Hypocalcemia
C. Hypermagnesemia
D. Hyponatremia
Answer: D
Rationale: SSRIs can cause Syndrome of Inappropriate Antidiuretic Hormone (SIADH), which leads to
hyponatremia, particularly in the elderly population. This is important because the nurse must choose
the action that keeps the client safest while still meeting their basic needs. Always think about safety
first when answering these questions. This knowledge supports safe care and helps the nurse teach
the client and family clearly and simply. Clear teaching improves cooperation and reduces anxiety.
2. When prescribing Metformin for a patient with Type 2 Diabetes, which laboratory value is
the most critical contraindication if significantly abnormal?
A. Estimated Glomerular Filtration Rate (eGFR) below 30 mL/min
B. Low Hemoglobin A1c
C. Elevated Liver Enzymes (ALT/AST)
D. High Serum Potassium
Answer: A
Rationale: Metformin is cleared renally and carries a risk of lactic acidosis. An eGFR below 30 mL/min
is a strict contraindication for its use. In practice, this guides the nurse to set priorities and protect the
client from harm. Safety, nutrition, and clear communication are frequent priorities. This knowledge
supports safe care and helps the nurse teach the client and family clearly and simply. Clear teaching
improves cooperation and reduces anxiety.

3. Which side effect of Second-Generation Antipsychotics (SGAs) requires regular
monitoring of waist circumference and fasting glucose?
A. Extrapyramidal Symptoms (EPS)
B. Agranulocytosis
C. Metabolic Syndrome
D. Prolonged QT Interval
Answer: C
Rationale: SGAs like olanzapine and clozapine are associated with significant weight gain,
dyslipidemia, and insulin resistance, collectively known as metabolic syndrome. This is important
because the nurse must choose the action that keeps the client safest while still meeting their basic
needs. Always think about safety first when answering these questions. Remembering this point will
help you decide the best nursing action when similar questions appear on the exam. Link the answer
to the client’s current condition and risk level.
4. A patient taking Warfarin for atrial fibrillation is prescribed a broad-spectrum antibiotic.
How should the provider expect the INR to change?
A. The INR will decrease due to increased Vitamin K synthesis.
B. The INR will decrease because antibiotics induce CYP450 enzymes.
C. The INR will remain stable as antibiotics do not interact with Warfarin.
D. The INR will increase due to the depletion of Vitamin K-producing gut bacteria.
Answer: D
Rationale: Broad-spectrum antibiotics kill intestinal flora that produce Vitamin K, enhancing the
anticoagulant effect of Warfarin and raising the INR. Remembering this point will help you decide the
best nursing action when similar questions appear on the exam. Link the answer to the client’s current
condition and risk level. Knowing the reason behind the correct answer makes it easier to rule out the
wrong options quickly. Look for the choice that protects the client and matches the priority need.
