A male patient with benign prostatic hyperplasia (BPH) is being treated with tamsulosin (Flomax). What should the nurse include in the teaching plan for this patient?
- A. Avoid lying down after taking the medication.
- B. Take the medication with meals.
- C. Report any side effects such as dizziness or fainting.
- D. Take the medication at bedtime.
Correct Answer: C
Rationale: The correct answer is C: 'Report any side effects such as dizziness or fainting.' Patients taking tamsulosin should be advised to report any side effects, such as dizziness or fainting, which can occur due to orthostatic hypotension. Choices A, B, and D are incorrect because avoiding lying down after taking the medication, taking it with meals, or at bedtime are not specific teaching points related to the potential side effects of tamsulosin.

A patient with breast cancer is prescribed tamoxifen (Nolvadex). What should the nurse emphasize during patient education?
- A. Tamoxifen may increase the risk of venous thromboembolism, so patients should be aware of the signs and symptoms of blood clots.
- B. Tamoxifen may cause weight gain, so patients should monitor their diet.
- C. Tamoxifen may cause hot flashes and other menopausal symptoms.
- D. Tamoxifen may decrease the risk of osteoporosis, so patients should ensure adequate calcium intake.
Correct Answer: A
Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism, a serious side effect. Therefore, patients should be educated about the signs and symptoms of blood clots, such as swelling, pain, and redness in the legs, and advised to seek immediate medical attention if they occur. Choice B is incorrect because weight gain is not a significant side effect of tamoxifen. Choice C is incorrect because hot flashes and menopausal symptoms are common side effects of tamoxifen but are not as critical to address as venous thromboembolism. Choice D is incorrect because tamoxifen does not decrease the risk of osteoporosis; in fact, it may increase the risk of bone loss in premenopausal women.
When educating a patient starting on oral contraceptives, what should the nurse include regarding the medication's effectiveness?
- A. Oral contraceptives are 100% effective when taken correctly.
- B. Oral contraceptives are effective immediately after starting.
- C. Oral contraceptives are less effective if taken with antibiotics.
- D. Oral contraceptives are less effective if taken with food.
Correct Answer: C
Rationale: The correct answer is C. Oral contraceptives can be less effective when taken with certain antibiotics as they may interfere with the contraceptive's efficacy, potentially leading to decreased effectiveness. Therefore, patients should be advised to use additional contraception methods if they are also taking antibiotics. Choice A is incorrect because while oral contraceptives are highly effective, they are not 100% foolproof. Choice B is incorrect as oral contraceptives may take some time to reach their full effectiveness after starting. Choice D is incorrect since taking oral contraceptives with food does not necessarily impact their effectiveness.
A patient who is being administered isoniazid (INH) for tuberculosis has a yellow color in the sclera of her eye. What other finding would lead you to believe that hepatotoxicity has developed?
- A. Diarrhea
- B. Numbness
- C. Diminished vision
- D. Light-colored stools
Correct Answer: A
Rationale: The correct answer is A: Diarrhea. Hepatotoxicity caused by isoniazid can present with various symptoms, including yellow discoloration of the sclera of the eyes, which indicates jaundice. Another common sign of hepatotoxicity is gastrointestinal symptoms such as nausea, vomiting, and diarrhea, which can occur due to liver dysfunction affecting bile production and digestion. Numbness (choice B) is more commonly associated with peripheral neuropathy caused by isoniazid, while diminished vision (choice C) and light-colored stools (choice D) are not typical manifestations of hepatotoxicity.
What instruction should the nurse include in this patient's health education regarding chloroquine phosphate (Aralen) for malaria prophylaxis?
- A. "Take your pill on the same day each week."
- B. "Watch out for any unusual rash on your trunk and arms, but this isn't cause for concern."
- C. "Remember to take your chloroquine on an empty stomach."
- D. "We'll provide you with enough syringes and teach you how to inject the drug."
Correct Answer: A
Rationale: The correct instruction for the nurse to include in this patient's health education regarding chloroquine phosphate (Aralen) for malaria prophylaxis is to "Take your pill on the same day each week." This is essential because chloroquine is typically taken once a week on the same day to ensure consistent protection against malaria. Choice B is incorrect because while rashes are a possible side effect of chloroquine, they are not a usual occurrence and should be reported to the healthcare provider. Choice C is incorrect because chloroquine does not need to be taken on an empty stomach. Choice D is incorrect as chloroquine is typically administered orally, not by injection.
When preparing to administer parenteral acyclovir (Zovirax) to an 80-year-old patient with chronic renal failure and herpes simplex, what would the nurse expect in regard to the dose?
- A. The dose is smaller due to the herpes simplex infection.
- B. The dose is smaller based on the patient's kidney function.
- C. The dose is higher in treating genital herpes.
- D. The dose is higher if the creatinine clearance is above 4.0 mg/dL.
Correct Answer: B
Rationale: In patients with chronic renal failure, especially in older adults, dosages of medications excreted renally need to be adjusted based on kidney function. Acyclovir is primarily eliminated by the kidneys, so in a patient with chronic renal failure, the dose would need to be smaller to prevent drug accumulation and toxicity. Choice A is incorrect because the dose adjustment is more related to the patient's kidney function than the presence of herpes simplex. Choice C is incorrect because the type of herpes infection does not determine the dose adjustment for acyclovir. Choice D is incorrect as the creatinine clearance is a more accurate measure of kidney function compared to creatinine levels.
