Question 1 of 5
The client receives alendronate (Fosamax) as treatment for osteoporosis. Which symptoms, caused by an adverse effect of the medication, does the nurse teach should be reported to the physician?
Correct Answer: C
Rationale: Alendronate's rare eye effects-vision changes, photophobia-signal inflammation, needing report, per safety. Ringing ears, hot skin, or spasms aren't linked-GI/esophageal issues dominate. Eye symptoms prompt action, per teaching.
Question 2 of 5
The patient is being discharged home with furosemide (Lasix). When providing discharge teaching, which instruction will the nurse include?
Correct Answer: D
Rationale: It is important for the nurse to include instructions for monitoring weight as a part of discharge teaching for a patient receiving furosemide (Lasix) because this medication is a diuretic that helps the body get rid of extra water and salt. Monitoring weight can provide important information about fluid status. A weight gain of more than 1 lb in a day or 2-3 lbs in a week should be reported to the healthcare provider as it may indicate fluid retention or worsening heart failure. This can help prevent complications and ensure appropriate management of the patient's condition.
Question 3 of 5
A 37-year-old man is found to have hypercholesterolemia during a routine checkup. The physician prescribes lovastatin and counsels the patient to make healthy dietary and lifestyle changes to keep his cholesterol under control. Two weeks later, he returns complaining of severe muscle pain, possibly caused by his lovastatin therapy. He insists that he is taking the medication exactly as prescribed, but the physician knows that lovastatin is metabolized by the cytochrome P450 3A4. What else may he be using that would explain his condition?
Correct Answer: B
Rationale: Lovastatin's myopathy (muscle pain) suggests a CYP3A4 interaction. Grapefruit juice inhibits CYP3A4, increasing lovastatin levels, causing toxicity. Barbiturates , Griseofulvin , and Phenytoin induce CYP3A4, reducing levels. St. John's wort (E) also induces. Grapefruit juice fits the timeline and mechanism, explaining the adverse effect.
Question 4 of 5
Fundamental action of drugs that can be used as substitute for what is lacking in the body.
Correct Answer: C
Rationale: The fundamental action of drugs that can be used as a substitute for what is lacking in the body falls under the category of Replacement. In medical terms, replacement therapy is a type of treatment that involves replacing a hormone or other important substance that is deficient or lacking in the body. For example, individuals with hypothyroidism are often prescribed levothyroxine as a replacement therapy to make up for the thyroid hormone deficiency in their body. Similarly, insulin is used to replace the deficient insulin in individuals with diabetes. Therefore, when drugs are administered to compensate for a deficiency or lack of a specific substance in the body, they are categorized under the fundamental action of Replacement.
Question 5 of 5
A 6-year-old boy from Connecticut presents to the emergency department with a bulls-eye-shaped rash on his upper left arm after he went hiking with his family a couple of days ago. He also has had intermittent fevers and muscle aches. The blood test for Lyme disease is positive. He has a history of hearing loss in his left ear from trauma. What side effect would prevent the physician from treating the boy with doxycycline?
Correct Answer: A
Rationale: Lyme disease (bulls-eye rash) in a 6-year-old is treated with doxycycline, but tooth discoloration in children under 8-contraindicates it. Tetracyclines bind calcium, staining developing teeth. Anemia , nephrotoxicity , and ototoxicity are rare. Myalgias (E) aren't relevant. Given his age, amoxicillin is preferred to avoid this permanent cosmetic effect, despite doxycycline's efficacy against Borrelia burgdorferi.
