Correct Answer: C

Rationale: In a client with chronic kidney disease receiving erythropoietin therapy, elevated blood pressure is the most concerning assessment finding. Erythropoietin can increase red blood cell production, leading to thicker blood, which in turn can elevate blood pressure. Elevated blood pressure in this scenario may indicate worsening hypertension, which requires prompt intervention to prevent complications such as stroke, heart attack, or further kidney damage. Increased fatigue (choice A) is a common symptom in CKD patients and can be expected with erythropoietin therapy. Headache (choice B) can occur but is less concerning than elevated blood pressure in this context. Low urine output (choice D) is a significant finding in CKD, but in a client receiving erythropoietin, elevated blood pressure takes precedence due to its potential for immediate adverse effects.

Correct Answer: C

Rationale: Assessing the client's oxygen saturation is the first priority in managing a client with COPD receiving supplemental oxygen to ensure adequate oxygenation. Monitoring oxygen saturation levels helps in determining the effectiveness of the oxygen therapy and if adjustments are needed. Elevating the head of the bed can help with breathing but is not the first priority. Administering oxygen therapy as prescribed is important, but assessing the current oxygen saturation comes before administering more oxygen. Obtaining an arterial blood gas (ABG) sample may provide valuable information, but it is not the initial intervention needed in this situation.

Correct Answer: A

Rationale: The client is exhibiting signs of severe anemia and hypovolemic shock, indicated by low hemoglobin levels and hypotension. The first priority is to address the low hemoglobin by transfusing packed red blood cells to improve oxygen-carrying capacity and perfusion to vital organs. While obtaining blood and sputum cultures is important for identifying potential infections, infusing normal saline can help with volume expansion but does not address the primary issue of severe anemia. Titrating oxygen to maintain an oxygen saturation of 90% is crucial but should follow the administration of packed red blood cells to optimize oxygen delivery.

Correct Answer: C

Rationale: The correct answer is C. The presence of a new murmur in a client with heart failure receiving digoxin and furosemide is concerning as it may indicate valvular problems or other complications that require immediate intervention. A heart rate of 60 beats per minute and an apical pulse of 58 beats per minute are within normal limits for a client with heart failure on these medications. A blood pressure of 100/60 mmHg, while slightly low, may be expected due to the diuretic effect of furosemide and may not require immediate intervention unless the client is symptomatic.

Correct Answer: C

Rationale: The correct answer is C. Fresh fruit salad with low-fat yogurt is a healthier choice for managing the diet of a 12-year-old boy with a high BMI and elevated HBA1C. This choice provides a good balance of nutrients, fiber, and low-fat content, helping to lower BMI and maintain healthy blood sugar levels. Choices A, B, and D are less ideal as they contain higher levels of refined carbohydrates, saturated fats, and sugars, which can contribute to weight gain and worsen blood sugar control in this scenario.
