Correct Answer: B

Rationale: The correct answer is B: TPN administered via a peripherally inserted central catheter. TPN provides comprehensive nutrition intravenously, bypassing the GI tract, which is important for patients unable to tolerate oral intake. A peripherally inserted central catheter allows for long-term TPN administration. A: Administration of parenteral feeds via a peripheral IV is not ideal for long-term nutrition as it may not provide complete nutrition. C: Insertion of an NG tube may not be feasible due to the tumor location and the patient's inability to tolerate oral intake. D: Maintaining NPO status and IV hydration alone may lead to malnutrition over time as it does not provide adequate nutrition.

Correct Answer: B

Rationale: The correct answer is B: The patient should be monitored for bone marrow depression. Carbamazepine can cause bone marrow suppression, leading to decreased production of blood cells. Monitoring blood counts is crucial to detect this adverse effect early. Choice A is incorrect as Tegretol can have serious adverse effects, including bone marrow depression. Choice C is incorrect as the main side effects of carbamazepine are related to the central nervous system, not renal dysfunction. Choice D is incorrect as medications like carbamazepine should be started at a low dose and gradually titrated up to minimize side effects.

Correct Answer: C

Rationale: The correct answer is C because it includes fiber-rich whole wheat bread, grapes, and walnuts which promote healthy bowel elimination. Whole wheat bread and fruits provide dietary fiber that aids in digestion and prevents constipation. Walnuts are high in omega-3 fatty acids which can also help with bowel regularity. Option A (Broccoli and cheese soup with potato bread) lacks fiber and may cause constipation due to the low fiber content. Option B (Turkey and mashed potatoes with brown gravy) may be low in fiber and high in fat, which can slow down digestion. Option D (Dinner salad topped with hard-boiled eggs, cheese, and fat-free dressing) is a healthier choice but may lack sufficient fiber for promoting healthy bowel elimination compared to option C.

Correct Answer: C

Rationale: The correct answer is C: Avoid lifting objects heavier than 10 pounds. This recommendation is crucial post-mastectomy as it helps prevent lymphedema and promotes healing without causing strain on the surgical site. Lifting heavy objects can lead to complications such as lymphedema or disruption of the healing process. Options A, B, and D are incorrect as avoiding exercise of the arm for 2 months may lead to stiffness and reduced range of motion, keeping cuticles clipped neatly does not directly affect rehabilitation, and using a sling is not necessary unless specifically advised by the healthcare provider.

Correct Answer: A

Rationale: The correct answer is A: 10-mL Luer-Lok syringe. The nurse should use this syringe to obtain a gastric aspirate for pH testing because it allows for accurate measurement of the aspirate volume. Asepto syringe (B) is not suitable for this purpose as it is not designed for accurate measurement. Sterile gloves (C) and double gloves (D) are not equipment used specifically for obtaining gastric aspirate for pH testing. Sterile gloves are used for infection control, and double gloves are used for additional protection during procedures.
