Pharmacological and Parenteral Therapies is one of the largest sections of the NCLEX-RN test plan. These free practice questions cover medication administration, adverse effects, and high-alert drugs — each with a full rationale.
A client is prescribed insulin glargine (Lantus). Which statement by the client indicates a need for further teaching?
RATIONALE
Insulin glargine (Lantus) is a long-acting insulin that must NEVER be mixed with other insulins. Mixing alters its pharmacokinetics and can cause unpredictable blood glucose control.
A client on warfarin (Coumadin) has an INR of 5.2. Which action should the nurse anticipate?
RATIONALE
A therapeutic INR for most clients on warfarin is 2–3. An INR of 5.2 indicates a high bleeding risk. Vitamin K is the antidote for warfarin. (Protamine sulfate reverses heparin, not warfarin.)
A client receiving furosemide (Lasix) should be monitored most closely for which electrolyte imbalance?
RATIONALE
Furosemide is a loop diuretic that causes significant potassium loss. Hypokalemia can lead to cardiac dysrhythmias and increases the risk of digoxin toxicity. Monitor potassium and encourage potassium-rich foods.
Which findings indicate digoxin toxicity? Select all that apply.
RATIONALE
Early digoxin toxicity presents with nausea, vomiting, anorexia (not increased appetite), visual changes such as yellow-green halos, and bradycardia. Hypokalemia potentiates toxicity.
These are just a few samples. NCA's full platform runs a real Computer Adaptive Testing engine with detailed rationales for every question.
