What is the term used for a well understood drug model with which other drugs in its representative class are compared?

Antibiotics

Pharmacologic Drug

Prototype Drug

Therapeutic Drug

Answer and Explanation

The Correct Answer is C

Choice A reason: This is incorrect. Antibiotics are not a term for a drug model, but a class of drugs that are used to treat bacterial infections. Antibiotics can have different chemical structures, mechanisms of action, and modes of action. For example, penicillin is a prototype drug of the beta lactam antibiotics, which inhibit the synthesis of bacterial cell walls¹.

Choice B reason: This is incorrect. Pharmacologic drug is not a term for a drug model, but a general term for any substance that has a physiological effect on the body. Pharmacologic drugs can belong to different classes, such as analgesics, antihistamines, or antivirals. For example, aspirin is a prototype drug of the nonsteroidal anti-inflammatory drugs (NSAIDs), which reduce pain, inflammation, and fever.

Choice C reason: This is correct. Prototype drug is the term used for a well understood drug model with which other drugs in its representative class are compared. A prototype drug is an individual drug that has similar chemical structure, mechanism of action, and mode of action as other drugs in its class. A prototype drug is often the first developed or the most important drug in its class, and is used as a reference for comparison. For example, morphine is a prototype drug of the opioid analgesics, which relieve pain by binding to opioid receptors in the brain and spinal cord.

Choice D reason: This is incorrect. Therapeutic drug is not a term for a drug model, but a term for any drug that is used to treat or prevent a disease or disorder. Therapeutic drugs can belong to different classes, such as antibiotics, antihypertensives, or antidepressants. For example, metformin is a prototype drug of the biguanide antidiabetic drugs, which lower blood glucose levels by reducing glucose production in the liver and increasing glucose uptake in the muscles.

Correct Answer is D

Explanation

Choice A reason: Allergy is an immune mediated reaction to a substance that causes symptoms such as rash, itching, swelling, or anaphylaxis. It is not related to the duration or effectiveness of the medication. The patient does not report any signs of allergy to the opioids.

Choice B reason: Addiction is a chronic and compulsive disorder that involves seeking and using a substance despite harmful consequences. It is characterized by loss of control, craving, and impaired functioning. The patient does not show any signs of addiction to the opioids, such as increasing the dose, obtaining the medication illegally, or neglecting other responsibilities.

Choice C reason: Withdrawal is a syndrome that occurs when a substance is abruptly discontinued or reduced after prolonged use. It causes physical and psychological symptoms such as anxiety, agitation, sweating, nausea, or tremors. The patient does not experience any signs of withdrawal from the opioids, as they are still taking the medication as prescribed.

Choice D reason: Tolerance is a phenomenon that occurs when a substance loses its effectiveness over time due to repeated exposure. It requires higher doses or more frequent administration to achieve the same effect. The patient reports a sign of tolerance to the opioids, as they feel that the medication does not work as well anymore. The nurse should assess the patient's pain level, monitor the opioid dose, and consult with the prescriber about possible adjustments or alternatives.

A. Constipation B. Flatulence C. Headache D. Palpitations

Correct Answer is A

Explanation

Choice A reason: This is correct. Constipation is a common side effect of aluminum hydroxide, as it reduces the motility of the gastrointestinal tract. The nurse should advise the client to report this symptom and to increase their fluid and fiber intake to prevent it.

Choice B reason: This is incorrect. Flatulence is not a common side effect of aluminum hydroxide. It may be caused by other factors, such as diet, swallowing air, or bacterial overgrowth in the intestines.

Choice C reason: This is incorrect. Headache is not a common side effect of aluminum hydroxide. It may be caused by other factors, such as stress, dehydration, or caffeine withdrawal.

Choice D reason: This is incorrect. Palpitations are not a common side effect of aluminum hydroxide. They may be caused by other factors, such as anxiety, heart problems, or medication interactions.
