Question 1 of 5
A nurse is providing teaching to a client who reports smoking 3 packs of cigarettes per day and has a prescription for nicotine gum. Which of the following instructions should the nurse include in the teaching?
Correct Answer: A
Rationale:
Correct Answer: A - Chew the gum slowly over 30 minutes.
Rationale: Chewing nicotine gum slowly over 30 minutes allows for proper absorption of nicotine through the oral mucosa, mimicking the slow release of nicotine from smoking. This helps reduce cravings and withdrawal symptoms effectively.
Summary of incorrect choices:
B: Do not chew more than 40 pieces of gum per day - While there is a recommended maximum amount of nicotine gum per day, this specific instruction does not address proper chewing technique.
C: Allow 9 months for the gum to achieve the therapeutic effect - This is inaccurate as nicotine gum provides immediate relief from cravings and withdrawal symptoms.
D: Drink a glass of water 5 minutes before chewing the gum - While staying hydrated is important, this instruction does not directly relate to the proper use of nicotine gum.
Question 2 of 5
A nurse is caring for a client who has a life-threatening ventricular dysrhythmia. Which of the following medications should the nurse anticipate administering?
Correct Answer: D
Rationale: The correct answer is D: Amiodarone. Amiodarone is an antiarrhythmic medication commonly used to treat life-threatening ventricular dysrhythmias. It works by prolonging the action potential duration and refractory period of cardiac muscle cells, thereby stabilizing the heart's electrical activity. Digoxin (
A) is not typically used for ventricular dysrhythmias. Dopamine (
B) is a vasopressor used for hypotension, not dysrhythmias. Verapamil (
C) is a calcium channel blocker, which is contraindicated in ventricular dysrhythmias.
Therefore, the nurse should anticipate administering amiodarone to treat the client's life-threatening ventricular dysrhythmia.
Question 3 of 5
A nurse is planning to administer medications to a client who weighs 198 lb. The prescription reads, 'filgrastim 5 mcg/kg, subcutaneous, daily.' Available is filgrastim 300 mcg/mL. How many mL should the nurse plan to give with each dose?
Correct Answer: A
Rationale:
To calculate the dose of filgrastim, we first need to convert the client's weight from pounds to kilograms. 198 lb is approximately 89.9 kg.
Then, we multiply the weight by the prescribed dose (5 mcg/kg) to get the total dose required, which is 449.5 mcg. Next, we divide the total dose by the concentration of the available filgrastim (300 mcg/mL) to find the volume needed, which is 1.5 mL.
Therefore, the correct answer is A.
Choices B, C, and D are incorrect as they do not match the calculated dose based on the client's weight and the prescribed dosage of filgrastim.
Question 4 of 5
A nurse is caring for a client who is taking lithium and reports starting a new exercise program. The nurse should assess the client for which of the following electrolyte imbalances?
Correct Answer: B
Rationale: The correct answer is B: Hyponatremia. When a client taking lithium starts a new exercise program, they may sweat more, leading to sodium loss. This can result in hyponatremia, which is a common electrolyte imbalance associated with lithium therapy. Symptoms of hyponatremia include confusion, headache, muscle weakness, and nausea.
A: Hypokalemia is not typically associated with lithium therapy or exercise programs.
C: Hypocalcemia is not a common electrolyte imbalance seen with lithium therapy or exercise.
D: Hypomagnesemia is also not a common electrolyte imbalance related to lithium or exercise.
Therefore, choice B is the most appropriate electrolyte imbalance to assess in this scenario.
Question 5 of 5
A nurse in an emergency department is assessing a client who received epinephrine. Which of the following findings should the nurse report as an adverse effect of epinephrine?
Correct Answer: A
Rationale: The correct answer is A: Chest pain. Epinephrine is a sympathomimetic medication that can cause vasoconstriction leading to increased cardiac workload, potentially resulting in chest pain. Bradycardia (
B) is unlikely as epinephrine typically increases heart rate. Hypoglycemia (
C) is a potential adverse effect but not specific to epinephrine. Respiratory depression (
D) is not a common side effect of epinephrine.
