Question 1 of 5
During a blood transfusion, the patient begins to have chills and back pain. What is the nurse™s priority action?
Correct Answer: D
Rationale: The patient is exhibiting signs of a transfusion reaction, specifically indicating the possibility of a febrile non-hemolytic transfusion reaction. Chills and back pain are common symptoms of this type of reaction. The nurse's priority action in this situation is to discontinue the blood transfusion immediately to prevent further complications and potential harm to the patient. It is crucial to notify the prescriber promptly so that appropriate interventions can be initiated. Observing for other symptoms and slowing the infusion rate are important actions but may not be the priority in this scenario where the patient is experiencing signs of a possible transfusion reaction. It is not appropriate to tell the patient that these symptoms are a normal reaction, as they indicate a potential complication that needs immediate attention.
Question 2 of 5
When reading about a drug, the nurse learns it has a median toxic dose of 50 mg. The patient has been receiving 60 mg of the drug. What analysis does the nurse make?
Correct Answer: C
Rationale: Median toxic dose (TD50) is where 50% show toxicity-60 mg exceeds this, raising adverse effect risk (e.g., toxicity signs), not lethality for all. Effect may persist, not fail. Efficacy/potency are defined, just exceeded. Lethal dose (LD50) differs-60 mg isn't half lethal. Excess drives risk, per pharmacodynamics.
Question 3 of 5
The patient with schizophrenia is sitting quietly in a chair. The patient does not respond much to what is happening and has a lack of interest in the environment. How does the nurse interpret this assessment?
Correct Answer: D
Rationale: Schizophrenia involves positive symptoms (e.g., hallucinations) and negative symptoms (e.g., apathy, withdrawal). The patient's quiet demeanor, lack of responsiveness, and disinterest align with negative symptoms, which diminish normal behaviors like motivation or social engagement. Depression might present similarly but isn't assumed without further evidence like sadness or hopelessness. Hearing voices suggests positive symptoms, but the scenario lacks indicators like distractedness. Positive symptoms involve added behaviors (e.g., delusions), not subtraction, as seen here. The nurse interprets this based on schizophrenia's symptomology, recognizing negative symptoms as a core feature, making choice D the most accurate clinical interpretation.
Question 4 of 5
During pharmacology class, the student nurse asks the nursing instructor how students will ever learn about the individual antibiotic drugs since there are so many. What is the best response by the nursing instructor?
Correct Answer: D
Rationale: Learning a representative (prototype) drug from each antibiotic class simplifies understanding by focusing on shared traits-mechanisms, effects, and side effects-reducing the burden of memorizing every drug. Mnemonics aid recall but don't teach concepts. Flow charts organize but lack depth. Categorizing is broad, while prototypes offer a practical, foundational approach, widely used in pharmacology education for mastery.
Question 5 of 5
A 56-year-old man with progressive, chronic renal impairment is awaiting renal replacement therapy. His treatment includes calcium carbonate tablets, furosemide, irbesartan and amlodipine. He is admitted severely unwell with a BP of 40 by palpation, pulse 112. An ECG shows a broad complex tachycardia with no P waves. Serum Ca2+ is 2.3 mmol/L, PO4 1.7 mmol/L, creatinine 785 μmol/L, Na+ 142 mmol/L, K+ 7.4 mmol/L. Which of the following would be appropriate management?
Correct Answer: C
Rationale: Severe hyperkalemia (K+ 7.4 mmol/L) in renal failure causes broad complex tachycardia, risking arrest. Amiodarone treats arrhythmias but not hyperkalemia's cause. Digoxin is contraindicated in hyperkalemia and renal failure. IV calcium gluconate stabilizes cardiac membranes, countering potassium's depolarizing effect, appropriate immediate management. Pacing or colestyramine (potassium binder) are secondary. Calcium's rapid action protects the heart, buying time for dialysis, critical in this life-threatening scenario.
