Correct Answer: B

Rationale: Before administering platelets, it is crucial to check the integrity of the container holding the blood product. An intact container ensures the sterility and safety of the platelets, minimizing the risk of contamination or infection. Option A is incorrect as administering platelets typically does not require starting a new IV line unless indicated for the specific patient. Option C is not the priority as verifying the client's identity can be done at any point during the administration process but is not specific to the platelet transfusion itself. Option D, checking the client's chart for antibiotic use, is not directly related to ensuring the safety of the blood product container.

Correct Answer: A

Rationale: During CPR, chest compressions should be applied at a rate of 100 compressions per minute in order to effectively circulate blood and oxygen to vital organs. Option A, '100 per minute,' is the correct answer as it aligns with the recommended compression rate in CPR guidelines. Option B, '60 per minute,' is incorrect as it is too slow and may not provide adequate circulation. Option C, 'As quickly as possible,' is vague and does not specify the recommended compression rate. Option D, '200 per minute,' is incorrect as it exceeds the recommended rate and may not be as effective in maintaining perfusion.

Correct Answer: D

Rationale: To reduce the risk of falling at home for an elderly client with decreased visual acuity and using a cane for mobility, installing non-slip pads in the shower or bathtub is crucial. This measure helps prevent slips and falls in areas where water accumulation may occur. While taking off shoes and wearing socks may seem comfortable, it increases the risk of slipping. Limiting activities to the lower level of the home may restrict the client's independence and quality of life unnecessarily. Keeping a lamp near the door of every room may improve visibility but does not directly address the risk of falls associated with mobility and visual acuity issues.

Correct Answer: C

Rationale: When caring for a client requiring droplet precautions, it is essential for the nurse to wear a mask when within 3 feet of the client. This practice helps prevent the transmission of droplet particles that may be produced when the client coughs or sneezes. Assigning the client to a negative-pressure room is not typically necessary for droplet precautions unless specifically indicated for airborne precautions. Using sterilized equipment when sharing between clients with pertussis is important for infection control but does not directly relate to droplet precautions. Therefore, the correct action to uphold droplet precautions in this scenario is to wear a mask when coming within close proximity to the client.

Correct Answer: B

Rationale: The correct answer is to advise the client to avoid any activities that could lead to injury when taking warfarin. Warfarin is an anticoagulant medication that decreases blood clotting, increasing the risk of bleeding. Engaging in activities that may result in injury can lead to uncontrolled bleeding, which can be serious. While monitoring white blood cell count is not specifically related to warfarin therapy, avoiding leafy green vegetables is important due to their vitamin K content, which can interfere with warfarin's effectiveness. Therefore, the client should be educated to avoid activities that could cause injury to prevent potential bleeding complications.
