A nurse is caring for a patient who is post-operative following a knee replacement. The nurse should encourage the patient to perform which of the following exercises to prevent complications?

Correct Answer: A

Rationale: The correct answer is A: Quadriceps setting exercises. These exercises help prevent complications by strengthening the quadriceps muscles, which are crucial for knee stability and joint support post-surgery. They also aid in preventing muscle atrophy and promoting blood circulation. Leg lifts with weights (B) may strain the knee joint, leading to complications. Isometric muscle contractions (C) involve static muscle contractions and do not provide the necessary range of motion needed post-knee surgery. Active range-of-motion exercises (D) may be beneficial but should be performed after quadriceps setting exercises to avoid unnecessary strain on the knee joint.

Correct Answer: B

Rationale: The correct answer is B: Assessment. The first step in the nursing process is to assess the patient's condition to gather data and information. In this case, assessing the patient's symptoms, vital signs, and history will help the nurse identify signs of pneumonia and determine the appropriate interventions. Diagnosis (A) comes after assessment, as it involves analyzing the data collected. Implementation (C) and Evaluation (D) are subsequent steps in the nursing process after assessment and diagnosis have been completed. Assessment is crucial for developing an effective care plan and ensuring the best possible outcomes for the patient.

Correct Answer: A

Rationale: The correct answer is A: Administering antihypertensive medication as prescribed. This is the priority intervention because it directly addresses the patient's hypertension, which is a critical condition that needs immediate management to prevent complications. Encouraging weight loss (B), monitoring blood pressure (C), and promoting a low-sodium diet (D) are all important aspects of managing hypertension. However, administering antihypertensive medication takes precedence as it directly targets lowering blood pressure and reducing the risk of cardiovascular events. Weight loss, monitoring, and dietary changes are important for long-term management but may not provide immediate control of hypertension compared to medication.

Correct Answer: C

Rationale: The correct answer is C: Place the patient in the supine position. This position allows optimal access to the abdomen for examination due to gravitational forces aiding in organ palpation. Having the patient lie flat (choice B) may not provide adequate access. Positioning the patient on their side (choice D) may limit visibility and palpation. Elevating the head to 45 degrees (choice A) is unnecessary for an abdominal examination on an obese patient.

Correct Answer: A

Rationale: The correct answer is A: Quadriceps setting exercises. These exercises help prevent complications by strengthening the quadriceps muscles, which are crucial for knee stability and joint support post-surgery. They also aid in preventing muscle atrophy and promoting blood circulation. Leg lifts with weights (B) may strain the knee joint, leading to complications. Isometric muscle contractions (C) involve static muscle contractions and do not provide the necessary range of motion needed post-knee surgery. Active range-of-motion exercises (D) may be beneficial but should be performed after quadriceps setting exercises to avoid unnecessary strain on the knee joint.

Correct Answer: C

Rationale: The correct answer is C: Do they have noninsured health benefits? This is because noninsured health benefits provide coverage for essential health services not covered by other plans for First Nations and Inuit people in Canada. It ensures access to necessary dental care for the family. Incorrect choices: A: Coverage under the Indian Act of 1876 is not directly related to accessing dental care; it pertains to legal and historical rights. B: Living on a reservation or in town may not necessarily impact access to dental care, as healthcare services can vary. D: Having provincial health cards is important for general healthcare, but specific benefits for First Nations may not be covered.

Correct Answer: B

Rationale: The correct answer is B: Respiratory failure. Patients with COPD are at risk for respiratory failure due to impaired gas exchange and respiratory muscle weakness. This can lead to hypoxia and hypercapnia. Monitoring for signs such as increased work of breathing, decreased oxygen saturation, and altered mental status is crucial. Hypoglycemia (A) is not a common complication of COPD. Hyperkalemia (C) is less likely to occur in COPD unless the patient is on medications that can cause elevated potassium levels. Anemia (D) may be present in COPD due to chronic inflammation, but it is not a direct complication that requires monitoring for signs of respiratory failure.

Correct Answer: A

Rationale: The correct answer is A: intuition. Expert nurses develop intuition through years of experience, allowing them to recognize patterns in assessment data and act quickly without conscious labeling. This intuitive response is based on a deep understanding of situations and is often more efficient than consciously going through the nursing process. Clinical knowledge (C) is important but refers to theoretical understanding. The nursing process (B) involves systematic steps in patient care, not the automatic response seen in intuition. Diagnostic reasoning (D) involves a more deliberate thought process in identifying and treating health issues.

Correct Answer: B

Rationale: The correct answer is B: Providing supplemental oxygen. In COPD, patients often have difficulty breathing due to impaired lung function. Supplemental oxygen helps improve oxygenation and relieves respiratory distress. Prioritizing this intervention is crucial for managing COPD exacerbations and preventing complications. Administering diuretics (A) may be indicated for comorbid conditions like heart failure but is not a priority in managing COPD. Increasing fluid intake (C) may not directly address the patient's respiratory distress. Encouraging bed rest (D) may lead to deconditioning and worsen respiratory function in COPD patients.
