Question 1 of 5
The following drugs must be avoided in severe renal failure (GFR ≤10 mL/min):
Correct Answer: D
Rationale: Metformin is contraindicated in severe renal failure due to the risk of lactic acidosis, a rare but potentially fatal side effect.
Question 2 of 5
What Medication is used as a Bronchodialtor?
Correct Answer: C
Rationale: Albuterol is a medication commonly used as a bronchodilator. It works by relaxing the muscles in the airways and increasing airflow to the lungs. This medication is commonly used to treat conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory issues where bronchodilation is needed to ease breathing difficulties. Warfarin is an anticoagulant used to prevent blood clots, Lovastatin is a statin medication used to lower cholesterol levels, and Valproate is an anticonvulsant used to treat seizures.
Question 3 of 5
A 60-year-old man with agitation is hospitalized on the medicine service for hyponatremia. He is being treated with intravenous fluids and haloperidol. He develops new onset of tremors and difficulty with ambulation and gait disturbance. What is the most likely explanation for these findings?
Correct Answer: A
Rationale: The patient's new tremors, ambulation issues, and gait disturbance during hospitalization for hyponatremia suggest a drug-related cause. Haloperidol, an antipsychotic, is known for extrapyramidal symptoms (EPS)-tremors, rigidity, and gait problems-making iatrogenic the correct answer. Infection lacks supporting fever or systemic signs. Neoplastic process is unlikely without prior hints. Viral encephalitis would involve fever, altered mentation beyond agitation, and CSF findings, none present. Haloperidol's dopamine D2 blockade in the nigrostriatal pathway induces EPS, especially in older patients, aligning with the timeline and symptoms. This iatrogenic effect is a common adverse reaction, distinguishing it from unrelated pathologies in this context.
Question 4 of 5
The nurse is providing medication education to a client with hypertension. The nurse teaches the client that the physician ordered a diuretic to decrease the amount of fluid in the client's body. Which statement best describes the nurse's instruction?
Correct Answer: A
Rationale: Explaining a diuretic's role in reducing fluid for hypertension is appropriate education, informing the client about its purpose in a clear, relevant way. Mechanism (e.g., sodium excretion) wasn't detailed-purpose was. Prototype drugs weren't specified, and consequences of non-use weren't covered. Appropriate education fits, enhancing adherence by linking the drug to the condition, a practical teaching goal.
Question 5 of 5
When reviewing the health history of a patient, the nurse will note that a potential contraindication to potassium supplements exists if the patient has which problem?
Correct Answer: C
Rationale: Patients with renal disease may have difficulty excreting potassium properly. If a patient with renal disease takes potassium supplements, it can lead to hyperkalemia, which is a high level of potassium in the blood. Hyperkalemia can be dangerous and may result in cardiac dysrhythmias and other serious complications. Therefore, patients with renal disease should avoid potassium supplements unless directed otherwise by their healthcare provider.
