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. A client was involved in a motor vehicle accident in which the seat belt was not worn. The client is exhibiting crepitus, decreased breath sounds on the left, complains of shortness of breath, and has a respiratory rate of 34/min. Which of the following assessment findings should concern the nurse the most?

• A. temperature of 102�F and a productive cough
• B. arterial blood gases (ABGs) with a PaO2 of 92 mmHg and PaCO2 of 40 mmHg
• C. trachea deviating to the right
• D. barrel-chested appearance

Correct answer: C

Rationale: The correct answer is 'trachea deviating to the right.' A mediastinal shift is indicative of a tension pneumothorax, which is a dangerous complication seen in trauma patients with symptoms like crepitus, decreased breath sounds, shortness of breath, and tachypnea. Assessing for acute traumatic injuries is crucial in this context. Choice A, a temperature of 102�F and a productive cough, is common in pneumonia cases and not as concerning as a mediastinal shift. Choice B, ABGs with a PaO2 of 92 mmHg and PaCO2 of 40 mmHg, shows values within normal limits and does not suggest a tension pneumothorax. Choice D, a barrel-chested appearance, is typical of COPD and not directly related to the acute traumatic injury described. A tension pneumothorax is a medical emergency where air cannot escape the pleural cavity, leading to lung collapse and a mediastinal shift to the unaffected side with a downward displacement of the diaphragm.

3. The test used to differentiate sickle cell trait from sickle cell disease is:

• A. Sickle cell preparation.
• B. Peripheral smear.
• C. Sickledex.
• D. Hemoglobin electrophoresis

Correct answer: D

Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.

4. A client had a Caesarean delivery and is postpartum day 1. She asks for pain medication when the nurse enters the room to do her shift assessment. The client states that her pain level is an 8 on a scale of 1 to 10. What should be the nurse's priority of care?

• A. Give the pain medication and return in an hour for further assessment to allow time for the medication to work.
• B. Complete the postpartum assessment and then give the client pain medication.
• C. Give the pain medication first, do a quick assessment while administering the medication to ensure the pain is not caused by a complication, and return for the full assessment after the client's pain has subsided.
• D. Instruct the patient to do relaxation exercises to relieve her discomfort.

Correct answer: C

Rationale: Pain management is a priority, so the nurse should immediately provide pain medication. However, the nurse should conduct a quick assessment while administering the medication to ensure that a complication, such as hemorrhage, hasn't caused the increased pain. A complete assessment can wait until the pain subsides. Controlling pain will enable the client to move, eliminating other potential complications of delivery and facilitating bonding with the infant. Relaxation techniques can act as an adjunct therapy but by themselves are not usually effective for pain management during the early post-Caesarean period.

5. What type of cells create exocrine secretions?

• A. alpha cells
• B. beta cells
• C. acinar cells
• D. plasma cells

Correct answer: C

Rationale: Acinar cells are responsible for creating exocrine secretions, such as enzymes and digestive juices. Alpha cells are found in the pancreas and are responsible for producing glucagon, beta cells produce insulin, and plasma cells are a type of white blood cell involved in immune responses. Therefore, the correct answer is acinar cells, as they specifically produce exocrine secretions.
