Question 1 of 5
Hydrochlorothiazide is classified as a
Correct Answer: C
Rationale: Hydrochlorothiazide is a diuretic medication commonly used to treat hypertension (high blood pressure) and edema (fluid retention). It works by increasing the amount of water and salt that the kidneys remove from the blood, leading to decreased blood volume and lower blood pressure. Diuretics like hydrochlorothiazide are not used to treat inflammation, arrhythmias, or fungal infections, making option C the correct classification for this medication.
Question 2 of 5
Sodium bisulfite is a component of local anesthetic solution whose function is
Correct Answer: B
Rationale: Sodium bisulfite is commonly added to local anesthetic solutions as a vasoconstrictor. Vasoconstrictors work by constricting blood vessels at the site of injection. This helps to reduce blood flow to the area, which in turn decreases bleeding, prolongs the anesthetic effect, and reduces the risk of systemic toxicity by slowing the absorption of the anesthetic into the bloodstream. Sodium bisulfite specifically acts as a vasoconstrictor in local anesthetics to enhance the overall effectiveness of the numbing agent.
Question 3 of 5
All are true for superinfections, except:
Correct Answer: A
Rationale: Superinfections are secondary infections that occur as a result of disrupting the normal balance of microorganisms in the body, often due to prolonged or broad-spectrum antibiotic use. They can involve the emergence of resistant strains or the overgrowth of opportunistic pathogens. Therefore, superinfections are more likely to occur with prolonged antibiotic use or broad-spectrum antibiotics that disrupt the normal flora of the body. It is less common for superinfections to occur with narrow spectrum antibiotics, as they target a more limited range of bacteria and are less likely to disrupt the overall microbial balance in the body.
Question 4 of 5
One hour after receiving intravenous morphine sulfate, a patient reports generalized itching. The nurse assesses the patient and notes clear breath sounds, no rash, respirations of 14 breaths per minute, a heart rate of 68 beats per minute, and a blood pressure of 110/70 mm Hg. Which action will the nurse take?
Correct Answer: D
Rationale: The correct action for the nurse to take in this situation is to prepare an epinephrine injection in case of an anaphylactic reaction. The patient's presentation of generalized itching could be a sign of an allergic reaction to morphine sulfate. It is important to be prepared for an anaphylactic reaction, which could potentially be life-threatening. Having epinephrine readily available allows for quick administration if needed to treat the allergic reaction. Reassuring the patient is also appropriate, but the priority in this situation is to be prepared for a possible serious allergic reaction. Administering naloxone to reverse opioid overdose is not indicated based on the patient's current vital signs and symptoms. Having resuscitation equipment available at the bedside is always a good practice, but preparing for an anaphylactic reaction takes precedence in this scenario.
Question 5 of 5
The nurse is caring for a 55-year-old patient receiving metoprolol (Lopressor). What statement by the patient would lead the nurse to believe that he needs additional instruction?
Correct Answer: B
Rationale: OTC medications can interact to increase or decrease the effects of antiadrenergic drugs. Antacids decrease the effects of beta-adrenergic blocking drugs. Decreased antihypertensive effects result when taken with ibuprofen. Other options reflect correct statements and would not indicate that the patient would need further instruction. The nurse should educate the patient about potential drug interactions and the importance of consulting their healthcare provider before taking OTC medications.
