Correct Answer: B

Rationale: The correct answer is B. Instructing the client to hold their breath for 10 seconds after inhaling the medication allows it to reach deeper into the lungs for maximum effectiveness. Choice A is incorrect because taking one puff every 5 minutes may lead to overuse of the medication. Choice C is incorrect as shaking the inhaler for only 2 seconds may not provide adequate mixing of the medication. Choice D is incorrect because exhaling forcefully after each puff may reduce the amount of medication that reaches the lungs.

Correct Answer: D

Rationale: During early pregnancy, nausea and vomiting are common. Instructing the client to eat dry carbohydrates like crackers before getting out of bed can help alleviate these symptoms. This recommendation helps prevent an empty stomach, which can worsen nausea. High-protein foods (Choice A) may be harder to digest and could exacerbate nausea. Lying down after meals (Choice B) may increase gastric reflux and worsen symptoms. Drinking water with meals (Choice C) may make the client feel fuller, potentially worsening nausea.

Correct Answer: A

Rationale: The most important nursing action when a patient experiences a fall is to assess the patient for injuries. This is critical to identify any potential harm or underlying issues that may require immediate attention. Calling for help and notifying the healthcare provider are important steps, but assessing the patient's condition takes precedence to ensure prompt and appropriate care. Documenting the fall is also necessary but should follow the initial assessment and care provided to the patient.

Correct Answer: A

Rationale: When a patient refuses a blood transfusion for religious reasons, the healthcare provider should respect the patient's beliefs. It is crucial to uphold the patient's autonomy and right to make decisions about their care, even if the provider disagrees. Educating the patient on the importance of the transfusion may be appropriate in some cases, but the initial response should always be to respect the patient's decision. Notifying the healthcare provider is not necessary as the decision lies with the patient. Persuading the patient to accept the transfusion goes against the principle of respecting the patient's autonomy and beliefs.

Correct Answer: C

Rationale: The correct intervention for a client with DVT is to apply cold packs to the affected extremity. Cold packs can help reduce swelling and pain by constricting blood vessels. Massaging the affected extremity can dislodge a clot and worsen the condition. Elevating the affected extremity helps with blood flow but is not the priority intervention for DVT. Performing range-of-motion exercises on the affected extremity can also dislodge a clot and is contraindicated.
