What is the best way to monitor for infection in a patient with a central line?

Correct Answer: A

Rationale: The correct answer is A: Check the central line site daily. Monitoring the central line site daily is crucial in detecting early signs of infection, such as redness, swelling, tenderness, or drainage. By checking the site regularly, healthcare providers can take prompt action to prevent complications. Choice B, monitoring the patient's vital signs, while important in assessing overall health, may not specifically indicate an infection related to the central line. Choice C, checking the central line dressing every other day, may not be frequent enough to catch early signs of infection. Choice D, checking for signs of sepsis, is important but represents a more severe stage of infection and may occur after local signs at the central line site have already manifested.

Correct Answer: B

Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.

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: D

Rationale: The correct answer is to elevate the client's affected extremity when in bed. Elevating the extremity helps to reduce swelling and improve venous return in clients with DVT. Limiting fluid intake to 1500 mL per day (Choice A) is not directly related to managing DVT. Massaging the affected extremity (Choice B) can dislodge a clot and lead to serious complications. Applying cold packs (Choice C) can vasoconstrict blood vessels, potentially worsening the condition by reducing blood flow.

Correct Answer: A

Rationale: In patients with heart failure, monitoring daily weight is the most accurate method for assessing fluid balance. Weight gain can indicate fluid retention, a common issue in heart failure patients. Monitoring input and output (B) is essential but may not always accurately reflect fluid balance. Checking for edema (C) is important as it can indicate fluid accumulation, but daily weight monitoring is more precise. Monitoring blood pressure (D) is important in heart failure management but does not directly assess fluid balance.

Correct Answer: B

Rationale: The correct answer is B because hypnosis during labor aims to increase control over pain perception, helping manage labor pain without the need for medication. Choice A is incorrect as hypnosis doesn't primarily focus on biofeedback. Choice C is incorrect because hypnosis doesn't rely on therapeutic touch. Choice D is incorrect because hypnosis doesn't just provide instructions to minimize pain but rather helps individuals gain control over their pain perception.

Correct Answer: C

Rationale: The correct answer is C: 'Walk for 30 minutes 3 times per week.' Walking is a weight-bearing exercise that helps prevent bone loss and improve overall health in clients with osteoporosis. Option A is incorrect because while calcium is essential for bone health, simply taking a supplement is not sufficient for preventing bone loss. Option B is incorrect because weight-bearing exercises are actually beneficial for improving bone density and strength. Option D is incorrect because high-phosphorus foods do not play a significant role in preventing bone loss in osteoporosis.

Correct Answer: B

Rationale: Administering lorazepam is the appropriate intervention for a client experiencing acute alcohol withdrawal. Lorazepam helps reduce agitation and prevent complications during this withdrawal phase. Choice A, providing a low-sodium diet, is not directly related to managing alcohol withdrawal symptoms. Choice C, keeping the client in a supine position, is not necessary and may not address the client's withdrawal symptoms. Choice D, placing the client in restraints, should only be considered if the client is at risk of harming themselves or others, but it is not the primary intervention for managing alcohol withdrawal.

Correct Answer: A

Rationale: Verifying the patient's identity is a critical step when administering a blood transfusion to ensure that the correct blood product is given to the right patient. This process helps prevent errors and enhances patient safety. Choice B, 'Administer medication,' is incorrect because the focus during a blood transfusion should be on ensuring the correct blood product is administered. Choice C, 'Monitor vital signs,' is also important but comes after verifying the patient's identity. Choice D, 'Start blood transfusion without verification,' is incorrect and unsafe as patient identification verification is essential prior to starting any medical procedure, especially one as important as a blood transfusion.
