Question 1 of 5
A nurse is preparing to mix short-acting insulin with NPH insulin from two vials. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Inject air into the vial to withdraw the short-acting insulin. The rationale is to prevent the formation of a vacuum in the vial when withdrawing the insulin. By injecting air, it equalizes the pressure inside the vial, making it easier to withdraw the desired amount of insulin accurately. This step ensures that the correct dosage is obtained and minimizes the risk of contamination or air bubbles in the syringe.
Choices B, C, and D are incorrect:
B: Administer the insulin within 20 min of preparing it - This is not a necessary step for mixing short-acting insulin with NPH insulin; it is more important to ensure accurate dosage.
C: Ensure the NPH insulin is drawn into the syringe first - This is incorrect as the order of drawing the insulins does not affect their mixing or effectiveness.
D: Use two separate syringes to mix the insulin - This is unnecessary and increases the risk of errors in dosage measurement
Question 2 of 5
A nurse is reviewing the list of current medications for a client who has a new prescription for nitroglycerin. The nurse should identify that which of the following client medications is contraindicated for use with nitroglycerin?
Correct Answer: A
Rationale: The correct answer is A: Sildenafil. Nitroglycerin and sildenafil both cause vasodilation, leading to a severe drop in blood pressure when taken together, which can result in a life-threatening condition called hypotension. Gemfibrozil, lansoprazole, and diazepam do not have significant interactions with nitroglycerin and are safe to use together. It is important to avoid combining medications that have similar effects on the body to prevent adverse reactions.
Question 3 of 5
A nurse is reviewing the medication administration record for a client who has cancer and is receiving morphine via a PCA pump. Which of the following prescriptions should the nurse clarify with the provider?
Correct Answer: A
Rationale: The correct answer is A: Nalbuphine. Nalbuphine is a mixed opioid agonist-antagonist and may antagonize the effects of morphine, leading to decreased pain relief. The nurse should clarify this prescription with the provider to avoid potential interference with the effectiveness of morphine.
Summary of other choices:
B: Acetaminophen - Safe to administer with morphine for pain management.
C: Ondansetron - Used for nausea and vomiting, does not directly interact with morphine.
D: Insulin glargine - Used for diabetes management, does not interact with morphine.
Question 4 of 5
A nurse is assessing a client who has started taking theophylline. Which of the following client findings should indicate to the nurse that the medication is effective?
Correct Answer: B
Rationale: The correct answer is B: Decreased wheezing. Theophylline is a bronchodilator used to treat respiratory conditions like asthma or COPD by relaxing the muscles in the airways, reducing wheezing. Decreased wheezing indicates improved airflow and lung function, demonstrating the medication's effectiveness. Increased blood pressure (
A) is not a common effect of theophylline and may indicate a potential adverse reaction. Decreased urine output (
C) is not a typical indicator of theophylline effectiveness and could signify dehydration or kidney issues. Increased level of consciousness (
D) is not directly related to theophylline's action on the respiratory system.
Question 5 of 5
A nurse is assessing a client who is taking phenelzine and reports eating aged cheese. Which of the following is a manifestation of an interaction between the medication and the food?
Correct Answer: D
Rationale: The correct answer is D: Hypertension. Phenelzine is a monoamine oxidase inhibitor (MAOI) that can interact with tyramine-rich foods like aged cheese, leading to a hypertensive crisis. Tyramine in aged cheese can displace norepinephrine from nerve terminals, causing a sudden increase in blood pressure.
A: Somnolence is a common side effect of phenelzine but is not directly related to the interaction with aged cheese.
B: Diarrhea is not a typical manifestation of the interaction between phenelzine and aged cheese.
C: Bradycardia is not associated with the interaction between phenelzine and aged cheese; it is more commonly seen with other medications or conditions.
E, F, G: No further choices provided.
