Correct Answer: A

Rationale: The correct sequence of events for administering regular insulin and NPH insulin begins with inspecting the vials for contamination to ensure patient safety. Rolling the NPH insulin vial between the hands to mix and injecting air into the NPH insulin vial should follow the inspection step. Afterward, the nurse should inject air into the regular insulin vial and then withdraw the regular insulin first. Option A is the correct answer as it outlines the initial crucial step in the administration process. Option B is incorrect as it provides the incorrect order of withdrawing the insulins. Option C is incorrect as injecting air into the NPH insulin vial should come after inspecting the vials. Option D is incorrect as rolling the NPH insulin vial should be done after inspecting the vials and injecting air into the NPH insulin vial.

Correct Answer: C

Rationale: The correct answer is to give enoxaparin in the abdomen. Enoxaparin is usually administered subcutaneously in the abdomen to avoid muscle irritation. Choice A is incorrect because enoxaparin should not be administered intramuscularly. Choice B is incorrect as monitoring APTT levels is not directly related to administering enoxaparin. Choice D is incorrect as enoxaparin should be administered slowly to prevent bruising or bleeding at the injection site.

Correct Answer: B

Rationale: The correct answer is B: 'Monitor for signs of infection.' After surgery, it is essential for clients to watch for signs of infection, such as increased redness, swelling, or drainage at the incision site. Choice A is incorrect because resuming normal activities immediately after surgery can be harmful. Choice C is incorrect as complete avoidance of physical activity for a month is typically not necessary and can lead to complications like blood clots. Choice D is incorrect as taking pain medications only as needed may not provide adequate pain management post-surgery.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin levels. Ferrous sulfate is used to treat iron deficiency anemia by increasing the body's iron stores. Monitoring hemoglobin levels is crucial as it reflects the effectiveness of the treatment in improving the client's anemia. Serum potassium levels (Choice A) are typically not directly affected by ferrous sulfate. Liver function tests (Choice C) and blood glucose levels (Choice D) are not routinely monitored when a client is receiving ferrous sulfate unless there are specific indications or pre-existing conditions that warrant such monitoring.

Correct Answer: B

Rationale: The correct answer is B: 'Pale skin.' Pale skin is a common sign of anemia due to reduced hemoglobin levels, which affects the skin color. Anemia is characterized by a decrease in the number of red blood cells or hemoglobin in the blood, leading to a paler complexion. Choices A, C, and D are incorrect. 'Increased energy' is not typically associated with anemia, as fatigue is a common symptom. 'Elevated blood pressure' is not a typical finding in anemia; instead, anemia may cause hypotension. 'Weight gain' is not a direct symptom of anemia; in fact, weight loss may occur in some cases due to reduced appetite or other factors associated with anemia.
