A patient with a history of malaria who is being treated with chloroquine is in the clinic for a follow-up visit. What should the nurse advise the patient to do?

Correct Answer: A

Rationale: Chloroquine can cause retinopathy, so patients should be advised to report any visual changes promptly. Taking the medication with milk is not necessary. Sunlight avoidance is not specifically required for chloroquine, though it may cause photosensitivity in some patients. Increasing fluid intake is not a specific recommendation for chloroquine use.

Correct Answer: A

Rationale: Colchicine is the medication of choice for treating acute gout attacks due to its anti-inflammatory properties. It works by inhibiting microtubule polymerization, which reduces the migration of neutrophils to the inflamed joint, thereby alleviating pain and swelling. Allopurinol and probenecid are used for long-term management of gout to prevent future attacks by lowering uric acid levels, but they are not effective during an acute attack. Sulfinpyrazone is another uricosuric agent used for chronic management. Therefore, colchicine is the most appropriate medication for acute gout treatment, and nurses should be familiar with its use and monitoring.

Correct Answer: D

Rationale: Lithium is commonly used to treat bipolar disorder, a mental health condition characterized by mood swings that range from depressive lows to manic highs. Lithium helps stabilize these mood swings by altering the levels of certain chemicals in the brain. It is not used to treat hypertension, nausea, or thyroid disorders.

Correct Answer: D

Rationale: The specificity theory of pain proposes that there is a specific pain system in the body that is responsible for detecting and transmitting pain signals. According to this theory, specific pain receptors exist that are sensitive only to pain stimuli and are separate from other sensory receptors for touch, temperature, or pressure. When tissue damage or injury occurs, these pain receptors are activated, and they send signals through specific pain pathways to the brain, resulting in the sensation of pain. The specificity theory suggests that pain is a distinct sensory modality with its own dedicated system, separate from other sensory modalities.

Correct Answer: A

Rationale: The official name of a drug used in the United States Pharmacopeia-National Formulary (USP-NF) is the generic name. The generic name is the non-proprietary name of a drug, which is based on its chemical structure. It is important to distinguish the generic name from other types of names like the brand name (specific name given by the manufacturer) or proprietary name (registered trademark name owned by a pharmaceutical company). In the USP-NF, the generic name is used to refer to the drug in a standardized and universally recognized manner. This helps ensure clarity and consistency in the identification and communication of drug information.
