Correct Answer: D

Rationale: In this scenario, the patient's presentation with periorbital bruising and bloody ear drainage suggests a basilar skull fracture. Projectile vomiting, as described in choice D, is concerning for increased intracranial pressure due to the skull fracture. This finding warrants immediate intervention to prevent further neurological compromise. Choices A, B, and C are not the priority in this situation. Rebound abdominal tenderness (choice A) is indicative of intra-abdominal injury but is not as urgent as managing potential intracranial issues. Diminished breath sounds (choice B) and rib pain with deep inspiration (choice C) may suggest underlying chest injuries, which need attention but are not as immediately life-threatening as increased intracranial pressure.

Correct Answer: C

Rationale: When a pediatric client is taking propranolol, the nurse should instruct the parents to report signs of overdose, including bradycardia. Propranolol is a beta-blocker that can lead to dangerously slow heart rate as a sign of overdose. While increased respiratory rate, seizures, and irritability may occur in some cases, bradycardia is the most critical symptom indicating an overdose of this medication.

Correct Answer: B

Rationale: The correct first action for a client with COPD experiencing increased shortness of breath and fatigue is to check the client's oxygen saturation. This assessment helps the nurse evaluate the client's respiratory status promptly. Administering a bronchodilator (Choice A) may be necessary but should come after assessing the oxygen saturation. Repositioning the client to a high Fowler's position (Choice C) can help improve breathing but should not precede oxygen saturation assessment. Administering oxygen via nasal cannula (Choice D) may be needed based on the oxygen saturation results, but assessing it first is crucial.

Correct Answer: A

Rationale: The correct answer is to administer a nebulizer treatment of albuterol. In acute bronchospasm, the priority intervention is to deliver a bronchodilator like albuterol to open the airways and improve breathing. Starting an IV infusion of normal saline (Choice B) may be necessary but not the priority in this situation. Administering oxygen at 4L/min via nasal cannula (Choice C) is important but not the first intervention for bronchospasm. Positioning the client in a high Fowler's position (Choice D) can help with breathing but is not the priority over administering a bronchodilator.

Correct Answer: B

Rationale: Monitoring daily weight and blood pressure is crucial to assess the effectiveness of diuretics (furosemide) and antihypertensives (atenolol, enalapril) in managing heart failure and hypertension. Changes in weight indicate fluid status, while blood pressure readings reflect the control of hypertension. Assessing bowel sounds and range of motion are important but not directly related to evaluating the effectiveness of these specific medications in this scenario. Monitoring for hypokalemia is important due to furosemide's potential side effect, but it is not the primary assessment to evaluate medication effectiveness.
