Correct Answer: C

Rationale: The correct answer is to inject the medication into the client's abdomen. Enoxaparin is a medication that should be administered subcutaneously, not intramuscularly. Massaging the injection site after administration is not recommended as it can cause bruising or discomfort. Injecting the medication into the deltoid muscle is also incorrect because enoxaparin should be given in areas of adipose tissue, such as the abdomen, to ensure proper absorption and effectiveness.

Correct Answer: B

Rationale: The correct answer is B: Start the transfusion with 0.9% sodium chloride. 0.9% sodium chloride is the only IV solution that is compatible with blood products and should be used to prime the tubing before a transfusion. Choice A is incorrect because vital signs should be monitored more frequently, typically every 15 minutes at the beginning of the transfusion. Choice C is incorrect as blood transfusions are usually administered over 2-4 hours, not 6 hours. Choice D is incorrect as the first 500 mL of blood should be infused slowly over 1-2 hours to monitor for any adverse reactions.

Correct Answer: D

Rationale: The correct answer is D: Whole milk. Clients with cholecystitis should avoid high-fat foods, and whole milk contains high levels of fat. Bananas, oatmeal, and brown rice are generally considered safe for clients with cholecystitis as they are low in fat and easily digestible. Bananas are a good source of potassium, oatmeal is high in fiber, and brown rice provides complex carbohydrates. Therefore, the nurse should advise the client to avoid whole milk but can recommend the other choices as part of a balanced diet for cholecystitis.

Correct Answer: D

Rationale: The correct answer is D: Decreased deep tendon reflexes. In myasthenia gravis, muscle weakness is a common manifestation, leading to decreased deep tendon reflexes. Bradycardia (choice A) is not typically associated with myasthenia gravis. Increased muscle strength (choice B) is unlikely as muscle weakness is a hallmark of this condition. Diarrhea (choice C) is not a typical finding in myasthenia gravis.

Correct Answer: A

Rationale: The correct answer is A because amniocentesis is a procedure that confirms genetic disorders by analyzing the amniotic fluid surrounding the baby. Choice B is incorrect because amniocentesis is not used to assess lung maturity. Choice C is incorrect because some discomfort or pain may be felt during the procedure. Choice D is incorrect because amniocentesis does not primarily assess the amount of amniotic fluid around the baby.
