A nurse is caring for a patient with asthma. The nurse should educate the patient about using a peak flow meter. What is the primary purpose of this device?

Correct Answer: B

Rationale: The correct answer is B: To monitor the amount of airway obstruction. A peak flow meter is used to measure how well the patient can exhale air from the lungs, indicating the degree of airway obstruction in conditions like asthma. By monitoring peak flow readings, the nurse can assess the severity of the patient's asthma and adjust treatment accordingly. Choices A, C, and D are incorrect: A: To measure the amount of oxygen in the blood - This is the function of a pulse oximeter, not a peak flow meter. C: To measure the frequency of inhaler use - This is not the primary purpose of a peak flow meter, which is specifically used to monitor airway obstruction. D: To track blood glucose levels - This is the function of a glucometer, not a peak flow meter used for asthma management.

Correct Answer: A

Rationale: The correct answer is A: Light therapy. Light therapy is effective for treating sleep problems, stress, and seasonal affective disorders because exposure to bright light can regulate circadian rhythms, improve mood, and alleviate symptoms associated with these conditions. Light therapy helps reset the body's internal clock, promoting better sleep patterns and reducing stress. Exercise (choice B) can also improve sleep and reduce stress, but it may not specifically target seasonal affective disorders. Medication (choice C) and herbal treatments (choice D) are not typically recommended as the first-line treatment for these conditions and may have side effects or limited efficacy compared to light therapy.

Correct Answer: A

Rationale: The correct answer is A because asking the client to describe the voices can help the nurse assess the situation and understand the client's experience better. This can provide valuable information for the nurse to determine the appropriate intervention or treatment. Leaving the client alone (B) may not address the underlying issue and could potentially worsen the situation. Encouraging the client to talk about the voices (C) is helpful, but asking for a description first allows for a more systematic assessment. Telling the client there are no voices (D) is dismissive and denies the client's reality, which can be harmful and ineffective in providing appropriate care.

Correct Answer: B

Rationale: The correct answer is B: "Is there anything else you would like to mention?" This question allows the patient to share any additional information or concerns before concluding the interview. It shows empathy and ensures thorough communication. Choice A is not the best option as it may suggest the nurse is rushing or has overlooked something. Choice C is inappropriate as it lacks empathy and may make the patient feel rushed. Choice D is also incorrect as it shifts the focus to a different topic instead of allowing the patient to express any remaining issues or questions.

Correct Answer: A

Rationale: The correct answer is A (Broccoli, oranges, dark greens) because these foods are high in soluble fiber, antioxidants, and plant sterols which are known to help lower cholesterol levels. Broccoli contains fiber that binds to cholesterol in the gut, oranges are rich in vitamin C and fiber, and dark greens like spinach and kale are packed with antioxidants and fiber. Option B (Fiber-rich foods) is partially correct as fiber can help reduce cholesterol levels, but it is not as specific as the foods mentioned in option A. Option C (Increase intake of omega-3 fatty acids) is not directly related to lowering cholesterol, although omega-3s have other health benefits. Option D (Eliminate fat-rich foods) is not ideal as not all fats are bad for cholesterol, and some healthy fats like those found in avocados and nuts can actually improve cholesterol levels.

Correct Answer: C

Rationale: The correct answer is C: Critical thinking. Critical thinking involves analyzing information, evaluating options, and making sound decisions. When caring for multiple clients with complex care, critical thinking enables nurses to prioritize tasks, anticipate complications, and adapt care plans accordingly. Diagnostic reasoning (A) is important but focuses on identifying specific health issues. Physical assessment (B) is crucial but only addresses one aspect of care. Nursing care plans (D) are essential tools but rely on critical thinking for effective implementation. In conclusion, critical thinking is the key as it encompasses all aspects of problem-solving in complex care situations.

Correct Answer: A

Rationale: The correct answer is A: Administer fluids. In shock, the most crucial intervention is to restore perfusion by increasing circulating volume. Administering fluids helps to improve tissue perfusion and oxygen delivery. This is essential for stabilizing the client's condition. Monitoring cardiac rhythm (B) and blood pressure (C) are important, but addressing the underlying issue of hypovolemia by giving fluids takes precedence. Providing IV antibiotics (D) is not the primary intervention for shock, as the immediate focus should be on restoring blood flow and oxygen delivery.

Correct Answer: A

Rationale: Correct answer: A - Hyperkalemia Rationale: 1. In CKD, impaired kidney function leads to decreased potassium excretion, causing hyperkalemia. 2. Hyperkalemia can result in life-threatening cardiac arrhythmias. 3. Monitoring potassium levels is crucial in CKD management. Summary: B: Hypoglycemia - Not typically associated with CKD, more common in diabetes. C: Hyperglycemia - Common in diabetes, but not a typical complication of CKD. D: Hypercalcemia - Uncommon in CKD, more often seen in hyperparathyroidism.

Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. Anticoagulants are crucial in treating DVT as they prevent blood clots from getting larger and stop new clots from forming. They help reduce the risk of complications like pulmonary embolism. Administering analgesics (B) may help with pain but does not address the root cause. Diuretics (C) are used to treat conditions like fluid retention, not DVT. Applying a warm compress (D) can actually worsen DVT by promoting blood flow. Anticoagulants are the gold standard treatment for DVT.
