Nursing Elites

1. After ingestion of cysts, how long does it take for the symptoms of giardiasis to develop?

• A. 12 to 24 hours
• B. 3 to 5 days
• C. 1 to 2 weeks
• D. 2 to 3 months

Correct answer: B

Rationale: Giardiasis symptoms typically develop 3 to 5 days after ingestion of the cysts. This timeframe aligns with the incubation period of the Giardia parasite. Choice A (12 to 24 hours) is too short for giardiasis to manifest. Choice C (1 to 2 weeks) and choice D (2 to 3 months) represent durations that are not consistent with the usual onset of symptoms in giardiasis.

2. What specific instructions should the nurse provide for a patient starting on alendronate (Fosamax) for osteoporosis to ensure proper administration?

• A. Take the medication with a full glass of water and remain upright for at least 30 minutes.
• B. Take the medication with milk to enhance calcium absorption.
• C. Take the medication at bedtime to ensure absorption during sleep.
• D. Take the medication with food to prevent nausea.

Correct answer: A

Rationale: The correct answer is A. Alendronate should be taken with a full glass of water, and patients should remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption. Choice B is incorrect because alendronate should not be taken with milk, as it can interfere with its absorption. Choice C is incorrect as there is no specific instruction to take alendronate at bedtime. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food, to enhance absorption.

3. A patient with a history of breast cancer is prescribed tamoxifen (Nolvadex). What critical information should the nurse include in the patient education?

• A. Tamoxifen may increase the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots.
• B. Tamoxifen may cause weight gain, so patients should monitor their diet.
• C. Tamoxifen may decrease the risk of osteoporosis, so patients should ensure adequate calcium intake.
• D. Tamoxifen may cause hot flashes and other menopausal symptoms.

Correct answer: A

Rationale: Tamoxifen increases the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots and the importance of seeking immediate medical attention if they occur.

4. A 30-year-old female has suffered a third-degree burn to her hand after spilling hot oil in a kitchen accident. Which teaching point by a member of her care team is most appropriate?

• A. Your hand will likely heal without the need for a skin graft.
• B. You might experience a loss of sensation in your hand after it heals.
• C. Be sure to keep your hand elevated to reduce swelling.
• D. We will need to monitor you for infection as your hand heals.

Correct answer: D

Rationale: In third-degree burns, infection is a major concern due to the extensive damage to the skin. Monitoring for infection is crucial. Choice A is incorrect because third-degree burns often require skin grafts due to the severity of the injury. Choice B is incorrect as loss of sensation is more common in nerve damage and not necessarily in burns. Choice C is incorrect because while elevation can help with swelling in minor burns, it is not the most critical concern in third-degree burns.

5. Which of the following is NOT an example of clinical manifestations of leukemia and lymphoma?

• A. Fatigue
• B. Increased risk of bleeding
• C. Increased risk of infections
• D. Increased energy and strength

Correct answer: D

Rationale: The correct answer is D: Increased energy and strength. Leukemia and lymphoma typically present with symptoms such as fatigue, weakness, increased risk of bleeding, and increased risk of infections. Patients with these conditions often experience a lack of energy and strength due to the disease's impact on the body. Therefore, increased energy and strength are not typical manifestations of leukemia and lymphoma.
