Correct Answer: A

Rationale: The correct answer is A: Blood urea nitrogen (BUN). In CKD, the kidneys are unable to effectively filter waste products, leading to an increase in BUN levels. Elevated BUN indicates impaired kidney function. Calcium, potassium, and sodium levels may also be affected in CKD, but they are more likely to be imbalanced rather than consistently elevated. Calcium levels may be low due to impaired vitamin D activation, potassium levels may be high due to decreased excretion, and sodium levels can fluctuate based on fluid status. Therefore, while these lab values may be abnormal in CKD, BUN is the most consistently elevated marker of kidney dysfunction.

Correct Answer: B

Rationale: The correct answer is B: strain. A strain refers to excessive stretching or tearing of a muscle or tendon, not a ligament. A sprain (choice A) is the correct term for excessive stretching of a ligament. Subluxation (choice C) refers to partial dislocation of a joint, not a ligament injury. Distortion (choice D) is a general term that does not specifically describe ligament stretching. Therefore, the correct term for excessive stretching of a ligament is a sprain, making choice A the correct answer.

Correct Answer: A

Rationale: Step-by-step rationale for choosing Albuterol as the correct answer: 1. Albuterol is a rapid-acting bronchodilator that provides immediate relief by relaxing the airway muscles during asthma exacerbation. 2. It is the first-line medication recommended by guidelines for acute asthma attacks due to its quick onset of action. 3. Albuterol helps in opening the airways, improving airflow, and relieving symptoms like shortness of breath and wheezing. 4. Epinephrine is not the first choice for asthma exacerbation as it can have more systemic side effects. 5. Levalbuterol is a similar medication to Albuterol but may not be as widely available or cost-effective. 6. IV corticosteroids are important for long-term control but take longer to show effects, making them less suitable as the initial treatment for acute exacerbation.

Correct Answer: A

Rationale: The correct answer is A: Administering bronchodilators as prescribed. Rationale: 1. Bronchodilators help dilate the airways, improving airflow in COPD patients. 2. Priority is to address the underlying respiratory issue. 3. Bronchodilators are a standard treatment for managing COPD symptoms. 4. Improving airway patency is crucial in COPD exacerbations. Summary: - B: Encouraging avoidance of physical activity is incorrect as it can lead to deconditioning. - C: Providing supplemental oxygen is important but not the priority in this case. - D: Monitoring for acute kidney injury is unrelated to COPD management.

Correct Answer: A

Rationale: The correct first action is A: Apply pressure and elevate the limb. This is because applying pressure helps control bleeding and elevating the limb reduces blood flow to the area, minimizing further blood loss. This immediate intervention is crucial in managing the traumatic amputation and preventing complications. Summary of why other choices are incorrect: B: Stopping bleeding and controlling shock can be important but not the first action. C: Placing the client in a Trendelenburg position (feet elevated higher than the head) is contraindicated in cases of traumatic amputation as it can increase bleeding. D: Placing the client in a sitting position is not appropriate as it can worsen bleeding and lead to further complications.
