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 kidney disease (CKD) is scheduled for a renal biopsy. Which laboratory value is most concerning?

• A. Serum potassium of 5.5 mEq/L
• B. Serum creatinine of 1.5 mg/dl
• C. Serum creatinine of 2.5 mg/dl
• D. White blood cell count of 8,000/mm3

Correct answer: C

Rationale: A serum creatinine level of 2.5 mg/dl is the most concerning laboratory value in a client with chronic kidney disease scheduled for a renal biopsy. An elevated serum creatinine level indicates impaired kidney function, which is critical information before performing a renal biopsy. Option A (Serum potassium of 5.5 mEq/L) may be concerning for hyperkalemia but is not directly related to the renal biopsy procedure. Option B (Serum creatinine of 1.5 mg/dl) is within normal limits, suggesting relatively normal kidney function. Option D (White blood cell count of 8,000/mm3) is within the normal range and not directly related to the renal biopsy procedure or CKD management.

3. The nurse weighs a 6-month-old infant during a well-baby check-up and determines that the baby's weight has tripled compared to the birth weight of 7 pounds 8 ounces. The mother asks if the baby is gaining enough weight. What response should the nurse offer?

• A. Your baby is gaining weight right on schedule
• B. What food does your baby usually eat in a normal day?
• C. The baby is below the normal percentile for weight gain
• D. What was the baby's weight at the last well-baby check-up?

Correct answer: A

Rationale: The correct answer is A: 'Your baby is gaining weight right on schedule.' Tripling of birth weight by 6 months is a normal growth pattern in infants, indicating appropriate weight gain and development. Choice B is unrelated to the question as it focuses on the baby's diet rather than addressing the weight gain concern. Choice C is incorrect as tripling the birth weight is considered a healthy growth pattern, not below normal percentile. Choice D is irrelevant to the mother's question about the adequacy of weight gain.

4. The nurse observes an unlicensed assistive personnel (UAP) using an alcohol-based gel hand cleaner before performing catheter care. The UAP rubs both hands thoroughly for 2 minutes while standing at the bedside. Which action should the nurse take?

• A. Encourage the UAP to remain in the client's room until the procedure is completed.
• B. Explain that the hand rub can be completed in less than 2 minutes.
• C. Inform the UAP that handwashing helps to promote better asepsis.
• D. Determine why the UAP was not wearing gloves in the client's room.

Correct answer: B

Rationale: The correct answer is B. Explaining that hand rubs can be effective with less time allows the UAP to perform the procedure more efficiently while maintaining asepsis. Choice A is incorrect because the UAP does not need to remain in the client's room until the procedure is completed. Choice C is incorrect as the UAP was using an alcohol-based gel hand cleaner, not handwashing. Choice D is incorrect as the scenario does not mention any issue with glove usage, so it is not relevant to the situation at hand.

5. During the initial newborn assessment, the nurse finds that a newborn's heart rate is irregular. Which intervention should the nurse implement?

• A. Notify the pediatrician immediately.
• B. Teach the parents about congenital heart defects.
• C. Document the finding in the infant's record.
• D. Apply oxygen via nasal cannula at 3 L/min.

Correct answer: C

Rationale: The correct intervention when a nurse finds an irregular heart rate in a newborn is to document the finding in the infant's record. An irregular heart rate is a common occurrence in newborns and does not necessarily require immediate medical intervention. Notifying the pediatrician immediately is unnecessary unless there are other concerning symptoms. Teaching the parents about congenital heart defects is not the priority in this situation. Applying oxygen via nasal cannula at 3 L/min is not indicated for an irregular heart rate without further assessment or medical indication.
