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 3-year-old boy with a congenital heart defect is brought to the clinic by his mother. During the assessment, the mother asks the nurse why her child is at the 5th percentile for growth. What response is best for the nurse to provide?

• A. Does your child seem mentally slower than his peers also?
• B. His smaller size is probably due to the heart disease
• C. Haven't you been feeding him according to recommended daily allowances for children?
• D. You should not worry about the growth tables. They are only averages for children

Correct answer: B

Rationale: Heart disease can affect growth, leading to smaller size in children.

3. A client with cirrhosis is admitted with hepatic encephalopathy. Which laboratory value is most concerning?

• A. Serum ammonia level of 100 mcg/dl
• B. Bilirubin level of 3.0 mg/dl
• C. Prothrombin time of 18 seconds
• D. Serum sodium level of 135 mEq/L

Correct answer: A

Rationale: A serum ammonia level of 100 mcg/dl is most concerning in a client with hepatic encephalopathy. Elevated serum ammonia levels indicate significant liver dysfunction and an increased risk of worsening encephalopathy. Bilirubin level and prothrombin time are important in assessing liver function, but in the context of hepatic encephalopathy, elevated ammonia levels take precedence as they directly contribute to neurological symptoms. Serum sodium level, though important, is not the primary concern when managing hepatic encephalopathy.

4. The nurse is assessing a client with left-sided heart failure. Which assessment finding is most concerning?

• A. Jugular venous distention
• B. Peripheral edema
• C. Shortness of breath
• D. Crackles in the lungs

Correct answer: C

Rationale: Shortness of breath is the most concerning finding in a client with left-sided heart failure as it indicates worsening pulmonary congestion and impaired gas exchange. This symptom suggests that the client is experiencing significant difficulty in breathing and inadequate oxygenation, requiring immediate intervention. Jugular venous distention (Choice A) is often seen in right-sided heart failure, while peripheral edema (Choice B) and crackles in the lungs (Choice D) are common manifestations of left-sided heart failure but are not as acutely concerning as severe shortness of breath, which can rapidly progress to respiratory distress if not addressed promptly.

5. A client who has just returned from surgery is shivering uncontrollably. What is the best action for the nurse to take?

• A. Offer the client a warm blanket
• B. Apply warm blankets and monitor the client's temperature
• C. Place a warm blanket in the client's bed before transferring the client from the stretcher
• D. Administer a prescribed muscle relaxant

Correct answer: B

Rationale: Applying warm blankets and monitoring the client's temperature is the best action to manage postoperative shivering. Shivering after surgery can be a common response due to factors like exposure to cold, pain, or anesthesia effects. Providing warmth through blankets can help regulate the client's body temperature and alleviate shivering. Monitoring the client's temperature is essential to ensure it returns to a normal range. Option A is not as comprehensive as option B, which includes both providing warmth and monitoring the client. Option C is incorrect as it focuses on preparing the bed rather than addressing the client's immediate need for warmth. Option D is not appropriate without further assessment or prescription for a muscle relaxant to address shivering.
