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: iron, folic acid, and B12.
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. The healthcare professional seeks to assess the renal function of an elderly client who is about to receive a nephrotoxic medication. Which of the following labs provides the best indicator for renal function?
- A. urinalysis
- B. creatinine and blood urea nitrogen
- C. chemistry of electrolytes
- D. creatinine clearance
Correct answer: creatinine clearance
Rationale: In the context of an elderly client, assessing renal function before administering a nephrotoxic medication is crucial. While urinalysis and blood urea nitrogen provide valuable information on hydration status and overall health clues, they are not specific indicators of renal function. The chemistry of electrolytes may show abnormalities in renal failure, but it does not directly measure the kidneys' ability to eliminate waste. Creatinine clearance, on the other hand, is considered the best indicator for renal function in the elderly. This test accounts for decreases in lean body mass that can affect blood creatinine levels and is widely used to estimate the glomerular filtration rate, reflecting the kidneys' filtration capability. Therefore, creatinine clearance is the most appropriate lab test to assess renal function in this scenario.
3. The LPN is taking care of a client who is on Phenelzine (Nardil) for depression. Which meal would the nurse encourage the client to avoid?
- A. steak and potatoes
- B. prosciutto and cheese plate
- C. orange juice and toast
- D. carbonated water, shrimp and rice
Correct answer: prosciutto and cheese plate
Rationale: The correct answer is 'prosciutto and cheese plate.' Phenelzine (Nardil) is an MAOI (Monoamine Oxidase Inhibitor), and clients on these drugs should avoid foods high in tyramine due to the risk of dangerous elevations in blood pressure. Prosciutto and aged cheeses are examples of foods rich in tyramine, so they should be avoided. Choices A, C, and D do not contain high levels of tyramine and are considered safe to consume while on Phenelzine.
4. In an emergency situation, the nurse determines whether a client has an airway obstruction. Which of the following does the nurse assess?
- A. ability to speak
- B. ability to hear
- C. oxygen saturation
- D. adventitious breath sounds
Correct answer: ability to speak
Rationale: In an emergency situation to assess for airway obstruction, the nurse should prioritize assessing the client's ability to speak. If a client can speak, it indicates that the airway is patent and not completely obstructed, allowing air to pass through the vocal cords for speech production. Choices B, C, and D are not the primary assessments for determining airway obstruction. Assessing the ability to hear is not directly related to an airway obstruction. While oxygen saturation and adventitious breath sounds are important in respiratory assessments, they are not the initial indicators of an airway obstruction. Oxygen saturation reflects the amount of oxygen in the blood, and adventitious breath sounds refer to abnormal lung sounds that may indicate conditions like pneumonia or bronchitis, but they do not specifically confirm airway patency.
5. Following an automobile accident that caused a head injury to an adult client, the nurse observes that the client sleeps for long periods of time. The nurse determines that the client has experienced injury to the:
- A. hypothalamus.
- B. thalamus.
- C. cortex.
- D. medulla.
Correct answer: hypothalamus.
Rationale: The hypothalamus is responsible for regulating sleep patterns among other functions. Injury to the hypothalamus can disrupt the sleep-wake cycle, leading to excessive sleepiness or changes in sleep patterns. Choices B, C, and D are incorrect as they do not primarily control sleep regulation. The thalamus is involved in relaying sensory information, the cortex is responsible for higher brain functions, and the medulla controls vital functions such as heartbeat and breathing.
