Nursing Elites

1. A patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What outcome should the nurse expect if the medication is effective?

• A. Decreased urinary frequency and urgency
• B. Increased prostate size
• C. Increased blood pressure
• D. Decreased blood pressure

Correct answer: A

Rationale: The correct answer is A: Decreased urinary frequency and urgency. Finasteride is used to reduce the size of the prostate gland in patients with BPH. As a result, when the medication is effective, the patient should experience a decrease in urinary frequency and urgency. Choices B, C, and D are incorrect. Choice B is inaccurate because finasteride aims to reduce prostate size, not increase it. Choices C and D are unrelated to the action of finasteride in treating BPH.

2. What are the major mechanisms of spinal cord injuries?

• A. Hypoextension, expansion, hyperflexion
• B. Hyperflexion, expansion, hypometabolism
• C. Hypermetabolism, compression, hyperextension
• D. Hyperextension, hyperflexion, compression

Correct answer: D

Rationale: The correct answer is D. Spinal cord injuries commonly occur due to hyperextension, hyperflexion, and compression. Hyperextension and hyperflexion refer to the excessive bending or stretching of the spinal cord, while compression is the exertion of pressure on the spinal cord. These mechanisms can lead to damage such as contusions, lacerations, and compression of the spinal cord. Choices A, B, and C are incorrect as they do not accurately represent the major mechanisms of spinal cord injuries.

3. A patient is taking alendronate (Fosamax) for the treatment of osteoporosis. What instructions should the nurse provide to ensure the effectiveness of the medication?

• A. Take the medication with food to avoid gastrointestinal upset.
• B. Take the medication in the morning with a full glass of water and remain upright for at least 30 minutes.
• C. Take the medication before bed to ensure absorption during sleep.
• D. Take the medication with milk to enhance calcium absorption.

Correct answer: B

Rationale: The correct answer is B. Alendronate should be taken in the morning with a full glass of water and the patient should remain upright for at least 30 minutes. This is important to prevent esophageal irritation and ensure proper absorption of the medication. Choice A is incorrect because alendronate should not be taken with food as it can decrease its absorption. Choice C is incorrect as taking the medication before bed increases the risk of esophageal irritation and reduces absorption due to lying down. Choice D is also incorrect because taking alendronate with milk or other calcium-rich foods can decrease its absorption.

4. A nursing student having trouble moving her head from side to side is likely experiencing a problem with which type of neurons?

• A. General visceral efferent neurons
• B. Preganglionic neurons
• C. Parasympathetic postganglionic neurons
• D. Pharyngeal efferent neurons

Correct answer: D

Rationale: The correct answer is D: Pharyngeal efferent neurons. Pharyngeal efferent neurons are responsible for controlling head movements, including side-to-side motions. General visceral efferent neurons (Choice A) are involved in innervating smooth muscles and glands in the body's internal organs. Preganglionic neurons (Choice B) are part of the autonomic nervous system and connect the central nervous system to the ganglia. Parasympathetic postganglionic neurons (Choice C) are the second neurons in the parasympathetic nervous system pathway, responsible for innervating target organs. In this case, the issue with moving the head from side to side indicates a problem with the pharyngeal efferent neurons.

5. Which of the following is a characteristic of osteosarcoma?

• A. Slow-growing tumor that begins in the bone marrow
• B. Solitary tumor that most often affects the metaphyseal region of the femur or tibia
• C. An aggressive tumor most often found in the bone marrow of long bones
• D. A tumor that infiltrates the trabeculae in spongy bone and implants in surrounding tissue

Correct answer: C

Rationale: Osteosarcoma is an aggressive bone tumor that most commonly arises in the bone marrow of long bones, such as the femur or tibia. Choice A is incorrect as osteosarcoma is not a slow-growing tumor but rather a fast-growing one. Choice B is incorrect as osteosarcoma is not typically solitary but can involve multiple lesions. Choice D is incorrect as osteosarcoma primarily affects the medullary (marrow) cavity of bones, rather than infiltrating the trabeculae in spongy bone and surrounding tissue.
