1. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.

2. A client with peptic ulcer disease is being taught about lifestyle modifications by a nurse. Which client statement indicates a need for further teaching?

Correct answer: B

Rationale: The statement ‘I should take my antacids regularly, even if I don’t have symptoms’ indicates a misunderstanding. Antacids should only be taken when symptoms are present to neutralize excess stomach acid. Taking antacids regularly when not experiencing symptoms may lead to metabolic alkalosis. Choices A, C, and D are correct statements for a client with peptic ulcer disease as they all focus on avoiding irritants that can exacerbate the condition.

3. The nurse is assessing a client with left-sided heart failure. Which finding requires immediate intervention?

Correct answer: C

Rationale: Crackles in the lungs indicate pulmonary congestion in a client with left-sided heart failure and require immediate intervention to prevent respiratory failure. Crackles suggest fluid accumulation in the lungs, leading to impaired gas exchange and potentially respiratory distress. Shortness of breath, jugular venous distention, and peripheral edema are common manifestations of heart failure but do not directly indicate acute respiratory compromise like crackles in the lungs do.

4. A healthcare provider is assessing a client with a history of hypertension who is currently taking a diuretic. Which assessment finding is most important to report to the healthcare provider?

Correct answer: A

Rationale: A potassium level of 3.2 mEq/L is low and places the client at risk for cardiac arrhythmias, requiring immediate intervention. Hypokalemia can result from diuretic use and can lead to serious complications such as irregular heart rhythms. Monitoring and correcting potassium levels are crucial in preventing adverse cardiac events. The other options, though important, do not pose an immediate life-threatening risk compared to the low potassium level.

5. A client with liver cirrhosis and ascites is admitted with jaundice. Which laboratory value is most concerning to the nurse?

Correct answer: C

Rationale: An ammonia level of 80 mcg/dl is elevated and concerning in a client with liver cirrhosis, as it may indicate hepatic encephalopathy. Elevated ammonia levels can lead to neurological symptoms such as confusion, altered mental status, and even coma. Serum albumin, bilirubin, and prothrombin time are important in liver cirrhosis but are not the most concerning for acute neurological deterioration associated with hepatic encephalopathy.
