Correct Answer: B

Rationale: When caring for a patient with a central line, monitoring for infection is a crucial nursing responsibility. This is essential to prevent complications such as bloodstream infections. While flushing the line with saline and monitoring fluid balance are important aspects of care, they are not as critical as monitoring for infection. Replacing the central line is only done when necessary due to complications or at the end of its recommended use.

Correct Answer: C

Rationale: The correct answer is C: 'Use a new catheter each time you perform self-catheterization.' It is essential to use a new, sterile catheter each time to prevent infection during the procedure. Choice A is incorrect because cleaning the catheter with alcohol may not be sufficient to prevent infection. Choice B is incorrect because self-catheterization is typically done in a clean, private area, not necessarily on the toilet. Choice D is incorrect because lubricating the catheter tip with petroleum jelly is a common practice but not as crucial as using a new catheter each time to prevent infection.

Correct Answer: D

Rationale: A weight gain of 2.3 kg (5 lb) in 1 week can indicate worsening gestational hypertension and should be reported to the provider. Sudden weight gain in a client with gestational hypertension can be a sign of fluid retention, which could worsen the hypertension and lead to complications like preeclampsia. The other options, blood pressure of 140/90 mm Hg, fasting blood glucose of 120 mg/dL, and urinary output of 40 mL/hr, are within normal limits for a client with gestational hypertension and do not pose an immediate concern that requires reporting to the provider.

Correct Answer: C

Rationale: The correct instruction is to take ferrous sulfate on an empty stomach to increase absorption. This is because taking it with food or dairy products like milk can reduce its absorption. Orange juice is not recommended as it may interfere with the absorption of iron. Taking ferrous sulfate on an empty stomach may cause gastrointestinal upset, but this can be minimized by gradually increasing the dose.

Correct Answer: A

Rationale: A low protein diet is the appropriate choice for a patient with chronic kidney disease because it helps to reduce the buildup of waste products in the body, which the kidneys may struggle to filter out. High protein diets can put extra strain on the kidneys by increasing the workload to eliminate the byproducts of protein metabolism. While low sodium and low potassium diets can also be important for managing certain aspects of kidney disease, the primary focus should be on controlling protein intake to lessen the burden on the kidneys.
