Question 1 of 5
What drugs interact with tetracycline? (select all that apply)
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Liquid preparation that contains one or more chemical substance dissolved in a suitable solvent
Correct Answer: C
Rationale: A solution is a liquid preparation that contains one or more chemical substances dissolved in a suitable solvent. The solute (chemical substance) is evenly dispersed and mixed with the solvent, resulting in a homogenous mixture. Solutions are commonly used in medicine for oral administration, injections, topical treatments, and various other applications due to their ability to provide accurate dosing and rapid absorption into the body. decoction is a liquid derived from boiling plant material, fluid extract is a concentrated liquid extract of a substance, spirits are alcoholic solutions, and syrup is a viscous solution containing sugar.
Question 3 of 5
Which of the following is NOT an eicosanoid?
Correct Answer: D
Rationale: Kallidin is a peptide, specifically a kinin, and is not classified as an eicosanoid. Eicosanoids are a group of lipid mediators derived from arachidonic acid or other fatty acids, including prostaglandins, prostacyclin, thromboxane, and leukotrienes. Although kallidin also plays a role in inflammation and vasodilation like some eicosanoids, it is not part of the eicosanoid family.
Question 4 of 5
A patient is to receive a chemotherapy protocol that includes an alkylating agent, an antimetabolite, and an antitumor antibiotic. What is the nurse's best response when the patient asks the nurse why so much chemotherapy is needed?
Correct Answer: B
Rationale: Combination chemotherapy is used to target cancer cells at different stages of the cell cycle and through multiple mechanisms of action. Alkylating agents, antimetabolites, and antitumor antibiotics each work differently: alkylating agents damage DNA, antimetabolites interfere with DNA synthesis, and antitumor antibiotics inhibit RNA synthesis. By combining these drugs, the treatment can kill more cancer cells and reduce the likelihood of resistance. This approach maximizes tumor cell killing while minimizing the risk of relapse. Dose-limiting toxicities still exist, but the combination strategy allows for lower doses of each drug, reducing individual side effects.
Question 5 of 5
An older adult patient with a hip fracture became unresponsive 20 minutes after receiving morphine 3 mg intravenously. Which actions would the nurse take?
Correct Answer: C
Rationale: The patient's unresponsiveness after receiving morphine is likely due to opioid-induced respiratory depression, a potentially life-threatening side effect. The nurse should first assess the patient's airway, breathing, and circulation (ABCs) and call for additional assistance. Supporting breathing with a bag-valve-mask device is critical to ensure adequate oxygenation. Naloxone, an opioid antagonist, should be prepared to reverse the effects of morphine. Flumazenil (A) is used for benzodiazepine overdose, not opioids. Reporting a stroke (B) is incorrect because the symptoms are consistent with opioid toxicity, not a stroke. Explaining unresponsiveness as a desired outcome (D) is inappropriate and dangerous.
