1. What must the evening nurse do to facilitate the client's ECT treatment the next morning?
- A. Ensure the patient signs an informed consent form
- B. Administer evening medications
- C. Ensure the patient gets a good night's sleep
- D. Provide dietary restrictions as per ECT protocol
Correct answer: A
Rationale: For electroconvulsive therapy (ECT) treatment, obtaining informed consent is crucial before the procedure. This ensures the patient is aware of the risks, benefits, and alternatives to the treatment. Administering medications, ensuring rest, and dietary restrictions are important but not directly related to the specific requirement of obtaining informed consent for ECT. The correct answer, ensuring the patient signs an informed consent form, is essential to uphold the patient's autonomy and ensure they have the necessary information to make an informed decision about their treatment.
2. Which statement best describes electrolytes in intracellular and extracellular fluid?
- A. There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid
- B. There is an equal concentration of sodium and potassium in extracellular fluid
- C. There is a greater concentration of potassium in extracellular fluid and sodium in intracellular fluid
- D. There is an equal concentration of sodium and potassium between intracellular and extracellular fluid
Correct answer: A
Rationale: Electrolytes are distributed unequally between intracellular and extracellular fluids. Sodium concentration is higher in extracellular fluid, while potassium concentration is higher in intracellular fluid. Therefore, the correct answer is 'There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid.' Choices B, C, and D are incorrect because they do not accurately describe the typical distribution of sodium and potassium between intracellular and extracellular fluid.
3. Levothyroxine (Synthroid) is the drug of choice for thyroid replacement therapy in clients with hypothyroidism because:
- A. it is chemically stable, nonallergenic, and can be administered orally once a day.
- B. it is available in a wide range of concentrations to meet individual client requirements.
- C. it is a prodrug of T3.
- D. it has a long half-life.
Correct answer: A
Rationale: Levothyroxine (Synthroid) is the preferred medication for hypothyroidism due to its chemical stability, nonallergenic properties, and convenient once-daily oral administration. It is safe and effective with minimal side effects when appropriately dosed. Choice B is incorrect because while Levothyroxine is available in various concentrations, it is not the reason it is the drug of choice; the primary reason is its stability and nonallergenic nature. Choice C is wrong as Levothyroxine (T4) is not a prodrug of T3; it is converted to T3 in the body. Option D is inaccurate because Levothyroxine has a long half-life (around 7 days), enabling once-daily dosing, as opposed to a short half-life.
4. Signs of impaired breathing in infants and children include all of the following except:
- A. nasal flaring
- B. grunting
- C. seesaw breathing
- D. quivering lips
Correct answer: D
Rationale: Signs of impaired breathing in infants and children can manifest in various ways. Nasal flaring, grunting, and seesaw breathing are all indicative of respiratory distress in pediatric patients. Nasal flaring is the widening of the nostrils with breathing effort, grunting is a sound made during exhalation to try to keep the airways open, and seesaw breathing involves the chest moving in the opposite direction of the abdomen. However, quivering lips are not typically associated with impaired breathing in this context. Lip quivering is a distracter and not a common sign of respiratory distress in infants and children. Therefore, the correct answer is 'quivering lips.'
5. The nurse is caring for a client admitted with Class III/IV Pulmonary Hypertension. The nurse explains to the client that Lanoxin is being administered to the client in order to:
- A. Manage peripheral edema
- B. Improve right ventricular function
- C. Increase pulmonary pressure
- D. Constrict the pulmonary vessels
Correct answer: B
Rationale: The correct answer is to improve right ventricular function. Lanoxin, also known as digoxin, is a cardiac glycoside that works by slowing the heart rate and increasing myocardial contractility, especially in the ventricles. This action helps improve the efficiency of the heart's pumping function, particularly the right ventricle in conditions like pulmonary hypertension. Choice A, managing peripheral edema, is not directly related to Lanoxin's mechanism of action. Choice C, increasing pulmonary pressure, is incorrect as Lanoxin is not used to increase pressure in the pulmonary circulation. Choice D, constricting the pulmonary vessels, is incorrect as Lanoxin does not cause vasoconstriction in the pulmonary vessels but rather acts on the heart's contractility.
