1. A person who had a left CVA and right lower extremity hemiparesis is being instructed by a nurse to use a quad cane. Which of the following is the most appropriate gait sequence?
- A. Place the cane in the patient's left upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
- B. Place the cane in the patient's left upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
- C. Place the cane in the patient's right upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
- D. Place the cane in the patient's right upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
Correct answer: A
Rationale: The correct gait sequence for a person with left CVA and right lower extremity hemiparesis using a quad cane is to place the cane in the patient's strong upper extremity, which is the left upper extremity in this case. The correct sequence should be right lower extremity followed by left upper extremity, as this pattern mimics a normal gait pattern. Therefore, Choice A is the correct answer. Choices B, C, and D are incorrect because they do not follow the proper gait sequence for this specific patient's condition. The cane should be placed in the strong upper extremity, and the affected lower extremity should move first to provide stability and support, which is essential in this situation.
2. A client arrives in the emergency department after severely lacerating the left hand with a knife. HR 96, BP 150/88, R36. The client is extremely anxious and crying uncontrollably. Based on this assessment, the nurse anticipates that this client would be in which acid-base imbalance?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: B
Rationale: The correct answer is respiratory alkalosis. Hyperventilation due to anxiety, pain, shock, severe infection, fever, or liver failure can lead to respiratory alkalosis. In this scenario, the client is extremely anxious and crying uncontrollably, indicating an increased respiratory rate and CO2 loss. Respiratory acidosis (choice A) is incorrect as it is characterized by an increase in CO2 levels, not a loss. Metabolic acidosis (choice C) involves a decrease in blood pH due to an accumulation of acids or loss of bicarbonate, which is not the case here. Metabolic alkalosis (choice D) results from excess bicarbonate or a loss of acids, not from increased CO2 loss due to hyperventilation.
3. A 15-year-old high school wrestler has been taking diuretics to lose weight to compete in a lower weight class. Which of the following medical tests is most likely to be given?
- A. Lab values of Potassium and Sodium
- B. Lab values of Glucose and Hemoglobin
- C. ECG
- D. CT scan
Correct answer: A
Rationale: Diuretics can disrupt the sodium and potassium balance, potentially leading to cardiac complications. Monitoring the lab values of potassium and sodium is crucial to assess electrolyte imbalances due to diuretic use. Testing glucose and hemoglobin levels is not directly related to diuretic use in this context. An ECG would be indicated if there were signs or symptoms of cardiac abnormalities, but it is not the primary test to monitor the effects of diuretics. A CT scan is not typically used to assess electrolyte imbalances caused by diuretics.
4. 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.
5. Which of the following goals is the most important for the nurse to address for a client admitted to the cardiac rehabilitation unit?
- A. Reduction of anxiety
- B. Referral to community resources
- C. Identification of lifestyle changes
- D. Verbalization of energy-conservation techniques
Correct answer: C
Rationale: The most important goal for a client admitted to the cardiac rehabilitation unit is the identification of lifestyle changes. This is crucial in promoting cardiovascular health and preventing future cardiac issues. Lifestyle changes such as diet modifications, exercise routines, smoking cessation, and stress management play a significant role in improving the overall cardiovascular well-being of the patient. While reducing anxiety, referring to community resources, and verbalizing energy-conservation techniques are all important aspects of care, identifying lifestyle changes is the primary focus in helping the client achieve long-term cardiovascular wellness.
