Question 1 of 5
Component of local anesthetic solution which serves as vasoconstrictor:
Correct Answer: B
Rationale: Levonordefrin is a vasoconstrictor that is commonly added to local anesthetic solutions to help reduce bleeding and prolong the anesthetic effect by constricting blood vessels at the injection site. Methylparaben, sodium bisulfite, and sodium pyrosulfite are not vasoconstrictors and do not serve this specific function in local anesthetic solutions.
Question 2 of 5
Which of the following contributes most to the debilitation of an individual during a course of chemotherapy?
Correct Answer: D
Rationale: Pain is a significant contributor to the debilitation of an individual during a course of chemotherapy. The side effects of chemotherapy often include pain, which can be caused by treatment procedures, side effects of medication, or the cancer itself. Pain can lead to decreased mobility, appetite, and overall quality of life, impacting the individual's ability to cope with treatment and recovery. Managing pain effectively is crucial in improving the patient's comfort and overall well-being during chemotherapy. While diarrhea, alopecia, and constipation are common side effects of chemotherapy, they do not typically contribute as significantly to the debilitation of an individual compared to pain.
Question 3 of 5
A pregnant woman is experiencing hypertension. The nurse knows that which drug is commonly used for a pregnant patient who is experiencing hypertension?
Correct Answer: D
Rationale: Methyldopa is the preferred antihypertensive medication for pregnant women experiencing hypertension. It has been extensively studied and considered safe for both the mother and the fetus. Methyldopa has been shown to effectively lower blood pressure in pregnant women without causing harm to the developing fetus. Other antihypertensive medications, such as Enalapril (Vasote) and Hydrochlorothiazide (HydroDIURIL), are contraindicated during pregnancy as they can cause harm to the fetus. Mannitol (Osmitrol) is an osmotic diuretic primarily used for reducing intracranial pressure or treating cerebral edema, not for hypertension in pregnancy. Therefore, Methyldopa is the right choice for a pregnant patient with hypertension.
Question 4 of 5
A 26-year-old man with a chronic cough takes codeine for cough suppression. He presents to his primary care physician for follow-up. The patient admits to taking this medication three times daily even when he does not have symptoms. The treating physician must be concerned about which of the following effects?
Correct Answer: A
Rationale: Codeine, an opioid, risks addiction with frequent use. Diarrhea opposes its constipating effect. Euphoria and anxiety are possible but less concerning. Sweating (E) is minor. Addiction potential drives monitoring, given his overuse pattern.
Question 5 of 5
A client with benign prostatic hyperplasia is to receive finasteride (Proscar). The nurse understands that this drug works by
Correct Answer: B
Rationale: Finasteride (Proscar), a 5-alpha reductase inhibitor, shrinks the prostate in BPH by reducing dihydrotestosterone, easing urinary obstruction. Smooth muscle relaxation is for ED drugs like sildenafil. It lowers DHT, not testosterone, and doesn't stimulate RNA synthesis. Prostate shrinkage is its core action, distinct from other mechanisms.
