A patient who is addicted to heroin is admitted to the hospital for treatment of an infection. The patient is prescribed methadone (Dolophine) as part of a detoxification program. What is the rationale for using methadone in this patient?

The correct answer is choice C) Chest pain.

This is because chest pain can be a sign of a serious cardiovascular event, such as a heart attack or stroke, which can be fatal.

Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that belongs to the class of cyclooxygenase-2 (COX-2) inhibitors.These drugs can increase the risk of cardiovascular thrombotic events, especially in patients with a history of heart disease or risk factors.

Therefore, the nurse should instruct the client to report chest pain immediately and seek emergency medical attention.

Choice A) Constipation is wrong because it is not a common or serious side effect of celecoxib.

Constipation can be caused by many factors, such as diet, dehydration, lack of exercise, or other medications.It can be managed by increasing fluid and fiber intake, using laxatives or stool softeners as needed, and consulting a doctor if it persists or worsens.

Choice B) Nausea is wrong because it is a common but mild side effect of celecoxib that usually goes away with time or can be reduced by taking the medication with food or milk.

Nausea is not a sign of a serious adverse reaction and does not require immediate medical attention.

Choice D) Headache is wrong because it is also a common but mild side effect of celecoxib that can be treated with over-the-counter pain relievers, such as acetaminophen or ibuprofen.

However, the client should avoid taking aspirin or other NSAIDs with celecoxib, as this can increase the risk of gastrointestinal bleeding and ulcers

The correct answer is choice A. Serum calcium.Etidronate is a bisphosphonate that inhibits bone resorption and reduces the risk of skeletal complications in patients with cancer-related bone pain.However, it can also cause hypocalcemia (low serum calcium levels) as a side effect, which can lead to muscle spasms, numbness, tingling, seizures, and cardiac arrhythmias.

Therefore, the nurse should monitor the patient’s serum calcium levels regularly and supplement with calcium and vitamin D if needed.

Choice B. Serum potassium is wrong because etidronate does not affect potassium levels.Potassium is mainly regulated by the kidneys and can be altered by renal impairment, dehydration, acid-base imbalance, or medications such as diuretics or potassium-sparing agents.

Choice C. Serum creatinine is wrong because etidronate does not affect creatinine levels.

Creatinine is a waste product of muscle metabolism that is excreted by the kidneys.It reflects the glomerular filtration rate (GFR) and can be elevated in renal dysfunction or dehydration.

Choice D. Serum albumin is wrong because etidronate does not affect albumin levels.

Albumin is a protein that is synthesized by the liver and helps maintain fluid balance and transport substances in the blood.It can be decreased in liver disease, malnutrition, inflammation, or protein-losing conditions.
