Correct Answer: A

Rationale: The correct answer is to administer bronchodilators as prescribed. During an acute asthma attack, the priority is to open the airways quickly to help the client breathe more easily. Oxygen may be needed but bronchodilators take precedence as they directly target bronchoconstriction. Chest physiotherapy is not indicated in the acute phase of asthma and may exacerbate the condition. While emotional support is important, addressing the airway obstruction takes precedence in this situation.

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 teaching for a client prescribed metformin includes monitoring renal function regularly due to the risk of lactic acidosis, especially in clients with impaired kidney function. While taking metformin with meals can reduce gastrointestinal upset, it is not the highest priority teaching point. Avoiding alcohol is generally recommended but not the most critical teaching point in this scenario. Checking blood glucose levels regularly is important for diabetes management but not specifically related to metformin use.

Correct Answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.

Correct Answer: B

Rationale: The correct answer is B. Monitoring the client's compliance with NPO status is the priority assessment. Ensuring the client remains NPO (nothing by mouth) is crucial to reduce the risk of aspiration during surgery. Assessing the client's understanding of the procedure is important but not the priority at this moment. Checking vital signs is also essential but ensuring NPO status takes precedence for patient safety. Ensuring the client's consent form is signed is necessary but not the priority assessment compared to maintaining NPO status.
