Question 1 of 5
The process by which a gas is released in a certain substance when added with water
Correct Answer: A
Rationale: The term "effervescent" refers to the process of a gas being released from a substance when added to water. This is commonly observed when certain tablets or powders are added to water, resulting in the production of bubbles or fizz. Mucilage refers to a thick, sticky substance, while spirits typically refer to alcoholic beverages. Collyria are eye drops, and collodion is a solution used in photography and medicine.
Therefore, the correct term for the described process is "effervescent."
Question 2 of 5
A patient is scheduled to receive high-dose cyclophosphamide via an intravenous infusion as treatment for cancer. Which will be most important for the nurse to include when teaching the patient about cyclophosphamide?
Correct Answer: B
Rationale: Cyclophosphamide can cause hemorrhagic cystitis, a serious side effect resulting from the irritation of the bladder lining by its metabolites.
To prevent this, patients must maintain high fluid intake (at least 2 liters per day) to dilute the urine and flush out the bladder. While emptying the bladder regularly is important, it is secondary to ensuring adequate hydration. Limiting fluid intake is contraindicated, as it increases the risk of bladder toxicity. An indwelling urinary catheter is not routinely required unless the patient has urinary retention.
Question 3 of 5
What is the therapeutic use of levothyroxine?
Correct Answer: C
Rationale: Levothyroxine is a synthetic form of the thyroid hormone thyroxine and is commonly used for the treatment of hypothyroidism. Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormone to meet the body's needs, leading to various symptoms such as fatigue, weight gain, cold intolerance, and depression. By providing exogenous levothyroxine, the medication helps restore normal thyroid hormone levels in the body, thereby alleviating the symptoms of hypothyroidism and restoring normal hormonal balance. It is important to monitor thyroid hormone levels regularly when on levothyroxine therapy to ensure optimal dosing and maintenance of normal thyroid function.
Question 4 of 5
Which of the following diuretics inhibits sodium reabsorption in the kidneys while saving K+ and Hydrogen ions?
Correct Answer: A
Rationale: Spironolactone is a potassium-sparing diuretic, which belongs to the aldosterone receptor antagonists. It works by inhibiting aldosterone activity in the distal convoluted tubule and collecting ducts of the kidney. Aldosterone promotes sodium reabsorption in exchange for potassium and hydrogen ions. By blocking aldosterone, Spironolactone allows for increased excretion of sodium while retaining potassium and hydrogen ions, making it a suitable choice for patients who need to maintain potassium levels or are at risk for hypokalemia.
Question 5 of 5
The patient is discharged home and returns to the emergency department 4 days later. The patient is admitted to the ICU with acute decompensated HF with dyspnea at rest. The nurse anticipates administration of which medication?
Correct Answer: D
Rationale: Nesiritide, also known as Natrecor, is a medication commonly used in the treatment of acute decompensated heart failure (ADHF) with dyspnea at rest. It is a recombinant form of B-type natriuretic peptide (BNP) which helps to improve cardiac function and alleviate symptoms of heart failure, such as dyspnea. Nesiritide works by promoting vasodilation and increasing diuresis, which can help reduce the workload on the heart and improve cardiac output.
Therefore, in the case of a patient with acute decompensated heart failure and dyspnea at rest, the nurse would anticipate the administration of Nesiritide to help improve the patient's condition.
