Question 1 of 5
A patient will be taking niacin as part of antilipemic therapy. What is the best way to avoid problems with flushing or pruritus?
Correct Answer: D
Rationale: The best way to avoid problems with flushing or pruritus when taking niacin for antilipemic therapy is to take the medication with a full glass of water on an empty stomach. This method helps to minimize the chances of flushing or itching commonly associated with niacin therapy. Niacin can cause flushing by dilating blood vessels, leading to redness, warmth, and itching of the skin. Taking it on an empty stomach with water can help reduce the intensity of these side effects. Starting with a low initial dose and then gradually increasing it can also help to reduce flushing and other adverse effects associated with niacin therapy.
Question 2 of 5
The client receives albuterol (Proventil) via inhaler. He asks the nurse why he can't just take a pill. What is the best response by the nurse?
Correct Answer: A
Rationale: Albuterol's inhalation targets lungs directly, with rapid absorption for quick relief (minutes vs. hours for oral). Pills work but slower. Side effects differ, not the reason. Efficacy varies by route. A explains pharmacokinetics, making it the best response.
Question 3 of 5
Fundamental action of vaccines :
Correct Answer: C
Rationale: The fundamental action of vaccines is prophylaxis, which means the prevention of disease. Vaccines are designed to stimulate the body's immune system to recognize and fight specific pathogens before they cause infection or illness. By introducing a weakened or inactivated form of the pathogen to the body, vaccines trigger an immune response and teach the immune system how to recognize and destroy the pathogen in the future. Through prophylaxis, vaccines help protect individuals from getting sick with certain diseases.
Question 4 of 5
A 52-year-old man with chronic low back pain following an automobile accident desires pain relief. He has significant gastroesophageal reflux and abdominal pain. Which of the following agents may improve his pain but worsen his gastrointestinal symptoms?
Correct Answer: D
Rationale: Chronic pain with GERD limits NSAID use. Naproxen sodium -relieves pain but worsens GI symptoms via COX-1 inhibition, increasing acid and ulcers. Trisalicylate and Celecoxib are GI-sparing. Ketorolac is short-term. Salsalate (E) is milder. Naproxen fits the risk profile.
Question 5 of 5
A nurse working in an obstetric practice should consider which fact when discussing medication use with pregnant patients?
Correct Answer: A
Rationale: Pregnancy boosts lung perfusion, increasing inhaled drug absorption (e.g., anesthetics), a pharmacokinetic shift to note. Excretion may slow later, but not universally. Oral absorption isn't broadly reduced-GI changes vary. Avoiding all drugs is impractical-some conditions need treatment. Inhaled absorption informs safe use.
