A client is scheduled for a sigmoidoscopy and expresses anxiety about the procedure. What should the nurse do first?

A. Offer information about the procedure steps

B. Administer an anxiolytic before the procedure

C. Encourage the client to discuss their fears

D. Reassure the client that the procedure is common and safe

Correct Answer: C
Rationale: The correct first action for the nurse when a client expresses anxiety about a procedure is to encourage the client to discuss their fears. By allowing the client to express their concerns, the nurse can provide personalized support, address specific worries, and offer tailored information. This approach helps to establish trust, reduce anxiety, and promote a therapeutic nurse-client relationship. Offering information about the procedure steps (Choice A) may be helpful but should come after addressing the client's fears. Administering an anxiolytic (Choice B) should not be the first action as it focuses on symptom management rather than addressing the underlying cause of anxiety. Reassuring the client that the procedure is common and safe (Choice D) is important but should follow active listening and addressing the client's fears.

A client who has just been diagnosed with tuberculosis (TB) is being discharged home. Which instruction is most important for the nurse to provide?

• A. Avoid close contact with others until treatment is complete
• B. Take all prescribed medications as directed
• C. Schedule a follow-up appointment with the healthcare provider
• D. Wear a mask when in public places

Correct Answer: B
Rationale: The correct answer is B: 'Take all prescribed medications as directed.' This instruction is the most important because adherence to the prescribed medication regimen is crucial in treating tuberculosis effectively and preventing the development of drug-resistant TB. While choice A is important for infection control, ensuring treatment adherence through proper medication intake takes precedence. Choice C is also essential for monitoring progress but is not as critical as ensuring medication compliance. Choice D is relevant for preventing transmission but is not as crucial as ensuring proper treatment by taking medications as directed.

Based on the Nursing diagnosis of 'Potential for infection related to second and third degree burns,' which intervention has the highest priority?

• A. Application of topical antibacterial cream
• B. Use of careful hand washing technique
• C. Administration of plasma expanders
• D. Limiting visitors to the burned client

Correct Answer: B
Rationale: The highest priority intervention in this scenario is B, the use of careful hand washing technique. Proper hand hygiene is essential in preventing infection, especially in individuals with compromised skin integrity like those with burns. By practicing careful hand washing, healthcare providers reduce the risk of introducing harmful pathogens to the burn wound, thus lowering the chances of infections. Choice A, application of topical antibacterial cream, is important but should follow ensuring proper hand hygiene. Choice C, administration of plasma expanders, is not directly associated with preventing burn-related infections. Choice D, limiting visitors, is significant for infection control, but ensuring proper hand hygiene outweighs this intervention in terms of priority.

The client with diabetes is being taught about the importance of foot care. Which statement by the client indicates a need for further teaching?

• A. ''I will inspect my feet daily for any cuts or blisters.''
• B. ''I will soak my feet in warm water every day.''
• C. ''I will wear shoes that fit properly to avoid injury.''
• D. ''I will avoid walking barefoot to protect my feet.''

Correct Answer: B
Rationale: Choice B is the correct answer because soaking feet daily can lead to skin breakdown, making it inappropriate for clients with diabetes. Inspecting feet daily for cuts or blisters (Choice A), wearing properly fitting shoes (Choice C), and avoiding walking barefoot (Choice D) are all appropriate measures to maintain foot health for clients with diabetes.

The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

• A. 400 mg/mL
• B. 500 mg/mL
• C. 450 mg/mL
• D. 350 mg/mL

Correct Answer: A
Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.
