Nursing Elites

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

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

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 chronic heart failure is admitted with shortness of breath and a new onset of confusion. Which intervention should the nurse implement first?

• A. Obtain a neurological assessment.
• B. Administer oxygen therapy.
• C. Monitor the client's urine output.
• D. Obtain an electrocardiogram (ECG).

Correct answer: A

Rationale: The correct answer is to obtain a neurological assessment. In a client with chronic heart failure presenting with confusion, the priority is to assess neurological status to rule out potential causes such as hypoxia or other complications. Administering oxygen therapy (Choice B) is important but assessing the neurological status takes precedence in this scenario. Monitoring urine output (Choice C) and obtaining an ECG (Choice D) may be necessary but are not the initial priority when a client presents with confusion alongside shortness of breath.

3. In a client with cirrhosis admitted with ascites and jaundice, which clinical finding requires immediate intervention?

• A. Peripheral edema
• B. Confusion and altered mental status
• C. Increased abdominal girth
• D. Yellowing of the skin

Correct answer: B

Rationale: Confusion and altered mental status in a client with cirrhosis and associated ascites and jaundice are indicative of hepatic encephalopathy, a serious complication that requires immediate intervention. This condition can progress rapidly and lead to coma if not addressed promptly. Peripheral edema (choice A) and increased abdominal girth (choice C) are common manifestations of fluid retention in cirrhosis but may not require immediate intervention unless severe. Yellowing of the skin (choice D) is a classic sign of jaundice, which is already known in this client and may not necessitate immediate intervention unless associated with other concerning symptoms.

4. The nurse provides feeding tube instructions to the wife of a client with end-stage cancer. The client's wife performs a return demonstration correctly but begins crying and tells the nurse, 'I just don't think I can do this every day.' The nurse should direct further teaching strategies toward which learning domain?

• A. Cognitive.
• B. Affective.
• C. Comprehension.
• D. Psychomotor.

Correct answer: B

Rationale: The correct answer is B: Affective. The affective domain involves feelings and emotions, which are significant factors in the wife’s ability to cope and perform the required care. In this scenario, the wife's emotional response indicates a need for further support and teaching strategies to address her emotional concerns and build her confidence. Choices A, C, and D are incorrect because the issue at hand is not purely cognitive (knowledge), comprehension (understanding), or psychomotor (physical skills), but rather an emotional response that falls under the affective domain.

5. A client with a history of chronic heart failure is admitted with shortness of breath. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Chest X-ray
• B. Arterial blood gases (ABGs)
• C. Echocardiogram
• D. Electrocardiogram (ECG)

Correct answer: C

Rationale: The correct answer is an echocardiogram. This diagnostic test is crucial in assessing ventricular function and identifying the cause of shortness of breath in a client with heart failure. It provides valuable information about the heart's structure, function, and blood flow. While a chest X-ray may show signs of heart failure, it does not directly assess cardiac function like an echocardiogram does. Arterial blood gases (ABGs) are useful to evaluate oxygenation and acid-base balance but do not provide information specific to heart function. An electrocardiogram (ECG) assesses the heart's electrical activity and rhythm, which is important but may not provide the detailed structural information needed in this scenario.
