Correct Answer: A

Rationale: For a patient with a small-bowel obstruction, the highest priority action is to maintain nasogastric suction. This helps to decompress the bowel and relieve the obstruction by removing fluid and gas from the gastrointestinal tract. It can also help prevent complications such as bowel perforation and reduce the risk of aspiration if the patient vomits. Managing the obstruction is crucial to prevent further complications and promote the patient's recovery. Administering prescribed analgesics, keeping strict intake and output records, and placing the patient in a semi-Fowler's position are important interventions but may not address the immediate need to relieve the obstruction.

Correct Answer: D

Rationale: In children and adolescents, one of the important risk factors for stroke is head trauma. Head injuries can lead to blood vessel damage, increased risk of blood clot formation, and subsequent stroke. It is crucial for healthcare providers to emphasize the importance of injury prevention and appropriate management of head trauma in this population to reduce the risk of stroke. While hypertension, dysrhythmias, and arteriosclerosis are risk factors for stroke in adults, head trauma is a key risk factor to focus on when educating the community on stroke prevention in children and adolescents.

Correct Answer: B

Rationale: Monitoring the pulse and not taking procainamide hydrochloride if the pulse is less than a specified rate is a crucial aspect of medication adherence for clients receiving this medication. Procainamide hydrochloride is an antiarrhythmic medication that can affect conduction and increase the risk of dangerous dysrhythmias. Therefore, monitoring the pulse rate helps in early identification of potential adverse effects, such as heart block, that may necessitate withholding the medication and seeking medical attention. By adhering to this instruction, the client can actively participate in their care to ensure safe and effective treatment with procainamide hydrochloride.

Correct Answer: B

Rationale: Septic arthritis is a form of arthritis that is considered a medical emergency. It is an acute, severe infection of a joint often caused by bacteria entering the joint space. Prompt recognition and treatment are essential to prevent irreversible joint damage and systemic spread of the infection. Symptoms of septic arthritis typically include severe joint pain, swelling, redness, warmth, and decreased range of motion. The nurse should plan care to facilitate rapid diagnosis, administration of antibiotics, joint drainage if necessary, and close monitoring for complications. Osteoarthritis, gouty arthritis, and reactive arthritis are not medical emergencies and generally require different treatment approaches.

Correct Answer: B

Rationale: The correct statement indicating that teaching was effective is "It's a protein that pulls water into my blood vessels." Albumin is a type of protein found in the blood that helps to maintain blood volume and pressure by pulling water into the blood vessels from surrounding tissues. In the case of a client recovering from hypovolemic shock, infusion of albumin 5% can help to restore blood volume and improve circulation. The other statements do not accurately describe the function of albumin in the body.
