Correct Answer: C

Rationale: Step 1: Mr. Franco's condition suggests he may need support and positioning. Step 2: Sandbags provide stability and trochanter rolls prevent hip rotation. Step 3: These help prevent pressure ulcers and maintain proper body alignment. Step 4: Hand bell and bed linen are not essential for Mr. Franco's immediate care. Step 5: Footboard and splint may not be relevant to his specific condition. Step 6: Suction machine and gloves are important but not as crucial as positioning aids for Mr. Franco. Summary: Choice C is correct as it directly addresses Mr. Franco's needs for support and positioning, while the other choices are less relevant or not as essential in this context.

Correct Answer: A

Rationale: The correct answer is A: Peripheral vision. When testing visual fields, the nurse evaluates the ability to see objects outside the direct line of sight, which is indicative of peripheral vision. Peripheral vision helps detect objects and movement in the side vision. Distance vision (B) refers to the ability to see clearly at a distance, while near vision (C) pertains to close-up vision. Central vision (D) is essential for focusing on details and seeing straight ahead. Therefore, A is the correct choice as it specifically pertains to the assessment of visual fields.

Correct Answer: A

Rationale: The correct answer is A: Potential for infection. The decreased WBC count indicates reduced ability to fight off infections, making this the priority nursing diagnosis. Normal RBC count rules out anemia-related complications. Decreased HCT and Hgb indicate possible anemia but do not directly relate to infection risk. Choices B and C are not as critical as the potential for infection due to the significant impact on the individual's health and well-being. Choice D, fluid volume excess, is not directly related to the blood test results provided.

Correct Answer: C

Rationale: The correct answer is C because Neomycin is given preoperatively to decrease and retard the growth of normal bacteria in the intestines. This helps reduce the risk of infection during surgery by minimizing the number of bacteria present in the colon. Options A, B, and D are incorrect because Neomycin is not given to prevent infection postoperatively, eliminate the need for preoperative enemas, or treat cancer of the colon. The main purpose of administering Neomycin in this scenario is to create a sterile surgical field by reducing the normal flora in the intestines.

Correct Answer: C

Rationale: Rationale: Step 1: Coughing is the primary way TB bacteria are spread. Step 2: By coughing into a handkerchief or tissue, the TB bacteria are contained. Step 3: Washing the handkerchief in hot water or discarding it prevents the bacteria from spreading. Step 4: This method reduces the risk of infecting family members. Summary of Incorrect Choices: A: Wearing gloves does not prevent airborne transmission of TB. B: Keeping windows closed can increase the concentration of bacteria in the air. D: Boiling water is not necessary to prevent TB transmission.
