A nurse is preparing to administer amoxicillin 75 mg/kg/day divided equally every 8 hr to a child who weighs 20 kg. Available is amoxicillin oral suspension 250 mg/5 mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 10 mL
Rationale: To calculate the dose, first, determine the total daily dose: 75 mg/kg/day x 20 kg = 1500 mg/day. Then, divide this by the number of doses per day (3) to get 500 mg per dose. Next, convert this to mL using the concentration of the oral suspension (250 mg/5 mL). 500 mg ÷ 250 mg/5 mL = 10 mL. Therefore, the correct answer is 10 mL.
Choice A is incorrect as it doesn't follow the correct calculation steps. Choices B-G are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the oral suspension.

A nurse in a provider's office is reviewing the laboratory findings of client who has been taking gemfibrozil for 3 months. Which of the following findings should the nurse expect?
- A. Increased serum creatinine
- B. Reduced serum calcium
- C. Increased Hgb
- D. Reduced triglycerides
Correct Answer: D
Rationale: The correct answer is D: Reduced triglycerides. Gemfibrozil is a lipid-lowering medication that works by decreasing triglyceride levels. The nurse should expect a reduction in triglycerides as a therapeutic effect of the medication. Option A (Increased serum creatinine) is incorrect as gemfibrozil typically does not affect creatinine levels. Option B (Reduced serum calcium) is incorrect as gemfibrozil does not impact calcium levels. Option C (Increased Hgb) is incorrect as gemfibrozil does not directly affect hemoglobin levels. Therefore, the nurse should anticipate a decrease in triglyceride levels as the expected finding in a client taking gemfibrozil.
A nurse in a clinic is caring for a client who was admitted for diazepam toxicity. Which of the following medications should the nurse anticipate administering?
- A. Vitamin K
- B. Calcium gluconate
- C. Protamine sulfate
- D. Flumazenil
Correct Answer: D
Rationale: The correct answer is D: Flumazenil. Flumazenil is a benzodiazepine receptor antagonist used to reverse the effects of benzodiazepine toxicity, such as diazepam. Administering Flumazenil in this case can help reverse the sedative and respiratory depressive effects of diazepam.
Incorrect choices:
A: Vitamin K is used for blood clotting disorders, not for benzodiazepine toxicity.
B: Calcium gluconate is used for treating calcium deficiencies, not for benzodiazepine toxicity.
C: Protamine sulfate is used to reverse the effects of heparin, not benzodiazepines.
In summary, Flumazenil is the appropriate choice to counter diazepam toxicity by antagonizing its effects on benzodiazepine receptors, while the other options are unrelated to managing benzodiazepine toxicity.
A nurse is collecting data from a client who is experiencing oxycodone toxicity. Which of the following findings should the nurse expect?
- A. Tachypnea
- B. Sedation
- C. Dilated pupils
- D. Tachycardia
Correct Answer: B
Rationale: The correct answer is B: Sedation. Oxycodone is an opioid that depresses the central nervous system, leading to sedation as a common manifestation of toxicity. Tachypnea (A) is more commonly associated with opioid withdrawal rather than toxicity. Dilated pupils (C) are more indicative of stimulant toxicity, not opioids. Tachycardia (D) is unlikely with oxycodone toxicity due to its depressant effects on the cardiovascular system. Other choices are not relevant to oxycodone toxicity.
A nurse is reinforcing teaching with a client who has pancreatitis and a new prescription for pancrelipase. Which of the following statements by the client indicates an understanding of the teaching?
- A. I will take this medication whole.
- B. I can expect this medication to cure the pancreatitis.
- C. I should discontinue the medication if I develop fatty stools.
- D. I will take this medication at bedtime.
Correct Answer: A
Rationale: The correct answer is A: "I will take this medication whole." This is correct because pancrelipase should be taken whole to ensure the proper release of enzymes in the small intestine for digestion. Option B is incorrect because pancrelipase does not cure pancreatitis but helps with digestion. Option C is incorrect because fatty stools are expected side effects of pancrelipase and not a reason to discontinue the medication. Option D is incorrect because pancrelipase should be taken with meals or snacks, not specifically at bedtime.
A nurse is reinforcing teaching with a client who has a new prescription for naproxen. Which of the following is a potential adverse effect that the nurse should instruct the client to report to the provider?
- A. Increased energy levels
- B. Black, tarry stools
- C. Improved appetite
- D. Mild headache
Correct Answer: B
Rationale: The correct answer is B: Black, tarry stools. This is a potential adverse effect of naproxen, indicating gastrointestinal bleeding. It is crucial to report this to the provider immediately to prevent serious complications. Increased energy levels (A), improved appetite (C), and mild headache (D) are common side effects of naproxen and do not require immediate medical attention. The priority is to address potential serious adverse effects like gastrointestinal bleeding.
