Correct Answer: C

Rationale: When a client is vomiting, the priority action for the nurse is to prevent the client from aspirating. Aspiration can lead to serious respiratory complications. Providing the client with an emesis basin can be helpful but preventing aspiration takes precedence. Notifying housekeeping and administering an antiemetic are secondary actions that can be addressed once the client's safety is ensured.

Correct Answer: D

Rationale: Penicillin G is NOT commonly used to treat anthrax. Anthrax is typically treated with antibiotics such as ciprofloxacin and doxycycline due to penicillin's limited efficacy against anthrax bacteria. Amoxicillin is also not a preferred choice for anthrax treatment. Therefore, penicillin G would not be expected as a primary medication for anthrax treatment following bioterrorism exposure.

Correct Answer: C

Rationale: Following a total hip arthroplasty, the client should be instructed to restrict hip flexion past 90 degrees to prevent dislocation of the prosthesis. Restricting flexion past 120 degrees is excessive and could lead to complications. Therefore, the nurse should verify this prescription with the provider to ensure the client's safety and proper postoperative care.

Correct Answer: D

Rationale: During an acute asthma exacerbation, the preferred medication for symptom relief is a short-acting beta-agonist like albuterol, typically delivered via a jet nebulizer for quick onset and efficacy. Cromolyn, montelukast, and budesonide are not as effective for immediate symptom relief in acute exacerbations and are more commonly used for prevention or long-term management of asthma symptoms.

Correct Answer: B

Rationale: In cases of snake bites, it is essential to immobilize the affected extremity with a splint to prevent the spread of venom throughout the body. Raising the extremity above the heart level can promote venom spread, and applying ice or a tourniquet can worsen the condition. Immobilization helps reduce movement and slows the circulation of venom, aiding in the prevention of further complications.
