Correct Answer: A

Rationale: When drawing medication from a vial, especially for controlled substances like opioids, any wastage must be witnessed by another healthcare professional to ensure accuracy, prevent diversion, and maintain safety standards. This process is crucial for proper documentation and accountability. Recording the amount drawn on the Medication Administration Record (MAR) is important for tracking administered doses and preventing errors. Disposing of the remaining medication in a sharps container is not recommended as it does not address proper wastage documentation. Administering the entire vial of medication just to avoid wastage is inappropriate and can lead to potential harm or overdose in the patient.

Correct Answer: C

Rationale: The correct answer is C: Healthcare-associated infection rate. This measure best indicates the effect of the policy on infection control. By monitoring the healthcare-associated infection rate, it can be determined if the policy of removing acrylic nails has contributed to reducing the risk of infections. Choices A, B, and D are not as directly linked to the outcome of the policy. The number of staff-induced injuries may not be solely due to acrylic nails. Client satisfaction may not be directly impacted by this policy, and needle-stick injuries are more related to a different aspect of healthcare practice.

Correct Answer: A

Rationale: The correct action to ensure the medication reaches the inner ear is to press gently on the tragus of the client's ear. The tragus is the small pointed eminence of the external ear, and pressing on it helps direct the medication deeper into the ear canal. Pulling the ear lobe up and back (Choice B) is the correct technique for administering eardrops to a child, not an adult. Inserting the medication deeply into the ear canal (Choice C) can cause injury or discomfort as the eardrops are designed to flow into the ear canal naturally. Massaging the ear gently after administering the medication (Choice D) is unnecessary and may not help the medication reach the inner ear effectively.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin. Epoetin alfa (Epogen) is a medication commonly used in clients with chronic kidney disease to stimulate red blood cell production. Monitoring hemoglobin levels is crucial to assess the effectiveness of epoetin alfa therapy. Hemoglobin levels reflect the oxygen-carrying capacity of the blood and indicate if the medication is successfully treating anemia associated with chronic kidney disease. Option A, serum creatinine, is a marker of kidney function, not the primary indicator of epoetin alfa effectiveness. Option C, blood urea nitrogen (BUN), is a measure of kidney function and hydration status. Option D, platelet count, assesses clotting ability and is unrelated to monitoring the effectiveness of epoetin alfa in treating anemia in chronic kidney disease.

Correct Answer: C

Rationale: The correct answer is potato chips. As a child with celiac disease needs to avoid gluten, potato chips are a suitable snack choice as they are typically gluten-free. Cheese crackers (Choice A) and vanilla cookies (Choice D) contain gluten, which should be avoided by individuals with celiac disease. While peanut butter sandwiches (Choice B) could be gluten-free depending on the bread used, it is not the best choice as cross-contamination is a concern in shared environments like daycare centers.
