Correct Answer: B

Rationale: The correct answer is to ensure oxygen tanks are kept upright and away from heat sources. This is crucial to prevent any potential fire hazard, as oxygen supports combustion. Restricting fluid intake while using oxygen (choice A) is not necessary for oxygen safety. Allowing family members to smoke in designated areas (choice C) poses a significant fire risk. Storing oxygen tanks in a closet when not in use (choice D) is unsafe because proper ventilation is needed to prevent oxygen accumulation.

Correct Answer: D

Rationale: The nurse should prioritize performing a wound culture before administering antibiotics to ensure appropriate treatment. This step helps identify the specific infecting organism and its susceptibility to different antibiotics, guiding effective antibiotic therapy. Changing the dressing daily (Choice A) is important but comes after assessing the infection and initiating appropriate treatment. Cleansing the wound with an antiseptic solution (Choice B) and applying a wet-to-dry dressing (Choice C) are interventions that may be necessary but are secondary to determining the most suitable antibiotic therapy based on the wound culture results.

Correct Answer: B

Rationale: Performing a fundal massage is the priority action in a postpartum client experiencing excessive lochia discharge. Fundal massage helps prevent postpartum hemorrhage by ensuring the uterus contracts effectively. Administering pain medication, checking the baby's heart rate, and applying an ice pack are not the initial interventions needed to address excessive lochia discharge.

Correct Answer: B

Rationale: Corrected Rationale: Monitoring blood glucose levels is crucial in clients receiving TPN because the solution has a high glucose content. This monitoring helps prevent hyperglycemia and allows for timely adjustments in the TPN formulation if needed. Monitoring the client's temperature (Choice A) is not directly related to TPN administration. Administering insulin (Choice C) should be based on blood glucose levels and the healthcare provider's orders; it is not a standard intervention for all clients on TPN. Monitoring daily fluid intake (Choice D) is important for overall fluid balance but is not as critical as monitoring blood glucose levels specifically for clients on TPN.

Correct Answer: D

Rationale: The correct instruction the nurse should include in teaching a client with dumping syndrome is to 'Avoid foods high in sugar content.' Dumping syndrome occurs when high-sugar foods move too quickly into the small intestine, leading to symptoms like abdominal cramps, diarrhea, and bloating. By avoiding foods high in sugar content, the client can reduce these symptoms. Choices A, B, and C are incorrect. Drinking plenty of fluids after meals may exacerbate symptoms by speeding up the movement of food through the digestive system. Increasing sugar intake would worsen dumping syndrome symptoms. While eating smaller, more frequent meals is a good strategy, the key emphasis should be on avoiding high-sugar foods.
