Correct Answer: A

Rationale: The correct answer is to administer bronchodilators. In an acute asthma attack, the priority is to open the airways and improve airflow. Bronchodilators like albuterol are crucial in providing immediate relief to the patient. Monitoring oxygen saturation (choice B) is important but administering bronchodilators takes precedence in managing the acute attack. Providing supplemental oxygen (choice C) may be necessary but addressing the airway obstruction with bronchodilators is the priority. Starting IV fluids (choice D) is not the priority in an acute asthma attack unless specifically indicated for other reasons such as dehydration.

Correct Answer: C

Rationale: When administering enoxaparin for the prevention of DVT, the nurse should inject the medication into the lateral abdominal wall. This site is preferred for subcutaneous injections of enoxaparin to reduce the risk of bleeding or injury. Expelling air bubbles, massaging the injection site, or administering an NSAID for discomfort are not appropriate actions and could lead to complications or ineffective medication delivery.

Correct Answer: C

Rationale: The correct intervention for a client with deep vein thrombosis (DVT) is to apply cold packs to the affected extremity. Cold packs help reduce swelling and pain by causing vasoconstriction. Massaging the affected extremity could dislodge a clot, leading to serious complications. Encouraging bed rest may increase the risk of clot propagation, while frequent ambulation is contraindicated as it can dislodge clots.

Correct Answer: B

Rationale: Muscle weakness is a common finding in clients with hypokalemia, as potassium is essential for proper muscle function. Diarrhea (choice A) is more commonly associated with hyperkalemia rather than hypokalemia. Hypertension (choice C) is not typically a direct result of low potassium levels. Bradycardia (choice D) is more commonly associated with hyperkalemia, not hypokalemia.

Correct Answer: A

Rationale: Spinach is the correct answer because it is a good source of calcium. Since the client has eliminated dairy products due to lactose intolerance, which are a common source of calcium, increasing spinach consumption can help compensate for the lost calcium. Peanut butter, ground beef, and carrots are not significant sources of calcium and therefore not the best choice for this client.
