While caring for a client receiving positive-pressure mechanical ventilation, which intervention should the nurse NOT implement to prevent complications?

Correct Answer: D

Rationale: The correct answer is D. Repositioning the endotracheal tube to the opposite side of the mouth daily is not necessary and could potentially lead to complications such as accidental extubation or damage to the airway. A: Elevating the head of the bed helps prevent aspiration. B: Verifying ventilator settings daily ensures proper functioning. C: Administering pantoprazole helps prevent stress ulcers. In summary, D is incorrect because it is unnecessary and poses risks, while A, B, and C are important interventions to prevent complications associated with positive-pressure mechanical ventilation.

Correct Answer: D

Rationale: The correct answer is D: Development of subcutaneous emphysema. This finding indicates air leakage, which can lead to potential complications like tension pneumothorax. Subcutaneous emphysema is a serious concern that requires immediate intervention. A: Chest tube eyelets not visible - This is not a concerning finding as long as the chest tube is properly secured and functioning. B: Continuous bubbling in the suction control chamber - This can indicate proper functioning of the system. C: Presence of tidal fluctuation in the water seal chamber - This indicates that the system is working correctly, with the water seal chamber fluctuating with the patient's breathing.

Correct Answer: A

Rationale: To determine the mL per dose of albuterol syrup, we need to calculate how many mL contain 1.6 mg of albuterol. Given that 2 mg of albuterol is in 5 mL of syrup, we can set up a proportion: 2 mg / 5 mL = 1.6 mg / x mL Cross-multiply to solve for x: 2 * x = 1.6 * 5 2x = 8 x = 4 mL Therefore, the correct answer is A: 4 mL. Choice B (6 mL) is incorrect because it does not match the calculated value. Choice C (10 mL) is incorrect as it is too high based on the calculation. Choice D (5.5 mL) is incorrect as it does not match the precise calculated value of 4 mL.

Correct Answer: D

Rationale: The correct answer is D, Penicillin G. Anthrax is caused by Bacillus anthracis, which is susceptible to ciprofloxacin and doxycycline. Penicillin and amoxicillin are not recommended due to the potential for B. anthracis to produce beta-lactamase, which can make the bacteria resistant to penicillin-based medications. Penicillin G is not effective in treating anthrax and should not be expected as a common treatment option.

Correct Answer: D

Rationale: The correct answer is D: Albuterol via a jet nebulizer. Albuterol is a short-acting beta agonist that works by relaxing the muscles in the airways, helping to open them up and improve airflow. When administered via a nebulizer, it provides quick relief during an acute asthma exacerbation by directly targeting the airways. Cromolyn (A) is a mast cell stabilizer that is used for preventing asthma symptoms, not for acute exacerbations. Montelukast (B) is a leukotriene receptor antagonist that is used for maintenance therapy, not for immediate relief. Budesonide (C) is an inhaled corticosteroid used for long-term control of asthma, not for acute symptom relief.
