1. Erythropoietin used to treat anemia in clients with renal failure should be given in conjunction with:

• A. iron, folic acid, and B12.
• B. an increase in protein in the diet.
• C. vitamins A and C.
• D. an increase in calcium in the diet.

Correct answer: A

Rationale: Erythropoietin is necessary for red blood cell (RBC) production, and in clients with renal failure who lack endogenous erythropoietin, exogenous erythropoietin is administered. However, for erythropoietin to effectively stimulate RBC production, adequate levels of iron, folic acid, and vitamin B12 are crucial. These nutrients are essential for RBC synthesis and maturation. Therefore, the correct answer is to give iron, folic acid, and B12 with erythropoietin. Choice B, an increase in protein in the diet, is not necessary for RBC production and may exacerbate uremia in clients with renal failure. Choices C and D, vitamins A and C, and an increase in calcium in the diet, respectively, are not directly related to RBC production and are not required to enhance the effectiveness of erythropoietin.

2. In Parkinson's disease, a client's difficulty in performing voluntary movements is known as:

• A. Akinesia.
• B. Dyskinesia.
• C. Chorea.
• D. Dystonia.

Correct answer: C.

Rationale: In Parkinson's disease, the client's difficulty in performing voluntary movements is termed dyskinesia. Dyskinesia refers to the impairment of the ability to execute voluntary muscle movements. Akinesia, on the other hand, refers to the absence or lack of voluntary movement. Chorea is characterized by involuntary, rapid, irregular movements. Dystonia involves sustained muscle contractions resulting in abnormal postures or twisting movements. Therefore, dyskinesia is the specific term used for the described difficulty in Parkinson's disease.

3. An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?

• A. It protects the bacteria from antibiotic and immunologic destruction.
• B. Glycocalyx neutralizes the antibiotic, rendering it ineffective.
• C. It competes with the antibiotic for binding sites on the microbe.
• D. Glycocalyx provides nutrients for microbial growth.

Correct answer: A

Rationale: Bacterial glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes. It plays a significant role in protecting bacteria by enhancing adherence to surfaces, resisting phagocytic engulfment by white blood cells, and preventing antibiotics from contacting the microbe. Choice A is correct because glycocalyx shields the bacteria from both antibiotics and the immune system, allowing the infection to persist. Choices B, C, and D are incorrect because glycocalyx does not neutralize antibiotics, compete for binding sites with antibiotics, or provide nutrients for microbial growth.

4. The nurse observes a nursing assistant performing AM care for a client with a new leg cast. Which action by the assistant will the nurse intervene?

• A. Lifting the affected leg with the palms of the hand
• B. Covering the affected leg with a blanket to avoid chills
• C. Placing plastic over the groin prior to bathing
• D. Elevating the cased leg on two pillows

Correct answer: B

Rationale: The correct answer is covering the affected leg with a blanket to avoid chills. Covering the leg with a blanket can prevent the evaporation of heat from the new cast, which can lead to skin irritation or discomfort. Lifting the affected leg with the palms of the hand is appropriate as it helps in providing support and prevents unnecessary pressure on the cast. Placing plastic over the groin prior to bathing is also acceptable to protect the area from getting wet. Elevating the cased leg on two pillows helps reduce swelling and promotes circulation, making it a suitable action.

5. A nurse is caring for a patient in the step-down unit. The patient has signs of increased intracranial pressure. Which of the following is not a sign of increased intracranial pressure?

• A. Bradycardia
• B. Increased pupil size bilaterally
• C. Change in LOC
• D. Vomiting

Correct answer: B

Rationale: The correct answer is 'Increased pupil size bilaterally.' When assessing for signs of increased intracranial pressure, bilateral pupil dilation is not typically associated with this condition. Instead, unilateral pupil changes, especially one pupil becoming dilated or non-reactive while the other remains normal, are indicative of increased ICP. Bradycardia, a change in level of consciousness (LOC), and vomiting are commonly seen in patients with increased intracranial pressure due to the brain's response to the rising pressure. Therefore, the presence of bilateral pupil dilation goes against the typical pattern observed in patients with increased intracranial pressure.
