1. Which of the following syndromes associated with incomplete lesions of the spinal cord results from damage to one-half of the spinal cord?

• A. Brown-S�quard syndrome
• B. posterior cord syndrome
• C. central cord syndrome
• D. cauda equina syndrome

Correct answer: A

Rationale: Brown-S�quard syndrome is indeed associated with incomplete lesions of the spinal cord, and it specifically results from damage to one-half of the spinal cord. This syndrome manifests as ipsilateral motor paralysis, ipsilateral loss of vibration and proprioception, and contralateral loss of pain and temperature sensation. Posterior cord syndrome mainly involves the loss of proprioception and vibratory sense, while sparing motor function and pain sensation. Central cord syndrome typically presents with more weakness in the upper extremities compared to the lower extremities due to central spinal cord damage. Cauda equina syndrome affects the nerve roots at the level of the conus medullaris, leading to symptoms like lower extremity weakness, numbness, and bowel/bladder dysfunction.

2. Which of the following is not a function of parathyroid hormone?

• A. moving calcium from bones to the bloodstream
• B. inhibiting renal tubular reabsorption of phosphorus
• C. promoting renal tubular reabsorption of calcium
• D. enhancing renal production of vitamin D metabolites

Correct answer: B

Rationale: The correct answer is 'inhibiting renal tubular reabsorption of phosphorus.' Parathyroid hormone actually inhibits renal tubular reabsorption of phosphorus, making this choice the opposite of its function. Parathyroid hormone functions to move calcium from bones to the bloodstream (Choice A), promote renal tubular reabsorption of calcium (Choice C), and enhance renal production of vitamin D metabolites (Choice D). Therefore, all other choices are functions of parathyroid hormone except for the inhibition of phosphorus reabsorption.

3. Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

• A. skin
• B. adipose tissue
• C. skeletal muscle
• D. myocardium

Correct answer: D

Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.

4. A client with a left arm fracture complains of severe diffuse pain that is unrelieved by pain medication. On further assessment, the nurse notes that the client experiences increased pain during passive motion compared with active motion of the left arm. Based on these assessment findings, which action should the nurse take first?

• A. Contacting the health care provider
• B. Checking if it is time for more pain medication
• C. Encouraging the client to continue active range of motion exercises of the left arm
• D. Repositioning the client for comfort

Correct answer: A

Rationale: The correct answer is to contact the health care provider. The client with early acute compartment syndrome typically complains of severe diffuse pain that is unrelieved by pain medication. Additionally, the affected client experiences greater pain during passive motion compared to active motion. In this situation, it is crucial to notify the health care provider immediately for further evaluation and intervention. Contacting the health care provider is essential to ensure timely diagnosis and appropriate management of the condition. Checking for more pain medication, encouraging active range of motion exercises, or repositioning the client may not address the underlying issue of acute compartment syndrome and could delay necessary interventions. Therefore, the priority action should be to involve the healthcare provider for prompt assessment and treatment.

5. A nurse discovers that another nurse has administered an enema to a client even though the client told the nurse that he did not want one. Which is the most appropriate action for the nurse to take?

• A. Report the incident to the nursing supervisor
• B. Confront the nurse who gave the enema and inform the nurse that she may face charges of battery
• C. Tell the client that the nurse did the right thing in giving the enema
• D. Contact the client's health care provider

Correct answer: A

Rationale: Battery is any intentional touching of a client without the client's consent, which violates the client's rights. If a nurse discovers such an incident, they should report it to the nursing supervisor. Confronting the nurse and threatening charges of battery could lead to unnecessary conflict. Telling the client that the nurse did the right thing is incorrect as it goes against the client's wishes. While the health care provider may need to be notified eventually, the first step should be reporting the incident to the nursing supervisor to address the violation appropriately.
