A nurse is caring for a client who has chronic obstructive pulmonary disease (COPD) and is experiencing dyspnea. Which of the following actions should the nurse take?

Correct Answer: B

Rationale: The correct answer is to place the client in a high-Fowler's position. This position helps improve breathing by expanding the lungs and aiding in better oxygenation. Encouraging the client to take deep breaths may not be effective in managing dyspnea in COPD as it can lead to fatigue. Administering a bronchodilator may be necessary but placing the client in a high-Fowler's position should be the priority. Administering oxygen at 6 L/min via face mask may also be needed, but positioning is the initial intervention to optimize respiratory function.

Correct Answer: A

Rationale: The correct action for the nurse to take first when a client reports chills during a blood transfusion is to stop the transfusion. Chills can indicate a transfusion reaction, which is a potentially serious situation. Stopping the transfusion immediately is crucial to prevent further complications. Administering acetaminophen or checking the client's blood pressure can come after ensuring the safety of the client by stopping the transfusion. Notifying the provider is important, but the immediate priority is to stop the transfusion.

Correct Answer: B

Rationale: The correct answer is B, Glycosylated hemoglobin (HbA1c). HbA1c provides a measure of long-term blood glucose control over the past 2-3 months. This test reflects the average blood glucose levels during this period, making it a valuable tool in managing diabetes. Choices A, C, and D are not indicators of long-term blood glucose control. Fasting blood glucose measures the current glucose level after a period of not eating, random blood glucose provides a snapshot of the current glucose level, and postprandial blood glucose measures the glucose level after a meal.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Patients on diuretics are at risk of developing hypokalemia due to increased potassium excretion by the kidneys. Hypokalemia can lead to serious consequences such as cardiac arrhythmias. Hyponatremia (choice B) is an imbalance of sodium levels and is not typically associated with diuretic use. Hyperkalemia (choice C) is the opposite condition where potassium levels are elevated and is less common in patients on diuretics. Hypercalcemia (choice D) is an excess of calcium in the blood and is not directly related to diuretic use. Therefore, monitoring for hypokalemia is crucial in patients taking diuretics.

Correct Answer: C

Rationale: Correct! Dry mucous membranes are a common finding in clients with dehydration. Dehydration leads to reduced fluid volume in the body, resulting in dryness of mucous membranes, decreased skin turgor, and thirst. Bradycardia (slow heart rate) is not typically associated with dehydration, as the body tries to compensate for decreased fluid volume by increasing heart rate. Hypotension (low blood pressure) is a possible finding in dehydration due to reduced circulating volume. Tachypnea (rapid breathing) is more commonly seen in conditions like respiratory distress or metabolic acidosis, rather than dehydration.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss in the body, resulting in hypokalemia. Monitoring potassium levels is crucial in patients on furosemide to prevent complications such as cardiac arrhythmias and muscle weakness. Choice B, hyponatremia, is not typically associated with furosemide use. Hyperkalemia (choice C) and hypercalcemia (choice D) are not commonly linked to furosemide therapy; therefore, they are incorrect choices.

Correct Answer: A

Rationale: Correct answer: A. Checking the central line dressing daily is crucial to monitor for signs of infection around the insertion site. This practice helps in early detection of any changes such as redness, swelling, or discharge, which are indicators of a potential infection. Monitoring for signs of redness (choice B) is limited as redness alone may not always indicate an infection; other symptoms like discharge and tenderness should also be observed. Checking for abnormal breath sounds (choice C) is not directly related to monitoring central line infections. Monitoring temperature (choice D) is important for detecting systemic signs of infection but may not specifically indicate an infection related to the central line site.

Correct Answer: B

Rationale: Methimazole is the correct answer. It is commonly used to manage hyperthyroidism by inhibiting the production of thyroid hormones. Levothyroxine (Choice A) is actually a medication used to treat hypothyroidism by supplementing thyroid hormones. Propylthiouracil (Choice C) is another anti-thyroid medication used in the management of hyperthyroidism. Prednisone (Choice D) is a corticosteroid and is not typically used in the treatment of hyperthyroidism.

Correct Answer: B

Rationale: The correct instruction that the nurse should include for a client postoperative following cataract surgery is to avoid bending at the waist. Bending at the waist can increase intraocular pressure, which is not recommended after cataract surgery. Choices A, C, and D are incorrect because lying flat for 24 hours after surgery may not be necessary, wearing an eye patch at night for a week is not a standard postoperative instruction for cataract surgery, and sleeping on the affected side may not necessarily reduce discomfort and can increase pressure on the eye.
