A nurse is reinforcing discharge teaching about sublingual nitroglycerin with a client who has angina. Which of the following statements indicates an understanding of the instructions?
"I am going to take the medication with food.”
"I understand that the medication can slow my heart rate.”
"I should feel the effects of the medication within 5 minutes.”
"I will take the medication every 10 minutes until the pain goes away.”
The Correct Answer is C
Choice A rationale:
The statement about taking the medication with food is incorrect. Nitroglycerin sublingual tablets should not be taken with food. They work much faster when absorbed through the lining of the mouth.
Choice B rationale:
The statement that the medication can slow the heart rate is incorrect. Nitroglycerin does not slow the heart rate. In fact, it can cause a reflex tachycardia, where the heart rate increases.
Choice C rationale:
The statement that the effects of the medication should be felt within 5 minutes is correct. This indicates an understanding of the instructions.
Choice D rationale:
Taking the medication every 10 minutes until the pain goes away is incorrect. Nitroglycerin sublingual tablets usually give relief in 1 to 5 minutes. However, if the pain is not relieved, a second tablet can be taken 5 minutes after the first tablet. If the pain continues for another 5 minutes, a third tablet may be used. Taking the medication every 10 minutes could lead to an overdose.

Correct Answer is A
Explanation
Choice A rationale:
Administering an IV fluid bolus can help increase blood volume and thus increase blood pressure, which can alleviate symptoms of dizziness and lightheadedness. This is a common side effect of ramipril, especially after the first dose.
Choice B rationale:
Naloxone is an opioid antagonist and is not relevant in this context. It’s used to reverse the effects of opioid overdose, not to treat symptoms associated with antihypertensive medications.
Choice C rationale:
Diphenhydramine is an antihistamine used to treat allergic reactions or insomnia, not symptoms associated with antihypertensive medications.
Choice D rationale:
Administering 15 g of carbohydrates would be appropriate for a hypoglycemic patient, not for a patient experiencing dizziness and lightheadedness due to antihypertensive medication.
Correct Answer is ["1"]
Explanation
Step 1: Convert the child's weight from pounds to kilograms.
44 pounds / 2.2 pounds/kg = 20 kg
Step 2: Calculate the child's total daily dose of gentamicin.
20 kg * 6 mg/kg/day = 120 mg/day
Step 3: Divide the child's total daily dose of gentamicin by the number of doses per day.
120 mg / 3 doses/day = 40 mg/dose
Step 4: Calculate the volume of gentamicin to be administered with each dose.
40 mg / 40 mg/mL = 1 mL/dose
Step 5: Round the answer to the nearest whole number and add a leading zero if necessary.
1 mL/dose = 1 mL/dose
Answer: 1 mL with each dose.
